Radiationless deactivation of the excited phototautomer form and molecular structure of ESIPT-compounds.

Correlation between the character of electronic density redistribution in the excited normal and phototautomer forms, which are involved in the excited state intramolecular proton transfer (ESIPT) reaction, and the rates of primary photoprocesses--proton phototransfer and radiationless deactivation of the phototautomer form--was analysed on the qualitative level. It was revealed that noticeable improvement of fluorescence properties of ESIPT molecules could be achieved by directed modification of their chemical structure, most importantly by the introduction of electron withdrawing substituents into their proton donor moieties. Several facts are presented in favour of the last statement.

[Hypoglycemia and epilepsy syndrome in diabetes mellitus in children].

Eight children suffering from diabetes mellitus and epilepsia were followed up. Emphasis is laid on the necessity of measuring glycemia in diabetes mellitus patients during convulsive attacks as well as on the importance of early diagnosis of epilepsia to institute multimodality treatment.

[Comparative evaluation of the lipid metabolic indices of children with a hereditary predisposition for diabetes and in manifest diabetes mellitus].

The paper is concerned with the results of investigation of serum lipid, phospholipid and lipoprotein spectra in 31 sibs, 100 children with diabetes mellitus (DM), 83 women in birth with DM and their fetuses. This study showed a necessity of planned investigation of sibs not only for the detection of glucose tolerance but also of primary and secondary dyslipemia. In children with manifest DM the ratio of lipid, phospholipid and lipoprotein fractions was disturbed and depended upon a degree of compensation, a period of disease and a dose of insulin.
