| Abstract: | In order to further understand the nerve regulation mechanism in effect of light on hen production performance,influence on the expression of c-fos gene by the different intensity light stimulation in hen tectofugal pathway was studied using nervous labeling combining with the immunohistochemistry method.The right eyes of hens in 120 day-old were shaded to keep dark for 5 d,then small amount of 30% HRP was injected into the thalamencephalon nucleus rotundus(ROT).After a 48 h survival period,light stimulation of different intensities was given for 1-1.5 h,afterwards kept in dark again for 1.5 h.Following perfusing with fixative,their brains were removed and made into continuous frozen sections.TMB method was used to show the HRP retrograde labeling nervous cells,and the immunohistochemical reaction of Fos protein was employed to detect the expression of c-fos gene in these regions.The results showed that there are different reactions to different light stimulation in the nucli of hen tectofugal pathway.Stratum griseum centrale(SGC) and ROT are most sensitive to the light of 30 lx,while the nucleus SP/IPS is more sensitive to the light of 40 lx. |
