Diagnostic Signs

The following paper considers aspects of systematic and ecological structure of the weed medicinal plants growing in the biosphere reserve Pribuzhskoye Polesye. The studied weed plants of the region are considered to be used in pharmacology and medicine. Therefore, a detailed study of environmental groups and economic importance of commensal medicinal plants can serve as a basis for new trends development in resource studies of medicinal plants. The paper identifies diagnostic signs, as well as similarities and differences of morphometric evidence. The collection of field data was carried out by reconnaissance of the terrain. The study shows that the territory of the biosphere reserve Pribuzhskoye Polesye is characterized by a rich species composition of synanthropic weed medicinal plants of 57 species growing in different habitats that can be used for the treatment of diseases of the gastrointestinal tract, circulatory system and respiratory system. It is necessary to use weed plants for medicinal purposes to increase the base of receiving biologically active materials of plants.

Nucleophilic Catalysis

An efficient method for N-acylation of amides is described using a pyridine ring as the internal nucleophilic catalyst to give imides in moderate to excellent yields. The methodology provides a facile, air insensitive, and environmentally friendly route to form diversified imide scaffolds, which exist widely in natural products and biologically active materials.

The Given

Abstract Gibberelline, prednisolon and benzpyrene stimulated the growth of Tetrahymena at the first interaction, while epinephrine did not. On a second exposure following upon the first 24 h treatment after a rest period of 6 h, epinephrine, too, developed a stimulatory action, and the other three molecules gave rise to a still greater increase in the growth rate. Obviously, imprinting effected by the first interaction accounts for a greater responsiveness to physio­ logical materials (hormones) also if these are indifferent in respect of the given function, and non-physiological, but biologically active materials can also give rise to imprinting in exposed target cells.

Considerable Loss

Abstract Eight cases of blastic lymphoid leukemia have been treated with myelokentric acid in crude form, because hypothetically in blastic lymphoid leukemia there is a deficiency of this material. The crude myelokentric acid was used because it was more easily obtained than partially purified material. Purification of biologically active materials by methods of extraction and precipitation necessarily results in a considerable loss of material. Thirteen partial remissions occurred following the administration of crude myelokentric acid. Seven of the 8 patients have died, and 5 necropsies were performed. The necropsy material adds further weight to the belief that the remissions were induced by the myelokentric acid in that in all 5 necropsies there was a definite alteration in the histologic morphology as contrasted with the findings in the necropsies of the controls. It seems inadvisable, however, to treat a large number of patients with this material because it is crude, it is relatively unavailable, and no standard dose has yet been devised.
