During the reproductive period, human endometrium undergoes a pattern of cyclic change. Human endometrium undergoes a complex pattern of proliferation, secretory activity, and menstruation over an approximately 28 days period. Proliferative activity is highest during late proliferative phase under influence of estrogen, and minimal activity in the late secretory and menstrual phase. To study a possible change of telomerase activity during menstrual cycle, telomerase activities in normal and hormone treated endometrium were tested using telomerase repeat amplification protocol(TRAP) assay. Telomerase activities were detected in 9 of 10 proliferative endometrium(90%), and maximal activity was shown in late proliferative phase. Only 3 of 10 secretory endometrium(30%) revealed weak activity. However telomerase activity was not detected in menstrual phase endometrium(N 2) and senile endometrium(N=3). Four of tamoxifen treated endometrium(N 4) and 1 of provera treated endometrium(N 3) Levels of telomerase activity of treated endometrium(N 4) and late proliferative endometrium(N 6) were as high as them of detected in endometrial cancer and hyperplasia. Above findings reveal that telomerase activity of endometrium is changed according to menstrual cycle, And the level of telomerase activity is related to proliferative activity of endometrium that is dependent on the status of female sex steroid hormone and tamoxifen treatment.

Atherosclerotic heart disease is a major source of cardiovascular morbidity and mortality in adult populations. To assess the prevalence of anatomical and functional abnormalities of the heart in such patients, we studied total 50 subjects with atherosclerotic heart disease by echocardiography and compared with 27 control subjects. We found significant change(p<0.05) of aortic root dimension, left ventricular mass, mitral valve E-F slope, E-point septal separation, and functional measurements show significant change in ejection fraction and fractional shortening of left ventricle. Characteristically, abnormal septal movement reveals in 70% of patients including paradoxical, flat & diminished, hyperactive motion, and among them paradoxical movement is the most frequent. Also left ventricular posterior wall movement is abnormal in 30% of the patient group. The prevalence of echocardiographic abnormalities is 80 percentile of total, which include 30 percentile subjects with only echocardiographic abnormalities without abnormality in 12-lead ECG, chest X-ray and laboratory findings. And these abnormalities can be detected well by echocardiography before they were otherwise apparent.

Cardiovascular respons follwing ethanol ingeation was conapared in two groups of male college studenta; 20 who ahowed visble facial flushing and 25 whe showed on flushing. Ethanol was administered as 25% Korean liquor (Kumbokju) a dose of 2ml per kg body weight, the heart rate, blood pressure and respiratory rate were measured. The reaults areas follows. The heart rate after ethanol ingestion increased significantly in both flushing and non-flushing groups. However, the degree of the heart rate increased in the flushing group was aignificantly higher than that in the non-flushing group. The blood pressure was decreased significantly from 40minutes after ethanol ingestion in both groups. Howyer, the flushing group showed higher systolic pressure, and lower diastalic pressure and mean arterial pressure than the non-flushing group. The reapiratory rate following ethanol administration was increased in the flushing group but decreased in the non-flishing group when compared with the resting respiratory rate. The results clearly indicate that a signifcant difference in cardiovascular resoponrses to ethanol exists the flushing and non-flushing groups. The flushing group shows a greater tachycardia and greater fall in. mean arterial pressure followig ethanol ingestion than the non-flushing group.

Cardiovascular complications are major sources of morbidity and mortality in hypertensive patients. To assess the prevalence of anatomical and functional abnormalities of the heart in such patients, we studied total 67 sujects with systemic hypertension and hypertensive cardiovascular disease by echocardiography. Accordingly normal values of echocardiography from 27 control subjects, we found each significant change(p<0.05). of the septal thickness, left ventricular mass, mitral valve E-F slope and aortic dimension on the both groups, but functional measurements did only show significant change on the hypertensive cardiovascular group in contrast to hypertensive subjects group. The prevalence of the echocardiographic abnormalities on the simple hypertensive subjects group who have no abnormal 12-lead E.C.G. or Chest X-rays are orderly 14 subjects(64%) on the aortic root dimension, 9 subjects (41%) on the left ventricular posterior free-wall thickness and 7 subjects(32%) on the septal thickness. These findings demonstrated a high prevalence of cardiac abnormalities in a population of asymptomatic hypertensive subjects. And these abnormalities can be detected well by echocardiography before they were otherwise apparent.

