One hundred sixty one patients with the carcinoma of uterine cervix received curative radiotherapy at the Department of Therapeutic Radiology, Seoul National University Hospital between December, 1979 and December, 1982. According to FIGO classification; stage $I_a 1(0.6\%)\;1_b\;8(5.0\%),\;II_a\;31(19.3\%),\;II_b\;66(41.0\%),\;III_a\;3(1.8\;%),\;III_b\;46(28.6\%)\;and\;IV_a\;6(3.7\;%)$. The proportion of early stage cancer is too small because most of them treated by surgery. External beam whole pelvic irradiation was done first with 10MV x-ray or Co-60 gamma ray upto 4,000 or 5,000 rad for early and advanced cases, followed by one or two courses of intracavitary radiation using Fletcher-Suit Applicator loading c Cs-137. Supplementary external radiation to pelvic side wall to bring dose to 6,000 or 6,500 rads, if there is parametrial involvement or positive pelvic lymph node. Of the 161 Patients, 49 Patients were lost to follow-up but only 22 patients were lost in disease free state. And so, 86.3 percent of the patients were followed to time of recurrence or to date. The results are as follows ; 1. Locoregional control rates according to stage is: stage I $100\%,\;II_a\;90.3\;%,\;II_b\;75.8\%,\;III_a\;66.7\%,\;III_b\;58.7\%\;and\;IV_a\;16.7\%$, respectively. 2. Persistent or recurrent disease were localized in pelvic cavity in 32 of 50 patients and 6 had distant metastasis only. 3. Rectal bleeding was the most common complication and appeared mostly between 6 and 24 months after radiotherapy. Most of them had transient minor bleeding and only 2 patients needed transfusion and 1 patient needed colostomy due to rectovaginal fistula. 4. The 3 year disease free survival rate is: stage I $100\%,\;II_a\;78.0\%,\;II_b\;60.6\%,\;III_a\;66.7\;III_b\;46.3\%\;and\;IN_a\;16.7\%$, respectively.

This research focuses on the overall evaluation of tumor protein (p53) and cell growth marker (Ki-67) in their functions as carcinogenic factors in both a HPV-infected group and in a HPV-noninfected group with the precancerous dysplasia of uterine cervix. Histological grades were determined by the H&E staining and the expression level of p53 and Ki-67 were tested by the immunohistochemistry method. The results were as follows. Among the total of 66 cases, p53 (+) was observed in 19 cases (29.0%) from the mild grade group, 22 cases (33.0%) from the moderate grade group, and 19 cases (29.0%) from the severe grade group. The values correlate with the increase of dysplasia intensity in HPV-noninfected group and showed significant correlation (p<0.05), but there were no significant difference from the HPV-infected group. Among a total of 66 cases, the mitotic index of Ki-67 (+) were observed in 19 cases (29.0%) from the mild grade group, 22 cases (33.0%) from the moderate grade group, and 19 cases (29.0%) from the severe grade group. The values were significantly different against dysplasia intensity (p<0.05), but showed no significant difference from HPV infection. After cross comparing the statistical parameters of p53 and ki-67 in their significance, p53 was shown to be statistically significant with Ki-67 while there was no statistically significant difference with Ki-67 (p<0.05). Taken together, tumor protein (p53) and an index of Ki-67 observed in cervical dysplasia and in HPV related dysplasia of cervix uterine did not have any notable significance with HPV infection. The incidence rate of p53, however, had some significant correlation with dysplasia while Ki-67 had no particular statistical significance. As a result, p53 and Ki-67 can be considered as effective diagnostic markers in predicting the disease progression of dysplasia to cervical cancer.

This study was conducted to assess the predictive value of p-glycoprotein (p-gp) and p53 immunoexpression in human papillomavirus (HPV) infected cases of cervical dysplasia. Expression of both p-gp and p53 proteins was detected in cervical smears from 177 squamous intraepithelial lesions (SIL) cases along with 183 "atypical squamous cells of unknown significance" (ASCUS) and 150 normal cases. HPV 16 and 18 infection was detected by polymerase chain reaction using type-specific primers for HPV sub-types. There were no significant detectable p53 and p-gp expression in the normal cervix smears (p>0.05). In the ASCUS group 10 cases were positive for both p53 and p-gp immunoreactivity. In cervical dysplasia cases, p53 was positive in 86 (48.58%) while p-gp was positive in 93 (52.54%) and the two markers showed a highly significant correlation (r=0.92, p<0.001). Expression of p53 and p-gp was associated with grade of SIL (p<0.001). A positive correlation between the presence of HPV and expression of proteins p53 and p-gp in smears of patients with cervical lesions was also noted (p<0.001). Thus, p53 and p-gp immunostaining in cervical smears may act as an auxiliary biomarker for detection of HPV-associated cervical lesions. Additionally, a significant positive correlation between ascending grades of SIL and labeling indices of markers suggests that p53 and p-gp can be used as an adjunct to cytomorphological interpretation of conventional cervical Pap smears.

One hundred sixty three (163) animals were used in $2{\times}2$ and $3{\times}2$ factorial experiment in randomized complete block design (RCBD) to determine the effect of clitoral stimulation during timed inseminations on the fertility of Philippine swamp buffaloes (carabaos). There were 3 separate trials conducted with two treatment groups per trial : control and with 30 second clitoral stimulation after each insemination. Parity, tone of uterus and site of semen deposition were also used as criteria in subdividing the main groups. The pregnancy rates of animals that received clitoral stimulation were significantly (p<0.05 or p<0.01) higher than those of control for both caraheifers (52.98 vs 31.41%) and caracows (52.68 vs 27.07%) ; under all uterine conditions : tone 1 (53.33 vs 31.75%), tone 2 (35.83 vs 22.82%) and tone 3 (75.65 vs 42.44%) ; and in both site of semen placement, cervix (43.99 vs 22.85%) and uterus (60.92% vs 37.81%). Fertility was also significantly (p<0.05) higher when semen was deposited in the uterus (49.37%) than in the cervix (33.42%). Interaction effect was insignificant. Clitoral stimulation should be utilized as a routine procedure following artificial insemination in carabaos.

