Abstract

AIM: To study the immunoreactivity of the Chinese medicine Shenrouyangzhentang to vasoactive intestinal polypeptide (VIP) and its therapeutic mechanism.

METHODS: The immunoreactivity of the Chinese medicine Shenrouyangzhentang to VIP was detected in the plasma of 20 normal people and 20 patients with Piyinxu (Spleen Yin deficiency) using the radioimmunoassay (RIA) method.

RESULTS: The maximum binding rate B0/T was 53.29%, the non-specific binding rate N0/T was 1.170%, and the VIP standard curve was Y = 0.81983 + 0.44319X - 0.28927X2, R2 = 0.990. The VIP content in Shenrouyangzhentang was 106.6 ng/L ± 20 ng/L), while it was 90.16 ng/L ± 15 ng/L in normal human plasma and 63.25 ng/L ± 11 ng/L in the plasma of Pixinxu patients. The difference between normal plasma and Pixinxu patient plasma was statistically significant (P < 0.05).

CONCLUSION: The Chinese medicine Shenrouyangzhentang demonstrated VIP immunoreactivity similar to that of normal plasma. The (vasoactive intestinal polypeptide) VIP content in Pixinxu patient plasma was lower than that in healthy subjects (P < 0.05).
