The acute effects of hyperglycemia in cognitive function and mood are not well elucidated. The aim of this study was to evaluate whether acute hyperglycemia alters the exploratory behavior of adult zebrafish. Fish were maintained aquariums containing 55 mM D-glucose solution for 14 days. Blood glucose levels and behavioral analysis were assessed before and after the D-glucose challenge. Immersion of adult zebrafish in a 55 mM D-glucose solution (14 days) increased blood glucose levels until the 14th day. There was no difference in weight gain between the two groups. Hyperglycemia did not induce anxiogenic or anxioly-tic behavior, nor did it alter the locomotor activity of the animals. We conclude that acute hyperglycemia does not alter the exploratory behavior of the adult zebrafish.
The emergence of multidrug-resistant bacteria in animals and their products has highlighted the considerable value of the potential transfer of resistance to the human population via the food chain. The objective of this work was to study the antibiotic resistance profile of staphylococci of human and animal origin and to compare the two profiles in order to define an effective therapeutic and preventive strategy. This work was carried out on a set of 97 strains of staphylococci isolated from animal and human biological liquids. The isolation and identification was done by conventional methods. The determination of the minimum inhibitory concentrations (MIC) was studied by the reference method (dilution in agar medium) and VITEK 2® with respect to eight (8) antibiotic molecules. The results were interpreted according to the ACFSM criteria (2001). The results showed higher resistance of human bacteria to penicillin (72.22% vs. 30.23%) erythromycin (50% vs. 18.6%) and gentamicin (33.33% vs. 9.3%) compared to animal bacteria. On the other hand, the resistance to fosfomycin of staphylococci of animal origin was higher (60.46%) compared to human strains (38.89%). Indeed, it seems that vancomycin and rifampicin are the antibiotics of choice against these pathogenic strains in veterinary and human medicine.
The most common organism-type causing orthopedic foreign body infection is the staphylococci, of which Staphylococcus aureus and Staphylococcus epidermidis are especially common. These organisms form biofilms on orthopedic foreign body surfaces, rendering such infections challenging and time consuming to treat. Our group evaluates novel therapeutics for orthopedic foreign body infection in animal models. A current limitation of most animal models is that that they only allow for the removal of one sample per animal, at the time of sacrifice. Herein, we describe a novel rat model of foreign body osteomyelitis that allows removal of foreign bodies at different time points, from the same infected animal. We demonstrate that this model can be used for both S. aureus and S. epidermidis orthopedic foreign body infection, with 3.56, 3.60 and 5.51 log10 cfu/cm2 S. aureus recovered at four, five and six weeks, respectively, after infection, and 2.08, 2.17 and 2.62 log10 cfu/cm2 S. epidermidis recovered at four, five and six weeks, respectively, after infection We evaluated the model with S. aureus infection treated with rifampin 25 mg/kg twice daily for 21 days. Using quantitative cultures, we were no longer able to detect bacteria as of the 14th day of treatment with bacteria becoming detectable again 7 days following die discontinuation of rifampin a period. This novel model allows monitoring of evolution of infection at the infection site in the same animal.
The aim was to examine the expression of tight junction proteins, namely claudins 1 and 5 (CLD1 and 5) and the effects of probiotics-feeding on their expression in the gastrointestinal tract. In experiment 1, the expression of CLD1 and 5 was examined in chicks fed with starter rations for 7 days post-hatching. At day 7 the proventriculus, ileum, cecum and colon were collected for RT-PCR analysis of CLD1 and 5 gene expression. In experiment 2, the chicks were arranged in 3 groups: control group, probiotics group I and probiotics group II, which were fed with starter rations containing 0, 0.2 or 0.4% probiotics, respectively, for 14 days. The proventriculus, ileum, cecum and colon were collected in all groups at D0, D7 and D14 for analysis of CLD1 and 5 expressions by real time PCR. The expressions of CLD1 and 5 were detectable in all segments. Probiotics-feeding did not affect the expression of the CLD1 at D7 and D14 in the proventriculus, ileum and cecum. However, in the colon the expression of CLD1 was higher in probiotic group I than control and probiotics group II. The expression of CLD5 did not show significant differences except in the colon at D7 where control group was higher than that of D0 and D14 and higher in probiotic group I than probiotics group II. These results suggest that probiotics-feeding may not have effects on the gene expressions of CLD1 and 5 in the proventriculus, ileum and cecum. In contrast, probiotics-feeding may enhance the expression of CLD1 in the colon of broiler chicks. This result suggest that probiotics-feeding enhanced the expression of CLD1 in the colon and may help in maintaining tight junction functions and reducing the risk by pathogenic invasions.
