Abstract:
It is investigated actions of a rutan on synaptosomes of a brain of model rats with chronic alcoholic intoxication it is revealed that rutan slightly increases fluorescence, respectively a level of cytocindery calcium in comparison with control. Results show about the possible competition between rutany and a glutamate for a site of regulation of opening of ionic channels, possibility of application of a rutan as the exciting neurotransmitter at chronic alcoholic intoxication. At research of action of a gossitan on sinaptosoma of a brain of model rats with chronic alcoholic intoxication it is revealed that gossitan slightly reduces fluorescence according to the level of cytocindery calcium in comparison with control. Results show that a preparation gossitan don't compete with a glutamate for a binding site. Perhaps, their action is caused by interaction with ionic channels of NMDA receptors.

Abstract:
The experiment was conducted in the form of a randomized completely block design with three replications. The main pots were kept under irrigation (at 20%, 40% and 70% of field capacity along with a well watered control). The sub-pots contained three Achillea vermicularis populations (Kahak, Khalkhal and Semnan). The results showed that drought stress had significant effects on photosynthetic pigments, proline, soluble sugar contents and peroxidase activity, but drought induction. Moreover, population variations had a significant effect on chlorophyll a, chlorophyll b and peroxidase activity. Among all the measured samples, the Khalkhal population had the highest content of photosynthetic pigments, soluble sugars and peroxidase activity. However, the Kahak population had the lowest value of the mentioned traits instead of the latter trait. Meanwhile, the severe drought stress produced the highest peroxidase activity, carotenoid, proline, protein, soluble sugar contents. By contrast, the lowest values of the mentioned traits were achieved in well-water treatment. The highest chlorophyll a, chlorophyll b and total chlorophyll contents were observed in 70% FC, while the lowest were recorded in 20% FC. The Khalkhal population × severe drought stress produced the highest carotenoid, soluble sugar content and peroxidase activity, and also, Khalkhal population × moderate drought stress recorded the highest contents of phosynthetic pigments. Therefore, the Khalkhal population could be introduced as suitable Achillea vermicularis population in Iran.

Abstract:
This study was carried out at the research field of Tarbiat Modares University, Peykan Shahr, Tehran to determine the content and chemical compositions of essential oil from fennel fruits at full ripening stage. The essential oil of dried fruits was extracted by hydrodistillation method using Clevenger apparatus, and analyzed by GC and GC-MS. The essential oil content of fruits was 1.1% at full ripening stage. The main oil components were trans-anethole (53.51%), carvacrol (11.93%), fenchone (8.32%), and timol (8.11%).

Abstract:
This work considers the problems of paleogenetics, archeology and antropology connected with mesolithic site Yuzhniy Oleni Ostrov and early migration of Y-DNA R carriers. Some hypotheses of the repopulation of the North Eurasia after the glacial age are considered, especially those connected with the ancient populations of the Onega lake shores. The hypotheses are matched and compared with the new paleogenetic data. New accents on existing hypotheses are formulated. The main peculiarities of the paper are taking into account of the hypothesis of A. Romanchuk of the Eastern Eurasian origins of Sino-Caucasian language family and the interpretation of ancient Y-DNA R1a1 presence in the Yuzhniy Oleni Ostrov site. The possibility of sino-caucasian/enissean language attribution of prehistoric languages of the North Eurasia and the Central Asia region is also discussed.

Abstract:
Abstract The results showed, the increasing ratio of radiant energy only at the expense of the aftereffect of organo-mineral fertilizers amounted of 0.21 and 0.33 %, which is allowed to accumulate the accumulation of dry biomass of soybeans for the period of two rotations of the sugar beet crop rotation, respectively, and 19.1 11.8 t/ha, respectively, 25.6 43.7 % more than in control. Thus, the greatest absorption of PAR by soybean plants (1,08 %) with assimilation surface of the leaves 44.0 thousand m2/ha, the photosynthetic capacity 2,640 million m2/day/ha of working productively at 2.44 g/ m2/day is marked on the variation, the organo-mineral fertilizers (background + straw 4 t/ha + manure 60 t/ha) in the second crop rotation, which allowed to establish the yield of dry biomass of 63.1 kg/ha.
