  • Systematic pharmacological studies on powdered whole part of unossified antler obtained from Cervus nippon Temminck var. mantchuricus have been carried out in mice and rats. Powdered antler, with a single oral administration, showed a very weak acute and subacute toxicity; its MLD being >5g/kg orally in mice. On daily oral treatments of the antler for 14 days, it did not cause any significant differences in body weight gain, various organ weights and serum transaminase activities compared to those of the control rats. Powdered antler, with a single oral administration, showed a remarkable analgesic activity as evaluated by writhing syndrome and tail-pressure test, a weak CNS depressant activity as well as a weak immunopotentiating action as evaluated by carbon clearance test in mice. Powdered antler, with repeated treatments, showed a moderate antifatigue effect against immobilized stress and showed significant increases in both adrenal weight and its ascorbic acid content in rats, suggesting that the mode of antifatigue effect of antler is related to adrenal and its components.

  • Dichloromethane, ethanol, and boiling water extracts of the green seaweed Codium fragile, used as an herbal medicine and known as an invasive species over the world, were examined for anti-inflammatory, antipyretic, and analgesic activities in mice. The dichloromethane and ethanol extracts inhibited inflammatory symptoms of mouse ear edema and erythema by 74% or higher. The extracts also demonstrated inhibition of pyrexia, similar to that of acetyl salicylic acid. Eicosapentaenoic acid was isolated from the seaweed as the main active anti-inflammatory compound. These findings are consistent with various claims that the seaweed can be used as remedies for inflammation-related symptoms.

  • The cycloooxygenase enzymes catalyze the oxidative conversion of arachidonic acid into prostag1andin H$_2$Which mediates both benificial and pathological effects. The COX-1 is constitutively expressed in most tissues and in blood platelets wherease the expression of COX-2 isoform is induced in response to inflmmatory stimuli such as cyctokynes. Thus the identification of a novel COX-2 selective inhibitor should offer excellent antiinflammatory activity with minimal side effects such as gastrointestinal toxicity. Recently, a group of structurally unique and biologically active pimarane diterpenoids has been isolated from indigenous Korean medicinal plants. These new diterpenoids turned out to be potential analgesic and antiinflammatory agent due to their potent inhibitory activities of prostaglandin synthesis. We have also found that the inhibition of PGE$_2$synthesis is attributed to the potent COX inhibition by pimarane diterpenoid in arachidonic acid cascade. In conjunction with development of new analgesic and nonsteroidal antiinflammatory agent, a series of works on these diterpenoids have been extensively carried out in our laboratories. These efforts involve the structure-activity relationship of pimaradienoic acid, molecular modelings and COX inibitory activities as well as actiinflammatory effects of its structural analogues. In addition, the total syntheses of the new natural pimarane diterpenoids, their stereoisomers and other structural variants were intensively investigated.

  • Objectives: The objective of this in vivo study is to observe the analgesic effects or improvements of Gyejibokryeong-hwan aqueous extracts (GJBRHe) on the Primary dysmenorrhea (PD) in rats as compared to those of Indomethacin (IND). Methods: The rats were administered with estradiol benzoate for 10 days and oxytocin 1 hour after the last 10th administration of estradiol benzoate to make the primary dysmenorrhea rat model. Gyejibokryeong-hwan aqueous extracts 500, 250 and 125 mg/kg were orally administrated, for 10 days once a day. Then the changes on the body weights and gains during experimental periods, uterine weights and gross inspections, abdominal writhing response for analgesic activities, uterus lipid peroxidation (malondialdehyde (MDA) levels), antioxidant defense system - glutathione (GSH) contents, activities of superoxide dismutase (SOD) and catalase (CAT), Nuclear factor-κB (NF-κB) and Cyclooxygenase (COX)-2 mRNA expressions, were monitored with uterus histopathology and immunohistochemistry for tumor necrosis factor (TNF)-α and inducible nitric oxide synthase (iNOS). The results of Gyejibokryeong-hwan aqueous extracts were compared to those of Indomethacin adminstered rats. Results: As results of estradiol benzoate and oxytocin treatment, noticeable decreases of body weights and gains, uterus GSH contents, SOD and CAT activities, increases of abdominal writhing responses, uterus lipid peroxidation (MDA level), uterus weights, NF-κB and COX-2 mRNA expressions were observed with increases of TNF-α and iNOS immunolabeled cells, inflammatory cell infiltrations, congestion and enlargement of the uterus at gross and histopathological inspections. These means classic inflammatory and oxidative stress mediated primary dysmenorrhea are relatively well induced. However, these signs were favorably and dose-dependently inhibited by administration of three different dosages of Gyejibokryeong-hwan aqueous extracts, but lesser than those of Indomethacin. Conclusions: The results obtained in this study suggest that Gyejibokryeong-hwan aqueous extracts has favorable analgesic and refinement activities dose-dependently on the estradiol benzoate and oxytocin treatment-induced primary dysmenorrhea signs.

  • Leonotis nepetifolia (L.) R. Br, commonly called dagga, klip dagga, or lion's ear, has been used to effectively treat various diseases and other health problems for a long time because of its antimicrobial, anti-inflammatory, antioxidant, and analgesic activities. Several studies have attributed these biological activities to L. nepetifolia's constituent secondary metabolites, such as alkaloids, phenolics, flavonoids, tannins, steroids, glycosides, coumarins, anthocyanins, and saponins. This review aims to examine the evidence-based ethnopharmacological uses of L. nepetifolia in the treatment of bronchial asthma, diarrhea, skin diseases, malaria, burns, cancer, diabetes mellitus, and rheumatism. However, although L. nepetifolia has great potential to treat these diseases, further isolation and identification of its therapeutic phytochemical constituents are required. In addition, the performance of its extracts and phytochemicals should be thoroughly tested in preclinical and clinical trials in order to ascertain their safety and efficacy, which will prove valuable in developing new medicines.
