Purpose : This study was done to analyze survivals, patterns of failure, and complications of early uterine cervix cancer after curative radiotherapy. Materials and Methods : Eighty patients with uterine cervix cancer FIGO Stage IB (48 cases) and Stage IIA (32 cases) treated with radiotherapy were analyzed retrospectively. Patients were treated from November 1985 to May 1993, and minimum follow up period was 24 months and 6 cases were lost to follow up. All of them were treated with external radiotherapy and different fractions of high dose rate intracavitary radiotherapy, Survival rates, failure patterns, complication rates and degrees of severity were analyzed according to several factors. Results : Overall 5 year survival rate and relapse free survival rate were $72.3\%$, and $72.8\%$ respectively. Prognostic factors were stage, size, pathology, RT response and there was no significant survival difference among the reasons of radiotherapy choice. There were 19 cases of treatment failure, another 3 cases were not tumor related death, and most of treatment related failure occurred within 24 months Late complication rate of bladder and rectum were $8.8\%,\;15\%$ respectively, frequency and severity of complication were correlated with ICR fractionation dose and total dose. Conclusion : These results showed that survival rates of early stage radiation treated cervix cancer patients were comparable to surgical series, but more aggressive treatment methods needed for stage IIA poor prognostic patients. To decrease late complication, choice of proper ICR dose and meticulous vaginal packing is needed.

To investigate the role of interleukin-l$\beta$ (IL-1$\beta$) in the embryonic development, in vivo and in vitro expression patterns of IL-1$\beta$ gene in the preimplantation mouse embryos were examined by RT-PCR, and the effects of explanted mouse ovi-duct and uterine epithelial cells on the expression of IL-1$\beta$ gene in the pleimplantation mouse embryos were examined by co-culture. IL-1$\beta$ mRNA was detected in the embryos from 4-cell stage to blastocyst stage in vivo and from morula stage to hatching blastocyst stage in vitro. This transcript was not detected from the GV stage to late 2-cell stage in vivo, and not at the 4-cell and 8-cell stages in vitro. For the co-culture of late 2-cell embryos with the explanted mouse oviduct and uterine epithelial cells, oviducts and uterine epithelial cells were isolated at 48 hour alter the hCG injection. The explanted oviduct and uterine epithelial cells in co-culture groups facilitated the IL-1$\beta$ gene expression of the mouse embryos in comparison with the control. Taken together these results suggest that the presence of IL-1$\beta$ plays an important role in preimplantation embryonic development. In addition, the up-regulation of IL-1$\beta$ gene expression by the explanted oviduct and uterine epithelial cells demonstrates that embryonic expression of IL-l$\beta$ gene may be regulated by the interaction with oviductal and uterine factor (s).

Leiomyoma of the bronchus is a very rare benign tumor of the lung. Most endobronchial leiomyomas occur as secondary foci of primary uterine leiomyoma. We herein report a case with endobronchial tumor that had a different pathology from a primary resected uterine leiomyoma and was therefor considered a primary endobronchial leiomyoma. A 51-year-old woman with a history of uterine myoma presented with productive cough and fever. Bronchoscopy revealed a lightly yellow colored mass lesion that totally obstructed the orifice of the left lower lobe of the lung. The diagnosis of leiomyoma was made by histological examination of the obtained specimen. We considered the possibility of a benign metastasizing pulmonary leiomyoma. For treatment and differential diagnosis, a left lower lobe lobectomy of the lung and total hysterectomy with bilateral salphingooopherectomy were performed. The differences between lung and uterine lesions were confirmed by morphologic finding and immunohistochemical staining. The pathological diagnosis was primary endobronchial leiomyoma combined with uterine myoma.

