查询词典 adenomas

First, the individuals who would be most likely to benefit need to be identified, writes editorialist Sanford Markowitz, MD, PhD, from Case Western Reserve University, in Cleveland, Ohio. Then, it needs to be shown that certain persons reproducibly demonstrate high COX-2 expression in independent adenomas or cancers, because of genetic predisposition or environmental exposures. And third, the work of Dr. Chan and colleagues needs to be extended by demonstrating that prevention of colon adenomas by aspirin or COX-2 inhibitors also involves blocking the development of the highest COX-2–expressing lesions, he says.

The expression of NSE was detected in cortex of adrenal cortical hyperplasia, cortical adenomas and pheochromoeyte carcinoma, hut not in that of pheochromocytoma and normal adrenal. The expression of SYN was detected in cortex of corticohyperplassia, cortical adenomas, medull neoplasm, chromophile tumor and pheochromocyte carcinoma, but not in that of cortical adenocarcinoma and normal adrenal. The expressions of CgA, NSE and SIN were detected in the medulla of all cases. Conclusion The characteristic of CgA, SYN and NSE in cortex and medulla of adrenal are useful in the differential diagnosis of tumor and hyperplasia in the adrenal.
