: Bilateral cryptorchidism was induced surgically in adult wistar strain albino rats and the carbohydrate metabolic pathway has been studied in testis, and sex accessory organs of both control and cryptorchid animals by estimating the marker enzymes and the substrates of the metabolism. In cryptorchid animal tissues, accumulation of lactic acid and glycogen was observed with inhibited phosphorylase activity in comparison to the controls. The reproductive tissues like testis, epididymis, prostate gland and seminal vesicles had shown remarkable elevation in the glycogen content, which can be attributed to decreased phosphorylase activity. In view of androgen dependent nature of phosphorylase its inhibition can be correlated to decreased testosterone circulation in the body. Consequently the free glucose content of the tissues was markedly decreased suggesting a decrease in the mobilization of the carbohydrates into energy metabolism. All the reproductive tissues had shown significant accumulation of lactic acid with inhibited oxidative enzyme activities. Thus the reproductive tissue oxidative metabolism had been suppressed during cryptorchidism leading to a shift towards glycolysis and creating a situation of functional suppression.
Abstract:The effect of adrenelectomy was studied on the antioxidant metabolism in different tissues (Liver, heart, kidney and muscle) of rat. G-6-PDH was increased significantly in liver and heart and the same was decreased in kidney with a non significant change in muscle. SOD was significantly increased in heart and muscle. Catalase was significantly decreased in liver and muscle and was increased significantly in kidney. XOD showed significant decrease in liver and increase in heart, kidney and muscle. The present finding, in general, exhibit tissue specific alterations in free radical metabolism in conjunction with antioxidant defence mechanisms during adrenal hormone deficiency. It is also clear from the results that the mechanisms involved in selective activation / inhibition of different pathways seems to reflect multifaceted physiological adaptations as a compensatory measure during induced adrenalectomy.
Bilateral cryptorchidism was induced surgically in adult wistar strain male albino rats and lipid fractions such as total lipids, total cholesterol, Free cholesterol, Esterified cholesterol, phospholipids, Triglycerides and free fatty acids were analysed in the plasma, heart and dorsal aorta. The lipid fractions such as triglycerides (56.63%), free (20.82%) and esterified (61.25%) cholesterol as well as fatty acids in glycerol (64.42%) had significant elevation in the plasma of cryptorchid animals. Similarly LDL lipid fractions (64.99%) were also elevated markedly under cryptorchid conditions which are the markers of the obesity and atherosclerosis. The lipid fractions such as triglycerides (50.47%, 48.17%), cholesterol (74.64%, 67.7%) and phospholipids (42.04%, 68.88%) showed significant elevations in the heart and dorsal aorta of the cryptorchid animals over the control. The heart, dorsal aorta and plasma had significant accumulation of triglycerides and cholesterol fractions, suggesting the possible deposition of lipid fractions in the tissues, which can be attributed to the possible suppression in the mobilization of lipid fractions into energy metabolism. Such an accumulation of lipid fractions under cryptorchid condition can be considered as the development of risk factor for the cardio-vascular disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
