The action of L-triiodothyronine (T3) on amino acid transport in the GC clonal strain of rat pituitary cells was investigated by measurement of the uptake of the nonmetabolizable amino acid, alpha-aminoisobutyric acid (AIB). The uptake of AIB by GC cells appeared to require energy and Na+ and displayed Michaelis-Menten kinetics. In comparison to cultures maintained in the absence of T3, T3 addi...
We developed a novel noncompetitive immunoassay format for monoepitopic analytes and describe here a model assay for triiodothyronine (T3), performed on Ciba Corning's ACS:180 analyzer. Acridinium ester (AE)-labeled bivalent anti-T3 was incubated with the sample, producing AE-anti-T3/T3 complexes and unreacted AE-anti-T3. Controlled-pore glass particles (CPG) with immobilized diiodothyronine (T...
INTRODUCTION. It has been shown that inflammation affects thyroid function. In patients with end-stage renal disease, low plasma triiodothyronine (T3) may be an unsuspected expression of the inflammatory state of these patients. This study evaluated the correlation between T3 and high-sensitivity C-reactive protein (HSCRP) levels in patients on peritoneal dialysis (PD) and hemodialysis. MATERIA...
E. coli B cells infected with T3 phage contain a modified host RNA polymerase in addition to the normal RNA polymerase found in uninfected cells. The modified RNA polymerase behaves differently in its elution properties from the normal enzyme on DEAE-cellulose, phosphocellulose, and DNA-cellulose column chromatography. The modified enzyme also differs from the normal polymerase in some of its e...
سابقه و هدف: داروی کابرگولین آگونیست دوپامینرژیکی قوی مشتق شده از قارچ ارگوت است که با وجود اهمیت آن در درمان برخی اختلالات مثل هیپرپرولاکتینمیا، دارای اثرات جانبی مهمی بر محورهای آندوکرینی بدن است. هدف از تحقیق حاضر، تعیین اثرات کابرگولین بر غلظت سرمی هورمون های تری یدوتیرونین (3t)، تیروکسین (4t) و هورمون محرکه تیروئیدی (hst) در موش صحرایی نر بالغ بود. روش بررسی: در این مطالعه تجربی، از ٤٠ سر...
درحال حاضر کرم های روشن کننده گوناگونی برای درمان لکه های پوستی در دسترس می باشد اما مهمترین ، متداول ترین و موثرترین آنها کرم هیدروکینون و یکی از جدیدترین آنها کرم کوجیک اسید می باشد. اگرچه سابقه مصرف مواد روشن کننده بسیار طولانی می باشد امادر خصوص ایمنی آنها در مصارف طولانی مدت اطلاعات متضادی وجود دارد. در این تحقیق و براساس پروتوکل404 و 422 oecd سمیت مزمن و سیستمیک کرم های روشن کننده ایرانی ...
In euthyroid sick syndrome [non-thyroidal illness (NTI)], a number of investigators have described TSH and serum thyroid hormone abnormalities, low T3, low T3 and T4, increased T4, low TSH, etc. Those cases of NTI where there is only T3 decrease [and normal serum T4, free T4 (FT4), and TSH levels] are specifically referred to as low T3 syndrome. However, the information in regard to low T3 synd...
To study the protective effects of maternal thyroxine (T4) and 3,5,3'-triiodothyronine (T3) in congenital hypothyroidism, we gave pregnant rats methimazole (MMI), an antithyroid drug that crosses the placenta, and infused them with three different doses of T4 or T3. The concentrations of both T4 and T3 were determined in maternal and fetal plasma and tissues (obtained near term) by specific RIA...
Tocotrienol (T3) is an unsaturated vitamin E having health benefits (e.g., anti-angiogenesis). We measured T3 in commercial eggs, and developed T3-fortified eggs by adding rice bran scum oil (RBO, containing 1.3% T3) to the feed. Commercial eggs contained about 0.11 mg of T3/egg, while the T3 content was improved to 0.62 mg/egg after RBO supplementation to the feed of hens for 7 d.
