Perfect state of Microsporum gypseum complex isolated from animals and soils.
1988
Lee H.J. | Choi W.P.
Mating experiments were performed to elucidate the distribution of perfect state of Microsporum gypseum complex originating from animals and soils in Korea. A total of 30 strains of M. gypseum complex, composed of 16 from animals and 14 from soils, mated with the tester strains of Nannizzia incurvata, N. gypsea and N. fulva. Among 30 strains of M. gypseum complex examined, 16 strains (53.3%) were N. incurvata, 13 strains (43.3%) N. gypsea and 1 strain (3.3%) N. fulva. Among 13 strains of dog isolates, 8 strains (61.5%) were N. incurvata and 5 strains (38.5%) N. gypsea. And each strain isolated from Korean native goat, monkey and albino rat was N. gypsea. Among 14 strains of soil isolates, 8 strains (57.2%) were N. incurvata, 5 strains (35.7%) N. gypsea and 1 strain (7.2%) N. fulva. And - mating type was more frequently obseved than + mating type in the strains of N. incurvata and N. gypsea. By this study, N. fulva was isolated the first time in Korea.

This study has been carried out to investigate the augmenting or inhibiting effects of histamine, 5-hydroxytryptamine and their antagonists on the uterine motility. The uterine motility was represented by the magnitude of impulse and the frequency of uterine contraction which was counted by the number of waves on the recording paper. The inhibitory effect of phenoxybenzamine on the response to 5-hydroxytryptamine is the result of drug antagonism. Histamine stimlates or inhibits the motility of smooth muscle through H1 or H2-receptor. The uterine motility was increased through H1-receptor. Histamine induced relaxation by acting through H2-receptor.
