Protocol
Diosmetin is dissolved in DMSO which is maintained at a constant concentration in control samples (2%). HepG2 cells are maintained in a humidified atmosphere of 5% CO2 at 37°C, and cultured in RPMI-1640 medium supplemented with 10% (v/v) fetal bovine serum, 100 U/mL penicillin and 100 U/mL streptomycin. HepG2 cell density is adjusted to 2×104 cells/100 μL, and the cells are seeded into 96-well plates and placed in an incubator overnight (37°C in 5% CO2) to allow for attachment and recovery. MTT analyses are performed. Briefly, cells are pretreated with 5, 10, 15 and 20 μg/mL diosmetin for 24 h. A total of 20 μL MTT solution (5 mg/mL in PBS) solution is transferred to each well to yield a final 120 μL/well and to separate wells a total of 10 μL CCK8 (5 mg/mL in PBS) is transferred. The plates are incubated for 4 h at 37°C in 5% CO2 and the absorbance is recorded at wavelengths of 595 nm and 450 nm, respectively. The half maximal inhibitory concentration (IC50) of diosmetin is calculated[1].

Experimental acute pancreatitis is induced in mice by seven intraperitoneal injection of cerulein (50 μg/kg) at hourly intervals. Diosmetin (100 mg/kg) or vehicle is pretreated 2 h before the first cerulein injection. After 6 h, 9 h, 12 h of the first cerulein injection, the severity of acute pancreatitis is evaluated biochemically and morphologically[2].
