Spleen, liver and thymic indexes of healthy mice treated i.p. with the S.e. nigrum spinosum extract at a dose of 800 mg/kg.

Index	Splenic	Hepatic	Thymic
CONTROL	0.0048 ± 0.0004	0.0672 ± 0.0083	0.0013 ± 0.0002
S.e. nigrum spinosum	0.0059 ± 0.0011	0.0689 ± 0.0079	0.0012 ± 0.0002
ARA-C	0.0039 ± 0.0004*	0.0629 ± 0.0056	0.0009 ± 0.0002*

The organ indexes were determined as the ratio of the organ weights to the body weight. The data are represented as the means ± SDs and are representative of 20 mice per treatment.

^*Indicates a significant difference (Tukey’s test, p ≤ 0.05).
