The renal and branchial heart appendages of Sepia officinalis L. were investigated in order to elucidate a possible involvement of their excretory epithelia in hemocyanin metabolism. Immunocytochemical findings and tracer experiments indicate that after passing the barrier of ultrafiltration the hemocyanin molecules are taken up by the epithelial cells of the renal and branchial heart appendages and are subsequently carried back to the circulatory system, suggesting a mechanism of hemocyanin recycling. Apart from a function in maintaining constant hemocyanin levels, the present study indicates that the renal and branchial heart appendages are also sites of temporary hemocyanin storage.
为了阐明乌贼墨囊和鳃心附属器的排泄上皮细胞可能参与血蓝蛋白代谢的情况，对乌贼（Sepia officinalis L.）的肾和鳃心附属器进行了研究。免疫细胞化学研究结果和示踪实验表明，血蓝蛋白分子在通过超滤屏障后，被肾和鳃心附属器的上皮细胞摄取，随后又被带回循环系统，这表明存在血蓝蛋白循环机制。除了具有维持血蓝蛋白水平恒定的功能外，本研究还表明，肾和鳃心附属器也是血蓝蛋白的临时储存部位。
