Figure 6From: Underlying mechanisms involved in the decrease of milk secretion during Escherichia coli endotoxin induced mastitis in lactating miceInfluence of LPS on the amount of milk components released into mammary glands. The concentration of triglycerides (A) and lactose (B) in extracts from mammary glands non-treated (0 h) and at 3, 6, and 12 h after LPS injection were measured by the methods described in the Materials and Methods section. Beta-casein in the extracts was detected by western blotting (C). The β-casein bands were quantified by densitometry analysis (D). Data represent the mean (SD) (n = 8 for measuring triglycerides, n = 4 for measuring lactose, n = 6 for measuring β-casein). *, p < 0.05; **, p < 0.005 vs. 0 h.Back to article page
