  • A polysaccharide, G009, isolated from Ganoderma lucidum IY 009, was subjected to investigating on general pharmacology. This material at the large oral doses of 1000 and 2000 mg/kg in mice did not exhibit any abnormal behaviors and another effects on central nervous system. It also had no influences on hexobarbital-induced sleeping time, rotarod test and spontaneous activity test at each oral dose of 1000 mg/kg in mice. No effects on the body temperature and on acetic acid induced writhing syndrome in mice were observed with its oral administration at 1000 mg/kg, and the convulsions induced by strychnine and pentetrazole were not inhibited at its oral doses of 1000 mg/kg in mice. The solution of G009 as given intravenously at the doses of 30 and 60 mg/kg in rabbit had no influences on blood pressure and respiration rates and depth. In isolated organs of rat uterus and fundus muscles and guineapig ileum and trachea, it did not show any contraction or relaxation at the concentrations of 2$\times$10$^{-3}$ g/ml, and the contractive actions produced by oxytocin, acetylcholine, serotonin and histamine were not inhibited at the same doses. This material showed no effect on intestinal propulsion test in mice and gastric secretion in rats at the oral doses of 1000 mg/kg. However, it is interesting that the material exhibited potent inhibition of acidified aspirin induced gastric damage at the doses of 500 and 1000 mg/kg in rats.

  • Objectives: To investigate the anti-inflammatory, analgesic, anti-pyretic and anti-histamine activities of 20 herbal medicines to test their efficacy in common cold treatment. Methods: For all experiments, the herbal medicines were extracted with 80% ethanol and freeze-dried. To determine the anti-oxidative properties, we tested DPPH-free radical-scavenging activity and xanthine oxidase inhibitory activity. To determine anti-inflammatory and analgesic potential, we investigated acetic acid-induced vascular permeability and writhing test in ICR mice. For anti-pyretic activities, an LPS-induced pyrexia study was conducted in rabbits. To evaluate the anti-histamine activity, we examined compound 48/80-induced systemic anaphylaxis in ICR mice and the release of β-hexosaminidase on rat basophilic leukemia (RBL-2H3) cells. Results: Ephedrae herba, Forsythiae fructus, Cinnamomi ramulus, and Cimicifugae rhizome showed potent free-radical scavenging activities. Gentianae macrophyllae radix inhibited acetic acid-induced vascular permeability. Schizonepetae spica and Cimicifugae rhizome inhibited acetic acid. Cinnamomi ramulus and Angelicae decursivae radix inhibited LPS-induced pyrexia. Angeliace dahuricae radix and Asari radix inhibited compound 48/80. Scutellariae radix, Cinnamomi ramulus, Ephedrae herba, and Zingiberis rhizoma crudus potently inhibited the release of β-hexosaminidase. Conclusions: We examined the anti-inflammatory, analgesic, anti-pyretic and anti-histamine activities of 20 herbal medicines;We examined the anti-inflammatory, analgesic, anti-pyretic and anti-histamine activities of 20 herbal medicines Codonopsis pilosulae radix, Zingiberis rhizoma crudus, and Cinnamomi ramulus showed novel efficacy. These results suggest that some of herbal medicines may be very effective in treating common cold.

  • Experiments were undertaken to assess the antinociceptive effect of bee venom (BV) in rodent animal models. Comparison of antinociceptive efficacy between Korean BV and commercially available American BV was the primary interest of the study. Korean BV was collected using BV collector devices in which an electrical impulse is used to stimulate the worker bee (Apis mellfera L.) to sting and release venom. After collection, whole BV was evaporated until dry using the BV collector. Commercially available dried American BV was purchased from Sigma Company in USA. Korean and American sourced BVs were diluted and amounts of 6 mg/kg body weight (BW), 0.6 mg/kg BW and 0.06 mg/kg BW were tested. BV was subcutaneously injected to produce an antinociceptive effect and the antinociceptive efficacy was evaluated using a writhing test in mice and a formalin test in rats. The antinociceptive effects of the two BVs tested were similar in mice for visceral pain and showed a dose-dependent response. The antinociceptive effect of Korean BV was not significantly different compare to American BV. These results suggest that Korean BV may be used to achieve an antinociceptive effect for use in medical therapies.

  • As an effective non-pharmacological method of pain relief, hydrotherapy was widely used. And bath additive has been used for enhancing the efficacy of hydrotherapy, In the present study, as a bath additive, the analgesic activity of HAC, which composed of Corydalis turtschaninovii, Atractylodes japonica, and Harpagophytum procumbens(HAC), was investigated in the ventrolateral periaqueductal gray (VIPAG), lateral PAG (IPAG), central nuclei of amygdala (CeA), and the paraventricular nucleus of the hypothalamus (PVN) in mice, using writhing test and immunohistochemistry for c-Fos. Male C57BU6 mice weighing $25{\;}{\pm}{\;}2g$ (8 weeks of age) were used for this experiment. The animals were divided into five groups: the control group, the acetic acid treatment group, the acetic acid treatment and 0.01 g/L HAC-immersed group, the acetic acid treatment and 0.1 g/L HAC-immersed group, and the acetic acid treatment and 1.0 g/L HAC-immersed group. To induce somato-visceral pain in the experimental animals, a single intraperitoneal (i.p.) injection of acetic acid was administrated to each animal, and the animals of the control group received injections of equivalent doses of normal saline. The animals of the HAC-immersed groups were immersed the water with HAC powder at the respective doses deep enough to cover the mice body, and those of the control group and the acetic acid treatment group immersed the water without HAC powder at 10 min immediately after the acetic acid injection. Our present study has shown that the HAC reduced the acetic acid-induced abdominal constrictions and the acetic acid-Induced increase of numbers of c-Fos-positive cells in the VIPAG, IPAG, PVN, and CeA. The most potent analgesic effect appeared with the treatment of 1.0 g/L KB-immersed group. Based on our present results, it is very possible that HAC can be a potent therapeutic bath additive for alleviating pain without the fear of addiction to the drugs and side-effects associated with the prescription of multiple analgesic drugs.
