Abstract: | The effect of a long-acting somatostatin analogue on the acute renal hypertrophy following induction of experimental diabetes in the rat has been studied. The kidney weight increase occurring at 2 and 7 days after alloxan injection was significantly lower in the diabetic group receiving somatostatin. Similarly, the previously reported increase in glucose-6-phosphate dehydrogenase (EC 1.1.1.49) and 6-phosphogluconate dehydrogenase (EC 1.1.1.44) found in the kidney at 2 and 7 days of diabetes was less marked in the group receiving SMS 201-995. The fall in renal phosphoribosyl pyrophosphate associated with early diabetic renal hypertrophy (7) was also lessened by administration of SMS 201-995. No effects of the drug were found in the normal rat on the same regimen of treatment. These observations indicate involvement of glucagon and/or growth hormone in the initiation of kidney growth in diabetes. |
