概括
高尿度 (UIC) 与格雷夫斯病患者的放射性摄入量 (RAIU) 的降低有关. 治疗前UIC查可以帮助优化放射性治疗格雷夫斯病.
科学领域:
- 内分泌学 在内分泌学.
- 核医学就是核医学.
背景情况:
- 放射性-131 (RAI) 治疗是格雷夫斯病 (GD) 的首要治疗方法.
- RAI治疗的有效性取决于甲状腺摄入量 (RAIU),而甲状腺摄入量可能会受到患者的状态的影响.
- 了解状态和RAIU之间的关系对于优化RAI治疗结果至关重要.
研究的目的:
- 在新诊断出格雷夫斯病的个体中调查尿度 (UIC) 和RAIU之间的相关性.
- 为了确定的状态,按UIC测量,影响RAIU在药物先验GD患者.
主要方法:
- 对248名新诊断的,从未服用过药物的格雷夫斯病患者进行了回顾性分析.
- 使用-催化光谱测量尿度 (UIC) 的测量.
- 在服用-131后,对2小时,4小时和24小时放射性摄入量 (RAIU) 的评估,并使用皮尔森相关性和线性回归进行相关性分析.
主要成果:
- 观察到UIC的中位数为222.52μg/L.
- 升高的UIC与RAIU在2,4小时和24小时表现出显著的反相关性 (r = -0.15至 -0.28,P < 0.015).
- 与正常UIC (100-300μg/L) 患者相比,UIC> 300μg/L的患者在RAIU中表现出15-20%的减少.
结论:
- 尿液中较高的度与格雷夫斯病患者的放射性摄入抑制有关.
- 对UIC的治疗前查对于优化放射性治疗剂量和规划至关重要.
- 这些发现在饮食中摄入量变化的地区尤为重要.

Synthesis and Regulation of Thyroid Hormones
7.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Redox Titration: Iodimetry and Iodometry
5.6K
Iodometry and iodimetry are analytical methods used to determine the concentration of oxidizing or reducing agents using iodine. In iodometric titrations, the oxidizing analyte solution is usually acidified and treated with an excess of iodide ions, which generates an equivalent amount of iodine in equilibrium with triiodide. The released iodine is subsequently titrated directly against a standardized reducing agent. As the dilute iodine color becomes pale yellow, a few drops of freshly...

Precipitation Titration Curve: Analysis
1.8K
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of chloride ions with silver nitrate, the precipitation titration curve is divided into three regions: before, at, and after the equivalence point. Before the equivalence point, low redissolution of the sparingly soluble silver chloride precipitate gives a low silver ion concentration. However, in the second region, representing the equivalence point,...

Imaging Studies III: Computed Tomography
286
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography
1.1K
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...
