Hypertension is one of the modifiable risk factors for stroke and heart disease. Lowering blood pressure is a primary or secondary preventative measure for stroke and heart disease. There are many antihypertension drugs. But these day there comes some side effect of antihypertension drugs. Headache, sexual dysfunction, inertia, dizziness, depression, and so on. So we use Bangpungtongsung -san to stage 1 hypertensive patients. After treatment with Bangpungtongsung-san, patients showed antihypertensive effect and improvement in general condition. The result of this study suggest that Bangpungtongsung-san might be usefully applied for the treatment of hypertension.

The water extract of Gamisamryungbaekchool-San increased the lifespan of mice implanted intraperitoneally with sarcoma 180. Significant depression of lethal toxicity of cis-platin $(45{\mu}M/kg,\;s.c)$ and renal toxicity (indicated by an increase in blood urea nitrogen value and creatinine value) of cis-platin $(35{\mu}M/kg,\;s.c)$ were observed in mice and rats treated with Gamisamryungbaekchool-San. RBC and WBC were significantly decreased in rats treated with cis-platin, and significant depression of hematologic toxicities of cis-platin $(35{\mu}M/kg,\;s.c)$ in rats treated with Gamisamryungbaekchool-San. After all, alleviative effect of the side actions of cis-platin was acknowledged by combined usage of Gamisamryungbaekchool-San and cis-platin.

Attempts have been made upon the temperature response of the rat induced by some central nervous system depressants as well as stimulants, so as to secure some hidden facets of Panax Ginseng acting upon central nervous system. Although considerable works have been done with regard to Panax Ginseng, it is quite apparent that neither definite implication in terms of its effective chemical constituents is with us nor its pharmacological activity thus far. The author could, however, arrive at some results through procedures preceded by intraperitoneal administration of various drugs in combination with Panax Ginseng in albino rats, that is: (1) Nembutal and chlorpromazine displayed a highly inhibitory effect upon temperature response in the presence of Panax Ginseng, while meprobamate, reserpine, phenacetin and aspirin exerted potentiation actions upon hypothermia. Phenobarbital, serotonin and histamine, on the contrary, did not appear to produce any effect of significance. (2) Nembutal with Panax Ginseng caused prolongation of hypnosis in rat, whereas sodium phenobarbital did not have any effect on it. (3) $LD_{-50}$ in each experimental group of administration of central nervous system stimulants such as strychnine, picrotoxin with Panax Ginseng, necessitated marked increase in the lethal doses. The observations from this study seemed to imply that the complicated mechanism of action of Panax Ginseng might be referred to both central nervous depressive action and influence to basal metabolic rate of mammalian.

Etomidoline is a new synthetic atropine-like drug. The present investigation aimed to study the combined effects of etomidoline and neofopam hydrochloride which has an analgesic and muscle relaxant activity, compared with the effects of each drugs. Acute toxicities (ID$_{50}$) in mouse were 132mg/Kg (p.o.) and 49mg/Kg (i.p.) when combination ratio of etomidoline and neofopam was 1:5 and 103 mg/Kg (p.o.) and 30mg/Kg (i.p.) with the ratio of 1:10. Etomidoline showed more potent anticholinergic effects than neofopam in the isolated rat intestine. Whereas, antibarium effects were twice as active with neofopam than with etomidoline. When etomidoline and neofopam were added in combination ratio of 1 : 5, papaverine-like avtivity was increased, but no changes of anticholinergic effect were observed. Analgesic effect was measured by the anti-writhing method of Whittle in mice. Both of the concurrent and single administration of etomidoline and nefopam reduced significantly the writhing number and the effect of the concurrent administration was more active than that of single, and 1 : 5 combination was slightly more potent than 1:10. Each drug or the combined drug was administered to mice and observed the change of the pupil size. Pupil sizes were increased with each drug and with combined drug, although there were no significant differences between the each group of drugs. However, those effects were less than that of atropine sulfate.e.

Chaga mushroom (Inonotus obliquus) extract has been known to have therapeutic effects, such as anti-inflammatory, hepato-protective, anti-oxidant and anti-tumor effect. In this study, we evaluated the effects of Chaga extract on the cytotoxic actions of cisplatin in HepG2 hepatoma cells. The viability of the HepG2 cells was decreased to 10% at 3 ${\mu}M$ cisplatin and to 20% at 500 ${\mu}g$/ml Chaga extract as measured by the MTT assay. The viability of HepG2 cells co-treated with cisplatin (3 ${\mu}M$) and Chaga extract (500 ${\mu}g$/ml) was decreased to 50% in compared with the control cells. The cytotoxicity of two drugs was revealed as apoptosis characterized by the chromatic condensation, nuclear fragmentation and the cleavage of pro caspase-3 in HepG2 cells. Also, the cells treated with combination of two drugs showed synergistically the loss of mitochondrial membrane potential and increase of intracellular ROS levels. Therefore, these results suggest that the combination treatment of cisplatin and Chaga extract induces apoptotic cell death in HepG2 cells and has more potential anti-tumor effect than cisplatin alone.

