Neuroprotective Effect of Cinamomum zeylanicum in streptozotocin induced diabetes in Mice
Get PDFBackground: Diabetes is recognized as one of the leading causes of morbidity and mortality and representing as an emerging global epidemic worldwide. Diabetes and stroke both are the conditions which share various common threats. A patient with Diabetes has higher risk of stroke as compared to non Diabetics. Diabetes and stroke both affects the blood vessels. There are several biochemical pathways which are responsible for the developments of vascular complications due to hyperglycemia. Thus prevention and treatment of diabetes and stroke can reduce the risk of various vascular diseases. Cinnamomum zeylanicum has been used for the treatment of diabetes since long time. Cinnamomum zeylanicum rich in phenolic contents (antioxidants) have been identified as a major active component exhibiting antioxidant, and neuroprotective effects. The present study evaluate the neuroprotective effect of Cinnamomum zeylanicum in streptozotocin induced diabetes in mice and experimentally induced global cerebral ischemia/reperfusion injury in mice. Materials and methods: Swiss albino mice (male) weighing 20-30 g were randomized into eight groups. Diabetes was induced by administering streptozotocin (65 mg/kg, i.p).Starting from seven days after streptozotocin injection, insulin and Cinnamomum zeylanicum were administered for 3 weeks. Serum glucose level and body weight were measured weekly. Neuroprotective activity was carried out by global cerebral ischemia on swiss albino mice by carotid artery occlusion for 10 min followed by 24 hr. reperfusion. Measurement of Triglycerides, Malondialdehyde , cerebral infarct size and glutathione level was carried out at the end of the study. Results: After 21 days of treatment with Cinnamomum zeylanicum (75 mg/kg, 150 mg/kg and 300 mg/kg, p.o) significant increase in body weight and glutathione level and a significant reduction in serum glucose level, triglycerides, MDA levels and cerebral infarct size was observed as compared to diabetic control and diabetic+ stroke group. Conclusion: The present study concludes that Polyphenolic fraction of Cinnamomum zeylanicum not only attenuates the diabetes but also reverse the cerebral infarction in mice through its neuroprotective actions and thus Cinnamomum zeylanicum may serves as a new therapeutic alternative for management of brain damage associated with type-1 diabetes

Association of altered serum levels of Chemerin, Paraoxonase-1 (PON1), Asymmetric Dimethyl arginine (ADMA) and obesitin the development of Polycystic Ovarian Syndrome (PCOS) in Egyptian women
Get PDFChemerinwas recently added to the adipokine family and was identified in human ovarian follicles and follicular fluid that suggests a direct correlation between chemerin and PCOS. Asymmetric dimethyl arginine (ADMA) is involved in endothelial dysfunctionthe atherogenic potential of ADMA has been investigated in young patients with PCOS. Oxidative stress is considered to be implicated in the pathophysiology of PCOS.Paraoxonase 1 (PON1) is an antioxidant enzyme and its concentration has been shown to be inversely associated with oxidative stress. Objectives: Evaluation of serum chemerin, ADMA, PON1in obese and non-obese polycystic ovarian patients to postulate their role in pathogenesis of PCOS. Methods: Ninetynuligravida women aged 20-35 (60 with PCOS and 30 controls) were recruited. Fasting blood was obtained on day 2 or 3 of the menstrual cycle. Clinical evaluation, hormonal profile, Chemerin, ADMA and PON1 were assessed. Results: There was a significant increase in serum chemerinlevels in PCOS obese group when compared with PCOS non obese patients and healthy controls non obese and obese respectively. Serum ADMA level was increased significantly in PCOS obese group as compared to the PCOS non obese group , control non obese and control obese. Paraoxonase was decreased stepwise significantly from the control non obese group and control obese group to PCOS non obese patients then PCOS obese patients to. Conclusions: it could be suggested that increased chemerin has a role in PCOS development andaltered ADMA and PON1 associated withobesity and oxidative stress may exacerbate the condition
