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.

Compounding pellet chlorpheniramin TDKT and builing its formulary from pellet were studied. The result: the optimal formule of memberance prolonging release of chlorpheniramin from pellet was selected. This memberance could quicktly release a part of primary subtance in order to immediately solve alergic symptoms. The rest release constantly prolong in 8 hours

From 2000-2004, the authors examined medicament were imported and delivered in Lao Cai province to investigate quality of them. Results showed that: the rate of bad quality medicament was 4.9%, among which the rate of injection drugs was higher than tablet drugs. The domestic medicament had a bad quality was higher than imported medicament (5.3% vs. 3.2%, respectively). The bad quality rates of vitamins and tonic drugs were the highest (6.7%), antibiotics 2.6%. This rate in the mountain and rural areas was higher than that in the city.

Study on 41 pharmaceutical companies in Hanoi city from March 1999 to February 2000. The results: there was an average of 46 pharmaceutical companies of sixteen countries bought the biding documents and about 43% of those companies submitted the bid documents. At each International Competitive Bids, the average of prices of pharmaceutical drugs were correlative with that announced by UNICEF, however, there was still a case of the mean prices of pharmaceutical drugs were higher than that announced by UNICEF. The prices of pharmaceutical drugs were considered lowest, lower than the average of prices of similar products, which were imported into the Vietnam market and announced by UNICEF

Antimalarial drug samples were collected from different parts of the country for quality investigation in 2004. A total of 129 samples of different batches were collected at three rounds and cross-checked at local, central level and abroad. At the round one, three out of 49 collected samples were found substandard. One of 40 samples of the second round was determined counterfeit (2.5%). The re-analysis of 51 samples at NIDQC revealed two from the first round were substandard and one from the second round was counterfeit

Study on 2 drugs of combined components: The drug number 1: combined tablets of Ethambutol/Isoniazide 400/150mg; The drug number 2: combined tablets of Rifampicine/Isoniazide 150/100mg and Pyrazinamide 500mg. These drugs delivered from India to Vietnam by the airway or shipment during April 2001 to September 2003. The results showed that: delivering time was approximately 10 days in airway and estimated time of 32 days in shipment. The time for issuing Vinacontrol's cerfiticate on drug quality was approximately 348 days, the time for issuing certificate on drug quality was longer than delivering time both the airway and the shipment. The results of testing drug quality before and after delivering pharmaceutical drugs from India to Vietnam found that testing indicators excepted assays were as same in certificate of manufacturer, SGS International and Vinacontrol and assay of imported drugs was in rank of registered standards

The reality, some results and shortcomings of privatization process of state owned pharmacies were evaluated at period 1999-2003. The result: privatizating state owned pharmacies is relatively good, the amount of privatizated state owned pharmacies increase continously in past years. However, although there were 54,1% of provinces and cities implementing privatization but mainly that are enterprises belong to 2 regions of The Red river delta and South- East Viet Nam. This showed that the privatization process of regions isn’t equal. According to the plan, in 1998 there had been 7 units carrying out privatization but to the end of the 2000, there was only 1 first unit conversing successtly. That is the branch of Hai Phong 1 Health company changing into HaiPhong Health trade privatization company.
