A 4-year-old cat was referred for a suspected pulmonary mass. True diaphragmatic hernia presence was diagnosed via computed tomography (CT). There was a thin membrane covering the diaphragmatic defect. The membrane was thinner than the diaphragm. After contrast injection, the membrane was less enhanced than that of the normal diaphragm. The membrane was identified as a remnant of the parietal pleura. In addition, contrast-enhanced CT images provided clarity in viewing the herniated liver and falciform fat. A thinner membrane, covering the diaphragmatic defect, and attached to the thicker normal diaphragm, is considered a unique CT feature of true diaphragmatic hernia.

This study was performed to compare the effects of carboxymethylcellulose (CMCE), chondroitin sulfate (Chondron), and carboxymethylchitosan (CMCH) on preventing intraperitoneal adhesion. As a result, the tensile strength of adhesions formed between the parietal peritoneum and the ileal serosa was significantly decreased in the groups of three different kinds of anti-adhesive agents. The distance of adhesion site was slightly increased in the treatment groups comparing control group. In the CMCH group, the inflammatory cell infiltration, collagen hyperplasia, and neovascularization were significantly lower than those of control group. It was observed that the damage at intestinal serosa was significantly decreased in the chondron and CMCH groups comparing control group. Therefore CMCH may be useful as a anti-adhesive agent in the prevention of intraperitoneal adhesion in rats.

개에서 복강수술 후 유착방지에 대한 sodium carboxymethylcellulose (SCMC), oxidized regenerated cellulose (ORC), vitamin E의 병용효과를 알아보고자 본 실험을 수행하였다. 실험견은 대조군, SCMC 처치군, ORC 처치군, SCMC와 vitamin E 처치군, ORC와 vitamin E 처치군의 5개군으로 분류하고 각 군에 5두씩 배치하였다. 정중개복 후 회장 장막에 6 cm 간격으로 5곳에 찰과상을 입혀 유착을 유발했다. 유착장소는 전군에서 장막-장간막(37.6%), 장막-장막(24%), 장막-대망막(8.8%), 장막-복막(3.2%) 순으로 발생하였다. 유착발생빈도는 SCMC와 vitamin E 처치군이 56%로 대조군 92%, SCMC 처치군 84%, ORC 처치군 64%, ORC와 vitamin E 처치군 68%에 비해 낮았다. 유착형성 점수는 SCMC와 vitamin E 처치군에서 다른 처치군에 비해 유의적인 감소를 나타내었다(p < 0.01). 따라서, 복강수술 후 유착방지에 있어 SCMC와 vitamin E의 병용이 개에서 효과적이라고 생각된다.

The development of abomasum in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning and transmission electron microscopy. The results obtained were summarized as follows ; 1. The abomasum wall appeared to be differentiated into the epithelium, lamina propria, muscle layer, and serosa at 60 days of gestation. The epithelium was stratified columnar and these nuclei were located near the apical two thirds portion of the cell at 60 days of gestation, and then transformed into simple columnar epithelium with the flat basal nuclei. 2. The inner circular and outer longitudinal muscle layers were observed at 90 days of gestation and the blood vessels had become quite well developed as various arterioles, venules and capillaries of different size during this age. 3. Gastric pits were seen at 90 days of gestation and continued gradually to increase depth during gestation. 4. The mucous, parietal and chief cells appeared in epithelium at 90 days of gestation and continued gradually to increase in number during gestation. In 120 days fetuses and neonates, muscle layer had become very thickeness. 5. Scanning electron microscopically, the inner surface of the abomasum already consisted of wavy spiral folds which had many fine wrinkles at 60 days of gestation. In 90 day old fetuses, each spiral fold was enlarged and its surface was tended to be split into many straight longitudinal ridges and among these ridge were found shallow grooves, At 120 days, the subdivided swellings of ridges were progressively complicated in shape. In the neonates, the inner surface was flat and holed with many gastric pits. 6. Transmission electron microscopically, the epithelium was straified columnar and these nuclei were irregular shape at 60 days fetus. The parietal, chief and mucous cells were observed in 90 day old fetuses and continued gradually to increase in number during gestation. 7. The development of the abomasum was relatively slow at early stages, it was accelerated greatly in the last of gestation.

