1.Synthesis, structure and biological effects of some compounds of 2-mecaptobenzothiazole
Pharmaceutical Journal 1998;272(12):14-16
Nine compounds derivated from 2-mercaptobezothiazole were synthesized. Their structure have been identified by MS-, IR-, and UV- spectroscopy. Antimicrobial activities of some compounds have been tested. Hydrazide BT6 and substituted hydrazides BT7, BT8, BT9 were found to have significant inhibitory activity on P. aeruginosa, S. aureus, Asp. niger and F. oxysporum at concentration 50mcg/ml.

Realtime xCELLigence analysis (RTCA) is a new cell detection technology to continuously monitor, record and analyze a variety of information generated by cell activity. In drug research, it plays an important role in assessing myocardial toxicity and cell biological activity. Here, we first introduce the underlying mechanisms and characteristics of RTCA. Then we review the applications of RTCA in the research of myocardial toxicity and cell biological activity, to provides the fundamental baseline for understanding and exploiting RTCA. With the real-time, unlabeled, non-invasive, high throughput, and high accuracy features, RTCA not only promotes drug research and development, but also has a broad and good application prospect in other fields.

4.Quality monitoring of artesunate 50mg tablets produced in Vietnam
Journal of Malaria and parasite diseases Control 2003;0(6):23-28
Quality of the locally produced artesunate 50mg tablets provided by the National Malaria Control program to five provinces of Cao Bang, Bac Kan, Ha Tinh and Ninh Thuan was monitored in a survey from June 2001 to December 2004 that was conformed with the expiry date of the drug. The drug had also been previously found to meet the quality criteria of manufacturer and pharmacopoeia. Analysis of samples collected from five provinces showed a remaining stable quality of mass equability, disintegration, hardness and solubility as permitted limits. The artesunate concentration was found to be 90-100% and 95-105% according to pharmaceutical classes and manufacturer criteria, respectively

5.Contribution to study on selecting a drug list and estimating drug demand in Khanh Hoa Rehabilitation Nursing Hospital
Journal Ho Chi Minh Medical 2005;9(3):170-175
To establish an appropriate hospital drug list, the local disease prevalence and the revision of drug treatment in Khanh Hoa Rehabilitation Nursing Hospital, a survey and statistics were taken in 9 years (1995-2003). The disease categories observed in the hospital were contained in 19 chapters of The International Classification of Diseases and Related Health Problems - 10th revision (ICD10). Three chapters associated with high prevalence are chapter VI (Diseases of the nervous system), chapter IX (Diseases of the circulation system), and chapter XIII (Diseases of the musculoskeletal system and connective tissue). Based on the local disease prevalence observed in the hospital, treatment guidelines, management capability and payment ability of patients, the Multi-Attribute Decision Analysis Method (MADAM) was applied to list available drugs used in Khanh Hoa Rehabilitation Nursing Hospital. Five decision evaluation criteria including efficacy, safety, ease of use, cost of drug and origin of drug were weighted and scored for the choice of drugs. The obtained result was a drug list which almost uses and promotes the 4th Essential Drug Concept

7.Analysis of drugs with several components by UV-VIS MCA spectrophotometric technique - An application of informative industry in drug control
Pharmaceutical Journal 2001;298(2):17-21
Some algorithms used in UV-Vis MCA spectrophotometry technique and some recent statistical approaches to the Advanced MCA technique were described. A number of pharmaceutical formulas containing 2-4 ingredients has been analyzed successfully using MCA technique. Basing on the basic algorithm of MCA and its statistical approaches, an applicable software for data processing had been established (running in Windows (environment - IBM compatible computer). This enables to use MCA technique for conventional spectrophotometers.
