青鹏膏剂贴敷裸鼠穴区对皮肤内血管和肥大细胞的影响

Influence of Qingpeng plaster on blood vessels and mast cells in skin tissue of channel points of nude mice

目的:通过体表穴区贴敷藏药制剂(青鹏膏剂),观察裸鼠皮肤组织血管和肥大细胞数量的变化,以了解该药物对微循环血流的作用,方法:健康成年裸鼠15只,分为青鹏膏剂贴敷组和对照组。动物贴敷青鹏膏剂7天后,分别在两组动物的背部取涂药部位(以第4胸椎为中心)和相应未涂药部位皮肤组织,进行切片染色观察。结果:在涂青鹏膏剂的真皮深层以下的组织内明显可见扩张的血管和肥大细胞数量数量增多。在同体对照或对照组的皮肤组织内,虽也见少量扩张的血管,但明显少于涂药的皮肤组织内的血管数量。统计学处理结果显示青鹏膏剂组涂药部位的皮肤组织内血管数量和肥大细胞数量,均明显多于同体未涂药部位和对照组的数量,有非常显著性差异(P<0.001)。结论:青鹏膏剂对涂药部位皮肤组织内的血管明显有扩张作用和促肥大细胞聚集作用。

Objective： To investigate the changes in the numbers of blood vessels and mast cells, which is relative to blood microcirculation in skin, during Qingpeng plaster （ZANG medicine） being applied to the skin surface of nude mice. Method： Fifteen healthy adult nude mice were divided into Qingpeng plaster group and the control group. The sites of skin tissues stuck with the plaster or with control plaster were selected after 7 days treated, and then all the slices stained and observed. Result： The numbers of the vessels and the mast cells increased in the dermal tissue of Qingpeng paster group. Although there were a few dilated blood vessels in the control group, but the numbers of the vessels and the mast cells were obviously less than those of the Qingpeng plaster group. Statistical analysis showed that there was a significant difference （P 〈0. 001 ） between tow groups. Conclusion： Qingpeng plaster can cause obvious vascular dilatation and promot mast cells aggregation in the Qingpeng plaster stuck parts of the skin tissue.
