In this study, 119 G6DP deficient individuals of 2871 people belong to Kin, Muong, Racley, Tay ethnic groups living around Hanoi, Hoabinh, Khanhhoa were detected as G6PD deficiency. 37 DNA samples of the G6DP deficient individuals (32 cases) and 5 normal people (5 cases) had been analyzed. 7 mutation variants of 30 G6DP deficient individuals had been identified, including Viangchan, Chatham, Chinesse-5, Union, Canton….The G6DP Union and Chinesse-5 were only found in the Muong people, in which G6DP Union was the most predominant mutation of this ethnics (8/18 cases). In addition, there were three Muong-families, two of which had G6DP mutations in both the father and the mother; the rest family, Canton mutation in both the mother and the son.

385 Kinh and Muong vasectomized men and 40 men (control) were subjective of the study. All are healthy, ages of 30-60, all had at least a child. The blood samples were taken at 6 weeks, 3-6 months, 7-12 months and 6 years after operation. The Franklin - Duker agglutination test and passive immunofluorescence test for detecting sperm antibodies were used. The results were as follows: in 40 control, there was only one, who had agglutinating sperm antibodies, i.e 2.5%; 39.5% incidence of sperm antibodies were found in vasectomized men one year after operation. In the time of 6 weeks, that was 9%, less three months was 12.1%, 3 to 6 months was 40.3%, 7 to 12 months was 48.8%; 25.3% vasectomized men exhibited sperm antibodies 1 to 6 years after operation; the sperm antibodies incidence of Kinh men was lower than Muong men, that were 38.4% and 44.4% respectively; the antibodies detected by immunofluorescence test were IgG binding in the acrosome or neck and tail of spermatozoa

Background: Epidermal Growth Factor Receptor (EGFR) is a transmembrane cell-surface glycoprotein with intrinsic tyrosine kinase activity. EGFR has been shown to stimulate cell proliferation and to enhance the migration and invasiveness of breast cancer. EGFR is expressed in epidermal cell lines and have been implicated in the pathogenesis of many different types of cancer. Objective: To evaluate the level of EGFR transcript in breast cancer and normal tissues; comparison the EGFR transcript level at different development stages and cancer cell types. Subject and methods: Total RNA from 62 tissue samples including 47 breast cancer and 15 normal tissues were extracted; cDNA synthesis by reverse transcript polymerase chain reaction, EGFR transcript level were determined using semi-quantitative RT-PCR. Result and conclusions: EGFR transcript level was highly expressed in breast cancer tissues compared to the normal tissues. Especially, its expression was related to the different status and cancer cell types of breast cancer. There was a difference of EGFR transcript level between histological pathology\u2019s forms of breast cancer in the same stage.

Background: Human Heparansulphate interacting protein (hHip) has been shown to participate in biological processes of cells. Several studies indicated that hHip transcript is up regulated in several of cancer tissues including those of thyroid, colon, breast and prostate. Antibody against hHIP is necessary for methods to evaluate protein level of HIP in cancer tissues. Objectives:The aims of study was to induce anti hHIP antibody in rabbit and purify and conserve purified anti hHIP antibody. Subjects and method: The study included 9 adult and healthy rabbits with the weight 2 - 2.5kg. Immunization hHIP peptide-KLH in rabbit. Purify anti hHIP antibody using affinity chromatography. Results: The results shown synthesize hHIP peptide and conjugate it with carrier protein. Sensitive rabbit better meet with hHIP-KLH antibody. The Ig concentration obtained in sensitive rabbit was rather high and equal. Immunization hHIP-KLH successfully in rabbit. Obtainment valuable amount of anti hHIP antibody. Conclusion: Successfully induce and purify anti hHIP antibody from rabbit. Establish a standard protocol for polyclonal antibody against small peptide in rabbit.\r\n', u'\r\n', u'

Background: According to WHO, there are 5 million deaths from kinds of injury a year in the world, of which 875000 deaths occur in children under 18 years old. Injury leads to 40000 deaths which account for 10.7% deaths due to all other causes a year in VietNam. Objective: To show conclusions of the situation of child injury, recommendations for prevention of child injury and methods in order to enhance emergency activity in Vietnam. Subjects and method: The authors collected information about all patients who had emergencies due to injury at Viet Duc hospital, from March 26th 2006 to Octorber 26th 2006. However, supervised cases were the patients under 18 years old who were examined and treated at the Department of Emergency. Results: During the period of study, 2536 patients under 18 years old were examined for injury, of which death and coming back home for death were 83 cases (3.27%). 974 children had emergency resulted from injury: male was more than female: 697 verus 227. The leading causes of child injury were fall and traffic accident, respetively 34% and 60%. The most common traumas were traumatic brain injury (45%), limbs injury (41%). Although most of cases had first aid at the hospitals in district or province level, the rate of non-first aid cases was high (34%). Conclusion: Child injury is a leading cause of child death in hospitals. Methods for prevention of child injury should focus on educating and propagandizing to minimize injuries caused by traffic accident and fall.

Objective To evaluate the impact of plant growth regulators including kinetin (KN), benzyl adenine and naphthalene acetic acid, yeast extract and casein hydrolyzate on biomass accumulation of Vietnamese ginseng Panax vietnamensis (P. vietnamensis) in cell suspension culture. Methods Cell suspension cultures were established from friable calluses derived from leaves and petioles of 3-year-old in-vitro P. vietnamensis plants. The cell suspension cultures were grown in Murashige and Skoog basal media supplemented with various concentrations of KN, benzyl adenine, naphthalene acetic acid, and yeast extract and casein hydrolyzate. Results All tested factors generated an increase in the cell biomass of P. vietnamensis in suspension culture, but the impact of each varies depended on the factor type, concentration, and incubation period. Addition of 2.0 mg/L KN resulted in the largest biomass increase after 24 d, (57.0 ± 0.9) and (3.1 ± 0.1) mg/mL fresh and dry weight, respectively, whereas addition of benzyl adenine or naphthalene acetic acid produced optimum levels of Panax cell biomass at 1.0 and 1.5 mg/L, respectively. Addition of the elicitor yeast extract led to a 1.4–2.4 fold increase in biomass of P. vietnamensis, while addition of casein hydrolyzate enhanced biomass accumulation 1.8–2.6 fold. Conclusions The addition of each factor causes significant changes in biomass accumulation of P. vietnamensis. The largest biomass accumulation is from cultures grown in MS media containing 2.0 mg/L KN for 24 d. The outcome of the present study provides new insights into the optimal suspension culture conditions for studies on the in vitro cell biomass production of P. vietnamensis.
