[Mechanisms of inhibiting thymus endocrine function in tumor growth].

The experiments were conducted on a model of intraorganic growth of Geren carcinoma (GC) in spleen of non-linear mice. It has been shown that titer of thymic serum activity (TSA) decreased sharply in the blood at a stage of settling transplants down (7th day), while the level of an inhibitor for thymic serum factor (FTS) increased in a statistically significant way. At progressive tumor growth, the level of TSA in the circulation raised a little on the 10th day but it was still reduced in comparison with that before inoculation of GC.

[Endocrine function of the thymus in experimental hypothyroidism].

An Endocrine function of the thymus was studied by analyzing the level of thymulin in rats in 1-6 months after extirpation of the thymus. The level of thymulin in rats after thyroidectomy has been shown to be reduced maximally in 6 months after an operation. An inhibitor of thymulin was detected in the blood serum in a month after extirpation, then it disappeared completely from it.

[The catamnesis of patients with cerebral circulatory disorders in stenosing and occlusal lesions of the extracranial branches of the internal carotid artery who were treated surgically and who were not].

A catamnestic follow-up was carried out of 70 patients presenting with recurrent cerebral circulatory disorders (CCD). Of these, 35 were patients operated on, with other 35 on drug therapy only. A comparative characterization of catamnesis of patients with stenosis of intracranial portions of internal carotid artery (ICA), operated- and non-operated on, showed that recurrent ischemic insult occurs three times as frequently among the nonoperated--on patients than it does among those operated on, with recurrent transitory CCD being seen only in the patients nonoperated on.

[Clinico-structural changes in the brain in cerebrovascular insufficiency].

Overall seventy patients with chronic hypertensive encephalopathy and acute cerebral circulatory disorders were examined, their age ranging between 35 to 75 years, by ACT, MRT, USG. MRT was found out to be the most objective method for identifying structural changes in the brain in cerebrovascular disorders. The main signs of MR-tomography are vascular changes presenting as lacunar infarctions with or without perifocal area of edema, hydrocephalus, brain swelling, intracranial hypertension, poor differentiation of gray and white substances of the brain, with hygromas being readily identifiable.
