A lung function test on 452 school children (239 male; 213 female) from 7-15 years old, at 3 primary schools and secondary schools showed that: The relative figures of each age group were established. The value of lung function test increased with age. In the group with empyema (32 cases) the values of lung function test decreased. But the values of lung function test become nearly normal after 6 months of discharge

During a period 4 year (1.1996- 12.1999) 235 cases were diagnosed with empyema. 169 specimens were cultured. The result showed that: positive 79 (47.3%). Among them the positive gram were: 58 (73.41%), espscially S.aureus: 55 (69.62%). The negative gram were: 21 (26.58%) and most of them were Klebsiella: (12.65%). Antibiotic therapy was applied with drainage effussion. 15 cases were thoracocentesis; 166 cases closed drainage were good result. 54 cases were early decotication. Motality rate was: 9.25%.

A study on 503 pediatric patients with ages of 0-15, and empyema in the Institute of Pediatry during 1990-1999 has shown that the empyema occurred mainly in children with age of under 2 years - the major causative bacterial were S.aureus; negative gram bacterial accounted for 25%. The S.aureus resisted to the common antibiotics and sensitize to aminozides, glycopeptides and beta latamine; the negative gram bacterials resisted to the common antibiotic and sensitize to cefoperazone, ceftazidime, aminozides and quinolones

503 children aged from 0-15 years old with empyema have been treated at the Hµ Néi Institute of Pediatrics during 10 years (1/1/1990 to 1/10/1999). Out of 503 specimens cultured, 240 (47.71%) were positive. The Gr(+) bacteria were the most common cause of empyema (73.33%), especially Staphylococcus aureus (69.16%). S. aureus is sensitive to -lactam (oxacillin, chloxacillin), aminoside (kanamycin, amikacin, netromycin) and glycopeptid (vancomycin) antibiotics. 60 cases infected Gr(-) bacteria (25%) with Klebshiella were predominant. These bacteria were sensitive to antibiotics including cefoperazole (Cefobis); ceftazidime (Fortum), amioside (Kanamycin, Amykacin) and quinolones. The mortality rate was 12.72%.

Background: Production of semi-functional dystrophin protein from the dystrophin gene encoded with a premature stop codon has been shown to modify the severe phenotype of Duchenne Muscular Dystrophy (DMD). The mutation of the dystrophin gene affects the process of complete mRNA and is important in gene therapy. Objective: To analyze the mutation of dystrophin gene in DMD cases. Subjects and methods: A patient with diagnosed with DMD when he was 2 years old, and at age 9, he was completely disabled and had to use a wheelchair. DNA and total RNA were extracted from fresh peripheral blood; cDNA was synthesized by transcript polymerase chain reaction (RT - PCR). PCR, nested PCR or sequence methods were used to determine the mutation of the dystrophin gene. Results: A nonsensical mutation (E638) due to a single nucleotide change in exon 17 of the dystrophin gene (GAA2047TAA) was identified. This mutation affects mRNA splicing process and induces complete exon 17 skipping. Conclusion: Patients, who had E638X mutation with exon 17 deletion in the dystrophin gene, had clinical symptoms of Becker Muscular Dystrophy (BMD). This discovery as a potential target for therapeutic strategies for DMD, to change the severe phenotype of DMD to a milder phenotype (BMD), in order to improve clinical conditions for the patients.

Background: Semiquantitative PCR and quantitative PCR are accurate and simple methods. They are commonly used to determine amplified gene levels in PCR reaction. Objective: Using semiquantitative PCR and quantitative PCR methods to determine HIP transcript levels in cancer and normal tissue; to evaluate sensibility of two methods. Subject and methods: 30 cancer patients were diagnosed based on clinical, para-clinical (ultrasound, biochemistry, histopathology) at K hospital in Hanoi. 15 benign tissue samples are used for control.mRNA was extracted from cancer and normal tissues, cDNA was synthesized by reverse transcript-polymerase chain reaction (RT - PCR); HIP transcript was determined using semiquantitative PCR and quantitative PCR methods. Results: Both methods showed the same results: HIP transcript was increase in cancer tissues but very low in normal tissues. This showed that HIP was linked closely with the development of cancer tissue. Conclusions: Levels of HIP transcript was different between cancer tissue and the normal control. Semi- quantitative PCR and quantitative PCR are useful methods to determine HIP transcript for cancer diagnosis. \r\n', u'\r\n', u'\r\n', u'

Background: Heparan-sufate interacting protetin (HIP) has been known to be up-regulated and expressed in various human cancer cell lines at both transcript and protein levels. HIP\u2019s expression was related to the differentiation status and cancer development. Objective: Using a semi-quantitative PCR method to determine HIP transcript levels in benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia (PIN) and prostate cancer tissues. Subjects and methods: 30 samples of BPH, 12 samples of high-grade PIN, and 40 samples of prostate cancer were collected from patients at Viet Duc Hospital and Friendship Hospital. Total RNA was extracted from BPH, PIN and prostate cancer tissues; cDNA synthesis by reverse transcript - polymerase chain reaction (RT - PCR); HIP transcript determination using semi-quantitative PCR. Results: There was significant difference in HIP transcript levels. HIP transcript was very highly up-regulated in the prostate cancer tissues. The up-regulation of HIP transcript was lower in PIN, and lowest in BPH. HIP transcript levels in benign samples were 1/2 and 2/3 compared with cancer and PIN samples, respectively (P< 0.05). These indicated that up-regulation of HIP transcript may be an early event in tumorigenesis. Conclusions: Levels of HIP transcript were different between tissues of prostate cancer, PIN, and BPH. HIP may be a marker for pre-cancer of the prostate.

Background: Heparansulfate Interacting Protein (HIP) is up-regulated in various human cancer cell lines at both transcript and protein levels. HIP expression is related to the differentiation status and cancer development. Objectives: To determine HIP in benign prostatic hyperplasia, prostatic intraepithelial neoplasia and prostate cancer tissues. Materials and method: Western blot method was used to determine HIP expression in 3 different types of prostate tissue, including 11 prostate cancer samples, 2 benign prostatic hyperplasia samples and 11 prostatic intraepithelial neoplasia samples. Results. HIP was particularly up-regulated in prostate cancer and prostatic intraepithelial neoplasia, indicating that up-regulation of HIP expression may be an early event in tumorgenesis. Conclusion: The expression of HIP was different between cancer, prostatic intraepithelial neoplasia tissue and benign prostatic hyperplasia. HIP may serve as a prognostic marker for prostate carcinoma.

Background: Hemophilia A is a genetic bleeding disorder that results from a deficiency in factor VIII. The prevalence of Hemophilia in Vietnam is rather high (2/34830 people) and Vietnam has high usage demand for factor VIII in the treatment and prevention of the disease. Therefore, it is necessary to study and produce recombinant blood \u2013 coagulation factor WIII. Objective: To clone successfully A1A2 and A3C2 gen fragment encoding factor VIII. Subject and Method: Amplify A1A2 and A3C2 gene fragments by PCR from human cDNA. PCR products were ligated into cloning vector pQE \u2013 30UA. Recombinant plasmids were transformed into E.coli DH5 alpha host strain. Inserted A1A2 and A3C2 gene fragments were checked by PCR and restriction enzymes. Result: Successfully amplifying functional gene fragments encoding factor VIII using specific primers. Conclusion: Obtaining pQE \u2013 30UA vector carrying A1A2 and A3C2 fragments encoding factor VIII. This is the premise result for the next studies on synthesis of recombinant factor WIII and application of genetic therapy.
