[Subtotal leiomyomatosis of the esophagus and proximal part of the stomach].

Generalized leiomyomatosis of the esophagus and stomach is a rare disease. According to literature data, age of the patients ranges from 9 to 84 years, in men this disease is diagnosed 2 times more often than in women. It is necessary to differentiate this disease with cancer, esophageal diverticulum, achalasia of the cardia, hiatal hernia.

[Effects of some growth factors and cytokines on ATP synthesis by plasma-membrane-enriched particles isolated from different human tumors].

Plasma-membrane-enriched particles isolated from the tissues of malignant tumors of different sites are shown to accumulate ATP under the influence of polypeptide growth factors and cytokines whose receptors have a tyrosine kinase activity. Polypeptide growth factors, such as EGF, FGF, NGF, TNF, insulin, and the cytokine IL-2, were studied on the accumulation of adenosine-5'-triphosphate (ATP) by the preparations of plasma-membrane-enriched particles isolated from the target tissues of human malignant tumors. The tumor (transformed) cell plasma membranes of the lung, bowel, stomach, pancreas, as well as the cells of neurinoma and a retroperitoneal extra-organ malignant tumor (leiomyosarcoma) are demonstrated to be able to synthesize ATP from inorganic phosphate and ADP under aerobic conditions human with the participation of the cyanide-insensitive proton phoric NADH-bound transversely oriented chain.

[Use of ceftriaxone in the prevention of postoperative purulent complications after surgery on the stomach and small intestine].

Ceftriaxone was administered intravenously in a single dose of 1.0 g 15 minutes prior to surgical intervention for peptic ulcer and gastric or duodenum tumor in 31 patients at the age of 33 to 74 years. In all the patients primary adhesion of the surgical wound was recorded.

[Clinical features, diagnosis and treatment of benign nonepithelial tumors of stomach].

The results of treatment of 24 patients with benign nonepithelial tumors of the stomach (BNTS) are presented. The majority of the tumors were leiomyomas (42%). The preoperative diagnostic algorithm included x-ray examination of upper gastrointestinal tract, endoscopic examination with histologic study (biopsy), ultrasound examination and CT.
