Accumulation of Calcium 45 by Salivary Glands

Abstract

Conclusion

1. Ca⁴⁵ accumulation and loss in the submaxillary gland is much slower than in the kidney. Equilibrium between the gland and blood is reached approximately 4 hours after administration, while at 8 hours the specific activity of calcium in blood and kidneys has fallen to less than one-half that in the submaxillary gland. Equilibrium is again reached at 18 hours. 2. In female Long-Evans rats, total calcium in the submaxillary gland was 21.6 + 1.0 meq/kg, in the kidney 4.0 + 0.1 meq/kg and in blood 3.66 + .14 meq/kg.
