cloned and characterized from mammalian tissues, the seven transmembrane G protein-coupled cannabinoid receptors type 1 (CB1 receptor), [5] and type 2 (CB2 receptor) [6]. Whereas the CB1 receptor expression is abundant in the central nervous system, the CB2 receptor is almost exclusively expressed in the immune system. The CB1 receptor is also expressed in peripheral nerve terminals and various extraneuronal sites such as the testis, uterus, eye, vascular endothelial, spleen and adipocytes [7-10]. Pharmacological evidence exists for the presence of other cannabinoid receptors, which, however, have not yet been cloned [11]. The cannabinoids are found to have particular application as neuroprotectants for mental and motor dysfuction in neurodegenerative diseases. The neuroprotective properties of cannabinoids suggest their therapeutic use for limiting neurological damage. The cannabinoids treatments should not only aim to alleviate specific symptoms but also attempt to delay/arrest disease progression and to repair the damaged structures. The author conducted a review of studies published between 1974 and 2011. The search was performed using the following PubMed search terms: “Cannabinoids” and “Neurodegenerative Diseases” and 287 papers were detected. The articles were examined, and the overlapping or insufficiently clear works were excluded. Finally, we chose 117 articles regarding the latest international guidelines, the pathophysiology of neurodegenerative diseases and the various therapeutic choices. The studies reported in the present review support the view that the cannabinoid signalling system is a key modulatory element in the activity of the basal ganglia. This idea is supported by different anatomical, electrophysiological, pharmacological and biochemical data. Furthermore, these studies indicate that the cannabinoid system is impaired in different neurological disorders that directly or indirectly affect the basal ganglia, which supports the idea of developing novel pharmacotherapies with compounds that selectively target specific elements of the cannabinoid system. Abstract
Medications are powerful tools that, if used correctly, can prevent or treat disease. If used incorrectly, there is potential to cause great harm to people who take them. These unintended effects, called adverse effects, can occur from any medication. As health care teams, which include physicians, pharmacists, and other health care providers, are making decisions about using specific medications to treat an individual patient, they must weigh the potential risks against the desired benefit of each medication to minimize the chance of harm to the patient.
Pharmacovigilance is the science and exercises related with social affair, acknowledgment, evaluation, checking, and balancing activity of untoward contacts with pharmaceutical things. Pharmacovigilance basically sheets wellbeing of medicine. Pharmacists have enter jobs in prosperity frameworks to guard up the sensible and use of medicine for they are cure authorities who are unequivocally arranged in this field. The viewpoint of drug store understudies on pharmacovigilance and ADR uncovering has also been analyzed with an expect to focus the need to enhance content related to ADR declaring and pharmacovigilance in student drug store instructive projects. All inclusive, in spite of the way that the activity of pharmacists inside national pharmacovigilance frameworks contrasts, it is particularly all around seen. Compromise of ADR declaring thoughts in guidance instructive modules, getting ready of pharmacists and intentional duty of pharmacists in ADR uncovering is basic in achieving the security targets and conservation of general prosperity. In like manner, these learning openings can be pacified through relentless master enhancement extends and invigorating theoretical and sensible data in student drug store instructive projects. Without satisfactorily recognizing and recognizing getting ready necessities of pharmacists and other human administrations specialists, the ability of national pharmacovigilance frameworks is likely not going to upgrade which may exchange off patient's wellbeing. Keywords: Prevention, Monitoring, Pharmacists, ADR, Safety, Medicine.
A New, simple and sensitive spectrophotometric method for the determination of Metronidazole (MN) has been developed. The method is based on reduction of nitro group of MN to amine group by Zn dust and concentrated hydrochloric acid in hot ethanol under stirring, then the diazonium ion was prepared and coupled with para hydroxyl benzaldehyde (p-HB) to yield Insoluble water yellow dye indicated at 410nm. The linearity of the method was between 5.8×10 -5 M-52.2×10 -5 M, the molar absorptivity was 7131.121 L.mol -1 .cm -1 and Sandell index was 0.0240µg.cm -2 . The method has been successfully applied to the assay of MN in pure and pharmaceutical forms.
The pharmacodynamic effect of ceftriaxone on smooth muscles was investigated in isolated organs. Maximum stimulation of isolated guinea pig's ileum, rabbit's duodenum and rat's fundic strip was achieved by addition of 1024 mu g of ceftriaxone/ml bath. While in isolated rat's colon, it was achieved by 512 mu g of ceftriaxone/ml bath. The effect of graded increased concentrations of ceftriaxone on isolated tracheal muscles and rat's uterine muscles was examined during estrus, non estrus, early pregnant and late pregnant stages. Trials were performed to locate the site of action of ceftriaxone on isolated smooth muscles. It was concluded that, ceftriaxone directly stimulates the smooth muscles of intestines; ceftriaxone in concentration of 1024 mu g/ml bath has a serotonin like effect on rat's fundic strip and had a direct myometrial depressant effect. Ceftriaxone in all tested concentrations did not induce any effects on the resting tonus of isolated guinea pig's tracheal chain.