E6 and E7 proteins produced by oncogenic HPV bind to the protein products of cellular tumor suppressor genes p53 and Rb, respectively. This mechanism has been suggested to contribute to the oncogenesis of HPV-infected carcinoma. The cells which are blocked the function of p53 and pub protein continue to divide by bypassing Ml stage known as antiproliferative mechanism but telomeres, the genetic elements at the ends of chromosomes, continue to shorten until the telomeres are so short that further replication is prevented(M2 stage). But telomeres can be maintained if telomerase is derepressed, giving rise to a immortal cell. The present study has been investigated the presence of HPV, telomere length and telomerase activation in cervical carcinomas. HPV DNA were detected by polymerase chain reaction in 17 of 19 precancerous lesions and cervical carcinoma specimens; HPV16 was detected in 12 cases, HPV18 in one case, HPV33 in two cases, and HPV58 in two cases. Overall, the prevalence of HPV was 89.5%. To study the difference of telomere length in cervical carcinomas and each normal counterpart, DNAs were digested with Hinf III and Rsa I to liberate the terminal restriction fragments(TRF). TRFs were resolved on agarose gels and detected by hybridization to the telomeric probe. This result indicated that there were no significant difference of TRF length in samples tested except two cases. TRF length of one carcinoma specimen was found to be significantly increased as compared with normal counterpart, but the other was found to be significantly decreased. Telomerase activity was detected in 4 of dysplasia specimens(5 cases), all of carcinoma in situ(CIS), and 6 of 8 invasive carcinoma. Overall, telomerase activity was detected in 84%. The degree of telomerase activity was high in 2 of dysplasia, 3 of CIS, and 3 of invasive carcinoma. And then there was no apparent association between HPV types and levels of telomerase activity. However, telomerase activity was depressed in invasive carcinoma as compared to dysplasia and CIS. These results suggest that HPV may be a possible causative agent in cervical carcinoma. In addition, telomerase activation may be necessary for the immortalization of cells and the progression of malignancy in cervical carcinoma.

OBJECTIVE: To determine the value of sonographic nuchal translucency measurement for the detection of chromosomal abnormalities in high risk pregnancies. METHOD: The feasibility of nuchal translucency was tested in a prospective study of 1260 pregnancies at 10- 13 weeks' gestation. RESULTS: The nuchal translucency of 3 mm or greater was identified in 41 fetuses (3.2%), 19 of whom proved subsequently by either amniocentesis or postnatal follow-up have chromosomal abnormalities. The sensitivity of nuchal translucency for chromosomal abnormalities was 82.6% (19 of 23 cases), the positive predictive value of nuchal translucency for chromosomal abnormalities detection was 46.3% (19 of 41 cases). CONCLUSION: The observed sensitivity, false-positive rate and predictive value suggest that sonographic nuchal translucency should be undertaken at 10 to 13 weeks of gestation.

Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.

Background: This study aimed to evaluate the effectiveness of conservative treatment in selected patients with atraumatic medial sesamoid pain (MSP) that developed during sports activities. The secondary aim was to determine the detailed underlying pathology in patients who did not respond to conservative treatment using magnetic resonance imaging (MRI). Methods: From March 2015 to August 2022, we prospectively followed 27 patients who presented to our outpatient clinic with atraumatic sports-related MSP. The conservative treatment protocol for MSP included the use of oral analgesics, activity restriction, insole modification, local corticosteroid injections, and boot walker application with crutches. MRI was performed for all patients who experienced persistent pain despite the completion of conservative treatment. Results: After the completion of the conservative treatment protocol, 48.1% of the patients reported a reduction in pain. Patients with younger age at pain onset (p = 0.001), higher body mass index (p = 0.001), and a bipartite medial sesamoid (p = 0.010) were more likely to experience persistent pain after conservative treatment. The type of sports activity was also a factor since runningand dancing-related MSP tended to respond better to conservative treatment compared to MSP originating from golf, futsal, and weightlifting with squatting. On MRI, 42.8% of patients showed no specific abnormal findings, with signal changes in soft tissues such as the subcutaneous fat and bursa being the most common, followed by intraosseous signal changes of the medial sesamoid bone and chondral or subchondral lesions of the medial sesamoid metatarsal joint (28.6% each). Conclusions Conservative treatment was successful in less than half of the patients who experienced MSP due to sports activity. Practitioners should be aware of the numerous possible causes of conservative treatment failure, such as bursitis, medial sesamoiditis, stress fracture, or chondral lesions between the medial sesamoid and metatarsal. MRI evaluation may be helpful in MSP patients who do not respond to conservative treatment.

We report a case of an anomalous origin of left coronary artery from the pulmonary artery with severe mitral regurgitation. A 20-year-old female was admitted to hospital for recurrent syncope and dyspnea on exertion. Cardiac ausculatation revealed systolic murmur radiating to left axilla and blood pressure of 90/70 mmHg. Electrocardiography showed a nonspecific ST-T wave change on V1, V2, V6, I, & aVL leads. Holter monitering showed no significant abnormality except occasional premature ventricular complexes. Chest radiography showed mild cardiomegaly with mitral valvular heart configuration and no pulmonary abnormality. Echocardiography showed normal left ventricular dimension and systolic function with marked dilated left atrium, severe mitral regurgitation, & severe resting pulmonary hypertension. Aortogram didn't show left coronary artery ostium. Right coronary angiogram showed normal right coronary artery which supplied major left epicardial coronary arteries via good collaterals (Rentrop grade III). Pulmonary angiogram showed anomalous origin of left coronary artery from main pulmonary trunk. She underwent mitral valvuloplasty and coronary artery bypass graft.

Suction curettage is a relatively safe procedure to induce abortion of first trimester pregnancy with a very low complication rate. But, in order to do that, cervix should be dilated enough to pass operating devices. We experienced a case of first trimester pregnancy terminated successfully using transvaginal misoprostol when suction curettage was failed due to severely cervical stenosis after LEEP conization.
