[Effects of T-activin in viral myocarditis in animal experiments]. / Vliianie T-aktivina na virusnyi miokardit v éksperimente.

The efficacy of immunomodulating agent T-activin has been studied in adult BALB/C mice infected with Coxsackie B1 virus. Optical, electron microscopic and immunological tests have shown that T-activin protects myocardium and modulates immune disorders in mice with viral myocarditis.

[Function of the gastric immune apparatus in duodenal peptic ulcer patients from the standpoint of age]. / Sostoianie immunnogo apparata zheludka u bol'nykh iazvennoi bolezn'iu dvenadtsatiperstnoi kishki v vozrastnom aspekte.

Results of immunomorphological studies carried out on 48 stomachs resected for duodenal ulcerous disease are reported. Mucosal inflammation described as "immune" and varying in degree in an age-related manner (being lowest in patients aged over 60) was noted in the pyloric part of the stomach. It is shown that the immune inflammation of gastric mucosa in duodenal ulcer patients is mediated by humoral immunopathological mechanisms involving, essentially, locally produced antibody, although delayed-type reactions are also possibly implicated.
