Morphological and Immunohistochemical Features of the Heart under the Effect of Hydrogen Sulfide Balneotherapy.

The effects of hydrogen sulfide baths and sulfide-silt mud applications on the abdominal wall were studied in outbred white rats. Heart preparations stained with hematoxylin and eosin were analyzed and the mean numbers of cells expressing Ki-67, Nkx-2.5, and mesenchymal stem cell markers were determined.

[Morphological characteristics of Palatine tonsils candidiasis in the late stages of HIV-infection].

Candida lesion of Palatine tonsils was studied in 32 HIV-infected patients in the late stages of the disease using histological and cytological methods. There were used conventional methods during pathomorphological studies of palatine tonsils tissue fragments obtained by biopsy, and smears from the surface of the organ. It was found that micromycetes spp.

[LIPID PROFILE AND LIVER DISEASES AMONG PATIENTS WITH MORBID OBESITY].

Objectives: The aim of our study was to investigate associations between the lipid profile, liver condition and the level of BMI.

Methods: Our sample consisted of 58 patients: 30 - with morbid obesity and BMI - 40-49 (1 group), 28 - with superobesity, BMI - 50-69 (2 group). Lipids and hepatic functional tests were measured just prior to surgery.

[Neoangiogenesis and density of microvessels in breast carcinoma tissue].

The morphology of neoangiogenesis in breast carcinoma tissue is considered as a relationship between the density of the tumor vascular bed and different indices (age, histological type of a tumor, stage of the disease, tumor anaplastic proliferative activity, fibrosis degree, stromal cellularity, and parenchymal destructive changes).

[Age-related characteristics of breast invasive ductal carcinoma].

377 patients aged 30 to 79 years who had breast carcinoma were examined to study the age-related features of tumor anaplasia. The degree of tumor anaplasia was studied, in primary nodules, less and more than 2.5 cm in diameter in patients of different ages.

[Biophysical properties of bile and urine in patients with cholelithiasis].

The electric conductivity of the hepatic bile received during and 24 hours after surgery from the drainage introduced into the common hepatic duct was studied in 94 patients with cholelithiasis. It is demonstrated that conductivity increases in cholestasis, inflammatory process in the biliary tract and depends on the hepatic morphofunctional status. The specific electric conductivity of intraoperative bile that is more than 192 S/m is considered to be criteria for the diagnosis of cholangitis.

[Diagnosis of viral liver cirrhosis in the practice of the pathologist].

An autopsy observation of viral cirrhosis of the liver is presented. Along with the clinical data, morphological diagnosis of viral cirrhosis of the liver one should take into account not only the nature of cirrhosis (macronodular surface, multilobular structure of regenerative nodes, wide fibrous septae and lymphohistiocyte infiltration, Councilman bodies, "frosted vitreous" hepatocytes, mature lipofuscin in hepatocytes) but also the possibility of detecting HBsAg in paraffin sections of the liver stained with orseine and aldehydethionine.

[Morphological characteristics of acute viral hepatitis].

From the literature and their own observations the authors present morphological criteria of acute viral hepatitis which may be used for differential diagnosis from hepatites of other etiology (toxic, drug). Examinations of liver biopsies from patients with viral hepatitis permit to establish the stage of the disease and to predict its possible outcomes.
