1. Effects of endosulfan, malathion and carbaryl on circulating T4, T3 and T3/T4 ratio in the freshwater catfish, C. batrachus have been studied during reproductively active phases, i.e. vitellogenic and post-vitellogenic phases of its annual reproductive cycle. 2. Endosulfan provoked a significant increase in T4 and a decrease in T3 as well as the T3/T4 ratio. 3. Malathion decreased T3 and T3/...

We have previously reported that there is a poor correlation between increase in the levels of UDP-glucuronosyltransferases, UGT1A1 and UGT1A6, and decrease in the levels of serum total thyroxine (T4) and free T4 in phenobarbital (PB)-treated rats, although the PB-induced decrease in rats is generally thought to occur through induction of the UDP-glucuronosyltransferase (T4-UDP-GT: UGT1A1 and U...

PURPOSE Current management for patients with differentiated thyroid cancer includes near total thyroidectomy and radioactive iodine therapy followed by administration of supraphysiological doses of levothyroxine (L-T4). Although hyperthyroidism is a well known risk factor for osteoporosis, the effects of L-T4 treatment on bone mineral density (BMD) in patients with thyroid cancer do not appear ...

PURPOSE We compared the results from a video-assisted thoracoscopic sympathectomy (VTS) at the T4 denervation level with those from a VTS at the T3 level for the treatment of palmar hyperhydrosis (PH). METHODS Seventy patients with PH were prospectively followed for VTS at the T3 or T4 denervation levels for 6 months. The end points of this study were: absence of PH, compensatory hyperhydrosi...

Objective: The primary aim of this study was the early detection and treatment of hypothyroidism in neonates. This paper describes the determination of cord blood serum T4 and TSH levels, their mean levels, reference ranges and interrelationship. Design: Retrospective analysis of serum T4 and TSH levels in 1153 cord blood samples collected and analyzed during July 1998 to June 2000. Setting: Ce...

The well known effect of T4 administration is suppression of TSH level in plasma; with small doses of T4 has been shown to potentiate goitrogenesis induced by goitrogenic drugs. The effects of hort term treatment with sm3.11doses of T4 on plasma and pituitary TSH levels were studied in mice, Very sm3.11doses of T4 caused an increase in circulating TSH while larger dose produced the usual decrea...

Free radicals are all known to damage cell components. The present study was designed to evaluate the free radical generation in the testis and liver and also to determine the testicular and hepatic antioxidant enzyme activities with and without catechin administration in thyroxine induced male Sprague-Dawley rats. The experimental animals were divided into four groups, six on each division. L-...

Endoscopic thoracic sympathectomy is routinely used to treat severe hyperhidrosis. It is usually performed at the T2-T3 level of the nerve, but may produce less severe compensatory hidrosis if performed at a lower level. This study evaluates the outcome of 1,274 patients who underwent endoscopic thoracic sympathectomy for plamar, plantar, axillary or facial hyperhidrosis/blushing. Half of the p...

The purpose of this study was to determine the expression of genes encoding various sarcoplasmic reticulum components that are functionally coupled with calcium release, uptake, and storage function during cardiac hypertrophy induced by thyroid hormone. Hyperthyroidism was induced in two groups of rabbits by the injection of 200 micrograms/kg L-thyroxine (T4) daily for 4 days (T4-4-day group) a...

In bacteriophage T4 the protein product of gene 43 (gp43) is a multifunctional DNA polymerase that is essential for replication of the phage genome. The protein harbors DNA-binding, deoxyribonucleotide-binding, DNA-synthesizing (polymerase) and 3'-exonucleolytic (editing) activities as well as a capacity to interact with several other T4-induced replication enzymes. In addition, the T4 gp43 is ...
