Investing on quality, quantity, neurophils and mucin test for 30 joint fluid samples collected from 30 patients with various arthral conditions, comparing to control subjects in Arthral-Skeletal Department of Bach Mai Hospital from Mar. 2002 to Jun. 2002. Results: There were changes in macroscopy: the volume of joint fluid was more than 5ml, light or dark yellow, lack of transparency, completely reduced viscosity. Test mucin was positive range from (++) to (+++), counts of white blood cell and neurophil increased. It was suggested that mucin and joint fluid cell studies can add for diagnosis of some arthral conditions.

To find prevalence of orthostatic hypotension (OH) in elder persons living in community, blood pressure was measured in the supine position and after 1-2 minutes of orthostatist in 1286 elderly persons (499 men and 787 women aged 70.447.54 years). The results showed that the prevalence of OH in elderly persons living in community was 18.5%. There are not any significant difference in OH between men and women. Prevalence of OH in “very old” group (75 years old or more) was higher than in 60 - 74 years old group (30.4% vs. 13.8%). The hypertensive persons had the prevalence of OH higher than that of the normotensive persons.

1305 older persons living in communities were included in an epidemiological survey to investigate the risk factor for atherosclerosis. The results showed that prevalence of risk factors in the elderly was high: dyslipidemia (47.5%), hypertension (45.6%), smoking (26.9%), obesity (18.3%) and diabetes/IFG (12.1%). The prevalence of hypertension in rural area was higher than in urban area. Prevalence of dyslipidemia, diabetes/IFG and obesity in urban were higher than in rural area. There are not difference in prevalence of hypertension, diabetes/IFG and obesity between men and women.

173 patients admitted to the Respiratory Department of Bach Mai Hospital between 12/2000 to 7/2001 were underwent flexible bronchoscopy. The results showed that the rate of bronchial cancer was highest (57.8%). Among that, the rate of central bronchial cancer was 87% and the rate of periperal bronchial cancer was 13%. Lung tuberculosis was 8.1% and chronic bronchitis is 9.8%. Bronchoscopy was useful in diagnosing some other conditions such as asthma, sarcoidosis, laryngoptosis etc. Bronchoscopy combined with bronchial fluid aspiration produced high diagnostic value in bronchial tuberculosis. Rate of smokers in bronchial cancer patients was 60%. The higher level of smoking, the more likely to be suffered from lung cancer.

The cross-sectional desriptive study included 762 postmenopause women who lived in inner and suburb of Ha Noi city. The subjects were divided into 3 groups: 5 years or less of menopause, between 5 to 10 years of menopause and 10 years or more of menopause. All of them were overall examined. 206 women also were calcaneal ultrasound measured. The results showed that the rate of joint pain was 55.7%, increasing gradually with the years of menopause and more common in inner-city women. The rate of back pain was 68.2% and more common in suburb women.

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

Investigation of Pseuderanthemum palatiferum (Nees) Radik showed that fresh leaves were rich with mineral elements, especially calcium (875.5 mg%) kalium (587.5 mg%) and iron (38.75 mg%). Amino acids also occurred in large amounts, such as isoleucine (148.34 mg%), alanine (106.44 mg%), valine (99.73 mg%), leucine (84.15 mg%). The leaves extract was non-toxic to fish

Two phenolic compounds were isolated from the aerial part of Excoecaria cochinchinensis Lour. for the first time, and were determined by means of nuclear magnetic resonance and gas chromatography-mass spectrometry as 3,4,5-trihydroxy-benzoic acid (gallic acid) and its ethyl benzoat derivative: 3,4,5-trihydroxy-ethyl benzoat

Melaleuca alternifolia Cheel was acclimatized from Australia to grow in Vietnam. Samples were collected from various provinces, and the analysis of M. alternifolia Cheel was performed by means of gas chromatography-mass spectrometry to afford four different chemotypes with terpinene-4-ol (34.08-40.44%), terpinelene (39.47-60.34%), 1,8-cineole (71.23-77.54%) and terpinolene (34.89-38.30%) plus 1,8-cineole (30.84-35.26%) respectively as main components of the essential oil

The quantitative determination was performed on atomic absorption spectrophotometer. Herbal remedy Codonopsis pilolusa (Franch.) Nannf., yeast extract and SMC preparations (liquid and powdered) were proved to contain calcium, magnesium, iron, zinc, manganese and copper. Selenium was also found in yeast extract and SMC preparations. The quantative results were given
