The psycho-pharmacological effect of BRHAT VATACHINTAMANI RASA (BVC) an Ayurvedic preparation was investigated, both in animal and clinical models. It was observed that BVC possess a sedative or quitening effect in that it significantly decreased the spontaneous motor activity, and also lowered the exploratory behavior of the amphetamine treated animals. This was further evident by increase in climbing out time and taming effect on animal in isolation induced aggression test. Apart from very high dose it seems have little effect on pentobarbital sleeping time and narcotic analgesic test. The drug BVC increases performance of the animal in forced locomotor test. The effect of VATACHINTAMANI RASA on clinical study was not significant.

Among many kinds of odors, some are known to have effects of sedation or stimulation on brain activity. In this study, brain activity levels affected by four kinds of fragrance0lemon, lavender, jasmine, and rose-were tested using EEG recording. In the first experiment, the quality of alpha wave was examined under controlled rest condition. In the second experiment, the event-related potential (ERP) and contingent negative variation (CNV) were investigated during a simple reaction tasks (SRT) against auditory signal. EEG data obtained for the rest condition were analyzed suing "3-Dimensional Viewer)" which was developed by ourselves to show the chaotic attractor of the signal. Power spectrum were also calculated using FET. EEG data obtained during the SRT were analyzed by comparing CNV amplitudes about each odor condition. Results confirmed the sedative effect of the lemon and the lavender, and the stimulative effect of the jasmine and the rose.

The methanolic extract of the Rhizome of Curcuma zedoaria exhibited a significant prolongation of hexobarbital (HB)-induced hypnosis. Through liquid chromatography of an ether soluble fraction. monitoring by bioassay, three sequiterpenes, germacrone (A), curzerenone (B) and germacrone epoxide (C) were isolated as active consituents. A single treatment (100-200 mg/kg, i.p.) of each compound showed not only a significant prolongation of HB-induced sleeping time but also a significant inhibition of aminopyrine N-demethylase activity in mice, and further exhibited a typical type I binding spectra with oxidized rat hepatic cytochrome P-450 induced by phenobarbital. All of the compounds provoked a sleep episode at a subhypnotic dose of HB, implying that they possess CNS depressant properties.

From the root of Angelica decursiva-albiflora Yook, which has been used as a folk medicine for a sedative, analgesic and expectorant, four free coumarins, e.g., decursidin(I), decursin(II), umbelliferone(III) and nodakenetin(IV), and two coumarin glycosides, e.g., nodakenin(V) and decuroside I(VI) were isolate. The cytotoxicity of nodakenin(V) against L-1210 leukemia cells was less effective than cisplatin, but in the nephrotoxicity against rabbit kidney proximal tubular cell nodakenin(V) showed remarkably less nephrotoxicant than cisplatin.

Scolopendra corpus has been used as anticonvulsants and antispasmodics in the oriental medicine. It was previously shown that water extract of Scolopendra corpus had an inhibitory action on ileum in mouse. To investigate the anticonvulsant and antispasmodic activity of Scolopendra corpus, pharmacological studies have been carried out with the water extract of Scolopendra subspinipes mutilans $L.\;K_{OCH}$, which is widely distributed in Korea. 1. The extract depressed convulsions induced by picrotoxin and strychnine. 2. Sedative and antipyretic analgesic action were observed. 3. In mouse and rabbit, tone of intestinal smooth muscle was suppressed with the treatment of the extract and intestinal contraction induced by $BaCl_2$ was also inhibited, suggesting that the extract has a papaverine-like effect. Whereas, in guinea pig, intestinal and tracheal smooth muscle were stimulated, and the effect was antagonized by pre-and after-treatment of diphenhydramine, suggesting that the extract has a histamine-like effect. 4.Flow rate was increased when hind-limb of Toad was perfused with saline containing the extract, but returned to normal within 10 min. Hypotensive effect was observed in rabbit and the effect was abolished by vagotomy.

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.

The demand for drug-induced sedation for magnetic resonance imaging (MRI) scans have substantially increased in response to increases in MRI utilization and growing interest in anxiety in children. Understanding the pharmacologic options for deep sedation and general anesthesia in an MRI environment is essential to achieve immobility for the successful completion of the procedure and ensure rapid and safe discharge of children undergoing ambulatory MRI. For painless diagnostic MRI, a single sedative/anesthetic agent without analgesia is safer than a combination of multiple sedatives. The traditional drugs, such as chloral hydrate, pentobarbital, midazolam, and ketamine, are still used due to the ease of administration despite low sedation success rate, prolonged recovery, and significant adverse events. Currently, dexmedetomidine, with respiratory drive preservation, and propofol, with high effectiveness and rapid recovery, are preferred for children undergoing ambulatory MRI. General anesthesia using propofol or sevoflurane can also provide predictable rapid time to readiness and scan times in infants or children with comorbidities. The selection of appropriate drugs as well as sufficient monitoring equipment are vital for effective and safe sedation and anesthesia for ambulatory pediatric MRI.

Spasticity is a common impairment in patients with central nervous system disease. Clinical observation has demonstrated that spasticity can be aggravated by various factors such as emotional state as well as noxious stimuli. A 51-year-old male patient was scheduled for arteriovenous fistula surgery. He had right hemiplegia including motor weakness and spasticity. It was decided that the surgery would be performed under an axillary brachial plexus block (BPB). He appeared nervous when blockade was terminated. The spasticity of the right shoulder increased after ipsilateral BPB. However, when we administered sedative drugs and performed interscalene BPB 2 days later, spasticity did not occur. Exacerbation of spasticity might be evoked by an anxious emotional state. Thus, it seems to be good to consider removing of anxiety and using an appropriate approach when it is tried to perform nerve blocks in individuals with spasticity.
