在单纯培养神经细胞中0.5mmol／LL－NNA对H／R＋SIN－1导致的LDH漏出率增加仍无显著抑制作用，但可显著抑制H／R引起的混合培养的神经细胞和神经胶质细胞的LDH漏出率。

To evaluate the light injury to retina, DNA changes in rabbit retina were quantitativaly studied after exposure to indirect ophthalmoscopic light.

为评价光照性视网膜损伤，本文研究了间接检眼镜光照后试验兔视网膜DNA定量的变化。

Methods Outbred stock ICR and inbred B6 female mice (3 weeks of age) were fed HFD, HFD-fructose and standard rodent chow, respectively. After exposure to the diets for 6 weeks, HFD and HFDF groups were injected intraperitoneally with STZ, and controls were injected with vehicle,then kept on the same diet for the next 6 weeks.

分别以高脂饲料、高脂饲料－果糖饮水和常规饲料喂养3周龄的封闭群ICR和近交系C57BL/6J(B6)小鼠6周后，HFD和HFDF组腹腔注射STZ，对照组注射相应体积柠檬酸钠溶液，然后分别以相应饲料继续喂养6周。

Results:(1) The pial microarteries contracted after exposure to HBO.

Results Pycnosis and deep staining of neurons, deposits of synapse vesicles and bluring of synapses, fusion and dissociatio of myelin sheaths which were exposed to 10, 50 and 90 mW/cm^2 HPM were observed. The contents of the above four amino acids elevated more markedly on 6 h than those of controls, but on 1 d only the elevation of GABA and glycine after exposure to 10 and 50 mW/cm^2 HPM was observed.

结果平均功率密度10，50和90mW/平方公分S波段高功率微波可引起大脑皮层神经元固缩、深染，尼氏体减少；突触结构模糊，囊泡堆积；髓鞘融合、解离等。10和50mW/平方公分组照后6h大脑皮层上述4种氨基酸含量均显著增高(P.01)；而照后ld仅见γ-氨基丁酸和甘氨酸含量仍较高(P.01)。

In 1-7d group, the difference between experimental group and control group was not significant. In 14-21d group, Bcl-2mRNA and P53mRNA were expressed lightly. In 28d group, the expression were comparatively strong. The results indicated that, after exposure to infrasound with some parameters, with the days elapsing, Bcl-2mRNA expression in neurons of mice hippocampus displayed certain regularity. The progressive increase suggested that infrasound could injure hippocampus, and resultantly, injure and repair neurons DNA.

据此，我们认为：当一定参数的次声作用小鼠后，随着作用天数的延长，小鼠海马内神经细胞Bcl-2mRNA表达有一定规律性，总体趋势表达增强，随次声作用次数进一步增多，21d组和28d组有产生适应的倾向，其意义在于次声作用后引起海马损伤，使神经元DNA损伤并产生修复。
