Medroxyprogesterone acetate(MPA) is one of the most commonly used hormonal agents for the treatment of advanced or recurrent endometrial adenocarcinoma. However, the progesterone receptor content of endometrial carcinoma varies directly to the degree of differentiation and inversely with stage of the tumor. Thus one would predict that MPA therapy would be less effective in advanced and poorly differentiated tumors. In addition, MPA has been shown to reduce progesterone receptor content of both normal and malignant endometrial cells, which could result in loss of hormone responsiveness. Tamoxifen, which is often used in breast cancer therapy, has also been used in the treatment of patients with advanced and recurrent endometrial carcinoma. Tamoxifen is known to have some estrogenic effects at low concentration and one of these effects is induction of progesterone receptor both in normal and malignant endometrium. This property has focused interest on sequential or simultaneous use of tamoxifen and MPA in the therapy of endometrial carcinoma. The growth inhibitory effects of MPA and tamoxifen were tested on six longestablished endometrial carinoma cell line(HEC-1-A, HEC-1-B, RL 95-2, AN3CA, KLE) and on SCHE-1, a new endometrial carcinoma cell line established in our laboratory. MPA and tamoxifen were used in growth experiments either alone, simultaneously or sequentially. The MCF-7 breast cancer cell line was used as a control. Only 20% reduction in cell number was achieved after 10 days of exposure to the drug, even with the highest MPA concentration tested(10micronm) in endometrial carcinoma cell lines. But in MCF-7 cells, 60% reduction in cell number was achieved with the same concentration of MPA(10um). Ten days of feeding with 5micronm tamoxifen produced a 96% reduction in cell number in MCF-7, a 91% reduction in HEC-1-A, a 88% reduction in HEC-1-B, a 98% reduction in AN3CA and a 71% reduction in KLE cultures. In SCHE-1 cultures a 83% reduction in cell growth was seen and no viable cells remainde in RL 95-2 cultures after 10 days of feeding with a 5uM tamoxifen. In AN3CA cultures, simultaneous exposure to 5um tamoxifen and 5um MPA resulted in partial reversal of the tamoxifen-induced growth inhibition. In RL 95-2, HEC-1-A and HEC-1-B cultures, simultaneous use of these drugs had the same effect as tamoxifen alone, whereas in KLE and SCHE-1 cultures a slight additive growth effect was observed. All six endometrial carcinoma cell lines resumed logarithmic growth when medium containing tamoxifen of logarithmic growth under these conditions was slower than that in the other endometrial carcinoma cultures. Our results show that MPA does not have growth inhibitory effects in these endometrial carcinoma cell cultures, whereas tamoxifen has been shown to have potent endometrial carcinoma cells. These findings are of special importance since patients who are most likely to need adjuvant therapy for advanced or recurrent endometrial carcinoma are those with estrogen receptor and progesterone receptor negative tumors.

A considerable body of evidence has been accumulated suggesting that invasive squamous cell carcinoma develops from cervical intraepithelial neoplasia(CIN). Most women with invasive cancer of the cervix are from lower socioeconomic groups, have begun heterosexual activity early in life, marry early, are multiparous, and have many sexual partners. Although the epidemiology of the cervical cancer is known well, the pathogenesis of the cervical cancer from CIN is subtle yet. Apoptosis, including the programmed cell death, is important event in normal cell turnover and maintenance of adult tissues. Apoptosis exerts a homeostatic function in relation to tissues dynamics, as the steady state of continuously renewing tissues achieved by a balance between cell replication and cell death. The specific labelling of nick ends of fragmented DNA was used to see the apoptotic cells from normal epithelium of the cervix to invasive cervical cancer. The apoptotic cells were found normally in the parabasal layer of the epithelium. As the grade of CIN increase, the apoptotic cell were found in superficial of the cervix and number of the apoptotic cell were increased. In the cervical cancer, the apoptotic cell were found in the cancerous tissues more than in the normal epithelium. This results suggest that the cell proliferation is more important than the inhibition of the apoptosis in the carcinogenesis of the cervical cancer.

OBJECTIVE: A polymerase chain reaction (PCR) was developed in the detection of Chlamydia(C) trachomatis, Mycoplasma(M) hominis and Ureaplasma(U) urealyticum, which have been common causes of sexual transmitted diseases in the female genital tracts and in neonatal infection. To investigate tbe frequency of these organisms in the female genital tract infection and to know any association of these infections with clinical manifestations, PCR was performed. METHODS: PCR was performed in 300 cases of vaginal swabs and 154 paraffin embedded tissues including 50 cases of chronic endometritis, 50 cases of cleonic salpingitis, 50 cases of ectopic tubal pregnancy and 4 cases of normal endometrium. RESULTS: Among 300 cases of vaginal swabs, C. trachomatis, M. hominis and U. urealyticum were detected in 1.3%, 4.0%, and 29.6%, respectively. Mixed infection was found in 12.0%. the overall positive rate was 47.0%. The cytologic features from C. trachomatis, M. hominis and U. urealyticum positive patients revealed no specific findings. The clinical manifestations between positive and negative cases for these organisms had no differences. In tissue samples, only C. trachomatis was detected 2% of chronic endometritis, 8% of chronic salpingitis and 4% of ectopic tubal pregnancy. CONCLUSION: With the above results, it suggests C. trachomatis can evoke an ascending chronic infection of the female genital tracts and ectopic tubal pegnancy,

Multicystic ovary was first described by Silver in 1958 as a rare case feature of acquired primary hypothyroidism. In 1980, Lindsay reported four girls with hypothyroidism associated with multicystic ovary diagnosed by pelvic ultrasonography. The mechanism of ovarian cyst formation and pseudoprecocious puberty in severe hypothyroidism in childhood are unknown. Increased ovarian sensitivity to GnRH and increased TSH level which acts on FSH receptor is one of the mechanism explained. We report a case of a girl with primary hypothyroidism presented with pseudoprecocious puberty and giant follicular ovarian cyst with torsion.

The reports of all amniocentesis samples received in our cytogenetic laboratory from 1986 to 1998 were reviewed to identify cases in which culture failure of amniocytes occurred. Medical records were then reviewed for the prenatal ultrasonographic findings, karyotype when available, and clinical outcome. We investigated the clinical aspects associated with second trimester amniotic fluid cell culture failure. During the study period, 5,325 second trimester amniotic fluid samples were processed, of which 42(0.8%) failed to yield a result. Ninety-seven percent of the samples were obtained before 24 weeks' gestation, mainly because of advanced maternal age. Three percent of the samples were obtained after 24 weeks' gestation. Culture failure was more common in samples obtained after or at 24 weeks' gestation(11.8%) than in those obtained before 24 weeks(0.44%)(p<0.05, chi-square test). This difference was also observed when the results were analysed according to the cases with known normal or abnormal karyotypes, The frequency of culture failure did not differ significantly between the groups with normal and abnormal karyotypes. We conduded that amniotic fluid cell culture failure is more common in advanced pregnancy and is not associated with a higher incidence of chromosomal abnormalities.
