Studies were undertaken to develop for the anti-inflammatory analgesic activities of 'Insam-Tang' extract, which composed of four crude drugs; Ginseng Radix, Glycyrrhizae Radix, Atractylodis Rhizoma, and Zingiberis Rhizoma, was known to be applied in edema, convulsion, excremental blood, and cooling pain etc, in oriental herb remedies. It was exhibited significant anti-inflammatory effect on carrageenin inflammation, and preventive and therapeutic effects to chronic inflammation on Freund' complete adjuvant in rats, Especially, therapeutic effect of extract 500mg/kg was observed more effective than that of phenylbutazone 50mg/kg. Also, it was shown significant effect on leakage of dye into the peritoneal cavity and analgesic effect on squirm symptom induced by acetic acid in mice.

The single oral toxicity of Jeju citrus rind pectin (Jeju pectin) was studied in Spraque-Dawley rats of both sexes. In this study, rats were administrated orally with dosages of 100, 250 and 500 mg/kg of Jeju pectin. We daily examined number of deaths, clinical signs, body weights and gross findings for 14 days after Jeju pectin administration. When we administered different doses of 100, 250 and 500 mg/kg. We found no rats died in both sex after administration. Some clinical signs (decrease locomotor activity, salivation, soft stool, prone position, lacrimation, crouching position, convulsion, ataxic gait, incontinence of mine) were also observed during the experimental period.

Carbon dioxide is the fourth most abundant gas in the earth's atmosphere, and it is widely used in the chemical industry. Solid carbon dioxide is commonly known as dry ice. At low concentration, carbon dioxide appears to have little toxicological effect. At higher concentrations, however, it can produce an increased respiratory rate, tachycardia, cardiac arrhythmia, loss of consciousness, convulsion, and even death. Management of carbon dioxide poisoning requires the immediate removal of an individual from the toxic environment and administration of oxygen. It is important to know the concentration of carbon dioxide to which a patient has been exposed. We report a case of acute poisoning from solid carbon dioxide in a patient presenting with drowsiness and diminished mental capacity when she arrived in the emergency department. She recovered completely after administration of oxygen with conservative treatment.

The Chinese crude drug, 'Yong Dam (龍膽)' which is derived from the root of Gentiana plants of the family Gentianaceae, has been used as remedy for stomachic, intestinal catarrh, convulsion, etc. With regard to the botanical origin of 'Yong Dam', it has been considered to be Gentiana species of Gentianaceae, especially Gentiana scabra, but there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Yong Dam' from Korea, we studied on the anatomical characteristics of Gentiana species growing wild in Korea i.e. Gentiana scabra var. buergeri, G. uchiyamai, G. triflora, G. axillariflora var. coreana and of 'Yong Dam' from Korea on Korean market. Through our studies, the botanical origin of 'Yong Dam' from Korea was proved to be Gentiana scabra var. buergeri and Gentiana axillariflora var. coreana.

Stellate ganglion block(SGB) is frequently performed to relieve a patient from headache of various. We experienced a rare case of subarachnoid hemorrhage by aneurysmal rupture after SGB. A 46-year-old female patient diagnosed with tension headache, and normal MRI finding consulted our pain clinic. We performed right SGB in combination with greater occipital nerve block. The next day, we performed left SGB with 6 ml of 0.25% bupivacaine. She had no evidence of subarachnoid block or intravascular injection. 15 minutes after injection, she abruptly developed convulsion and loss of consciousness. She was given artificial respiration with oxygen. The diagnosis of ruptured left posterior communicating aneurysm was confirmed by 4-vessels angiography.

Objective : The purpose of these research was to investigate effects of water extract of Bistortae Rhizoma(BRE) on the hemostasia, anti-inflammatory action and central nervous system. Methods : we used mice and rats administered with the extract of the above herbs. Results : BRE decreased the permeability of evans blue into peritoneal cavity and cotton pellet granuloma formation. BRE did not decrease the acetic acid induced writhing syndrome and the histamine induced mouse paw edema. BRE inhibited the pentylenetetrazole and the strychnine induced convulsion. BRE shortened the bleeding time and plasma prtrombin time. BRE did not affect on the proliferation of Balb/c 3T3 cells. Conclusions : these results suggest that the effects of BRE are the hemostasia, anti-inflammatory action, and mild depressant activity of central nervous system.

To elucidate the activities of Uncaria Ramulus et Uncus, which has been used as anticonvulsant and antihypertensive in oriental region, the methanolic extract and its fractions were applied to inhibition of convulsion onset. The ethyl acetate fraction showed dose-dependent inhibitory activity against pentylenetetrazole-induced seizure.

The present study was designed to evaluate central inhibitory effects of an essential oil from Acori graminei Rhizoma (AGR), the dry rhizomes of Acorus gramineus Solander (Araceae) upon fragrance inhalation (aroma therapy). Preinhalation of an essential oil of AGR markedly delayed the appearance of pentylenetetrazole-induced convulsion. Furthermore, the inhalation of an essential oil of AGR impressively inhibited the activity of ${\gamma}$-aminobutyric acid (GABA) transaminase, a degradating enzyme for GABA as inhalation period is lengthened.

The neuroprotective effect of solvent fraction of native edible plant MK-104 in the mice administered with kainate was evaluated using behavioral sign, neuronal injuries and biomarkers of oxidative stress. Mice, ICR male, were administered with the BFME through a gavage for 4 days consecutively, and on the 3rd day, kainate (450 mg/kg) was i.p. administered. The fraction(400 mg/kg) delayed the onset time of neurobehavioral change (p<0.01), reduced the severity of convulsion and lethality (p<0.05), and restored the level of GSH and lipid peroxidation in brain to control value. A similar protective action was also expressed by fraction-I (200 mg/kg), which showed a prominent protection against the neuronal damage in hippocampal CA1 and CA2 regions (p<0.01) caused by kainate injection. of TBARS value. Based on these results, BFME-I is suggested to contain a functional agent to prevent against oxidative stress in the brain of mice.

The single oral toxicity of JG-381 was studied in Sprague-Dawley rats of both sexes. In this study, rats were administrated orally with dosages of 267, 400, 600, 900 and 1350 mg/kg of JG-381. We daily examined number of deaths, clinical signs, body weights and gross findings for 14 days after JG-381 administration. When we administered different doses of 267, 400, 600, 900 and 1350 mg/kg, we found 1, 4, 4, 5 and 5 male rats died and 3, 5, 4, 5 and 5 female rats died within 1 day after administration, respectively. Some clinical signs (decrease locomotor activity, salivation, soft stool, prone position, lacrimation, crouching position, convulsion, ataxic gait, incontinence of urine) were also observed during the experimental period. Our findings suggest that oral L $D_{50s}$ (95% confidence limit) for male and female rats are 327 mg/kg (270~396 mg/kg) and 250 mg/kg (256~264 mg/kg), respectively.y.
