Aim:Blood lipid profiles changed following nonfocused ultrasound treatments for body contouring.The present study elucidates clinical effects of these devices on adipose tissue.Methods:Ultrasound treatments for 5 males and 5 females in a supine position,ages 37-67 years,were applied at 20 KHz and 3.0 W/cm2 in modulated emission.Whole abdomen was treated by an ultrasound handpiece for 30 min followed by a 6-min lymphatic drainage.Waist circumferences at the level of the umbilicus and body weight were measured before and immediately after treatment.Blood lipid profiles including total cholesterol,low-density lipoprotein,high-density lipoprotein,triglyceride(TG),nonesterified fatty acid(NEFA)and lipoprotein-a were measured at baseline,every 10 min during treatment,and 15,30,45,60,75,and 90 min after treatment completion.Results:NEFA showed statistically higher values after 10 min following treatment initiation.Subsequent values remained high despite some fluctuation,reaching a maximum at 90 min.In contrast,TG gradually decreased in concentration until the last measurement,especially for the first 30 min,with statistically significant reduction.Changes in other lipid profiles and lipoprotein-a were not significant.Conclusion:Changes in NEFA concentration were significant following ultrasound treatment,and suggest that metabolism of TGs stored within the adipocytes occurred immediately after treatment initiation.
