  • The effect of alcoholic extract of Anthocephalus (A.) Cadamba Roxb. was evaluated in experimental models of pain and ulcer. Hot tail flick test, hot plate test and acetic acid induced writhing test were employed for evaluating the peripheral as well as central analgesic mechanism exerted by the extracts. Gastroprotective activity was examined by HCl and ethanol induced gastric damage test. Test group received crude extract 500 mg/kg showed maximum time needed for the response against thermal stimuli (6.26 ${\pm}$ 0.439 s) which is comparable to diclofenac sodium (6.56 ${\pm}$ 0.381 s) in hot tail flick method. These experimental results also followed the experimental results of hot plate test where crude extract 500 mg/kg showed maximum time needed for the response against thermal stimuli (4.74 ${\pm}$ 0.234 s) which is comparable to diclofenac sodium (5.58 ${\pm}$ 0.585 s). The crude extract at 500 and 250 mg/kg showed significant reduction in acetic acid induced writhing in mice with a maximum effect of 68.026% reduction at 500 mg/kg dose which is comparable to standard diclofenac sodium (79.93%). In gastroprotective study the extract of A. Cadamba (250 and 500 mg/kg) significantly inhibited ulceration induced by both HCl and ethanol dose dependently. Results of the study suggest that the extract possesses both analgesic and gastroprotective activity on mice.

  • 새로 분리된 곰팡이 Trichoderma erinaceum DG-312의 균사체 배양에 의해 갈락토만난(GMs)을 생산하여 쥐에서 항염증 활성을 조사하였다. 5 리터 교반 발효조에서 3일 동안 배양에 의해 얻어진 균사체 및 갈락토만난의 최대 농도는 각각 9.44 g/l 및 2.72 g/l 이였다. Sepharose CL-6B 젤 크로마토그라피와 다당체 성분 분석 결과, crude 갈락토만난의 조성은 주로 mannose $(74.9\%)$와 galatose $(24.1\%)$로 구성된 이종의 다당체인 것으로 밝혀졌다. Trichoderma erinaceum DC-312로부터 생산된 갈락토만난은 아세트산으로 처리한 쥐에서 체중(kg)에 대하여 100 또는 200 mg의 양으로 처리하였을 때 농도에 비례하여 현저한 항 염증 활성을 갖는 것으로 나타났다. 갈락토만난의 항염증 활성을 나타내는 모세혈관 투과도(vascular permeability) 및 발작 반응(writhing response)의 저해 수치는 각각 $60.6\%$$62.5\%$로 나타났다. 따라서 이런 갈락토만난의 항염증 및 발작반응 저해에 효과적인 특성을 이용한다면 치료 목적을 위한 의약물질 개발의 잠재성을 보여준다.

  • Effects of Allolobophora caliginosatrapezoides (Ac) polysaccharide fractions on the inflammation and hypersensitivity were studied in vivo. It showed that Ac polysaccharide fractions have the significant inhibitory activities of inflammation and hypersensitivity; They inhibited significantly the carrageenin-induced paw edema and acetic acid-induced writhing syndrome. They also inhibited significantly the Arthus reaction and delayed hypersensitivity in the sheep red blood cell-sensitized mice in accordance with the inhibition of haemaglutinin titer, haemolysin titer, plaque-forming cells and rosette-forming cells. They also improved markedly the oxazolone-induced dermatitis in rats dose-dependently. As the above results, it exhibited that Ac polysaccharide fraction inhibited not only humoral immune response, but also cell-mediated immune response. It seemed that methanol and ether extracts have also another physiological active agents.

  • The Woo-Whang-po-Lyong-Whan has been used as one of the traditional medicines in the field of pediatrics so far since Song dynasty, and still it is widely being used nowadays. It might be considered to be a contribution to do further basic experimental studies on antipyretic, anticonvulsive and analgetic action of the Woo-Whang-po-Lyong-Whan. So it's pharmacological studies were carried out comparing to control drugs. ?Following conclusions were obtained. 1. It's antipyretic action was compared to that of aspirin by Writhing response using acetic acid-method. Mice were given one twentith, one tenth and one fifth tablets of the Woo-Whang-po-Lyong-Whan per Kg of body weight, respecitively. Writhing syndrome frequencies were noted as 38.4 in control group. and $18.0{\pm}12$, $13.17{\pm}2.28$, $7.33{\pm}12$ in above esperimental groups, respectively. In aspirin group it was $18.5{\pm}1.0$ when 2mg aspirin per body weight of mice was given. So it was recognized that antipyretic action of the Woo-Whang-Po-Lyong-Whan become remarkable by increasing amounts of the Woo-Whang-Po-Lyong-Whan. ?2. Antipyretic action in normal temperature mice group was not significant by increasing concentration of the Woo-Whang-Po-Lyong-Whan, but body temperature dropping in normal mice group was slightly noted than control. group, but less temperature dropping was noted than aminopyrin group. ?3. In fever provocated rats groups using Salmonella typhimurium, antipyretic action of the Woo-Whang-Po-Lyong-Whan was not observed significantly than control group. And slight antipyretic action was noted in aminopyrin group. So that antipyretic action of the Woo-Whang-Po-Lyong-Whan was not significant than those of general antipyretic used nowadays, but slower action was recognized. ?4. Anticonvulsive action of the Woo-Whang-Po-Lyong-Whan was studies comparing to that of phenobarbital. Action was not remarkable than phenobarbital, but was significant than control group. No significant intesifying action was noted by increasing amounts of the Woo-Whang-Po- Lyong-Whang.

