  • A taxonomic study of the Oxyporinae including a single genus Oxyporus Fabricius in Korea is presented. Members of the genus are known to be obligate inhabitants on fleshy mushrooms. They are characterized by crescent-shaped last labial palpomere. Nine species are recognized, five of which are reported for the first time in Korea (Oxyporus basicornis Cameron, O. basiventris Jarrige, O. crocatus Fauvel, O. niger Sharp, O. triangulum Sharp). The illustrations, descriptions, and key to the Korean species of the Oxyporinae are presented.

  • Fifty six mycelial cultured Basidiomycetes were screened for their inhibitory effects against prolyl endopeptidase(PEP), acetylcholine esterase(AChE) and thrombus coagulation. Out of them, methanolic extract of mycelium and/or ethylacetate(EtOAc) soluble fraction from culture broth of Peniophora quercina, Amanita aspera, Phellinus chrysoloma, Grifola frondosa, Wolfiporia extensa, Clavicorona pyxidata and Phanerochaete sordida inhibited more than 90% of PEP activity at 40 ppm. The extracts of Lenzites betulina, Phellinus chrysoloma, Wolfiporia extensa, Phanerochaete sorrlida, Hypocrea nigricans, Coriolus azureus, Flammulina velutipes, Phlebiopsis gigantea and Bondarzewia montana exhibited about 40% of inhibitory activity against AChE at 40 ppm. In thrombin times assay, the extracts of Amanita aspera, Oxyporus latemarginata, Peniophora quercina, Fomes fomenfarius, Trametes versicolor, and Phlebiopsis gigantea delayed coagulation of thrombus about two to three times over control at ca 550 ppm. In activated partial thromboplastin times assay, none of the tested Basidiomycetes showed significant effect.

  • The antibacterial activities of thirty mushroom species belonging to Basidiomycetes and Ascomycetes, cultivated on two liquid media, were evaluated against gram-positive (Bacillus subtilis and Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria by the disk diffusion method. All of the mushrooms, except Auriporia aurea, Fomes fomentarius, and Lyophyllum shimeji, showed different antibacterial activity levels—from 9.5 mm in diameter of the inhibition zone to full inhibition of growth of the test bacteria. The antibacterial activities of Crinipellis schevczenkovi, Hohenbuehelia myxotricha, Oxyporus obducens, and Spongipellis litschaueri were observed for the first time. The antibacterial potential of culture liquids of the investigated species was higher than that of their mycelia activity. Dependence of the intensity of antibacterial activity on the culture medium was shown. The antibacterial efficiency of the most active species (Lentinus edodes, Piptoporus betulinus, and Phellinus igniarius) was verified and compared with those of some commercial antibiotics and natural essential oils of Salvia and Eucalyptus. The culture liquid of Piptoporus betulinus, obtained after cultivation on glucose-peptone-yeast culture medium, is a potential substance for further creation of antibacterial products.

  • This study was carried out to classify the arthropods inhabited in pine mushroom (Tricholoma matsutake Singer). The arthropods were collected in a state forest (196 compartment, 157ha) located in Yangyang-gun, Kangwon-do. After collection the arthropods were classified in laboratory. The results obtained are summarized as follow; 1. Insects inhabited in pine mushroom are in total 19 Families of 7 Orders. Some animals in Araneina, Acarina, Nematoda and Stylommatophora were also observed, 2. The most injurious pests are Gyrophaena niponensis, Elateridae, Deosophilidae and Philomycidae (Stylommatophora). 3. The most dominant species is Gyrophaena niponensis (Staphylinidae, Coleoptera). 4. Some possible natural enemies are Oxyporus germanus, Sphedanolestes impressicollis, Phoridae, Carabidae, Pteromalidae, Eulophidae and Araneina.

  • The fungal flora of Korean wood-rotting fungi were studied for two years from March of 1990 to February of 1992. Fresh fungi were collected from national parks, local areas, and islands throughout the country.

  • Enhancement or diminution of leukocyte migration to the specific site might be important factors for the development of inflammatory diseases. To investigate the effects of non-steroidal anti-inflammatory drugs (NSAIDs) on chemotaxis of neutrophil, we obtained neutrophils by Hypaque-Ficoll step gradient centrifugation and tested the effects of seven drugs on the n-formyl-leucyl-phenylalanine (FMLP)-induced migration of neutrophil using a 48-well micro chemotaxis assembly. Oxyphenbutazone, phenylbutazone, sulindac, zomepirac, and ibuprofen suppressed the migration of neutrophil at the therapeutic concentrations, however, indomethacin showed stimulation effect. IC50s for inhibition of neutrophil migration by these drugs are less than 100uM. When drugs were preincubated with FMLP, no inhibition on migration of neutrophil was observed. These results indicated that inhibitory effects of these drugs on migration of neutrophil might be related to the receptor sites of neutrophil rather than molecular inactivation of chemoattractant (FMLP). In conclusion, we suggested that the property of inhibition effects on neutrophil migration of several NSAIDs might be another mode of pharmacological action for anti-iflammatory effect, which showed significant effects at concentrations below therapeutic levels, in addition to cyclooxygenase inhibition.

  • The protective effect of 'ischemic preconditioning (PC)' on ischemia-reperfusion injury of heart has been reported in various animal species, but without known mechanisms in detail. In an attempt to investigate the cardioprotective mechanism of PC, we examined the effects of PC on the myocardial oxidative injuries and the oxygen free radical production in the ischemia-reperfusion model of isolated Langendorff preparations of rat hearts. PC was performed with three episodes of 5 min ischemia and 5 min reperfusion before the induction of prolonged ischemia (30 min)-reperfusion(20 min). PC prevented the depression of cardiac function (left ventricular pressure x heart rate) observed in the ischemic-reperfused heart, and reduced the release of lactate dehydrogenase during the reperfusion period. On electron microscopic pictures, myocardial ultrastructures were relatively well preserved in PC hearts as compared with non-PC ischemic-reperfused hearts. In PC hearts, lipid peroxidation of myocardial tissue as estimated from malondialdehyde production was markedly reduced. PC did not affect the activity of xanthine oxidase which is a major source of oxygen radicals in the ischemic rat hearts, but the myocardial content of hypoxanthine (a substrate for xanthine oxidase) was much lower in PC hearts. It is suggested from these results that PC brings about significant myocardial protection in ischemic-reperfused heart and this effect may be related to the suppression of oxygen free radical reactions.
