Muscle fluorometry: A determination of the depth of penetration

Summary Fluorometric recordings of NADH (nicotinamide adenine dinucleotide) were made on rabbit papillary muscles. The specimens were placed between the UV light source and a small window of the detection stage. As the muscle was moved over the window in a transverse direction, simultaneous measurement could be taken of transmitted UV light and fluorescent light for various thicknesses of tissue. It is concluded that a muscle thinckness of 0.65 mm, is optimal before absorption of the incident light decreases the fluorescence signal.     

混合结构建筑温度收缩应力的近似计算

目前国内的混合结构建筑，由于温度变化以及材料伸缩等原因引起的墙体裂缝现象较为普遍。根据混合结构房屋构件之间的相互约束以及协同工作的关系，文章提出了温度收缩应力和变形的近似计算方法。计算结果表明，与现场实测的结果吻合较好，计算公式可供工程实践参考。     

Integrins and cardiovascular disease

Cardiovascular diseases involve abnormal cell-cell interactions leading to the development of atherosclerotic plaque, which when ruptured causes massive platelet activation and thrombus formation. Parts of a loose thrombus may detach to form an embolus, blocking circulation at a more distant point. The integrins are a family of adhesive cell receptors interacting with adhesive proteins or with counterreceptors on other cells. There is now solid evidence that the major integrin on platelets, the fibrinogen receptor α _IIb  β ₃ , has an important role in several aspects of cardiovascular diseases and that its regulated inhibition leads to a reduction in incidence and mortality due to these disorders. The development of α _IIb  β ₃ inhibitors is an important strategy of many pharmaceutical companies which foresee a large market for the treatment of acute conditions in surgery, the symptoms of chronic conditions and, it is hoped, maybe even the successful prophylaxis of these conditions. Although all the associated problems have not been solved, the undoubted improvements in patient care resulting from the first of these treatments in the clinic have stimulated further research on the role of integrins on other vascular cells in these processes and in the search for new inhibitors. Both the development of specific inhibitors and of mice with specific integrin subunit genes ablated have contributed to a better understanding of the function of integrins in development of the cardiovascular system.

Intercellular dye-coupling in intestinal smooth muscle. Are gap junctions required for intercellular coupling?

Summary The dye Lucifer Yellow was injected into single smooth muscle cells in the guinea pig small intestine in order to study intercellular coupling. Dye-coupling was observed in both the circular and longitudinal muscle layers and was markedly reduced when the intercellular pH was lowered. These results suggest the presence of gap junctions among intestinal muscle cells, but are inconsistent with previous ultrastructural studies that failed to demonstrate such junctions in the longitudinal muscle.

化橘红中主要活性成分对豚鼠气管平滑肌细胞增殖的影响

目的：初步观察化橘红中主要活性成分对豚鼠气管平滑肌细胞增殖的影响。方法通过原代培养豚鼠气管平滑肌细胞,采用 MTT 法观察化橘红中主要活性成分柚皮苷（Naringin）、橘皮内酯（Meranzin）和水合橘皮内酯（Meranzin hydrate）对细胞增殖的影响。结果柚皮苷（0.2~2.0 mg/mL）对豚鼠气管平滑肌细胞增殖有明显的促进作用（P<0.01）,水合橘皮内酯（0.1~1.0 mg/mL）对豚鼠气管平滑肌细胞增殖有明显的抑制作用（P<0.01）,橘皮内酯（0.05~0.5 mg/mL）对豚鼠气管平滑肌细胞的增殖作用不明显（P ＞0.05）。结论柚皮苷与水合橘皮内酯可能是化橘红主要药效活性成分。
