105 pregnant women received the spinal anesthesia by dolargan for the abdominal delivery in Son Tay Hospital during 1-12/2000. The duration of action of the drug, duration of analgesia, efficacy of anesthesia, situation of fetus, influences of the spinal anesthesia on some functions, postoperative time were monitored. The results have shown that the spinal anesthesia is a good method of anesthesia in the abdominal delivery. The care of mother is more convenient than other methods of anesthesia, the cost is lower and the safety for mother and baby is high.

The authors presented 37 cases of thymomas operated at Viet Duc Hospital during 1998-2002. The results: 31 males and 6 females with medium age 46.8. The microscopic features were: medullary thymoma: 1, mixt type: 6, predominantly cortical thymomas: 4, cortical thymomas: 4, squamous cell carcinomas: 11 (4 keratinazing and 7 nonkeratinazing, basaloid carcinomas: 2, clear cell carcinoma: 1, small cell carcinoma: 6, sarcomatous carcinoma: 1 and anaplastic carcinoma: 1. Eleven cases developed the superior vena caval syndrome and most of these indicated the malignancy in the microscopic features. The relations between clinical and pathological aspects were discussed.

Lectin (APA) was purified from jequirity bean (Abrus precatorius) by affinity chromatography on insoluble ovomucoid. Lectin (APA) and conjugate Lectin-biotin have been used in ELLA technique (Enzyme Linked Lectinosorbent Assay) to detect some pathogenic bacteria. Based on its specific bioavailability to the poD-Gal sugar compounds in cell membrane, lectin (APA) was capable of differentiating B. anthracis and B. cereus from S. flexneri, S. sonnei, C. diphteria, and Salmonella and Staphylococcus aureus.

In this study, the usefulness of the lectin reactive alpha-fetoprotein (AFP-L3) in patients with HCC, CLD and patients with HCC treated by transcatheter oil chemoembolization (TOCE) was examined. AFP-L3 levels were measured by lectins affinity electrophoresis and antibody affinity blotting. After TOCE, 40 HCC patients were classified into two groups: 1st group (n=27 with AFP-L3<15%; 2nd group (n=13) with AFP-L3>15%. Results: The mean value of AFP-L3 in the 110 HCC patients was 54.6+/-23.7%, significantly higher (p<0.001) than the value in CLD (11.2+/-3.1%). When the cut-off level was set 15% for AFP-L3, the sensitivity was 96.4%, and the specificity was 95%. Survival rates after 12 and 18 months for all 27 patients calculated according to the Kaplan-Meier methods were 88.9% and 63% in the 1st group and 38.5% and 15.3% in the 2nd group, respectively. The recurrence of HCC for 1st and 2nd group were 10.2+/-3.5 months and 12.0+/-1.7 months. Conclusions: AFP-L3 is a useful marker for the diagnosis of HCC and for differentiation of increased AFP in HCC and CLD. AFP-L3 could be useful for the evaluation of curability after TOCE.

Studying of 15 patients with tuberculous ureteric stricture treated by extraversical ureteral reimplantation (4 males and 11 females, 10 cases of unilateral ureteric stricture and 5 cases of bilateral ureteric stricture). The mean operation time: 101.6 minutes, mean estimated blood loss: 68.6ml, mean time of removal of urethral catheter: 7 days, mean postoperative hospitalization: 8.13 days. Postoperative complications were minimum: 1 case of mild infection because oh ureteral stent migration, 1 case of moderate intraversical bleeding... Long-term outcomes of operation were satisfactory: on 12 patients performed follow-up UIV, 8 with good amelioration and 3 with pretty good amelioration, 1 without amelioration, mean follow-up duration: 15.5 months

Process of multiply NS4 gene of hepatitis C virus by PCR technique used with cDNA supplied from ARN. Couple of specific preys for NS4 gene and catalytic enzyme was Deep Vent ADN polymerase. Suitable MgSO4 level to multiply NS4 was 4mM. Fasten prey temperature was factor affecting to specificity of product. Result of electrophoresis showed that the most suitable temperature was 55oC and 57OC. In 200 µM dNTPs level, PCN product was sharp and correct to primary predictable size, in 50 or 100 µM dNTPs level, PCR wasn’t viewed, in 150 µM level, PCR was more blear than using 200 µM level. So dNTPs level was 200 µM

Study serum of 443 health adults over 20 years old, negativeness with HIV and HBV and serum of 408 health childrens from 2 to 10 years old in Ha noi, Hai Phong and Thanh Hoa. Measles antigen were refined from Vero cell causing infection of Edmonton strain by Gradi extra centrifugal method with Sucrose density 20-60%. HA value of 1/11,024 showed high antigen specificity. 6 bunchs of protein were correllated with specific polypeptid strings of measles virus. After that, technical process and MAC ELISA-IgG were completed. Results: rate of measles immune response in adults was 100%, in which IgG value was high in 24%, moderate in 73.1% and low in 2.8%. Rate of serum IgG value in children was different to adults: positive serum 88%, negative 8.5%. Negative rate showed that the vaccine boosters were necessary

The evaluation trial was conducted from August 2004 to March 2005 in the laboratory of the National Institute of Malariolgy, Parasitology and Entomology, Ha Noi. Bioassays with An.dirus and Ae.aegypti (reared mosquitoes) were made according to the WHO method for evaluation of susceptibility and residual effects of the insecticide on the painted and nylon wall surface. Ale lose sprayed at the dose of 30mg ai/m2 were found to produce residual effect for 6-7 months on the painted wall surfaces (mosquito mortalities: 51.1%-67.8%) and for 4-5 months on nylon wall surface (mosquito mortality: 55.6%-67.8%).

2 patients received the microsurgical flap. Both flaps has been living well, the functions were recovered well. The shape of face was relatively equal. The patients received a false maxila and teeth. The moving functions of the leg donated the calcaneal bone were well recovered without influencing the life. The conclusion: the defct of facio-maxillary area is a major lession that should be treated. The technique of microsurgery with using the calcaneal bone flap helps reconstructing the facio-maxillary area.

This retrospective study was undertaken to characterize the endoscopic and histopathologic pattern of patients with gastro-esophageal reflux with esophagistis. We investigated 58 patients (24 women, 34 men: mean age 44.33 years). The histopathologic pattern was classified in 3 grades: Grade 1: 19 patients, grade 2: 18 patients, grade 3: 21 patients. The sex ratio, age, endoscopic and particular histopathologic pattern was discussed. We conclude that the gastro-esophageal reflux disease is a common complaint in adult population. Despite it is not a severe damage, it can complicate to Barret’s oesophagus, a premalignant lesion of esophageal adenocarcinoma.
