INFLUENCE OF PLASMA FROM A VARIETY OF STRESSED ANIMALS ON I$sup 131$ UPTAKE IN CHICK EMBRYOS
Plasma from rats, guinea pigs, and rabbits exposed to whole-body x irradiation when injected into 15 day old chick embryos elicits a significant increase in the I/sup 131/ uptake of the thyroid. The time post x irradiation when the exposed animal is bled is critical to the elicitation of the phenomenon. No threshold dose was determined in the rat for this phenomenon. The thyroid and pituitary glands seem to be essential in order to elicit the response while the adrenal is not. Plasma from rats subjected to the stress of violent exercise or abnormal environmentai temperatures does not consistently elicit the phenomenon. Plasma from starved rats causes a significant depression in the I/sup 131/ uptake in the chick embryo. (auth)
