[Influence of Gentiana lutea L extract on blood coagulation].

The dry extract from the terrestrial parts of Gentiana Lutea was received in accordance to the developed by us general technological scheme. Study of the pharmacological influence of obtained extract on the coagulating properties of blood revealed that after its per os instillation into experimental animals the time of the formation of active thromboplastin reliably increases, while the time of thrombin and fibrinous cluster formation is shortened in comparison with those indices in the animals, that did not receive phyto-preparation, at the same time morphological appearance of the peripheral blood remains unchanged. Dry extract of terrestrial parts of Gentiana Lutea prepared in accordance to the technology recommended by us, together with widely known pharmacological effects, is characterized with new activity - influence on haemostasis. Obtained preliminary data concerning influence of the extract on coagulation of the blood request further deep studies of its mechanism. Revealed new activity of the terrestrial parts of Gentiana Lutea and the studies of the mechanism of its activity will serve in future as a basis for the recommendation of its use in new nosology. Terrestrial parts of Gentiana lutea L. are proposed as an alternative of the underground parts of the plant. Alongside with that, it is expedient to continue the studies devoted to the development of the haemostatic remedies of plant origin with systemic and local action (sponges, films, skin glues) from terrestrial parts of Gentiana lutea L.

[Experimental investigation of general toxiology of antioxidant eyedrops davicol].

Authors examined the toxicity of antioxidant eye drops--davikoli. Antioxidants play important role in protecting the body from the formation of very dangerous substances referred to as free radicals. On the basis of honey an eye drops with high antioxidant activity--davicoli has been developed. The ocular effects of eye drops have been measured in a placebo-controlled double-blind study in 44 mice, 44 rats, 40 sea pigs and 20 chinchilla rabbits. Preclinical study revealed that eye drops davikoli are safe and non-toxic. During the investigation anti-inflammation features of eye drops davicoli was discovered.
