Diagnostic curettage has for many years been the method of choice to diagnose endometrial cancer in women with postmenopausal bleeding. In fact, approximately only 10% in this group of women will be diagnosed with endometrial cancer. This study used endometrial thickness as measured by endovaginal ultrasonography as an indicator of endometrial abnormality. The histopathologic diagnosis obtained at curettage is used as the gold standard. 74 women were included in this study. Endometrial cancer was not found with the endometrium= 5 mm thick. The mean endometrial thickness in those women with endometrial cancer was 13.72+/- 8.09 mm compared with 4.3 +/- 2.3 mm in those women with benign endometrium. If the cut off limit for endometrial cancer and hyperplasia was 5 mm, the sensitivity was 100% the specificity was 71.2%, the positive predictive value was 60%, the negative predictive value was 100% and the Kappa ratio was 0.6%. If this limit had been used in this study, 70% of the curettage procedures could have been avoided.

Simultaneous endometrioid carcinoma of the endometrium and ovary was also called 'endometrioid systematic carcinoma'. This disease was not common with the rate of 5.2% of all endometrial carcinomas. This malignant epithelial neoplasm was presented with high differentiation (Grade 1), and it was often detected at early stages (0; 1A: 1B). Their common symptoms were abnormal metrorrhagia associating with ovarian cyst in young women having low parity. The determined diagnosis based on macroscopic and microscopic description, which could be a key significance in classification of this special lesion

A prospective study was carried out to investigate clinical and paraclinical findings of the congenital megaureter in children and the results of its surgery from April 1992 to July 2000, 39 patients with 49 ureters has been operated. Two most common clinical findings include urinary tract infection and urinary tract obstruction. Ultrasound could detect a megaureter in all patients. Urography showed a typical finding (radicÌle) in 6.1%. A renal function was impaired in 77.6%. Treatment included ureteral reimplantation in 89.8% and nephrectomy in 10.2%. 86.2% patients had a good results on the follow-up.

There were many events and achievement of the health sector. The strengthening and cosisodilation of the health network and primary health care contributed importantly to the people health protection and care. The year of 2002 play an very important role in strategy of health activity during 2001-2010. It should develop the obtained achievement, concurrently find the basic lesion and propose solutions for the health activity.

Mentha piperita L.Mentha piperita L. was collected from Sapa, Lao Cai province and cultivated at Co Nhue – Tu Liem – Ha Noi. The content of the essential oil in fresh branches of this peppermint was about 0.16%. Its green yield is 1.85-2.10 Kg/m2. First time in Vietnam, the chemical composition of peppermint oil was analyzed by GC/MS and 43 constituents were identified. The main constituents were L-menthol (47.60%), menthol (24.10%), menthofuran (6.07%) and 1.8 cineol (5.55%), pulegone (4.22%). Base on these data. The quality of Sa Pa peppermint oil is good as one from native origin. Peppermint collected from Sa Pa enrich the gene source of medicinal plant in general and particularly the gene source of essential oil plant group of Vietnam

This randomized, placebo-controlled clinical study evaluated the efficacy of lamivudine in 44 Vietnamese patients with histologically documented chronic hepatitis B for one-year. The patients were randomly assigned to receive 100 mg of lamivudine (22 patients) orally once daily or placebo (22 patients). The patients underwent liver biopsies before entering the study and after completing the assigned treatment regimen. At the end of therapy, the percentage of serum HBVDNA negativation was higher in the lamivudine group (86.4%) than in the control group (22% P<0.05). The rate of HBe/antiHBe seroconversion was statistically different between 2 groups (35.2% in the lamivudine group compared to 12.5% in the controls). 95.5% of the patients received lamivudine had normal alanine aminotransferase levels (versus 18.2% in the placebo). Median change in HAI score was >2 points of improvement versus placebo. Lamivudine is less side effects, safety, and favorable

This paper presented a study on the dynamic of essential oil accumulation in Japanese mint SK33 (M. arrvensis L.) and the influence of storage time on its quantity and quality. This mint was cultivated at Co Nhue experimental station, Tu Liem district, Ha Noi City between 2000 and 2002. The results showed that during the vegetation and development process, the essential oil content in the plant gradually increased and achieved maximum at first branch flowering stage and reduced to minimum at the end of flowering stage. The menthol content in essential oil of Japanese mint SK33 reached the highest value at full flowering stage (81.79%). The best harvest time for this mint is from the beginning flowering stage to full flowering period. After harvesting the whole plants can be stored during 20 days without the change in content and quality of essential oil

44 patients of chronic B hepatitis are divided into two groups of 22 patients. The one is treated with lamivudine (Jefflix) 100 mg daily in 12 months continuously and the other with usual vitamin and liver tonics. Results showed in 72.7% patients of lamivudine group, the indices of histological activities were improved (through Knodell score), while in controlled group – 31.8% and over the half of this group these indices worsened. Thus, lamivudine has got good effect

From Aug-2000 to Aug-2003 at HCM City Blood Transfusion and Hematology hospital, 31 cases of endoscopic splenectomy were studied to evaluate the effect of this surgery to treat chronical immuno-thrombocytopenic purpurea once corticotherapy and immunosupressive therapy failed. Results showed that one year after splenectomy, 64,52 – 76,92%, and 2 years after, 50% of cases had had completely positive response. There was absolute failure in 38,7% of cases within 3 first months, but from the 4th month, there was no relapse case. A half number of patients with failed splenectomy had had quick response to corticotherapy more.The duration of treatment was short, endoscopic splenectomy was safe. There was no death. No case of blood transfusion was needed. There were no complications
