Inhibitory effect of Patrinia scabiosaefolia on acute pancreatitis

瞄准：在缩胆囊素(CCK ) 上调查 Patrinia scabiosaefolia (PS ) 的效果在老鼠的导致 octapeptide 的尖锐胰腺炎(AP ) 。方法：称 240-260 g 的 Wistar 老鼠被划分成三个组：(1 ) 正常的盐对待的组；(2 ) 在哪个 PS 口头上地被管理，有在 100 mg/kg 组的 PS 的处理在 1， 3 和 5 h，和这个全部以后由 75 microg/kg CCK octapeptide 的下的管理列在后面三次过程为 5 d 被重复；(3 ) 与盐的组，协议与在处理一样在是一起的处理与 PS 组织。我们决定了胰腺的重量 / 身体重量比率，胰腺的 HSP60 的层次， HSP72 和支持 inflammatory cytokines 的分泌物。重复 CCK octapeptide 处理导致了试验性地导致的胰腺炎的典型实验室调查结果。结果：PS 在 CCK 导致 octapeptide 的 AP 减少了胰腺的重量 / 身体重量比率，浆液淀粉酶和脂肪分解酵素的层次，和支持 inflammatory cytokines 的禁止的表情。而且， PS 预告的处理增加了 HSP60 和 HSP72 的胰腺的层次。结论：有 PS 的预告的处理在 CCK 导致 octapeptide 的 AP 上有反煽动性的效果。

Dendrite Spacing Selection during Directional Solidification of Pivalic Acid-Ethanol System

Unidirectional solidification of pivalic acid （PVA）-ethanol （Eth） mixture was performed to examine whether an allowable range of primary dendrite spacing definitely exists at a given growth velocity and how the range is history-dependent. PVA-0.59 wt pct Eth was unidirectionally solidified in the range of growth velocity 0.5-64 μm/s at the temperature gradient of 2.3 K/ram. Sequential change in growth velocity was imposed to determine the upper and lower limits for the allowable range of stable spacing. An allowable range of the steady state primary spacing was observed at a given growth velocity, and the extent of the range seems to be dependent on the degree to which step-increase or step-decrease in growth velocity is accomplished. As the degree of sequential change in growth velocity increases, the history-dependence of the selection for the primary dendrite spacing tends to disappear.
