Abstract:
This study evaluates the effect on high-density lipoprotein (HDL) binding activity in cultured granulocytes before and after metabolic control of non-insulin-dependent diabetes mellitus ([NIDDM] type 2 diabetes) patients. In 20 type 2 diabetic patients, diabetic control was accomplished by administration of oral antidiabetic agents and dietary restrictions. Adequate metabolic control was reflected by a decrease in the fasting glucose, glycosylated hemoglobin (HbA1c), mean insulin, and body mass index (BMI). After control of the diabetes, the mean HDL3 cholesterol was increased from 0.918 +/- 0.05 to 1.008 +/- 0.05 mmol/L (P < .05) and apolipoprotein AI (apo AI) was increased from 103 +/- 5.8 to 115 +/- 5.1 mg/dL (P < .01). The HDL3 maximum specific binding was higher after versus before diabetic control, 77 +/- 6 versus 122 +/- 8 ng/mg cell protein (P < .01). This increase was related to an increase in maximum binding ([Bmax] from 4.97 x 10(-10) to 8.3 x 10(-10) mol/L, P < .001), and no significant changes were observed in the Kd (from 1.47 x 10(-7) v 2.04 x 10(-7) mol/L). These results suggest that the metabolic control of type 2 diabetes increases HDL3 binding activity.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
