Introduction
In recent years we have observed that there are been more and more studies and increased reg- ulatory action regarding animal, plant and mineral-based raw materials, drugs, biological prod- ucts, groceries and food products.Therefore, dehydrated cow bile liver hydrolisate appears less harm- ful for the human body and may minimize damage to liver cells, have regenerative and healing properties, and may support the healing / recovery process process. It is important to find and apply preparations that work against acute inflammation of the liver protein, fat and carbohydrate me- tabolism. Pharmacological research was undertaken with the performance of a histomorphological assessment with reference to the hydrolisate liver, dehydrated cow bile, silymarin 3 with a composi- tion containing “Sillichol”, determining how it seriously affects the inflammation of the liver operation.
Goal: To determine the presence of the liver tissue morphology with reference tothe investigational
/ experimental new drug “Sillichol”.
Material and Methods: Male Wistar rats, specified as pathogen-free, weighing 200-250 g, were
obtained from the Vivarium of the Department of Pharmacology, Drug Research Institute, and
were used for the chronic CCL -induced liver injury model in all experiments. Eighteen rats were di-vided into three groups (with each group consisting of 6 rats).The rats were sacrificed at the end of the 14 days of the investigation, and the livers were im- mediately removed (Methods R.Virchow). Liver slices were made from a part of the left and cen- tral lobes, and immediately fixed in 10% buffered formalin phosphate solution, embedded in par- affin, and cut into 5μm sections. Subsequently, the sections were stained with hematoxylin and eosin (H&E) and observed under a microscope to evaluate histopathological changes (20x20).
Result: Liver tissue sections of the rats were stained with H&E. The histopathological assessment in the livers was performed for all groups. Rats in the negative healthy group exhibited normal, well- defined histological structures, without any signs of vascular or inflammatory changes: no cavita- tions, necrosis or fibrosis were found in normal control sections.
The histopathological analysis of the livers revealed signs of toxicity after administration of CCl .This toxicity was significant in comparison with the control group and cavitations, fibrosis in board ar-
eas, mild vascular congestion and moderate inflammatory changes with congested sinusoids, nu- clear changes, and centrilobular necrosis. Sinusoids spaces were flooded with inflammatory cells.
The Sillichol-treated animals of the experimental group showed a complete reversal of toxic ef- fects in the liver cells; no necrosis was seen. The central vein and portal triads appear normal and show an increase of Kupffer cells. Some of the hepatocytes indicated binucleation, suggesting re- generative activity with feathery degeneration of hepatocytes.The Carsil-treated animals of the standard group: The histology of the liver sections in rats adminis-
tered with Carsil indicated significant improvement with less damage of liver tissue, as indicated by a reduced level of necrosis, narrow fibrotic septae, fat storing cells, Kupffer cells, and narrow cavita- tion.
Conclusions
We found that the “Sillichol” biological active product treatment reduced hepatic necrosis and fibro-cal active product improved the regeneration process of liver cells, helped to normalize cell struc-
ture, and had an effect on the anti-inflammatory action in damaged liver cells.

Wistar nonlinear rats weighing 170-220g. Rats were divided 5 groups, including control group, group-1, group-2, group -3 and reference group. Dried thistle extract and raw bovine testicle were contained by 1:1, 1:2 and 2:1 ratio. Each 0.1g ratio was dissolved in 20 ml distilled water and administered 2 times per day. Blood sampling was done for each rat after 3, 7, 14, 21, 28 and 35 days. Their testosterone level was measured by ELISA Kit.
Results: The results indicated that free serum testosterone level in male rats increase and decrease in 7 days frequency. All tested groups showed gradual increase in the level of free serum testosterone when compared to that of corresponding control (p<0.05). Statistical comparison of all groups revealed that the maximum level was found in group 1. Moreover, group 3 was showed gradually increase in level of free serum testosterone, irrelative with period of decrease testosterone level.
Conclusion: According to our results and previous study, it is suggested that preparation with Tribulus terrestris L. extract could be used in the androgen deficiency and erectile dysfunctions.

