Dry environment on the expression of lacrimal gland S100A9, Anxa1, and Clu in rats proteomics.

Aim: To investigate the underlying mechanism of dry environment (autumn dryness) affecting the lacrimal glands in rats.

Methods: Twenty Sprague-Dawley rats were randomly divided into two groups. The rats were fed in specific pathogen free environment as the control group (=10), and the rats fed in dry environment as the dryness group (=10).