  • Benorylate and ethoxybenzamide have been used alone or in combination as an analgesic, antipyretic and antiinflammatory agent. We investigated the significance of the differences of analgesic activities between single and concurrent administration of benorylate and ethoxybenzamide and lorazepam in mice and also antipyretic activity between single and concurrent administration of benorylate and ethoxybenzamide in rats. 1). Concurrent administration of each half dose of benorylate and ethoxybenamide showed much inhibiting effect on the acetic acid-induced writhing syndrome of mice than the above drug alone, and the some increased analgesic response by hot plate method. 2). The synergistic and analgesic effect of combined administration of benorylate and lorazepam was found to be significant. 3). Antipyretic effect of half-dose combined administration of benorylate and ethoxybenzamide on the rat pyrexia induced by yeast(s.c.) and T.T.G. (i.v.) was shown to be similar to the effect of each drug.

  • This study has been carried out to investigate general pharmacological action of bamboo salt (jukyom) in terms of effects on central nervous system and cardiovascular system in experimental animals. After bamboo salt, crude salt or reagent-grade NaCl were orally administered into male ICR mice with dose of 2.0 g/kg, general behavioural syndromes such as body weight and locomotor activity, spontaneous motor activity, pento-barbital-induced sleeping time, muscle incoordination, electroshock-induced convulsion, body temperature and writhing response caused by 0.6% acetic acid solution were observed. Bamboo salt had no influences in these indices for examinition of effect on central nervous system. Additionally, conscious male Sprague Dawley rats fastened overnight won ere treated with bamboo salt, crude salt or reagent-grade NaCl (2.0 g/kg, p.o.) to examine the effect of these salts cardiovascular system. Systolic, median and diastolic food pressure and heart rate were dertemined using tail cuff indirect method. Treatment with Hydralazine (50 mg/kg, p.o) as a positive control produced the decreases in systolic, median and diastolic blood treasure and an increase in heart rate. whereas no changes were observed in bamboo salt, crude salt and reagent-grade NaCl treated groups. These results strongly suggest that bamboo salt may have no effects on general pharmacology of central nervous systems and cardio-vascular systems.

  • The pharmacological activities of the acetonitrile (MeCN), hexane extracts and isolated pure terpenoidal compound Lupeol from the leaves of Teclea nobilis, Delile (TN), on inflammation induced by carrageenan an implantation of cotton pellets in rats; the nociceptive response using writhing and tail flick tests and the antipyretic activity in yeast-induced fever were examined in mice. Oral administration of TN extracts at doses of 150 and 300 mg/ks and lupeol 5 and 10 mg/kg showed a significant anti-inflammatory activity in rats. The extracts of TN and lupeol significantly decreased the number of contractions and stretchings induced by acetic acid and heat-induced pain in mice. The antipyretic effect of extracts and lupeol was also found to be significant. The behavioral observation of animals showed that the hexane extract and lupeol caused CNS depressant activity and did not produce any toxic or lethal effects in animals at various dose levels. The results suggest that the Teclea nobilis extracts and lupeol possesses anti-inflammatory, analgesic and antipyretic activities.

  • Ulmus parvifolia has been used as a traditional folk medicine to treat the carbuncle in deep skin. In this study, the effect of water extract of root bark of Ulmus parvifolia (WUP) on the carbuncle, pain, inflammation and hypersensitivity was evaluated in animal models. The administration of WUP significantly decreased the size of Staphylococcus aureus ($10^8$ cells/mouse)-induced carbuncle, and also exhibited analgesic activity in the HAc-induced writhing syndrome at doses of 50-500 mg/kg. It also showed significant anti-inflammatory activity in the carageenin- and complete Freund's adjuvant-induced inflammation. In the histamine-induced anaphylaxis, it decreased the percent of mortality by protecting mice treated with Bordetella pertussis. In the immune responses in the mice sensitized and challenged with sheep red blood cells, the Arthus reaction determined by swelling of foot pad at 4 h after challenge, HA titer, HY titer and PFC which can be used to evaluate the humoral immune response were significantly suppressed by oral administration of WUP at doses of 100 and 200mg/kg. The cellular immune responses in the same mice such as delayed type hypersensitivity determined by swelling of foot pad at 24 h after challenge and RFC were also significantly suppressed in the same manner.
