Some new antimalarial water soluble derivatives of artemisinin were prepared by etherification of dihydroartemisinin with appropriate aryl alcohols. They are artelinat and metaartelinat. Influence of catalists and solvent on the etherification and the antimalarial activity of them as well as artesunat were studied.

By condensing azometines of vanilline and aromatic amines with acetophenon, synthesized 7 b-Aminocetones. The structure of obtained products have been characterized by elemental analyses and IR, UV spectroscopy. The compounds have been tested for antibacterial and antifungal activities. Result b-Aminocetone of vanilline have great effect in antibacterial and antifungal activities.

After 10 years of implementing the program of neonatal tetanus elimination from 1992 to 2001 in the Northern region, the tetanus toxoid coverage for pregnant and for child bearing age women have always been maintained at greater than 84%. The incidence of NT per 1000 live births has decreased, from 0.23 in 1994 to 0.07 in 2001. The disease has been eliminated at provincial level since 1995 and at district level since 1999.

Malposition tooth (etopic eruption tooth). Malposition tooth are abnormal eruption teeth in the jaw. It can be: transversion or not (labioversion and hard palate). There are many causes of large tooth and small jaw; supernumerary teeth; primary teeth exist too long; odontoma, cleft palate or cleft lip. Malposition tooth causes effect to function and esthetics

Studying retrospectively 117 cases of atherosclerosis in the Hospital of Hematology and Blood Transfusion in Ho Chi Minh city showed that: atherosclerosis is very common in elderly and the form of calcified plaque accounts for highest rate. Atherosclerosis is usually associated with other pathological status such as CHA, blood lipid disorder, diabetes and obesity

Extracts from roots and leaves of Polyscias fruticosa Harms. (Araliaceae) and their combination have been studied on lipid peroxidation in mouse brain using an auto-oxidation and a free radical generating system: the Fenton’s reagent (ferrous iron + hydrogen peroxide). All the root, leaf and combined extracts have inhibitory action on peroxidation of lipids and trolox, a water-soluble analogue of vitamin E used as a reference antioxidant compound. The results also indicate that the leaf extract is the strongest of all.

National Institute of Hygiene and Epidemiology combined with International Vaccine Institute to conduct a qualitative study on Japanese encephalitis immunization and control policy in Viet Nam in 2002. The study applied quick assess method including collection information from many source and interview. In 2 months, the study determined experienced lesson of Vietnam in giving Japanese encephalitis vaccine into open immunization program. The study showed that policy of Japanese encephalitis immunization in Vietnam was effect due to suitable strategies and correct decisions.

A clinical trial was performed to evaluate the tocolytic possibility of nifedipin and to propose a treatment regimen for preterm labor in the National Hospital of Gynecol-Obstet from July 2003 to December 2003. There were 40 cases of preterm labor with gestational age 31 weeks and 3 uterine contractions per minute on average. Patients received a 10 mg sublingual loading dose every 20 minutes (maximum dose 40mg), and followed by 20 mg oral dose every 6- 8 hours. Result: the effectiveness in tocolysis of nifedipin is very fast. It took 60-80 minutes to arrest uterine contraction (70- 80%) (including contractions of high frequency and intensity), especially in urgent tocolysis. The lower the frequency and intensity is, the higher and sooner the effectiveness is. 92.5% of delivery were delayed for 48 hours. 82.85% were postponed until 36 weeks, and the mean time of prolonged pregnacy was 39 days. Side-effects were mild and transient and in normotensive pregnant women blood pressure was almost unaffected. This treatment regimen of nifedipin showed the effectiveness in preterm labor. In brief, nifedipin is an effective, safe, convenient and economic tocolytic agent. It may well represent the best suitable tocolytic alternative currently available and can be used widely in Viet Nam.
