Unsaturation of fatty acids in thylakoid membrane was accelerated, which might be helpful to stabilize photosynthetic apparatus. Distortion and swelling of grana caused by chilling in the dark probably decreased activities of antioxidant enzymes, which resulted in the accumulation of active oxygen species.

低温弱光胁迫对膜脂脂肪酸组成和叶绿体超微结构的影响均比暗中低温胁迫严重，而活性氧清除酶的活性有所下降，活性氧积累。

Results: in contrast with model group, SSM can (1) increase the survival rate of ARF in rats, cut down Scr and BUN at 24hr, improve renal function, slightly surpass Vp in its therapeutic effect;(2) mitigate the extent of renal pathologicchanges, decrease the numbers of renal tubule necroses and casts;(3) protect renal ultrastructure such as microvilli, mitochondria, endoplasmic reticulum of TEC, podocytic process of glomerulus epithelial cell,endothelial cell etc, better than Vp;(4) enhance SOD activity, lower MDA contents in renal cortex;(5) enhance NO contents in serum, reduce ET levels in plasma;(6) evidently cut down TNF- a contents in serum, superior to Vp;(7) antagonize calcium overload in TEC;(8) alleviate renal pathological changes in ARF metaphase (at 3d), advance regeneration and recovery of TEC, restore renal structure in ARF convalescence (at 5d), and better than Vp;(9) increase the expression of TEC PCNA and prepro EGFmRNA in ARF metaphase.
