Abstract： 目的研究α-干扰素(IFN-α)和溴隐亭(BC)对人垂体腺瘤细胞激素分泌的影响.方法将垂体生长激素(GH)腺瘤(11例)进行体外细胞培养,每例培养细胞随机分成IFN-α组、BC组、IFN-α+BC组及对照组,每组3管,观测药物干预后细胞激素分泌量.结果干预2d和4d时,IFN-α对6/10例和7/10例垂体腺瘤细胞GH分泌有明显抑制,与对照组比较GH分泌量减少22%～54%(P＜0.05或P＜0.01)和30%～61%(P＜0.01),其中,4/6例和5/6例侵袭性垂体腺瘤细胞GH分泌受到明显抑制,与对照组比较GH分泌量减少22%～38%(P＜0.05或P＜0.01)和30%～55%(P＜0.01);BC对5/10例垂体腺瘤细胞GH分泌无明显抑制作用,而IFN-α对其中4例有明显抑制GH分泌效应,与对照组比较GH分泌量减少22%～54%(P＜O.05或P＜0.01)和30%～61%(P＜0.01).结论IFN-α对大多数垂体GH腺瘤,尤其是侵袭性垂体腺瘤细胞GH分泌有抑制作用,对大多数BC耐药的垂体腺瘤细胞GH分泌亦有抑制效应.
