40 patients with bronchial asthma in Bach Mai hospital from 6/1998 to 5/1999 and 31 healthy people without allergy. Methods: finding the allergic history and skin test. The results: 52.5% of patients had his own allergic history; 42.5% of patients had a family history; 37.3% of patients had positive skin tests to foreign bodies of house dust mite; 32.5% of patients had allergic antibody against foreign bodies of house dust mite was more 30%. Among methods of specific diagnosis of allergy, there was a close relation between skin test and reaction of decomposition of mastocyte.

Loranthus parasiticus (L.) Merr. Loranthaceae (Vietnamese name is Tang ky sinh) was a traditional medicinal herb for treatment of back pain, hypertension, lack of sleep, etc. The chemical analysis confirmed the Loranthus parasiticus (L.) Merr. extract contained flavonoids, adjuvant heart glycosides, antraglycosids, tannin pyrocatechics and organic acids. Total flavonoid content was 0.57%. The pharmacological experiments in mice, dogs, isolated ears and isolated ileum of rabbits have revealed that the Loranthus parasiticus (L.) Merr. extract had antihypertensive, sedative and vasodilator effects. In addition, Loranthus parasiticus (L.) Merr. decrease ileum's mobility of rabbits and had a low acute toxicity

442 stool samples in 2 groups of population of Lien Vi commune, Yen Hung district, Quang Ninh provine were examined by Kato method. The infection rate of Ascaris, Trichuris, hookworm were 83.7%, 70.3%, 16.7%, respectively. The infection rate of Opisthorchis viverrini was 5.6%. 607 stool samples from primary and basical schools in the commune were examined. The results showed that the infection rate of Ascaris, Trichuris, Hookworm were 99%, 89%, 7.3%, respectively. The mix infection rate was 70%. It was found that most of the local people were using not standardized latrines. They have a habit of using untreated stool as fertilizer or habit of eating raw fish and their low awareness about disease prevention

Cranioplasty was proposed by Falloppio and later by Pare in 1634. During the last century, in particular, there has been a marked increase in the use of alloplastic materials for cranioplasty comprising a wide variety of materials: tantalium, titanium, acrylic, polyethylene, silicone and ceramics. The authors assess the efficacy of cranioplasty with carbon composite” intost-2” for cranial defect post brain injury was realized in the Department of neurosurgery of Saint-Paul hospital. Methods: from 10/1997 to 11/2004 , 124 patients skull defect after operation of traumatic brain injury underwent cranioplasty with carbon composite “intost-2”. there were 103 males (82.33%) and 23 females (17.66%) whose average age was 27 years (rang 5 to 55 years). 74 patients (51.61%) had an operation for acute subdural hematoma with or with out brain contusion and penetrating brain injury. One hundred one patient (81.45%) had large defect (>5cm) while 27 patients (21.77%) had very large defect (>8cm). Results: the operation successful rate was 98.39% (122/124). there were two infections because of cutaneous necrosis need secondary cranioplasty. Conclusion: The cranioplasty with carbon composite “intost-2” had good result in spite of large defect.

The study was carried out on 400 pregnant women and 400 military candidates in Ha Noi in 2003 to evaluate sexually transmitted infections (STIs). The result showed that: HIV infection rate in pregnant women was high (0.75%) and in military candidate was 0.25%. Syphilis was detected at the same rate in two groups: 0.25%. Using PCR technique, the researcher detected gonorrhea and C.trachomatis rates military candidate group were very high (2.0% and 9.0%, respectively), and the rates in pregnant women group was low (0.0% and 1.5%, respectively)

Ultrasound cross-sectional prospective investigation on 16 patients with Dengue fever, showed that 15/16 cases, gall bladder wall thickness was a factor of prognosis, standard for patients with high risk of volume dropping shock related to kidney syndrome, 12/16 cases with abdominal cavity fluid, 7/16 cases there was perirenal collection of fluid, 3/16 cases of fluid subcapsular collection in the liver, pleural effusion. In addition, there may be large pancreas and spontaneous rupture of the kidney.

For the first time in Daklak, S. typhi strains were isolated from cases of suspected typhoid fever. MIC was investigated on 50 strains of S. typhi in Daklak from 1996-1998. The results were as following: All these isolated S.typhi strains were fully sensitive to common antibiotics (1g/ml for Tetracycline, Trimethoprim/sulfamethoxazole and 4 g/ml for Ampicillin, Nalidixic acid and the third generation cephalosporin (Ceftriaxone M.I.C=0.125 g/ml) and the fluoquinolones (Ofloxacin M.I.C =0.25 g/ml), especially to 16% of Chloramphenicol-resistant isolates (with M.I.C = 64 g/ml). This is a great difference to compare with S.typhi strains isolated in Northern and Southern in Vietnam. Concerning the plasmid profile analysis, from 50 strains of S.typhi, the results showed that: All these strains did not harbour any R-plasmid. 43 strains harboured a plasmid lower than 70 Md. 7 strains did not harbour any kind of plasmids.

Clinical retrospectative study of 328 cranial trauma patients treat at Hai Phong Viet Tiep Hospital from 1/1 to 31/12/2002, all patients put on computerized tomography, male/female rate was 4/1, there were many patients aged from 20 to 50, 78% patients suffer traffic accident. Indirect injury image in C.T was 45% and direct injury image was 46%. 25% patients weve intervene surgery. 5% patients were mortality

20 cases of uretral stenosis underwent an endoscopic investigation. Cutting endoscopically the stenosis was a simple technique with low cost and good efficacy in initial treatment, which could be applied in most of uretral stenosis cases excuding uretral fistula, infection and stenosis at a long segment. After operation, regular dilatation and examination were recommended.

The investigation was conducted at 30 communes health stations of zones II, III in 3 districts – Huu Lung, Cao Loc, Van Lang – Lang Son province. There were many shortenings in essential care and were not at a same level in various communes even in a same district. For a same commune, there were large gaps between various communes. The main causes of shortening were not the lack of resources, in term of quantity, but of management capacity. Among them, the non homogenous management not basing on the concrete condition of each commune, the negligence of quality standard are the most important
