Correlation of Ki-67, p53, and Adnab-9 immunohistochemical staining and ploidy with clinical and histopathologic features of severely dysplastic colorectal adenomas.

Variations of Ki-67, p53, and Adnab-9 monoclonal antibody reactions in colonic adenomas may be associated with colonic cancer risk. We studied the predictive value of these markers for adverse behavior in severely dysplastic colorectal adenomas, such as an associated carcinoma, multiplicity of adenomas, and subsequent development of adenomas. For this purpose we compared theclinical, gross, and histologic characteristics of highly dysplastic index polyps in 42 patients with Ki 67, p53, and Adnab-9 immunostaining and other molecular markers.

Effect of insulin-like growth factor type I on critical size calvarial bone defects in irradiated rats.

Irradiated wounds are characterized by a slow healing process. Insulin-like growth factor-1 (IGF-1), a somatomedin C, has been shown in previous studies to stimulate collagen synthesis and bony repair. The purpose of this investigation is to evaluate the potential beneficial effects of recombinant IGF-1 in the healing of critical size calvarial defects in previously irradiated adult male Sprague-Dawley rats.
