  • In order to investigate the pharmacological action of combined preparation of crude drugs, 'Oyo-Tang' were studied. 'Oyo-Tang' consist of Glycyrrhizae Radix, Ephedrae Herba, Armenicae Semen, Platycodi Radix and Nepetae Herba. They have widely been prescribed in Oriental Medicine for controlling of cough, asthma, nasal abstraction, pharygeal pain and hoarseness. Experimental studies were implemented on analgesic, sedativc, anticonvulsive and ileum relaxing actions. The results of the studies were as follows; Significant anticonvulsive action was recognized by fraction IIII. Sedative and analgesic actions were noted by fraction I and III. Relaxing action was shown on the extracted ileum in mice, antagonistic actions were seen on $BaCl_2-induced$ contraction of the ileum of mice and Histamine-induced contraction of the ileum of guinea-pigs that the relaxing effect of the intestinal smooth muscle was recognized.

  • Gastrodia elata is a medicinal plant which has been used as anticonvulsant in Korea, Japan and China. This study was conducted to examine the action mechanism of Gastrodia elata centering around the change of GABA and glutamic acid level in brain while observing the anticonvulsive effect in PTZ-induced seizure model. Seizures were reduced effectively by pretreatment of ether soluble part of methanol extract of Gastrodia elata. The pretreatment of ether soluble part inhibited not only the decrease of brain GABA level but also the increase of brain glutamic acid level observed in PTZ model of convulsive dose. Although there was not any change in glutamic acid level, the same development was also observed in the model of subconvulsive dose. From above results, it seems that the anticonvulsive component of Gastrodia elata is lipophilic, and its action mechanism is originated from both control action of GABA level and inhibition of glutaminergic neurotransmission.

  • In order to investigate experimentally the effects of Taeumin Handayolsot'ang and Gamihandayolsot'ang, experimental studies were conducted about antipyretic effect, analgesic effect, antiinflammatory effect of edema, sadative effect, anticonvulsive effect experimental animals (mice and rats). Sample A group was a solid extract of Handayolsot'ang treated group. Sample B group was a solid extract of Gamihandayolsot'ang treated group. The results were summarized as fallows. 1. In antipyretic action by yeast method, sample A group was decreased significantly and sample B group showed decreasing tendency, but showed no significance. 2. In the effect of control for writhing syndrome by the acetic acid stimulating method, sample B group was repressed significantly and sample A group showed repressing tendency, but showed no significance. 3. Antiinflammatory action by carrageenine edema method was showed significant effect at all sample groups. 4. Sadative effect by rotor rod method in rats was not noted at all sample groups. 5. In anticonvulsive action by E C T unit method, time to death in mice was significantly prolonged at all sample groups. According to the above results, it is considered that Taeumin Handayolsot'ang and Gamihandayolsot'ang will be effective on pyretic diseases.

  • Ssangwhatang which has been known to have antipyretic, analgesic and antifatigue effects are composed of Paeoniae Radix, Angelicae gigantis Radix, Astragali Radix, Rehmaniae Radix, Cnidii Rhizoma, Cassiae Cortex, Glycyrrhizae Radix and Puerariae Radix. Effects of some formulations of Ssangwhatang were studied with respect to the analgesic, antipyretic, hypothermic, anticonvulsive and antiinflammatory actions in experimental animals. The results obtained were as follows: 1) Prescription A, B, C and D of Ssangwhatang were showed significant analgesic effect by the acetic acid stimulating method in mice. 2) All Ssangwhatang-prescriptions used in this studies had hypothermic effect in normal mice. 3) Significant antipyretic effect in febrile rabbits were recognized in prescription A and C of Ssangwhatang, while not in prescription B and D of Ssangwhatang. 4) Prescription A, B, C and D of Ssangwhatang showed marked antiinflammatory effect against the edema induced by carrageenin in rats. 5) Prescriptions of Ssangwhatang did not show significant anticonvulsive effect against the convulsion induced by picrotoxin and strychnine in mice. From the above results, analgesic, hypothermic, antipyretic and antiinflammatory effects were recognized in Ssangwhatang. Ssangwhatang A- and C- prescriptions added with Pueraiae Radix showed better effects than prescription B and C of Ssangwhatang.

  • Long QT syndrome is a cardiac repolarization disorder and is associated with an increased risk of torsades de pointes. The acquired form is most often attributable to administration of specific medications and/or electrolyte imbalance. This review provides insights into the risk for QT prolongation associated with drugs frequently used in the treatment of chronic pain. In the field of pain medicine all the major drug classes (i.e. NSAIDs, opioids, anticonvulsive and antidepressant drugs, cannabinoids, muscle relaxants) contain agents that increase the risk of QT prolongation. Other substances, not used in the treatment of pain, such as proton pump inhibitors, antiemetics, and diuretics are also associated with long QT syndrome. When the possible benefits of therapy outweigh the associated risks, slow dose titration and electrocardiography monitoring are recommended.

  • In order to investigate experimentally the clinical effects of Soumin Kamikop'ungsan (少陰人 加味祛風散) that was prescribed to cure the Wisuhanrihanbyung (胃受寒裡寒病) of Sumin (少陰人) the author experimented various activities of mixed extract from the Sournin Kamikop'ungsan by the method prescribed in the experimental part. The results of the studies were summerized as follows: 1. Analgesic effects by acetic acid and Randall-Sellito experimental method were noted. 2. Anticonvulsive effect to strychnine was noted. 3. The sedation effects by the unbalanced effects of spontaneous momentum by wheel cage method, muscle relaxing action by Rotor rod method were noted. 4. A prolongation of anesthetic time by Thiopental-Na on the mice was noed. 5. The expansion of blood vessels by relaxation of smooth muscle was noted. According to the above results, results of Soumin Kamikop'ungsan on oriental medical references were consistent with the actual experimental results.

  • 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.

  • The effects of the water extract of 'Banhahubagtang', the combined herbal medicine, on the low esophageal sphincter, stomach, small intestine and CNS were investigated, and the results were as follows: The hexobarbital induced sleeping time was prolonged in female mice. The convulsion induced by electric shock was suppressed and analgesic action was recognized in mice. The extract inhibited intestinal propulsion of barium sulfate in mice. The extract inhibited free acid secretion and showed remarkable suppression of gastric ulcer in rats. Relaxation induced by isoproterenol and norepinephrine in low esophageal sphincter(L.E.S.) of rabbit was potentiated by addition of the extract. In conclusion, the Banhahubagtang exhibited anticonvulsive, sedative and L.E.S. inhibitory activities. These experimental results might indicate to be coincided with the indications for neuro-esophago-stenosis, esophagitis, esophagia, gastralgia, and neurosis which are well referred to the literature of oriental medicine.

  • The recombinant gamma-interferon (LBD-001) which was produced by yeast as host system was investigated on the pharmacological activities. This gamma-interferon exhibited potent inhibitory effect on adjuvant induced arthritis, but no effect on carrageenin induced paw edema in rats. It did not show any sedative, anticonvulsive, analgesic and hypothermic activities in animals. It also had no influences on isolated tracheal muscle and ileum of guinea pig, isolated uterus and fundus strip of rats, and on blood pressure and respiration in situ experiments of rabbits.
