Hepatic phospholipidosis (PL) is one of storage disorders in the liver. Biomarkers (BMs) that reflect progression of PL are very limited. To search for BM candidates for PL, male SD rats was dosed with 150 mg/kg/day amitriptyline for 14 days. Phospholipids in liver and plasma were measured by mass spectrometry. In the results, phosphatidylcholine (PC) (36: 1), PC (36: 4) and PC (38: 5) were increased in liver, and decreased in plasma conversely. It was considered that the decreased phospholipids in peripheral blood might be related to the accumulation of phospholipids in the liver.