Diabetes mellitus is a lethal metabolic disorder in humankind, which induce chronic complications. The present study investigated the effects of ethyl acetate extract from C. procera (EAE) and its isolates on antioxidant and in vitro antidiabetic activities, along with effects of EAE on plasma blood glucose concentrations in STZ-diabetic rats. For the first time, two known metabolites- N-((2S,3R,E)-1,3-dihydroxyoctadec-4-en-2-yl)stearamide (1) and N-((2S,3R,4E,8E)-1,3-dihydroxyoctadeca-4,8-dien-2-yl)palmitamide (2) are reported from EAE. 1, 2 and EAE depicted significant DPPH, superoxide free radicals, α-glucosidase and α-amylase inhibitory profile, indeed, 1 and 2 showed mild inhibitory profile against aldose reductase. In addition, the EAE (200 mg/kg b.w) revealed significant reduction in plasma glucose, body weight, total cholesterol, total glycerides and LDL levels in STZ-induced diabetic rats. The HDL levels were markedly augmented in EAE treated diabetic rats, when compared with control group. EAE abolished the increased lipid peroxidation in pancreas, liver and kidneys. The histopathological examination of pancreas of EAE protected the Langerhans islets with the number of islet cells were found statistically significant, when compared to diabetic control pancreas. Our data suggest that the C. procera has a potentiality to act against diabetes (both, in vitro and in vivo models) by inhibiting particularly digestive enzymes namely α-glucosidase and α-amylase, however further studies are required for proper establishment of mechanism of action and validating clinical effects.
Mycotoxins are toxic metabolites mainly produced by Aspergillus spp. fungi. Further fungal characterization and mycotoxin estimation in feed are crucial measures for animal health and safety. The aim of this study was to identify and characterize mycotoxin-producing fungi in poultry feed. Forty poultry ration samples were collected and were subjected to morphological and molecular as well as to phylogenetic analyses of Aspergillus section Nigri. On average, 40% (16 of 40 samples) were contaminated with Aspergillus section Nigri fungi. Moreover, A. niger and A. tubingensis were identified and characterized in the contaminated poultry feed using molecular and phylogenetic analyses. Furthermore, our results showed that ochratoxin A was produced by some fungal isolates indicating their mycotoxigenicity. In conclusion, A. niger and A. tubingensis contaminate poultry feed and can produce mycotoxins under optimal conditions. Furthermore, several preventive and control measures should be undertaken to reduce the occurrence of fungal contamination and toxin production in poultry rations.
Olive tree leaves have been widely used in traditional remedies in European and Mediterranean countries and in the human diet as extracts, herbal teas, and powder, which contain several potential bioactive compounds that may have antihypertensive, antiatherogenic, anti-inflammatory, hypoglycemic, hypocholesterolemic, antidiabetic and antioxidant activities. The present study was carried out to evaluate the role of olive leaves extracts (OLE) in ameliorating the metabolic changes in rats treated with carbon tetrachloride (CCl4). Forty-eight male rats were classified into six groups; the first group was the control which received 1 ml distilled water, the second group was treated daily with oral dose of cold OLE (1 ml/kg) for one month, the third group was treated daily with oral dose of boiled OLE (1 ml/kg) for one month, the fourth group was treated daily with oral dose of CCl4 (1 ml/kg) for one month, the fifth group was treated with both cold OLE and CCl4 (1 ml/kg for each) for one month and the sixth group was treated with both boiled OLE and CCl4 (1 ml/kg for each) for one month. Serum levels of thiobarbituric acid reactive substance (TBARS), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), urea, creatinine, insulin and glutathione (GSH), catalase (CAT), albumin, total protein, free triiodothyronine (FT3) , free thyroxin (FT4) were measured in serum. Histological examination of hepatic tissue was examined. The results showed that administration of CCl4 to rats induced significant increase (P<0.05) in serum levels of thiobarbituric acid reactive substance (TBARS), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma- glutamyl transferase (GGT), lactate dehydrogenase (LDH), urea, creatinine, insulin and significant decrease (P<0.05) in glutathione (GSH), catalase (CAT), albumin, total protein, free triiodothyronine (FT3) and free thyroxin (FT4). The histological examination of hepatic tissue showed some degenerative changes while significant improvement in biochemical and histological changes was observed either in CCl4 + cold OLE or CCl4 + boiled OLE groups. It could be concluded that the protective effect of olive leaves extract either cold or boiling may be attributed to its antioxidant properties. The obtained results indicated that both cold and boiled olive leaves extract has potent effect to restore the antioxidant status, hepato-renal function, insulin and thyroid hormones near to the control levels.
