Diabetes decreases the fertility of females, but the mechanisms are not completely understood. In our investigations, we have found that 13% of the female BB Wistar rats that spontaneously developed chemical diabetes had persistent estrous. In this study the ovaries of these rats were examined by scanning electron microscopy(SEM) and compared to normal-cycling controls as well as to rats that had developed polycystic ovaries(PCO) by exposure to constant 1ight.

The ultrastructure of neurosecretory cells and glia cells in the supraoptic nucleus (SON) of the hypothalamus and the neurohypophysis (PN) was studied after rapid freezing followed by substituion fixation. Also, the ultrastructural localization of vasopressin (VP) or its carrier protein neurophys in II (NPII) in the SON and PN was demonstrated by using a post-embedding immunoco1loidal gold staining method on the tissue sections processed by rapid freezing and freeze-substitution fixation.Adult male Wistar rat hypothalamus and pituitary gland were quenched by smashing against a copper block surface precooled with liquid helium and freeze-substituted in 3% osmium tetroxide-acetone solutions kept at -80°C for 36-48h. After substituion fixation, the tissue blocks were warmed up to room temperature, washed in acetone and then embedded in an Epon-Araldite mixture. Ultrathin sections mounted on 200 mesh nickel grids were immersed in saturated sodium metaperiodate and then incubated in each of the following solutions: 1 % egg albumin in phosphate buffer, VP or NPII (1/1000-1/5000) antiserum 24h at 4°C, 3) colloidal gold solution (1/20) 1h at 20°C. The sections were washed with distilled waterand dried, then stained with uranylacetate and lead citrate and examined with Hitachi HU-12A and H-800 electron microscopes.

Background: Most stroke survivors live with residual physical impairments that may promote a sedentary lifestyle and resultant secondary complications, especially poor cardio-respiratory fitness. This systematic review was conceived to examine the extent of research on the effect of aerobic exercise on health outcomes of stroke survivors as a prelude to a clinical trial.Method: Electronic databases were searched with the last search performed in May, 2014. The methodological quality of studies was assessed using the PEDro scale. High-quality randomized controlled trials (RCTs) were considered level 1 evidence while lower-quality RCTs were considered level 2 evidence. Result: A total of 642 articles were generated from the search strategy; 10 articles fulfilled all criteria and were selected for this review. 50% of these studies recruited stroke survivors with ischaemic type of stroke while 30% had individuals with either ischaemic or haemorrhagic types. 70% of the studies had good scores while 30% had fair scores in methodological quality. The majority of the studies used VO2max as the outcome for assessing aerobic fitness; a few studies (10% each) assessed anthropometric outcomes and biochemical profile. No study assessed a haematological profile nor compared the effects of continuous and interval aerobic exercise on stroke outcomes. Conclusion: A gap in clinical trials on the effects of aerobic exercise on biochemical, haematological and anthropometric profiles of stroke survivors exists as well as in the comparative effects of continuous and interval training on stroke outcomes.
