The effects of thiourea on the thyroid gland and molting behavior of the lizard, anolis carolinensis

The Ethoecology of Anolis nebulosus (Sauria, Iguanidae)

“…Some of the endocrine and histological changes occurring during anoline ecdysis have been described (Adams and Craig, 1951;Lillywhite and Maderson, 1968;Maderson and Licht, 1967;Ratzersdorfer, Gordon, and Charipper, 1949). Yet the gross aspects of shedding and the associated behavior have been neglected.…”

Thioureas

“…One of the most widely studied aspects of thiourea and its derivatives has been their antithyroid activity. Many experimental results have been published on this subject (4,43,100,126,131,135,156,159,188,192,194,195,212,213,215,229,234,237,238,246,248). There are many discrepancies in the results of the different workers which may, in some cases, be due to differences in testing techniques.…”

THE UPTAKE OF I131BY THE THYROID GLAND OF TURTLES AFTER TREATMENT WITH THIOUREA

“…Young animals resume their secretory activity in February and attain their highest activity in June. Seasonal variations in the thyroid of lizards have also been noted by Ratzersdorfer, Gordon and Charipper (1949) served that the cycle is closely correlated with the various phases of the life history of the animal. He reports the lowest thyroid activity for the fall and an increase in activity during the winter.…”

“…Little work has been done concerning the function of the thyroid in reptiles. Ratzersdorfer, Gordon and Charipper (1949), Adams and Craig (1951) and Fisher (1953) have reported the effects of antithyroid compounds on the lizards. Naccarati (1922) described the normal histology and gross anatomy of the thyroid gland of the turtle Em\s curopa, while Evans and Hegre (1940) studied seasonal changes and the effects of pituitary extract on the thyroid of CJit-yscniys picta belli.…”
