[The evidence of POZ on the xenogenic transplantation of skin (author's transl)].

Phenoloxidase containing cells (POZ) identified with histochemical techniques in the subcutaneous connective tissue showed a marked increase in their number in response to heteroplastic skin transplantation in the rat. The number of these cells reached a peak of the 6th day of transplantation. From this time on their number gradually decreased on the 14th as well. POZ never invaded the graft, they remained confined to the host's tissue. A similar proliferation of POZ was never observed in the vicinity of skin autografts. The possible role in immune reactions of these cells is discussed.

[The occurrence of phenoloxidase containing cells (= POZ) during the embryonary development of the hen (POZ-cells of the immunological system?) (author's transl)].

By means of the phenoloxidase reaction it would be shown that the POZ appear in haemopoetic cell islands of the yolk sac being hatched 6 days and being hatched 11 days, they appear in embryonary tissues. Favoured target organs are the spleen and the bone marrow, though also at the same time can be seen some cells in the connective tissue of the embryo. POZ can also be found in the bursa of FABRICIUS. The participation of the POZ in immunological reactions is supposed.

Structure of the osteocyte capsule in rats with hypervitaminosis-D and rickets.

A histochemical and topo-optical study was made of the changes of the osteocyte capsule (OC) of the cortical and spongious bone layers of the tibia and vertebra of rats with hypervitaminosis-D and rickets. In hypervitaminosis-D the number of stained OCs was found to decrease. After treatment with high doses of vitamin D, a broadening of the OCs was noted in the area of demineralizing bone. Under the polarization microscope a decrease occurred in the proportion of birefringent OCs, more marked in birefringence than in staining. Since bone demineralization due to vitamin D was not followed by a rise in the number of osteoclasts, it is concluded that osteocytic activity has an important role in demineralization as shown by the broadened OC. In rachitic rats considerably fewer OC took the stain and showed birefringence than in the controls. Thus, alteration of the OC structure disturbs the nutrition of bone tissue and thereby aggravates the pathological process.
