Our present studies of the Cyprinoid spleen are primarily confined to only two varieties of carp, namely, Cyprinus carpio L. and Carassius auratus L. The spleen of both fish is very much the same, being of a single thin layer of epithelium with a thin stratum of fibrous tissues underlying it. The capsule is devoid of muscles and does not have the dense trabeculae extented into its tissues as in the mammals. The chief characteristics of the spleen are the ellipsoids, pulp and melanomacrophage centres.Ellipsoids:...

Our present studies of the Cyprinoid spleen are primarily confined to only two varieties of carp, namely, Cyprinus carpio L. and Carassius auratus L. The spleen of both fish is very much the same, being of a single thin layer of epithelium with a thin stratum of fibrous tissues underlying it. The capsule is devoid of muscles and does not have the dense trabeculae extented into its tissues as in the mammals. The chief characteristics of the spleen are the ellipsoids, pulp and melanomacrophage centres.Ellipsoids: At each of the terminal end of the splenic arteries, it branches into 3 to 4 thick-walled filter capillaries, designated as "ellipsoids" similar to the branching of the brush-artery (a. penicilli) in mammals. The lumen of the ellipsoids is rather narrow. They have a flattened endothelial lining and external to which is a single layer of large macrophages. This macrophage sheath is bounded by a fairly thick fibrous membrane, its lumen finally opens into the pulp lacunae. In the lacunae of the spleen, newly formed blood cells enter into the blood stream. From the lacunae the blood passes into the venous capillaries and venules, and in turn drains into the veins adjacent to the arteries. Since the lumens of the ellipsoids are very narrow and blood cells must pass through them, the degenerating blood cells (especially the erythrocytes) would likely be damaged during their passage and eventually disintegrated. Their hemoglobin, especially the iro nmolecules, are utilized in the formation of new blood cells.The spleen of the Crucian Carp was also examined for their phagocytic properties with colloidal carbon by intraperitoneal injection. Fish are killed at 2,5,24 and 48 intervals h At 2 h. after injection only a small number of macrophages laden with carbon particles were seen within the ellipsoids. At 48 h. there were many macrophages densely packed with carbon particles in the ellipsoids. Electron micrographs showed that in addition to the fine carbon particles there are also numerous round residual bodies observed in the macrophages of the ellipsoids.Splenic pulp: There is no sharp demarcation between white and red pulp; the splenic pulp consists of many blood lacunae without vascular walls. In the lacunae of the spleen there are a large number of red blood cells, lymphocytes and hemopoietic tissues. The newly formed blood cells enter into the blood stream, and passing through the venous capillaries and venules. Imprints of the spleen showed that mature erythrocyte, lymphocytes, thrombocytes and hemocytoblasts are the commonest cellular elements. The granulocytes are also seen though not prominent.Melanomacrophage centres: The melanom acurophage centres are usually located nearavessel, and may often be invested with one or more layers of strands of externa, usually a fine reticular limitting membrane. Autoradiographic studies by Ellis and de Sousa (1974) concluded that replete macrophage may migrate from the ellipsoids to the melanomacrophage centres and suggested that the aggregates of macrophages and melanomacropbages with lymphoid cells in the spleen of the teleost fish might represent primitive germinal centres. According to our observation, the central region of the germinal centres of the lymphoid tissue is filled with immature lymphocytes exhibiting many mitotic figures. When the Crucian Carp are injected with indian ink, the number of melanomacrophage centres increased and are more distinct. It is capsulated with 3 to 4 concentric rings of flattened fibroblast like cells with indistinct central cells, their nuclei collapsed, desolveed and eventually completly disintegrated. In view ow these facts, we incline to believe that the function of the fibrous and the flattened cell capsules of the melanomacrophge centres might also act as a factor to prevent the autolytic products to leak out.

鲤鱼和鲫鱼的脾脏中都没有小梁,其红髓和白髓是混合的。脾脏中都有椭圆体,其末端向脾髓开放。脾髓的纤维网眼中缺乏血管壁,椭圆体毛细血管中的血液可直接流入脾髓网状结缔组织的腔隙中。腹腔注射墨汁的鲫鱼,2小时后即可在椭圆体的巨噬细胞中看到碳粒的积累,可见脾脏的过滤作用主要在椭圆体中进行。在注射墨汁的鲫鱼脾脏中,黑色素巨噬细胞中心比未经注射鱼的脾脏明显,且数量增多,它和哺乳动物淋巴结和脾脏中的生发中心结构和功能都不相同。

Rats were subjected to 15% body surface area third degree burns combined with 2 , 4 , 6 , and 8 Gy irradiation respectively. 48 hours after injury, the DNA and RNA contents of the bone marrow, lymph nodes, spleen and peripheral blood were found to have marked reduction, which became more marked when the dosage of the radiation was increased. Furthermore, it was found that the DNA content decreased more rapidly than the RNA content and the chnage of RNA was more marked in the hemopoietic tissues than in the peripheral blood. Nucleic acid reduction occurred more severely following 2 Gy irradiation than following 15% BSA third degree burns. After the combined iujury of 8 Gy irradiation and burns, th? reduction of nucleic acids in all the above-mentioned tissues exceeded 50%.The mechanism of the changes of necleic acids in the hemopoietic tissues after combined injury of radiation and burns was discussed. Radiation played a more important role than burns in resulting in the reduction but the synergistic effect of burns could not be neglected and could be clearly demonstrated.

大鼠受15%三度烧伤,同时分别复合2、4、6、8戈瑞(Gy)照射。伤后48小时,骨髓、淋巴结、脾脏及外周血中的DNA和RNA含量随照射剂量增加而明显降低。照射以后上述组织中DNA含量减少的速度较RNA减少更快。造血组织中DNA含量的改变比外周血要明显。2Gy照射的核酸改变比15%三度烧伤更严重。8Gy照射复合烧伤后,上述组织的核酸含量减少部超过50%。在放射和烧伤的复合效应中,放射是起主导作用的。但可明显看出烧伤对辐射的叠加效应。文章讨论了放射复合烧伤时核酸改变的机制。

LACA and Shanghai strain mice were transplanted with heterosexal bone marrow cells from normal syngeneic animals,littermates or unrelated donors after whole body γ-irradiation with 9~10 Gy.Recipient animals were sacrificed at various intervals wi-thin one year after bone marrow transplantation and donor type cells in recipient bonemarrow were identified by means of C-banding technique.The results of this experiment show that the decisive factors influencing take andproliferation of donor hemopoietic stem cells in recipient hemopoietic tissues and its long-term replacement for host hemopoietic function are the irradiation dose and the geneticrelationship between donor and recipient.The clinical significance of these results to bone marrow transplantation in patientswith aplastic anemia and acute leukemia is discussed.

LACA系和上海种小鼠于一次全身照射9~10Gy后分别移植正常异性同系、同窝或同种动物骨髓。移植骨髓后一年内不同时间分批活杀动物,借C分带染色识别Y染色体法追踪受体骨髓中供体型细胞所占比例。追踪观察结果表明,决定供体造血干细胞能否在受体造血组织中成活、增殖并长期替代造血功能的因素为照射剂量及供、受体间遗传学关系。本文结合本实验结果,讨论了当前临床上对一些血液病进行骨髓移植时有关照射剂量与方法的问题。