Glycyrrhizin (GA) content in licorice was determined by a couple of methods using HPLC, respectively. In Method(I), GA content itself was determined from the licorice aqueous extract, while in Method (II) glycyrrhetinic acid (GHeA ; the aglicone of GA) content corresponding to the quantity of GA was measured from the chloroform extract of the hydrolyzed product of licorice aqueous extract. A reverse phase column Hibar Lichrosorb RP-18 (E. Merck) was used as the stationary phase. As the mobile phase MeOH: $H_{2}O$(0.05M-$NaH_{2}PO_{4}$)=58 : 42 solution in Method (I), and MeOH: $H_{2}O $: AcOH=78; 19: 3 solution in Method (II) were suitable, respectively. The value obtained by Method (II) appeared slightly higher than that by Method (I). The effect of some other herbal drugs on the assay of GA quantity in mixed sample was also observed in both above two methods. By Method (I) Cassiae Cortex, Rehmaniae Rhizoma, Paeoniae Radix, and Angelicae Radix gave the subtractive effect on the amount of GA compared with the value from licorice alone. In the case of Method (II) Cassiae Cortex and Rehmaniae Rhizoma appeared to have subtractive effect but Paeoniae Radix and Angelicae Radix scarcely showed any influence. Pachymae Fungus did not affect the GA content at all. It seems that glycyrrhizin in licorice interacts with certain components of other herbal drugs.

Luteolin and chicoric acid are the most abundant phytochemicals in dandelion (Taraxacum officinale) leaf. In this study, four kinds of extraction methods [hot water, ambient temperature (AT) water, ethanol, and methanol] were applied to analyze the contents of both phytochemicals and verify their anti-inflammatory and antioxidative activities. The methanol extract showed the most potent nitric oxide (NO) inhibitory effect. The luteolin and chicoric acid concentrations were 3.42 and $12.86\;{\mu}g/g$ dandelion leaf in the methanol extract. The NO-suppressive effect of luteolin and chicoric acid was identified in a dose-dependent manner with $IC_{50}$ values of $21.2\;{\mu}M$ and $283.6\;{\mu}M$, respectively, in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells without cytotoxicity. Malondialdehyde (MDA) concentration, as an index for free radical injury on cell membrane, was also dose-dependently inhibited by the two compounds. The suppressive effect was further examined using mRNA and protein expression levels, which were attributable to the inhibition of inducible nitric oxide synthase (iNOS). These results suggest that two phytochemicals in dandelion leaf, luteolin and chicoric acid, may play an important role in the amelioration of LPS-induced oxidative stress and inflammation.

Caffeine is a xanthine alkaloid derivative found in many foods and beverages. Dietary caffeine may interact with commonly-consumed over-the-counter (OTC) drugs in body. In this study, cytotoxic effects on the intestinal cells by combined treatment of caffeine with several OTC drugs, including ibuprofen, aspirin, and acetaminophen. Cytotoxic effect of caffeine was more potent in normal intestinal INT 407 cells than in colon cancer HCT 116 cells. Relative toxicity of caffeine and the OTC drugs was significantly enhanced in INT 407 cells when treated together. Intracellular thiol levels of the cells treated with the OTC drugs increased in the presence of caffeine. When HCT 116 cells were incubated with each OTC drug after or before caffeine treatment, the relative cytotoxicity of the OTC drugs increased. The present study may provide basic information about possible health effects through the interactions between caffeine and OTC drugs in the intestinal cells.

Liver is an important target of the toxicity of drugs, xenobiotics and oxidative stress. Acetaminophen pverdose causes acute liver injury in both humans and animals. This study was performed to observe the effect of sachunwhan and its component groups on recovery of hepatoxicity in acetaminophen treated rats. The experimental group was divided into 4 groups: sachungwhan(SC), samultang group(SC-1: 當歸, 川芎), chungyul group(SC-2: 龍膽草, 大黃, 梔子), and haepyo group(SC-3:羌活, 防風). Under the same condition Normal group was fed basal diet and water; Control group was injected acetaminophen and fed basal diet for 2 weeks; Experimental groups were injected acetaminophen and fed each extracts for 2 weeks respectively. The results were obtained as follows: 1. In the study on antioxidative defense system in vivo, SC reduced the amount of lipid peroxide in both serum and liver and showed activity on antioxidative enzymes such as catalase, glutathion. Other groups had effect only on glutathion. 2. In the study on hepatotoxicity(GOT, GPT, ${\gamma}$-GTP, ALP, LDH, Bilirubin), SC had a significant effect on recovery of hepatoxicity in acetaminophen treated rats. Other groups had no effect except SC-1 having effect on ${\gamma}$-GTP. As results shown, only Sachungwhan(SC) has significant effects on recovery of hepatoxicity and antioxidative defense system in vivo. These results suggest that Sachungwhan(SC) made antioxidative defense system active and it seemed to be very important to its effect on recovery of hepatoxicity. In the other hand, Component groups had no effect on recoverv of hepatoxicity and antioxidative defense system in vivo. This was thought that component drugs' cooperative synergy effect would be important to Sachungwhan(SC)'s effects mentioned in this paper.

