There is a conservative region of more than 130 bp long in the mitochondria genome of Leishmania mexicana M379 clone E8, and this it is found across many other Leishmania spp. Based on this notion, a pair of PCR primers were designed to amplify the corresponding regions in the minicircles of many other Leishmania species such as L.major, L.donovani. PCR method can be used to detect protozoa in Vietnam

The study was conducted in 47 patients (34 males, 13 females) with coronary artery disease or suspected coronary artery disease who were underwent SBSE from May 2002 to October 2004 at 115 People Hospital. Results: CAD was presented in 22 patients: among which, 7 cases with lesion of one major branch, 7 cases with two branches and 8 case with three branches of coronary artery. SBSE test was positive in 20/22 patients, overall sensitivity of 91%, specificity of 80% and accuracy of 85%. The sensitivity was greatest for the font interventricle artery (81%), compared to sensitivity for right coronary artery and the left coronary artery was 56% and 31%, respectively (p<0.005). For identifying patients with multivessels CAD, sensitivity 55%, specificity 97% and accuracy 83%. SBSE is a useful tool for evaluating CAD, and identifying both the location and extent of disease.

The study was conducted at Hanoi Obstetrical and Gynecological Hospital, combining quantitative and qualitative research methods. Results: the study showed that there was a tendency for pregnant women to over-use ultrasound scanning. The reasons for this included women’s perceptions of the usefulness of ultrasound scanning, their serious worries for the fetus, as well as the effects of the market economy on this health service. Over-use of obstetrical ultrasound scanning was not only related to the perception, demands and psychology of pregnant women, but also to socio-economic changes associated with the economic reforms and the liberalization of the health care system.

Vnukovo-32 a cell culture rabies is used to study the vaccine strain technology of inactivated culture rabies vaccine production in primary hamster kidney cells. The master and working seeds meet the criteria of rabies vaccine strain titer (5.5 log LD 50 - 7.1 log LD 50/ml) according to WHO standard. During the study, we have used the procedure for inactivated, non concentrated rabies vaccine production of Russia and other countries procedures as references. The result was we constructed the procedure for inactivated, concentrated cell culture rabies vaccine production at laboratory scale.

The oral use of "Thap Toan Dai Bo" pills on experimental rats showed a tonic effect with a tonic coefficient of 1.9230.333. 80% of animals had had positive increase of weight. The dose of 0.1ml/10g and 0.2ml/10g, the effect of improving the memory was notified in the time of study. The staying time in light room T (second) and the rate of positive memory in the group of rat using "Thap Toan Dai Bo" was higher than control group with a statistical significant difference. The preparation has not poisonous, without side effect.

Studying on 1405 sera were collected from 1159 patients ( male 58.55%; female 41.44%) with encephalitis syndromes which were treated in Bach Mai hospital. Using MAC-ELISA to estimate antibody for Japanese Encephalitis in these patients. The results were as following: The general positive rate was 16.64% The positive rates by MAC-ELISA were 16.54% (46/278), 10.31% (22/223),...and 13.36% (25/187) in 1997, 1998,...and 2001, respectively. The positive rates for males were 58.55%; female 41.44%. The positive rates divided by the age: 1-15 years, 36.84%; 16-60 years 63.16%.
