After comparing the experimental group with the control group, it was found that the high-dose group of HGF significantly improved the liver regeneration ability of rats, while the low, medium, and ultra-low dosage groups showed a slight improvement in liver regeneration ability. Through experiments using different routes of administration, such as intramuscular injection, intravenous injection, and gastric lavage, it was found that the gastric lavage and intramuscular injection routes significantly improved the liver regeneration ability of rats, while the intravenous injection had no significant effect. This study has certain guiding significance for exploring the mechanism of HGF affecting liver regeneration ability and finding its application in clinics.【Keywords】Hepatocyte growth factor (HGF); liver regeneration; route; dosage
