Choleretic effects of the Mongolian medicinal plant Saussurea amara in the isolated perfused rat liver

Saussurea amara is used in traditional Mongolian medicine for the treatment of hepato-biliary disorders. To determine the plant's effect on the bile-salt independent bile flow (hydrocholeresis) as a measure of liver exocrine functions, different extracts were investigated in the isolated rat liver perfusion system. The methanolic extract (3) exerted a dose-dependent increase in bile flow (16%, 37%, 53%, 61%) in concentrations of 50 mg/L, 100 mg/L, 250 mg/L and 500 mg/L. The aqueous crude extract (1) and the ethyl acetate extract (2) also showed a dose-dependent increase, whereas at the highest concentrations (1000 mg/L and 100 mg/L, respectively) a continuous decrease in bile flow could be observed. Cynaropicrin also provoked a dose-dependent increase in bile flow, but caused liver damage at the highest dose tested (20 mg/L). Apigenin 7- O-glucoside, present in extracts 2 and 3, induced a dose-dependent increase of 20%, 30% and 40% (5 mg/L, 10 mg/L, 20 mg/L) and showed a significantly higher effect than the reference substance cynarin. The total flavonoid content was determined by spectrophotometry. To quantify the absolute amount of cynaropicrin in the crude drug and in the tested extracts, an HLPC system was established with santonin as internal standard.     

Results of Self-Sampling Methodology Impression for Cervical Cancer Screening in Mongolia

Objective:  Mongolia is a sparsely populated country; however, almost fifty percent of the population lives in the capital city. Medical care services and exceptionally well-organized cervical cancer screening tests are limited in remote areas. To improve cervical cancer screening test coverage, we compared the interest between physicians taking samples and self-sampling among the attendees in this study. Methods: A total of 175 women participated in this study. The hundred twelve women visited the Gynecology ward, and the sixty-three women were provided with the cervical self-sampling test kit and filled out a questionnaire. Subsequently, the acceptability of physician taking and self-sampling were evaluated using a questionnaire. All specimens were processed using the TACAS LBC system, and the quality of samples was tested by cytology. Results: Regarding the acceptability of self-sampling, the selections for subsequent screening were 36% self-sampling and 64% gynecologist-sampling methods. The acceptability rates were higher in the remote areas than the urban areas. However, 64% of the participants lacked knowledge that the causative agent of cervical cancer is the human papillomavirus, and 66.9% mainly were sexually transmitted. In addition, 82.3% of the women surveyed were unaware that there was a vaccine to prevent cervical cancer, but 88.6% wanted to be vaccinated. Of most women, 44.4% chose self-sampling due to no embarrassment in the gynecological examination. The self-sampling preferences were dominant in the old age group (61.6%). The cytology satisfaction rate in physician-sampling (99.1%) was higher than in the self-sampling group (69.8%). Conclusion: The Implementation of the self-sampling tool may be considered a primary screening. The self-sampling test can adopt into the early screening program and may increase the coverage of the screening program and improve the quality.
