A cross study on 305 children selected randomly and direct interviewing their parents. The results showed that: overall percentage of obesity was 3.49%, in kindergarten children was 4.29%, in primary school children was 2.7%. Percentage of malnutrition in underweight was 9.47% and the rate of stunting and wasting was 8.93% and 4.29% respectively. High education level in parents of obese children was 14.8% and in parents of normal children was 40.9%. Average body-weight of parents of obese children was higher than that of parents of control children. Obese children consumed much more food every day than normal children.

In the paper, 323 species belonging to 103 plant families (about 2.82% of the total species of the vascular flora and about 17.23% of the medicinal plant species of Vietnam) are reported. Of them, 88 species are reported in the first time. The diversity on species, on life-form and on used parts is also analyzed. From the analysis, some of the most important species are selected for the priority of exploitation and use

In this study, 35 rabbits were divided into 2 groups: group A included 15 rabbits, that were intoxicated with nitrogen oxide at dose 274.48 mg/m3 of the air; and group B included 20 rabbits that were intoxicated at dose 203.04 mg/m3. Results: all of rabbits in group A died from acute pulmonary edema; PaO2 strong decreased after intoxication, CtO2 decreased at 8 hours after intoxication, PaCO2 and t.CO2 in arterial blood increased. In group B, 55% of rabbits died after intoxication, and the changes of blood gas measurements were similar to those in group A. However, these measurements in survival rabbits were decreased after 24h and then increased at 48h after intoxication

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'

This study was conducted to determine the prevalence and characteristics of pathogenic Escherichia (E.) coli strains from diarrheic calves in Vietnam. A total of 345 E. coli isolates obtained from 322 diarrheic calves were subjected to PCR and multiplex PCR for detection of the f5, f41, f17, eae, sta, lt, stx1, and stx2 genes. Of the 345 isolates, 108 (31.3%) carried at least one fimbrial gene. Of these 108 isolates, 50 carried genes for Shiga toxin and one possessed genes for both enterotoxin and Shiga toxin. The eae gene was found in 34 isolates (9.8%), 23 of which also carried stx genes. The Shiga toxin genes were detected in 177 isolates (51.3%) and the number of strains that carried stx1, stx2 and stx1/stx2 were 46, 73 and 58, respectively. Among 177 Shiga toxin-producing E. coli isolates, 89 carried the ehxA gene and 87 possessed the saa gene. Further characterization of the stx subtypes showed that among 104 stx1-positive isolates, 58 were the stx1c variant and 46 were the stx1 variant. Of the 131 stx2-positive strains, 48 were stx2, 48 were stx2c, 11 were stx2d, 17 were stx2g, and seven were stx2c/stx2g subtypes. The serogroups most prevalent among the 345 isolates were O15, O20, O103 and O157.

Introduction: The need for gama \u2013 globulin, especially gama - globulin - anti \u2013 HBs, is huge in Vietnam. A number of patients cannot to afford use them due to the high price as they are imported. Meanwhile, Vietnam has high quality input sources for producing gama \u2013 globulin. \r\n', u'Objectives: To study the production process of gama - Globulin from Human Plasma and Standard gama - Globulin with Rich of Anti \u2013 HBs. \r\n', u'Subjects and method: 168 samples of human plasma from voluntary blood donors, which had been screened with for transfusion transmittable infections (TTLs), were chosen as plasma with rich of anti - HBs. The plasma with anti - HBsAg was precipitated with ethanol 25%, pH 6,9 to gain gama - globulin with rich anti - HBs, which was dried by Dutch Ly - 3 - TTE machine. Activation of anti - HBs gama - globulin was identified by a standard method of the degree of antibody specific for anti - HBsAg kit of BIORAD, \r\n', u'Results: The purity of the gama - globulin achieved was 93%, which was almost equal with the results of some foreign researchers (7.8), the activation of anti - HBs was 1:128 dilution degree. The productivity of gama - globulin gaining from 1 litter plasma was 6.0 gram. This new issue was first demonstrated in Vietnam. \r\n', u'Conclusion: We can domestically produce anti-Bs gama - globulin with high degree of activeness (1:128) from human plasma by the precipitating method with ethanol, pH and low temperature. \r\n', u'
