In this study, 48 long-term exposed people with polychemicals (the male/female ratio is 1/3, the age from 23 to 44): such as organic and iso-organic acids: benzene, toluene and their coequals were investigated. 17 normal people not exposed with polychemicals as the control group. Results were shown following: quantity of erythrocyte was lower than control group but not significantly. Leucocytes especially neutrophils reduced significantly (p<0.001). 15/48 cases (30%) appereared lymphoblast. There is no difference in platelet between studied group and control group

Study on 48 people, of whom 16 are male and 32 are female, from 23 to 44 years old. They were long exposed with poly-chemicals, such as organic and iso-organic acids: benzene, toluene and their coequals. The parameters have been used: phagocyte capablity and phagocyte index of neutrophils; E, rossett formed T cells. The results showed that: Phagocyte capability and phagocyte index of neutrophils decreased significantly comparing with control group (p<0.001)

20 patients with acute leprosy, 12 patients with chronic hepatitis, 34 patients with acute myelogenous leukemia, 48 patients with pharynx cancer. 31 normal healthy persons in the control group. Immune-complexes were fixed quantity by 2 methods: precipitating the immune-complexes with PEG having molecular weight 6.10¬3 and better method. Immune-complexes (+) were identified on acute leprosy, chronic hepatitis and acute diseases with the ratio of positive differences depending on disease, stage and the character of applying technique

115/400 Muong minority pupils of boarding school in Hoa Binh province, all studied subjects have 3 genarations of Muong minority (grandparents, parents and themshelves being Muong minority), from 15 to 19 years old. Using Sero check product of USA to examine the ratio of HBsAg. Results: 19.05% of the boys having HBsAg(+), 13.38% of the girls having HBsAg(+). So the ratio of HBsAg(+) in girls are lower than in boys but it is not significant. The ratio of HBsAg(+) at the age of 15 is 19.61%, the age of 16-17 is 14.74% and the age of 18-19 is 16.67%, there is not significant between groups

Background: The minor salivary gland biopsy is an important diagnostic criterion of Gougerot-Sj\xf6gren syndrome. Objective: To describe histopathological characteristics of minor salivary gland of Gougerot-Sj\xf6gren syndrome combined to rheumatoid arthritis. Subjects and method: A prospective, descriptive, cross-sectional study included 108 patients with rheumatoid arthritis, who treated at Department of Rheumatology of Bach Mai hospital, from 1998 to 2003. The patients were divided into 2 groups: 50 patients with Gougerot-Sj\xf6gren syndrome and 58 patients without Gougerot-Sj\xf6gren syndrome. Results: Characteristics of minor salivary gland biopsy were lymphocytic infiltration of minor salivary glands (96%) with various distribution: periductal (86%), periacinic (72%), perivascular (36%). 78% of cases were plasmocytic infiltration, with periductal distribution (70%). 82% of cases were 3, 4 stages according to Chilsom clsssification. 67.5% of cases had ductal abnormality, glandular atrophy (62%), vascular edema (58%). Conclusion: Incidence of 3, 4 stages according to Chilsom classification was 82% in rheumatoid arthritis patients with Gougerot-Sj\xf6gren syndrome.

109 patients (male: 60) with ages of 18-80 suffering the previous untreated acute haemorrhoid (congestive symptoms, no complication) administrated Ginkor fort at dose of 2 tablets x 3 times within the first 2 days and 2 tablets x 2 times a day within following 4 days. The results have shown that Ginkor fort had a rapid analgesic effect (55% of patient with pain free). The drug improved obviously the bleeding, even no bleeding (87.1%). 78.9% of patients had no pain at the sixth day. 94.5% of patients had obvious pain relief or bleeding reduction. There was a difference of these between the second day and sixth day. The itching, desire for movement and leakage improved among 80% of patient in the sixth day. The rate of good tolerance of Ginkor fort was 97.2%.

A prospective study of ambulatory CO2 laser hemorrhoidectomy. 295 consecutive patients (147 males, 148 females), mean age of 39 years (18-72), 97 cases of them (41 circumferential hemorrhoids, 56 piles) were strict follow-up from 3 months to one year. All had been operated by “restricted and pile-size hemorrhoidectomy” technique and performed with CO2¬ laser. Less operative bleeding (about 90% <20 ml), operating faster (average: 23.58 min), less painful (78.4% degree A + B), none post - op, hemorrhage, mean wound healing within 4 weeks, none late complication (anal fissure, fistula, deformity...) and recurrence. Hemorrhoidectomy using CO2 laser and author’s technique is safe, effective and no-hospitalization.

Purpose: Estimate the results of circumferential haemorrhoidectomy with laser CO2. Methods: A prospective study of 228 patients with circumferential haemorrhoids. All had been operated by "restricted and pilesize heamorrhoidectomy" technique and performed with laser CO2. Follow up 1 year to over 5 years. Results: less operative bleeding, operating faster, less post-op, painful and heamorrhage, mean wound healing within 24 days, short hospitalization, none late complication (anal fissura, fistula, whitehead deformity...) and recurrence. Conclusion: Circumferential heamorrhoidectomy using laser CO2 and author's technique is safe, effective and quick recover.

Our study were carried out on 5 patients (3 males, 2 females, the average age was 37.6) in order to evaluate primarily the regime of anti-retrovirus with didanosin and ididavir on 5 HIV patients at some stages of disease. The obvious effectiveness of combination found in the first 3 months, the tolerance was rather good, therefore the drugs can be used for along time. However, the results were satisfactory when using early and the patients were not addicted

The aim of present study was to assess the prevalence of Helicobacter pylori infection in Dak Lak province patients with advanced gastric cancer, and to identify factors that may affect the detection of H.pylori in patients with gastric cancer. 56 patients with advanced gastric cancer were treated by gastrectomy. For the detection of H.pylori, both biosy specimens and sera were collected from the patients. A strong association was shown between H.pylori and both intestinal and diffuse type gastric cancer. Antibiotic intake in the month before operation, the site of collection of biopsy specimens, and tumor size were indentified as factors that may reduce the CLO test. These data provide supporting evidence of the prevalence of H.pylori infection in gastric cancer and indicate that, in certain circumstances. CLO test evaluation of H.pylori infection in gastric cancer cases may be less reliable than serological evaluation.
