OBJECTIVETo evaluate the effect of compound bushen recipe (CBR) in improving the survival state of stress and the overall life span in C. elegans by simulating chronic fatigue syndrome (CFS) under various stress states.
METHODSThe tolerance and the average survival time of adult larvae against heat stress (35 degrees C), oxidative stress (250 microg/mL juglone), and in vivo Abeta protein toxicity (Abeta(1-42) transgenic mutant CL4176) under the intervention of the high (500 mg/L), middle (250 mg/L), and low (100 mg/L) dose CBR were observed. The effect of CBR on the average live time (at 25 degrees C), movement distance in 20 seconds, the frequency of pharyngeal pump in 30 seconds, and the reproductive capability were assessed.
RESULTSCompared with the control group, the survival time of heat stressed C. elegans could be significantly increased in each CBR group (P < 0.01). The survival time of heat stressed C. elegans could be elongated, the protein toxicity be attenuated, and the live time prolonged in the high and middle dose CBR groups (P < 0.01, P < 0.05).The movement distance and the frequency of pharyngeal pump could also be increased in the high dose CBR group (P < 0.01). There was no statistical difference in the reproductive capability among all groups (P > 0.05).
CONCLUSIONSCBR could significantly enhance the stress capacity of C. elegans against internal and external environment, and prolong their lifespan. It did not interfere their normal production, and also could improve the quality of life, thus laying a foundation for further mechanism studies and pharmacological researches on CBR in preventing and treating CFS.
