This study was performed to determine whether TCDD (50 μg kg ; single oral dose) could induce adrenal microsomal lipid peroxidation, which might be correlated to decreased levels of cytochrome P-450 and 21-hydroxylase activity. The amount of malondi

Plasma ACTH concentrations in 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD)-treated rats (50 micrograms/kg; single, oral dose) were 2.1-, 2.1-, 2.9-, 1.7-, 1.5-, 2.0- and 3.0-fold greater than control values, respectively, at days 1, 3, 5, 7, 10, and

The present study assessed the ability of primary cultures of rat anterior pituitary cells to secrete bioactive ACTH in the presence of 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD). The bioactivity of the secreted pituitary cell ACTH was determined

The possibility that habitual voluntary running induces a chronic change in adrenal glucocorticoid synthesis and secretion was examined in freely running mature female hamsters, in whom this behavior accelerates growth, reduces body fat levels, and e

It is known that administration of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes decreased serum testosterone concentrations in the rat. Previous studies in this laboratory have shown that in rats TCDD exposure results in decreased 17 alpha-hydro

The role of nutritional factors on heme synthesis and their influence on the development of anemia in the bone marrow during lead exposure is unclear. Previous reports suggested that pteridines could regulate the formation of uroporphyrinogen, a step

We measured current serum hormone and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) concentrations in 37 men who sprayed 2,4,5- trichlorophenoxyacetic acid (2,4,5-T) in the State of Victoria, Australia. TCDD levels were consistently significantly invers

The present study was undertaken to assess if hypothalamic beta-endorphin (beta E) and/or brain mu opioid receptors are associated with 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) (50 micrograms/kg)-induced hypophagia and body weight decline in rat
