Sialic acid in rabbit lacrimal gland fluid. 1976

J Kreuger, and N Sokoloff, and S Y Botelho

To date, there has been no attempt to determine which of the orbital glands contribute the sialic acid, which has been found in tears and tear mucoids. In the present study, sialic acid was found in the fluid collected directly from the lacrimal gland excretory duct, uncontaminated by the secretions of the other orbital glands (Nictitans, Harderian, conjunctival) as well as in the fluid secreted into the conjunctival sac by the other orbital glands, uncontaminated by lacrimal gland fluid. At all flow rates, the rate of secretion of sialic acid increased as flow rate increased in both fluids and the rate of secretion of sialic acid by the lacrimal gland was three times that by the other orbital glands. This is the first demonstration that a substance, which can be derived from either nonserum glycoproteins, such as the tear mucoids, or alpha-globulins, is a component of the secretions of the lacrimal gland, as well as of the secretion of the other orbital glands.

D010277	Parasympathomimetics	Drugs that mimic the effects of parasympathetic nervous system activity. Included here are drugs that directly stimulate muscarinic receptors and drugs that potentiate cholinergic activity, usually by slowing the breakdown of acetylcholine (CHOLINESTERASE INHIBITORS). Drugs that stimulate both sympathetic and parasympathetic postganglionic neurons (GANGLIONIC STIMULANTS) are not included here.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012636	Secretory Rate	The amount of a substance secreted by cells or by a specific organ or organism over a given period of time; usually applies to those substances which are formed by glandular tissues and are released by them into biological fluids, e.g., secretory rate of corticosteroids by the adrenal cortex, secretory rate of gastric acid by the gastric mucosa.
