Evidence of thyroxine formation following iodine administration in Sprague-Dawley rats.
Iodine (I2) has been proposed to be used as a water disinfectant on the manned space station. Previous work has shown that subchronic administration of I2 to Sprague-Dawley rats in drinking water significantly increases plasma thyroxine/triiodothyronine (T4/T3) levels. This is not observed with iodide (I-) treatment. The present study addresses the possibility that I2 reacts with deiodinated T4...
متن کاملThe Effect of Thyroxine and Dinitrophenol on Sperm Metabolism*
In continuation of our studies on the metabolic processes involved in furnishing energy to the mammalian sperm cell a study has been made of the effect of certain metabolic accelerators. Carter (1) has reported that the respiration of rabbit epididymal spermatozoa may be increased by thyroxine by as much as 200 per cent under certain conditions, and has postulated a r61e of thyroxine in the mat...
متن کاملEffects of endogenous production and exogenous administration of H2S on gastric acid secretion in rats
Introduction: Recently, hydrogen sulfide has been introduced as the third gas that acts as a transmitter. It has many physiological and pharmacological roles in the human body. The aim of the present study was to investigate the effect of exogenously administered and endogenously produced H2S on the basal and distention-induced gastric acid secretion in rats. Methods: Forty-nine male Wistar...
متن کاملDecreased serum triiodothyronine in starving rats is due primarily to diminished thyroidal secretion of thyroxine.
Although thyroxine (T4) 5'-deiodinase activity is diminished in liver homogenates of starved rats, no information is available regarding the effect of starvation on net T4 to triiodothyronine (T3) conversion in the intact rat. It appeared important to clarify this relationship since rat liver homogenates are widely used as a model for the study of the factors responsible for reduced circulating...
متن کاملIncreased Excitability of Lateral Habenula Neurons in Adolescent Rats following Cocaine Self-Administration
BACKGROUND The lateral habenula is a brain region that has been critically implicated in modulating negative emotional states and responses to aversive stimuli. Exposure to addictive drugs such as cocaine negatively impacts affective states, an effect persisting longer than acute drug effects. However, the mechanisms of this effect are poorly understood. We hypothesized that drugs of abuse, suc...
