ABSTRACT
Present study was undertaken to study the neurotoxicity of oral acrylamide (ACR) and its amelioration using α-tocopherol, reduced glutathione (GSH) and hot aqueous extract (HAE) of Ocimum sanctum. Forty five male Wistar rats were divided into 12 groups. The study showed a significant reduction in the body weight of the rats fed with ACR in comparison to the other groups while body weight was restored in the rats fed with α-tocopherol and HAE. Neurotoxicity in rats fed with ACR was evident with the results of histopathology and oxidative stress (high MDA and decreased activities of GSH, SOD, GST and CAT in brain). Co-administration of α-tocopherol and HAE lowered these changes however, there was no marked improvement seen in neural damage but improvement was evident in behavioral as well as physiological changes at a marked point. Histopathology of brain in ACR alone fed group showed extensive neural degeneration and massive deposition of fibrin which was substantially decreased and ameliorated with the co-administration of α-tocopherol and HAE. These results support the oxidative stress results as well. Our results suggests that α-tocopherol and HAE can be useful for protecting brain tissue against ACR induced neurotoxicity through minimizing the free radical mediated oxidative stress
ABSTRACT
Spermatozoa undergoes array of signaling and intracellular pathways and ultimately become competent enough to accomplish fertilization. Hormones, ion channels and signaling molecules in both male and female reproductive tract show bidirectional cross play. The recent discovery of endocannabinoids and their receptors in male and female reproductive system opened new vistas for their research in regulating sperm function. Interestingly, endocannabinoids regulate sperm motility, capacitation, hyperactivity and eventually acrosome reaction. However, their complex intracellular pathways are still to be understood in regulating spermatozoa function. The present review highlights the major breakthrough research in the area of endocannabinoids in male reproduction and in more specific in sperm cells, and their association with regulation of sperm fertilizing competence
