[The immunomorphology of the mucosa of the bronchi and gastroduodenal zone in children with combined disease of the bronchi and gastrointestinal tract].

Mucous membrane of the bronchi, antral zone of the stomach and duodenum were studied histologically, morphometrically, immunohistochemically and bacterioscopically in 47 children of 5 to 14 years of age with bronchial asthma (16 patients), obstructive bronchitis (12 patients), chronic pneumonia or chronic nonspecific bronchitis (19 patients). All these children had also gastroduodenitis. There was an increase of local production of IgE and enhanced degranulation of mast cells in bronchial mucosa and gastroduodenal zone in children with bronchial asthma and obstructive bronchitis.

[The incidence of detecting HB viral infection in the families of patients with kidney diseases].

A total of 33 families were surveyed with a view to determine the presence of viral hepatitis B markers in persons with diagnosed renal diseases. In all patients markers of hepatitis B virus infection (HBsAg, anti-HBs antibodies, anti-HBc total and IgM antibodies) were determined in the enzyme immunoassay. Those families in which examinees with renal pathology were found to have markers of hepatitis B virus infection exhibited a high level of contamination with hepatitis B virus.

[Tactics in using antibiotics in diffuse forms of chronic nonspecific pneumonia in children].

The authors provide the results obtained during many years of studying different aspects of antibacterial treatment of purulent endobronchitis in children with prevalent forms of chronic pneumonia. The study was attempted at the clinic for disease of childhood, I.M.

[Clinico-endoscopic and morphometric characteristics of gastric and duodenal mucosa in children with dermatomyositis].

A total of 53 patients with dermatomyositis aged 4-14 with the disease duration of three months to eight years were under observation. Twenty seven patients complained of stomach-ache, II felt pain during palpation, 30 lost appetite. Electrogastrography revealed disorders in bioelectric activity of the stomach muscles in 99.

[The morphometric and immunohistochemical characteristics of the gastric and duodenal mucosa in systemic lupus erythematosus].

Histological, morphometric, and immunohistochemical studies of biopsy specimens from the mucosa of the body and antral portion of the stomach, the bulb and descending portion of the duodenum were performed in 27 children with systemic lupus erythematosis (SLE) and in 12 with chronic gastroduodenitis. The inflammatory infiltrate from SLE patients was found to contain higher levels of young and mature fibroblasts than that from patients with chronic gastroduodenitis, mature fibroblasts being prevalent. The inflammatory changes in the gastric and duodenal mucosa were ascertained to be associated with the progression of SLE.
