This study aimed to differentiate gastric mucosal lesions such as the inflammatory gastric mucosa, gastric dysplasia and adenocarcinoma, using the CEA(carcinoembryonic antigen), AgNORS(Nucleolar organizer regions) and PCNA(proliferating cell nuclear antigen) stains. The tissue samples were taken from 30 cases of inflammatory gastric mucosa (19 gastritis and 11 regenerative hyperplasia), 28 cases of gastric dysplasia (9 mild dysplasia, 10 moderate dysplasia and 9 severe dysplasia) and 21 cases of gastric adenocarcinoma. The CEA was expressed in 16 of 21 adenocarcinomas(76%), but in neither inflammatory nor dysplastic gastric mucosae. The mean number of AgNORs per nucleus was 1.54 in inflammatory gastric mucosa, 1.80 in gastric dysplasia, and 1.88 in adenocarcinoma. The number of AgNORs was increased in dysplasia and adenocarcinoma compared to the inflammatory gastric mucosa without statistical significance. The percentage of the PCN A positive cells was 35.2% in inflammatory gastric mucosa, 44.1 % in gastric dysplasia, and 69.0% in gastric adenocarcinoma. The positivity of the PCNA was significantly increased in adenocarcinoma compared to the inflammatory gastric mucosa and dysplasia. In conclusion, the frequency of the CEA positive staining was increased in the gastric adenocarcinoma, and so CEA stain will be able to provide an additive method for the differential diagnosis between severe dysplasia and adenocarcinoma of the stomach.

OBJECTIVES: To evaluate the effect of parity & delivery method on female fecal incontinence. METHOD: Based on 213 cases of 4 different delivery method and 40 cases of one non-delivery group, a retrospective analysis of the prevalence of female fecal incontinence, between January 1996 and December 1998, was done. With delivery mode, 4 different groups were: first vaginal delivery group , two or more vaginal deliveries group, first cesarean section group, and first vaginal delivery followed by cesarean section group. All subjects were examined by questionaire or phone about the experience of fecal incontinence after delivery. In cases of fecal incontinence , we reviewed the obstetric complications with medical records. RESULT: There was no fecal incontinence in the non-delivery group. The incidence of fecal incontinence in the two or more vaginal delivery group(11.7%, 9/77) and the first vaginal delivery followed by cesarean section group(18.1%, 8/44) was higher than the first vaginal delivery group(6.8%, 3/44), and the first cesarean section group(2.1%, 1/48)(P<0.05). The obstetric complications in fecal incontinence cases were: a prolonged second stage, anal sphincter laceration, vacuum extraction, a large baby etc. CONCLUSION: Fecal incontinence was significantly correlated with the number of vaginal deliveries and obstetric complications during delivery. Fecal incontinence after the first vaginal delivery or vaginal delivery followed by cesarean section are very important factors in choosing the next delivery method.

This study was designed to evaluate the expression of non-collagenous protein in periodontal tissue during the experimental movement of rat incisors, by LSAB(labelled streptavidine biotin) mmunohistochemical staining for osteonectin and osteocalcin. Twenty seven Sprague-Dawley rats were divided into a control group(3 rats) and 6 experimental groups(24 rats) where 75g of force was applied from helical springs across the maxillary incisors. Rats of experimental groups were sacrificed at 12 hours, 1, 4, 7, 14 and 28 days after force application, respectively. And the tissues of a control group and experimental groups were studied immunohistochemically and histologically. The results were as follows: 1. Until 28 days after force application, periodontal fibers had been strectched on tension side and compressed in pressure side of all the experimental groups, and the arrangement of periodontal fibers had not been recovered yet. 2. The expression of osteonectin in control group was rare in dentin, cementum and osteocyte, and was mild in odontoblasts and matrix of alveolar bone. 3. The expression of osteocalcin in control group was negative in gingiva, osteoblasts, osteocyte and cementum, and was rare in predentin, capillaries in pulp and periodontal ligament and the matrix of alveolar bone. 4. There was no difference in the expression of osteocalcin or osteonectin in dentin, cementum, pulp, odontoblasts, between of control and of experimental groups. 5. The expression of osteonectin in intermaxillary suture got the peak in 7-day and was declined after 14-day. The expression of osteocalcin remained in a same degree since it became mild in 14-day. 6. The expression of osteonectin in pressure side of periodontal ligament of experimental group was rare, which was similar to control group. But in tension side, it wr , increased until 14-day aftrer which it was declined. 7. The expression of osteocalcin in periodntal ligament was rare in 12-hour to 14-day, but became severe in 28-day, which was greater in tension side than in pressure side, and in the periodontal. fiber next to alveolar bone than tc tooth surface. 8. The expression of osteocalcin in alveolar bone was rare until 14-day in pressure side, but became moderate in 28-day. The expression of osteonectin was increased from 7-day by time dependency, which was greater in tension side than in pressure side.

