spheroidal and ring nucleoli in amphibian oocytes. patterns of uridine incorporation and fine structural features.in maturing oocytes of the newt triturus viridescens, the nucleoli undergo a series of morphological changes that are very similar to those described by callan for the axolotl, ambystoma mexicanum. the nucleoli first assume the form of spheroids which then become extended into ring or necklace shapes that are dnase-sensitive; in mature oocytes the nucleoli revert to a spheroidal form. short term in vitro incorporation studies with uridine-(3)h on both species show that rna synthesis occurs in a ...19676055993
the formation, distribution and function of ribosomes and microsomal membranes during induced amphibian metamorphosis.1. a lag period of about 4 days preceded the onset of metamorphosis precociously induced by tri-iodothyronine in tadpoles of the giant american bullfrog (rana catesbeiana). it was established by the accelerated synthesis or induction of carbamoyl phosphate synthetase and cytochrome oxidase in the liver, serum albumin and adult haemoglobin in the blood, acid phosphatase in the tail, and the increase in the hindleg/tail length ratio. 2. a 4- to 6-fold stimulation, 2 days after the induction of met ...19675584018

studies on the advent of ureotelism. factors that render the hepatic arginase of the mexican axolotl able to hydrolyse endogenous arginine.1. a study was undertaken of the conditions that might operate in the synthesis and hydrolysis of arginine by axolotl liver homogenate to test a previous postulate that liver arginase of the non-metamorphosed mexican axolotl is not able to hydrolyse arginine formed from citrulline and aspartic acid, though it can split exogenous arginine, and also that an enhanced capacity to hydrolyse endogenous arginine plays a major role in the advent of ureotelism observed during the metamorphosis of the axo ...19685701670

transplantation of axolotl heads.favorable conditions for organ transplantation exist for some populations of european laboratory axolotls, making transplantations of heads possible. survival of the transplants is prolonged because homograft reactivity of the host animals is absent. heads transplanted to the backs of other axolotls grow rapidly and show many reactions characteristic of normal axolotl heads. the behavior of the transplants is independent of that of the host animals.19685683054

studies on the advent of ureotelism. the effects of bivalent cations on the capacity of the hepatic arginase of the mexican axolotl to hydrolyse endogenous arginine.1. the effects of 19 bivalent cations on the activity, stability and capacity to hydrolyse endogenous arginine of axolotl liver arginase were studied. 2. it was found that fe(2+), co(2+), ni(2+) and zn(2+), as well as mn(2+), stabilize the enzyme and render it able to hydrolyse endogenous arginine. 3. by using different concentrations of co(2+) and ni(2+) it was possible to dissociate the effect of each of the metal ions on the activity and stability of arginase from that on its capacity to hydr ...19695820633
