Abstract The purpose of the current investigation was to determine hepatoprotective effect of bioactive compound (-)-epicatechin in hepatitis old age rats. Animals are pre-treated with (-)-epicatechin at a dose of 50 mg/kg/bw for 21 days, and D-galactosamine was used to induce hepatitis on the last two days of the treatment period. For assessment of (-)-epicatechin impact on hepatitis, we analyzed hepatic damage markers AST, ALT, AKP, and γGGT in blood plasma, as well as antioxidant enzymes such as SOD, GPx, GR, GSH, CAT, GST, and MDA in the liver tissue. Further, to strengthen (-)-epicatechin effect, we also done molecular expression studies of TNF-α, IL-6 and TGF-βwith RT-PCR and also examined histological alterations in liver tissues. Our results revealed that SOD, GPx, GR, CAT, activities and GSH content are decrement in hepatitis animals. Besides, GST, ALT, AST, AKP, γGGT activities and MDA are increment in hepatitis subjects. However with (-)-epicatechin treatment all these antioxidant enzymes and liver enzymes are normalized. Interestingly, gene expression markers are downregulated with bioactive compound treated hepatic rats whereas upregulation of them have been observed in the diseased rats. Deterioration of sinusoids, central vein, and hepatocytes are observed in hepatitis ratsx. But with (-)-epicatechin supplementation in hepatitis rats. we examined the regeneration of central vein, sinusoids and hepatocytes in liver tissue of hepatitis animals. From our study,we conclude that (−)-epicatechin supplementation in old hepatitis rats, all the antioxidant enzymes, liver markers, gene expression markers and histopathologcial studies proved that has beneficial effects in hepatitis subjects.
The present study investigated the cardioprotective properties of 6-gingerol against alcohol-induced ROS-mediated cardiac tissue damage in rats. Experiments were conducted on 4 groups of rats, orally treated with control, 6-gingerol (10 mg/kg body weight), alcohol (6 g/kg body weight) and combination of 6-gingerol plus alcohol for two-month. In the results, we found 6-ginger treatment to alcohol-fed rats substantially suppressed ROS production in cardiac tissue. Alcohol-induced elevated 8-OHDG and protein carbonyls which represent oxidative modification of DNA and proteins were completely reversed by 6-gingerol. This was further endorsed by restored superoxide dismutase and catalase activities with 6-gingerol against alcohol-induced loss. The elevated cardiac biomarkers (CK-MB, cTn-T, cTn-I) and dyslipidemia in alcohol-intoxicated rats was significantly reversed by 6-gingerol. Furthermore, alcohol-induced apoptosis characterized by overexpression of cytochrome C, caspase-8 and caspase-9 was diminished with 6-gingerol treatment. Transmission electron microscope images conferred the cardioprotective properties of 6-gingerol as we have seen less structural derangements in mitochondria and reappearance of myofilaments. Our findings conclude that 6-ginger effectively protect alcohol-induced ROS-mediated cardiac tissue damage, which may be due to its potent antioxidant efficacy. Therefore, 6-gingerol could be a potential therapeutic molecule that can be used in the treatment of alcohol-induced myocardial injury.
Background: A highly valued medicinal plant belonging to the family Apiaceae is Trachyspermum ammi L. The seeds of this plant are used as spice and are traditionally used for the treatment of many human and animal illnesses. Objectives: In this research study, we aimed at quantitatively estimating the phytochemicals, antioxidant and antimicrobial activity of different solvent extracts of T. ammi seeds. Methods: Quantification of phenol and flavonoid phytochemicals have been estimated in different solvent extracts of seeds. Further, the antioxidant activity was determined by performing DPPH, lipid peroxidation, reducing capacity and total antioxidant activity assays. Additionally, antibacterial activity was assessed against three bacterial species using well-diffusion method. Results: The findings showed in quantitative estimation that phenols and flavonoids were rich in extracts. Acetone, Methanol and Ethanol extracts were potentially scavenged DPPH radical, lipid peroxidation nullified and metal ions such as Fe and Mo reduced. At the same time, effective antibacterial activity on E. coli, S. aureus and Pseudomonas bacterial species was seen in Chloroform and Methanol extracts and synthesized silver nanoparticles. Conclusion: In conclusion, free radical scavenging, reduction of metals and antibacterial activity of different extracts of T. ammi was indicative of the presence of enormous amounts of phenols and flavonoids. Further work on these extracts needs to be done to isolate the active compounds and, to treat free radicals and related bacterial diseases.
