ABSTRACT
OBJECTIVE: A large body of evidence suggests that cyclooxygenase-2 (COX-2) is important in tumor growth and angiogenesis of gastrointestinal and other cancers. This was the study to determine the relationship between tumor vascularity and COX-2 expression in invasive cervical cancer. METHODS: We examined the expression of COX-2 and microvessel density (MVD) by immunohis- tochemical staining in 21 specimens collected from invasive cervical cancer patients. RESULTS: All specimens showed weak and strong immunoreactivity, with 52.4% strong reactivity. Microvessel count was higher (median 136) in the strong COX-2 immunoreactivity specimens than the weaks (median 90), and MVD was significantly correlated with the COX-2 immunoreactivity (P=0.002). CONCLUSION: These preliminary data indicate that overexpression of COX-2 may play an important role in carcinogenesis of cervical cancer and this could be partially attributable to modulation of angiogenesis by COX-2. COX-2 maybe a target for future research in the tumorigenesis of the invasive cervical cancer.

A perplexing developmental error is 46,XX congenital absence of vagina ( Mayer-Rokitan-sky-Kster-Hauser syndrome, Mullerian dysgenesis, vaginal aplasia ). The Mayer-Rokitansky-Kster-Hauser syndrome refers to the climical entity consisting of primary amenorrhea associated with congenital absence of the vagina, 46,XX karyototype, a rudimentary uterus or complete absense, normal overian function and normal ovulation, normal female breast development, body proprotion and body hair, frequent association of renal, skeletal and other cpngenital anomalies. This syndrome results from agenesis of both Mllerian ducts or from a failure of the Mllerian ducts to estavlish a proper communication with that part of the vagina from the urogenital sinus. A case of mayer-Rokitansky-Kster-Hauser syndrom was reviewed briefly.