Introduction: Pathologies of hair growth can be psychologically distressing but they are poorly controlled. Hormones and paracrine factors regulate the hair follicle and its associated glands. However, our understanding of their mechanisms is limited, restricting the development of new treatments for hair disorders. Therefore better treatments for hair loss disorders are required. Some plant extracts are believed to have effect on hair growth. Urtica Cannabina L and other are used traditionally as stimulators of human hair growth, but their effects on hair growth in vivo has not been studied yet.
Goal: The aim of this study was to investigate the actual effects of those local plant extracts used as a traditional herbal treatment for hair loss, using in vivo mouse model; and to compare their effectiveness with the best medical treatment available.
Material and methods: Effects of extracts from Urtica Cannabina L, and Glycyrrhiza uralensis Fisch both prepared separately and mixed at recommended concentrations. Experimental groups were compared with standard (positive control) and negative control groups. Shaved back of Balb/c mice (4 weeks old) were treated daily for 28 days (four groups, n=6 per group), and degree of their effectiveness was observed and compared with each other and with both of positive and negative control.
Results: show that mixture of the two herbal extract have similar significant hair growth promotion effect compared with other groups and negative control. Therefore, extracts stimulates rodent pelage follicles in vivo, thus possible to use as promoter of hair growth.
Keywords: Urtica Cannabina L, Glycyrrhiza uralensis Fisch, hair follicle, hair loss, mice.

The world pharmaceutical market will reach nearly USD 1,200 billion by 2016, an increase from the USD 956 billion recorded in 2011. The 10 largest drug companies control over one-second of this market. The drug companiesinvestinhigh cost of promotion, and it uses a variety of promotional strategies to influence physicians’ prescribing decisions. Within this context, medical representatives are the key personnel employed in promoting their products. For example in the USA, drug companies spend $54.5 billion on marketing promotions and they spent more than US$10 billion on representative cost. In Mongolia, medical representatives of foreign countries are increasing over the years. So doctors and pharmacists often receive medicine information from medical representative. But the research about medical representative influence on physicians is not observed. The purpose of the study is evaluating pharmaceutical marketing promotions tended to family health centers/clinics physicians. Random sectional, organized based survey with questions was carried out of physicians of the family health centers/clinics. SPSS-20 and Microsoft office excel programs were used to colligate and processing information. Result, discussion: In 2012 the Libya, an anonymous survey questionnaire was circulated to 1,000 Libyan doctors in selected public and private practice settings in Tripoli, Benghazi and Sebha. A questionnaire return rate of 61% (608 returned questionnaires) was achieved. Most respondents (94%) reported that they had been visited by medical representatives at least ‹once› in the last year. Fifty per cent of respondents met with medical representatives at least once a month, and 20% at least once a week. In 2010 the Germany, 100 physicians in each of three specialties (neurology/psychiatry, general medicine, and cardiology) were surveyed with a questionnaire containing 37 questions. 208 (69.3%) questionnaires were anonymously filled out and returned. The result was 77% (n = 160) of all physicians were visited by PSR at least once a week, and 19% (n = 39) every day. In this study, an anonymous survey questionnaire was circulated to 100 physicians of the family centers/ clinics. A questionnaire return rate of 99% (99 returned questionnaires) was achieved. Most respondents 100% reported that they had been visited by medical representatives at least once in the last years. 55.5% of respondents met with medical representatives at least once a month, so 24.2% at least once a week. So 76.8% questionnaireswere satisfied after having representative meetings are informative, advertising and information include equally among 57.2 questionnaires had complete answers. Conclusions • All respondents met with medical representatives at least once a month. • Content of representatives meetings are equally adverting and informative so it influences positively to them. • 61.2% questionnaireswere satisfied after having representative meetings.
