Examination of enzymic activities and histochemical reactions on needle pricks can be used to determine the age of micro-injuries with sufficient exactness. Well preserved skin shows patterns of enzymes which also appear with other skin injuries and which were described in detail especially by Raekallio (1970, 1972). In autolytical changes of the skin the adenosinetriphosphatase-reaction is still reliable and can be successfully estimated. If one has sufficient experience it is possible to fairly exactly estimate the age of an injury within the first hour after the injury by preparation of the adenosinetriphosphatase-reaction. If the times of injections are known one frequently succeeds in determining the time of death by exactly determining the age of the injury. In legal expertises the histochemical reactions can rightly be regarded as useful indications of a certain age of the injury. But they do not allow an exact estimate "beyond a reasonable doubt".
对针刺处进行酶活性和组织化学反应检查，可用于足够精确地确定微损伤的时间。保存良好的皮肤会显示出酶的模式，这些模式也会出现在其他皮肤损伤中，尤其是雷克利奥（1970年、1972年）对此进行了详细描述。在皮肤的自溶变化中，三磷酸腺苷酶反应仍然可靠，并且可以成功评估。如果有足够的经验，通过制备三磷酸腺苷酶反应，有可能在损伤后的第一小时内相当准确地估计损伤的时间。如果注射时间已知，通过准确确定损伤的时间，常常能够成功地确定死亡时间。在法医鉴定中，组织化学反应可以恰当地被视为损伤特定时间的有用指标。但它们无法“排除合理怀疑”地进行精确估计。
