BACKGROUND
Insulin resistance is a risk factor for cardiovascular disease and type 2 diabetes mellitus. There are many previous studies indicating that insulin lowers serum sex hormone-binding globulin levels, and there is inverse correlation between insulin resistance and serum sex hormone-binding globulin levels in women. However, in men, a limited number of studies are available to explain the effect of sex hormone on age and insulin. Therefore, the present study was undertaken to investigate the relationship among free testosterone, hormone- binding globulin and age in type 2 diabetic men and control subjects. METHOD: Age, body mass index, total cholesterol, triglyceride, fasting blood sugar, and insulin concentrations were examined on 89 type 2 diabetic men and 47 control subjects. The free testosterone level was measured by commercially available double-antibody system (Radioimmunoassay). The sex hormone-binding globulin level was also measured by commercially available double-antibody system(Immunoradiometric assay). RESULTS: 1) Sex hormone-binding globulin level was significantly increased in patients with type 2 diabetes. However, there was no significant difference in free testosterone level between the two groups. 2) Sex hormone-binding globulin was positively correlated with age (r=0.4, p<0.001) in patients with type 2 diabetes. Sex hormone-binding globulin and free testos terone were not correlated with age in control sujects. 3) Free testosterone and sex hormone-binding globulin concentrations were not significantly related to serum insulin concentration after adjusting for age and body mass index. CONCLUSIONS: We observed increased sex hormone-binding globulin concentration in diabetes man, and was a positively related to age. Further studies are needed to understand the relationships between age, insulin resistance, testosterone, and sex hormone-binding globulin concentrations.

BACKGROUND
It is sometimes very difficult to control the elevation of postprandial glucose with diet therapy only in patients with NIDDM partly because of their defective insulin response to glucose. Recently the alpha-glucosidase inhibitors which inhibit carbohydrate digestion and suppress or delay absorption of the final breakdown products, glucose and fructose when it is taken orally with meal have been widely used in the treatment of diabetes. The drugs, however, provoke the adverse effects e.g. flatulence, diarrhea etc. in some patients. Therefore we studied the efficacy of the more recently developed alpha glucosidase inhibitor, Voglibose (Basen, Cheiljedang) METHODS: Fifty five patients whose postprandial two hour serum glucose levels were more than 11.1 mmol/L despite the strict diet therapy during the 4 week observation period were assigned to receive Voglibose 0.2 mg before each meal t.i.d. for 8 weeks. Of 55 subjects, 41 were given Voglibose 0.3 mg t..i.d. for the last 4 weeks because of their poor glucose control, RESULTS: The postprandial one and two hour serum glucose levels significantly decreased after therapy; 1 hour: 17.5+4.4 mmol/L(prior to therapy), 15.4+3.8 mmol/L(4 week after), 14.8+5.1 mmol/L(8 week), p <0.00l, 2 hour: 16.7+4.5 mmol/L, 14.8+3.9 mmol/ L, 14.8+4.5 mmol/L, p<0.00 l, t-tests for paired samples. Total serum cholesterol and HDL cholesterol levels also significantly decreased(5.24+1.06 - 4.90+1.27 mmol/L, p=0.036, 1.34+0.66 1.16 +0.3l mmol/L, p=0.035 respectively) However, HbAlc, serum fructosamine, insulin and triglyceride levels were not significantly changed. The prevalence of the adverse effects due to Voglibose was 14%(10/71). All of them were less than grade II of WHO criteria and disappeared despite continuing therapy. CONCLUSION: Voglibose monotherapy is considered as having an glucose lowering effect in patients with NIDDM whose adequate postprandial blood glucose cannot be achieved with diet therapy only.