Tea is the most common drink worldwide besides water. It is rich in antioxidant polyphenolic flavonoids. Further, it has anti-apoptotic, anti-inflammatory, and autoantigen-inhibitory properties. To evaluate the effects of oral administration of aqueous extract of green tea against experimental aflatoxicosis on the renal tissues of adult male albino rats. Twenty five adult male rats were included and they were divided equally into 5 groups: Group 1 (aflatoxin group): the rats received aflatoxins (2.5 mg/kg diet for 15 days), group 2 (aflatoxins and green tea aqueous extract group) for 15 days, group 3, the rats received aflatoxins for 15 days and aqueous extract of the green tea for 30 days, group 4 (green tea aqueous extract group) and group 5(control negative group). Detailed non-traditional histological and morphometrical analyses for renal tissues stained with Hematoxylin and Eosin, Masson's trichrome stain, Periodic Acid Schiff’s (PAS), Alizarin red S stains and immunohistochemical detection of Ki-67 were done. The main observed renal lesions in rats received aflatoxins were dilatation of the renal pelvis, increases in glomerular areas (GA), widening of Bowman's spaces and necrosis of the renal lining epithelium and proliferation of fibrous connective tissues. Morphometric analysis revealed the presence of significant difference between group I and the other experimental groups. Meanwhile, groups 2 and 3 revealed a significant improvement in the histological changes and decrease in most of parameters. The highest percentage of PAS positive reaction was significantly found in group 4. Quantitative analysis of positive reactions of Ki-67 revealed the highest positive immunohistochemical reactions were detected in group 1 which significantly different in groups 4 and 5. In conclusion, green tea has a protective effect against the adverse effects of aflatoxins on renal tissues evidenced by improvement of histopathological alterations and regulation of Ki-67 expressions.
The liver of reptiles is considered an important study model for the interaction between environment and hepatic tissue. Little is known about the histology of the liver of reptiles. The aim of the current study was to elucidate the histological architecture of the liver of the Nile monitor (Varanus niloticus). Liver fragments from the Nile monitor were collected in the summer season and processed for the light and electron microscopy. The liver of the Nile monitor was bi-lobed and the right lobe was found to be larger than the left lobe. Histological examination revealed indistinct lobulation of the liver, and the central vein, sinusoids and portal area were haphazardly organized. The hepatic parenchyma consisted of hepatocytes arranged in glandular-like alveoli or tubules separated by a network of twisted capillary sinusoids. The hepatocytes were polyhedral in shape with vacuolated cytoplasm and the nucleus was single rounded, eccentric, large and vesicular with a distinct nucleolus. The hepatocytes contained numerous lipid droplets, abundant glycogen granules and well-developed RER and mitochondria. The hepatocytes appeared to secrete into the bile canaliculi through the disintegration of their dark cytoplasm into the bile canaliculi. The space of Disse separating between the hepatocytes and sinusoids contained many recesses. The portal area contained branches of the portal vein, hepatic artery, bile duct and lymphatic vessels embedded in a connective tissue. Some non-parenchymal cells were described such as Kupffer cells, heterophils, melano-macrophages, intercalated cells, myofibroblasts in addition to the endothelium of the sinusoids. This is the first report about the histological structure of the liver of the Egyptian Nile monitor. The result presented here should be considered a baseline knowledge to compare with the pathological affections of the liver in this species.
