摘要
目的 研究 3种方法取脂及 4种压力抽脂对脂肪细胞损伤的影响程度 ,以指导临床。方法 分别采用剪刀剪碎、2 2号特制钝头侧孔脂肪抽吸针头注射器抽吸、吸管 (直径 4mm无菌吸引头分别以-2 5、-5 0、-76及 -10 1kPa)抽吸脂肪 ,所得标本做成石蜡切片 ,Van Gieson染色 ,镜下观察脂肪细胞的损伤程度。结果 剪碎法、注射器法及吸管法 (均值 )取脂对脂肪细胞的损伤率分别为 ( 8.6± 1.8) %、( 15 .7±2 .4) %及 ( 38.4± 4.2 ) % ;吸管法中 4种压力对脂肪细胞的损伤率分别为 ( 2 6.3± 2 .5 ) %、( 2 7.6± 2 .6) %、( 36.8± 3.5 ) %及 ( 68.9± 7.4) %。 3种方法相互间差异均有显著性意义 ,4种压力中 ,除 -2 5kPa与 -5 0kPa组间差异无显著意义外 ,>-5 0kPa各组相互间差异均有显著性意义。结论 3种方法取脂对脂肪细胞的损伤程度不同 ,剪刀剪碎法最轻 ,注射器法居中 ,吸管法最重。压力不同对脂肪细胞的损伤程度亦不同 ,当压力 <-5 0kPa时 ,对脂肪细胞的损伤程度差异无显著意义 ,压力 >-5 0kPa时 ,随着压力增大 ,脂肪细胞损伤程度增加。
Objective To study the injury percentage of fat cells from human bodies by three methods and four suctioned negative pressures. Methods Fat tissue was removed from lower abdomen by excision, aspiration and suction. A pair of sharp scissors was used to cut excisied adipose tissue into 3mm diameter fat particles. A 4 mm diameter pipet and four negative pressures (-25 kPa, -50 kPa, -76 kPa and -101 kPa) were used to suction fat tissue. The samples were fixed in 10 % buffered formalin, stained with hematoxylin eosin and Wilder's silver methods. The fat cells were observed under light microscope. Results The injury percentage of fat cells removed by three methods were (8.6± 1.8) %, (15.7±2.4) % and (38.4±4.2) % respectively;all of them had significant differences among them. The injury percents of fat cells suctioned under-25 kPa,-50 kPa, -76 kPa and -101 kPa were (26.3±2.5) %, (27.6± 2.6) %, (36.8±3.5) % and (68.9±7.4) % respectively. There were no significant differences between the first two but there were among other groups. Conclusions The injury extent of fat cells has significant differences among 3 methods, in which the excision is the least and the suction is the most serious. The injury extent of fat cells has no significant differences when the pressure is lower than -25 kPa. But when the pressure is higher than -50 kPa, the higher the pressure, the more serious the injury extent.
