报告了用气相色谱法测定血浆支链酮酸（Ｂｒａｎｃｈｅｄ－ＣｈａｉｎＫｅｔｏＡｃｉｄｓ；ＢＣＫＡ’ｓ）浓度，以及静脉输注高浓度Ｌ－缬氨酸（Ｌ－ｖａｌｉｎｅ，ｖａｌ）治疗半乳糖胺引起兔肝昏迷（ＨｅｐａｔｉｃＣｏｍａ； ＨＣ）的结果。ＨＣ兔血浆ＢＣＫＡ’Ｓ明显低于正常组水平，相对应的支链氨基酸（Ｂｒａｎｃｈｅｄ－Ｇｈａｉｎ Ａｍｉｎｏ ａｃｉｄｓ；ＢＣＡＡ’Ｓ）及其它氨基酸多数增高，芳香族氨基酸（ＡｒｏｍａｔｉｃＡｍｉｎｏＡｃｉｄｓ；ＡＡＡ＇Ｓ）大幅度升高，用５％ｖａｌ静脉输注４８ｈ，血浆ＢＣＫＡ’Ｓ提高约３倍，ＢＣＡＡ’Ｓ改变不大，ＡＡＡ’Ｓ下降３７％；血浆ＢＣＫＡ’Ｓ／ＢＣＡＡ’Ｓ、ＢＣＡＡ’Ｓ／ＡＡＡ’Ｓ比值也明显增高。提示，高浓度ｖａｌ能纠正ＨＣ血浆ＢＣＫＡ’Ｓ及主要氨基酸紊乱。
Reported the determination of plasma concentrations of Branched-Chain Keto Acids (BCKA’s) by gas chromatography and the treatment of galactosamine-induced hepatic hepatic coma by high-dose intravenous infusion of L-valine (val) HepaticComa; HC) results. The BCKA’s in plasma of HC rabbits were significantly lower than that of the normal group, the majority of branched-chain amino acids (BCAA’s) and other amino acids were increased, and the Aromatic Amino Acids (AAA’s) were greatly increased , With 5% val intravenous infusion 48h, plasma BCKA’s increased about 3 times, BCAA’S little changed, AAA’S decreased 37%; plasma BCKA’S / BCAA’S, BCAA’S / AAA’S ratio Also significantly higher. Tip, high concentrations of val can correct HC plasma BCKA’S and major amino acid disorders.