Cancer of the cervix is the most common malignancy in women in developing countries and the second most common cancer in women throughout the world with approximately 500,000 new cases each year. Prevention of this large number of premature deaths among women is, therefore, a goal worthy of urgent and serious consideration. Due to its high diagnostic disagreement among pathologists and large quantity of specimens, it is necessary to develop an automatic screening system measuring morphologic and densitometric features of the samples. Many research works have been published but most of them used Feulgen stained specimens which are not a usual staining method used in clinics. In this thesis, an automatic cancerous nucleus detection method essential to a screening system with papanicolaou stained specimens called Pap-smear is proposed which employs image processing techniques. It uses edge information to segment objects and morphologic as well as densitometric information to distinguish cancerous nuclei from dirts or normal nuclei. It has produced useful results in our study.

Purpose: This study aimed to identify the components of preterm birth (PTB) through women's personal narratives and to visualize clinical symptom expressions (CSEs). Methods: The participants were 11 women who gave birth before 37 weeks of gestational age. Personal narratives were collected by interactive unstructured storytelling via individual interviews, from August 8 to December 4, 2019 after receiving approval of the Institutional Review Board. The textual data were converted to PDF and analyzed using the MAXQDA program (VERBI Software). Results: The participants' mean age was 34.6 (±2.98) years, and five participants had a spontaneous vaginal birth. The following nine components of PTB were identified: obstetric condition, emotional condition, physical condition, medical condition, hospital environment, life-related stress, pregnancy-related stress, spousal support, and informational support. The top three codes were preterm labor, personal characteristics, and premature rupture of membrane, and the codes found for more than half of the participants were short cervix, fear of PTB, concern about fetal well-being, sleep difficulty, insufficient spousal and informational support, and physical difficulties. The top six CSEs were stress, hydramnios, false labor, concern about fetal wellbeing, true labor pain, and uterine contraction. "Stress" was ranked first in terms of frequency and "uterine contraction" had individual attributes. Conclusion: The text network analysis of narratives from women who gave birth preterm yielded nine PTB components and six CSEs. These nine components should be included for developing a reliable and valid scale for PTB risk and stress. The CSEs can be applied for assessing preterm labor, as well as considered as strategies for students in women's health nursing practicum.

In this report, laparoscopic ovariohysterectomy (LOHE) was performed on two, healthy, intact female dogs. Three ports, umbilical port for placing the laparoscope and the left and right paramedian instrument ports were placed into the abdominal cavity. First, in order to isolate the right ovary, the vascular pedicle was coagulated by activating the universal bipolar forceps. Then, the pedicle and suspensory ligament were transected by the bipolar electrocauterization scissors. In the same manner, the left ovary was isolated. The uterine body and the uterine arteries were coagulated bilaterally and transected just rostral to the cervix. The isolated ovaries and uterus were exteriorized through the left paramedian instrument port, which was extended by approximately 1 cm to allow for tissue removal. The skin and subcutaneous tissue were closed in a routine manner. Surgical times for LOHE in two dogs were 35, 40 min respectively. Total length of abdominal incision was shorter than 3 cm in two dogs. No clinical complications related to the LOHE were observed during 1.5 years after surgery. The LOHE is an alternative surgical technique that deserves further investigation.

This is a retrospective analysis of 67 patients with histologically proven invasive carcinoma of uterine cervix treated with surgery followed by adjuvant radiotherapy at Inje University Seoul Paik Hospital between october 1983 and september 1991, Postoperative radiotherapy was carried out in patients with high risks of locoregional recurrence such as positive pelvic lymph node (38 pts), large tumor size more than 3 cm (22 pts), cervical stromal invasion more than 2/3 (46 pts), parametrial involvement (9 pts), positive resection margin (14 pts), endo/myometrial extension (10 pts), and angiolymphatic invasion (13 pts). Stage I A, I B, and IIA were 2 $(3\%),$ 39 $(58.2\%),\;and\;26\;(38.8\%),$ respectively. Median follow-up period was 48 months with ranges from 13 to 115 months. All 67 patients were treated externally with standard pelvic field with radiation dose ranging from 4080 to 6120 cGy in 4~6 weeks period of time. Of these, 45 patients received intracavitary radiotherapy. The overall survival rate and disease free survival rate at 5-year were $88.0\%\;and\;82.1\%,$ respectively. The survival rates by stage were $87.1\%$ in IB and $88.4\%$ in IIA. Local control rate was $80.6\%(58\;pts).$ The treatment failure was noted in 12 of 67 patients $(17.9\%):$ locoregional failure in $7(10.4\%),$ distant metastasis in 3 $(4.5\%),$ and locoregional and distant metastasis in $2(3\%),$ The univariate analysis of prognostic factors disclosed endo/myometrial extension as a significant factor of survival and recurrence $(70.0\%\;vs\;91.1\%\;P<0.05\;&\;30.0\%\;vs\;15.8\%,\;respectively).$ The complication of postoperative radiothrapy was not significant and all patient were well tolerated. In conclusion, postoperative radiotherapy in patients with high risks of locoreginal recurrence is relatively well tolerated and it gives significantly improved survival rate especially in patients with positive lymph nodes, bulky tumor size $(\geqq3\;cm),$ parametrial involvement, cervical stromal invasion more than 2/3, positive resection margin and angiolymphatic invasion.
