Surgery for Ascending Aortic Aneurysm and Aortic Valve Insufficiency in Conditions of Active Proceeding Syphilitic Aortitis and Valvulitis.

A syphilitic aortitis is a late cardiovascular lesion of tertiary syphilis that has become exceptionally rare in the antibiotic era but not eradicated completely. Syphilitic aortitis of ascending aorta complicates in ascending aortic aneurysm formation and aortic valve regurgitation, both requiring surgical treatment. After surgery, lifelong surveillance of the remainder of the aorta is recommended because of a priori supposed high incidence of delayed involvement of noninvolved aortic segments.

[Influence of mental rotation of objects on psychophysiological functions of women].

An integral part of activity of modern human beings is an involvement to work with the computer systems which, in turn, produces a nervous - emotional tension. Hence, a problem of control of the psychophysiological state of workmen with the purpose of health preservation and success of their activity and the problem of application of rehabilitational actions are actual. At present it is known that the efficiency of rehabilitational procedures rises following application of the complex of regenerative programs.

[Modulation of the functional activity of the acoustic and visual analyzers under conditions of listening to one's own EEG acoustic image of the temporal and occipital cortex areas].

Investigation into the functional activity of the acoustic and visual analyzer has been carried out before and after procedures of listening to one's own EEG of the temporal and occipital cortex areas. It has been shown, that there is a dependence of the dynamics of latent periods of sensomotor response to modality of stimuli and localization of source of the EEG acoustic image. After listening to acoustic image of the temporal EEG, a reduction of sensomotor reaction latency in the acoustic test has been observed.

Tumour pH drop after cryotreatment and enhancement of hyperthermia antitumour effect.

Our previous study demonstrated a selective drop of pH, PO2 and blood flow in tumours under induced hyperglycaemia that enhanced the antitumour effect of hyperthermia. However, there are contraindications restricting the use of hyperglycaemia. Cryotreatment, as a method of altering tumour microphysiology similar to hyperglycaemia, was investigated.

[Effect of cryodestruction of Lewis lung carcinoma in mice on the development of metastases].

The effect of the primary tumour cryodestruction on a degree of metastatic spreading in the lungs was investigated in experiments with C57B1/6 mice with Lewis carcinoma of the lungs. It is found that after the tumour cryosurgery there was a less quantity of metastases as compared with operated animals (surgical removal of the tumour or amputation of the limb with the tumour) or with untreated animals. A regular correlation is observed between the degree of metastatic spreading and the efficiency of the primary tumour treatment.
