Abstract:
Pacinian corpuscles from cat mesentery were fixed in Carnoy's fixative, paraffinsectioned and stained in Feulgen reagent and methyl green-pyronin. Controlled sectionswere hydrolyzed in 20% perchloric acid at 70℃ and 10% perchloric acid at 1-4℃. Itwas found that the so-called nuclei in the lamellae were Feulgen positive and stainedbluish purple after the methyl green-pyronin method. They disappeared after perchloric acidhydrolysis in 70℃ and showed no change after cold treatment. Their histochemicalreactions, stainability and detailed structures were similar to the nuclei of the connectivecells next to the corpuscle. It was therefore concluded the nuclear like bodies in the Paciniancorpuscles studied were true nuclei as mentioned in histological textbooks and not merely thecondensation of fibrils as W. Schwarz recently claimed after electron microscopic observation.These nuclei were located in between the fibrils of the lamellae.
