泪液中含有多种蛋白质，泪液是由眼眶腺的分泌物组成的。由于有间接证据表明，在胆碱能刺激下，泪腺可以分泌蛋白质，因此人们一直认为这些蛋白质是泪腺的来源。在本研究中，测定了泪腺液中蛋白质的浓度，即直接从泪腺的主要排泄管收集的液体，未被其他眼眶腺的分泌物污染。泪腺液流速在2 ~ 10微升/min时，泪腺液蛋白浓度高于血浆蛋白浓度；泪腺液流速小于2微升/min，泪腺液流速大于10微升/min时，泪腺液蛋白浓度与血浆蛋白浓度相同。
A variety of proteins have been identified in tears, which are composed of secretions from all the orbital glands. It has been assumed that the lacrimal gland was the source of these proteins because there is indirect evidence that the lacrimal gland can secrete protein in response to cholinergic stimulation. In the present study, the concentration of protein was determined in lacrimal gland fluid, i.e., the fluid collected directly from the main excretory duct of the lacrimal gland, uncontaminated by secretions from the other orbital glands. The concentration of protein in the lacrimal gland fluid was higher than that in plasma at lacrimal gland fluid flow rates between 2 and 10 microliter/min, but it was the same as plasma at flow rates slower than 2 microliter/min and faster than 10 microliter/min.
