SUMMARY In a significant proportion of patients with thyroid disorders, thyroglobulin antibodies (TgAb) invalidate double‐antibody radioimmunoassays (RIA) for (Tg). A modified RIA procedure determining serum Tg in the presence TgAb, is described. Two measurements are made on each sample. Ratio immunoglobulin (Ig)‐bound to free (bound:free ratio). This measured by distribution trace quantity 125 I‐Tg between bound and fractions. Concentration free, i.e. unbound thyroglobulin. supernatant...
Summary Iodine Metabolism in Relation to Reproductive Status Cows Studies were made on the phases of thyroid function as revealed by determination weight, thyroidal total and organic iodine well protein bound hormone potency sera cows during stages estrous cycle, pregnancy those affected with cystic ovaries. 1. The fresh weight was maximal at proestrus relatively increased pregnancy. 2. concentration minimal estrus ovaries, indicating depletion from a result estrogen level blood. thyroids...
The clinical value of four laboratory methods assessing free thyroxine status was compared in 82 consecutive patients newly referred to a thyroid clinic with suspected dysfunction. determining used were: (1) index using hormone uptake test (FTI (THUT)); (2) binding globulin (TBG)); (3) kinetic radioimmunoassay (Immophase); and (4) an equilibrium dialysis method. definitive evaluated by combination assessment (including Wayne index), routine tests function (total T4, T3, TSH, TRH where...
<h3>Background</h3> The Psoriatic Arthritis Impact of Disease (PsAID) is a patient-reported questionnaire assessing multiple domains in patients with psoriatic arthritis (PsA), developed under the aegis EULAR, and recommended by OMERACT GRAPPA. To be usable different contexts, translations cross-cultural validations are necessary. Arabic sixth most-spoken language world; however, many outcomes not available Arabic. <h3>Objectives</h3> translate, culturally adapt validate PsAID-12 Arabic, to...
Summary The activity of the thyroid glands buffaloes as related to reproductive stages and ovarian abnormalities was studied. For this purpose fresh dry weights thyroids their inorganic protein-bound iodine were determined. Histological studies such also made. It found that heavier at proestrus in mid-and late pregnancy. content low estrus during pregnancy, especially last stages, indicating increased gland. epithelial cell height amount colloid small. with cystic ovaries relatively active...
Summary Studies were made in mature female rats to determine the thyrotrophic-hormone-releasing factor (T-RF) present hypothalamus at different stages of estrous cycle and ovariectomized animals. At same time TSH content pituitaries sera these determined. It appeared that (1) T-RF was its maximum proestrus, (2) concentration high during early estrus maximal diestrus, (3) serum late estrus. An interpretation results is discussed. Zusammenfassung Die hypothalamische Regulation der Sekretion...
Summary The level of thyroid hormones in the glands Egyptian buffaloes at various reproductive stages was determined by a radioactive technique. results indicate no significant difference between pregnancy. In inactive ovaries ratio iodothyronins to iodotyrosines is high. pregnancy middle stage shows higher iodotyrosine iodothyronine but this not due small number animals used. There highly two types hormone case metestrus and moderately preostrus oestrus, while insignificant dioestrous...
Summary The possible mechanisms by which oxytocin and hysterectomy control development involution of the corpora lutea rabbits were studied. It was found that degenerative changes leading to corpus luteum are not a result merely time but appear be an imbalance between luteotropic luteolytic factor reaching ovary via blood. In activity pitocin is achieved decreasing blood supply stimulating formation white fibrous connective tissue. This results in degeneration luteal cells. action mediated...
<h3>Background</h3> In patients with psoriatic arthritis (PsA), discordance between physicians and when assessing disease activity has been described as frequent, mainly in European North American studies. This may negatively impact treatment adherence shared decision-making processes. Culture beliefs influence patients' perceptions of health. <h3>Objectives</h3> To evaluate the concordance patient- (PGA) physician-global assessment (PhGA) PsA its association demographic characteristics a...
ObjectivesThe Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire is the recommended measure patient-reported impact for psoriatic arthritis (PsA); it was developed in Europe and may not be valid all cultures. The objective to translate, culturally adapt validate PsAID Arabic.Methods PsAID-12 translated into Arabic (double translation, back-translation, cognitive debriefing), then validated through a study conducted 13 Arab countries 2022. Participants were consecutive literate...
The thyroid hormone level in the serum of 240 sheep (120 males and 120 females) was studied, using stasis tadpole method, to determine effects season sex on its level. following results were obtained: maximal observed during winter (Dec. — Feb.) about 5 times that obtained summer (June August). Increased day length, as well high ambient temperature, depressed activity. coefficient correlation regression between these factors estimated. No statistically significant differences found due...
Summary Studies were made of the effects sexual maturity, stages estrous cycle, and sex hormones on uptake I 131 ‐labelled l‐thyroxine by certain tissues mice. It was found that: 1. The l‐thyroxine‐I skeletal muscle female mice maximal at metestrus as compared with other cycle immature females. 2. radiothyroxine mature male greater than that 3. Administration estradiol or testosterone to ovariectomized resulted in increased muscle; progesterone antagonised this action estradiol....
