The acute effect of garlic oil and DADS on oral glucose
tolerance was studied on day 3 after these compounds were administered to the animals for the first time (Fig. 3).
Under fasting conditions, administration of the garlic compounds
did not significantly affect blood glucose concentrations
within 30 min. After oral glucose loading, blood
glucose concentrations in the vehicle-, garlic oil-, and
DADS-treated diabetic rats were all dramatically increased
and were higher than those of the control animals (Fig. 3).
Thus, there was no short-term effect of garlic oil or DADS
on either fasting blood glucose concentrations or oral
glucose tolerance in diabetic rats.
