[The cytological diagnosis of liver cancer].

A study is presented of 96 patients with primary cancer of the liver. Hepatocellular cancer was diagnosed in 54 patients, cholangiocellular--in 36, low-differentiated--in 6 patients. Hepatocellular cancer was characterized by an increased size of the cells while they maintained likeness with intact liver cells, were characterized by significant anisocytosis, hyperchromia, reticular cytoplasm.

[Ultrastructural changes in neutrophils and anaerobic microorganisms during their interactions in experimental acute intestinal obstruction].

The authors established that 12 h after development of acute obstructive ileus in inactive neutrophil granulocytes (NG), the anaerobic microorganisms were intact, or at the process of division; in the active NG, they were destroyed, or when forming "halo", might preserve and migrate in the matrix of NG. In interaction of NG with microorganisms, the numerous oval and roundish bacterial bodies with a diameter of 0.2-0.

[Ultrastructural features of virus infected hepatocytes in patients with pathology of the hepatobiliary organs].

In electron-microscopic study of the puncture biopsy material in 52 patients with diseases of the hepatobiliary organs in 22% of cases, the liver contamination with the viruses was revealed. They caused destruction of hepatocytes and induced their appearance in the cytoplasma and mitochondria of the protein crystalline inclusions. This was of certain diagnostic and, perhaps, lithogenic importance.

[Long-term results of treating acute erosion and ulcer of the digestive tract].

The authors studied results of treatment of acute erosions and ulcers of the digestive organs that developed in 43 patients after different operative interventions. Twenty-one patients developed uncomplicated erosions and ulcers, 20--complicated hemorrhages and 2--perforations. Follow-up terms--from 1 to 7 years.