Purpose: The purpose of this study was to investigate the clinical findings, treatment, and outcome of patients with glassy cell carcinoma of cervix. Materials and Methods: We reviewed all cases of glassy cell carcinoma of the uterine cervix confirmed and treated at the Dongsan Medical Center, Keimyung University, between January 1993 and December 2005. There were 7 cases with histopathologically confirmed gassy cell carcinoma. A tumor was diagnosed as glassy cell carcinoma if over 50% of the tumor cell type displayed glassy cell features. Six patients with stage IB had radical hysterectomy and bilateral pelvic node dissection, and 2 of them received adjuvant external pelvic irradiation with concurrent chemotherapy. Remaining one patient with stage IIA had curative concurrent chemoradiotherapy with external pelvic irradiation and brachytherapy. Results: There were 7 patients diagnosed as glassy cell carcinoma among the 3,745 (0.2%) patients of carcinoma of uterine cervix. The mean age of 7 patients was 44 years with range of 35 to 53 years of age. The most frequent symptom was vaginal bleeding (86%). By the punch biopsy undertaken before treatment of 7 cases, 2 only cases could diagnose as glassy cell carcinoma of uterine cervix, but remaining of them confirmed by surgical pathological examination. The mean follow up duration was 73 months with range of 13 to 150 months. All 7 patients were alive without disease after treatment. Conclusion: Glassy cell carcinoma of the uterine cervix is a distinct clinicopathologic entity that demonstrates an aggressive biologic behavior. However for early-stage disease, we may have more favorable clinical outcome with radical surgery followed by chemoradiothery.

Objective: This study was performed to investigate the efficacy and safety of radiofrequency (RF) myolysis under transvaginal ultrasound guidance. Methods: Transvaginal RF myolysis had been performed in one hundred nine women with uterine leiomyoma at Chung-Ang University hospital between Dec. 2004 and Mar. 2007. All patients, mean aged $42.8{\pm}5.8$ years, desired their uterine conservation. Patients underwent physical examination, transvaginal pelvic ultrasound for measurement of the lesions preoperatively. Follow up was done at 1 week, 1 month, 3 months, 6 months after RF myolysis by same physician and measurement of size and volume of myoma and improvement of myoma specific symptoms such as menorrhagia and dysmenorrhea were checked at each visit. Results: The mean maximal diameter of myomas treated by RF myolysis was $6.1{\pm}0.5\;cm$ and average time of the procedure was $16.3{\pm}8.5$ minutes. A significant decrease of myoma size and volume was observed at 1 month after myolysis. Mean reduction in maximal diameter was $29.9{\pm}4.8%$ at 1 week (p<0.001), $41.5{\pm}1.5%$ at 1 month (p=0.05), $46.2{\pm}3.9%$ at 3 months (p=0.003), $54.6{\pm}6.1%$ at 6 months (p<0.001) after RF myolysis respectively. Mean reduction in volume was $44.4{\pm}8.3%$ (p=0.001), $68.1{\pm}4.2%$ (p=0.035), 73.9$73.9{\pm}4.8%$ (p=0.042), $84.5{\pm}5.1%$ (p<0.001) at the same follow up period respectively. Significant improvement of symptom was observed at 3 months after RF myolysis. Transient low abdominal pain and prolonged vaginal bleeding were detected in 3 patients each but spontaneously resolved and no serious complication has been noticed or found. Conclusion: This study shows transvaginal RF myolysis could be a safe and effective method to treat uterine leiomyoma, allowing uterine conservation with significant volume reduction and rapid return to normal activity.

