Analyses of bronchoalveolar lavage fluid (BALF) in MRL-lpr/lpr mice.
We performed bronchoalveolar lavage (BAL) in MRL-lpr/lpr (MRL/l) and MRL- +/+ (MRL/n) mice and evaluated various cellular and humoral components of the bronchoalveolar lavage fluid (BALF) to clarify the pathogenic mechanism of pulmonary fibrosis in MRL/l mouse. The numbers of macrophages, neutrophils and lymphocytes, N-Acetyl-beta-glucosaminidase (beta-NAG), and fibronectin increased in the BALF from MRL/l mice than that from MRL/n mice, but no significant differences were observed in total protein, beta-glucuronidase, acid phosphatase, or phospholipid level. Increased fibronectin level in the BALF from MRL/l mice may be related with pathogenesis of pulmonary fibrosis.
