Contractile characteristics of the rat stomach strip and the rabbit aorta and mesenteric artery.
A comparison was made of the dose-response curves obtained in the measurement of the prostaglandin E- and thromboxane A2-like activities using a cascade system consisting of a rabbit aorta strip and mesenteric artery and a rat fundus strip. The results indicate that the contractile properties of these tissues are different. In platelets during aggregation, the TxA2-like activity was measured by bioassay; the amount of TxB2 by a radioimmunological method.
