Rickettsia rickettsii infection of endothelial cells is manifested in very distinctive changes in cell morphology, consisting of extensive dilatation of the membranes of the endoplasmic reticulum and outer nuclear envelope and blebbing of the plasma membrane, as seen by transmission electron microscopy (D. J. Silverman, Infect. Immun. 44:545-553, 1984). These changes in cellular architecture ar...

Ascorbic acid recycling from dehydroascorbic acid and biosynthesis from gulono-1,4-lactone were used as measures of cellular response capacity to increased oxidative stress induced by tert-butylhydroperoxide. The hepatic ascorbic acid concentration was 54% lower in cells from old rats when compared to cells isolated from young rats (P<0.0005). Freshly isolated hepatocytes from old rats exhibite...

Lead (Pb) is known to negatively affect glutathione (GSH) metabolism in the lens. The present study examined the effects of Captopril, Taurine, and alpha-Lipoic acid on the Pb-induced GSH depletion and lipid peroxide increase in the lenticular system. Captopril administration returned the GSH, cysteine (CYS), and malondialdehyde (MDA) levels to near normal. Following Taurine administration the ...

INTRODUCTION Diabetes mellitus is a metabolic, chronic and incurable disease which reduces span and quality of life. Over 50% of diabetic patients have clinical manifestations of diabetic neuropathy. AIM To show a positive influence of alpha lipoic acid on clinically manifested diabetic neuropathy symptoms as well as the effect of alpha lipoic acid in patients glycaemic control. MATERIAL AN...
