[Lacrimal glands of dogs and cattle in the light of histologic and histochemical findings].

The secretion of the lacrimal glands and the glands of the third eyelid of dogs and cattle contain neutral polysaccharides, sialic acids, chondroitin sulfate acids A,B and C. In dogs the secretory cycle including the phase of hydratation occurs inside acinuses in the cattle the phase of hydratation takes place in excretory ducts. The stroma of the eye orbit glands contains a great amount of active plasmocytes providing the secretion with immunological activity.
