ABC)immunohistochemical method was applied to locate P 53 protein in the follicles of Gekko swinhonis?Dinodon rufozonatum and Peoldiscus sinensis. The results showed that minority of Gekko swinhonis's granular cells took on P 53 positive reactivity, all the P 53 immunoreactivity was located in the cytoplasm of Dinodon rufozonatum's granular cells, and P 53 positive immunoreactivity emerged in the early follicular cells of Peoldiscus sinensis. Studies suggested that P 53 protein in t...
