Our results indicated that the cell membrane fluidity in the model group decreased approximately 8% compared with the control group, and after brain cells were incubatied with species, the membrane fluidity could be recovered closely to the control level depending on the BYHW decoction and its different constituents. As the membrane fluidity is a very sensitive biological index which reflectsd the cell status, our method will be useful to study the molecular mechanism of tradition Chinese medicine (TCM) and its combination recipe.展开更多
A total of 236 eggs were laid by the population of the wild crested ibis ( Nipponia nippon ) in 72 nests in Yang County,Shaanxi Province,China,from 1981 to 1997,with an average of 3 3 eggs per nest.Among the eggs,169 ...A total of 236 eggs were laid by the population of the wild crested ibis ( Nipponia nippon ) in 72 nests in Yang County,Shaanxi Province,China,from 1981 to 1997,with an average of 3 3 eggs per nest.Among the eggs,169 nestlings were hatched,accounting for 71 6% of the total;and 129 young birds grew up and flew from their nests,accounting for 76.3% of all the nestlings.Since 1981,133 birds have been brought up in the county.The birds have established 27 breeding sites in the county,with the number of breeding couples increasing from 2 pairs in 1981 to 10 pairs in 1997.The birds mature at 2 years old,either male or the famele is 2 years old,The maximum age difference between the 2 sides of a couple is 2 years.展开更多
