A method of therapeutic starvation was employed in preoperative preparation of 63 surgical patients with morbid obesity. The authors managed to achieve average reduction in body weight of the patients by 10-20% with correction of concomitant diseases. Good tolerance to therapeutic starvation of the patients and increase in their resistance to the operative stress were noted.

During and after space missions crew members showed significant vestibular changes. The cosmonaut-researcher of the orbital complex Soyuz T-7--Salyut-7 developed inhibition of compensatory and enhancement of nystagmic eye movements in response to active head movements in the frontal plane. During an acute stage of readaptation crew members of the orbital complex Soyuz T-4--Salyut-6 displayed attenuation of the oculomotor reaction to optokinetic stimulation. One of them exhibited overt asymmetry of this oculomotor reaction. This cosmonaut also developed distinct spontaneous nystagmus in the dark and floating eye movements when he tried to fix his gaze at a stationary object. These findings give evidence that space flight may induce vestibular asymmetry and disorders of mechanisms of opto-vestibular interaction.

Alimentary deprivation was used in preoperative treatment of 86 surgical patients with obesity. Body mass was reduced by 10 to 20%, on an average, and the course of concomitant diseases was corrected. Findings of clinical, instrumental, and laboratory studies showed that alimentary deprivation was well tolerated by surgical patients, improving their resistance to surgical stress.
