Donguibogam, Korea's cultural heritage and traditional Oriental medicine book listed in the World Heritage three years ago, is indeed great in its importance and value. Korea's posterity has sought treatment methods through the medical book and their researches on that book have continued. However, it is rare to make the concrete analysis on the medicines for prescriptions recorded in the book. In this study, we reviewed "Ears" in the Section "Bodily Appearance" among the five chapters of Donguibogam, and analyzed the 55 types of prescriptions for ear diseases, the medical characteristics, tastes, prime classification of medical herbs, and acupunctural effects, and the dosage forms depending on prescriptions. For insect-entering ear diseases and 20 kinds of a single-medicine prescription also, the treatments are presented in the book, but we presented the texts only and excluded them in the analysis. We also excluded overlapping prescriptions and adding and reducing prescriptions of the 55 prescriptions, and thus classified the left 42 proscriptions by dosage form. As a result: 1. With respect to medical characteristics, the medicine with warm characteristics reached 9 types(40.9%), the highest rate, followed by the medicine with cold characteristics 8 types (36.4%). 2. Concerning medical tastes, the medicine with bitter taste included 12 types (54.5%), the medicine with sour taste 10 types (45.5%), and the medicine with sweet taste 7 types (31.8%). It was unusual that of the 22 medicines used for multipurpose, no medicine with the taste was found. 3. For the acupunctural effects, the medicine with acupuncture effects for spleen medirian reached 12 types in total (54.5%). On the contrary, the medicine with the effects for pericardium meridian reached only one (4.5%) among the total of 22 medicines. 4. In the dosage form of 42 prescriptions, powder medicine was 15 types (35.7%), and decoction medicine was 14 (33.3%). Powder, dedoction, and pill medicines accounted for 90.4% of the total medicine type. It was found that in particular, for ear diseases powder medicine was used more frequently than decoction medicine.

Bioequivalence test of $Asthcontin^{\circledR}$ tablet, a commercial slow-release theophylline (TP) dosage form, was performed using $Slo-bid^{\circledR}$ capsule as the reference. Since it has been confirmed that the saliva concentration of TP is closely correlated with the plasma concentration in man, the area under the saliva concentration-time curve was used as a bioavailability parameter. The statistical analysis showed that the two dosage forms are equivalent in bioavailability estimating from the saliva concentration. The results supported that the use of soliva as a test sample provides simple and easy techniques for bioequivalence tests of TP-containing dosage forms.

Ginsenf Radix (Panax ginseng C. A. Meyer) has been traditionally used as a herbal medicine for many therapeutic or prophylactic purposes in the oriental countries such as Korea, Japan and China for at least two thousand years and also extensively studied in the modern scientific field of chemistry, biochemistry and pharmacology. The herb is now also indicated for use as tonic or a prophylactic and restorative agent for enhancement of mental and physical capacities, in case of weahess exhaustion tiredness loss of concentration, impotence, cold limbs, during illiness anuor convalescence. Ginseng is commonly used in the form of detections, extract and powderl and ginseng products, in the form of capsules tablets and drinks. And also ginseng radix has been widely traditionally prescribed as an important comuonents of manny Chinese prescriptions or alone in various diseases and for health with its different dosages. Nowadays since rinsenf can be generally classified into food or medicine in many nations, it is very difficult to give any exact desnition on the dosage, which may be of particular importance in clinical applications. In addition, the establishment of the reasonable dosage is currently of great significance to meet the demand for such wide applications. Accordingly in this review paper we summarized the dosage of ginseng on the basis of oriental medical books oriental and western pharmacopeias and modern scientific clinical data. The recent survey demonstrated that the averare dosare of finsenf is considered to be three to four grams per day unless prescribed apart, while one to two grams per day in western countries from the western viewpoint of classification of ginseng as a medicine, surrorted by the dosage of not more than one gram per day in most clinical studies. For that reason, it seems likely that the dosage in western countries is ascribed to the safety of ginseng considering side or unwanted effects. Consequently whether the differences of dosage between oriental and western countries depend on dietary habits and races should be closely investigated. Besides, further studies on the pharmacokinetics and bioavailability of ginseng components in clinical trials need to be done to decide optimum dosage of ginseng.

Nelumbo nucifera root(NNR) is used to clear summerheat(暑熱), bear Yang(陽) upwards and stop bleeding as mentioned in traditional Korean medicine. Also, it has been known that NNR is effective for lowering blood pressure and hyperlipidemia. The rhizome is considered to be nutritive, demulcent, diuretic and cholagogue and is used to treat piles, dyspepsia and diarrhea. An increasingly growing market for nutraceuticals and functional foods has triggered the study on natural sources for nutraceuticals, health foods and functional foods. But rhizome was inconvenient to formulate liquid dosage form(extract) by way of hot water because of its limited storage. Also the majority of the consumers have a complaint against the dosage. The purpose of this study was to develop the functional materials from NNR without side effects. We formulated the solid dosage form viz tablet and granule from the lotus root. Sensory evaluation was performed in terms of smell, taste, color and overall of lotus root and all colored forms(brown, dark brown, light green and yellow) of tablet and granule to evaluate the acceptability of the formulated tablets and granules. In sensory evaluation, among the formulated tablets and granules, light green granules obtained best score overall and yellow tablets showed the overall improved acceptability. In conclusion, lotus rhizome could be recommended as functional food. Further studies to clarify bioactive functions of Nelumbo nucifera in experimental animal model on atopic dermatitis are in progress.

The aim of this study was to prepare and evaluate tablets containing liquid choline alphoscerate, which is capable of being formulated as a solid dosage form by the adsorption of magnesium aluminum silicate. The tablets were prepared with various absorbent to choine alphoscerate ratios. The physical properties and the dissolution rate were investigated. Considering the tabletting and dissolution rate, the formula scontaining 50-75% absorbent were adequate in the tested formulations. The 62.5% absorbent formula showed superior results with the tests of hardness, friability, disintegration time, and the ratio of dissolution area under the curve. Overall, magnesium aluminum silicate can be an alternative additive to a liquid drug.

An automated, simple, and reliable method was developed for determining in vitro drug release rate from transdermal delivery dosage forms. The patch is held in position in the heating block by sandwiching it between the middle plate and the bottom plate of diffusion cell. The dissolution profile of the commercially available transdermal scopolamine patch was determined over a 72-h period, and the results were compared with those obtained with other methods; paddle-over-disk method, reciprocating method, and diffusion cell method. It was demonstrated that the flow-through method is equivalent in terms of release rate profile and accumulated released drug amount over the lifetime of the dosage form tested. Also this method is simple, reliable and reproducible. Therefore, this technique can be used in a quality control for assuring product uniformity.
