Postoperative chylothorax after injury of the thoracic duct during esophagectomy is a rare but severe complication which may lead to serious problems such as loss of fat and proteins, and immunodeficiency. Without treatment mortality can rise to over 50%. From 1988 to 2005, we treated 10 patients with postoperative chylothorax after 409 resections of the(More)
Cerebral bioelectric activity of 18 healthy test subjects, aged 31-40, was examined during and after their 182-day head-down tilting. The test subjects were divided into a group that performed countermeasures (exercise, muscle stimulation) against hypokinesia-induced disorders and a control group. During the study EEG changes were most pronounced in the(More)
The functional state of the nervous system and its autonomic compartment was investigated in 15 men, aged 40-52 years, during their 30-day exposure to head-down tilt (-8 degrees). Group 1 consisted of 9 subjects with early manifestations of cerebral atherosclerosis and Group 2 included 6 subjects with cerebral atherosclerosis and arterial hypertension. The(More)
Postflight rheographic examinations carried out at rest and during postural tests showed noticeable changes in the vascular regulation and significant blood redistribution. On the recovery day there were no signs of the intracranical venous congestion to weightlessness. The tone of cerebral vessels, however, increased to prevent the development of cerebral(More)
The paper presents rheographic investigations of regional haemodynamics (brain, lungs, liver and limbs) during antiorthostatic exposures of varying intensity (-15, -30, -45 degrees, times of exposure 20, 40 and 60 min). Our findings show that the pattern and time of the function of compensatory mechanisms preventing excessive vascular compliance [correction(More)
In response to simulated space flights cardiovascular and metabolic changes of 86 volunteers, aged 40-49 and 50-56, were similar to those of young people (25-39 years old). In most aged test subjects, the changes produced by 8-day head-down tilt (-8 degrees) and 7-day water immersion were moderate and reversible. This type of variation of the(More)
A method of intraoperative mapping of the lymph outflow tracts was used in 32 patients for a detection of the signal lymph node in gastric cancer using a lymphotropic stain BLUE PATENT V. The test-sensitivity was 78%. The intraoperative mapping of the lymph outflow tracts allows the volume and zone dissection in operations for gastric cancer to be exactly(More)
