Abstract:
Objective To explore the effect of big strain rhodiola injection on levels of leptin and leptin receptor mRNA in serum and liver of rabbit with fatty liver.Methods 120 healthy adult male New Zealand white rabbits were grouped with a random number table method.30 rabbits with normal diet for eight weeks in normal group;90 rabbits in fat group were fed with high fat diet for four weeks to prepare fatty liver model in which 30 rabbits were fed with high-fat diet for four weeks as model group,30 rabbits with high-fat diet and glyburide metformin tablets [150 mg/(kg·d)]for 4 weeks as control group,30 rabbits with high-fat diet and big strain rhodiola injection [40 mg/(kg·d)]for four weeks as experimental group.After the test, levels of serum leptin,hepatic leptin,expression levels of leptin receptor mRNA and levels of liver index were compared among groups.Results Serum leptin and liver leptin in experimental group and control group were all increased to varying degrees,and the serum leptin level [(4.51 ±1.17)ng/mL],liver leptin level [(6.43 ±1.93)ng/mL]of experimental group was lower than that of control group respectively,in which the serum leptin was (7.36 ±1.26)ng/mL and liver leptin was (12.33 ±3.27)ng/mL (P<0.05).Serum leptin and leptin liver receptor mRNA in experimental group and control group were all increased to varying degrees,and the serum leptin mRNA level (0.98 ±0.15),liver mRNA level (1.78 ±0.33)of experimental group was lower than that of control group,in which the mRNA level of serum leptin was (2.57 ±0.29)and liver leptin mRNA levels was (3.31 ±0. 26)(P<0.05).Levels of liver index in experimental group and control group were increased,and liver index of experimental group [(3.98 ±0. 13)%]was lower than that in control group [(4.77 ±0.20)%],and the difference was statistically significant (P<0.05).Conclusion Big strain rhodiola injection could significantly reduce leptin levels in serum and liver of rabbits,reduce expression the leptin receptor mRNA levels and improve liver index,which has guiding significance for the treatment of fatty liver.
