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.

Artesunat at doses of 50 mg/kg the first day and 25 mg/kg per day for four following days had no effect to the birth progress of P, F1 and F2. Concretely: No coffuse birth: ratio of conjugation, conception, early died feotus and late died feotus among P, F1 and F2 were similar, and were not higher than control group. No innate defects in born mice from P, F1 and F2. Quantity and weight of mice were in normal, and were not different with the control group

The researchers built targets and way to handle skin and built quantitative method notroglucerin by high-performance liquid chromatography (HPLC) and quantitative method total nitroglucerin content in sticking-plaster Discotrin 36mg with area of 13,3cm2. The study was carried out in 6 samples and average with RSD = 0,47%, from there find out exactly nitroglycerin level on 1cm2 to evaluate permeation of nitroglycerin through skin in different temperatures ( 41oC, 37oC, 25oC). The result showed that the higher temperature, the more Nitroglycerin is permeated. The permeation of nitroglycerin through skin is defferent in each animal

The goal: Pellet was introduced into sustained release product containing indometacin to promote the advantage of this drug form. The material: Indometacin (China), avicel pH 101 (Taiwan), lactose (Holland), polyvinylpyrolidon (Holland), hydroxypropyl methylcellulose (England)… The method: Pellet indometacin was prepared by layering method. The result: the optimal formulary to prepare sustained release pellet indometacin using layering method was selected. Coated pellet may be filled into the capsules shell or compressed into tablet having sustained release effect by oral (up to 12h)

Gel erythromycin 4% (type 10g) was compounded in 3 lot at Pharmacy Department of the School of Medicine and Pharmacy Can Tho. The method: Carring out test on 3 lot of product aim to build the criteria, each lot was tested minimum 3 times for criteria including apperance, vicosity, pH, particulate matter, weight uniformity, identification and assay. The result: The draft of test criteria for gel erythromycin was buitt to contribute introduce this subject into phamacopoeia. Additionaly, quantitative determination of erythromycin in the gel product was carried out by microbiological method

Providing good quality drugs is the major duty of the Pharmaceutical Branch. However, in the market, there have still been drugs having qualities which are worse than they were registered in The Drug Administration. This causes a bad effect not only to the consumers but also to the economy. Moreover, the important thing is that it can create a bad prestige for the Vietnamese Pharmacy. And of course, it is also a big barrier for Vietnamese products in circulating in the international market. The investigation wants to show a comprehensive picture of the drug quality’s situation in The Southern Area of Vietnam from 1997 to May 2000
