We have analyzed a group of 163 patients with pituitary adenoma treated by the GK for 5 years. They were followed up for 12–60 months (median 24 months) after irradiation. An antiproliferative effect has been achieved using the minimal dose 16–35 Gy with median of 20 Gy to the tumor margin in all of our patients who were controlled by MRI (n = 126 patients). One-half of these adenomas noticeably decreased...
A separation and preconcentration procedure for Pb and Cd in human hair by using the chelating ion-exchanger, Iontosorb-Oxin, is described. The sorption yield dependence of Pb and Cd, on pH, time, and on the presence of accompanying elements, was investigated. The hair samples were decomposed by microwave irradiation and the determination of lead and cadmium was by flame and electrothermal atomic...
