This study was performed at Hanoi University of Natural Sciences and National Institute of Malaria and Parasitology from April 2001 to May 2002. Biological trials on laboratory strains of An. dirus were carried out according to WHO/VCB/81.806; WHO/CDS/CPC/MAL/98.12 and WHO/VCB/89.981. Analyses were conducted by the method of fluid-fluid extraction with the solvent system of n-hexan. Fendona 10SC,Icon 2,5CS,K-othrin ISC, Imperator 50EC .soaked mosquito bednet had manifested insecticide effect. Their effect of killing An.dirus was maintained for 5 -6 months. The procedure of analysis of pyrethroide compounds in use for soaking mosquito bednet was established and the half live of 125-188 day long period for each compound was determined

A cross-sectional study was conducted in HCM City in April-May 2004 on 600 men who have sex with men (MSMs) in order to identify the risk factors of HIV transmission for elaborating a specific interventions .

Medicine in the Northern provinces on the laboratory biosafety, authors showed that in 82%of facilities, there are adequate ventilating space,in 92,8% there are ceilings and walls made by suitable materials,in 98%,there are proper laboratory coveralls, uniforms and gloves. However,in 83%, laboratory biosafety management and indoor regulations were not complied with strictly; there are not clearly biohazard warning signs, in 57% of facilities there is not any processing system for draining waste water flow. 75% of supervisors were not properly trained on biosafety

On 138 serum samples taken in the first 7 days of acute syndrome of brain, by MAC-ELISA technique 95 samples were determined as positive, 68.84% was positive. 43 samples taken in the first 7 days of the disease there was no detected antivirus IgM antibody but this could not concluded as negative, but may be a late antibody response or may be another cause of acute brain syndrome. For assuring the accuracy of the diagnosis, the samples taken in the first 7 days of the disease must be taken again after 7 day to verify the results.

Living donor liver transplantation - achievement in some great Asian centres as follows: There were 306 cases of liver transplantation for 292 patients at Queen Mary Hospital, Hong Kong Medical College, from October 1991 to September 2003; There were 148 cases of living donor liver transplantation at Chang Gung Memorial Hospital, Kaohsiung, Taipei from June 1994 to October 2003; There were 227 cases of living donor liver transplantation at Tokyo Medical Centre, Japan, from Jan. 1996 to June 2003; In 2002 there were 127 cases of living donor liver transplantation at Asan Medical Centre, Seoul, Korea. Living donor liver transplantation technique was made at some Asian Hospitals, mostly at Asan Medical Centre of Korea. It is different from european countries, most of liver transplantation in Asian were taken from the living donors

On white rats, high doses of paracetanol (2g/kg of body mass) and carbonetetrachloride (CCl4 –1.4ml/kg body mass administrated orally) increased dramatically serum transaminase AST and ALT, reduced liver capacity of cholesterol and total protein synthetizations. Granulous degeneration, lipid degeneration and necrosis focus were observed pathohistologically. Linh chi mushroom fluid extracts with the dose of 4g/kg of body mass reversed these biochemical indicators and restored nearly normally the damaged tissues. Similar results were obtained with the oral dose of 25mg Silimarin brand name preparation/kg body mass.

From 1995 to 2002, 364 courses of chemotherapy with different regimens, almost gave various side effects such as leucopenia, thrombocytopenia, hypohemoglobin, increase of liver enzymes (SGOT, SGPT,…), enhance urea, creatinine level, nausea, alopecia… with different severity and incidence. The common regimans with more significant side effects were Doxorubicin + AraC (P3), MOPP (P2), CHDP (P1) and VAD (P4); the regimens AraC + Depersolon (P7), Hydrea + AraC (P6) and particularly Hydrea alone (P5) gave usually less side effects

At Cho Ray Hospital – Ho Chi Minh city from Dec 2001 to Dec 2002, 228 heart failure cases (96 males, 130 females, aged 58.4317.45) were studied. Their associated conditions were: 14 with diabetes, 5 brain blood infactus, 5 hyperthyroidies, 19 kidney failures. Among 162 patients with electrolyte disorders, 25 were died, the rate of hyponatremia and hyperkalemia was significantly higher in fatal group than in survival group. Hyponatremia was fatal risk factor and it should pay great attention to treat this condition with hypertonic natrium solution
