Megjegyzések:	Background: In our experiments, we wished to prove - using mini-PET, autora- diography and organ distribution examinations - that rat hepatocarcinoma (He/De), and mesoblastic nephroma (Ne/De) cells give metastases to the parathy- mic lymph nodes. Material and methods: 106 He/De or Ne/De cells were placed under the capsule of the left kidney. Two weeks after implantation, control and tumor-bearing rats were anesthetized and a radioligand, 18FDG (15.0 MBq), was injected i.v. For autorad- iography, 60 ?m thick cryostate sections (Leica cryomacrotome) were cut and ex- posed to phosphor imaging plates. Results were expressed in intensity pixel units. For organ-distribution, different tissues were removed and their activities were mea- sured. The radioactivity of the samples was used to determine the differential ab- sorption ratio (DAR). Results: By taking the pixel density of resting striated muscle as one unit, the rela- tive pixel densities were in decreasing order: 14.23 in He/De tumor, 10.82 in par- athymic lymph nodes, 5.36 in kidney, 2.35 in blood and 1.57 in liver. In the case of the Ne/De, the results were the same. The DAR values also showed that the majority of the radioactivity was accumulated in the tumors and in the parathymic lymph nodes. Conclusions: From the autoradiographic, phosphor image and tissue distribution experiments, we concluded that He/De and Ne/De tumors grown under the cap- sule of kidney represent a significant metastatic burden manifested primarily in parathymic lymph nodes. The renal capsule and parathymic lymph node complex seems to be suitable for the isolated in vivo examination of metastatic development and for the detailed analysis of secondary tumors.
