高压氧中毒小鼠脑微血管图像分析定量研究

本文采用计算机图像定量测量方法，对高压氧中毒后小鼠软脑膜微血管和大脑皮质毛细胞血管内皮细胞碱性磷酶活性进行了定量检测。结果表明，ＨＢＯＩ后小鼠软脑膜毛细血管开放数目减少，毛细血管密度降低。     

积分加权法评价磷化学烧伤实验病理的意义与应用

目的：积分加权法在病理组织学检查中的应用，方法：在常规病理描述基础上，采用积分加权法将病理结果予以定量，综合评价致伤后实验动物的主要脏器，结果：实验动物同等面积的磷酸烧伤各脏器积分降低，钙治疗后则显著改善，均与其它方面报道的资料一致，结论：积分加以数值使各脏器损伤程度一目了然，对不同脏器间的损伤情况有可比性，从而有助于了解主要受损脏器与总体的关系以及药物的治疗效果。     

海水淹溺肺水肿兔血浆MDA和SOD的变化

目的 :观察海水淹溺肺水肿 (PE SWD)兔血浆中丙二醛 (MDA)和超氧化物歧化酶 (SOD)变化规律 ,探讨上述两项指标发生变化的原因和机制。方法 :用核黄素光照法和硫代巴比妥酸法 ,对PE SWD兔动脉血浆MDA和SOD进行定量检测和动态观察。结果 :灌海水后 30min ,MDA和SOD较灌海水前均显著升高 ,尔后两者均逐渐下降 ,但仍远远高于灌海水前。结论 :PE SWD发生发展过程中 ,MDA的损害性作用使肺泡表面活性物质表面特性发生改变 ,影响了正常的呼吸功能 ,并掩盖了SOD的保护性作用。     

色素绒毛结节性滑膜炎28例报道

目的探讨色素绒毛结节性滑膜炎(PVS)的临床病理特点、治疗和预后的关系。方法本组PVS28例,男13例,女15例,年龄12～53岁。膝关节15例,手指7例,足背4例,颞颌及骶髂关节各1例,多肢体1例。局限型19例,弥漫型9例。伴外伤史3例,骨破坏4例,恶变2例,半月板破裂1例,滑膜血管瘤1例。均行滑膜切除,早期操练,3例加放疗。28例均经病理证实。结果22例随访2～18年,13例功能良好;9例复发5例功能欠佳,2例截指(趾),2例死亡。放疗3例均复发。结论PVS临床病理均有肿瘤的特征,可恶变和转移,易复发,最佳治疗是彻底的滑膜切除而不是放疗。     

Experimental observation of living cells on the surface of intraocular lenses

目的 :对比观察后房型人工晶状体植入术后晶状体表面细胞染色前后的数量、形态。方法 :2 0只兔行后房型人工晶状体植入术。分别于术后 1 ,3,7,1 4和 2 8d分组取出人工晶状体放入1 640细胞培养液于倒置显微镜下观察。结果 :术后 1～ 2 8d人工晶状体表面有细胞粘附 ,染色后细胞形态失去立体外观 ,体积小 ,细胞数量较染色前明显减少。结论 :人工晶状体表面细胞在染色过程中有部分脱落。脱落的细胞数量可以计数比较 ,但细胞类型无法确定。因此需寻找更精确可靠的仪器及方法 ,以免造成实验误差。     

Changes of type I collagen in the lungs of rats with hypoxic pulmonary hypertension]

The changes of type I collagen in the lung tissues of rats with hypoxic pulmonary hypertension (HPH) and its relationship to the mean pulmonary arterial pressure (mPAP) were investigated. The blood dynamic indexes of pulmonary circulation were measured by using Swan-Ganz. The distribution of type I collagen in pulmonary arteries, bronchi and plumonary interstitial was observed by using streptavidin peroxidase method (SP). The morphologic changes of small pulmonary arteries and the level of type I collagen were determined by image pattern analysis technique and gray scale scanning, respectively. The results showed, compared with the controls, mPAP of the hypoxic rats elevated (from 2.12 +/- 0.25 to 3.95 +/- 0.43 kPa, P < 0.01), their small pulmonary arteries, walls thickened (MT% from 16.35 +/- 2.64 to 35.83 +/- 3.55, MA% from 26.83 +/- 3.40 to 59.68 +/- 4.90, P < 0.01) and lumen narrowed. The distribution of type I collagen was mainly in the external layer of pulmonary arterial walls; the positive degrees of gray scale scanning increased and had a positive linear relationship to the mPAP and MT%. These findings suggest that the increase of type I collagen contents in pulmonary arteries is closely related to the development of HPH.     

KATP通道开放剂KRN2391对离体大鼠心肌梗死范围的影响
