To strengthen the quality control of aquatic drugs, we compared the internal and external(EU, USA and Japan) aquatic drug classification systems and proposed a new aquatic drug classification system. Aquatic drugs are classified on the basis of their functional the functional characteristics or safety management degree of aquatic drugs. We suggested that the aquatic drugs can be categorized into 7 levels according to their functional characteristics and classified into 3 levels according to the safety management degree of aquatic drugs.

Objective : To investigate the current status of prescription drugs in Oriental medical institutes and to draw up a future plan for the revitalization of Oriental medical health insurance, this survey has been performed. Method : The survey has been made with 321 doctors working at Oriental medical institutes in Daegu and Kyungbuk areas for a period of 3 month from June 1, 2010 until September 1, 2010. Result : 1. When it comes to the current status of the use of herbal drugs in Oriental Health insurance, most of doctors surveyed prescribe insurance drugs, and they prescribe insurance drugs to patients, who are less than 20% of total patients visiting their clinics. 2. The awareness of Herbal Health Care Drugs is investigated. When it comes to the understanding of the difference between insurance drugs(powder type drugs) and granular type drugs, doctors admit that they differ only in one aspect, whether or not their being covered by health insurance. Based on the survey results on the understanding of insurance coverage of granular type drugs, doctors, even though they long for granular type drugs to be accepted as insurance drugs, are worrying whether the number of outpatients might dwindle due to increased insurance co-payments. They also point out that the biggest obstacles in the expansion of the granular type drugs as insurance drugs are the lack of understanding of the government and the objection of the Health Insurance Review and Assesment service (HIRA) for fear of increased insurance claims. 3. Upon investigation on Oriental medicine doctors' understandings of herbal pharmaceutical industry, it is found that doctors' responses on pharmaceutical industry are not all positive ones('new product development and neglect of R&D infrastructure' and 'smallness of industry'). When it is investigated what area needs the greatest improvement in herbal pharmaceutical industry, 'securing sufficient capital, good manufacturing, and strengthening quality control', is the highest. 4. When it is asked what are the most needed in order to improve herbal health insurance medicine, responses such as 'the increase in the accessibility to and the utilization of Oriental medical clinics through the diversification of the means of prescriptions', 'the improvement of insurance benefits(cap adjustments)', 'increase the proportion of high quality medicinal plants', 'the ceiling of co-payments(deductible) at 20,000 won or more', 'expansion of the choices of formulations', 'formulational expansions of tablets and pills', and finally 'admittance and expansion of granular type drug as insurance drug' are the highest. 5. Upon investigating the general characteristics of the current status of the usage of Oriental health care herbal drugs, the followings are observed. First, the frequency of use of health insurance drugs by the doctors who use health insurance with general characteristics shows similar differences in case of total monthly sales amount (p<0.001), average number of daily patients (p<0.05). Secondly, as to the willingness of the expanded usage of insurance drugs, similar differences are observed in case of total monthly sales amount (p<0.05). 6. Upon investigating the general characteristics of the perception of Herbal health care drugs, the followings are observed. First, inspecting general characteristics and insurance claims due to increased co-payments(deductible amount) reveals similar differences in case of working period (p<0.01) and in case of total monthly sales amount (p <0.01). Secondly, inspecting general characteristics and the obstacles that hinder granular type drugs from being accepted as health care insurance drugs shows similar differences in case of working period (p<0.05). 7. Upon investigating the general characteristics of the understanding of Oriental Herbal pharmaceutical companies, the followings are observed. First, opinions on the general characteristics of pharmaceutical companies, when examined with variance analysis, shows similar differences in case of total monthly sales amount (p<0.05). Secondly, when opinions are examined on general characteristics and the problems of herbal pharmaceutical companies, similar differences are found in case of working period (p<0.01) and in case of total monthly sales amount (p<0.001). Lastly, opinions on the general characteristics and reforms of pharmaceutical companies, similar differences are observed in case of working period (p<0.001). 8. Upon investigating the general characteristics of the improvement of insurance Herbal drugs, the followings are observed. First, regarding general characteristics and insurance benefits, similar differences are observed in case of working period (p<0.05), in case of total monthly sales amount (p<0.05), and in case of average number of daily patients (p<0.01). Secondly, opinions on the general characteristics and the needs for the improvement of Herbal insurance drugs are examined in 5 different aspects, which are the approval of granular type drugs as insurance drugs, the expanded practices of the number of prescription insurance drugs, the needs of a variety of formulations, the needs of TFT of which numbers of Oriental medical doctors are members for the revision of the existing system, and the needs of adjusting the current ceiling of the fixed amount and the fixed rate. When processed by the analysis of variance, the results show similar differences in case of average number of daily patients (p<0.01). Conclusion : From the results of this study the first measures to take are, to reform overall insurance benefit system, including insurance co-payment system(fixed rate cap adjustment), to expand the number of the herbal drugs to be prescribed matching with insurance benefit accordingly, and to revitalize herbal medicine insurance system through the change of various formulations. In addition, it is recommended to improve the effectiveness of herbal medicine by making plans to enhance the efficacy of herbal medicine and by enabling small pharmaceutical companies to outgrow themselves.

A new physico-chemical method for identifying botanical drugs was investigated. Fifty drugs were chosen from the presently exported botanical drugs and were classified into 12 groups chemotaxonomically. Various extract(either, 50% ethanol and water) of each group were developed with same solvent system by using chromatographic method(TLC) and observed a characteristic pattern of each drugs. This method, therefore, can be applicable to identify each botanical drug out of the combined phyto-preparations.

