It has been known that the hemolymph node is one of the lymphoid organs found normally in ruminants and some rodents, and this organ shares morphological and functional characteristics of lymph node and spleen. To clanify the rigorous definition of morphological structures and functions of the hemolymph node in Wistar Kyoto(WKY)rats, we examined these organs of WKY rats gross anatomically and light microscopically. The hemolymph nodes were normally found in the abdominal cavity and in the neck of WKY rats. This organ was surrounded by a thin connective tissue capsule and there was a hilus. The parenchyma comprised a cortex of lymphatic nodules and diffuse lymphatic tissues, and a medulla of diffuse lymphatic tissues arranged in cords. Afferent and efferent lymph vessels were observed but there was no extensive subcapsular and medullary sinuses. These sinuses were filled with erythrocytes. The stroma of hemolymph nodes was composed of reticular cells and fibers, and many lymphocytes, granulocytes, erythrocytes, plasma cells, macrophages and megakaryocytes were supported by the reticular network. The above findings suggest that the hemolymph nodes of WKY rats may take part in blood formation, blood filtration and immune reaction.

It has been known that the hemolymph node is one of the lymphoid organs found normally in ruminants and some rodents, and this organ shares morphological and functional characteristics of lymph node and spleen. To clarify the rigorous definition of morphological structures and functions of the hemolymph node in Sprague-Dawley(SD) rats, we examined these organs of SD rats gross anatomically and light microscopically. The hemolymph nodes were normally found in the abdominal cavity and in the neck of SD rats. This organ was surrounded by a thin connective tissue capsule and there was a hilus. The parenchyma comprised a cortex of lymphatic nodules and diffuse lymphatic tissues, and a medulla of diffuse lymphatic tissues arranged in cords.

영남대학교 의과대학 부속병원에서 1991년 1월부터 1998년 6월까지 20례의 자궁육종을 경험한 결과 자궁육종 환자의 연령별 분포는 24세에서 71세이었고 평균 연령은 50.2세였고 평균 분만 횟수는 3.7회였다. 병기는 1기가 9례(45.0%), 2기가 1례(5.0%), 3기가 6례((30.0%), 4기 가 4례(20.0%)이었으며 병기에 따른 생존율에는 유의한 차이가 없었으며, 병리조직검사상 자궁평활근육종이 13례(65.0%), 악성 혼합 뮬러씨 종양이 5례(25.5%), 기타 횡문근육종 1례, 맥관육종 1례로 조직검사에 따라서도 생존율의 차이를 보이지 않았다. 주된 임상증상으로는 부정기적 질출혈이 7례(35.0%), 하복부동통이 5례(25.0%), 비정상 복부종괴가 5례(25.0%)였다. 조직학적 소견상 10 HPF당 유사분열수가 6-10개인 경우가 2례, 10-15개인 경우가 3례, 16-20개인 경우가 2례, 20개 이상인 경우가 2례였으며 이들 유사분열수와 생존기간과의 관계는 조사할 수가 없었다. FIGO 병기 1기의 중앙생존기간은 27.0개월이었고 3기는 23.5개월, 4기는 3.0개월이었으며 2기는 산출이 불가능하였고 이들 병기와 생존기간과는 유의한 차이가 없었다. 치료 방법으로는 수술적 방법, 화학요법, 방사선 요법을 실시하였으며 수술적 방법으로는 전자궁 및 양측 부속기 절제술이 15례 (75.0%), 전자궁 및 단측 부속기 절제술이 3례(15.0%), 근치적 자궁적출술이 1례였다. 치료결과 6명이 사망하였고 7명이 생존해 있는데 모두 무병상태로 추적 관찰중이며 나머지 7명은 추적이 불가능하였다. 추적조사를 위한 지표로서 CA-125가 5례에서 사용되었는데 그중 2례(40.0%)에서 현저한 증가를 보였다.

A desmoid tumor is a locally aggressive growth of connective tissue origin which infiltrates the surrounding tissue and has a marked tendency for recurrence. And so it was also called as an aggressive fibromatosis, musculofascial fibromatosis or fibrosarcoma etc. Thirteen cases of desmoid tumor was treated since 1980, and their retrospective study was done with 79 months of follow-up after initial surgical excision. The female was involved in 12 cases(one male) with the age ranged from 7-50 years, average 28 years, and seven patients in third decade. A slowly growing mass was excised on average 4 months after first notice of the mass, but their margins are not demarcated clearly in most cases. Wide excision in 12 cases was done, but wide excision and saphenous vein graft was performed in one case because of invasion of posterior tibial artery by tumor mass. The tumor was found on extraabdominal region in 8 cases(61.5%) but 5 cases in abdominal wall(38.5%). The recurrence rate was high(6/13, 46.2%), and 11 times in 6 patients were recurred(average 1.8 times), within 27 months of initial excision. Six cases of recurrence were treated with wide excision again in 3 cases, wide excision combined with radiotherapy(4,000-6,000cGy) in 4 cases and wide excision with chemotherapy in one case. During the follow-up for average 21 months after treatment, no recurrences are found. Tumor remission periods without recurrence are average 67 months in all, and 11 years in longest case. Histologically it was very mimic with fibrosarcoma but could be differentiated with Trichrome stain, and their findings are not changed after recurrence.