In our in vitro and in vivo studies, we used Acalypha indica root methanolic extract (AIRME), and investigated their free radical scavenging/antioxidant and anti-inflammatory properties. Primarily, phytochemical analysis showed rich content of phenols (70.92 mg of gallic acid/g) and flavonoids (16.01 mg of rutin/g) in AIRME. We then performed HR-LC-MS and GC-MS analyses, and identified 101 and 14 phytochemical compounds, respectively. Among them, ramipril glucuronide (1.563%), antimycin A (1.324%), swietenine (1.134%), quinone (1.152%), oxprenolol (1.118%), choline (0.847%), bumetanide (0.847%) and fenofibrate (0.711%) are the predominant phytomolecules. Evidence from in vitro studies revealed that AIRME scavenges DPPH and hydroxyl radicals in a concentration dependent manner (10–50 μg/mL). Similarly, hydrogen peroxide and lipid peroxidation were also remarkably inhibited by AIRME as concentration increases (20–100 μg/mL). In vitro antioxidant activity of AIRME was comparable to ascorbic acid treatment. For in vivo studies, carrageenan (1%, sub-plantar) was injected to rats to induce localized inflammation. Acute inflammation was represented by paw-edema, and significantly elevated (p < 0.05) WBC, platelets and C-reactive protein (CRP). However, AIRME pretreatment (150/300 mg/kg bodyweight) significantly (p < 0.05) decreased edema volume. This was accompanied by a significant (p < 0.05) reduction of WBC, platelets and CRP with both doses of AIRME. The decreased activities of superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase in paw tissue were restored (p < 0.05 / p < 0.01) with AIRME in a dose-dependent manner. Furthermore, AIRME attenuated carrageenan-induced neutrophil infiltrations and vascular dilation in paw tissue. For the first time, our findings demonstrated the potent antioxidant and anti-inflammatory properties of AIRME, which could be considered to develop novel anti-inflammatory drugs.
Acalypha indica is a significant medicinal plant. The purpose of this review is to bring traditional usage, phytochemistry, and scientific applications of A. indica up to date. Microbial infections, fertility, stomach ulcers, snake bites, pains, wounds, liver/kidney problems, and rheumatism have all been traditionally treated with A. indica paste, decoction, sap, and synergy with other plants/plant products, which have all been scientifically proven through in vitro and in vivo experiments. Regardless of traditional knowledge, this plant extracts have been scientifically proven to help against cancer, inflammation, cardiac damage, diabetes, TB, and malaria. Phytochemical investigation revealed that A. indica has phenols, flavonoids, tannins, coumarins, alkaloids and their glycosides, saponins, volatiles and fatty acids. In summary, the presence of phytoconstituents is responsible for the A. indica traditional and pharmacological qualities. Further, conformational clinical trails in humans are necessary to ascertain the extracts efficacy. Extensive future studies are to be conducted to reveal the mechanism of action, pharmacokinetic properties and active phythochemicals of A. indica extracts.

