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.

Aspirin has been widely used as analgesic and anti-inflammatory drug. Recently, it was elucidated that aspirin have anti-coaggregatory effect in low dose. This study was carried out to investigate the synthesis of aspirin derivatives from aspirin and aromatic compound of antioxidant and its biological activities. Synthesis of aspirin derivatives was prepared by esterification in the presence of 1, 1-carbonyldiimidazole. Biological activities was examined using effect of anti-coagulant on bleeding time, effect of antioxidant and effect of anti-platelet aggregation. As a result, SJ-101 showed strong antioxidative activity and anti-coagulant activity among four compounds. Anti-platelet aggregation of SJ-101 was examined by collagen, ADP, PAF method. SJ-101 exhibited more stronger activity to aspirin at collagen aggregation reaction. These finding demonstrates that SJ-101 is usefull as care drug of aging and old-disease because of its has antioxidant activity, anti-coagulant activity and anti-platelet activity.

Propolid (bee-glue), known as a folk medicine, is a lipo;hilic material found in honeybee hives. In the present study on the anti-inflammatory effect of Korean propolis, it was extracted with ethanol, and used as a test material. The $LD_{50}$ value with the oral administration of ethanolic extract of Korean propolis (EEKP) was higher than 2g/kg in mice. The oral administration of the propolis extract (100mg/kg) significantly inhibited the development of hind paw edema induced by carrageenin in rats. the oral pretreatment of the propolis extract markedly inhibited the increase in vascular permeability and the number of writhing induced by acetic acetic acid in mice. Propolis extract, 50 and 100 mg/kg p.o. per day for 7 days, produced a significant inhibitory effect on granuloma and exudate formation in rats. This inhibitory effect was enhanced with the concomitant use of prednisolone (2.5 mg/kg). These results suggest that Korean propolis apparently has a strong anti-inflammatory activity.

Objectives : Effects of repetitive electroacupuncture(EA) on the pain behavior and activation of spinal glial cells were examined in the rat model of neuropathic pain. Methods : Twenty one adult male Sprague-Dawley rats were randomly assigned into 3 groups(control group, SP6 group, ST36+GB34 group). Neuropathic pain was induced by tight ligation of L5 spinal nerve. Mechanical and thermal hypersensitivity of hind paw were tested. Immunohistochemistry was performed in spinal cord L5/6 of all groups. EA was treated once in a day from the $5^{th}$ day after surgery. Results : EA treatments applied to ST36 and GB34 reduced significantly both of mechanical and thermal hypersensitivity after 3 times of treatment throughout the experiments. In the SP6 group, the analgesic effect was also shown after 7 times of treatment. Immunohistochemistry demonstrated inhibition of microglia and astrocyte activation in the spinal cord L5/6 dorsal horn in the ST36+GB34 group. Conclusions : The present results suggest that repetitive EA exert strong analgesic effect on neuropathic pain. These analgesic effects in neuropathic pain are associated with suppressing the activation of microglia and astrocyte.

Background: The advances in surgical technology, anesthesia and perioperative care have made it possible to perform laparoscopic cholecystectomy on an outpatient basis. This study was conducted to assess the analgesic effect and the adverse events of different dosing methods when using transdermal fentanyl patches (TDFPs) after laparoscopic cholecystectomy. Methods: Sixty patients who were to undergo laparoscopic cholecystectomy under general anesthesia were divided into two groups. Group 1: 2 TDFPs that released $12{\mu}g/h$ were applied after the induction of anesthesia and these 2 patches were removed after 24 hours. Group 2: 2 TDFPs that released $12{\mu}g/h$ were applied after the induction of anesthesia and one patch was removed after 7 hours and the other patch was removed after 24 hours. The intensity of the postoperative pain was assessed by using a visual analogue scale (VAS) and assessing the adverse events, including dizziness, pruritus and nausea/vomiting, were recorded for 48 hours postoperatively. Results: The VAS score of postoperative pain was not significantly different between the two groups at all times. The incidence of dizziness in groups I and II was 10 and 3, respectively, and the incidence of nausea/vomiting in group I and II was 4 and 0, respectively. The incidences of dizziness and nausea/vomiting in group II were significantly lower than those of group I (P<0.05). Conclusions: A dosing method that removes half of the TDFPs ($24{\mu}g/h$) after 7 hours of application caused a lower incidence of dizziness and nausea/vomiting without any significant difference of postoperative analgesic efficacy, as compared to leaving on both the TDFPs (24$\mu$g/h) for 24 hours after laparoscopic cholecystectomy.

The ethanol extracts of Puerariae Radix inhibited cyclooxygenase-2 (COX-2) activity in bone marrow derived mast cells (BMMC). COX-2 is responsible for the production of large amounts of proinflammatory prostaglandins (PGs) at the inflammatory site. We have investigated the anti-inflammatory effect of ethyl acetate fraction from $70\%$ ethanol extract of Puerariae Radix (EPR), and attempted acetic acid induced writhing to verify the analgesic effect. Inflammation was induced by interleukin-1 (IL-1), tumor necrosis factor-a (TNF-a), $inteferon-\gamma$ $(IFN-\gamma)$ and lipopolysaccharide (LPS). EPR showed strong inhibitory efficacy against cytokine-induced proteoglycan degradation, prostaglandin $E_2\;(PGE_2)$ production, nitric oxide (NO) production, and matrix-metalloproteinases (MMPs) expression in mouse macrophage and rabbit articular chondrocyte. In the writhing test, EPR $(200\~400\;mg/kg)$ exhibited a dose-dependent inhibition of writhing. The results indicate that EPR have anti-inflammatory and analgesic activities, and could be a good herbal medicine candidate for treating of osteoarthritis (OA).

Morphine, a $\mu$-receptor agonist, produces strong analgesic effect with some side effects such as nausea, vomiting, urinary retension, somnolence, and respiratory depression. Buprenorphine also provides strong analgesic effects, and hemodynamic changes after continuous infusion of morphine, or buprenorphine-ketorolac combination in gynecologic patients. Analgesic effect was assessed by visual analogue scale(VAS) and Prince Henry scale(PHS). Morphine group, initial 2 mg of bolus morphine was followed by 48 mg/96 ml of continuous infusion. Buprenorphine group, initial 0.1 mg of buprenorphine was followed up with infusion by 2.3 mg/100 ml. Half dose of both initial bolus and maintenance buprenorphine with ketorolac 15 mg for bolus and 60 mg for maintenance were infused in buprenorphine-ketorolac combination group. No significant hemodynamic changes were seen in any of the groups. VAS significantly decreased after 15 minutes of infusion in all three groups, and was significantly lower in morphine group than the other 2 groups, after 60 minutes. PHS was decreased significantly 15 minutes after infusion in the morphine group, and after 60 minutes in two other groups. The incidence of side effects were similar between morphine and buprenorphine groups, but significantly reduced in buprenorphine-ketorolac combination group. We concluded that buprenorphine could be an alternative to morphine for postoperative pain, and smaller dose of buprenorphine could be used if it is combined with ketorolac with less side effects.
