Table 4. Hepatic number of macrophages before and 12 hours after lipopolysaccharide (LPS) challenge horses and ponies fed placebo or green tea and curcuma extract (GCE).

Values are presented as absolute numbers and percentages of the subpopulation. Grade 0 = no macrophages, grade 1 = 1-33 macrophages, grade 2 = 34-66 macrophages, grade 3 = 67-100 macrophages.
