MATERIALS AND METHODS Male Wistar rats (Dept. of Zoology, Univ. of Graz) of 220-250 g
body weight were studied. They had free access to tap water and Purina chow in a room …

Circulating thyroxine (T4) and triiodothyronine (T 3) concentrations in rhesus monkeys were
determined after various periods of cadmium administration in diet. No significant change in …

The effect of cadmium on thyroxine (T 4) outer ring monodeiodination was studied in vivo
and in vitro in the rat liver. One microgram of T 4 was incubated with rat liver homogenates in …

The effect of in vitro addition of zinc sulphate on T4 deiodination in brown adipose tissue
(BAT) of rats exposed to 4 degrees C or 22 degrees C temperature during 24 h, was studied …

The effects of cadmium on 5′-deiodination of thyroxine (T 4) by rat liver and on the hepatic
concentration of non-protein sulfhydryl groups (NPSH) were studied in Wistar rats of 200 …

Exposure to heavy metals such as cadmium and mercury is of immediate environmental
concern. The present study was aimed at establishing a direct relationship between heavy …

MATERIALS AND METHODS Thyroidectomized and normal male rats, weighing
approximately 200 g, were purchased from Badger Research Corp., Madison, Wisconsin. All …

The effects of L-thyroxine (T4) treatment upon hepatic metabolism of control and T4 treated
rats was studied. Livers were excised and freeze-clamped rapidly. The levels of adenine …

MATERIALS AND METHODS Twenty eight adult male Swiss mice weighing 25-30 g were
housed in temperature (27±1 C) and light controlled (14 hr light: 10 hr dark) room with the …

Previous reports suggest that a type II iodothyronine 5'-deiodinase may become the main
enzymatic pathway for extrathyroidal triiodothyronine (T3) generation when the enzyme …
