1.Study on skin lesions caused by rocket liquid and efficacy of some drugs for treatment.
Journal of Preventive Medicine 1999;9(2):51-56
The study was carried out in 36 grown-up rabbits with average weight 2±0,3kg. The results showed that: skin tissue exposed to oxidant was severe injury with necrosis area into muscle, bone and healing process was slow. Skin injury caused by burn substance was milder: main characteristics of skin lesions were congestion and edema, healing process is faster. Treatment of the skin lesions: spraying water on the contaminated area of the skin and application of B76 everyday was effective. Healing image of the skin tissue appeared early and fast.

Background: Success in preventing HIV transmission from mother to child has been confirmed, however intervention remains difficult in both services and access barriers due to discrimination and stigma. Objectives: To clarify the HIV prevalence in pregnant women and evaluate the indicators related to the impact of intervention on prevention of mother-to child transmission of HIV. Subjects and method: This study was carried out in 5 districts in 5 provinces that implemented the Prevention of Mother to Child Transmission (PMTCT) Project. The interventions included the training to provide knowledge, skills on counseling, testing and supervision on PMTCT. The data were collected from designed-questionaires. Results:The results showed there are 100% of pregnant women that came for antenatal visits, had voluntary test counseling. The prevalence of HIV (+) among pregnant women was 0,43%. There were 57 infants born to mothers with HIV (+); received prophylaxis treatment. At the time of the study, there were 31 infants at 18 months of age that received HIV test and all of them were confirmed as negative. Conclusion: Intervention on PMTCT was effectively achieved and should be expanded nationally. Communication, counseling is very important to encourage pregnant women with HIV (+); visit for antenatal care, followed up by health facility and strict adherence to the PMCT schedule to diminish the chance of transmission to their infants.

Background: HbA1c quantification is the first important work in long- term controlling of diabetes, which helps to assess the status of diabetes from 2 to 3 months before testing. HbA1c is essential testing to follow up compliance with treatment or not of patients.\r\n', u'Objectives: To study the role of blood HbA1c and micoalbuminuria in the treatment of diabetes.\r\n', u'Subjects and methods: The study was conducted on 124 patients (71 male and 53 female) suffering from diabetes mellitus. Among them, 124 patients were tested for blood HbA1c, 52 patients were tested for both blood HbA1c and micoalbuminuria. The study used the automatic immunological and biochemical techniques. \r\n', u'Results: Concentration of HbA1c was 8.10\xb12.65%, glycemia 9.83\xb14.82mmol/l, urinary micro albumin 76.5\xb196.90mg/l.\r\n', u'There was close relationship between glycaemia and HbA1c; but the relation between micoalbuminuria with HbA1c and glycaemia was not found. The control of diabetes mellitus was poor if glycaemia over 10.0mmol/l and/or HbA1c over 10%. \r\n', u'Conclusion: The techniques applied in the study were precise, rapid and convenient for the patients.\r\n', u'

Vietnam is undergoing a rapid social and economic developments resulting in speedy urbanization, changes in methods for animal production, food marketing systems, and food consumption habits. These changes will have major impacts on human exposures to food poisoning. The present case study aimed to estimate hospitalization costs of foodborne diarrhea cases in selected health facilities in Vietnam. This is a facility-based cost-of-illness study conducted in seven health facilities in Northern Vietnam. All suspect cases of foodborne diarrhea, as diagnosed by doctors, who admitted to the studied health facilities during June-August, 2013 were selected. Costs associated with hospitalization for foodborne diseases were estimated from societal perspective using retrospective approach. We included direct and indirect costs of hospitalization of foodborne diarrhea cases. During the study period, 87 foodborne diarrhea cases were included. On average, the costs per treatment episode and per hospitalization day for foodborne diarrhea case were US$ 106.9 and US$ 33.6 respectively. Indirect cost (costs of times to patient, their relatives due to the patient's illness) made up the largest share (51.3%). Direct medical costs accounted for 33.8%; direct non-medical costs (patient and their relatives) represented 14.9%. Cost levels and compositions varied by level of health facilities. More attentions should be paid on prevention, control of foodborne diarrhea cases in Vietnam. Ensuring safety of food depends on efforts of everyone involved in food chain continuum, from production, processing, and transport to consumption.

A new crinane-type alkaloid, 6-epihydroxypowelline (1), together with six known alkaloids, lycorine (2), 2-O-acetyllycorine (3), deacetylbowdensine (4), 1-epideacetylbowdensine (5), 8-demethyl-3-oxomaritidine (6), and (-)-marithamine (7) were isolated from the whole parts of the Crinum latifolium L. in Vietnam. The structure identification of all compounds was determined by 1D, 2D-NMR as well as HR-ESI-MS spectroscopic techniques. The absolute configuration of these compounds was established by the ECD data. In addition, in vitro inhibition of acetylcholinesterase (AChE) activities was assessed for all isolated alkaloids. All alkaloids had AChE inhibitory effects, with IC50 values ranging from 32.65 ± 2.72 to 212.76 ± 8.30 µM and compound 3 displayed the strongest inhibition of AChE, with IC50 values of 32.65 ± 2.72 µM (in comparison to the reference drug, galanthamine, which had an IC50 of 2.40 ± 0.45 µM).

Background: Human albumin was produced and used in many countries. Cohn's technique had been used to precipitate albumin from human plasma. This technique was easy and cheap and the quality of the product was good. In Vietnam, human albumin had to import, but the prices was very expensive. Vietnam was having good plasma in large quantity and high quality. That\u2019s why research on production plasma albumin was essential.\r\n", u"Objectives: This study aimed at using Cohn's technique improved by Drohan and Van - Aken to produce standard albumin from human plasma. Subjects and method: Human plasma detected VIII-factor was used for present study. Plasma \ufffd?albumin was precipitated by ethanol at low temperature and pH. The collected albumins have been liophilizated and storage at 40C. The quality and quantity of Albumin was evaluated by quantitative analysis and protein \ufffd?electrophoresis. Results: The 418g of albumin powder was produced from 16 liters of plasma detected F \ufffd?VIII. The quality of this albumin come up to standard (>95%) and quantity of albumin collected from one liter of this plasma was 26g. Conclusion: In the Vietnamese condition, the technique of Cohn can be used to produce standard albumin for treatment.\r\n", u'
