Tin in the thymus gland of dogs

The thymus glands from four mixed breed dogs were analyzed to determine the water content, chloroform extractable fraction and residue. The thymi samples were assayed for tin and compared to the tin in the spleen and muscle tissue. The tin content in the thymus gland (29.4 ppm) was higher than the muscle (14.9 ppm) or spleen (12.8 ppm). The tin content in the lipid portion of the thymus was approximately four times greater than the non-chloroform extractable fraction (primarily protein).
