中文摘要

研究目的：

研究明日葉對過度訓練致大鼠胃腸功能紊亂的作用。

研究方法：

建立雄性大鼠過度訓練模型，觀察過度訓練組、補充明日葉組的大鼠腸道主要菌群雙歧桿菌、大腸桿菌數量，腸道代謝產物脲酶、β-半乳糖苷酶活性和主要 SCFA 含量，以及血漿內毒素、組織勻漿 SIgA 含量的變化。

實驗結果：

與正常對照組比較，過度訓練組雙歧桿菌數量及 B/E 比值顯著升高，大腸桿菌數量顯著降低；β-半乳糖苷酶活性及主要 SCFA 乙酸、丁酸含量顯著降低，脲酶活性顯著升高；組織勻漿 SIgA 含量顯著下降，而血漿內毒素含量顯著升高。補充明日葉組各指標與對照組比較均無顯著差異。

研究結論：

結果表明，明日葉能夠從腸道菌群、腸道代謝產物及腸道屏障等幾個方面對腸道微生態進行綜合調理，促進腸道健康。

關鍵詞：明日葉；過度訓練；運動型胃腸綜合症；腸道微生態

Abstract：

The effect of Ashitaba on gastrointestinal disorders induced by overtraining rat was studied. Male overtraining rats were used as research rats.

For exercise，overtraining and Ashitaba supplement，the changes in the numbers of Bifidobacterium and E.coli，the activity of β-galactosidase and urease，the content of SCFA，SIgA and plasma endotoxin were measured.

Compared with normal control group，in overtraining group，the number of Bifidobacterium and the ratio of B/E were significant increased，the number of E.coli was decreased. The activity of β-galactosidase and the levels of acetic acid and butyric acid were remarkably lower in over－training group，in contrast，the activity of urease was higher. The content of SIgA of overtraining groupwas no－tably falling，on the contrary，the level of plasma endotoxin was rising.

For the study，ashitaba has a good abili－ty to improve ntestinal microecology，such as intestinal flora，intestinal metabolites and intestinal barrier，to promote gut health with a comprehensive and integrated effect.

Key words：Ashitaba；overtraining；sports gastrointestinal syndrome；intestinal microecology
