In vitro.MAO‐A activity was inhibited 16‐25%, and MAO‐B activity was inhibited 20‐50% by SE treatment (12.5, 25 and 50 μg), In vivo.male C57BL/6 mice Received intraperitoneal injection of SE (20 mg/kg/day) for 14 days. The results showed that MAO‐A activity of pre‐SE‐treatment mice brain was inhibited in whole brain, cerebral cortex, substantia nigra. MAO‐B activity of pre‐SE‐treatment mice brain was inhibited in substantia nigra and cerebellum than saline‐treated control group. These results suggest that SE inhibits MAO activity in vivo.which would be expected to results in anti‐depressive and neuroprotective effects. 相似文献

The seasonal prevalence of the Culex pipiens group larvae occurring in a puddle in the basement of an apartment building was investigated from June 1993 to May 1994 (Period I), and from June 1994 to May 1995 (Period II). Totals of 25 237 individuals in Period I and 4989 individuals in Period II were collected: they were all C. pipiens group larvae, most of which were C. pipiens molestus. In Period I, the larvae occurred at a relatively low density in the hot months July and August; density began to increase from the cooler late September, peaked in late November, and was maintained at a high level until the third week of December. In Period II, in which mean air temperature was 5°C higher as of July and August than in Period I, larvae sharply decreased in number by one‐fifth of the total volume in Period I, and showed a peak density in the third week of July, and the peak continued until mid‐December. In Period I, the low temperature was favorable for oviposition activity of C. pipiens molestus, and accounts for the higher density of larvae in Period I than in Period II. C. pipiens molestus mostly stopped laying eggs between early December and late January. Larvae were not collected in March and April 1994 and in April 1995. However, considering that adult mosquitoes had been collected throughout the two periods except in March 1994, adults of C. pipiens molestus are thought to appear throughout the year. 相似文献

Spiladarcha adamskii sp. nov. is described from Venezuela and is compared to S. derelicta, the type species of the genus. Spiladarcha is characterized by the features of male genitalia, which have not been known previously for the genus. Spiladarcha are distinguished from its sister genus Wockia in having raised scales of small black spots along the upper surface of the forewing veins, a pair of setal zones on the apical part of the tegumen in the male genitalia, and a linguiform antrum and a zone of longitudinal pleats on the ductus bursae in the female genitalia. 相似文献
