[Enzymatic reaction of the follicular cell population in the human appendix].
Histochemical techniques were employed to determine acid phosphatase and alpha-naphthylesterase activities in follicular cells from the mucosa of surgically removed human appendixes. These very reactive cells are found in two areas: in the middle of the light centre and in the surroundings of this centre. The former are globose, arranged with a certain degree of order, and have a reticular anchorage that does not appear to be particularly affected by the physiological and pathological events that occur in the appendix, whereas those of the border vary in number or may even be absent. They have an elongated shape and are also anchored in a reticulum that in this case is more consistent. The result is that in certain forms of appendiceal disease the pale centre of the follicle is closed in a kind of shell formed of very reactive cells. The identification and significance of these two groups of cells of the light centre are discussed.
