1.Preliminary study on application of some dosage methods of berberine chloride in raw material and berberin tablets
Pharmaceutical Journal 2005;0(1):22-24
Study on some methods used to quantify berberine chloride showed that the UV measuring and volumetric titration methods did not express only amount of berberine chloride itself. It is necessary to apply high- performance liquid chromatography (HPLC) to achieve the optimal conditions for better splitting, higher accuracy…in order to apply more widely in testing products commonly in market with many components combined to berberine chloride. To find out optimal methods, which are suitable with condition of present some pharmaceutical units, it is necessary to experiment continuously methods such as UV measuring and volumetric titration,… using HPLC method to compare.

2.Study on technical preparation of dexchlorpheniramine film coated tablets 6mg with sustained release
Pharmaceutical Journal 2000;291(7):15-18
Sustained release film coated tablets containing dexchlorpheniramine maleate were prepared in such a structure as two-third of drug were dispersed in Eudragit RS 100 to form insoluble matrix that gradually releases drug by diffusional mechanism, the rest was dispersed in the immediate release part. The core tablets were compressed by a wet granulation process and the film coated tablets by a routine film coating process with Eudragit E suspension. The formed coated tablets have suitable technical characteristics. The third formulation with Eudragit RS- drug ratio 2:1 has got the dissolution extent and the release rate in vitro similar to those of Polaramine 6mg repetabs. They also meet the requirements invitro release rate versus time for sustained release capsules containing Chlorpheniramine maleate by USP XXIII. Therefore, these film coated tablets with dexchlorpheniramine maleate may be candidates for a sustained release dosage form

Korean Journal of Urology 1990;31(6):869-873
Chronic prostatitis has various symptoms and many problems in management. Recently a lipidosterolic extract of Serenoa Repens, Permixon has been reported to reveal potential antiandrogenic and anti inflammatory activities on prostate. Then we used Permixon on chronic prostatitis and following results were obtained. Permixon is administered orally in dose of 160mg., b.i.d. for 60 days in 31 cases of chronic prostatitis in 1st group, Permixon 160mg, with Cipro-floxacin 500mg, b.i.d. in 35 cases in 2nd group and Placebo 2 tablets, b.i.d. in 30 cases in 3rd group. In 1st group 36 cases(77.4%) were improved, 29 cases(82.8%) in 2nd group and 7 cases (23.3 %) of 3rd group were improved. Permixon is an effective drug in chronic prostatitis and there was no changes in laboratory findings and negligible side effects were noticed

7.Preliminary study on application of fluoro - spectrometry for identification and dosage of riboflavine in the film - coated tablet Aphavita
Pharmaceutical Journal 2005;0(7):22-24
Preliminary application of fluorescerin spectrum to analyze riboflavine in Aphavita filmed tablet. Aphavita was a combination of vitamins B1, B6, B5, PP and adjuvants. Basing on the fluorescein property of ribofleavine, which depends on pH of tested media, the product was quantified. The qualitification showed the line criterion, the repeatation and the accuracy

10.Qualitative evaluation of some imported drugs before and after goods sending by Incotern 2000
Pharmaceutical Journal 2004;336(3):7-9
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 348 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
