Background: Bacteria are among the common pathogens in Vietnam and other developing countries. Antibiotics are effective in the treatment, but the antibiotics gradually become ineffective due to drug resistance of bacteria, especially in children. The study on influenza virus in 2001-2003 has resulted in preventative activities against the acute respiratory tract infections in children.\r\n', u'Objectives: Determine the root cause bacterial infections and often determine the extent of antibiotic resistance of common pathogenic bacteria isolated in Hai Phong pediatric Hospital.\r\n', u'Subjects and method: At Microorganism Department of Hai Phong pediatric Hospital from January 2003 to December 2004, 558 trains of common pathogenic microorganisms were isolated from 0 -15 year old children clinical samples such as: blood, pus, cerebrospinal fluid, urine, stool...These samples of isolated microorganisms were also tested on their sensitiveness to several antibiotics.\r\n', u'Results:Findings showed that the 3 most frequently recognized bacterier out of 11 antibiotic sensitive tested species were: streptococcus pneumoniae (20.61%), neisseria (18.1%), E.coli (15.95%); and the most resisted antibiotics included: Co-trimoxazole, Chloramphenicol and Ampiciline. The staph was resistant to general Chlora, phenicol, Co-trimoxazol, and also sensitive to cefotacim, Amikacin. In the bacillus bacteria tested were resistant blue latex all, only works with Amikacin.\r\n', u'Conclusion: Its also found that every kind of tested bacterium had got various levels of sensitivity to different of antibiotics.\r\n', u'

System suitability tests are an integral part of liquid chromatographic technique. They are used to verify the resolution (R) and reproducibility of the analysis to be done. HPLC method for assaying the related substances test of Cefaclor in raw material as well as in pharmaceutical dosage forms introduced to some pharmacopoeia such as EP, USP need to use Delta- 3 cefaclor as the internal standard to verify the suitability of chromatographic system. In case of lacking it to use, Cephalexin can be used as the internal standard in place of Delta-3 cefaclor. cell

During the period from 1993 to 1997, 126 poliovirus positive cases from samples of 1.098 acute flaccid paralysis patients of all provinces in the Northern region and 5 others in the Central region of Viet Nam have been identified. Among them 97 cases were caused by poliovirus type 1, 5 by type 2, 10 by type 3, 11 were identified as a multitype infection and 3 cases were the combination of poliovirus and enteroviruses. The antigenic properties of the poliovirus strains isolated have been studied using monoclonal antibody and polymerase chain reaction. The results showed that, 53 strains of poliovirus type 1 were identified as the wild-type virus, the rest were of Sabin-type virus. The wild poliovirus strains were then classified in to 2 groups by polymerase chain reaction - restriction fragment length polymorphism and sequencing methods. No case of wild type virus was isolated since 1994.

During the period from 1999 to 2000, 12 poliovirus isolates were obtained from acute flaccid paralysis (AFP) cases and 2 from healthy children who have been vaccineated with Sabin's oral polio vaccine. These isolated have been examined by PCR-RFLP. The results showed that the isolates were genetically identical to the regional Sabin's poliovirus strains

20 healthy male students from 20-25 years of age were studied on the changes of peripheral blood indexes after the exact Hegu laser He-Ne irradiation with intensity 130 mW/cm2 for 2 minutes/point. 10 (changed most clearly) of 20 these students were irradiated laser outside the Hegu (1cm far from the Hegu) as the control group. Before irradiating, after laser 10, 30 minutes, vein blood was taken to investigate the following indexes: RBC, WBC, HGB, HCT, MCV, MCH, MCHC, PLT, NEUT/1, LYMPH/1, MDX/1, RDW-SD, MPV, P-LCR. The results showed that PLT, WBC, LYMPH/1 reduced markly after 10, 30 minutes (p<0.05); there were no differences of the other (RBC, HGB, HCT, MCV, MCH, MCHC, NEUT/1, RDW-SD, PDW, P-LCR) between before and after laser irradiation. There was no differences between before and after outside-Hegu laser He-Ne irradiation; the time when the peripheral blood indexes changed more clearly is at the 30th minute after irradiating.

66 strains of heamophilus influenzae and 50 strains of streptococcus pneumoniae isolated from nasopharyngeal aspirates from 161 patients under 5 years old with ARI at the Viet Nam - Cu Ba Hospital, Ha Noi, during 9/1997 to 9/1998. 13 antibiotics were tested using the disk diffusion method. H.influenzae is still susceptible to cephalosporins, aminoglycosides, quinolones (95-100%). S.pneumoniae is also susceptible to cephalosporins (82-100%).

The aim of this study is to examine the antibody response in children who have been given oral poliomyelitis vaccine (OPV) produced by POLIOVAC Ha Noi. The study included 105 children under five years of age (32 in Ha Noi and 73 in Thanh Hoa). In Ha Noi children, the antibody response to each type and to all the three-poliovirus types was 100%. In Thanh Hoa children, the antibody response is poliovirus type 1 was 95.9%, to type 2: 93.1% to type 3: 93.1% and to all the 3 type 91.8%. Very high geometric mean titers against poliovirus type 1, 2 and 3 were evidenced

Outline on the antibiotic resistance of Streptococcus pneumoniae isolated during 1989-1995 in Viet Nam based on the data of antimicrobial susceptibility tests of NIHE and ASTS project. Comparing to the data from countries in South East Asis/India we found that: Str.pneumoniae is still susceptible to benzylpenicillin. B-lactams, macrolides, chloramphenicol. In many countries the reported incidence of drug-resistant Str.Pneumoniae has increased in the last year. The frequency and patterns of resistance vary in different geographic regions, countries and over different periods.

Phyllanthoideae is a primitive subfamily of Euphorbiaceae in Vietnam. This subfamily consists of 9 sorts, 17 genera and 192 species. Among which 46 species (23,96%) of the total 192 species used medicinally, most of which are in the Phyllanthus (10 species), Glochidion (9 species), Antidesma (7 species)...Among these, 60.87% are trees, the rest are shrubs and herbs, but no lianas. The most parts for treatment are leaves, and then the roots, the barks, the fruits and the whole trees.

In 2004, 10 poliovirus strains were isolated from 4 acute flaccid paralytic cases (AFP). All these poliovirus strains were confirmed as Sabin-like strains. 66 other non-polio enterovirus strains were also isolated including 29 echoviruses, coxsackie B viruses and 30 untyped enteroviruses. These virus strains were isolated from 489 stool specimens of 245 AFP cases. The results confirmed the free status of the stable sustaining poliomyelitis in Viet nam.
