Endoscopic diagnosis of postoperative stomach cancer]

The authors examined endoscopically the esophagus and stomach in 309 patients, previously operated upon for gastric cancer (258), ulcer of the stomach or duodenum (36) and benign gastric tumors (15). They estimated the value of this method for establishing diagnosis of the operated stomach cancer and also the importance of histological and cytological methods in the complex diagnosis of this pathology. Moreover, roentgeno-endoscopic correlations were made. Cancer of the operated stomach was detected in 59 patients, it was suspected in 8, other lesions were found in 194. no changes in the operated stomach were found in 48. It is stated that endoscopy is more advantageous than roentgenological examination in establishing the diagnosis of tumor pathology of the operated stomach. Histological and cytological findings are of considerable value in making the correct diagnosis. These methods are mostly informative in an exophytic form of the tumor growth.     

Study of the seizure threshold and increasing resistance of rats to stress after immunization to diazepam-binding inhibitor fragment

Simultaneous surgery in gastroduodenal ulcer

The results of 96 simultaneous operations for peptic ulcer are discussed. The indications for their performance are substantiated and the principles of their conduction in various diseases aggravating one another are determined. The low incidence of postoperative complications (4.2%) and lethality (1.04%) are evidence of the expediency of the suggested tactics.     

Bronchoscopic diagnosis of peripheral lung cancer

The diagnostic value of bronchologic procedures in identification of peripheral cancer of the lung versus tumor's size, endoscopic pattern of bronchial lesion and tumor position with respect to the root of the lung was assessed. Rigid endoscopes and bronchofibroscopes were used in 806 patients with peripheral lung cancer. Bronchoscopic diagnosis of cancer was morphologically confirmed in 64.9% (respiratory endoscope alone--51.3 +/- 3%; bronchofibroscope or combined use of both devices--71.9 +/- +/- 2%).     

Reliability and effectiveness of monitoring the stroke and minute volume of the heart by Kubicek's rheographic method

Simultaneous measurements by the Fick direct method and the Kubicek rheographic method of cardiac output of 20 men with ischemic heart disease have shown that both methods are well correlated (r = 0.76, k = 0.92, n = 41). The reproducibility of the Kubicek data was slightly better than the Fick data (on the average +/- 6% instead of +/- 9-10%). An attempt of increasing the correlation of the Kubicek data with the Fick data by correcting the specific resistance with respect to the hematocrit data and the chest perimeter failed. In order to provide the necessary accuracy of the Kubicek method, it is required that the procedure be stringent and the five variables in the formula for calculating cardiac output be precisely measured. The cardiac output values determined simultaneously by the Kubicek method and by x-ray contrast ventriculography showed a better correlation (r = 0.88, k = 0.97, n = 15).
