Task: Answer Verification
Input (English): Question: Does selective blockade of cholecystokinin type B receptors with L-365,260 impair gallbladder contraction in normal humans?
Answer: Multiple oral doses of L-365,260 do not alter ultrasonographically assessed gallbladder contraction at doses shown to be clinically effective in earlier studies. Despite being more difficult to implement, the sum of cylinders method for estimating gall bladder size offers no advantage over the ellipsoid method.
Output (English): no
