在幽门结扎的清醒大鼠中研究重组人白细胞介素-1β和-1α以及大鼠白细胞介素-1β对胃酸分泌的影响。 IC 注射人白细胞介素 1β、人白细胞介素 1α 或大鼠白细胞介素 1β 会诱导剂量依赖性胃酸排出抑制。当 IC 剂量 < 100 ng 时,人白细胞介素-1β 比其他形式或来源的白细胞介素-1 更有效,而在较高剂量(100-500 ng)时,人白细胞介素-1β 和 -1α 以及大鼠白细胞介素-1β 是等效的。在注射IL-1后30分钟观察到抑制作用,并在整个6小时的实验期间维持这种作用。 IC 注射白细胞介素 1β 可抑制由 IC 注射稳定促甲状腺激素释放激素类似物 RX 77368 诱导的迷走神经刺激胃酸分泌。吲哚美辛(1、5 和 10 mg/kg,IP,- 30 分钟)可诱导剂量相关的 IC IL-1β 抑制作用预防。 IC注射促肾上腺皮质激素释放因子拮抗剂α-CRF9-41、双侧肾上腺切除术和溴烯胺去甲肾上腺素能阻断并不影响IL-1的抗分泌作用。多肽作用与循环胃泌素水平的变化无关。静脉注射人白细胞介素-1β也能抑制胃酸分泌,但产生显着效果所需的外周剂量比中枢给药时高103倍。这些结果表明,IC IL-1β 的作用集中于诱导胃酸分泌的长期抑制,而这种作用需要前列腺素通路的完整性。这些数据表明免疫系统和胃肠系统之间可能存在相互作用。
The influence of recombinant human interleukins-1β and -1α and rat interleukin-1β on gastric acid secretion was investigated in awake rats with pylorus ligation. IC injection of either human interleukin-1β, human interleukin-1α, or rat interleukin-1β induced a dose-dependent inhibition of gastric acid output. At IC doses < 100 ng, human interleukin-1β was more effective than the other forms or sources of interleukin-1, whereas at higher doses (100–500 ng), human interleukins-1β and -1α and rat interleukin-1β were equipotent. The inhibitory effect was observed 30 minutes after interleukin-1 injection and maintained throughout the 6-hour experimental period. IC injection of interleukin-1β inhibited vagally stimulated gastric acid secretion induced by IC injection of the stable thyrotropin-releasing hormone analogue RX 77368. Indomethacin (1, 5, and 10 mg/ kg, IP, − 30 minutes) induced a dose-related prevention of the inhibitory effect of IC interleukin-1β. IC injection of the corticotropin-releasing factor antagonist α-CRF9-41, bilateral adrenalectomy, and noradrenergic blockade with bretylium did not influence the antisecretory effect of interleukin-1. Polypeptide action was not related to changes in circulating gastrin levels. Human interleukin-1β injected IV also inhibited gastric acid secretion, but the peripheral dose required to induce a significant effect was 103-fold higher than when given centrally. These results show that IC interleukin-1β acts centrally to induce a long-lasting inhibition of gastric acid secretion, and this effect requires the integrity of prostaglandin pathways. These data suggest a possible interaction between the immune and gastrointestinal systems.
