Abstract: OBJECTIVE This study aimed to explore whether exposure to ceftriaxone during early life could influences glucose and lipid metabolism of high fat diet-induced mice. METHODS Total 48 of female BALB/c aged 2 week old were randomly divided into control group(treated with saline),antibiotic group(treated with100 mg/kg ceftriaxone), high-fat diet group(treated with saline) and combined action group(treated with 100 mg/kg ceftriaxone)(n=12), respectively to stop gavage 2 weeks later. Then high-fat diet group and combined action group were fed with high-fat diet for 12 weeks. Fasting blood glucose(FBG) and oral glucose tolerance test were conducted in the last week. Serum total cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), fasting insulin, leptin and TG, TC in liver were also measured. Furthermore, homeostasis model assessment of insulin resistance(HOMA-IR) was calculated from FBG and insulin. RESULTS Compared with normal chow diet, high-fat diet impaired oral glucose tolerance and increased the levels of abdominal adipose tissue, FBG, HOMA-IR, lips in serum and liver and leptin(P<0.05).The oral administration of ceftriaxone in early life impaired oral glucose tolerance and increased the levels of abdominal adipose tissue, FBG and TG in liver(P<0.05). In addition, early ceftriaxone intervention could enhance the impaired glucose tolerance, the increasing FBG, insulin resistance and liver lipids associated with high-fat diet(P<0.05). CONCLUSION Early ceftriaxone intervention not only significantly increases the level of abdominal adipose tissue, FBG, insulin resistance and liver lipids, but also enhances glycolipid metabolic disorders induced by high-fat diet. These result suggest that the exposure to antibiotics in the early life might increase the sensitivity of host animal to high fat diet induced abnormal glycolipid metabolism late.
