[Effect of the intercellular adhesion molecule E-cadherin on the prognosis of non-small cell lung cancer].

The effect of E-cadherin on the prognosis of Stage I-II non-small cell lung cancer (NSCLC) was investigated. Tumor E-cadherin expression and its correlation with the clinical and morphological characteristics of a patient, as well as the prognostic role of this marker were studied. It was ascertained that the E-cadherin expression did not depend on patient gender and age, tumor histological pattern, location, grade, and pT category, but it was significantly related to the pN1 category (p < 0.

[Surfactant replacement therapy increases life-span of patients with acute respiratory distress syndrome].

The aim of the study is the evaluation of the influence of surfactant replacement therapy on the life-span of patients with acute respiratory distress syndrome (ARDS) in fatal cases. It has been determined, that in patients, were died from ARDS, exogenous surfactant therapy increases life-span from the moment of establishing of diagnosis of syndrome to fatal outcome. The initial functional state of lungs does not influence on life-span of patients with ARDS, but administration of exogenous surfactant is the important predictor of its increase.

[The influence of microvessel density in the tumor on the prognosis in patients with stage I-II non-small cell lung cancer after surgical treatment].

A study of the prognostic role of microvessel density in tumors of patients with stage I-II non-small cell lung cancer (NSCLC) was performed from June 2008 to June 2011. Determination of microvessel density using the marker CD31 was conducted in 114 patients. Microvessel density was significantly correlated with tumor size: so at greater than 3 cm in diameter, the content of microvessels was 68.

[Clinico-morphological substantations of parenchyma-preserving operations performance in surgery of chronic pancreatitis].

There was presented a comparative analysis of the surgical treatment results of 86 patients, suffering chronic pancreatitis, in whom resection and parenchyma-preserving elaborated operations were done, aimed for pancreatic and biliary ducts hypertension elimination. According to histological and histochemical data obtained, there are uniform changes, localized in pancreatic head, corpus and tail: the extended periductal fibrosis with the immune-cell infiltration foci and periductal connective tissue sheath formation. According to the immunohistochemical data obtained, in a fibrous zone there was obtained a big quantity of activated alpha-SMA-positive collagen producing star-like cells and a significant expression of a type IV collagen.
