A score and more kinds of molluscan shells have been used as drugs in oriental medicine. The Korean Pharmacopoeia (K.P.) contains a monograph on oyster shell "Ostreae Testa" as an official drug. A huge deposit of the fossil shell Crassostrea gravitesta eoilensis has been recently excavated in the region of Wolsung, Kyong-Sang-Buk-Do. This study was conducted to determine the applicability of the fossil shell as a substiute for Ostreae Testa, K.P. The fossil shell not only met the K.P. requirements, but also exhibited an appropriate antacid activity. Amino acid survivals were also determined quantitatively with amino acid autoanalyzer.

Objectives: This study has been done to compare the Haematite's composition before and after using processing method and to clarify its quality and naming through the historical herbal books. Methods: I studied the Haematite and processed Haematite using physical and chemical methods which contain microscopic analysis, X-ray diffraction analysis, thermal analysis, XRF, ICP, etc, to compare the compositions and its characters. Results: Haematite is a metallic oxide(Hematite, $Fe_2O_3$). Haematite contains a main ingredients of crude Haematite Fe 40.336% - 62.174%, processed Haematite $50.499%{\sim}62.791%$(a theory value is 69.944% the korean pharmacopoeia wants >45%) and small ingredients, also. Conclusion: A radio-element contents of U, Th contain less than average contents of the lithosphere's U 1.8ppm, Th 7.2ppm.

This paper proposes to examine how herbal medicine studies developed amidst the historical changes, by studying the publications of herbal medicine books. For this reason, centering on the most eminent herbal medicine books of each period, the characteristic of the times shown by their publication and the development of herbal medicine were summarized. Also, traces of herbal medicine books among the eminent classics that were imported into our medicine and made a deep impact, and whether or not a Chosun edition was published were researched and introduced in order to show the influence it had on Korean Medical History.

The current definition of Arismatis Rhizoma is the tuberous root of Alisma orientale Juzepzuk in the Korean Pharmacopoeia, but there is still no marker compound. So it has difficulties in quality control. Therefore, in this study, we have established a method to analyze alisol B and alisol B acetate using HPLC as a marker compounds of Arismatis Rhizoma. As the result of the analysis, alisol B content was ranged from 0.02% to 0.50% and alisol B acetate content was ranged from 0.12% to 0.25% in 40 samples. The stability of alisol B and alisol B acetate was investigated during 24 months. As a result, alisol B acetate was significantly decreased. The marker compound of Arismatis Rhizoma is alisol B acetate and the content of 0.05% or more is suitable by applying the stability results.

A novel bioabsorbable suture material, poly(glycolide-caprolactone) (PGLCL) monofilament, was prepared by spinning of the PGLCL copolymer. The physical properties, strength retention, biocompatibility, and organism resolvability of the PGLCL monofilament were investigated. The results showed that the knot pull strength of the monofilament was higher than that stated in European Pharmacopoeia. The in vivo retention strength following implantation was 64%, 23%, 7%, and 0% after one, two, three, and four weeks, respectively. Mortality, clinical signs, validation, and sterility tests indicated that all items had passed. Organism resolvability tests showed that the PGLCL monofilament, as a suture, was absorbed within 91 days.

The clotting assay was replaced by the chromogenic substrate assay which is recommended by the European Pharmacopoeia (EP) and the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis based on the reliability convenience and simplicity of the chromogenic assay, A correlation study was carried out with a one-stage factor Ⅷ : C clotting assay and the performance of the chromogenic assay was evaluated using two test kits that fulfilled the requirements of EP for factor Ⅷ concentrates test. Although chromogenic assay has partly differences in measurement principle and standardization, this assay has a high correlation with clotting assay in various types of factor Ⅷ concentrates and factor Ⅷ standard. We conclude that the chromogenic assay for factor Ⅷ : C concentrates correlates well with the clotting assay and shows good analytical performance.

Near-infrared (NIR) system was used to determine rapidly and simply indomethacin in buffer solution for a dissolution test of tablets and capsules. Indomethacin standards were prepared ranging from 10 to 50 ppm using the mixture of phosphate buffer (pH 7.2) and water (1 : 4). The near-infrared (NIR) transmittance spectra of indomethacin standard solutions were collected by using a quartz cell in 1 mm and 2 mm pathlength. Partial least square regression (PLSR) was explored to develop calibration models over the spectral range 1100∼1700 nm. The model using 1 mm quartz cell was better than that using 2 mm quartz cell. The PLSR models developed gave standard error of prediction (SEP) of 0.858 ppm. In order to validate the developed calibration model, routine analysis was performed using another standard solutions. The NIR routine analysis showed good correlation with actual values. Standard error of prediction (SEP) is 1.414 ppm for 7 indomethacin samples in routine analysis and its error was permeable in the regulation of Korean Pharmacopoeia (VII). These results show the potential use of the real time monitoring for indomethacin during a dissolution test.

Zingiberis Rhizoma and Dioscoreae Rhizoma were processed according to chinese pharmacopoeia and literatures. The content of 6-gingerol in processed Zingiberis Rhizoma was significantly increased than that of unprocessed one. The content of allantoin in unprocessed Dioscoreae rhizoma through HPLC was $0.32{\pm}0.06%$ and after processing was not significantly decreased to $0.23{\pm}0.12%$.
