[Expression of acid-sensing ion channels in neurons of trapezoid body and lateral paragigantocellular nuclei in rat brain, and effects of intermittent hypoxia on their expression].

Objective: To investigate the expression of three acid-sensing ion channel (ASIC) subtypes termed as ASIC1b, ASIC2a, and ASIC3 in the neurons of trapezoid body and lateral paragigantocellular nucleus of rat brainstem, and the effects of intermittent hypoxia on their expression.

Methods: The intermittent hypoxic rat model was established, of which the blood gas analysis was tested after 12 days. The immunohistochemistry SABC method was performed to test the expression of ASIC1b, ASIC2a, and ASIC3 in neurons of trapezoid body and lateral paragigantocellular nucleus in the control (O2) and intermittent hypoxic (IH) groups of rats.
