ABSTRACT

Objective:

To observe the effect of Shenghuitang on learning and memory and expressions of interleukin-6(IL-6), tumor necrosis factor-α(TNF-α) and cyclooxygenase-2(COX-2) in hippocampus of chronic sleep deprived mice, in order to explore the possible mechanism of Shenghuitang in improving learning and memory ability.

Method:

Mice were randomly divided into sleep deprivation group, blank group, melatonin group(7.8×10-4 g·kg-1·d-1), high, middle and low-dose Shenghuitang groups(54,27,13.5 g·kg-1·d-1). The model of chronic sleep deprivation in mice was established using the "multi-platform water environment method". 28 d sleep deprivation and intragastric administration were provided. Morris water maze was used to detect the learning and memory ability of mice in each group. Real time-PCR was used to detect mRNA expressions of IL-6, TNF-α and COX-2 in the hippocampus of each group.

Result:

The results of Morris water maze test showed that compared with the blank group, the total time spent on finding the platform and the total swimming distance of the model group were significantly prolonged (PPPPPPPPPα, and COX-2 were increased in the model group compared with the blank group. Compared with the model group, mRNA expressions of IL-6, TNF-α, and COX-2 were decreased in the treated group. COX-2 mRNA expression was down-regulated.

Conclusion:

Shenghuitang may improve the learning and memory ability of mice by decreasing mRNA expressions of IL-6, TNF-α and COX-2 in hippocampus.
