  • Crinum asiaticum var. japonicum is a wild plant growing only in Jeju-island, Korea, and in Japan. The whole part of this plant has been known to have the pharmacological actions such as analgesic, anti-inflammatory, platelet-aggregation inhibitory, antitussive, and expectorant. With these assumed actions, the leaves (Crinum folium) of this plant has been used in the folk remedies for arthritis and arthralgia. There is, however, no scientific evidences for the pharmacological actions of Crinum asiaticum var. japonicum. In the present study, the analgesic, anti-inflammatory, and platelet-aggregation inhibitory actions of Crinium folium were evaluated using writhing test, tail-flick test, carrageenin antiedema test, in vitro thromboxane $B_2$ quantitation assay and in vitro platelet aggregation test. In order to obtain the partially purified fraction whose pharmacological action is excellent, the methanol extract of Crinium folium was fractionated consecutively into four biological fractions such as ether, ethyl acetate, butanol, and water fractions and their pharmacological actions of the fractions were investigated. Putting our results together, Crinium folium, especially ethyl acetate fraction was proven to have significant analgesic, anti-inflammatory and platelet-aggregation inhibitory actions by inhibition of prostanoids biosynthesis as one of its mechanism of action.

  • This study was designed to assess Effects of jingansikpungtanggagam-bang on Central Nerve System. Method : jingansikpungtanggagam-bang, a Korean traditional prescription, was evaluated for its anticonvulsant effect, hypnotic activity, analgesic action, anxiolytic effect, memory enhancement, and MAO inhibitory activity and detennined the content of neurotransmitter in brain by HPLC method. Result : 1. The extract increased potently anticonvulsant effect at 1g/kg by 5.6-fold extention of onset time against control group. 2. The extract increased hvrmsis at 500mg/kg by over twofold length of sleeping time compared to control. 3. The extract showed a significant analgesic effect with 86.0% inhibition on writhing frequency at 500mg/kg by phenylquinone-induced writhing test. 4. The extract inhibited dose-dependently the activity of monoamine oxidase in vitro. 5. This prescription increased the brain levels of serotonin and 5-hydroxyindoleacetic acid by 3.3% and 1.4%, respectively. 6. the extract exhibited the anxiolytic effect with 21.3% decrease of the immobility duration against control group. 7. the extract enhanced memory recovery on scopolamine-induced impairment of passive avoidance performance at 1g/kg pretreatment with 20.2% increase of latency time. Conclusion : The result sugguest that jiugansikpungtanggagam-bang can be used effectively as a sedative prescription in Korean traditional medicine.

  • Background : The location of acupoints on rat, which may differ from that of human body due to anatomical structure, is defined variously among researchers, which may cause the problem of low repeatability and objectivity. Design : The measurement of hind limb consist of measuring the distance between knee joint and tibia tubercle in order to set the knee joint as common criteria. Based on it, the three mostly referred location of ST36 were represented with the knee joint as a datum point and compared. The electroacupuncture stimulation was administrated after the abdominal pain was induced by acetic acid. And the analgesic activity of each ST36 acupoint was evaluated by measuring the number of writhing reflex, in order to observe the differences of treatment effect in accordance with the location of ST36 acupoints. Results : The result of measurement confirmed the differences in the acupoint location of ST36 among researchers. The writhing reflex test using the acetic acid-induced abdominal pain stimulated with electroacupuncture of 100Hz showed that there were statistically significant differences in the analgesic effect between control group and three ST36 groups (P<0.05). However there were no differences observed among three mostly referred location of ST36 acupoints (P>0.05). Conclusions : We recommend "the point located 6.5 mm below the knee joint at the anterior tibial muscle" as a standard ST36 acupoint location qualified by the WHO Standard Acupuncture Point Locations in 2008.

  • General pharmacological properties of (R)-JG-381 were examined in laboratory animals to investigate its safety profile. Administration of (R)-JG-381 (50 and 100 mg/kg) in mice and rats had no effects of general behaviors, central nervous system of the animals in test systems of pentobarbital-induced sleeping time, writhing syndromes induced by 0.7% acetic acid, chemo-shock produced by pentylenetetrazole, and, however, had mild effects on motor coordination. Heart rate and blood pressure were not changed by (R)-JG-381 treatment. (R)-JG-381 also showed mild effects on intestinal propulsion and gastric secretion. These results suggest that (R)-JG-381 dose not exert serious pharmacological effects.

  • Roots of Rumex crispus (Rc) (Polygonaceae) has been used as therapeutic agents of acute and chronic cutaneous diseases, cathartics, fever and jaundice in folk medicines. Recently, Seeds of Rc has known as a digestive, an anticancer agent and a remedy of acute hepatitis, among many traditional folk medicines. So far it isn't reported about pharmacological effects of Rumecis Semen. The present study describes the preliminary evaluations of biological activities, anti-inflammatory activity (AA, Carrageenan) analgesic activity (writhing test), and hepatoprotective activities ($CCl_4$), of its methanol extract, ethyl acetate fraction and butanol fraction. Among them butanol fraction showed the highest activity in analgesic acivity.

  • The synthesis of phenoxyalkanoic acid derivatives and their anti-inflammatory and analgesic activities are described. Analysis of structure-activity relationships shows that in trichlorophenoxy derivatives anti-edematous potency is associated with the presence of 1-thiopropyl moiety and 2 or 40aminopyridyl moiety at $R^{l}$ position contributes to the analgesic activity.

  • The crude methanolic extract of the bark of Cerbera odollam Gaertn. was evaluated for its possible antinociceptive and neuropharmacological activities in animal models. At the dose of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive effect in acetic acid induced writhing in mice comparable to that produced by aspirin, used as standard drug (P<0.001). The extract significantly reduced the time of onset of sleep (P<0.01) and potentiated the pentobarbital induced sleeping time in mice at the dose of 400 mg/kg of body weight significantly (P<0.001). It also decreased the open field score in open field test significantly at the dose of 400 mg/kg of body weight (P < 0.05). The obtained results tend to suggest the probable antinociceptive and neuropharmacological activities of the crude extract.

  • Previously, we have reported that the butanol fraction of the head of Panax ginseng had significant gastroprotective activity on gastritis and gastric ulcer models of rats. Considering the safety of the fraction for development of new anti-ulcerative agent or food supplement, general pharmacological study was carried on. The fraction was revealed that have no influence on spontaneous activity, phenobarbital-induced sleeping time, rotarod test, body temperature, gastro-intestinal motility, respiration and blood pressure. The fraction showed weak analgesic action in writhing syndrome and did not show any sign of acute toxicity in mice.

  • The pharmacological interest coupled with traditional uses (antidiarrhoeal, antiseptic, analgesic etc) prompted us to test for anti-inflammatory, antinociceptive and diuretic activitities of Trema (T.) orientalis Linn. The crude methanolic leaves extract of T. orientalis was investigated for its possible anti-inflammatory activities using carrageenin induced rat paw edema model and cotton pellet implantation method in mice. Then the extract analyzed for its antinociceptive activities by acetic acid induced writhing model in mice. The extract possessed significant anti-inflammatory activity in both models at the doses of 200 and 400 mg/kg body weight of mice. Moreover, the extract showed significantly reduced the number of acetic acid-induced abdominal constriction in mice of 200 and 400 mg/kg body weight. The extract also showed positive diuretic activity in albino mice.
