Fig. 4From: Exposure to PM2.5 affects blood lipid levels in asthmatic rats through notch signaling pathwayEffect of different doses of PM2.5 on serum lipid levels in normal rats (n = 6 animals/each group). a Total cholesterol (TC) level; b Low density lipoprotein cholesterol (LDL) level; c Triglyceride (TG) level; d High density lipoprotein cholesterol (HDL) level. ▲Statistically significant difference compared with LD (p < 0.05); * statistically significant difference compared with BC (p < 0.05). Abbreviation: BC: blank control group; LD: low dose (PM2.5 1.5 mg/kg) group; MD: middle dose (PM2.5 7.5 mg/kg) group; HD: high dose (PM2.5 37.5 mg/kg) groupBack to article page
