In the first 7 months of 2002, the malaria status in Bac Can province were rather stable: the malaria incidence reduced 16%, there was no malaria outbreak, the morbidity due to malaria reduced. These activities to practice the malaria prevention plan in Bac Can: supervising malaria epidemiology, preventing vecto, propagating healthy education, educating training, systemizing report information, using materials expenses. The result of survey quality malaria prevention activities in Cho Moi and Mach Thong districts were low: Bach Thong district examined newly supplement smear pills, in which smear pill had more mistakes; Cho Moi district treated correctly 50% of checked case history

Fifty three of normogravid - normotensive women who subsequently developed pregnancy - included hypertension demonstrated an increase in diastolic blood pressure at least 20 mmHg when turned from the lateral recumbent to the supine position, between twenty eight and thirty six weeks of gestation. Conversely 95.8% percent of women who did not demonstrate such a rise in diastolic blood pressure when turned to supine position did not become hypertensive during that pregnancy. The results demonstrated the high validity of this method as follow: the sensivity of predictive value: 65%. The specificity of predictive value: 93%, the positive predictive value: 53%, the negative predictive value: 96%.

59 batches of purified tetanus antitoxin and 20 batches of anti-rabies serum (1997-2001) produced at IVAC Nha Trang were tested for: pH, total nitrogen, merthiolate content, sodium chloride content. In general, all the batches met the minimum requirements of the manufacture. However in order to improve the quality of the sera additional requirements should be set up

In this paper, a total of 467 species of medicinal plant, belonging to 109 families have been reported used by Yao (Dao) ethnic minority living in Bavi National Park’s buffer zone. Forty-four species have been identified as frequently used and twenty-nine species of high priority for conservation. Principal Components Analysis revealed that abundance of medicinal plants and number of medicinal plants listed in the Vietnamese Essential Drug List are negatively, significant correlated to PCA1 which dominated by altitude, slope, vegetation disturbance, number of tree species, canopy height of trees and grass cover. While number of high priority conservation and number of frequently used medicinal plants are positively correlated with PCA1.

Introducing some advantages of cardiac ultrasound (through chest wall and trans-esophagus) in diagnosis of mitral stenosis. In Vietnam, Some kinds of cardiac ultrasound were applied since 1973 including M-mode ultrasound, 2D ultrasound, Doppler, and color ultrasound. Internal treatment and surgical treatment (including in closed or opened cardiac surgery, percutaneous mitral balloon valvotomy) are very efficient

Composting is the transformation of organic waste through decomposition by microbacteria into soil-like material. Organic waste used in composting is from agricultural waste like vegetables from farms, markets, restaurants, hotels, processing plants. There are two techniques of composting: (1) composting of waste pile with air supply system, (2) natural composting with air supplied by tossing the pile. Composting is used widely in other countries to manage waste. Composting not only results in a soil-like material as a good fertilizer but also it reduces a consiferable amount of waste.

The results of a retrospective study of epidemiological surveys was conducted by National Iodine Deficiency Disorder Control Program and periodic surveys were conducted by the Centre of Preventive Health of An Giang in 1998, 2000 and 2003, showed that the coverage rate of households consumed salt with an iodine concentration of more than 20ppm was 29%, 52.9% and 76.5%, respectively. The median urinary iodine concentration was 1.8mlg/dl, 4.4mg/dl and 5.7mg/dl, respectively. The prevalence of goiter in children age 8-10 years was 20.5%, 12.8% and 6.1%, respectively. In 2003, there were still 71.5% of households situated in the iodine deficiency area in An Giang province. The main reasons make people have not used iodised salt are habit of using normal salt; iodised salt is not available and affordable. Although knowledge about the benefit of iodised salt for preventing endemic goiter is 89.4%, knowledge of using iodised salt for preventing creatinism is low (40%).

The study was carried out on 50 patients with anthracosis treated from from 1stJanuary 2001 to November 31st 2001 at Thanh nhan hospital.anthracosis was the most frequent to be met among the whole occupational dust-related diseases. The patients have been got diseases, essentailly related to the long duration in contact with various dusts or by having histories that easy to be got diverse diseases of respiratory tract. The commonest symptoms in anthracosis are dyspnoea 70%, cough 62%, sputum excretion 40%, modifications or pulmonary and X-rays, eletrocardiogram, especially respiratory function deficiency. Diseases and complications frequently met of anthracosis were bronchitis, pneumonia, cardiac insufficiency, chronic cardiopulmonary diseases, cardio arrhythmia, pulmonary infarction and hemoptysis

To survey the basic measurements of urodynamic as cystometry, uroflowmetry, electromyography, urethral profilometry. Currently, it may be to combine measurements each other or urodynamic with image diagnostic technique in order to have comprehensive consideration, more accurate on lower urinary tract function: To combine with cystometry, uroflowmetry and electromyography, detrusor pressure measurement, to combine with cystometry and observe reflection of light of cystoids under fluorescent screen, video-urodynamics

Varicocele is a dilatation of plexus venosus in the spermatic cord. It rarely occurs before the age of puberty, but 15% of male teenager experienced varicocele (the rate is relatively high). This rate is higher when surveying data of male infertility (35% of primary infertility patients, and 75-81% of secondary infertility patients had experienced varicocele). Varicocele may affect both sides, but 90% of cases occurred in 1 side and among them 90% were in the left side. Microsurgery is a treatment with high rate of success
