摘要
The amounts of somatostatin and sulfhydryl group were measured in malignant tumors of melanoma S91,Lewis lung cancer, sarcoma S180 and their surrounding tissues. All the tumors had decreased levels of somatostatin compared to their surrounding tissues whereas the amounts of sulfhydryl group in tumors increased evidently. The results suggest that the loss of somatostatin in tumor tissues may be induced by sulfhydryl group, which reduce the intramolecular disulfide bond of somatostatin.
