  • Nelumbo nucifera(NN) is a oriental medicinal herb which has been used traditionally for the treatment of antidiarrhea, sedative action and various brain diseases including convulsion and epilepsy. In order to examine the mechanism of anticonvulsive effect, we treated the methanol extract of NN(100, 200 mg/kg, P.0) to the sleeping time and pentylenetetrazole(PTZ)-induced convulsive mice. The methanol extract of NN prolonged sleep time by pentobarbital. Methanol extracts of NN were not effected the concentration of GABA and GABA-T activity in the brain of PTZ-induced mice. Methanol extracts of NN significantly inhibited the convulsion state as well as the level of lipid peroxidation in the brain. The butanol and dichloromethane fraction of methanol extracts among the others effectively inhibited in vitro lipid peroxidation dose dependently($5.0{\times}10^{-6}\sim2.0{\times}10^{-5}\;g/ml$). These results suggest that the anticonvulsive effect of NN is possibly due to the antioxidative effects of the free radical formation at brain for the PTZ-induced convulsion if it were by due to generating system.

  • In order to investigate pharmacological properties of New Wonbang Woohwangchungsimwon Pill (NSCH) and Wonbang Woohwangchungsimwon Pill (SCH), the effects of NSCH and SCH on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in mongolian gerbils. The histological observations showed preventive effects of NSCH and SCH treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by SCH treatment. In contrast to what was inhibited by NSCH and SCH treatments. While NSCH and SCH had no effects on the hexobarbital-induced sleeping time, they prevented the seizures induced by electric shock and strychnine. NSCH and SCH showed sedative effect in rotarod and spontaneous activity test. Furthermore, NSCH and SCH showed anti-stress effect. Our findings suggest that the pharmacological profiles of NSCH on cerebral ischemia and central nervous system are similar to those of SCH.

  • The effect of Ruthenium Red on the antinociceptive action of capsaicinoids was investigated using tail-flick test in mice. Capsaicin and KR-25018, when administered subcutaneously, had a potent antinociceptive effect against noxious heat stimulus. Ruthenium Red which is known to block the calcium channel coupled to the capsaicin receptor, when injected intraperitoneally more than 5 mg/kg, showed severe sedation and apparent antinociceptive effect against noxious heat stimulus. The 2.5 mg/kg Ruthenium Red, at which dose any significant sedative effect was not shown, had no effect on the antinociceptive effects of capsaicin and KR-25018. Considering this result, the antinociceptive effect of capsaicinoid may not be related to the Ruthenium Red sensitive calcium channel which is activated by capsaicin.

  • Recently combining regimen of minimal doses of chloral hydrate, hydroxyzine and midazolam is good in sedation of children. Midazoalm, water soluble benzdiazepine, has rapid onset and relatively short duration of action. And midazolam has prospective amnesic effect. With these advantages midazolam is popular in conscious sedation for children. This study was to reveal the dose-dependency of behavior and physiologic effects of submucosal midazolam. Sedation records were surveyed retrospectively, of which the patients admitted from April, 2005 to July, 2007. we assigned three groups according the dose of midazolam, 0.1 mg/kg, 0.2 mg/kg and 0.3 mg/kg, respectively and the behavioral evaluation was analyzed with Houpt scale statistically. Combined submucosal midazolam increased the success rate in sedation and the vital signs were stable during sedation.

  • Tiliacora racemosa Colebr. belonging to the family Menispermaceae is the biggest store-house of diphenyl bisbenzylisoquinoline (DBBI) alkaloids. Exhaustive chemical processing of the root of T. racemosa by the application of modern separation techniques yielded a DBBI alkaloid which was identified as tiliacorine using sophisticated spectroscopic methods (UV, IR, $1^H-NMR$, Mass). Tiliacorine potentiated the sleeping time induced by standard hypnotics viz. chlorpromazine (CPZ), pentobarbitone (PB) and diazepam (DZ) in a dose dependent manner. Tiliacorine potentiated the analgesic action of standard analgesic agents viz., morphine and meperidine. It was also found to possess anti convulsive activity in the strychnine induced convulsion model.

  • It was previously indicated that 'Samulanshintang' had been examined for effects of the anticonvulsive, antipyretic, analgesic, sedative and antispasmodic actions. In order to investigate the effect on the cardiovascular system and anemic rabbits induced by phenlhydrazine HCl, pharmacological studies have been carried out with extract. The results of this investigation were summarized as follows: The relaxation of bronchial smooth muscle and antihistamine action were recognized. Antihypertensive and vasodilating actions due to vascular smooth muscle relaxation were noted in frogs and rabbits. 'Samulanshintang' lowered the rate of anemia induced by phenylhydrazine and rapidly recovered from the anemia state.

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.

  • Acanthopanax koreanum Nakai (Araliaceae) is a medicinal plant indigenous to Korea. The root and stem barks of Acanthopanax species have been used as a tonic and sedative as well as in the treatment of rheumatism and diabetes. In our study, three lignans, eleutheroside E (EE), tortoside A (TA), and syringaresinol (SY), were isolated from the stem and root of A. koreanum in an effort to study the immunomodulating effect. We treated natural killer cells and dendritic cells with lignans (EE, TA, or SY), and analyzed their cytokine (IL-12 and IFN-${\gamma}$) secretion. EE, TA, or SY markedly enhanced IL-12 secretion in mouse lymphoid (DC1) and myeloid type (DC2.4) dendritic cells after 48 hr of treatment. There were no significant differences in the cytokine stimulatory effects between EE, TA, or SY. Moreover, treatment of EE, TA, or SY significantly induced IFN-${\gamma}$ secretion by human NK cells (NK92MI) confirmed by ELISA assay. This study suggests that lignans from A. koreanum modulate cytokines, and that such modulation may provide the mechanism of action for many of their therapeutic effects.
