  • Tissue engineering has arisen to address the extreme shortage of tissues and organs for transplantation and repair. One of the most successful techniques has been the seeding and culturing cells on three-dimensional biodegradable scaffolds in vitro followed by implantaion in vivo. We used PLA and PLGA as biodegradable polymers and rabbit chondrocytes were isolated and applied to PLA and PLGA to make artificial cartilage. To evaluate the biocompatibility and biological safety of polymers, in vitro cytotoxicity and in vivo animal tests were investigated. (omitted)

  • The purpose of the present studies was to investigate the effects of subchronic paternal treatment of cyclophosphamide (CP) and acrolein on male fertility and early embryonic development. Two approaches were pursued. The first was to perform in vivo test for observing the adverse effects of CP and acrolein on the function og male reproductive system and pregnancy outcome.(omitted)

  • Drug dissolution test has been used for the purpose of both quality control of solid oral dosage forms and predicting in vivo drug release profiles. In this study, the dissolution profiles of buflomedil hydrochloride tablets and ticlopidine hydrochloride tablets were investigated according to the "Guidelines on Specifications of Dissolution tests for Oral dosage forms" of Korean Pharmacopoeia (KP). The analytical method using HPLC was validated. The validation was performed in terms of specificity, linearity, accuracy, precision and limit of quantitation.

  • To secure the good quality of pharmaceutical products, dissolution specifications for Octylonium bromide tablets and Pinaverium bromide tablets are needed to be established, which are enrolled in KPC (Korea Pharmaceutical Codex) with having no appropriate specifications. For establishing dissolution specifications, a number of experiments based on the "Guideline of Dissolution Testing for Solide Oral Dosage Forms" were performed. The results of this study will be used for revising KPC and it is expected to contribute to the incessant production of quality ensured drugs.

  • The aim of publishing the Korean Pharmaceutical Codex is to update and set specification of essential drugs for humane health. In accordance with speedy development of new drugs and improvement of science and technology, the need of revision of drug specification through the ICH guidelines and discussions between regulatory agency and pharmaceutical industry for the quality assurance of safer and efficient drugs is getting higher. The first edition of Korean Pharmaceutical Codex was published in 1983. Now, the third revision of the Codex is prepared because of the revision of domestic and foreign Pharmacopeias, changes of drug control environment, improvement of science and technology and so on. The aim of 3th edition is to improve the quality of essential drugs through the setting of the required specifications and discussions between the regulatory agency and pharmaceutical industry.

  • The "Guidance Document for Bioequivalence Study" was revised for adding to bioequivalence studies of controlled-release products after meal(Korea Food & Drug Administration Notification #2008-22, 2008.5.7). The bioequivalence study design for controlled-release products is $2{\times}2$ crossover under fast and fed condition in respect. For studies of controlled-release products under fed study, the same high-fat diet should be taken within 20 minutes in at least a 10-hour fasting state. The drug products should be administered 30 minutes after the meal started. A high-fat(more than 35 percent of total caloric content of the meal) and high-calorie(over 900 calories) meal is recommended as a test meal for fed BE studies.
