Our research was carried out on 133 occupational carbon monoxide exposed workers in a metallurgical factory. The results showed that carbon monoxide concentration in some working places was higher than the allowance limit from 1.4 to 5.3 times. 77.2% indoor environment was polluted by substances coming from factory. This pollution had influenced on the health of 35.3% of workers (influence on nervous, circulatory, respiratory, digestive systems and anemia,..) 16.5% of the cases suffered from occupational carbon monoxide chronic clinical poisoning. The occupational acute carbon monoxide poisoned anamnesis at the factory was 7.3%.

The investigation was done in 74 occupational carbon monoxide exposed workers in a coke factory. The result showed that carbon monoxide concentration in some work places was higher than the allowable limit from 1,2 to 5 times. 70,3% workers' indoor environment was polluted by substances coming from factory. These pollution had influence on the health of 47,2% workers (influence on nervous, circulatory, respiratory, digestive systems and anemia etc.). 1,4% of the cases suffered from occupational carbon monoxide chronic clinical poisoning.

Wedelia chinensis (Osbeck) Merr. (Synomyme: W. calendulacea Less.) was commonly used in folk medicine for the treatment of furunculosis, phlegmon, impetigo, cystitis. Two other plants, namely Tridex procumbens L. and Phyla nodiflora (L.) greene were often confused with W. chinensis. The study presented detailed descriptions of the morphological, anatomical and palynological characters of the three species, offering an easy distinguishment of the plants

Wedelia calen-dulacea Less. (Asteraceae) is well known for its antibacterial, demulcent and antifebrile properties, it is a traditional medicine which wild growing in many areas in Viet Nam. The researchers firstly study its chemical composition. Results of the chemical analysis show that: The plant contains flavonoid, alcaloids, coumarin, triterpenoid saponins, tanin, sugars, fat, sterols and carotenoid. The content of total flavonoids is about 1% (on dry basis), at least 11 spots on chromatogram. The content of total saponins is about 12% (on dry basis). The analysis with 3 different solvent systems revealed at least 15 spots on chromatogram. Some of the spots can be shown with both flavonoid and coumarin reagents, these are tentatively called coumestan components.

The 1:1 fluid extract of Wedelia calendulacea Less. aerial part was used for the evaluation of the plant hepatoprotective effect. The results of the pharmacological studies included: (1) Oxidative activity: 83.1% (in vitro), (2) Decrease of malonyl dialdehyde in mouse liver: 25.1%, (3) Decrease of the serum glutamate pyruvic transaminase level: 34.1%, (4) Decrease of the concentration of bilirubin in mouse serum: 10.4%, (5) Increase of the bile flow in mice: 88.8%. Conclusion: W. calendulacea had a good hepatoprotective effect in mouse model.

The Wedelia calendulacea Less. in Van Dien area, Ha Noi, rats of the body weight of 20-22g were divided into 3 groups. In order to use Wedelia calendulacea Less. in treating liver diseases, fractions from the plant have been studied pharmacologically. This paper presents the method of extraction of oleanolic acid and results of its anti-oxidative effect. The studies have revealed that amount of liver MDA of the treated mice decreased by 44.8%, and that of serum GPT decreased by 26.3%. These results show that oleanolic acid do take part in the hepatoprotective activity of the plant

Background:Asthma is a chronic infectious disease of respiratory which affect to health, study, labor and social activities. It can be occur at all age, the rate of incidence of this disease and mortality is increasing. Objectives:This study aims to learn about the clinical features and treatment results in children with asthma admitted into pediatric department, Thai nguyen Central Hospital. Subjects and method: A retrospective study was carried out on 65 asthma children who admitted to Asthma children of Department of Pediatrics, Thai Nguyen Central hospital in order to find the frequency, risks factor, clinical and management ofasthma from 1st January 2004 to 31st December 2006. Results:The asthma rate was 0.81 % among total inpatients and 2.87% among total patients admitted into the Respiratory Department. 30.8% of patients aged from 3 to 6 years old without sex predominance. The children were admitted more often in April, May, September, October and November. Personal and family history of asthma was seen in 70.77% and 35.38%, respectively. The common signs were: cough in 93.9%, coryza in 89.2%, intercostal retraction in 87.7%, wheezing in 80.0%, dyspnea in 66.2%. 4. Management: Bronchodilatator in 100%, antibiotics in 95.4%, corticoid in 76.9%. Improvement was seen in 98.5% and death in 54%. Conclusion: Drugs to lessen cough, phlegm and infusion were not encourage in asthma treatment.

