为了观察碱性成纤维细胞生长因子（ｂＦＧＦ）对大鼠缺血皮瓣坏死率、琥珀酸脱氢酶（ＳＤＨ）含量和氧耗量的影响，选用Ｗｉｓｔａｒ大鼠１８只，随机分为对照组和实验组。制成背部皮瓣，原位缝合，皮瓣下滴注０．２５ｍｌ肝素化生理盐水或ｂＦＧＦ９μｇ。术后７天，计算皮瓣坏死率。再将皮瓣从蒂部开始平均分成近、中、远三段，以定量组织化学方法和生物组织氧耗仪测定ＳＤＨ含量和氧耗量。结果表明，实验组皮瓣坏死率为１８．２１％，对照组为３７．１４％（Ｐ＜０．０５）；实验组中段和远段皮瓣ＳＤＨ含量高于对照组相应部位（Ｐ＜０．０５）；仅有远段皮瓣氧耗量高于对照组相应部位（Ｐ＜０．０５）。提示，ｂＦＧＦ可降低缺血皮瓣坏死率，使皮瓣维持较高的ＳＤＨ含量和氧耗量。其机制可能与ｂＦＧＦ能诱导受创部位毛细血管再生，增加组织血供，减轻皮瓣损伤有关。深入研究ｂＦＧＦ，可能有一定的临床应用价值。
In order to observe the effect of basic fibroblast growth factor (bFGF) on the necrosis rate, succinate dehydrogenase (SDH) and oxygen consumption of ischemic skin flap in rats, 18 Wistar rats were randomly divided into control group And experimental group. Made of the back flap, suturing in situ, 0.25ml heparinized normal saline or bFGF 9μg. Seven days after operation, the flap necrosis rate was calculated. And then the flaps from the pedicle began equally divided into near, middle and far sections, quantitative tissue chemistry and biological tissue oxygen analyzer determination of SDH content and oxygen consumption. The results showed that the skin flap necrosis rate was 18.21% in the experimental group and 37.14% in the control group (P <0.05). The content of SDH in the experimental group was higher than that in the control group .05). Only the distal flap oxygen consumption was higher than that of the control group (P <0.05). Tip, bFGF can reduce the necrosis of the flap rate of necrosis, the flap to maintain high SDH content and oxygen consumption. The mechanism may be associated with bFGF induced capillary wound regeneration, increased blood supply to the organization to reduce the skin flap injury. In-depth study of bFGF may have some clinical value.
