Abstract:
The effect of alcohol on urinary glycosaminoglycan (GAG) and protein excretion was studied in one-month-old normal control C57BL/6J (CBL) and genetically diabetic (db/db) mice. Ethyl alcohol (4 g/kg) was given once a day by gavage for 58-64 days. Increased amounts of urinary total GAGs and protein were found in diabetic mice. Alcohol treatment increased urinary excretion of total GAGs, heparan sulfate and protein only in nondiabetic CBL but not in diabetic mice. Also, alcohol increased creatinine clearance only in CBL mice. The reason for the lack of effect of alcohol in diabetic mice is unknown. A significant positive linear relationship was found between urinary total GAG and protein concentrations. Possible significance of this relationship in diabetes is discussed.
