It was prevously shown that 'Kamisamhwang-Tang' had been examined for effects of the anticonvulsion, antipyretic, analgesic and sedative. To investigate the effect on cardiovascular system and antibacterial activities, pharmacological studies have been carried out with each extract. The results of this investigation were summarized as follows: 1) 'Kamisamhwang-Tang' depressed central convulsion induced by strychnine, picrotoxine and caffeine in mice. 2) Antipyretic, analgesic and sedative action were observed. 3) Hypotensive effect was observed in rabbits. 4) Antibacterial activities was observed.

The acute toxicity and sedative activity of flavonoids and saponin isolated from Zizyphus seeds have been evaluated in mice. All the compounds elicited potentiation of hexobarbital-induced hypnosis, inhibition of ladder-climbing and caffeine-induced hyperactivity. Swertisin was the most potent of all flavonoids tested. The potency of saponin in these tests was found to be higher than that of swertisin. The activities in rotarod test and electroshock seizure test, on the other hand, were relatively weak or nil. From these findings it was suggested that flavonoids and saponin from Zizyphus seeds have neuroleptic activity without anticonvulsant or muscle relaxant activity accompanied by neurological deficit.

Baikgeumhoan is well known for cure of epilepsy. In order to investigate the anticonvulsion, analgesic action and sedative effect of Baikgeumhoan pharmacological studies have been carried out with Baikgeumhoan. Baikgeumhoan is composed of two drugs; Rhizoma curcumae and Alumen. The results were as follows ; 1. Anticonvulsion effect against the convulsion induced by picrotoxin in Mice was significantly recognized. 2. Analgesic action estimated by the acetic acid stimulating meehod was shown in Mice. 3. Sedative effect was shown in Mice. Considering the above experimental results, it is suggested that the effects of Baikgeumhoan based on the Oriental medicinal references were similary consistant with actual experimental results.

In order to detect the influence of overdosed combelen on the Korean native goats, 5mg of combelen per kg of body weight were injected intramusculary. Clinical findings, electrocardiograms and some blood chemical values were determined and the results obtained were as follows: 1. After administration of 5 mg/kg dose of combelen the animals were moderately depressed and often tried to take sitting position but showed moderate response to pinching stimulation of skin. 2. Body temperature and respiratory rate were not suppressed but heart rate were accelerated during sedative stage. 3. During sedation a slight change in the QRS complex and T wave appeared but it was not significant. 4. Hemoglobin concentration showed a tendency to decrease. SGOT activities were markedly increased 24 hours after administration of combelen and BUN values were slightly lowered. Blood sugar values were markedly elevated during sedative stage.

To elucidate the effects of Onkyungtang. after oral administration of Onkyungtang water extract in mice and rats, acute toxicity. analgesic. sedative, estrogenic actions. action on isolated uterine muscle were measured. The results obtained were as follows: 1. The yield of water extract of Onkyungtang was 24.5%, minimum lethal dose was 4,000mg/kg, which rarely had the acute toxicity in mice and rats. 2. The analgesic effects of Onkyungtang by acetic acid induced writhing syndrome in mice were not remarkably observed. 3. The relaxant action of Onkyungtang on oxytocin induced contracted uterine muscle in estrogenized rats were not remarkably observed. 4. The sedative effects of Onkyungtang by hexobarbital sodium induced sleeping time in mice were remarked. 5. Administration of Onkyungtang caused remarkable increase in weight of rat's uterus.

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.

A growing number of people are concerned about their sleep. There are many people with chronic sleep disorders. Sedativehypnotics including benzodiazepine and non-benzodiazepine have been widely used in chronic insomniacs. It is widely accepted that current hypnotics are efficient in alleviating subjective symptoms of insomnia. Non-benzodiazepine hypnotics include zolpidem, zopiclone, and melatonin. These novel non-benzodiazepine hypnotics that have efficacy comparable to benzodiazepines were developed with more understanding of benzodiazepine receptor pharmacology. Their unique pharmacologic profiles may offer few significant advantages in terms of adverse effects of benzodiazepines. However, most of hypnotics including non-benzodiazepine have some of dependence, tolerance, impaired daytime function and rebound insomnia. Currently, it is accepted that combination therapy with pharmacologic and behavioral intervention is the most effective for chronic insomniacs.

A water-soluble basic extract was obtained from Zizyphi spinosi semen and tested on its sedative and psychotropic activities. In a 2.2m $\times$ 2.2m $\times$ 0.8m open-field, the effect of the extract on unlearned emotional responses of mice was determined. Intraperitoneal injection of 5mg/kg, 10mg/kg, and 20mg/kg of the extract caused to show less often the frequency of ambulation, rearing and exploration and more the frequency of lying and sleeping than that of placebo control, meprobamate and chlordiazepoxide treated groups. In a standard shuttle box, the effect of the extract on learned emotional responses was determined. Intraperitoneal injection of 10mg/kg of the extract caused to show less conditioned response, secondary conditioned response and defecation than either placebo control or pre- and post-treated sessions with the extract throughout the acquisition and extinction of conditioned avoidance response. Intraperitoneal injection of 10mg/kg of the extract showed similar sedative actions with that of 1.25mg/kg of chlorpromazine. The extract shows major tranquilizer-like effect as chlorpromazine.

The effects of various sedative cyclopeptides and peptide alkaloids from the Zizyphus species on calmodulin-dependent $Ca^{2+}$ -ATPase and phosphodiesterase were Investigated. Calmodulin-induced activation of $Ca^{2+}$-ATPase was strongly inhibited by sanjoinine-A dialdehyde (IC_{50}$, 2.3$\mu\textrm{m}$), -Ah1 (IC_{50}$, 4.0$\mu\textrm{m}$), -A (IC, 4.6$\mu\textrm{m}$), and -G2 (IC_{50}$, 7.2$\mu\textrm{m}$), while calmodulin-induced activation of phosphodiesterase was strongly inhibited by both deachuine- S10 (IC_{50}$, 4.9$\mu\textrm{m}$) and sanjoinine-D (IC_{50}$, 9.0$\mu\textrm{m}$). The inhibitory activity of the various cyclopeptides and peptide alkaloids on $Ca^{2+}$-ATPase was found to correlate well with their Sedative activity.

Sedation allows patients to maintain their airway independently and respond appropriately to physical stimulation and verbal command while maintaining a minimum depressed level of consciousness. Drugs commonly used for sedation of pediatric dental patients include a combination of chloral hydrate, hydroxyzine, and nitrous oxide-oxygen. Midazolam is a benzodiazepine and currently one of the most commonly used intravenous sedative agents. It can be easily titrated to provide a wide range of sedation, from conscious sedation to deep sedation, and exhibits a wide safety margin without severe respiratory and circulatory depression. At an appropriate dose, it also decreases patient anxiety and induces amnesia. We found that the submucosal administration of midazolam combined with chloral hydrate provided increased sedative effects and decreased the postoperative vomiting response compared with conventional chloral hydrate administration, with no significant difference in physiological responses. The depth of sedation can be titrated using this technique.
