Abstract
THE lachrymal gland in mammals has acinar tissue leading to ducts lined with columnar epithelium showing no regional differentiation. The Na/K ratio of an established secretion shows no alteration in relation to variation in secretory rates, nor is there other evidence of sodium absorption from the acinar secretion associated with exchange for other ions1. There are no records of experiments on the effect of mineralocorticoids on the sodium–potassium relation of lachrymal secretion. In view of the fact that sheep were available with graded sodium depletion, and therefore proportional aldosterone secretion rate2, saliva and tears were collected for sodium and potassium assay.
