Purpose : This study was aimed to investigate the inhibitory effect of Sparganii Rhizoma on the proliferation of human uterine leiomyoma cells and the expression of gene related the mechanism of cell apoptosis. Methods : This study was evaluated the number of death cells treated with indicated concentration of Sparganii Rhizoma and investigated cell death rate by MTS assay. Furthermore, fluorescence-activated cell sorter analysis and DNA fragmentation assay were used to dissect between necrosis and apoptosis. and then we observed the differential gene expression by western blot analysis. Results :1) The inhibitory effect on the growth of uterine leiomyoma cell treated with Sparganii Rhizoma was increased in a dose dependent manner. 2) As the result of FACS analysis, subG1 phase incrase was observed 23.49% inuterine leiomyoma cell treated with Sparganii Rhizoma at $500\;{\mu}g/ml$ compared to control.. 3) The gene expression of p53, p21 related cell apoptosis was increased according to increasing concentration but p27 was none exchanged. 4) The expression of cyclin A, D and E was decreased in a concentration proportional and then the dephosphorylation of pRb was increased. 5) The character of apoptosis, DNA fragmentation was significantly observed according to increasing concentration. 6) The expression of pro-caspase3 were decreased dependent on treatment concentration and activated PARP took place. Conclusion : The inhibitory effect of Sparganii Rhizoma on the proliferation of human uterine leiomyoma cells was observed with apoptosis and cell cycle arrest. These data suggest that Sparganii Rhizoma might be candidate of medical therapy for uterine leiomyoma.

Leiomyomas, which are the commonest pelvic tumors in women, are originated from myometrial cells. Although the exact initial pathophysiologic event of the leiomyoma is not known, recent evidences suggested that the effects of sex steroid hormones in the process of tumor growth are mediated by local production of growth factors including epidermal growth factor (EGF), insulin-like growth factor-I (IGF-I) and insulin-like growth factor-II (IGF-II). If we look at the effects of other cytokines, it was suggested that basic fibroblast growth factor (bFGF) may stimulate the proliferation of myometrial and leiomyomas cells. And it was reported that interferon-${\alpha}$ inhibit the action of bFGF. Therefore, we examined the effect of bFGF and interferon-${\alpha}$ on the proliferation of leiomyoma and myometrial cells. bFGF stimulated the myometrial and leiomyoma cells significantly at the concentration of 1ng/ml (p<0.05) and 5ng/ml (p<0.05). However, Interferon-${\alpha}$ inhibited the cell proliferation of myometrial and leiomyoma cells significantly at the concentration of 100U/ml (p<0.05) and 1000U/ml (p<0.05). And the stimulated effects of bFGF with the various concentration on the myometrial and leiomyoma cells ware inhibited by interferon-${\alpha}$ with 100U/ml. Therefore, we concluded that bFGF may stimulate the myometrial and leiomyoma cell proliferation and interferon-${\alpha}$ may inhibit the myometrial and leiomyoma cell proliferation through blocking the effect of basic fibroblast growth factor.

Purpose : This study was aimed to investigate the inhibitory effect of Leonurus sibiricus on the proliferation of human uterine leiomyoma cells and the expression of gene related the mechanism of cell apoptosis. Methods : We counted the number of death cells treated with indicated concentration of Leonurus sibiricus and investigated cell death rate by MTS assay. Furthermore, flow cytometry analysis and DNA fragmentation assay were used to dissect between necrosis and apoptosis and then we observed the differential gene expression by western blot analysis. Results : Leonurus sibiricus significantly inhibited the proliferation of uterine leiomyoma cell in a dose-dependent and time dependent manner. Fluorescence activated cell sorter (FACS) analysis indicated that Leonurus sibiricus induced G1 cell cycle arrest. Leonurus sibiricus enhanced the expression of p27 and p53 with cell cycle arrest. Conclusion : These findings suggest that Leonurus sibiricus is a candidate agent for the treatment of uterine leiomyoma. p27, $p53^{1}$ may play an important role in Leonurus sibiricus-induced cell cycle arrest and cell growth inhibition.

Benign metastasizing leiomyoma (BML) is a rare disease, which usually occurs in women with a history of a prior hysterectomy or myomectomy for benign uterine leiomyoma, and has the potential to metastasize to distant sites, such as the lung, lymph nodes, muscular tissue, heart, or retroperitoneum. These lesions are slow-growing, asymptomatic, and usually found incidentally. The prognosis of BML is also excellent. However, there has been debate on the origin and the correct classification of BML, and there are no guidelines for the treatment of BML. We report here on a rare case of BML in both the retroperitoneal cavity and lung in a 48-year-old woman with a history of hysterectomy due to histologically benign uterine leiomyoma. The patient underwent retroperitoneal mass excision and bilateral salpingo-oophorectomy, and then wedge biopsy of two pulmonary nodules was performed additionally 9 days later. Until now, there has been no sign of recurrence and the patient remains asymptomatic. To our knowledge, pulmonary BML is rare and the co-existence of the retroperitoneal metastases after previous hysterectomy is even rarer.

Intramural leiomyoma is the most common benign esophageal tumor, but it is rare compared with carcinoma. Although the most common symptom is dysphagia, this tumor may not cause symptoms before attaining large size. Radiographic and endoscopic findings allow an accurate diagnosis to be made before operation in most patients. The treatment of choice is enucleation without mucosal encroachment. Recently, we experienced two cases of esophageal leiomyoma on the mid portion of esophagus and enucleation of tumors were done by blunt dissection with caution. In one case, postoperative chylothorax was complicated, but cured with conservative treatment. The tissue diagnosis was confirmed with pathological finding.

Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. 1,2) Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. 3) Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion 4) and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.

This is a report of leiomyoma in the esophagus. patient had suffered from mild intermittent dysphagia on eating without any other complaints. This complaint had been going for 45 days, but was not progressed. The esophagogram revealed an ovoid walnut-sized smooth filling defect in the midportion of the esophagus. The mucosal folds of the esophagus were not destroyed. A benign intramural tumor of the esophagus, such as leiomyoma, was suspected with X-ray finding and clinical features. On Aug. 13, 1976 a thoracotomy was performed at right 4th intercostal space. A firm, irregular shaped mass in the wall of the esophagus was enucleated by blunt dissection without any injury of the mucosa of the esophagus. The diagnosis of leiomyoma was confirmed with histopathological finding. Postoperative course was uneventful.
