Histological Structures of Several Internal Organs in Racoon Dogs

Samples of several internal organs including kidney,testis,adre- nal glands and pancreas of five healthy adult male racoon dogs were fi- xed in bouin's solution,paraffinwax sliced and stained with hemat1o- xylin and eosin,then the samples were observed microscopically.The results revealed histological features different from other mammals. Ganglions and nerve fibres were well developed in adrenal capsulae.There was an apparent interband between the arch and bundle areas.Large quantity of plasmacytes were seen in adrenal medulla,renal and testical mesenchyma.A tunica vasculosa was clear- ly seen under testieal albuginea.In convoluted tubules there were nu- merous supporting cells which had typical configurations.The medias- tinum testis,being limited to the head,was thin and incomplete Lang- erhans'islands were much more distributed in deep tissues of the pan- creas.
