摘要 为了探索胎兔及成兔在正常发育及创伤愈合过程中的胶原合成特点,分析胎儿型及成年型愈合区别的潜在原因,用胃蛋白酶对胎兔及成兔皮肤的胶原进行提取,用酸水解法使胶原水解成羟脯氨酸(HP),采用氯胺T法进行测定。结果表明:①正常成兔的HP含量明显高于正常胎兔(P〈0.001),而正常胎兔不同孕期之间却无差别。②胎兔皮肤创伤后(1~6天)与对应的正常胎兔相比,只表现出第1天HP显著增高(P〈0.05)。③成兔皮肤创伤后与正常成兔相比,除第1天无差别外,后5天HP显著增高(P〈0.05)。④胎兔皮肤创伤后HP动态变化呈现线性下降趋势,而成兔呈现线性上升趋势。上述结果提示,成兔皮肤合成胶原的能力高于胎兔皮肤:创伤后,胎兔及成兔均表现出胶原合成增加,而前者极为短暂,预示着愈合迅速;而后者持续增高,表现出愈合缓慢及瘢痕的形成。
