Resumen

CORREA, Lanna Beatriz Neves Silva et al. Influence of Alpha Lipoic Acid Supplementation on Urinary Bladder Morphology of Diabetic Rats. Int. J. Morphol. [online]. 2020, vol.38, n.3, pp.627-633. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022020000300627.

Diabetes Mellitus (DM) is a condition marked by hyperglycaemia that causes systemic complications, including urinary vesicle dysfunction due to oxidative stress. Further, antioxidants, as well as alpha lipoic acid (ALA), may be a response to this pathological condition. The present study verified the action of ALA as a supplement in ration on glycemia and urinary vesicle structures of rats induced by streptozotocin. The rats were divided into 4 groups: Control (CG), Alpha Lipoic (ALAG), Diabetic control (DCG), and the Diabetic alpha lipoic (DALAG) group. For induction, the diabetic groups were initially induced with streptozotocin (dose 60 mg/kg). Subsequently, group glycemia was evaluated weekly. After 8 weeks, the rats were euthanized and the bladder was collected. The bladders were histologically processed and the slides were stained with Masson’s Trichrome for the histomorphometry of epithelial height, connective and muscular tissue and coloration of PicroSirius Red for further analysis of collagen fibers of the bladder. The data of the glycemia demonstrated an inferior median in DALAG compared to DGC (p<0.01). The epithelial height and percentage of the muscle tissue were greater in DALAG compared to the DGC, but not significant. However, GDAL showed improvement in the organization of collagen fibers. In conclusion, bladder the morphology alterations caused by DM were not alleviated by the administration of ALA in 8 weeks of the experiments.
