Baicalin은 Scutellaria baicalensis에서 분리되는 flavonoid의 일종으로, 다양한 생물학적 활성을 나타내는 물질로 알려져 있다. Baicalin은 항균, 항염증, 진통작용을 나타내며, nuclear factor-kappaB의 활성을 억제한다고 보고되었다. 최근에 다양한 flavonoid 들이 골조직 대사에 관여함이 밝혀졌으며, 본 연구에서는 baicalin이 골조직의 주요세포인 조골세포의 생성 및 활성에 미치는 영향을 관찰하기 위하여, 세포증식율, 세포생존율, 염기성 인산분해효소 활성 및 osteoprotegerin 생성량의 변화를 관찰하였다. 그 결과 baicalin은 조골세포의 세포 증식과 생존율에는 영향을 미치지 못하였으나, 염기성 인산분해효소의 활성과 osteoprotegerin의 생성량을 증가시켰다. 따라서 baicalin은 골조직에서 조절물질로 역할을 할 것으로 예견된다.

The stem of Lindera obtusiloba (Lauraceae), has been widely used as a traditional medicine for the treatment of abdominal pain, bruise and hepatocirrhosis. In the present study, antinociceptive and sedative properties of the methanol extract of L. obtusiloba (MLO) were evaluated. MLO demonstrated strong and dose-dependent antinociceptive activities on various experimental pain models including thermal nociception and chemical nociception, compared to tramadol and indomethacin, reference drugs. In combination test using naloxone, the diminished analgesic activity of MLO was observed, indicating the relation with opioid receptor. Moreover, MLO also decreases pentobarbital-induced sleep latency and increases sleeping time suggesting its hypnotic and sedative action. The present results indicate that MLO could be used as valuable antinociceptive and sedative agent for the treatment of various diseases.

The analgesic effect of morphine was antagonized in mice pretreated with ginseng total saponin intraperitoneally, intracerebrally and intrathecally. The antagonized effects of morphine analgesia were reversed predominantly by treatment with L-3, 4-dihydroxyphenylalanine in the tail pinch test and 5-hydroxytryptophan in the tail flick test respectively. These indicate that the antagonistic action of ginseng total saponin might be due to their inhibitions of the activation of descending ihibitory systems at the cerebral site as well as spinal. In addition, any appreciable changes of brain biogenic monoamine levels were not observed in mice pretreated with ginseng total saponin at various time intervals. These results obtained suggest that a newly equilibrated state of neurologic function could be found in mice pretreated with ginseng total saponin, and modification of neurologic function in the mechanism for the antagonism of morphine analgesia by ginseng total saponin was more important than the changes of brain biogenic monoamine levels.

Background: The aim of this study was to compare the effectiveness and duration of action of two concentrations of bupivacaine with adrenaline for postoperative pain in patients undergoing surgical removal of four third molars under general anesthesia. Methods: Sixty patients undergoing surgical removal of four wisdom teeth received bupivacaine 0.5% (n = 30) or 0.25% (n = 30). The severity of pain in the immediate recovery period and at 2 and 24 h after surgery was recorded using the visual analogue scale. Differences were assessed by box and whisper plot and the Student's t-test. Results: The analgesic effects of the 0.25% and 0.5% doses were significantly different (P = 0.022) at 30 min after surgery but not after 2 and 24 h. The difference of mean of 0.25% and 0.5% was much higher after 0.5 h but less after 2 and 24 h. Conclusions: Bupivacaine 0.5% was statistically better for pain control during the immediate postoperative period, but there was no significant difference in pain control between the two dose strengths at 2 and 24 h after surgery.

Effect of clonidine on the dorsal horn cell responses to mechanical stimulations were studies in 3 spinalized cats and 10 cats with intact spinal cord. The type of dorsal horn cells was determined according to their response patterns to four graded mechanical stimulations (brush, pressure, pinch and squeeze) applied to the respective receptive fields. In the present study the results obtained only from the wide dynamic range (WDR) cells were included. The responses of the WDR cells to noxious mechanical stimuli were selectively suppressed following intravenous administration of clonidine into the experimental animals. The clonidine-induced changes in responses of the WDR cells to mechanical stimulation were not affected by naloxone or propranolol whereas effect of clonidine on WDR cell responses was almost completely abolished after intravenous administration of yohimbine. Also in the spinalized cats results parallel to those observed in cats with intact spinal cord were obtained. The results of present study strongly implies that analgesic action of clonidine can be mediated through excitation of ${\alpha}_{2}-adrenoceptor$ even at the spinal cord level without supraspinal mechanism.

The general pharmacological properties of YJA20379-1 2-dimethylamino-4,5-dihydrothiazolo[4,5:3,4]pyridol[1,2-a]benzoimidazole, a novel proton pump inhibitor with antiulcer activities were investigated in mice, rats, guinea pigs and rabbits. YJA20379-2 at oral doses of 50, 100 and 200 mg/kg did not affect the general behaviour, hexobarbital hypnosis and motor coordination in mice. The drug did not have analgesic or anticonvulsant action at 200 mg/kg. Locomotor activity and body temperature were not influenced at 100 mg/kg. At a concentration up to 2{\times}10^{-4} g/ml$, YJA20379-2 did not produce any contraction or relaxation of isolated preparations, such as the rat fundus, the guinea pig ileum and the rat uterus, and did not antagonize the contractile response to several spasmogens, such as histamine, acetylcholine, serotonin and oxytocin. At dosages up to 200 mg/kg p.o. YJA20379-2 did not affect the pupil size of mice. Intestinal propulsion of mice was not affected up to 200 mg/kg p.o. and the drug did not affect urinary excretion at 100 mg/kg p.o. These results indicate that at dosages up to 100 gm/kg p.o. YJA20379-2 was found not to affect this pharmacological profile. However, at 200 mg/kg the drug lowered body temperature and showed decreased in locomotor activity and urine volume.

Etomidoline ($Nonspa^{\circledR}$), which is chemically related to tertiary amine, is new synthetic antispasmodic agent with analgesic action. Antispasmodic effect of this agent is stronger than hyoscine butylbromide ($Buscopan^{\circledR}$), quaternary amine, and the absorption from intestine is also much higher. This study was undertaken to determine the effect of etomidoline on duodenal motility and other smooth muscles of rabbit. Strips of various isolated smooth muscle, 2 cm long from adult rabbits weighting about 2 kg, were suspended in a muscle chamber containing Tyrode's solution, which was bubbled with oxygen gas, and the temperature of the solution was kept constant at $38^{\circ}C$. After being washed with fresh solution several times the strips of smooth muscle attained constant motility and tonus. Etomidoline and other drugs were added in various concentrations to the chamber. Contractility of the strips was measured by using polygraph (Grass, model 7). The results are as follows: 1) In isolated rabbit atrium etomidoline produces a slight depression of contractility and the rate is also decreased. 2) On the other hand, etomidoline relaxed isolated strips of stomach, duodenal, and detrusor of rabbit. This relaxing effect of etomidoline on isolated duodenal strip of rabbit was not blocked by ${\alpha}$-adrenergic blocking agent, phenoxybenzamine, but by ${\beta}$-adrenergic blocking agent, propranolol. 3) Etomidoline did not exert any effect on isolated aorta, gall bladder, and trigone of rabbit. From the above results, it may be concluded that the relaxing effect of etomidoline on duodenal strip is related ${\beta}$-adrenergic receptor.
