FTY720 Effects on Inflammation and Liver Damage in a Rat Model of Renal Ischemia-Reperfusion Injury

Table 1

Tissue sections, stained with hematoxylin and eosin, were assessed using an established scoring system. Lesions observed within the section were graded by the percentage of the section affected by the lesion as well as by the number of foci observed as follows.

Grading scheme for focal and multifocal lesions
Severity	Percent of the sections affected	Grade	Quantifiable finding
Normal	0%	0	No foci
Minimal	<5%	1	1-2 foci
Mild	5-25%	2	3-6 foci
Moderate	25-50%	3	7-12 foci
Marked	50-75%	4	>12 foci
Severe	75-100%	5	Diffuse
