beta-Endorphin-like immunoreactivity (beta-ELI) was measured in hypophysial portal and arterial blood of intact, adrenalectomized and hypophysectomized rats. beta-ELI levels were 61 times higher in the long portal vessels than in the general circulation. Circulating, and especially portal, levels of beta-ELI were significantly increased after adrenalectomy. After removal of the pituitary gland, the mean level of beta-ELI in portal blood was significantly lower than in intact rats. beta-ELI in portal blood displayed the same chromatographic properties as synthetic beta-endorphin.
在完整、肾上腺切除和垂体切除大鼠的垂体门脉血和动脉血中检测了β-内啡肽样免疫反应性（β-ELI）。长门静脉血管中的β-ELI水平比体循环中的高61倍。肾上腺切除术后，β-ELI的循环水平，尤其是门脉水平显著升高。切除垂体后，门脉血中β-ELI的平均水平显著低于完整大鼠。门脉血中的β-ELI具有与合成β-内啡肽相同的色谱特性。
