Radio-protective effects of Thymus quinquecostatus Celak extract in mice

초록

Thymus quinquecostatus Celak (TQC) is an aromatic herb, that possesses a wide range of biological properties. In the present study, we investigated the radio-protective effect of TQC water extract (TQCW) in gamma ray -exposed splenocytes, a peripheral immune cell and mice. Our results showed that the treatment with TQCW dose-dependently increased the viability of splenocytes. TQCW significantly increased the proliferation of splenocytes by reducing the production of intracellular reactive oxygen species (ROS) in 2 Gy-exposed spleno-cytes. Moreover, TQCW enhanced the hemopoietic system as increasing the number of endogenous spleen colony-forming units, and the number and the proliferation of splenocytes in 7 Gy-exposed mice. These results suggest that TQCW protects mice by enhancing the splenocytes proliferation and hemopoietic systems following exposure to gamma rays.
