The transform of phenotype of VSMC: The mRNA expressions of SM22α-a notate gene of contractile VSM-were all detected on normal aortas,but decreased normally when the aortas were destroyed and cultured in vitro for 10 days,especially in the serum groups,whose SM22αmRNA could not be detected by RT-PCR.Here,BQ123 can increased their expressions.This demonstrated that serum culture and the secretion of ET-1 can produce the transform of phenotype from contractile to synthesize type.

血管平滑肌表型的转化：RT-PCR检测发现，血管平滑肌收缩表型标志基因SM22α在正常血管平滑肌中都有表达，但在内皮损伤后体外培养10天的血管表达明显减弱，其中血清培养组血管基本不表达，加内皮素受体阻断剂BQ123后，各组SM22α的表达均有所上调，这表明内皮素分泌和血清培养促进了血管平滑肌的表型由收缩型向分泌型的转化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
