[Hepaticocholedoch reconstruction by explants and autotransplants].

Authors have elaborated new method of surgical correction of hepaticocholedoch strictures. The experiments were carried out on 25 mongrel dogs of both sexes with body weight 15-25 kg. The surgical procedures were done under endotracheal ether narcosis.

[Transcutaneous monitoring of oxygen tension in patients with chronic obstructive lung diseases undergoing physical loading].

Noninvasive monitor-aided transcutaneous determination of oxygen tension--TcPO2 (oxymonitor SM 361, Hellige, FRG) was performed in 32 patients aged 34 to 70 with chronic obstructive pulmonary diseases (COPD) during bicycle ergometry testing of moderate power (300 kgm/min) for 5 min. Respiration biomechanics was investigated before testing in all the patients using the method of total plethysmography (Pulmorex, Fenyves Gut, Switzerland). During testing all the patients were divided into 2 groups with relation to variations of TcPO2 values.

[Determination of non-uniform pulmonary ventilation by transcutaneous measurement of the oxygen tension in the arterial blood under an oxygen load].

A method for determination of uneven ventilation in the lungs by the transcutaneous measurement of oxygen tension in arterial blood (TcPO2) is suggested. The degree of uneven ventilation was estimated by the time of a decrease in the TcPO2 till point of departure (desaturation time) after oxygen inhalation. The TcPO2 was measured by an oxymonitor (Hellige, Model SM 361).
