皮质性白内障

Objective To explore the relationship between lens epithelial cells apoptosis and conical cataract formation.

目的探讨晶状体上皮细胞凋亡与皮质性白内障形成的关系。

In our experiments, when the opacity of lens exceed Ⅳ degrees, the treatment effect of medicine was not obviously. Analyzing the examined results of AR, SOD and GSH-px in rat lens cortex and nuclear shows that Zhangming drops can inhibit the activity of AR obviously and prevent the translation of galactose to galactose alcohol. So it can prevent the deposit of galactose in the fibrocyte of lens and the increase of lens's osmosis, then prevent the hydration of lens.

通过对大鼠半乳糖性白内障晶体皮质和核内醛糖还原酶、超氧化物歧化酶和谷胱苷肽过氧化物酶的检测结果分析表明，障明滴眼液能明显抑制AR的活性，防止半乳糖向半乳糖醇的转化，从而防止半乳糖在晶体纤维细胞内的堆积，阻止其渗透性的增高，防止晶体的水化。

The most common types of cataract were cortical and posterior subcapsular opacities.

最常见的白内障种类是皮质性和后囊的水晶体混浊。

Methods Immunohistochemistry was used to detect the expression of OPN and CD44 in the LECs of anterior subcapsular cataracts(22 cases)、nuclear cataracts(17 cases)、cortical cataracts(14 cases) and normal lenses(11 cases),and positive cells were counted.

方法采用免疫组织化学法检测22例前囊下白内障1、7例核性白内障、14例皮质性白内障患者和11例正常晶状体上皮细胞中OPN和CD44的表达，并进行阳性细胞计数和各组间比较。

Oncosis cells were found in all samples, three nuclear cataract and four cortical cataract had paraptosis cells, but only one sample had apoptosis cell.

所有标本均发现胀亡细胞，3例核性白内障及4例皮质性白内障标本发现典型paraptosis样细胞，仅有1例核性白内障标本发现早期凋亡细胞，细胞内偶见髓样体存在。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
