To evaluate the effects of zinc on chronic anorexic children, we have divided 132 chronic anorexic children aged 3-48 months old into two groups. The test group was supplemented with iron, vitamins and 10mg of elemental zinc daily orally while the control group was supplemented with iron, vitamins. The results have shown that appetite, energy intakes and growth rate in the test group were improved better than those in the control group (P<0.001; P<0.001; P<0.001 and P<0.025). Initial serum zinc concentration of the chronic anorexic children in the test group is concerned obviously with rehabilitations of energy intakes (P<0.002). Weight and height velocities of the anorexic children with low zinc concentration in test group were lower than those of the anorexic the test group (P<0.005; P<0.005). Zinc supplementation has clearly affected to treat chronic anorexia in children.

System suitability tests are an integral part of liquid chromatographic technique. They are used to verify the resolution (R) and reproducibility of the analysis to be done. HPLC method for assaying the related substances test of Cefaclor in raw material as well as in pharmaceutical dosage forms introduced to some pharmacopoeia such as EP, USP need to use Delta- 3 cefaclor as the internal standard to verify the suitability of chromatographic system. In case of lacking it to use, Cephalexin can be used as the internal standard in place of Delta-3 cefaclor. cell

The study was conducted to evaluate the acceptability and the adaptability with a new food (yogurt) of young healthy children in community setting. Seventy-nine healthy children who were 6-24 months of old at baseline from a rural commune were selected to involve in this study. The children received 150 ml yogurt each day, six day a week for 13 weeks. The amount of yogurt consumed by children was recorded daily by health workers. In the first week, the 6 to 12, 13 to 18 and 19 to 24-month-old children consumed 68%, 65% and 84% serving portion, respectively. Age was the only factor that affected on the acceptability of the children (p<0.01). The young children adapted well with yogurt within 1-3 weeks. The older children adapted faster than the younger ones. The results showed that the acceptability and adaptability of the young children with new foods was high, although was slower in the younger children.

Background: There is limited study on risk behavior and HIV in fishermen. Objective: To define risky behavior and HIV among fishermen in Kien Giang. Subject and Method: Cross - sectional survey on 499 fishermen in Kien Giang. Results: The average age was 28.9, and approximately 43.5% were not married. Almost all were educated to primary and secondary level, while the illiterate ones accounted for 9.0%. The average age when people had sex for the first time was 19.7. The rate of drug abuse was 0.8%, but none of them injected drug. The number of people who thoroughly understood about HIV preventions accounted for 79.8%. A majority of people who answered showed positive attitude towards PLWA, 95.1 % of whom implied that they were ready to take care of HIV - infected family members. However there was about 77.8%, people who wanted to keep their infection status confidential. The proportion of people always using condom when having sex with CSWs during the past 12 months was only 65.9%. The rate of people who already had an HIV test was 11.2% and the rate of HIV infection among the target group accounted for 0.6%. Conclusion: Direct communication model with the message on using condoms when having sex and consultation for examination is suggested for prevention on HIV/AIDS in fishermen.

Background: Lai Chau is one of northwestern provinces of Vietnam, where there was a drug vice and high prevalence of drug users. It is necessary to evaluate the situation of HIV infection in this group. Objectives: A study on HIV prevalence and factors relating to the behaviors of HIV Infection among Injecting Drug Users (IDUs) in various districts of Lai Chau province. Subjects and method: A quantitative, cross-sectional study was carried out on 330 IDUs in Lai Chau town and 3 districts of Lai Chau province from January to December 2007. Results: 40.30% of the IDUs tested positive for HIV, nearly 2 times higher than the prevalence in 2006 (23.2%). 87.27% of the IDUs never re-used their syringes and needles. However, 12.4% still sometimes re-used their syringes and needles. Of 43 IDUs (12.73%) who re-used their syringes and needles, only 27.91% always cleaned their syringes and needles, 23.26% cleaned their syringes and needles most of the time after using them and up to 27.91% only sometimes cleaned their syringes and needles. Most IDUs use heroin (97.88%). Percentage of IDUs sharing syringes and needles accounts for 12.42%. 10% of the IDUs had sexual intercourses with commercial sex workers within the last month. There is a relationship between the time of using drugs and the HIV prevalence rate. There is a double risk of HIV infection for the IDUs injecting drugs for 5 years and upwards compared to those injecting drugs less than 5 years. (p <0.05, OR = 2). Conclusion: It is required to develop communications in order to change the behaviors of HIV infection among IDUs in Lai Chau province.
