[Effect of a decoction of six ingredients with rehmannia on the periodontal tissues of animals with kidney diseases].

In this paper, Kidney Yin and Yang deficiency animal models were made by the medicine (hydrocortisone, thyroxin). At the same time the occlusal trauma was accompanied. It was caused by means of corprophagy (microorganism) fed and artificial damage. The authors observed the injuries and effects of the local and systemic factors caused on the periodontal tissues of rats. From the experiment the authors found the injuries of the periodontal tissues in Kidney deficiency models were severer than those of the models without Kidney deficiency. The results showed that the function of the traditional medicine was a matter of protection, regeneration and repairing to the periodontal tissues of Kidney Yin deficiency models. In addition, the weights and activities of the experimental animals fed by Decoction of Six Ingredients with Rehmannia were higher than those without taking the traditional medicine.
