BMD (A) and BMC (B) at the femur neck and lumbar vertebra. BMD and BMC at the lumbar vertebrae and femur in the 4-month smoke-exposed rats were significantly lower than that in other groups. Significantly higher BMD and BMC at the femur neck and lumbar vertebra were founded in the 150 and 300 mg/kg/d EPF group receiving passive smoking compared to the control group. Mean ± SD (n = 10 in each group). *P < 0.05 compared to smoke-exposed rats; #
P < 0.05 compared to controls.
