Definitions
- the invention belongs to the fields of biomedicine, functional food and the like, and particularly relates to the application of a superoxide dismutase.
- the fatty liver is alcoholic fatty liver or nonalcoholic fatty liver.
- the medicament is administered by the oral, injection or gavage route.
- the injection is intravenous or intraperitoneal.
- the pharmaceutical dosage form is a tablet, a capsule, a powder, an injection or an aerosol.
- the manganese type high stability superoxide dismutase provided by the invention can effectively reduce the superoxide level, and is suitable for various types of fatty liver such as alcoholic fatty liver, nonalcoholic fatty liver, fatty liver accompanied by metabolic syndrome. Have a good therapeutic effect.
- Figure 3A shows the weight comparison between the high fat diet group and the MS-SOD treatment group
- Figure 4A shows plasma ethanol concentration
- Figure 4B shows liver alcohol dehydrogenase (Adh1) and cytochrome P4502E1 (Cyp2e1) mRNA levels;
- Figure 5D is a fatty liver score
- FIG. 5G shows the results of a glucose tolerance test (GTT).
- Figure 5K shows plasma endotoxin lipopolysaccharide levels.
- High-fat+MS-SOD group (HFD+MS-SOD): fed with high-fat diet for 18 weeks, and starting from the 8th week, the mice were given MS-SOD for 3U/g body weight. Each 0.1ml, once a day, up to 18 weeks. MS-SOD was from the article of Example 1 above.
- High fat feed component add lard based on low fat feed.
- Mn-SOD manganese-type superoxide dismutase
- CuZn-SOD copper-zinc superoxide dismutase
- the test was carried out using the superoxide detection kit of Shanghai Biyuntian Biotechnology Co., Ltd. Kit principle: The superoxide can be detected by using superoxide to reduce the water-soluble tetrazolium-1 (WST-1) to produce soluble colored substances.
- WST-1 water-soluble tetrazolium-1
- MS-SOD gavage group the mice were intragastrically administered orally (oral) at a dose of 6 U/g body weight per day, and the amount of gavage was 0.1 ml per day, once a day for 7 days;
- MS-SOD intraperitoneal injection group mice were intraperitoneally injected with 6 U/g body weight per day, the injection volume was 0.1 ml per time, 1 time/day, and continuous injection for 7 days.
- mice Sixty-five-year-old male C57 mice (purchased from the Guangdong Experimental Animal Center) were housed in an SPF environment and divided into three groups:
- Control group The Lieber-DeCarli alcohol-free liquid diet for 9 weeks;
- Model control group (alcohol, Alc): The Lieber-DeCarli alcoholic liquid diet for 9 weeks;
- MS-SOD treatment group (Alc+SOD): The Lieber-DeCarli alcoholic liquid diet for 9 weeks, while gavage MS-SOD (3 U/g body weight).
- the MS-SOD treatment group was intragastrically administered with MS-SOD solution (3 U/g body weight), the amount of gastric perfusion was 0.1 ml per time, once per day, and the gavage period was 9 weeks.
- the blank control group and the model control group were intragastrically administrated with sterile water, and the amount, frequency and cycle of gavage were the same as those in the treatment group.
- fresh feces were collected every 9 am at 9 am and stored at -80 °C.
- the plasma ALT/AST levels were monitored by eyelid blood collection.
- the tissues were dissected and frozen at -80 °C.
- mice were induced for eight weeks in the diet of liber DeCarli. Ethanol metabolism is not affected by MS-SOD, such as plasma ethanol levels and liver alcohol dehydrogenase, cytochrome p4502E1 expression ( Figures 4A, 4B).
- MS-SOD such as plasma ethanol levels and liver alcohol dehydrogenase, cytochrome p4502E1 expression
- the liver weight/body weight ratio was significantly higher in the alcohol group and slightly lower in the alcohol + SOD group (Fig. 4C).
- plasma alanine aminotransferase levels were significantly reduced in the alcohol + SOD group (Fig. 4D).
- hepatic lipid accumulation and liver ccl2 expression were significantly reduced in the MS-SOD group (Fig. 4E-H).
- MS-SOD can improve the symptoms of intestinal flora imbalance, intestinal leakage and hepatic steatosis caused by alcohol feeding.
- Example 6 MS-SOD alleviates the symptoms of fatty liver and metabolic syndrome in mouse genetically deleted leptin (ob/ob mice)
- ITT Insulin tolerance test
- MS-SOD treatment significantly changed the composition of the intestinal flora (Fig. 5I).
- Fig. 5I By monitoring the levels of fecal albumin and plasma endotoxin lipopolysaccharide, it was found that MS-SOD significantly improved intestinal leakage and translocation of bacterial products (Fig. 5J, K).
- MS-SOD relieves the symptoms of fatty liver and metabolic disorders in the OB/OB mouse model.