There are many difficult problems and various methods in the treatment of difficult fractures of the femur. We reviewed the records of twelve patients who had been managed with circular external fixation using the llizarov apparatus for difficult fractures of the femur at Keimyung University. Dongsan rnedical center from October 1993 to April l996. There were ten males and two females with an average age of 42 years (range, 16-74 years). Si.x of twelve patients were severely comminuted supracondylar and intercondylar fractures of the femur associated with severe soft tissue injury (including four open fractures). These patients were treated initially by closed reduction with Ilizarov external fixator and followed by compression-distraction techniques. Four of the remaining six ptients developed infected non-unions after internal fixation of the femur without shortening or bone defect. These infected non-unions were treated by curettage, irrigation and Ilizarov application. After the control of infection, compression - distraction techniques were applied. One of the remaining two patients had severe open comminuted fracture of the supra-intercondyle region of femur associated with diaphyseal segmental bone defect (5cm in length). This patient was treated with closed reduction and internal bone transportation usipg llizarov external fixator. One patient with varus deformity (20 degree) was treated by correction of the deformity and simple compression technique. In three patients, additional autogenous cancellous iliac bone graft was done. The union of the fracture site was obtained in ten patients and the duration of llizarov external fixation was an average of 10 months (range 6-14 months). We experienced several complications; there were twelve patients of limitation of motion of knee, ten patients of pin tract infection, one patient of fracture site non-union, one patient of re-fracture and one patient of femoral artery injury. We concluded that the Ilizarov external fixation technique is one of the effective methods for the treatment of difficult fractures of the femur in spite of its complexity and high incidence of complications.

A 42-year-old woman with systemic lupus erythematosus (SLE) has had wide-spread erythemas with some purpuric patches on her trunk and upper extremities during exacerbation of her disease. Biopsy findings from erythematous lesions and purpuric areas revealed the pathology of lupus erythematosus and leukocytoclastic vasculitis (LCV) with immune deposits, respectively. A feature of wide-spread symmetrical erythemas with foci of LCV occurring in this patient is considered to be an unusual presentation.

To investigate the effect of hyperoxia on EKG findings and to evaluate the applicability of EKG as noninvasive monitoring index of oxygen toxicity, 38 rabbits were continuously exposed to 6 different conditions-3 hyperbaric oxygenations (HBO-2.5, 3.5 and 5ATA, 100% O2), normobaric oxygenation (NBO, 100% O2), hyperbaric aeration (HBA-5ATA, 21% O2) and normobaric aeration (NBA, 21% O2)-for 120 minutes and their EKG and time to dyspnea and convulsion were recorded. Dyspnea and death were observed in exposure conditions of HBO-3.5 and HBO-5 (Positive rate of dyspnea; 10%, 100%, death; 10%, 25%, respectively) only, and convulsion in 4 oxygenation groups (NBO; 20%, HBO-2.5; 20%, HBO-3.5; 20%, HBO-5; 88%). Abnormal EKG findings included arrhythmia and ST-T changes and the incidences was increasing with doses(partial pressure of oxygen). In addition to EKG change, findings observed during exosure were dyspnea and convulsion in the order of appearence and when non specific ST-T change was accepted as positive (abnormal) finding, the frequency of abnormal EKG was statistically significant(p<0.01), but when it was excluded from positive results, the frequency of EKG change was not significant(p>0.05). These results suggest that the effect of hyperoxia on heart is myocardial ischemia and arrhythmia, that oxygenation more than 3.5ATA causes myocardial damage in 120 minutes exposure, and that EKG is valuable as monitoring index of oxygen toxicity.

Uterine didelphys with unilateral hematometra, hemicolpos, and ipsilateral renal agenesis is a rare m01lerian duct malformation. Uterine didelphys with an obstructed hemivagina is frequently associated with renal agenesis, mostly ipsilateral to the blind vaginal pouch. Accurate early diagnosis and septal resection elevate pregnancy rate and birth rate but it is difficult to find these malfomations until the complication associated with pregnancy was developed. We report a case of successful gestational outcome in the presence of preterm labor due to hematometrocolpora caused by uterine didelphys with unilateral imperforated vagina and ipsilateral renal agenesis with brief review of the literatures.
