项目摘要
Heparin and Protamine Sulfate are charged substances which are widely used
clinically. Recently it has been appreciated that protamine may cause
serious adverse reactions when it is given to reserve the anticoagulant
effects of heparin. In the first part of this project, we will examine the
mechanism by which protamene may exert these reactions. We will study
whether they are due to Type I hypersensitivity and/or whether the effect
may be mediated through complement. We will examine the prevalence of
positive immediate or delayed skin tests and IgG and IgE anti-protamine in
patients who have received protamine containing insulin; in diabetics who
have not received protamine containing insulin; in men who have had
vasectomy; in other patients who have received protamine; in patients with
Type I hypersensitivity to fish; and in a normal population. We will
determine the true incidence and the mechanism(s) of hypersensitivity to
protamine when the drug is given, to reverse the anticoagulant effect of
heparin, to patients who will undergo cardiac catheterization and to
patients who will undergo open heart surgery. In the second part of the
project, we will examine heparin more fully to determine the Structure
Activity Relationship between its fragments and complements. We will study
the following polysaccharide mixtures to see which fragments are active in
regulating complement: tetrasaccharides, hexasaccharide, octasaccharide,
decasaccharide and larger polysaccharides. We will search for heparin
fragments of very low MW which have the minimum structure necessary to
regulate complement as actively as does commercial heparin. We will
examine other heparin-like molecules to determine if they are able to exert
the same effects on complement. We will examine other polycations to
determine whether they have the same effect. Finally, we will determine if
Major Basic Protein, an important constitutent of the eosinophil, may
similarly modulate the complement system.
肝素和硫酸鱼精蛋白是广泛使用的带电物质
从临床上看。最近,人们意识到鱼精蛋白可能会导致
使用预留抗凝剂时出现严重不良反应
肝素的作用。在本项目的第一部分中,我们将研究
鱼精蛋白可以进行这些反应的机制。我们会研究
无论它们是由于I型超敏反应和/或
可能通过补体来调节。我们将检查流行性出血热
即刻或延迟皮肤试验和抗鱼精蛋白免疫球蛋白和IgE抗体阳性
接受了含有胰岛素的鱼精蛋白的患者;糖尿病患者
没有接受过含有胰岛素的鱼精蛋白;
输精管结扎术;其他接受过鱼精蛋白的患者;
I型对鱼过敏;在正常人群中。我们会
确定超敏反应的真实发生率和机制(S)
给药时给予鱼精蛋白,以逆转其抗凝作用
肝素,给将接受心导管插入术的患者和
将接受心脏直视手术的患者。在第二部分中,
项目,我们将更全面地检查肝素以确定其结构
其片段与补体之间的活性关系。我们会研究
下面的多糖混合物,看看哪些片段是有效的
调节补体:四糖、六糖、八糖、
脱糖和较大的多糖。我们将寻找肝素
具有所需的最小结构的极低分子量碎片
像商业肝素一样积极地调节补体。我们会
检查其他类肝素分子以确定它们是否能够发挥作用
对补体也有同样的影响。我们将研究其他聚阳离子以
确定它们是否具有相同的效果。最后,我们将确定是否
主要碱性蛋白,嗜酸性粒细胞的重要组成部分,可能
类似地,调整补体系统。
