[Protective Effect of S-isopentenyl-L-cysteine against DNA Damage in Irradiated Mice].

Objective: To evaluate the protective effect of S-isopentenyl-L-cysteine,a new cysteine derivative,on DNA damage induced by radiation by using acute radiation injury animal models.

Methods: Forty ICR mice were randomly divided into five groups:the control group,1.0Gy gamma irradiation group,1.

Study on incompatibility of traditional chinese medicine: evidence from formula network, chemical space, and metabolism room.

A traditional Chinese medicine (TCM) formula network including 362 TCM formulas was built by using complex network methodologies. The properties of this network were analyzed including network diameter, average distance, clustering coefficient, and average degree. Meanwhile, we built a TCM chemical space and a TCM metabolism room under the theory of chemical space.
