  • Paecilomyces sinclairii was administered ad libitum feeding at percentage levels of 0, 1.25, 2.5, 5 and 10 percentage (calculated about 8 g/kg)/feeder for a period of 3 months. There was no observed clinical signs or deaths related to treatment in all groups tested. Therefore, the approximate lethal dose of P. sinclairii was considered to be higher than 8 g/kg in rats. Mild decreases in body weight gain were observed dose-dependently in P. sinclairii treated groups in dose response manner after 2 weeks. Interestingly, the weight of abdominal adipose tissues surrounding epididymides were greatly reduced by this Dongchunghacho, in parallel with the mild increase in body weight gain. However, the absolute weight change of other organs was not observed. There were not significantly different from the control group in urinalysis, ocular examination, hematological, serum biochemical value and histopathological examination. From these results, it is concluded that the no-observed-adverse-effect level (NOAEL) of P. sinclairii is less than 1.25% (1 g/kg) in rats in the present study.

  • Isaria sinelairii (IS) was orally administered at doses of 0, 0.04, 0.2, and 1 g/kg/day over a 13-week period. There were no observed clinical signs or deaths related to treatment in all the groups tested. Therefore, the approximate lethal oral dose of I. sinclairii was considered to be higher than 1 g/kg in rats. Throughout the administration periods, no significant changes in diet consumption, ophthalmologic findings, organ weight, clinical pathology (hematology, clinical chemistry, coagulation, and urinalysis) or gross pathology were detected. Minor changes were found in hematological parameters for the 0.04 g/kg/day and 0.2 g/kg/day IS treated groups (triglyceride reductions of $20.1{\sim}46.6%$ and platelet increases), but all changes were within physiological range. Microscopic examination failed to identify any treatment-related histopathologic changes in the organs of the IS-treated rats other than nuclear enlargement (cellular atypia) of the tubular regions in the medulla of the kidney in the high dose group. From these results, one can conclude that the no-observed effect level (NOAEL) of I. sinclairii is less than 0.04 g/kg/day in rats.

  • Many ascomycetes were collected at Mt.Unjang, Pyonsan penisula national park, Mt.Moak Chonbuk provincial park, Daea-ri hebarium and Mt.Whaam from August 1996 to October 1999. They were identified. According to the resulting, Lanzia echinophila, Discina parma, Hypomyces auranticus, Helotium versicolor, Cordyceps militaris f. albino, Isaria sinclairii are newly to Korea. They were designed Korean common names by author.

  • We prepared antibodies from insect glycosaminoglycans (GAGs) and assayed the titer. Nine polyclonal antibodies against insect GAGs were raised for development of an ELISA in biological fluids (mice serum). The 3th booster collection of antiserum of BALB/c mice as a primarily antibody was assayed for titer determination by ELISA method. In sandwich ELISA of GAGs derived from Isaria sinclairii or other insects, antiserum from insect GAGs gave satisfactory results for so potent antibody(100: 1~1000:1) raising (manufacturing) agent in range of 10 ng/ml.
