目的　探討在細胞因子與大鼠胰島細胞共同培養過程中，誘導型一氧化氮合酶(iNOS)抑制劑氨基胍對胰島細胞功能和存活的影響及其機理。
方法　分離純化大鼠胰島，進行胰島細胞培養。根據培養基中是否加入氨基胍或細胞因子IL-1β和TNF-α，按隨機對照原則分為空白對照組(完全培養基)、細胞因子組(加IL-1β和TNF-α)、氨基胍組(加氨基胍)及氨基胍＋細胞因子組(加氨基胍及細胞因子)。檢測指標包括：培養液中NO水平、胰島組織中iNOS活性、胰島細胞存活情況（丫啶橙/溴乙錠染色）、胰島細胞凋亡情況（TUNEL法）及胰島功能（胰島素釋放試驗）。
結果　與空白對照組比較,細胞因子組大鼠胰島組織中iNOS的活性明顯提高，培養液中NO的水平明顯上升，同時胰島細胞的存活率下降，大量細胞凋亡，胰島素分泌明顯減少(P＜0.01)。與細胞因子組比較,氨基胍＋細胞因子組的iNOS的活性〔（3.17±0.51） U/ml比（38.93±4.72） U/ml〕及NO水平〔（50.5±10.4） μmol/L比（313.0±35.4） μmol/L〕明顯下降，胰島細胞存活率活明顯升高〔（72.73±3.14）%比（57.07±5.07）%〕，凋亡率明顯下降〔（20.11±8.48）%比（41.17±6.87）%〕，胰島素分泌指數明顯升高(3.50±0.27比1.96±0.19),差異均有統計學意義(P＜0.01)。
結論　氨基胍通過抑制iNOS活性，控制NO過量產生，從而減輕細胞因子對胰島的損害，改善胰島的存活與功能。
