The mutagenic activities of the pyrolyzates (300, 600, 750 and 85$0^{\circ}C$ ) of extracts from three saponeous expectorants (Platicodi Radix, Polygalae Radix and Asiasari Radix) and two nonalkaloidal antitussives (Lirionis Tuber and Codonopsis lanceolata Radix), medicinal plants, were studied in the Ames Salmonella/microsomes test system. The pyrolysates of Codonopsis lanceolata Radix and Asiasari Radix extracts at 85$0^{\circ}C$ were slightly mutagenic to tester strain TA98( frame shift ) and TA100(base-pair substitution) of Salmonella typhimurium, and the mutagens in these pyrolyzates required the metabolic activation by a liver microsomal fraction However, the extracts and pyrolyzates of all medicinal plants tasted except the above two results dud not show the significant increase in revertant colonies.

This study was aimed; firstly to observe various clinical symptomatology with reiation to the number of Ancylostoma duodenale larvae orally given to the human beings, secondly to evaluate the effects of some drugs like steroid hormones, antihistaminic3 and antitussives, and, thirdly to study the influences of some iron compounds in prevention and treatment of anemia of such origin. Ten healthy volunteers free from the previous history of hookworm infection were divided into 4 groups, to whom various numbers of actively moving filariform Ancylostoma duodenale larvae were orally given; 500 to 4 cases, 250 to 3 cases and 100 to 3 cases. Following were the results: 1. Clinical symptomatology 1. The most frequently encountered symptoms and signs were general malaise, cough and hoar seness. The tracheal itching and pain low back pain, arthralgia, sputum and salivation, acid belching, loss of appetite, abdominal pain and vomiting were also noted. 2. If the larger number of the larvae was given, the clinical symtomatology was more severe. 3. Prednisolone medication caused some improvement of such symptomatology, while the antihistaminics and antitussives like codeine or ephedrine were ineffective. 4. In volunteers whose nutritional conditions were rather poor appeared to show more severe symptomatology. 2. Effects of iron compounds 1. The oral administration of ferrous fumarate induced a slight increase of serum iron levels in the initial stage of the infection, then a decrease from $15{\sim}20$ days later and a recovery after 2 months. 2. The intravenous administration of saccharated ferric oxide induced a steady upkeep of the serum iron levels. 3. The hemoglobin contents also showed the upkeeps after either the oral or intravenous administration of the iron compounds. 4. The iron compounds, therefore, are considered to have the preventive as well as the therapeutic effects on hookworm anemia, which may strongly suggest that hookworm anemia is essentially the iron deficiency type. 3. Hematological changes 1. The severity of hookworm anemia generally correlated with the number of larvae given. 2. The moderate leucocytosis was observed in all cases regardless of the number of larvae given, which reached to a peak in $25{\sim}35$ days. 3. Eosinophilia was observed in all cases, but was more severe in cases given larger number of larvae, which was slightly less evident after the medication of prednisolone. 4. Red cell survival time The red cell survival time determined by $^{51}Cr$ was generally in the normal ranges except for the severe anemia patients.

Citrus unshiu Marc., a family of Rutaceae, has been used as antitussives, antiemetics, expectorants, spasmolytics, stomachics and digestants in oriental medicine. But there is few reports on the pharmacological effects of Citrus unshiu pericarpium. Present experiment was performed to observe the effects of the water extract of Citrus unshiu on isolated auricle and intestine in rabbits and blood pressure in rats and also to study on the active component on the cardiovascular system by means of thin layer chlomatography and spectrophotometer. 1. The water extract showed positive inotropic and positive chronotropic effect in the concentration of $1{\times}10^{-4}g/ml$, $5{\times}10^{-4}g/ml$, and $1{\times}10^{-3}g/ml$. 2. The motility of isolated rabbit intestine was significantly depressed by the water extract. 3. The blood pressure was markedly increased by the water extract. 4. The blood vessel of rabbit ear was constricted by perfusion of the ether extract. 5. The purified alkaloid of Citri pericarpium by ion exchange resin showed the same Rf value with l-synephrine on thin layer chromatography. 6. The purified alkaloid of Citri pericarpium by thin layer chromatography showed the same absorption curve with l-synephrine in the ultraviolet scanning.

