Pre- and postnatal developmental changes of adrenoceptor subtypes in rat brain.

abstract：:Cell and tissue concentrations of NO2- and NO3- are important indicators of nitric oxide synthase activity and crucial in the regulation of many metabolic functions, as well as in nonenzymatic nitric oxide release. We adapted the capillary electrophoresis technique to quantify NO2- and NO3- levels in single identified...
