Announcement of some initial results of making and investigating some particularizes of aspirin microfollicle. Percentage of asprin between theory and reality has remarkable change (+16.57 to -1.37). In generally, the microcapsules sample have low rate of Asp/EC, the aspirin microencapsulated rate is high and vice versa. Parameters of asparin percentage, rate of Asp/EC influence on asparin microencapsulated rate. Asparin capsule with EC box can be made with relatively high microencapsulated rate productivity. Aspirin capsule can last liberation of pharmaceutical material and give long-lasting effect in systems

Through 72 biopsy samples of stomach mucous membrane collected via endoscopy from patients seen at Trung Vuong Emergency hospital, experimenting rapid urease test and PCR were used to discover pathogenic H.pylori. Result: pylori test results are positive in 51.39% and negative in 48.61%, PCR test provided positive result in 54.17% and negative result in 45.83%. Pylori test is a rapid, simple and cheap. It does not required laboratory and is suitable for common situation of hospitals, medical centers in district level. PCR test is more sensitive so it should be deployed in big hospitals. Conformity rate between pylori test and PCR gains 86.11%, whereas inconformity rate between two tests is 13.89%

The stems and roots of Schefflera sp3 contained numerous fibers with cubic calcium oxalate crystals, lignified medullary rays. The leaves were covered with protective multicellular hairs in the shape of ramified candles. Saponin triterpenes, phytosterols, reduced sugars, tannin, coumarins, organic acids and uronic compounds were found in the leaves, stems and roots. Of the unsaturated fatty acids, oleic and linoleic acids were found in high amount in these 3 parts of the plant, but linolenic acids only in the leaves. The composition of oligoelements were similar in the 3 parts, except Cr only in the leaves, Ga only in the roots, whereas Ni, Mo, Sn and Pb only in the stems.

In the study, using the kinetic method for the examination of the dependence between the specific activity of the enzyme and the concentration of the enzyme itself in the combined reaction, the researchers have proved that the Ribonuclease (R.Nase) molecule of the black cobra (Naja naja) venom exits at least in two interconvertible forms with the difference in specific activity of almost one grade. These two forms are probably the different oligomers or configurations, temporarily named as the kinetic forms of R.Nase found in the black cobra venom.

From total dried extract extracted by methanol from roots of Nho dong (Morinda longisima Y.Z.Ruan, Rubiaceae) that was gathered in Chieng An commune, Son La town in Apr 2002, a compound called CP2 was isolated through chromatography. Spectral analyses showed CP2 was a coumarin named as Scopoletin. This was the first time Scopoletin found in root of Nho dong

Analysis on chemical contents of essential oil of Hybtis suaveolens (L) Poit collected in Ninh Thuan, Vung Tau and Phu Quocs showed that: 41 ingredients in essential oil of wild Hybtis suaveolens (L) Poit were identified by chromatography combining with mass spectrum. Hybtis suaveolens (L) Poit collected in others local but its compositions were rather similar. Major compositions was beta-caryophylen (30.35-44.27%) and 1,8-cineol (7.34-28.20%). In addition, some familiar monoterpens such as alpha - pinen, beta-pinen, sabinen, myrcen were in all three essential oils. Essential oil of Hyptis suaveolens (L.) Poit. had strong scent. With rather high content of sesquiterpen, essential oil of Hyptis suaveolens (L.) Poit. can be used as flavouring indicator in flavouring technology

The study was carried out in periods 1995-1999 and 2000-2003. The list included 199 drugs, in which there was 181 drugs belong to IV- Essential Drug List. From pattern of the disease of Khanh Hoa Rehabilitation Nursing Hospital determined through investigation during period 1995 to 2003 and selected pattern of 2000-2003 as the hospital’s pattern of disease, the researchers selected drugs to build a suitable drug list. The researchers determined 5 major selected criteria and marked them suitable to propose Drug list based on classifying group and subgroup of IV Essential Drug List. From the Drug List, formula for calculating needs and prediction cost of drug in 2004 was proposed. Sum up partially 1st quarter 2004, there was no differences between reality cost and predicted cost of drug

Investigating qualitative process of amphetamines in the narcotic sample gathered from narcotic drug cases in South cities and provinces by the color reactions, the thin layer chromatography or the gas chromatography. Result: most of amphetamines were under tablet form and a small number of them under powder or crystal form. Outside features was basic to test tablet and orientation for analysis. Methamphetamine content in S3, S5, S7, and S8 were relatively low (5.14-30.26mg/tablet). Methamphetamines content in S1 was high (64.46%). MDMA content in S2, S4, S6, S9, and S10 were relatively high (93.74-149.70mg/tablet). Application gas chromatography in quantification methamphetamine, MDMA that were agents commonly used in unlawful market in South provinces
