DL alpha-lipoic acid has been shown to prevent the induced precipitation of calcium oxalate crystals in the renal tissues of laboratory animals. The acid seems to have a profound influence on carbohydrate metabolism in diabetic rats. Here the effect of alpha-lipoic acid was studied on certain key carbohydrate metabolising enzymes in the tissues of calcium oxalate stone forming rats administered with glycollate as oxalate precursor. There was augmentation of glycolysis in the renal tissues of stone forming as well as lipoate administered rats. The two major gluconeogenic enzymes, glucose-6-phosphatase (G6P) and fructose-1, 6 diphosphatase (FDP) were significantly inhibited in tissues of calculogenic rats. Lipoic acid also reduced the enzyme activities significantly. The citric acid cycle enzymes were not influenced to an appreciable extent. The observed alterations are likely to be due to the regulatory effects of oxalate and lipoate on the enzyme systems.

The effect of DL alpha-lipoic acid on the nephrotoxic potential of gentamicin was examined. Intraperitoneal injection of gentamicin (100 mg/kg/day) to rats resulted in decreased activity of the glycolytic enzymes-hexokinase, phosphoglucoisomerase, aldolase and lactate dehydrogenase. The two gluconeogenic enzymes--glucose-6-phosphatase and fructose-1,6-diphosphatase, the transmembrane enzymes namely the Na+, K(+)-ATPase, Ca(2+)-ATPase, Mg(2+)-ATPase and the brushborder enzyme alkaline phosphatase, also showed decreased activities. This decrease in the activities of ATPases and alkaline phosphatase suggests basolateral and brush border membrane damage. Decreased activity of the TCA cycle enzymes isocitrate dehydrogenase (ICDH), succinate dehydrogenase (SDH) and malate dehydrogenase (MDH), suggests a loss in mitochondrial integrity. These biochemical disturbances were effectively counteracted by lipoic acid administration. Lipoic acid administration by gastric intubation at two different concentrations (10 mg and 25 mg/kg/day) brought about an increase in the activity of the glycolytic enzymes, ATPases and the TCA cycle enzymes. The gluconeogenic enzymes however showed a further decrease in their activities at both the concentrations of lipoic acid administered. These observations shed light on the nephroprotective action of lipoic acid against experimental aminoglycoside toxicity and the protection afforded at 25 mg/kg/day of lipoic acid was noted to be higher than that at 10 mg level.
