Abstract: To explain at molecular level the influence of GnRH at different impulse frequencies on the secretion of LH by GTH.Research the change of LHβ mRNA in cells when the pituicytes of original generation of rats cultured in vitro were stimulated by GnRH at different impulse frequencies, by applying the technique of culture in vitro of cells in combination with the fluorescent quantitation of PCR.The result showed that in the condition of the same vibration amplitude, when the cells were stimulated by impulse at high frequency (at the interval of 30 min), the level of LHβ mRNA reached the top.This supports the hypothesis that GnRH impulse frequency itself is a regulation signal,and GnRH impulse at high frequency brings about mainly the response of LHβ.
