    Notes: Summary Sterile fragments of cellophane, cat-gut, cotton, or beef muscle implanted into the body cavity of Locusta migratoria and Melolontha melolontha are immediately surrounded by granular hemocytes which form a multi-layered capsule around each foreign body. The cytoplasm of the granular hemocytes of the outer zone of the capsule in both species shows an accumulation of fibrous material (microtubules and microfilaments). None of the implanted material appeared to be degraded.

    Notes: Summary Of the three hemocyte types present in the blood of Calliphora, only one participates in capsule formation around implanted cellophane. This hemocyte, the thrombocytoid, shows in the blood a tendency to dissociate into numerous small cytoplasmic fragments, comparable to the mammalian megakaryocyte. This tendency is dramatically increased during the process of encapsulation. Most of the intact thrombocytoids and the numerous fragments participating in capsule formation do not show any particular modifications in their cytoplasm during this process, which corresponds to a mere sequestration of the implant. Dense material, resulting from necrotic cell debris and hemolymph lipoproteins, is often observed between the cellophane and encapsulating thrombocytoids, which apparently participate in the resorption of this material.