Thirty-four patients with suspected ectopic pregnancy whose serum hCG levels had been measured by beta-hCG EIA before surgery were evaluated retrospectively. The results were as follows: 1. Final diagnosis of thirty-four patients with suspected ectopic pregnancy comprised twenty- eight tubal pregnancy, five ruptures of hemorrhagic corpus luteum and, one tubo-ovarian abscess. One of the five patients with rupture of hemorrhagic corpus luteum was accompanied by missed abortion. 2. Range of serum hCG levels in twenty-eight patients with tubal pregnancy was 59-21,980 mIU/ml and that of four patients with rupture of hemorrhagic corpus luteum and one patient with tubo-ovarian abscess was 0.6-6.6mIU/ml. Serum hCG level of a patient with rupture of hemorrhagic corpus luteum who was accompanied by missed abostion was 200 mIU/ml. 3. Serum hCG levels in twenty-two of twenty-eight patients with tubal pregnancy were lower than 3,000 mIU/ml. Low serum hCG level below 100mIU/ml and high serum hCG level above 6,500 mIU/ml were noticed in four and six patients with tubal pregnancy, respectively. 4. Mean serum hCG levels (${\pm}SD$) of twelve patients with tubal pregnancy who had intra-abdominal free blood of less than 500ml and sixteen patients with tubal pregnancy who had intra-abdominal free blood of more than 500ml were 4,131 (${\pm}7,801$) mIU/ml and 3,208 (${\pm}5,081$) mIU/ml, respectively. There was no statistical difference in the mean level of serum hCG between both group (P>0.05). 5. Mean serum hCG levels (${\pm}SD$) of thirteen patients with unruptured tubal pregnancy and fifteen patients with ruptured tubal pregnancy were 2,628 (${\pm}5,448$) mIU/ml and 4,449 (${\pm}6,938$) mIU/ml, respectively. Mean level of serum hCG was statistically higher in ruptured tubal pregnancy (P<0.01). 6. Positive rate of urine pregnancy test in the diagnosis of ectopic pregnancy was 64% (16/25) and mean range of serum hCG level of nine patients with false negative result were 353 mIU/ml and 59-933 mIU/ml.

A 10-year-old spayed female Pekinese dog was referred to veterinary medical teaching hospital of Chonbuk National University with signs of dysuria, abdominal distension, and hematuria. Abdominal radiography revealed a large oval soft tissue mass in cranial abdomen, which was a fluid filled cyst containing a round mass by ultrasonography. Exploratory laparatomy found a 4 cm cyst containing reddish brown fluid and a 1.5 cm small round mass attached to the wall. Cytological impression of the imprint smears of the resected mass were highly malignant adenocarcinoma, which was confirmed by histopathology of the mass and the cyst. After the surgery the patient recovered uneventfully and discharged. The tumor recurred about one year after surgery, and second surgery performed at the owner's request. However the tumor recurred in two months with metastatic disease in the lung and the dog survived three more months after surgery.

Epidermal growth facter(EGF)는 내열성이 강하고 분자량이 6045 dalton인 단쇄상의 polypeptide로써, Cohen에 의해 생쥐의 악하선에서 처음 발견된 이래, 여러학자들에 의해 많은 연구가 되어왔다. 인체의 EGF는 urogastrone이라고도 불리우며, 인체의 소변에서 처음 검출되었고 분자구조 및 생리작용이 생쥐의 EGF와 매우 유사한 것으로 판명되었다. EGF의 자세한 작용기전은 확실히 규명되어있지는 않지만 세포의 증식과 분화를 촉진시키며 위산의 분비를 억제시킨다고 알려져 있다. 또한 EGF receptor는 분자량이 170,000${\sim}$180,000dalton인 세포표면의 polypeptide로써 인체, 쥐, 닭, 소 등의 세포막조직에 특이하게 결합되어 있다. 최근 수년동안 몇몇 학자들에 의해 EGF가 배아와 태아 및 태반의 성장을 촉진시키고 chorionic gonadotrophin과 placental lactogen의 분비를 증진하는데 기여할 것이라고 가정되어 왔다. 그러나 아직까지 배아착상에 대한 EGF의 작용여부에 관해서는 발표된 문헌이 없어 저자는 radioreceptor assay를 이용하여 EGF receptor binding과 토끼의 배아착상과의 관계를 규명하고자 임신경과에 따른 착상부위와 비착상부위의 자궁 및 태아측 태반과 모체측 태반을 분리취득하고 receptor binding assay를 시행하여 다음과 같은 결론을 얻었다. 1. 전임신군과 비임신군의 자궁조직의 membrane fraction으로부터 specific한 EGF receptor binding이 관찰되었다. 2. 착상전 임신 3일에 자궁조직의 EGF receptor수는 4.72 +0.16($10\;mol/{\mu}g$)로 비임신시보다 의의있게 증가되어 있었고(p<0.01), 착상시기인 임신 7일에는 착상된 부위에서 20.33+6.58로 훨씬 더 높은 측정치를 나타내었다(p<0.05). 3. 착상이후 가장 먼저 취득된 임신 14일의 태아측 태반은 모체측 태반의 1.39+0.49에 비해 훨씬 높은 11.94+1.97의 EGF receptor 측정치를 보였다 (p<0.01). 4. 이상의 소견들로 보아 EGF가 토끼의 배아착상에 밀접한 관련이 있을 것으로 추측되며, 이러한 착상전후의 EGF의 작용은 태아측으로부터 일 것으로 예상된다.