In the current report, a preliminary observation to study the adverse effects of the broad use acaricides fipronil (FPN) in rabbits infested with Psoroptes cuniculi. Two separate groups (5 rabbits/each) treated topically (poured on at the base of the neck) with fipronil 5%, 1 vial/ 10 kilogram body weight (kg bw) and 1 vial/ 5 kg bw. After FPN spot on application, rabbits in both groups examined microscopically on the 7th, 14th, and 28th day post treatment and the number of live mites (larvae, nymphs, and adults) on each rabbit counted at the end of the experiment (28th day). The results showed that the number of mites in rabbits topically treated with FPN did not show significant decrease, moreover a decrease in both treated rabbits body weight (bw) and in performance observed clearly, with some attendant mortality. In conclusion, this work showed that FPN was with limited efficacy on P. cuniculi and had some undesirable side effects. Further and in-depth studies on FPN toxicity in rabbits and other animals are necessary.
Neurotransmitters are mediators inside the nervous system responsible for transmitting neural-neural or neural-organs signals. Several neural studies have tried to unveil the role of such mediators whose action extended outside the nervous system such as immune, digestive, circulatory and reproductive systems. The present study aimed to investigate the role of the excitatory-glutamate and inhibitory-GABA transmitters in female rats reproduction including their effects on gonadotropins; luteinizing hormone (LH) and follicle stimulating hormone (FSH) and the sex steroids; estrogen (E2) and progesterone (P4) during the estrous cycle as well. Furthermore, the responsive changes on the ovarian tissue were also studied. Synthetic glutamate and GABA were injected intraperitoneally (ip) in those animals throughout four successive estrous cycles. Interestingly, the ip injections of glutamate increased the levels of LH, E2 and P4 but decreased those of FSH significantly. However, the ip injections of GABA significantly decreased the levels of LH in the 4th cycles and FSH throughout treatment period while it increased the levels of E2 and P4. All changes occurred in those reproductive hormones caused by glutamate has been recovered after cessation of glutamate and GABA injection except FSH, including; the 5th, 6th and 7th cycles. Regarding to histopathological examination, ovaries of treated rats showed deleterious changes. The glutamate-treated rats ovaries showed atrophy of the primary follicles with degenerative changes in those secondary and tertiary follicles with obvious degeneration in the granulosa cell layer with vacuolated cytoplasm. On the other hand, those received GABA showed degeneration of the oocytes with congestion of blood vessels supplying the corpora lutea (CL) associated with endothelial changes. The histopathological changes in CL have been improved after glutamate cessation while not changed after GABA cessation.
It has been reported that peroxisome proliferator-activated receptor (PPAR)-gamma agonist, pioglitazone, has several beneficial roles in many pathological states of nervous tissues. Then in the present study, we aimed to examine the neuroprotective actions of pioglitazone (PPAR-gamma agonist) on motor function, histopathological changes and oxidative damage during spinal cord injury (SCI) in rats. Twenty-four male Wistar rats were randomly divided into three groups as follows; sham, control injury and pioglitazone-treated injured groups. SCI was performed according to the Ping-Weight Drop (contusion) model in rat. The animals received pioglitazone (3 mg/kg) intraperitoneally at times of 15 min after injury and then each 12 hours for seven days. At day seven after SCI, the malondialdehyde and glutathione levels were assessed using biochemical techniques. Histopathological alterations in injured spinal cord and motor function recovery were also assessed after six weeks. Induction of SCI in control group significantly increased the malondialdehyde levels (56%, P=0.002) and decreased the content of glutathione (39±4 nMol/mL) compared to control group (49±6 nMol/mL). Pioglitazone in treated injured rats significantly decreased the malondialdehyde levels (37%, P=0.018) but not glutathione levels (42±1 nMol/mL) compared to sham group. In addition, pioglitazone noticeably improved the histopathological changes of injured spinal cord but not motor function. Our findings revealed that pioglitazone decreases histopathological changes and oxidative damage of injured spinal cord. However, it is suggested that pioglitazone must be applied at higher doses for improving motor function during SCI.
Heat stress is exposing birds to degrees of temperature higher than the optimal, which results in numerous health problems i.e. respiratory deficits decrease feed intake and thus lower weight at marketing age. Heat stress represents one of the most important factor that has negative effects on poultry production. Heat stress also leads to negative effects on the carcass properties and thus lower meat quality, consequently leads to severe shortage in the market. Most important solutions are using feed additives that have positive effects for resisting thermal stress. Betaine that has several other beneficial effects of mild heat stress. Most of the trials were reported slight positive effects; however, systematic results were rare. Since there are almost unlimited possibilities concerning dosage and products of betaine there is still more research required. Nevertheless, there is still further research under more standardized conditions needed to evaluate the right dosage and combination as well as the exact mechanism of actions of anti-stress effects of betaine.
