[New allele of the COCHLEATA gene in pea Pisum sativum L].

Analysis with the polymerase chain reaction showed that the Khlorofill-4 pea Pisum sativum chlorophyll-deficient mutant with reduced stipules has an altered structure of the COCHLEATA (COCH) gene, carrying a new mutant COCH allele. The phenotype of the mutant was described in comparison with another form having reduced stipules (stipules reduced) and the control. Leaves of the coch mutant are smaller and have other proportions than in the control; stipules are absent from leaves of the first nodes and are narrow, bandlike, or spoonlike at later ontogenetic stages.

[Genetic control of fasciation in pea (Pisum sativum L.)].

The inheritance and manifestation of fasciation character in three fasciated lines of common pea Pisum sativum L. were investigated. All studied forms are characterized by abnormal enlargement of stem apical meristem leading to distortions in shoot structure.

[Fasciation in pea: basic principles of morphogenesis].

A study of fasciated pea Pisum sativum L. (Fabaceae) mutant Shtambovy in comparison with the wild type (Nemchinovsky cultivar) has shown that fasciation is a result of abnormal cohesion of axial or other structures which arise in a superfluous amount due to uncontrolled meristic processes. In some cases, the organs with the same number and position as in the wild type can be fascinated.

[Use of surgical biopsy of the kidney in the differential diagnosis of various forms of arterial hypertension].

To make a more precise diagnosis, kidney biopsy was performed in 17 patients with a severe course of blood hypertension due to a mild urinary syndrome. Taking into account the high risk of hemorrhagic complications in such patients, an operational biopsy was performed (in 13 patients in a open way and in 4 patients in a semiopen one). As a result of the histologic investigation of kidney bioptates, the diagnosis was changed in more than half patients.
