TABLE 2.

Histopathological scores assigned to the focal lesions observed in the brains, livers, and kidneys of mice treated with saline (control), POS, GM-CSF, or the combination of POS and GM-CSF

Organ	Focal lesion score for mice treated witha:
	Saline	POS	GM-CSF	POS-GM-CSF
Brain	1.50 ± 0.22	1.48 ± 0.22	0.84 ± 0.16	1.59 ± 0.28
Liver	0.11 ± 0.06	0.21 ± 0.08	0.30 ± 0.09	0.08 ± 0.05
Kidneys	1.43 ± 0.20	1.56 ± 0.21	1.32 ± 0.23	1.15 ± 0.22

^aAll values are expressed as the means ± standard errors of means of the focal lesion scores for each organ. Lesion scores were calculated as described in Materials and Methods. Data were analyzed by the Kruskal-Wallis ANOVA with Dunn's posttest for multiple comparisons. No significant differences were seen among the treatment groups.
