It is well documented that neuropeptide Y (NPY) is involved in the regulation of the hypothalamo-pituitary gonadal axis. In order to determine the influence of NPY on the biosynthesis of GnRH, we have studied the effects of NPY and some NPY analogs on GnRH gene expression in neurons in the male rat preoptic area (POA). The following peptides NPY, peptide YY(More)
The screening and analysis of bioactive components in traditional Chinese medicines (TCMs) is very important not only for the quality control of crude drugs but also for elucidating the therapeutic principle. In this study, a method for screening potential active components from TCMs was developed by using biomembrane extraction and high performance liquid(More)
Neuroanatomical data have clearly demonstrated the existence of synaptic contacts between neuropeptide Y (NPY) endings and tuberoinfundibular dopaminergic (TIDA) neurons in the rat arcuate nucleus. In order to determine the influence of NPY in the biosynthesis of dopamine, we have studied the effects of NPY and some NPY analogs on tyrosine hydroxylase (TH)(More)
It is well known that the adrenal medulla contains high concentrations of neuropeptide Y (NPY) where it coexists with epinephrine and norepinephrine. In order to evaluate the possible involvement of NPY in the regulation of the chromafin cells of the rat adrenal medulla, we have studied the effects of NPY and some NPY analogs on the concentrations of(More)
Crop coefficients (K c) are important for the development of irrigation schedules, but few studies on K c focus on saline soils. To propose the growth-stage-specific K c values for sunflowers in saline soils, a two-year micro-plot experiment was conducted in Yichang Experimental Station, Hetao Irrigation District. Four salinity levels including(More)
It is well documented that dehydroepiandrosterone (DHEA), an adrenal androgen, is converted into potent androgens and/or estrogens in peripheral tissues. Since sex steroids are involved in the regulation of prolactin (PRL) secretion, we have studied the effect of DHEA administration on PRL mRNA levels in both adult male and female rats. Since(More)
Increasing the total molecular weight of hemoglobin through PEG modification has been proved to be a better choice in prolonging vascular retention time. As a long, linear, hydrophilic molecular, PEG exerts significant influence on the oxygen-carrying properties of porcine hemoglobin (pHb) when attached. PEG-hemoglobins exhibit a wide range of differences(More)
