摘要

Conclusions With the function of adjusting pHi, NHE-1 may play an important role in the proliferation and apoptosis of pulmonary artery smooth muscle cells. Objective To evaluated the roles of Na~+/H~+ exchanger-1(NHE-1)in the proliferation and apoptosis of pulmonary artery smooth muscle cells in rats. Methods Twenty Wistar rats were randomized into control group and 3-week hypoxic group. Intracellular PH(pHi)of the smooth muscle was determined with fluorescence measurement of the pH-sensitive dye BCECF-AM, and the expression of NHE-1 mRNA was detected by reverse transcription polymerase chain Reaction(RT-PCR).
