The purpose of this study was to investigate that there was any differences of uptake ratio of Tc99-m-MDP during the healing process related to fracture level in tibia. Thirty mature rabbits were devided into three groups and each group consisted of ten rabbits. The osteotomy was performed at the proximal third of tibia in group I, at the middle third in group II and at the distal third in group III, respectively. After fracture was reduced, the fractured tibia was fixed with K-wire and immobilized with long leg cast. Serial Tc-99m-MDP scintigraphy with pixel counting method was performed in thirty cases of tibial shaft fracture from one day to eight weeks after fracture. The results obtained were as follows: l. In group I, the mean uptake ratio of Tc-99m-MDP at fracture site was 1.40±0.45 at two days after fracture, 3.34±1.21 at two weeks and increased rapidly to a maximal value of 7.51%1.01 at three weeks and decreased thereafter to 4.530.83 at eight weeks. 2. In group II, the mean uptake ratio was 1.10±0.10 at three days, 3.931.±10 at three weeks and increased rapidly to a maximal value of 7.37±2.21 at four weeks and decreased thereafter to 4.54±0.96 at eight weeks. 3. In group III, the mean uptake ratio was 1.13 ± 0.11 at three days, 3.95±0.93 at three weeks and increased rapidly to a maximal value of 7.43±1.72 at four weeks and decreased thereafter to 4.69±0.93 at eight weeks. These experiments suggest that the changes of Tc-99m-MDP scintigraphy in the proximal third fractures of tibia was earlier than middle or distal third fractures and there was no differences between middle and distal third fractures of the tibia.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

This study was performed ta evaluate difference of colposcopic findings between carcinoma in situ and microinvasive carcinoma. From August l, 1988 through November 30,1989, the conixation was undertaken in 138 patients. We compeied colposcpic findings with hiatologic diagnoiis on 1656 seetions. Comparison between the microinvasive carcinorna and the carcinoma in situ groups showed a significant higher incidence of large exoeervtcal lesion size(>3/2 33.9% vs. 1.2%), circumscribved location around external cervical os.(75.0% vs, 51.2%), combined abnormal colposcopic findings(19.6/a vs. 3. 7%) and deep endocervical involvement( >lcm : 23,2% vs. 7. 3%). (P<0.01) Granular area was showed 11% incidence of the worst histologic diagnosis.

OBJECTIVE: The object of this study was to compare the diagnostic accuracy of a sonographic morphologic scoting system, the serum CA-125 assay, and a combination of both in patients undergoing laparotomy for a clinically diagnosed adnexal mass. METHODS: In 129 consecutive patients, the morphology of the mass was evaluated and scored by the morphologic scoring system of Sassones using transabdominal or transvaginal sonography and blood samples were obtained for CA-125 assay before planning surgery, RESULTS: The sensitivity of the sonographic morphologic scoring system was 90.6%, the specificity 84.5%, the positive predictive value 65.9%, and the negative predictive value 96.5%, compared with 68.8, 77.3, 50.0, and 88.2% for CA-125 and 96.9, 66.0, 48.4, and 98.5% for the two tests combined, respectively. Only one case of serous borderline ovarian tumor was missed when the two tests were combined. The sensitivity and mean value of the serum CA-125 increased with the stage of ovarian cancer. CONCLUSION: The combination of sonographic findings with a serum CA-125 assay was more sensitive, but less specific, than sonography or the serum CA-125 assay alone in predicting the malignancy of an adnexal mass. The serum CA-125 level generally reflected the stage of the disease. We think that it is reasonable to check the serum CA-125 only in cases of ovarian malignancy diagnosed by sonography.