랫트에서 melatonin(N-acetyl-5 methoxytyptamine)이 복강 내 유착 형성 방지에 미치는 효과를 알아보고자 본 실험을 수행하였다. 총 42마리의 수컷, Sprague Dawley 랫트를 유착 유도 후 무처치 대조군, 5% ethanol 용액을 투여한 sham군, melatonin 1 mg/kg 처치군(Mel 1군), melatonin 3mg/kg 처치군(Mel 3군), melatonin 10mg/kg 처치군(Mel 10군), melatonin 30mg/kg 처치군(Mel 30군)등 6개 군으로 분류하고 각 군에 7마리씩 배치하였다. 정중개복 후 맹장을 확인하고 맹장에서 0.5cm지점의 오름 결장에서 시작하여 3cm 간격으로, 장간막 반대측 장막 5곳에 $0.5{\times}1cm$크기로 찰과상을 생성하여 유착을 유도하였다. 대조군은 어떤 처치도 없이 복강을 폐쇄하였으며 sham군은 5% ethanol 1ml, 나머지 군은 각각의 용량에 맞춰 5% ethanol 에 녹인 melatonin용액 1 ml를 복강 폐쇄 전 주입하였다. 수술 2주 후에 유착발생빈도 및 정도를 평가하였다. 유착장소는 전군에서 장막-장간막(25.7%), 장막-장막(21%), 장막-대망막(5.7%)순으로 발생하였다. 유착발생빈도는 Mel 10군이 17.1%로 대조군 68.6%, sham군 91.4%, Mel 1군 57.1%, Mel 3군 60.1%에 비해 낮았다. 그러나 Mel 30군은 20%로 유의적인 차이를 보이지 않았다. 유착형성은 대조군, Sham군, Mel 1군, Mel 3군, Mel 10군, Mel 30군에서 각각 $264.7{\pm}140.2,\;378.9{\pm}153.2,\;116.1{\pm}94,\;29.4{\pm}30.3,\;45.1{\pm}44$로 Mel 10군과 Mel 30군이 유의적인 감소를 보였으나(p<0.05) 이들 두 군 간의 차이는 나타나지 않았다. 이상의 결과로, 랫트에서 복강수술 후 melatonin 10mg/kg투여가 복강 내 유착 방지에 효과적이라고 생각된다.

개에서 hyaluronic acid(HA), vitamine E 및 두 약물의 병용이 복강수술 후 유착방지에 미치는 효과를 비교하고자 본 실험을 실시하였다. 실험견은 HA 처치군, Vitamin E 800 처치군, HA와 Vitamin E 800 처치군 그리고 HA와 Vitamin E 1600 처치군의 5개군으로 분류하고 각 군에 3두씩 배치하였다. 정중개복 후 회맹연접부를 확인하고 회장 쪽으로 5cm 간격으로 5곳에 1$\times$1cm 크기로 찰과상을 유도하였다. HA는 0.1%로 하나의 찰과상 당 3ml과 복강 내에는 체중 당 3ml을 도포하였다. Vitamin E 는 수술 전 5일부터 수술 후 14일까지 800, 1600IU의 용량으로 경구투여 하였다. 수술 3주 후에 유착발생빈도 및 정도를 평가하였다. 혈액학적 검사소견 상 WBC의 수치는 수술 1일 후 전군에서 최고치를 나타냈으나 4일 후부터는 감소하기 시작하여 14일에는 정상범위로 회복하였으며 전군에 있어서 유의적인 변화는 나타나지 않았다. Fibrinogen 수치는 수술 1일 후 전군에서 최고치를 나타냈으나 4일 후부터는 감소하기 시작하여 7일에 수술전 수치로 회복하였으며 전군에 있어서 유의적인 변화는 나타나지 않았다. 유착발생 장소는 장막-장간막(43.3%), 장막-장막(20%), 장막-대망막(5%), 장막-복막(1.7%) 순으로 발생하였다. 유착발생빈도는 HA와 Vitamin E 800 처치군 47%로 Vitamin E 800 처치군 100%, HA 처치군 80%, HA와 Vitamin E 1600 처치군 53%에 비해 낮았다. 유착형성은 HA처치군, Vitamin E 800 처치군, HA와 Vitamin E 800 처치군 그리고 HA와 Vitamin E 1600 처치군에서 5.3$\pm$0.58, 7$\pm$1.00, 2.3$\pm$1.15과 3$\pm$1.00로 HA와 Vitamin E 800 처치군이 유의적인 감소를 보였다(p<0.05). 이상의 결과를 종합하면 복강수술 후 유착방지에 있어 HA와 800 IU Vitamin E 병용투여가 효과적이라고 사료된다.

The present study was designed to investigate the morphological developments of the stomach in the prenatal and postnatal rats. The gastric fundus of 16- to 22-day-old fetuses, neonates, 7-day-old, 14-day-old, 21-day-old, and adult rats were observed by light and scanning electron microscopy. Light microscopic studies. 1. In the 16-day-old fetuses, the walls of the gastric fundus were differentiated into epithelium, lamina propria, muscle layer, and serosa. The lamina propria was composed of mesenchymal connective tissue cells with sparse nucleus and their fibers. 2. In the 17-day-old fetuses, the muscular layer were differentiated into the circular and longitudinal muscle layers. 3. The epithelium on the fundus of stomach was stratified columnar cells at 16-, 17- and 18-day-old fetuses, but partly converted into simple columnar epithelium at 19-day-old fetuses. 4. The mucous cells were positive by PAS reaction at the 19-day-old fetuses and then these developed rapidly within 1 or 2 days before birth. 5. In the 20-day -old fetuses, the parietal cells were distinguished from other type cells and these cells were chiefly crowded in the middle parts of the gastric glands after 7-day-old. Scanning electron microscopic studies. 6. The surface of gastric mucosa was covered with forms of the various protrusions by forming villi at the last few days before birth and these protrusion forms were fused and folded each other. 7. The mucosal surface was closely packed by polygonal mucous cells. The openings of gastric glands were seen as slit-like round invagination and were more numerous and increased gradually in depth after the postnatal life. The above findings indicate that prominent changes occurred in the pattern of cellular proliferation in the stomach fundus at the end of gestation. The gastric epithelium had well-defined glands composed of parietal, chief and mucous cells just before the birth. The stomach fundus, therefore, were developed morphologically as those of normal adult at fourteen days after birth.
