A Comparison of the Effects of Hypophysectomy and Pinealectomy on the Organs' Weights of Rana pipiens

Abstract

The purpose of this paper was to observe and compare the changes that occurred in organ weights as a result of hypophysectomy and pinealectomy of the frog, Rana pipiens in order to determine whether there is a correlation between the actions of the pineal body and the hypophysis in an amphibian possessing a photoreceptor-type pineal body.