Emphysema is a chronic pulmonary disorder characterized by the destruction and enlargement of the gas exchanging units known as alveoli. Chronic inflammation is one of the critical features associated with pathogenesis of emphysema. The inflammatory mediators generated during emphysema are thought to be infiltrated into the circulatory system, leading to systemic inflammation and thus, affecting other vital organs. The potential role of ATRA, an anti-inflammatory bio-molecule, towards molecular mechanisms governing systemic inflammation due to inflammatory mediator’s overspills in emphysema is poorly understood. Therefore, the present study deals with investigating the potential effect of ATRA on physiological functions of liver tissue in an established elastase induced emphysema rat model. Three experimental groups (i.e., control, SS; emphysema, ES; and therapy, EA) were prepared. Subsequently, liver from each rat was collected for elastase activity assay, histopathology, real-time PCR based mRNA expression analyses, total lipid estimation and western blot analysis. ATRA supplementation in emphysema group decreases elastase activity. Liver histopathology photomicrographs clearly shows an increase in number of Kupffer cells in ES than SS, while, a decrease in number of Kupffer cells was found in EA. Furthermore, upon validation at mRNA and protein level, expressions of TNF-α, enzymes of gluconeogenesis and triglyceride biosynthesis pathway were significantly increased in ES while decreased in EA when compared to SS. Therapeutic supplementation of ATRA posed a beneficial effect in maintaining the normal architecture of liver tissue along with modulation of gluconeogenesis and triglyceride biosynthesis pathways.
The aims of the present study are to clarify the effect of methyl-beta-cyclo-dextrin (MβCD) on the secretions of luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL) and growth hormone (GH) from the anterior pituitary (AP) cells of prepubertal male cattle and to compare the characteristics of secretion to those of gonadotrophic-releasing hormone (GnRH), thyrotropin- releasing hormone (TRH) and growth hormone-releasing hormone (GHRH), respectively. The AP cells prepared from six castrated Holstein calves (age: 8-11 months) were incubated for 2 h with MβCD (10-3 M, 10-2 M), GnRH (10-8 M), TRH (10-8 M) and GHRH (10-8 M) or vehicle only as a control (CTL). The amount of LH, PRL and GH released in the medium was measured by a time-resolved fluoroimmunoassay (TRFIA). The amount of FSH released in the medium was measured by the radioimmunoassay (RIA). MβCD significantly (P<0.05) stimulated the secretion of LH, FSH, PRL and GH from the AP cells. Furthermore, GnRH significantly (P<0.05) stimulated the secretion of LH and FSH. Also, TRH and GHRH significantly (P<0.05) stimulated the secretion of PRL and GH, respectively. However, the potency of the MβCD was less compared to each respective hormone secretions in response to GnRH, TRH and GHRH (P<0.05).
Peripheral nerve injuries (PNI) are a frequent and disabling condition which affects 13 to 23 per 100,000 persons each; it remains a major cause of morbidity and social disruption. The aim of this study is to evaluate the possible therapeutic potency of melatonin (100 mg/kg) or resveratrol (100 mg/kg) in enhancing the recovery after Schwann cells transplantation in injured sciatic nerves of albino rats in an attempt to overcome multiple factors that limit axons growth after injury. Recovery of function was analyzed by biochemical quantification of malondialdehyde (MDA) and total antioxidant capacity levels, assessment of the sciatic function index (SFI) based on walk track analysis, measurement of brain derived neurotrophic factor (BDNF) mRNA levels as a relative ratio to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) by using real time polymerase chain reaction (RT-PCR), electrophysiological assessment and histopathological evaluation. The results showed that there were significant improvements in serum MDA and serum total antioxidant capacity levels, the relative expression of BDNF mRNA by RT-PCR, the SFI values, the electrophysiological evaluations and the histopathological examinations after intralesional injection of SCs and its combination with melatonin or resveratrol when compared with the sciatic nerve injured untreated group, but the combined groups (SCS and melatonin and SCs and resveratrol treated groups) were significantly superior to the SCs cells only treated group in most of the assessments. We proved the presence of the transplanted cells in the injured tissue by the immunohistochemistry.