The leaf of Phyllostachys bambusoides S. et Z. (Gramineae) has been used in traditional herbal medicine as a antipyretics, antitussives and antidiuretcs, etc, in Korea, China and Japan. In order to investigate the effects on antilipoperoxidation and liver protective effect, the leaf of Phyllostachys bambusoides S. et Z. was extracted by water and then fractionated with butanol. The water extract and BuOH soluble fraction strongly exhibited antilipoperoxidatant effect in rat liver homogenate intoxicated with $CCl_4$. The BuOH fraction significantly suppressed the increases of s-GOT, s-GPT and s-LDH activities in injuried rats induced by $CCl_4$. And the BuOH fraction inhibited significantly the decrease of the body weight and showed the antilipoperoxidatant effect in liver and kidney in $CCl_4$ intoxicated rats.

Asthma is a chronic inflammatory disease of the airway and the prevalence rate is increasing. As the burden of asthma to the society is significant due to the increasing hospital admissions and emergency visits, National Heart, Lung and Blood Institute (NHLBI, USA) and World Health Organization (WHO) have developed comprehensive guidelines to help clinicians and patients make appropriate decisions about asthma care. The aim of study was to analyze the pattern of asthma prescriptions based on the national asthma guidelines for the patients visiting primary health care providers. Prescription data for asthma were obtained from the Korean National Health Insurance claims database of January 2002. Ten percent of the primary health care providers were sampled based on their specialty areas, and 20％ of the claim cases were randomly chosen. Study results showed that prescription rate for oral beta-2 agonists was 44.3％, and that for oral theophylline was 46.9％. Oral steroids were prescribed for the 28.2％ of the claims. Utilization of inhalers was low for both bronchodilators (20.3％, beta-2 agonists inhalers), and steroids (8.4％ steroids inhalers). Bronchodilators were more preferred to the longterm anti-inflammatory controllers among the primary health care providers. Prescription rate for antibiotics was 46.0％ for asthmatic patients. Also gastrointestinal drugs were prescribed for 59.0％, antitussives 65.3％, antihistamines 25.3％ and analgesics 29.4％, respectively. This study presented that the prescribing pattern of the primary health care providers for the asthma was quite different from the national and international guidelines. More efforts need to be made to reduce the gap between the present pattern of asthma prescription and the guidelines.

The purpose of this study was attempted to analyze the relationship between drug abuse and the other problem behavior Patterns among high school students in Cheju. In order to achieve these set-goals, questionaires were finally supplied to the total 379 case of 9 high school from October to December, 1990. The collected data were processed using the SPSS-X computer program and statistically analyzed by the Chi-square method and. percentage. Results of the study were as follows: Among the 370 adolescents, 32.4% of students experienced cigarette smoking in their life, adolescents who experienced alcohol drinking were 46.8%, 0.5% of the students ever used marihuana; cocaine 0.3%, stimulant 3.2%, hallucinogen and inhalants 0.5%, tranquilizer 1.4%, analgesics 31:6%, antitussives 6.5%, antihistamines 1.9%. And all students never experienced the amphetamines and narcotics. The rates of drug use except stimulant and antitussive were higher in the male than in the female students. For the analysis of personal identifying datum, the rates of experienced smokers increased among groups of buddhist and the rates of experienced alconoi drinking increased among groups of no religion. Drug abuser increased among the group lower socio-economic status student, the adolescents whose parents have traditional education point of view. And it was also higher in those who were living only one than in those who were living together. Most students tended to use drugs after 17 or 18 years old. Drug users were more inclined to commit other problem behaviors when compared non-drug users. In the conclusion of the above results, it will be necessary to investigate the drug problem of adolescent. Drug abuse of students must be seen in an environmental context including family, school, peer group and society and not solely as the characteristics of an individual adolescent. And their parents and teachers must be on the alert for the behavior changes of their children such as changes of school performance, neglecting homework, tardiness or truancy from school, runaway from home, and mingled with bad companions, etc. We must recognize that drug abuse is frequently symptomatic of problems in the adolescent's environment.
