r-type calcium channels
Examples
- Vascular and biological characteristics of amlodipine beyond l - type calcium antagonist
型钙通道阻滞作用以外的血管生物学特性 - With holding potential of - - 80 mv depolarization beyond - - 50 mv elicited an inward current , peaked at + l0mv and reversed between + 40 mv and + 60 mv 5 ll m nicardipine , a potent blocker of l - type calcium channel , markedly blocked the " ib
开始出现，峰值在去极化刺激至10 20mv出现，翻转电位为巧0仍0mv 。 l型钙通道特异性阻断剂nicadipine可以明显抑制ib 。 ，并且iv曲线分布在应用nicardipine前后无改受。 - ( 2 ) in high ca2 + krebs - henseleit ( k - h ) solution ( twice of normal concentration ) , duration of phasic contraction induced by fac was prolonged , which was longer than 60min , and the contractile amplitude was enhanced to 58 . 71 ? . 71 % ( p < 0 . 01 ) . after rings were incubated with nifedipine for 15min in order to block the l - type ca2 + channel , the iron induced contractile amplitude was inhibited
主动脉环用硝苯毗咤（ nifedpine ， nif ）孵育15min以阻断卜型钙通道后，再给予铁刺檄，与未加nif的同浓度细胞外钙离于组相比，铁所致的收缩幅度均明显降低（均p 0刀1 ） ，且高钙液中铁引起的相位性收缩幅度明显高于正常钙组。 - 5 - ht induced local ca 2 + transients ( ca2 + sparks ) in cultured rat stomach fundus smooth muscle cells ( sfsmc ) was first observed by using the new fluorescent ca2 + indicator stdin and laser scanning confocal microscope . the mechanisms of initiation of ca2 + sparks and propagating ca2 + waves and their relation to e - c coupling were also discussed . 4 . the effects of reactive oxygen species on the spectral properties of the new fluorescent ca2 + indicator stdin were evaluated using four different oxidant - generating systems
