A novel titanium rabbit ear chamber for vital microscopy of bone tissue

Seventy-eight small titanium-glass culture chambers of own design for vital microscopy of bone tissue were inserted in the ears in 41 rabbits. After insertion without removing the cartilage on the inner side of ears not previously operated upon, 44 out of 56 chambers (79 per cent) became vascularized. It proved satisfactory for bright field, fluorescence and polarized light microscopical observations of living bone tissue for half a year or longer.
