Ultrastructural changes in the developing chicken cornea following caffeine administration.
Caffeine is one of the most frequently consumed psychoactive substances. It has been known for many years that caffeine at high concentrations exerts harmful effects on both women's and laboratory animals' fertility, moreover it may impair normal development of many organs in the prenatal period. So far there have been few studies performed that demonstrate teratogenic effects of caffeine on st...
متن کاملThe Ultrastructural Changes of the Sertoli and Leydig Cells Following Streptozotocin Induced Diabetes
Objective(s) This investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue. Materials and Methods Diabetes was induced in male adult rats by a single intraperitoneal injection of streptozotocin. Body and testicular weight, hormonal analyses, histological and ultrastructural analyses were measured. Results The body and testicular we...
متن کاملUltrastructural changes in the retinopathy, globe enlarged (rge) chick cornea☆
In the cornea, the precise organisation of fibrillar collagen and associated proteoglycans comprising the stromal extracellular matrix plays a major role in governing tissue form and function. Recently, abnormal collagen alignment was noted in the misshapen corneas of mature chickens affected by the retinopathy, globe enlarged (rge) mutation. Here we further characterize corneal ultrastructural...
متن کاملThe Effect of Diazoxide on Ultrastructural Changes Following Ischemia-Reperfusion Injury of Rat Brain
A B S T R A C T Introduction: Even today there is no effective drug therapy to prevent neuronal loss after brain stroke. In the present study we studied the effect of mitochondrial KATP channel regulators on neuronal ultrastructure after ischemia reperfusion in the rat. Materials & Methods: Rats temporarily subjected to four vessels occlusion for 15 minutes followed by 24 hours reperfusion with...
متن کاملAcute ultrastructural changes of cornea after excimer laser ablation.
Corneal ultrastructural changes induced by an argon fluoride excimer laser using different parameters were investigated. Twenty-eight rabbit corneas were ablated at light doses per pulse and repetition rates ranging from 25-800 mJ/cm2 and 1-100 Hz, respectively, at four different total light doses (25-150 J/cm2). Transmission electron microscopy showed that corneal ablations done at subthreshol...
