Abstract

Wound-healing dipyridamole- and papaverine-based aerosols (D1/D2) as activators of the accumulation of cyclic adenosine monophosphate are promising drugs that can accelerate wound healing in wound processes of various origins. 128 rats were used in the study, including 38 in a pharmacological experiment on a model of stencil wounds and 90 in an experiment that studied the effect of spray on the number of CD34 cells in the blood of rats with chemically induced immunodeficiency. Immunodeficiency was caused by the fivefold administration of cyclophosphamide and prednisone. The expression level of CD34 was determined using flow cytofluorimeter. Dipyridamole- and papaverine-based aerosols of two compositions (with and without ascorbic acid) have pronounced reparative properties, significantly accelerating epithelialization and healing of stencil wounds in rats. In terms of this type of action, they are somewhat superior to dexpanthenol. Dipyridamole- and papaverine-based aerosols have the ability to produce beneficial effect on the entire body's immune system by stimulating the division of pluripotent CD34 cells. The combined effect of papaverine and dipyridamole on tissues leads to selective stimulation of the division of pluripotent cells in the wound, and contributes to a six-fold acceleration of restoration of the animal's immune system after induced immunodeficiency. Topical application of D1/D2 aerosol samples on the skin of rats contributed to a statistically significant acceleration of regeneration processes. In terms of the appearance of granulations and epithelialization of wounds, D1/D2 aerosols were superior to dexpanthenol ointment.

摘要

作为环磷酸腺苷积累激活剂的基于双嘧达莫和罂粟碱的伤口愈合气雾剂(D1/D2)是很有前景的药物,可加速各种病因伤口愈合过程中的伤口愈合。该研究使用了128只大鼠,其中38只用于模板伤口模型的药理实验,90只用于研究喷雾对化学诱导免疫缺陷大鼠血液中CD34细胞数量影响的实验。免疫缺陷是由五次给予环磷酰胺和泼尼松引起的。使用流式细胞荧光仪测定CD34的表达水平。两种成分(含和不含抗坏血酸)的基于双嘧达莫和罂粟碱的气雾剂具有显著的修复特性,可显著加速大鼠模板伤口的上皮形成和愈合。就这种作用类型而言,它们在某种程度上优于泛醇。基于双嘧达莫和罂粟碱的气雾剂能够通过刺激多能CD34细胞的分裂对全身免疫系统产生有益作用。罂粟碱和双嘧达莫对组织的联合作用导致伤口中多能细胞分裂的选择性刺激,并有助于诱导免疫缺陷后动物免疫系统恢复加速六倍。在大鼠皮肤上局部应用D1/D2气雾剂样品有助于再生过程在统计学上显著加速。就伤口的肉芽出现和上皮形成而言,D1/D2气雾剂优于泛醇软膏。
