The Japanese Good Laboratory Practice (GLP) Standard on Drugs was finalized as a guideline and implemented in April, 1983. This standard is intended to ensure the quality and integrity of the data from nonclinical toxicity studies submitted to the Ministry of Health and Welfare in support of applications for approval to manufacture or import new drugs or to be used in the reevaluation of previously approved drugs. The standard includes a guideline for organizational matters, personnel, facility, equipment, testing operation, documentation and conduct of studies. Principles and influences of implementation of Japanese GLP will be discussed briefly in comparison with foreign GLPs.

Good Laboratory Practice(GLP) is becoming more and more important in the research and development of Oriental Pharmacy(OP) and its globalization. If a OP product is to be registered as Over-the-Counter(OTC) drug and enter international markets, the safety and efficacy studies conducted according to GLP requirements is necessary. The article introduces the content of GLP requirements and the recent development of GLP. The safety and efficacy assessment for OP or herbal medicines under GLP are also covered. This paper also briefly describes the areas that should be covered by GLP regulation and the areas that do not need to follow GLP requirements.

The research and laboratory records management is the prerequisite for quality research. Quality research assurance system can work out on the sound basis of quality research records management. It is an important task that establishing a proper research and laboratory records system for obtaining quality of research according to the rapid growth of Research and Development area in Korea and the trend of electronic laboratory notebooks. The purpose of this study is to identify issues and find a direction for solutions related to the research and laboratory records management systems. For this after analysing previous studies and current status related to the research records management and GLP(Good Laboratory Practice) is benchmarked as a best practice for quality research, some suggestions for enhancement of research records management are given as a result.

Validation specifies and coordinates all relevant activities to ensure compliance with good laboratory practices (GLP) according to suitable international standards. This includes validation activities of past, present and future for the best possible actions to ensure the integrity of non-clinical laboratory data. Recently, validation has become increasingly important, not only in good manufacturing practice (GMP) institutions but also in GLP facilities. In accordance with the guideline for GLP regulations, all equipments used to generate, measure, or assess data should undergo validation to ensure that this equipment is of appropriate design and capacity and that it will consistently function as intended. Therefore, the implantation of validation processes is considered to be an essential step in a global institution. This review describes the procedures and documentations required for validation of GLP. It introduces basic elements such as the validation master plan, risk assessment, gap analysis, design qualification, installation qualification, operational qualification, performance qualification, calibration, traceability, and revalidation.

Safety pharmacology studies are conducted to investigated the potential undesirable pharmacodynamic effects of a substance on physiological functions in relation to exposure in the therapeutic range and above. In the International Conference on Harmonisation (ICH), the guideline 'S7A: Safety Pharmacology Studies for Human Pharmaceuticals' has been developed and reached Step 5 of the ICH process in 2001. Now the Korea Food and Drug Administration (KFDA) are going to transfer 'The Guideline for General Pharmacology' into 'The Guideline for Safety Pharmacology'. Safety pharmacology studies should be performed in compliance with Good Laboratory Practice (GLP). Thus, the present paper reviews the Japanese GLP guidelines for pharmaceuticals to help the conduct and inspection of safety pharmacology studies in compliance with GLP. We also reviewed the ICH guidelines 'S7B revised : The Nonclinical Evaluation of the Potential for Delayed Ventricular Repolarization (QT Interval Prolongation) by Human Pharmaceuticals' and 'E14 : The Clinical Evaluation of QT/QTc Interval Prolongation and Proarrhythmic Potential for Non-antiarrhythmic Drugs' to apply our drug approval systems.

A good material selection and high dental techniques shall be required in all procedure from waxing up to investing of wax patten in order to get a cast restoration with good adaptability. Generally, wax and investing material should not have any deformation property but they art not so perfact in practice. Therefore, as the one of methods to produce more perfact, less deformation property and excellent product, it is necessary to eliminate the problems which can cause a deformation in each procedure.

Background: Samul-tang (Si-Wu-Tang, SMT) is a traditional herbal formula, which has been widely used to treat various diseases such as menstrual irregularity, bleeding and leucorrhea. Although many studies have investigated the pharmacological properties of SMT, its toxicity information has not yet been fully elucidated. Methods: Five Sprague Dawley (SD) rats of each sex were given a single dose (5000 mg/kg) of SMT by gavage; control rats received the vehicle only. After the single administration, mortality, clinical signs, body weight changes and gross findings were monitored for 15 days in accordance with Good Laboratory Practice (GLP) principles. Results: In a single oral dose toxicity study, there was no adverse effect on mortality, clinical sign, body weight change or gross finding in any treatment group. Conclusions: The results indicate that SMT did not induce toxic effects at a dose level up to 5000 mg/kg in rats and its median lethal dose ($LD_{50}$) was considered to be over 5000 mg/kg/day body weight for both genders.

Purpose: Given that the critical nature of the microvascular anastomosis to what is often a long and difficult reconstructive operation, trainees need to have a high level of microsurgical competence before being allowed to perform microsurgery on patients. Some artificial substitutes and dead or live animal models have been used to improve manual dexterity under the operating microscope. Yet, most surgeons are not equipped with such models, so search for easy available and appropriate microsurgical practice model have been an issue. Umbilical artery, placental vessels and gastroepiploic arteries have been previously suggested as a microsurgical training model, which involves other surgical departments. The purpose of this article is to introduce that saphenous vein specimen obtained from varicose vein surgery is useful and has many advantages as training model for the practice of microvascular anastomosis. Methods: The conventional technique using perforation/inversion method with a metallic stripper is widely performed for varicose vein patients. The stripper is inserted through disconnected safeno-femoral junction and retrieved at the knee or the medial side of ankle. The length of saphenous vein specimens removed is about that of one's leg and inversed from inside out. Obtained saphenous vein specimens are re-inversed and cleansed with normal saline, to be readily available for microsurgical practice. Preserved in a squeezed wet saline gauze and refrigerated, frozen or glycerated specimens were investigated into their comparative quality for microsurgical practice. Results: Varicose vein surgery remains one of the common operations performed in the field of plastic surgery. Convenient informed consent regarding the vessel donation can be easily signed. The diameter of the obtained saphenous vein is as variable as 1.5 to 6 mm, which is already stripped, and is in sufficient length corresponding to that of patient's leg. Vessels specimens were available for microsurgical practice within 1 week period when preserved with squeezed wet saline gauze, and the preservation period could be extended monthly by freezing it. Conclusion: Saphenous vein obtained from varicose vein patients provide with variable size of vessel lumen with sufficient length. The practice can be cost effective and does not require microsurgical laboratory. Additionally there is no need of involving other surgical departments in acquiring vessel specimens. Furthermore, simple preservation method of refrigerating for a week or freezing with squeezed wet saline gauze for a month period, allow the saphenous vein obtained after varicose vein surgery as an excellent model for the microsurgical practice.
