IntroductionNumber of kidney acute and chronic disease is increasing rapidly in the world and becoming the majorcause of death even population employment capacity is invalid. Statistical report of Mongolian Ministryof Health last 5 years statistic kidney disease is in the 3rd of non-contagious disease Synthetic andchemical medicines used for this sort of disease would have side effects in some cases. Plants, animalsand minerals biologically active substances, side effects need to produce new drugs, has attracted theattention of researches.GoalIdentifying pharmacology act of new granule medicine preparation.Material and Methods: The effects of the medicinal substances were investigated on “WISTAR” linesof white rat. Pathological model of nephritis was formed by injected the rats with kanamycin sulfate(Mondodoev.A.J, Lameza.S.B, Bartonov.E.A, 1988). The experimental animals were given any of thenew granular herbal medicine and compared to the rats given Nefromon. After treatment the creatinine,urea acid and MDA in the serum were determined. MDA is identified by an amount of concentration andmethod (Stalinaya. I.D. 1977).ResultCreatinine amount of disease model group of kidney illness created by kanamycin sulfate is comparedwith healthy group animals and 1.64 times, carbamide amount is 4.25 times, rest of the azote’s 2.73are increased and comparing the experiment group creatinine amount is 1.65 creatinine amount is 1.65decreased comparing with disease model group.ConclusionWhen compound ingredients preparation creates experiment animal kanamycin sulfate oxidantdominates, intensify the kidney cell active, decrease the carbamide and creatinine and decrease thekidney cell necrosis.

Conclusion The results from this study, there was shown differences in bioactive substance of each sorts, overall content of tannin July to August, total flavonoid May to July, and antioxidant activity in June, were high.

Background: Lower extremity arterial diseases are chronic stenosis of the artery and occlusive arterial diseases, which are commonly caused by atherosclerosis. Prevalence of lower extremity arterial diseases has positive proportional relationship with age of the patients. Furthermore, prevalence of lower extremity arterial disease is 16% among the males over the age of 60, whereas prevalence among same aged woman is 13%. Among the age group of 38 to 59 age, 60 to 69 age and 70-82 age group, prevalence of lower extremity arterial disease was 5.6%, 15.9%, and 33.8%, respectively. Goal: Identifying lower extremity arterial occlusive disease and chronic stenosis of arteries by CTA-TASC classification of aorta-iliac and femoral popliteal lesions. Obiective:
1. To identify age and sex of the patients with lower extremity arterial occlusive disease and chronic stenosis of arteries.
2. To identify lower extremity arterial occlusive disease and chronic stenosis of arteries by CTA-TASC classification of aorta-iliac and femoral popliteal lesions. Material and methods: Study sample consisted of 237 patients, who were diagnosed with lower extremity arterial occlusive disease and chronic stenosis of arteries from 2019 to 2020 at reference centre on Diagnostic Imaging na after R.Purev State Laureate, People’s physician and Honorary professor of the State Third Central Hospital. Computed angiogram images of lower extremity arteries were examined. Contrast agent “Ultravist” was pumped by automatic syringe. Lower extremity arterial occlusive disease and chronic stenosis of arteries are categorized by CTA-TASC classification of аorta-iliac and femoral popliteal lesions. The youngest participant was 20 years old and the oldest participant was 76 years old. Common statistical measurements such as means and standard errors were calculated. Probability of results were checked using Student’s test. Results: We have found following results: 185(78.1%±3.0) cases out of 237 diagnosed patients with lower extremity arterial occlusive disease and chronic stenosis of arteries are males and 52(21.9%±3.0) cases are female. Distribution of lower extremity arterial occlusive disease and chronic stenosis of arteries by the age group of patients are: up to 20 years of age is 3 (1.3%±0.7), 21 to 40 years of age is 14(5.9%±1.5), 41 to 60 years of age is 86(36.3%±3.1) and over the age of 61 is 134(56.5%±3.2). It is statistically highly significant that experiencing lower extremity arterial occlusive disease and chronic stenosis of arteries among the age group of over 61(P<0.001).
The result of lower extremity arterial occlusive disease and chronic stenosis of arteries by the CTA-TASC classification of aorta-iliac and femoral popliteal lesions are: CTA-TASS аorta-iliac lesions A-16(6.8%±1.8), B-8(3.4%±1.2), C-12(5.1%±1.4), D-41(17.3%±2.5), CTA-TASS femoral popliteal A-41(17.29%±2.5), B-53(22.36%±3.6), C-47(19.83%±2.6), D-96(40.5%±3.2), respectively. Conclusions

2. Following two categories have identified more than the rest, 17.3% CTA-TASC classification of аorta-iliac lesions, type D and 23.3% CTA-TASC classification of femoral popliteal lesions, type D.

Background: The American Heart Association estimates that more than 1 million people die each year from acute coronary heart disease and half a million from acute coronary syndrome, and that $ 115 billion a year is spent on diagnosing and treating coronary heart disease [Word Health Organization, 2013]. Goal: In this study we aimed to using coronary computed tomography angiography (CCTA) to diagnose unstable plaques in coronary artery disease. Material and methods: From 2018 to 2021, we performed a coronary computed tomography angiography (CCTA) scan with a Philips Ingenuity 64-slice computed tomography (64 MD-CT) device and examined 47 patients diagnosed with unstable coronary artery disease at the Reference centre on Diagnostic Imaging named after R.Purev State Laureate, People’s physician and Honorary professor of the State Third Central Hospital.
Common statistical measurements such as means and standard errors were calculated. Probability of results were checked using Student’s test. Result: In studying signs of coronary computed tomography angiography (CCTA) to diagnose unstable plaques in coronary artery disease that coronary artery diameters more widening to compared healthy artery 16(34.0%±6.9), low density sites clarify in plaque (lower than +30HU)- 14(29.8%±6.7), small calcification detect in plaque 36 (74.5%±6.4), ring liked additional density (lower than +130 HU) sees in edge of plaque (Halo sign)-9(19.2%±5.8), plaque edge roughness, erosion liked changes- 18 (38.3%±7.1), rupture of intima (dissection)- 8(17.0%±5.5). Conclusion We detect that computed tomography angiography (CCTA)’s specific signs of unstable plaque of coronary artery disease are coronary artery diameters widening, low density sites clarify in plaque (lower than +30HU), small calcification detect in plaque, ring liked additional density (lower than +130 HU) sees in edge of plaque (Halo sign), plaque edge roughness, erosion liked changes and rupture of intima.
