The effects of the alcoholic extract of Bacopa monniera (BMA) on morphine-induced pharmacological activities were studied in mice. Oral administration of the extract (40 mg/kg) significantly inhibited morphine-induced analgesic tolerance, withdrawal symptoms, hyperactivity, reverse tolerance, Dopamine receptor supersensitivity and apo-morphine-induced climbing behaviour in mice. The results of this study showed that, alcoholic extract of Bacopa monniera (BMA) exerted inhibitory effect against morphine-induced pharmacological effects, suggesting that the extract could be useful in the treatment of morphine toxicity.

To investigate the effects of wearable near-infrared ray-emitting knee pads on knee pain among elderly adults in Korea. Randomized controlled trial evaluating the effects of near-infrared rays (NIR) on knee pain in Korean elderly adults. Five community-based research facilities (two welfare centers, a senior citizen center, and two churches). Forty-seven participants aged 65 years and older who had experienced knee pain. The experimental group (n = 25) wore NIR-emitting knee pads for one month at nighttime while sleeping. The control group (n = 22) wore knee pads without NIR. Demographic characteristics, intensity and duration of knee pain, amount of analgesic medication used, range of motion, gait speed, and health-related quality of life were collected using questionnaires. The experimental group showed decreased intensity (t = -6.17, p < 0.001) and duration (t = -3.34, p = 0.002) of knee pain and reduced analgesic use (t = -2.30, p = 0.026) compared to the control group. NIR may be an effective non-pharmacological option for relieving knee pain in elderly adults.

DA-5018 is a synthetic capsaicin derivative under development as a non-narcotic a analgesic ag$\varepsilon$nt. DA-50 18 showed a potent analgesic activity against acute and chronic pain m model(Tablel, 2.), but it had a narrow margin of safety. DA-5018 did not bind to opioid(${\kappa}, {\delta}, {\mu}$), NKl, CGRP receptors in vitro and its analgesic effect was not antagonized by naloxone, a and it did not develop analgesic tolerance. In addition DA-5018 had no inhibitory effects against c cyclooxygenase and 5-lipooxygenase activities. DA-5018 significantly increased the relcase of substance P from the slices of the rat spinal cord. These results suggest that DA-50 18 is not a narcotic nor aspirin-like analgesic and the release of substance P is one of analgesic mechanism of action of DA-5018. We found that DA-5018 was almost ten times more potent and was at l least IOO-times less irritable compared to capsaicin. Accordingly development of topical formula was adopted. Topical formula was desiged and screened by flux test of DA-5018 using hairless mouse skin and several formulas were selected. With these topical formulas we a assessed the analgesic efficacy and carried out the toxicity, skin irritation and pharmacokinetic studies. In streptozotocin-induced hyperalgesic rat and 50 % galactose-fed hyperalgesic rat as diabetic pain models, DA-5018 cream increased the pain thresh이ds up to 77.0% and 24.4% respectively, while Zostrix-HP(capsaicin cream) incr$\varepsilon$as cd by 65.9% and 21.0%. DA-5018 c cream showed a good analgesic effect as welI in FCA-induced arthritic rat. DA-5018 cream did not show any toxicological signs in acute and chronic toxicity test and had little skin irritation in car swclIing and scratching t$\varepsilon$st. Pharmacokinetics of DA-50 18 were studied after topical application of ${14}^C$-Iabelled or unlabelIed DA-5018 cream. Plasma and skin concentrations c except applied skin wcre below the dctection limit and after 7-day cummulative application, plasma concentrations were also below detection limit DA-50 18 may have an advantag$\varepsilon$ ov$\varepsilon$r c capsaicin and is now being developed as a topical agent for the treatment of pains. DA-50 18 cream was approved for Korean IND and is now under a Phase II clinical study for arthritic pain a after finising Phase I study. DA-50 18 was also liscensed out to Stiefel Company in America in

In order to investigate experimentally the clinical effects of Choweesungchung-Tang that has been widely used in the cardiovascular and neuropsychogenic disease, experimental studies with experimental animals were carried out. The results of these studies were summarized as follows; Suppressive action was not shown on the convulsion induced by strychnine, but significant effect was noted on the convulsion induced by picrotoxin and caffeine. In acetic acid method, analgesic effect was noted. By the rotor rod and wheel cage method, sedative action was noted. A prolongation of hypnotic time induced by pentobarbital-Na was obtained. Relaxing action was noted remarkably on the ileum of mice, also about mice and guinea-pigs, the same effect was recognized on the smooth muscle of the ileum. The expansion of blood vessels by relaxation of smooth muscle and hypotensive action were noted.

The purpose of this study was to compare postoperative analgesic effect according to intravenous doses of ketorolac. The ninety-eight adult patients, scheduled for elective surgery under general anesthesia, were randomly assigned to receive saline or one of the five doses of ketorolac (10, 15, 30, 45, 60mg). After recoverg from anesthesia, saline or ketorolac was injected intravenously, and the visual analogue score, sedation secore, mean blood pressure, heart rate, and the incidence of nausea and vomiting were measured 30 minutes, 1 hour and 2 hours the injection. Saline or 10 mg of ketorolac had no postanalgesic effect. Above 15 mg of ketorolac had analgesic effect, but this analgesic effect was not increased with increasing doses of ketorolac (30, 45, 60 mg). Any side effects (nausea, vomiting, excessive sedation, cardiopulmonary depression, and renal and hematologic adverse events) was not observed associated with ketorolac administration. These results suggested that 15 mg of ketorolac is the most reliable dose for postoperative anlgesia in intravenous administration.

In this study we fed control diet and tryptophan supplemented diets containing 0.35% tryptophan to ICR mice for 2 weeks. The concentrations of serotonin and 5-HIAA were changed by injection of the serotonin synthesis inhibitor, p-CPA and the serotonin precursor, serotoninP and the change of brain serotonin concentration negatively correlated with that of pain sensitivity, and p-CPA and serotoninP also changed the analgesic effect of morphine. The injection of naloxone, the opiate antagonist, resulted in an increase in the writhing frequency, but its antagonistic effect was not significant. The concentration of 5-HIAA elevated in mice brain at least 3hr after administration of morphine hydroxide indicates that the changes in brain serotonin metabolism may be associated with the acute effects of morphine analgesia. In short, these results not only suggest that tryptophan supplemented diet suppress pain sensitivity in mice, but also indicate that at least in part analgesic mechanism of serotonin may be associated with morphine analgesia.

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.

Loxoprofen sodium is an orally used anti-inflammatory, analgesic and antipyretic agent. For alleviation or inhibition of the pain symptoms regardless of referred or superficial pain, the prompt absorption of a drug and its immediate bioavailability might be generally required for a formulation or development of a new drug. Therefore, in intramuscular administration, its anti-inflammatory, analgesic, and antipyretic effects were evaluated compared with an oral administration in animals. The occurrence of gastric damages which is common in nonsteroidal anti-inflammatory drugs was also observed.
