[Evaluation of pulmonary hypertension by dopplerography in patients with nonspecific pulmonary diseases]. / Otsenka gipertenzii malogo kruga krovoobrashcheniia u bol'nykh nespetsificheskimi zabolevaniiami legkikh metodom dopplerografii.

Doppler echocardiography was used to quantify pulmonary hypertension and phase pattern of right heart systole in 140 patients with nonspecific pulmonary diseases to study hemodynamic characteristics of pulmonary circulation and right heart as well as external respiration. There appeared a relationship between the severity of pulmonary hypertension, bronchial obstruction and arterial hypoxemia. It seems that in nonspecific pulmonary diseases hemodynamic changes arise prior to functional disorders of external respiration.

[Low-intensity laser treatment of patients with duodenal ulcer and erosive lesions of gastric and duodenal mucosa]. / Lechenie nizkoénergeticheskimlazerom bol'nykh iazvennoi bolezn'iu dvenadtsatiperstnoi kishki i érozivnymi porazheniiami slizistoi obolochki zheludka i dvenadtsatiperstnoi kishki.

Ninety-eight patients were exposed to low-energy laser irradiation. Of these 52 and 31 had duodenal ulcer in aggravation phase with mucosal erosion and without it, respectively, 15 patients developed isolated erosive lesions of gastroduodenal mucosa. The energy was delivered to the target cites optically using fiber optics endoscope. Microcirculation was studied by bulbar biomicroscopy. Therapeutic response in the laser utilization proved positive being the highest for patients with a short disease history, moderate signs, small-size lesions. Normal microcirculation was not achieved though there was a trend to its improvement.
