[General morphological characteristic of the glands in trachea and primary bronchi].

The aim of this study was to examine the microanatomical structure of tracheal and bronchial glands in postnatal ontogenesis. The glandular apparatus of these organs was studied in 130 people of both sexes and different age groups (from the newborns to long-livers) using the macro-microscopical and histological methods. The results of these studies indicate that the shape of the glands in trachea and primary bronchi, as well as their numbers and dimensions are subject to great variability.

[Surgical strategy for perforating typhoid ulcers].

The authors share their experiences with operative treatment for perforation of typhoid ulcers in 15 patients. The dissection of ulcerous infiltrate followed by simple suturing was fulfilled in 4 out of these patients against the background of diffuse purulent peritonitis. All the patients died.

[Immediate results of the treatment of gunshot wounds of the large intestine].

Under analysis were the strategy and results of treatment of 1264 patients with gunshot wounds of the colon. Isolated injuries of the colon were noted in 32.3% of the patients, 67.

[Body impedance recording in the assessment of stroke volume].

The first derivative of the integral tetrapolar rheogram of the body, body impedance recording, was found to show changes in blood flow in the arterial compression chamber. Evidence was given for a close relation of the distance between the electrodes while recording an integral rheogram of the body and the examinees' height. The relation of the distance to the examinees' height was equal in males and females and proved to be lower than that previously applied.

[Accuracy of the rheographic method of evaluating stroke volume].

The results of stroke volume determination by means of integral tetrapolar body rheography (ITBR) and M-echocardiography were compared in 78 individuals, while Doppler cardiography was used as the reference method. Fairly high accuracy of stroke volume measurement by ITBR and its advantages over echocardiography, particularly the possibility of calculating the stroke volume irrespective of the heart size, are demonstrated. The accuracy of the ITBR determination declines in patients with severe heart failure.

[Tetrapolar modification of integral body impedance plethysmography].

A decrease in the amplifying ratio of inlet high-frequency amplifiers makes it possible to use PPG2-02 apparatus for tetrapolar modification of integral body impedance plethysmography (IBIP) without the currently used accessory device - divider. In 15 subjects impedance was measured using PPG-01 apparatus in the modification of M. I.