The survey with questionnaire were conducted to grasp the actual condition of four cautious drugs-antibiotics, sedative hypnctics, mincr tranquilizer, analeptics-self -medication behavior through drugstore use and to analyze the primary factors connected with it. The following six objectives were established. 1) To catch the reason why the man who medicate himself buy four cautious drugs at a drugstore, and to know the choice motive of each drug purchased. 2) To grasp the distribution of four cautious drug taken by the man who medicate himself and to analyse the reason of taking the drug. 3) To find out whether the buyer has taken the same drug past and to know the duration and the frequency. 4) To grasp the degree of recognition about four cautious drugs and the attitude toward continuous taking them. 5) To analyze the degree of recognition about the influence on human body and the attitude of medication behavior. 6) To know "the experience of side-effects" and to grasp the kind of the side-effects. The data were collected from 15 drugstores with 677 respondents in seoul from August 17 to september 21, 1987. The following results were obtained. 1) The reasons for drugstore use were first, "for easy access and convenience" (53.7%) second, "for the slightness of illness" (19.9%) third "for the cheap price" (13.2%). According to that result, the factor of "the easy access of drugstore" was most influential. In case of the poor, the factor "for the cheap price "was revealed second (37.3%). And "for the slightness of illness" was second reason in the medically insured (22. 9%), "for the cheap price" was second reason in the others (29%). 2) The kind of drugs purchased were antibiotics (62.8%), analeptics(17.2%), minor tranquilizer(13.3%) and sedative hypnotics (6.7%) on the whole. In teenagers, besides antibiotics the percentage of taking analepits came second (42.4%) and it was revealed that the percentage of sedative hypnotics, minor tranquilizer increase with age. But in proportion to the increase of age, the taking of analeptis decreased. 3) The choice motives of each drug purchased were all different. In case of antibiotics "recommendation of pharmacist" was 39.6%, sedative hypnotics "recommendation of pharmacist" and "my own judgement", 28.9%, respectively, minor tranquilizer "my own judgement", 35.2%. and in case of analeptics "my oun judgement" was most common with 53.5%. 4) The reasons for taking drugs were as follows. antibiotics was taken for the inflammation mitigation of a wound and a swelling (38.5%), sedative hypnotics for the removal of insomnia (97.5%), minor tranquilizer because of restlessness and qloominess(39.3%), and analeptics for the shortening of sleeping hours (35.1%). 5) Those experienced in taking four cautious drugs were 78.2% on the average. It was revealed that antibiotics use duration was "from one week to one month" (38.9%), the frequency was "rarely" (62.1%), sedative hypnotics and minor tranquilizer; "More than three years", (35.7%, 30.4%), respectively, "Somtimes", (43.8%, 35%), respectively. analeptics ; "from one year to three years", (27.6%), "Sometimes", (42.7%). 6) In regard to the source of information in taking drugs, 35.3 percent of male were relied on "recommendation of pharmacist", 32.6 percent of female "my own judgement", There was a difference between below the middle school graduates and over the high school graduates Thease were relied on "recommendation of pharmacist" first, those "my own judgement" first. And "my own judgement" was the first source of specialist(40%), labours(41.4%), salesman(43.5%), and jobless men(36.8%), "recommendation of ralatives on friends" was the first source of students (30.4%), "recommendation of pharmacist" was the first soure of teachers, administrative office workers (39%) and housewives (40.7%). 7) The degree of recognition about four cautious drugs was as follows. "know a little" was (43.0%), "don't know" (30.2%), "know" (26.8%), respectively. In regard to the attitude toward continuous taking them, it was revealed that "I will take it according to circumstamces" was first (56.2%), " I will not take it as possible" was first(56.2%), "I dont know well" (12.9%), "I will take it continuously" (8.3%). 8) About the influence on human body, "if proper, it is effect" was common attitude toward antibiotics (43.6%), "Probably bad influence on the health" was first toward the other drugs (46.2%), In terms of the degree of observance to taking-time and dose of drugs, "suitably" was first (37.3%), "relatively correctly" second (27%), "correctly" (17%). 9) The percentage of four cautious drugs side-effects was 27.5 on the average. The kind of side-effects were eruption and urticaria (28.5%), heart acceleration and so forth. (25.4%), headache and Giddiness, dyspepsia (23%), respectively.
