Background: Facing urgent requirements of the rapid diagnosis of tuberculosis nowadays, our laboratory have improved the multiple PCR for 3 target genes spontaneously (IS 1081, IS 6110, 23S rDNA) and developed into the multiplex PCR kit to improve the effects of diagnosis of tuberculosis. Objective: To evaluate the multiplex PCR kit for the 3 target genes (IS 1081, IS 6110, 23S rDNA) for the diagnosis of tuberculosis on standard panel and clinical specimens. Subjects and method: DNA extracted from M. tuberculosis strains and clinical specimens were amplified by multiplex PCR kit, comparison with singleplex PCR for each target gene. Results: On standard panel, sensitivity and specificity reached 100% and detected limitation was 100 fg DNA template (about 3 M. tuberculosis cells). Multiplex PCR kit detected 195/307 (63.52%) suspected clinical specimens compared with singleplex PCR which detected 106/307 (34.53%) for IS 1081, 182/307 (59.82%) for IS 6110 and 136/307 (44.30%) for 23S rDNA. Conclusions: PCR amplification with one target gene was insufficient for diagnosis of the tuberculosis strains in Viet Nam. Multiplex PCR kit for 3 target genes simultaneously (IS 1081, IS 6110, 23S rDNA) could detect all tuberculosis strains.

Background: Helminth infection cause bad impacts on human health, especially for children.Helminth infection directly related to poverty, bad hygiene, low quality water supply, people awareness... Objective: To investigate the current situation of soil transmitted helminth infection in Son La province. Subject and Method: A total sample of 7,150 fecal specimen collected from72 hamlets, 18 communes in 6 districts of Mai Son, Muong la, Thuan Chau, Song Ma, Quynh Nhai and Yen Chau were examined for soil-transmitted helminths. Result: A cumulative infection rate of 93.45% was found, of which Ascaris: 85.85%, Trichuris: 24.52%, and hookworm: 18.92%. No different' infection rate was found between males and females but it was higher with ages. The prevalence of Trichuris and hookworm was higher in adults against children and higher with the older ages. The infection of Trichuris and hookworm in adults was higher than that in children. The single helminth infection rate was 82.17%, and mixed infection of two species was 15.9% and three species 0.43%. The helminth infection among Sinh MUD ethnic group: 97.2%, Thai ethnic group: 96.6%, La Ha ethnic group: 85%, Kinh ethnic group: 80.62%, and H'mong ethnic group: 45.96%. The hookworm infection rate of Kinh and H'mong groups was found higher that of the others ethnic groups. KAP surveys were conducted with 2,188 households showing a high latrine coverage of 90.6%, of which 92.9% of latrines were self-made. The more was the rate of self-made latrine, the higher was the helminth infection. Conclusion: Low awareness and knowledge of the local people on helminth infection was found so as they do not know how to prevent from helminth.

Background: In Viet Nam, there were many researches on determining lead level in blood, food and environment. But until now, there were not researches on determining lead level in fishermen community. Objectives: Determine trace amount of lead by von-ampe dissolve anot using electrode BiFE. Analysis on trace amount of lead in blood and urine of fishermen in Canh Duong village. Propose solutions for preventing lead poisoning in studied community. Subjects and method: Fishermen in Canh Duong village, Phu Loc, Thua Thien Hue province. The method differential pulse-anodic stripping voltametry (DP-ASV) using Bismuth Film Electrodic in situ was successfully applied to measure lead levels in blood and 24h urine of fishermen in Canh Duong village. Results: The mean level of lead in blood of the suspected group (fishermen) in Canh Duong village (34,7 \xb5g/dL) was higher than that of the control group (16,3 \xb5g/dL). For both groups, 37 out of 40 blood samples (92,5%) had lead level higher than WHO\u2019s recommended level (10 \xb5g/dL). Especially, 6 of 40 blood samples (15%) had lead level higher than 50 \xb5g/dL. The lead level in 24h urine of suspected group had slightly higher (about 1,2 times) than that in the control group. The lead level of the two groups was much higher than the normal level. Conclusion: The method DP-ASV/BiFE in situ was applied successfully to determine lead level in blood and 24h urine. The investigative results of related information showed that: the risk of chronic lead poisoning in studied community very high.
