Abstract:
:Troglitazone (T) and d-chiroinositol (DCI) have been reported to improve insulin resistance associated with obesity and NIDDM. We tested whether these compounds counteract the insulin antagonistic effects of recombinant human GH. Male Wistar rats were allocated to 4 different treatment groups, rhGH (n=8), rhGH+T (n=7), rhGH+DCI (n=8) and control (saline, n=8). rhGH (2 IU/100 g/day) was injected sc twice daily for 2 days. T and DCI were given (20 mg/day) po for 5 days preceding and 2 days along with rhGH. Euglycemic hyperinsulinemic clamp studies were done to assess the hepatic glucose output (HGO) and glucose disappearance rate (GDR). Fasting plasma glucose, insulin, serum FFA and basal HGO were similar in all 4 treatment groups. During the hyperinsulinemic clamp which raised plasma insulin levels to 7.2 +/- 0.4 ng/ml, HGO was suppressed in the control and rhGH+T treated rats but not in the rats treated with rhGH and rhGH+DCI. GDR decreased in the rats which received rhGH (18.1 +/- 5.8 vs 30.3 +/- 5.2 mg/kg/min) compared to the control rats. The rats given either T (24.7 +/- 2.7) or DCI (31.4 +/- 2.7) along with rhGH showed comparable GDR to the control rats. These results indicated that rhGH induced hepatic and peripheral insulin resistance. Troglitazone counteracted the insulin-antagonistic action of rhGH both in the liver and the peripheral tissues. DCI was effective in offsetting peripheral insulin resistance but without any effect on hepatic insulin resistance associated with rhGH treatment.
