The studies of M. Colombo (1989) and W. Lange (1992) showed that 30~40% of people became chronic after suffering from hepatitis B virus (HBV) and C virus (HCV) infection, and about 50% of the chronic cases transformed into primary liver cancer. There have been few studies done in Mongolia on hepatitis infection among health professionals, particularly in nurses. In a study done by Chimedsuren (8), the study showed that 19.4% of people with identified surface hepatitis B antigen (HBsAg) and antibodies to hepatitis C virus and 8% of people with the identified nucleotide of RNA for the hepatitis C virus (polymerase chain reaction) had an acute form of hepatitis C. Studies on the hepatitis virus genome damaging effect on liver cells showed that genotype 8 (A, B, C, D, E, F, G, TTV) had the most damaging effect on liver cells (Hahn and Faeka, 2007). Several studies have shown a relationship between hepatitis B virus infection and a lack of compliance regarding safety regulations and rules by medical personnel. Results of a study from the Maternal and Child Health Research Center showed that tests done to detect hepatitis B virus antigen and antibodies to C virus did not reveal anything. Both antigen and antibodies in 69% cases did not show, and separately, B virus and antibodies to hepatitis C virus were identified in 13% and 9%, respectively. Results of the tests taken from health personnel in Shastin Central Hospital showed that in 76% of the cases, the B virus antigen with C virus antibodies was not identified. In 8% of the cases, the B virus antigen was present on its own. The combination of B the virus antigen and C virus antibodies were present in 8% of nurses and doctors, respectively. 82% of the cases had negative results for the detection of a combination of B virus antigen and C virus antibodies taken from health personnel from the State Central Clinical Hospital whereas the B virus antigen and C virus antibodies by themselves were present in 7% and 14% of the cases, respectively. Combined cases of the B virus antigen and C virus antibodies were identified in 4% of the personnel. Results of the tests taken from the health personnel in the Hospital of the Ministry of Justice and Internal Affairs showed that in 79% of the cases, the B virus antigen with C virus antibodies were not identified. Separately, the B virus and antibodies to hepatitis C virus were identified in 8% and 13% of the cases, respectively.

<P>Purpose: We examined whether and how Sac-1004, a vascular leakage blocker, would restore erectile function in an animal model of diabetic erectile dysfunction. Materials and Methods: Eight-week-old C57BL/6J mice were used. Diabetes was induced by intraperitoneal injection of streptozotocin. Eight weeks after diabetes induction the animals were divided into 6 groups, including controls, diabetic mice that received repeat intracavernous injections of phosphate buffered saline (20 mu l) on days -3 and 0, and diabetic mice that received repeat intracavernous injections of Sac-1004 on days -3 and 0 (1, 2, 5 and 10 mu g, respectively, in 20 mu l phosphate buffered saline). One week after injection erectile function was measured by cavernous nerve stimulation. The penis was then harvested for histological examinations and Western blot analysis. Results: Local delivery of Sac-1004 in the corpus cavernosum restored erectile function in diabetic mice. The highest erectile response was noted at a dose of 5 mu g with a response comparable to that in the control group. Sac-1004 significantly increased cavernous endothelial and smooth muscle contents, and induced endothelial nitric oxide synthase phosphorylation (Ser1177). Sac-1004 decreased extravasation of oxidized low density lipoprotein by restoring endothelial cell-cell junction proteins and pericyte content. Sac-1004 also promoted tube formation in primary cultured mouse cavernous endothelial cells in vitro. Sac-1004 mediated cavernous angiogenesis and erectile function recovery was abolished by inhibiting angiopoietin-1-Tie2 signaling with soluble Tie2 antibody. Conclusions: With the effects of angiogenesis and antipermeability Sac-1004 reestablishes structural and functional cavernous sinusoids. This is highly promising for future treatment of erectile dysfunction from vascular causes.</P>

Aims: M.Colombo, W.Lange studies showed that 30-40% of people become chronic after suffering from-Hepatitis B and C virus, about 50% chronic cases transformed into primary liver cancer. There are a few studies in our country were conducted on hepatitis among health care professionals, particular nursing personnel. The study was conducted to identify of hepatitis B and C virus among nurses and make recommendations to prevent and control of hepatitis B and C virus infections. Methods: We carried out cross-sectional study among selected nurses to determine surface antigen of hepatitis B virus and antibodies to hepatitis C virus. For identification of these antibody and antigen and validation of results ELISA tests from CTK, Biotech company (USA) and simplifying diagnostics were used. Results: There were 598 nurses from the First Central hospital, the Second Central hospital, the Third central hospital, Railway Central hospital, Hospital Ministry of Justice and Internal Affairs and National Center of Maternal and Child Health who participated in the study. From 5 hospitals 598 nurses surveyed and revealed the hepatitis B virus surface antigen positive 18.9%, hepatitis C virus antibodies in 23.1%, co-infection of hepatitis B and C were detected 1.2%. There is an urgent need to provide knowledge to medical personnel regarding standards during the procedures, concerning hepatitis infections monitoring and improve technology used during procedures. Conclusions: The study identified that 43.2% of nurses surveyed on hepatitis B and C viruses were detected . It shows a high prevalence among the nurses in Mongolia.

This paper describes the design of an X-band dielectric resonator oscillator(DRO) based on a pseudomorphic high electron mobility transistor(pHEMT). DRO’s are widely used as a local oscillator for their high stability. In this paper, we realized a DRO employing a pHEMP with high efficiency and stable output, a series-coupled dielectric resonator, input and output matching circuits, a frequency-tuning plate, and a metallic cavity. The transistor’s instability is increased by adding a capacitive impedance at the source of the pHEMT. Starting from the initial design based on the oscillators small signal model, an optimum design of the oscillator is obtained using a CAD tool. The designed oscillator is fabricated and tested. The fabricated oscillator shows a stable oscillation with 1.5-4.5㏈m output at 10.5-10.9㎓.
