All Flic genes of Salmonella typhi, S. paratyphi A, S. paratyphi B, S. paratyphi C, and S. typhimurium code for phase 1 of H antigen (H:1) (d, a, b, c and i antigen respectively). The genes were sequenced on Sanger's principle by automatic sequenser (ABI, 3100 Avant, Genetic Analyser). The primer pairs for the Salmonella species were designed on the basis of the collected sequences. The results showed that PCR with these primers can clearly differentiate the five Salmonella strains, especially between S. paratyphi B and S. typhimurium.

Studying rheography of 32 patients with cerebrovascular insufficient treated by artificial magnetic fields at Central Military Hospital from June to December 2002. Results: treating by artificial magnetic fields gave significant improvements on the rheographic index such as reduce of  time and normalization of /T ratio, increase of Ri index and cerebrovascular volume to normal levels; artificial magnetic fields also improved imagines of rheographic waves. These results demonstrated the improvements in regulation of vascular tonicity, and promoting blood flow at treated areas

A survey on the proportion of gallstone in 13,301 people who live in Thai Binh province. The incidence of common stone include gall-bladder stone, bile-duct stone and gall-bladder and bile-duct stone in which 1.9% in rural area and 3.4% in urban area. The proportion of gall-bladder stone in urban area is 3.16%, two times higher than its proportion in rural area: 1.42% (p< 0.001). Some risk factors of gallstone are elderly, male, low education, high body mass index and other jobs except farmers.

In the Department of Communicable Diseases Hospital 108, 41 patients with srub typhus were diagnosed by Weil-Felix assay and dipsticks ELISA(+) were treated. Among them 22 by chloramphenicol 50mg/kg daily and 19 by doxycycline 200mg/daily in 7 days consecutively. Clinically, the common symptoms of the disease were prolonged fever (100%) in combining with head ache 100%, muscle pain 78.4%, erythema 34.7%. Doxycycline and chloramphenicol were the most efficient medicine.

51 patients with cerebro-vascular insufficiency were treated at 108 Military Hospital from June to December 2002. These patients were divided into 2 groups: 43 patients in group 1 were treated by alternating magnetic field; 8 patients in group 2 were treated by placebo. Alternating magnetic field with 45mT intensity had improved the symptoms of cerebro-vascular insufficiency such as: the relief of headache, vertigo, decrease in psychological and neuro-vegetative disorder, the decrease of stress making the sleep better and improving intellectuality. Results: 95.35% of patients in group 1 had more relief; 4.65% little relief, the moderate days of treatment were 14.484.79. A negative getting in the placebo group had demonstrated an objectiveness of the results. The intensity of magnetic field using in this study was suitable and almost without side effect during treatment

40 severe recurent epistaxis patients were monitored by digital subtraction angiography at Cho Ray hospital, from October 2001 to October 2003. The results: traumatic carotico-cavernous fistulas 3 cases; related carotid arteries 3 cases: carotid artery ligation; Internal maxillary aneurysms 13 cases: embolization; Related ethmoid artery 2 cases: ethmoid artery ligation. The bleeding sites have not been found clearly on DSA 19 cases: 5 cases in of them have no longer bleeding after DSA and pulled pack out. The DSA is a very important therapeutic application and sometime it was used as definitive treatment

Assessment some plans, the harm factors for worker’s health as follows: micro - climate, compared to permissible standard, at all working places are over from 2.1 degree to 3.3 degree, the humidity of the air is in the limit, in general the speed of the wind is low and unhygienics. The physical factors: shinning is under the minimum level from 20-100 LUX, the concentration of dust is under the standard, noise is high. 900 workers (686 women) had been examined periodically. Results: The most common diseases as follows: odonto-maxial-facial disease (66,7%), ear-nose-throat disease (60.6%), gynecology disease (58.4%). In addition, muscle-bone-joint disease, ophthalmology disease, entero-gastrology disease, cardiovascular disease, resspiratory disease... are occupied significal rate (>20%).

At HungVương Hospital, 17-48 hours after birth, 58 newborn babies with fetal age of 39,5 weeks in average underwent a neurological examination. Results showed that in comparing with the original British cohort, Vietnamese newborns had got significantly lower scores in 10 out of 25 indicators, including almost relating to truncal tone. Among these studied subjects, the deficiency of long chains fatty acid was unsignificant, while this group of fatty acids was related strictly to the nerve, especially ophtalmic nerve. The relation between transketolase concentration with neurological status was not identified

Study on the incidence rate of cervical cancer on 1.122 women aged from 15 to 69 years old were interviewed and had a gynaecological examination in an urban district of HoChiMinh city. HPV DNA detection was performed using a GP5+/6+ primer-mediated PCR enzyme immunoassay. IgG antibodies against herpes simplex virus (HSV-2) were determined in blood samples using an ELISA assay. The results showed that: HPV DNA was detected among 10.9% of women in HoChiMinh city. 28 different HPV types were detected, the most common being HPV 16 (in 14 single and 18 multiple infections), followed by HPV 58, 18 and 56. A peak of HPV DNA detection in women below age 25 was found. Major risk factors for HPV DNA detection in the multivariate analyses were: indicators of sexual habits, most notably the presence of HSV-2 antibodies, nulliparity and the current use of oral contraceptives

Women of reproductive age seeking care at the Gynecology Clinic/Hung Vuong Hospital who were HSV-2 (+). Study subjects were randomized to receive either Hoa Long or placebo for oral administration in 12 days, then examined at 1, 3, 6 and 12 months after treatment. Findings: During the first year, 30.6% and 55.6% of the women allocated to HL and GD groups, respectively, had at least one episode of recurrent herpes. In addition, count and proportion of lymphocytes were higher in HL than in GD group. At 3, 6 and 12 months after treatment, CD 4 counts were 806.9, 701.2 and 800.1, respectively, for HL group, compared with 629.2, 584.2 and 629.3, respectively, for GD group. Similarly, CD 8 counts at 3, 6 and 12 months were 771.2, 614.7 and 824.1, respectively, for HL group, compared with 689.1, 489.3 and 596.4, respectively, for GD group. Among HSV-2 (+) women, Hoa Long increases CD 4 and CD 8 counts and reduces the recurrence rate of herpes during the first year after treatment