Mitochondrial dysfunction with increased production of reactive oxygen species (ROS) is a characteristic feature of diabetes which is associated with damage of mitochondrial DNA (mtDNA). Alcohol metabolism generates ROS with enhanced oxidative stress leading to damage of cellular constituents including mtDNA. The aim of the present study is to investigate the impact of alcohol consumption on hepatic mtDNA damage in diabetic rats. MtDNA was isolated from hepatic tissues of non-diabetic and streptozotocin induced diabetic rats after alcohol treatment. Comprehensive screening of mtDNA displacement loop (D-loop) was carried out by PCR-Sanger’s sequencing analysis. MtDNA deletions were analyzed by long-extension PCR. Furthermore, activities of enzymatic and non-enzymatic antioxidants were measured in hepatic tissue of all rats. Our results showed increased frequency of D-loop mutations in alcoholic-diabetic rats when compared to diabetic or alcoholic non-diabetic rats. DNA mfold analysis predicted higher free energy for 15507C, 15560T and 16116C alleles compared to their corresponding wild alleles which represents less stable secondary structures with negative impact on overall mtDNA function. MtDNA deletions were observed in all experimental groups except controls. Markedly decreased activities of antioxidant enzymes viz., GPx, SOD, catalase and GSH content was identified in alcoholic-diabetic rats when compared to remaining groups. In conclusion, decreased GSH content and lowered activity of catalase, SOD and GPx favor the environment for oxidative stress, which might lead to exacerbation of hepatic mitochondrial DNA damage in diabetic rats receiving alcohol.
Asthma is a chronic inflammatory disorder of the airways. It is characterized by an inflammation of the airways causing dysfunction. Asthma is associated with widespread airflow obstruction and increase in airway responsiveness to a variety of stimuli. An asthma attack is accompanied by wheezing, shortness of breath, chest tightness and coughing. The anti-asthmatic and anti-cough activities of the essential oils and 1,8-cineole on rats were assessed. These activities were induced and challenged with histamine and acetylcholine using an ultrasonic nebulizer for asthma and exposure to ammonia for coughs. Anti-inflammatory activities of the essential oils and 1,8-cineole were determined using the cotton pellet granuloma test. Muscle contraction studies where carried out using the vascular reactivity on aortic smooth muscle. The oils exhibited concentration dependent anti-asthma and anti-cough activities. Significantly, 1,8-cineole isolated and purified from the essential oil showed a concentration dependent anti-inflammatory, anti-cough and anti-asthma activity and The essential oils showed vasorelaxant activity. The ability of the essential oils and 1,8-cineole to directly dilate smooth muscle and relieve the stress of bronchial contraction and obstruction of the airways passage validates the use of Eucalyptus grandis as an anti-asthmatic and anti-cough agent. It is concluded that the essential oils have the potential to be used as an anti-asthma and anti-cough therapy. This study also justifies its use by traditional healers in the treatment of asthma and coughs in Zulu folklore medicine.
Twenty four male albino rats were divided equally into three groups; the first group was the control one which was treated with distilled water for 14 days, the second group was administered cadmium chloride (CdCl2) with oral dose of 22 mg/kg/b.wt./day for 14 days by gavage using a stomach tube and the third group was injected intraperitoneally 14 days post-cadmium chloride with a dose of 75x106±5 bone marrow cells (BMC) then examined after 7 days. The results showed that administration of CdCl2 to rats induced significant increase in thiobarbituric acid reactive substances (TBARS), urea, creatinine, alkaline phosphatase (ALP) and acid phosphatase (ACP) while catalase (CAT), glutathione (GSH) and testosterone levels were significantly decreased. The histological examination of renal and testicular tissues revealed that CdCl2 treated rats showed some degenerative cells in these tissues while treatment with BMC minimized such damages i.e. improvement in biochemical and histological changes were observed in CdCl2 rats treated with BMC. In conclusion, treatment of male rats with bone marrow cells can ameliorate the hazardous effects induced by CdCl2 and manifested by biochemical and histological changes.