Uterine cervical cancer is the most common malignancy in korean women. In spite of recent development of early diagnostic and therapeutic modalities, about 40% of treated patient will develop relapse. So more aggressive local treatment such as more extensive surgery and higher radiation dose and administration of systemic chemotherapy will promote the curability but treatment related complications can not be avoidable. We used 22 cases of early cervical cancer, treated with surgery and post-operative radiotherapy, clinical data of these patients were analized to determine relationship between clinical parameters and final outcome. Three out of 22 cases revealed relapse and one patient showed rectovaginal fistula and another patient showed small bowel obstruction and the other patient showed rectal obstruction. Two out of three recurrence were stage IIa and the other one case was stage Ib adenocarcinoma with lymphovascular involvement. Nineteen out of 22 cases were followed without remarkable side effect or treatment related complication or sequelae. We concluded that our treatment policy was safe and effective to eradicate high risk postoperative cervical cancer with acceptable side effects or complication.

Purpose: The menstrual cycle of normal premenopausal patients was divide into menstrual flow phase, proliferative phase, ovulatory phase, secretory phase. The aim of this study was to ovarian and endometrial $^{18}F$-FDG uptake during the menstrual cycle in normal premenopausal patients. Materials and Methods: We identified 200 incidental $^{18}F$-FDG uptake in the ovary. The patient fasted at least 6 hours before receiving an intravenous injection of 370-592 MBq (10-16mCi) of $^{18}F$-FDG. Scanning from the base of the skull though the mid thigh was performed using the Discovery Ste PET/CT system (GE Healthcare, Milwaukee, WI, USA). Ovarian and endometrial $^{18}F$-FDG uptake (expressed as standardized uptake value) was measured on PET/CT image. Results: Two peaks of increased endometrial $^{18}F$-FDG uptake were identified during the menstrual cycle. The $SUV_{avg}$ and $SUV_{max}$ was $2.89{\pm}1.04$ and $3.17{\pm}1.59$ in menstruating patients, $2.4{\pm}0.88$ and $2.98{\pm}1.14$ in proliferative phase patients, $3.59{\pm}1.76$ and $3.17{\pm}1.67$ in ovulatory phase patients, $2.58{\pm}1.39$ and $3.1{\pm}1.8$ in secretory phase patients. Conclusions: Increased ovarian and endometrial $^{18}F$-FDG uptake could be found the time of menstrual flow and ovulatory phase of menstrual cycle. Increased uptake in endometrial adjacent to a cervical tumor does not necessarily reflect endometrial tumor invasion. Since increased uptake was dependent on the menstrual cycle, it can be avoided by scheduling PET/CT just after menstruation. Non-menstrual-related endometrial uptake may be instrumental in establishing a diagnosis in a premenopaual patient.
