[The immunity during the pre-clinical period of type I diabetes mellitus].

The purpose of the study was to investigate the condition of immunity (blood lymphocyte immune phenotype and ultrastructure) in healthy children with a family background of type 1 diabetes mellitus (DM 1) having or not having diabetes-associated autoantibodies (DAAB). The subjects of the study were divided into three groups. Group 1 consisted of 90 children with a family background of DM 1 (first line relatives had DM 1), DAAB- (GADA, IA-2A, and IAA) positive or negative; group 2 consisted of 51 children with newly revealed DM 1; group 3 included 45 healthy controls, normoglycemic DAAB-negative children with no family background of DM 1.

[Electron microscopy and ultracytochemistry of lymphocytes containing Gall bodies in the blood of patients with diabetes mellitus, Hodgkin disease and clean-up workers of the Chernobyl Atomic Electric Plant accident].

Submicroscopic and ultracytochemical changes in lymphocytes containing Gall body complex in the cytoplasm, have been studied in the blood of patients with type 1 and 2 diabetes mellitus, Hodgkin disease, and clean-up workers of the Chernobyl accident. It has been shown that each pathological state was characterized by specific changes in the ultrastructure of Gall body complex, that pointed out its important role in the function of this type of lymphocytes and may be used as an additional cytological criterion in the estimation of T-immunity status.

[Electron microscopy and ultracytochemistry of blood lymphocytes containing Gall bodies in healthy individuals].

The authors have conducted electron microscopic and ultracytochemical studies of blood lymphocytes of healthy individuals containing Gall bodies (GB) which are typical for CD4+ cell subpopulation. It has been established that GB have quite a complex submicroscopic structure and together with its derivates, granules-satellites, as well as mitochondria, microfilaments, rough endoplasmic reticulum canaliculi, and Golgi complex it forms a unique active functional complex. GB show a high activity of acid phosphatase and positive reaction to glycogen.
