ABSTRACT
Objective To observe the effects of wild jujube seed decoction(WJSD) on ultrastructure and astrocytes expression in the brain cortex of old model rats with blood-deficiency and Yin and sleep deprivation(SD)after SD. Methods Ultrastructural changes in cortical parts of the experiment rat were observed by transmission electron microscopy , immunohistochemical staining was used to detect star-shaped glial cells marker-glial fibrillary acidic protein(GFAP) expression after SD induced by made-self multiple platform method (MMPM), senescence induced by D-galactose, and Yin and blood-deficiency induced by cyclophosphamide and hydrocortisonum. Results Compared to environmental control group((9.8 ± 2.5), (0.11 ± 0.02) ) , syndrome model group (( 20.4 ±4.4), (0.20 ±0.011) ) rats had obvious ultrastructural changes and stronger expression of GFAP in cortical parts (t = 7.63,3.18, P < 0. 01), while those of W J SD of high and low dose group ((14.4 ± 3.9), (15.5 ± 6.4),(0.14 ±0.02)(0.14±0.02)) rats showed weaker(t=6.32,5.24,2.31,2.45, P<0.05). Conclusion WJSD of large and small lose group could improve the rats neurons pathological changes,WJSD downward adjusting the expression of GFAP may be one of the mechanisms of treatment on insomnia with blood-deficiency and Yin in the old.
