In Vitro	Dalargin (100 µg/mL; 1 h) 在体外减轻庆大霉素诱导的肾上皮细胞死亡[2]。 Cell Viability Assay[2] Cell Line: Kidney cells Concentration: 100 µg/mL Incubation Time: 1 h (prior to treatment with 1.2–2.5 mg/ml gentamicin for 24 h) Result: Reduced kidney cells death.
In Vivo	Dalargin (25, 50 µg/kg; i.p.) 对庆大霉素诱导的大鼠肾损伤显示出肾脏保护作用[2]。 Animal Model: 290-350 g, White male rats[2] Dosage: 25, 50 µg/kg Administration: I.p. (3 h before each gentamicin injection) Result: Mitigated gentamicin-induced acutekidney injury, attenuated ROS generation and oxidative stress, alleviated histopathological changes in a renal tissue.
