DISTRIBUTION OF ESTERASE IN EPITHELIAL AND LYMPHATIC TISSUES OF THE RABBIT APPENDIX

Abstract
The distribution of esterase activity was studied in relation to the histology of the appendix. Phenyl benzoate was used as substrate. Maximal activity was found in the epithelium covering one surface of the lymphatic nodules. Esterase activities of the components of lymphatic tissue are tabulated; the esterase value for epithelium was 1.5-1.8 [mu]moles of phenol liberated from phenyl benzoate per mm3 of tissue in 30 minutes at 30[degree]C. This value is close to the value for stomach foveolar cells.
