Background: Salmonella typhi (S.typhi) is the major cause of human typhoid fever outbreaks. In fact, there were various typhoid fever outbreaks that occurred in China, and India that was caused by S.typhi strain without Vi antigen. Objective: To determine whether the S.typhi strains with mutation of gene encoding Vi antigen exists in Vietnam and the rate of mutation (if they exists). Subject and methods: 450 S.typhi isolates were collected in the Northern, Central and Southern Region of Vietnam during 1995 and 2005. The isolates were analyzed by the PCR method in order to detect mutants by using 2 primer pairs of tviB and DE. Results and Conclusion: There was no clear evidence on the relationship between the widely used Typhi Vi vaccine in Vietnam and the existence and spread of the mutation of gene encoding Vi antigen of S.typhi. 30 out of 450 isolates mutated losing the gene encoding of Vi antigen, making it 6.67%. These isolates were spread out between 1995 and 2005 throughout the Northern, Central and Southern Regions of Vietnam, with a peak in 1999. A noteworthy point was the rate of mutation of S.typhi losing the gene encoding of Vi antigen in Vietnam during the period of study. However, the mutation rate of S.typhi in Vietnam was still higher than the ratio of similar mutations being published in the other countries worldwide and higher than the recommended level of the World Health Organization.

Background: Flu and avian flu in humans are events in a number of countries all over the world. In Vietnam, there were some investigations on knowledge, attitude and practice for preventing flu and avian flu on several groups of the population and pharmacists in Tra Vinh province. However, there is no research for this issue in Hanoi city while the evident need for the planning of public health programs is required. Objective: To describe knowledge and identify the requirement of flu and avian flu information among pharmacists in Hanoi city. From that, some recommendations for intervention programs are proposed. Subject and methods: A cross-sectional study was conducted on 143 pharmacists in Hanoi city with a structured questionnaire of knowledge and requirement of flu and avian flu information from October, 2007 to January, 2008. Results and Conclusion: Generally, knowledge on flu and avian flu is not yet comprehensive and sufficient. Requirement for flu and avian flu information was quite in demand, especially via television, capacity building training, having more communication materials and experience exchange workshops. Several interventions need to be directed towards: comprehensive communication on flu and avian flu to pharmacists, which aims to help them understand sufficiently and comprehensive about flu and avian flu; capacity improvement for pharmacists should pay attention to several channels such as television broadcasting communication, short-term training, disseminating relevant materials and perhaps experience exchange through seminars.

Background: hepatitis due to virus B is now one of the leading concerns in the community health care throughout the world. Vietnam was a country located in high risk areas for hepatitis B virus (HBV) infection with rate of HBV infection in the community ranged from 11.3 to 25.5%, the rate of HBsAg positive in pregnant women from 12-16%. Objectives: to evaluate knowledge and practice on HBV prevention among pregnant women in Hanoi in 2005-2006 period; to study on some related factors of HBsAg positive rate. Subjectives and Method: a cross sectional study (with analysis on knowledge and practice about HBV prevention) was carried out on 1.300 pregnant women above 28 gestational weeks at Hanoi Obstetrics/Gynecology Hospital in 2005. Results: the rates of women with knowledge about HBV prevention were 38.5% at good level, 24.4% at acceptable level, and 37.7% at unacceptable level. The rates of practice on HBV prevention were 58.5% at satisfied level and 41.5% at notsatified level. Knowledge was likely related to practice, age, educational level, and HBV positive rate. Practice on HBV prevention was also related to HBV infection. Conclusions: the rates of women with knowledge about HBV prevention at good level were relatively high. The rates of practice on HBV prevention at satisfied level were relatively low. Related factors of HBsAg positive rate: knowledge and practice about HBV prevention.

Objective: To investigate antidiabetic and antioxidant activities of the extract and fractions from Vietnamese red seaweed Laurencia dendroidea. Methods: The seaweed Laurencia dendroidea was extracted by using microwave-assisted extraction method in 80％ methanol. The seaweed extract was then fractionated using different solvents (n-hexane, chloroform, ethyl acetate, butanol and water). These obtained fractions were evaluated for α-glucosidase inhibitory and antioxidant activities. Antioxidant activities were tested using DPPH, nitric oxide radical scavenging and metal chelating assays. The enzyme inhibition mode was determined using Lineweaver-Burk plot. For acidic and thermal stabilities, the ethyl acetate fraction was treated at pH 2.0 and 100 ℃, respectively. The residual inhibitory activity of the fraction was calculated based on the initial inhibitory activity. For in vivo antidiabetic activity, mice were divided into four groups, including normal control, diabetic control, diabetic mice treated with ethyl acetate fraction and diabetic mice treated with gliclazide. Blood glucose level of treated mice during acute and prolonged treatments was measured. To evaluate the toxicity of the ethyl acetate fraction, the body weight changes and activities of liver function enzymes (aspartate transaminase, alanine transaminase and gammaglutamyl transferase) were carried out. Results: The extract of Laurencia dendroidea showed strong α-glucosidase inhibitory and DPPH radical scavenging activities. Methanolic concentrations affected both α-glucosidase inhibitory and antioxidant activities. A 80％ aqueous methanol was the suitable solvent for extraction of enzyme inhibitors and antioxidants. Among solvent fractions, ethyl acetate fraction had the highest inhibitory activities against α-glucosidase with a mixed type of inhibition and the strongest antioxidant activities, and was stable under acidic and thermal conditions. The ethyl acetate fraction treated diabetic mice significantly reduced blood glucose level compared with the diabetic control group (13.16 mmol/L vs. 22.75 mmol/L after 3 hours of treatment). Oral administration of ethyl acetate fraction did not exhibit toxicity at a dose of 100 mg/kg body weight as determined by body weight changes and liver biochemical parameters. Conclusions: Laurencia dendroidea could be a potential source for production of antidiabetic and antioxidative agents.

Background: Standard treatment for pleural infection includes of drainage and antibiotics. Chest tube drainage often fails if the fluid is loculated by fibrinous adhesions. Intrapleural fibrinolysis may facilitate pleural drainage. Objective: To evaluate the role of Streptokinase (STK) in the treatment of empyema and exudative pleural effusions. Subjects and method: A study included 34 patients (21 patients with exudative pleural effusions, 13 patients with empyema), aged 15-77 years. All patients received intrapleural STK daily with dose of 300.0000-500.000 UI for empyema and 300.000 UI for exudative pleural effusions. Response was assessed by clinical outcome, pleural fluid drainage, chest radiography, pleural ultrasound. Results: Mean pleural fluid drainage after STK instillation was higher in all patients. Pleural fluid drainage was 640 \xb1 494 ml before STK instillation and 823 \xb1 755 ml after STK instillation for empyema; 765 \xb1 691 ml before STK instillation and 1,033 \xb1 757 ml after STK instillation for exudative pleural effusions. The success rate of clinical outcome was 100%. Only 2 patients required decortications. Fever occurred in 3 patients (8.8%) and allergy in 1 patient (3%). Conclusions: Intrapleural STK was safe and effective in the treatment of empyema and exudative pleural effusions. STK prevents pleural adhesions and reduces the risks for surgery.
