[Biochemical aspects of growth-stimulating effects of steroid phytohormones on lupine plants].

Presowing treatment of seeds of lupine of various species and cultivars with brassinosteroids--homobrassinolide and epibrassinolide--caused an increase in protein content and a change in the proportion of some amino acids. Both hormones increased heterogeneity of high- and medium-molecular-weight nonhistone chromatin proteins but had no effect on the polypeptide profile of histones. Using epibrassinolide as an example, we showed that the brassinosteroid-induced increase in protein content in lupine seeds was due primarily to accumulation of the low-molecular-weight components of beta-conglutin.

[Arrangement of specialized public health care and the work experience of the gastroenterological center].

Arrangement of consulting gastroenterological centers at multi-type clinical hospitals makes it possible to render highly qualified medical care for adults, establish schools for training patients, render significant methodical assistance to medical staff on a permanent basis, especially during the period of the public health care system reorganization.

[Current principles of treatment of acid-dependent diseases].

The paper reviews current treatments of acid-dependent diseases. The role of hydrochloric acid hypersecretion in pathogenesis of some gastroduodenal diseases is shown. Efficacy of antisecretory drugs from different groups is compared.

[Peculiarities of embryonal development in vitro of Brassica napus pollen grains].

Literature data concerning the problem of the embryogenesis in microspore cultures of Brassica were reviewed. The influence of stress factors on the microspore cultures was examined. The some cytological and morphological peculiarity microspore entering in the embryogenesis developmental pathway were described.
