Although the application of radiotherapy techniques reduced normal lung tissue of exposure for patients with non-small cell lung cancer, Radioactive Pneumonia (RP) and Pulmonary Fibrosis (RF) are still frequently occurred in the processes of lung cancer radiotherapy. Plasminogen Activator Inhibitor-1 (PAI-1) plays a crucial role in the process of lung injury during RP in lung cancer patients. H...

1. The oral absorption and the rate of loss from the body of radioactive iron were measured by whole-body monitoring in patients with functioning renal homografts. The incorporation of radioactive iron into erythrocytes was also measured. 2. The results were compared with corresponding values in normal subjects and in non-dialysed and dialysed patients with chronic renal failure. 3. The mean or...

group. The object oP thIs study has been to assess the influence of an expanded hepatic pool of copper on the incorporation of radioactive copper into caeruloplasmin. 2. Studies with 67CU have shown that radioactivity disappears steadily from the plasma of patients with Wilson's disease for periods up to 296 h. Both in patients with primary biliary cirrhosis and in controls, a well-marked secon...

the present nuclear leakage crisis from japan is a topic to be discussed in present public health. in radiology, the leaked radioactive elements are considered hazard. here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. based on previous similar nuclear crisis in russia, it is eviden...

background : sentinel lymph node biopsy is a technique used to identify the axillary node most likely to contain tumor cells that have metastasized from a primary carcinoma of the breast. this technique provides accurate staging with fewer complications than axillary dissection and may result in decreased costs. we designed the present study to determine the accuracy and success rate of a combi...

BACKGROUND Recent reports demonstrate that intracoronary radiation affects not only neointimal formation but also vascular remodeling. Radioactive stents and catheter-based techniques deliver radiation in different ways, suggesting that different patterns of remodeling after each technique may be expected. METHODS AND RESULTS We analyzed remodeling in 18 patients after conventional stent impl...

Preliminary treatment with carbimazole in a series of 181 patients with thyrotoxicosis selected for treatment with radioactive iodine did not make any significant difference to the subsequent response to (131)I therapy.

In a series of 156 thyrotoxic patients treated with low doses of radioactive iodine the therapeutic dose was calculated by means of a sliding scale in which the dose level was varied according to the estimated size of the gland. Of the patients so treated 56.5% achieved a remission with a single dose of (131)I. The incidence of hypothyroidism at one year was 5%.