Many types of drugs affect functions of tile gastrointestinal tract. Investigators may be interested in discovery or pharmacological characterization of drugs as therapeutic agents intended for treatment of gastrointestinal disorders or in identification of gastrointestinal side effects of drugs intended for non-gastrointestinal indications. Examples of drug categories often associated with significant gastrointestinal side effects include cardiovascular drugs, antibiotics (erythromycin in particular), anti-inflammatory drugs, antiemetics, analgesics (especially opiates), antihistamines, antidepressants, and antipsychotics. Whether tile objective is development of gastrointestinal therapeutic agents or evaluation of gastrointestinal side effects, appropriate laboratory models for experimentation are essential.

In order to investigate the side-effects of crude drugs, twenty drugs have been tested for the teratogenic effect in rats. Among seven drugs contained alkaloid as their ingredients, no one showed teratogenic effect, but Veratri rhizoma showed embryo-toxic as revealed by severe retardation in growth of the fetuses. The other thirteen drugs which have been used freguently in oriental medicines exhibited no teratogenic effect. Cyclophosphamide used as a reference compound showed severe malformation and retardation in the growth of rat fetuses. These findings suggest that the drug extracts adopted for the study might have no teratogenic effect in the rats.

The odor theory (기미론) has been defined as the Nature (기) and the Taste(미) of traditional herbal medicine to find the logic in treatment of various diseases by them. There is a strong possibility these Na1ures of the drug can be categorized according to yin (음) and yang (음). There is a neutral Nature which does not fit into one of these four categories. To understand the Natures of traditional herbal drugs in modern scientific approaches, changes in rectal temperature of rats have been measured at 0,30, 60, 90 min after a 10 g/Kg oral administration each of 34 different drugs. Following the classification of the four Natures of drugs, only the temperatures of warm group at 30, 60, and 90 min were elevated significantly from the control and the rest groups. Following a modified classification of 3 groups such as cold and cool, warm and hot, and neutral Nature, changes in temperatures after administration of Hot and Warm drugs were also increased significantly from the control (P<0.01). Thus, the measurement of rectal temperature can be a tool to define the Nature (기) of traditional herbal drugs, but the modified classification is another way to do.

Veterinary drugs are widely used to protect production-related diseases and promote the growth of farmed fish. The use of large amounts of veterinary drugs may have potential risk and cause adverse effects on both humans and the environment. In this study, we developed risk-based ranking based on a scoring system to be applied in the national residue program. In this approach, the following three factors of veterinary drugs that may occur as residues in fishery products were considered: potency (acceptable daily intake), usage (number of dose and withdrawal period), and residue occurrence. The overall ranking score was calculated using the following equation: potency × usage (sum of the number of sales and withdrawal period) × residue occurrence. The veterinary drugs that were assigned high score by applying this approach were enrofloxacin, amoxicillin, oxolinic acid, erythromycin, and trimethoprim. The risk-based approach for monitoring veterinary drugs can provide a reliable inspection priority in fishery products. The developed ranking system can be applied in web-based systems and residuemonitoring programs and to ensure safe management of fishery products in Korea.

Avian coccidiosis is a very important disease of poultry industry. In recent years, many researchers studied for the immunology of avian coccidiosis. Coccidial vaccines have been used at some poultry farms in many countries. In order to evaluate the anticoccidial effects of coccidial vaccine to chicken treated with anticoccidial drugs, 4 week-old chicken were administered anticoccidial drugs and challenged with avian coccidia at 2 weeks after vaccination of coccidia. The body weight gains, lesion scores, oocyst indices and anticoccidial indices of chicken were investigated at the time of vaccination, challenge and necropsy. The body weight gains and feed conversion rates of groups immunized with coccidial vaccine and treated with anticoccidial drugs were moderately higher and lower than those of groups treated with anticoccidial drugs, respectively. The lesion score and oocyst indices of all groups immunized with coccidial vaccine and/or treated with anticoccidial drugs were milder than those of infected control groups. The anticoccidial indices of groups immunized with coccidial vaccine and treated with anticoccidial drugs were moderately higher and lower than those of groups. treated with anticoccidial drugs. But all of the investigated items were not statistically significant.

In the result of investigating the drugs for replenishing Qi in many herbal books, we could get consistent relation in their immunopharmacologic effects as follows: 1. The effects of drugs for replenishing Qi was shown in the Shen Nong's Herbal, but its classification was natural such as trees and plants, insects and beasts, fruits, vegetables, and we think that trial about classification of drugs for replenishing Qi was accomplished in the ben-cao-jiu-zhen(本草求眞). 2. Main drugs for replenishing Qi was Gingseng Radix, Codonopsis pilosulae Radix, Astragali Radix, Atractylodis macrocephalae Rhizoma, Dioscoreae Rhizoma, Glycyrrhizae Radix. 3. Drugs for replenishing Qi commonly contain polysaccharides as much, and it was thought that they have also immunopharmacolologic effects by means of activating T and B cells, secreting cytokines, making lymphocytes, activating NK cells, increasing abilities of voracity and generating antibodies. 4. Drugs for replenishing Qi mainly replenish lung-Qi and Wei-Qi so that they have also effects of activating T and B cells, secreting cytokines, making lymphocytes, activating NK cells, increasing abilities of voracity and generating antibodies. 5. Drugs for replenishing Qi modulate content of cAMP and inhibit Na(+)-K(+) ATPase, so that they have effects of treating indistinctive pulse from Qi deficiency by means of inhibition delivery of chemical substances, activating lymphocytes. promoting contraction of myocardium.