Introduction: In Vietnam, the andrology field has been developed in recent years. Some studies have indicated the reasons for male infertility. Amongst them, the most common reason is abnormal semen. Asthenozoospermia rate was found at a higher ratio in abnormal semen analysis. \r\n', u'Objectives: To identify the characteristics of sperm and concentration of FSH, LH and Testosterone in serum; and the association between the sperm morphology and sperm motility as well as the concentration of FSH, LH and Testosterone in serum of asthenozoospermia men. \r\n', u'Subjects and methods: 90 asthenozoospermia male partners of infertile couples. The semen was analyzed at the Laboratory for Tissue and Embryo Preservation, Hanoi Medical University. The hormone concentration was measured by the Automated Chemiluminescence System ACS 180. \r\n', u'Results: The mean semen volume: 3.0 \xb1 1.1 (ml); sperm density: 104.7 \xb1 86.7 million/ml; rapid motility rate: 5.9 \xb1 6.4 (%); sperm vitality rate: 67.4 \xb1 20.1 (%); normal morphology rate: 14.4 \xb1 6.9 (%). In serum, the concentration of FSH was 5.3 \xb1 2.5 lUlL; LH: 4.1 \xb1 1.8 IU/L. Testosterone: 18.3 \xb1 9.4 nmol/L. Conclusions: Among the studied asthenozoospermia men, normal semen volume was found at 91.11 %; normal sperm vitality parameter: 84.4%; normal morphology parameter: 45.56%; normal level of FSH concentration: 47.7%; normal level of LH concentration: 26.66%; normal level of Testosterone concentration: 78.89%. There was a strong association between the sperm morphology and sperm motility as well as serum Testosterone concentration. \r\n', u'

Background: In Vietnam the juxta-articular soft tissue diseasesare very popular, but they have not been studied yet. Objectives: (1) Describe clinical feature of some juxta-articular soft tissue diseases (tendinopathy) (except periarthritis of the shoulder). (2) Determine the risk factors of these diseases. Subjects and method:118 patients with juxta-articular soft tissue diseases. Diagnosed following the standard criteria and treated in Rheumatology Department Bach Mai hospital (Hanoi - Vietnam) in the period from December 2005 to August 2006 There was a prospective descriptive method of study.Results:(1) Clinical feature of some juxta-articular soft tissue diseases: average age: 50.2 \xb1 10.4 years, female/male ration: 4:1, the most frequent clinical forms: Tendinosis of the Elbow (Tennis Elbow) (25.4%), de Quervain\u2019s tenosynovitis (22.9%), trigger finger (17.8%), Pes Anserine Bursitis (23.7%). Clinical symtoms: pain intensity: average VAS score: 5,8 \xb1 1,3 mild and moderate limitation of movement, inflammatory signs were not evident: Mild swelling (55%), redness, increase of local temperature (4-5%), pain character: Tendinosis of the Elbow and Pes Anserine Bursitis: permanent mild pain (73.6% and 68%), de Quervain\u2019s tenosynovitis and trigger finger: pain with irrdiation along the tendon (100%). (2)The risk factors ofthese diseases: manual and repetitive work, care of children (74%), middle age (73%), female (80,5%), osteoarthritis (21.2%), diabetes associated with trigger finger (19%).Conclusion: (1) The juxta-articular soft tissue diseases were seen at middle age, with feminine preponderance, moderate pain, not evident inflammation. Clinical forms: the prevalence of each group odd diseases (Tendinosis of the Elbow, de Quervain\u2019s tenosynovitis, trigger finger, Pes Anserine Bursitis) are quite eqiuvalent. (2) The risk factors of these diseases: manual and repetitive work, care of children, middle age, female, osteoarthritis, diabetes.