The present engineering applications require new and better materials for the replacement of existing ones. In view of this demand, at present we focused on latest upcoming materials such as composite materials especially laminated composites. The composites are having the greatest strength to weight ratio compared to conventional materials. Fiber reinforced polymer composites have been used in a variety of application because of their many advantages such as relatively low cost of production, easy to fabricate and superior strength compare to neat polymer resins. Reinforcement in polymer is either synthetic or natural. Synthetic fibers such as glass, carbon etc. have high specific strength but their fields of application are limited due to higher cost of production. The present research focus on characterization and testing of Biwoven Glass Fiber/Epoxy composite material. The different mechanical tests are performed on Bi-wove Glass Fiber/Epoxy composite and the mechanical properties such as, tensile strength, tensile modulus, compressive strength is determined as per ASTM standards. The mechanical properties were improved as the number of layers of Bi-woven glass fibers reinforcement content increased in the epoxy matrix material
Background: The prevalence of diabetes in the world population hás reached 8.8 % and is expected to rise to 10.4% by 2040. Hence, there is an urgent need for the discovery of drugs against therapeutic targets to sojourn its prevalence. Previous studies proved that NF-κB serves as a central agent in the development of diabetic complications. Objectives: This review intended to list the natural plant compounds that would act as inhibitors of NF-κB signalling in different organs under the diabetic condition with their possible mechanism of action. Methods: Information on NF-κB, diabetes, natural products, and relation in between them, was gathered from scientific literature databases such as Pubmed, Medline, Google scholar, Science Direct, Springer, Wiley online library. Results and Conclusion: NF-κB plays a crucial role in the development of diabetic complications because of its link in the expression of genes that are responsible for organs damage such as kidney, brain, eye, liver, heart, muscle, endothelium, adipose tissue and pancreas by inflammation, apoptosis and oxidative stress. Activation of PPAR-α, SIRT3/1, and FXR through many cascades by plant compounds such as terpenoids, iridoids, flavonoids, alkaloids, phenols, tannins, carbohydrates, and phytocannabinoids recovers diabetic complications. These compounds also exhibit the prevention of NF-κB translocation into the nucleus by inhibiting NF-κB activators, such as VEGFR, RAGE and TLR4 receptors, which in turn, prevent the activation of many genes involved in tissue damage. Current knowledge on the treatment of diabetes by targeting NF-κB is limited, so future studies would enlighten accordingly.

Results: The result showed that PLF was significantly decreased the blood glucose levels, liver biomarkers such as AST, ALT, ALP, bilirubin content, lipid profiles like LDL, TC, and TGs and decreased the tissue damage in diabetic rats. Subsequently, insulin, body weight, and HDL levels were increased in diabetic rats. Subsequently, insulin, body weight, and HDL levels were increased. Conclusion: We concluded that Ai (Acalypha indica ) leaves have a rich number of polyphenolic compounds and those were may be protected from STZ-induced toxicity in liver of diabetic rats. Further research is necessary for this area to isolate bioactive polyphenolic compounds from Ai leaves and to be validated against STZ-intoxicated liver damage with assessing mechanism of action.

The free radicals are generated in normal cellular metabolic events .However they may be produced more in disease conditions when they directly interact with the bio molecules are dangerous to the normal life because they alter genetic material. Free radicals induce permanent modifications in genetic material that may lead to mutagenesis, carcinogenesis and aging. The prevention or treatment of diseases has direct link with antioxidants which can reduce the effect of free radicals. The phenolic compounds are functionally potent antioxidants and they have the ability to scavenge reactive oxygen species (ROS)/ reactive nitrogen species(RNS), suppress the ROS/RNS formation by inhibiting relevant enzymes, chelates trace metal elements responsible for free radical generation and up regulates or protects the antioxidant defense system. In this study, we attempted for the separation of Polyphenolic fraction from Acalypha indica leaves and tested for its antioxidant activity employing DPPH, H2O2 assays and also to assess its reducing power, total antioxidant power. The outcome of the results from this study showed that Polyphenolic fraction from the Acalypha indica leaves scavenges the in vitro free radicals to their stable forms such as DPPH radical to DPPH, Mo (VI) to Mo (V), ferric cyanide complex to ferrous form and hydrogen peroxide to water. The polyphenolic fraction has the reduction power against free radicals which suggests further studies to take up in in vivo for the treatment of various diseases due to free radicals generation.
Antioxidant defense system plays a key role in diabetic complications. The effects of ginger ethanolic extract on ruined antioxidant system in liver tissue remains unclear in diabetic rats. In this study, we investigated the impact of oral administration of ginger ethanolic extract on antioxidant parameters in experimental diabetic rats. Thirty rats were equally divided into five groups, including normal control (NC), diabetic control (DC), ginger treatment (Gt), diabetics treated with ginger (D+ Gt) and diabetics treated with glibenclamide (D+ Glb). The parameters like SOD, CAT, GPx, GR, GST activities and GSH levels were significantly decreased in liver of diabetic rats, which indicates impaired antioxidant status. The lipid peroxidation marker MDA levels were drastically increased in diabetic rats. However, we found that the administration of ginger to diabetic rats restored the altered antioxidant status that is almost similar to normal control group, simultaneously depleted MDA levels in liver of diabetic rats. Further, evidences from our histopathological studies also prove that ginger protects the liver from oxidative stress in diabetic rats.
