2.5 Measurement of Thymus and Spleen Indices

Twenty-four hours after the last dose, weigh the mice, euthanize them by spinal dislocation, dissect out the thymus and spleen, and weigh them. Calculate the thymus and spleen indices using the following formulas:

Thymus index (mg/10 g) = Thymus weight / (Final mouse weight - Tumor weight) × 10

Spleen index (mg/10 g) = Spleen weight / (Final mouse weight - Tumor weight) × 100
