Study on 41 pharmaceutical companies in Hanoi city from March 1999 to February 2000. The results: there was an average of 46 pharmaceutical companies of sixteen countries bought the biding documents and about 43% of those companies submitted the bid documents. At each International Competitive Bids, the average of prices of pharmaceutical drugs were correlative with that announced by UNICEF, however, there was still a case of the mean prices of pharmaceutical drugs were higher than that announced by UNICEF. The prices of pharmaceutical drugs were considered lowest, lower than the average of prices of similar products, which were imported into the Vietnam market and announced by UNICEF

Studying the effectiveness of irradiation on bone-marrow, the numbers of leukocyte, erythrocyte, hemoglobin of mice (25 normal mice and 35 mice treated by gamma irradiation with the dose of 600 rad/(100rad/day) (60 Co) showed that: Gamma irradiation reduced total of leucocytes, the number of different leucocytic (lymphocyte, granulocyte, mono and natural killer cells), the ratio of reticulocyte, number of mature erythrocyte and hemoglobin: Total of leucocytes (3,14 ± 1,58 in comparison with 13,45 ± 4,6); monocytes (0,05 ± 0,03 in comparison with 0,26 ± 0,13), lymphocytes (1,66 ± 0,36 in comparison with 6,34 ± 2,84). After gamma irradiation, the number of reticulocyte was 55%, mature erythrocyte was 73% and hemoglobin was 82%

Study on white mices with age of 6-8 weeks, 18-20g body weight. They were divided into 3 groups: group 1 (control group): 30 mices; group 2: mices were immunesuppressed by 200mg cyclophosphamid per one kilogram of body weight, being checked after 5 days of injection; and 300mg cyclophosphamid per one kilogram (200mg on the first day and 100mg on the fifth day) and it was checked after 10 days of injection (group 3). The results: immunesuppressed model implemented by intraperitonial injection of 200mg per one kilogram of body weight checked after 5 days of injeciton. These parameters were used to assign the immune function

Heterogenous transplantation of skin was studied on two strains of mice BALB/C and Swiss.The subjects were divided into various groups :normal group, cyclophosphamid (CP) inhibited group, cyclosporin A (CPA) inhibited group, and the group processed with DY1. The onset of reject phenomenon of the graft and the completed reject of the graft in the groups of mice using CP, CPA and DY1 were more delayed in comparing with the controlled subjects. The cell numbers decreased and the percentage of transformed cells also decreased in all groups using CP, CPA and DY1

The solid dispersion system (SDA) of dihydroartemisinine (DHA) with PEG 400, PEG 1540, PEG 4000, PEG 6000 and Tween 20, cremophor EL, PEG 400 stearate as cocarrier were prepared. the experimental results showed that the release rate of DHA from suppository base was greater than the semi-synthetic triglyceride base and the physico-mixture

Across-sectional study was carried out in infants, at 7 communes of Ninh Thanh district, H¶i H­ng province, from 1995-1996. The methods for data collection were Anthopometric measurements, dietary assessment by 24 hour food recall method, clinical examination, and interview of the mothers by close ended questionnaires. The results of the study as follows: (1) Poor nutritional status was accompanied by high prevalence of acute respiratory infections (ARI). Interview of the history of diseases showed that poorer nutritional status was higher prevalence of acute respiratory infection (ARI). (2) Mean of energy intake per child per day of the children who suffered from lower and upper ARI was significantly different from the health children. The energy intake was different among three groups which have different nutritional status, but no significantly. (3) Protein and lipid intake of the children suffered from lower and upper ARI were significant lower than the healthy children. (4) Children suffered from lower and upper ARI had vitamin A intake was significant lower than the healthy children. The mean of Vitamin A intake of children suffered from mild, moderate and normal was significant different from each other.

A retrospective study was carried out in 34 chronic myeloid leukemia patients, who were followed up from the beginning stage of the disease throughout natural history of the disease. The result shows the follows: the percentage of transformation into acute myeloid leukemia was 86.7%, the percentage of transformation into acute lymphocytic leukemia was 13.3%. The median length of chronic phase was 28.9 months. The median survival was 33.6 months (52.4% patients have survived more than 52 months). Main cause of death in chronic phase was emboli due to hyperleucocytic syndrome

The aim of this study is to examine the effectiveness of hydroxyurea in treating CML patients in chronic phase. The result of the research shows that the induction treatment with hydroxyurea with initial dose of 40-60mg/kg body weight daily radically improves hematological condition for CML patients in chronic phase. All patients (42 patients) reached hematological remission (33.3% patients reached complete remission), 66.7% patients reached partial remission WBC decrease from 193.9117.7 g/l to 10.16.0 g/l. Percentage of myeloblast, promyelocyte, myelocyte and metamyelocyte in peripheral blood decrease from 35.08.0% to 6.96.6%. Hemoglobin concentration increase from 86.119.0 g/l to 96.013.3 g/l, RBC increase from 2.90.7 T/l to 3.20.5 T/l. The follow up during the time of induction treatment shows that main hematological indicators have changed gradually when approaching normal physiological values

The study was carried out on 61 chronic myelo-granulocytic leukemia (CML) patients aimed to investigate the cytological features of peripheral blood. The results showed that all patients had laboratory features of normocytic and normochromic anemia (RBC counts: 2.8T/L +/- SD 0.59). All patients have increased WBC and platelet counts (WBC count: 210.5G/L +/- SD 101.0, platelet count: 624.3G/L +/- SD 431.9). The differentiated white cells showed all types of granulocytic cell (myeloblast 1.5%, promyelocytes 4%, myelocytes 15.5%, metamyelocytes 14.8%, band forms 7.1%, segmented neutrophils 44.9%, basophils 3.3%, eosinophils 2.4%, lymphocytes 5.4%, monocytes 0.1%) with the increase on absolute number and percentage of basophil and eosinophil. However, there was no elevation in myelocyte count compared with metamyelocyte count

The study aimed to investigate the changes in blood uric acid level. Participants were 61 patients with chronic granulocytic leukemia who were treated at the Central Institute of Hematology and Blood Transfusion between 9/1999 and 12/2000. Main findings: Blood uric acid level has increased in a significant percentage of patients: 35.9% of males and 36.4% of females have blood uric acid level of 529 and 423Mmol/l, respectively. Mean level of blood uric acid for whole group was 356 +/- 132Mmol/l for males and 281+/-129 Mmol/l for females. Blood uric acid level was not changed consistently with white blood cell count. However, there was a tendency of having higher blood uric acid level in the patients with higher WBC count. The symptoms of secondary gout were not observed in patients of this study
