附錄五 肌肉穿刺步驟

1、在人體右側大腿找到股外側肌肉(vastus lateralis),並做記號。

2、於記號處使用優碘與酒精各消毒三次。

3、鋪蓋已殺菌之洞巾。

4、注射 1-2 毫升局部麻醉藥 (2% Lignocaine),內含血管收縮素防止出血。

5、使用 14 號肌肉穿刺針取得股外側肌肉樣本,取樣過程非常迅速,用一次即丟 棄。

6、取出穿刺針後,局部再用優碘消毒,並用紗布壓迫止血,受試者休息 30 分鐘 防止出血。若還有疼痛,再加以冰敷。

7、為防感染,受試者 2 天內禁止傷口碰水,並且每天更換紗布。

8、為防傷口再出血,三天內禁止運動,一星期內禁止激烈運動。

56

5、室溫下加入 250μl 的 0.3M sodium acetate buffer,pH=4.8,vortex 均勻。

6、立即調配冰醋酸水溶液 (glacial acetic acid : ddH2O = 1 : 1) 置於小管中,小管 需用錫箔紙包起避光;加入 10μl 冰醋酸水溶液於肌肉樣本溶液中,vortex。

7、加入 250μl Amyloglucosidase (Amyloglucosidase in 0.3M sodium acetate buffer, 10mg/ml, pH=4.8),vortex。

8、室溫下靜置至少 12 小時。此時可先 label 好隔天要用的小管 (2 ml)。

57

11、肌肉樣本溶液取 150μl 各裝成 2 小管。

12、加入 1.5ml 呈色劑 (glucose color reagent,Trinder),注意時間間隔,約每 30 秒加一管,才可控制每管的反應時間相同,vortex 均勻。

13、室溫下靜置 21 分鐘,第 21 分鐘使用分光光度計 Beckman DU 650

UV-Spectrophotometer(Beckman Coulter, Inc., Fullerton, CA) 檢測,波長定為 505nm。

14、輸出資料,進行資料分析。
