Biochemical characteristics of B. subtilis Du, B. subtilis NT, B. subtilis ATCC 6633 were primarily the same, but their size was smaller with small colonies, R form and opaquely white color. 72 hours was culture duration for obtaining highest amount of amylase in B. subtilis ATCC, while in B. subtilis NT and B. subtilis Du – 96 hours

In the last 11 years recently the contaminated rate was very low (291/6382 samples). 0.45% and decreased dramatically in the past 3 years (2000-2003 period). The most common contaminated germs were primarily gram(+) bacteria (60% - 195/320 samples). 4.6% of samples were contamined with fungi (15/320), which should be erradicated completely

The remedy “dang sam” has been used commonly in the traditional oriental medicine to reinforce “khi” (vital energy). Two species of “dang sam” were found in Sapa city (Lao Cai province): a wild one and an acclimatized one. In the current study, the botanical characteristics of the wild “dang sam” were described, and the plant was identified as Codonopsis javanica (Blume) Hook f. The acclimatized “dang sam” also exhibited the characteristics of the Codonopsis genus, and has been planned to be the object of a further study in the future.

Both ethanol extracts of the bark and leaves of Schefflera elliptica (Blume) Harms (Araliaceae) showed antistress effect on mice at the oral doses of 158 and 167 mg/kg body weight, respectively. The bark proved to be more effective than the leaves, and their efficacity increased with the doses. Both extracts possessed in vitro antioxidant activity at the concentrations of 50-100 mcg/ml, the bark also being more effective than the leaves. The total saponin extract of the bark exhibited antioxidant effects at the levels of 5-25 mcg/ml. So, saponins might be the chemical constituents determining the antioxidant activity.

This paper introduced some techniques of molecular biology in the diagnosis of tuberculosis including polymerase chain reaction (PCR), RFLP, KT, NASBA, M. tuberculosis AMTDT, KTLCX, LCR Abbott, TMA, QB... and biochemistry and microbiology such as analysis of specific lipid components and cell septal of M. tuberculosis by chromatography and determination of fatty acid in the cell septal of M. tuberculosis

The authors have examined the biochemistry activity of the hospital during the past 4-5 years. The numbers of the tests have been raising from 52,000 to 140,000/year. The different kinds of tests have been raising from 55 to 90. The quality of the tests is poor; now 90% of them give high precise results.

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

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
