Collagen sustained-release carrier material for promoting repair of various traumas in oral and maxillofacial regions and method for preparing same

The invention discloses a compound growth factor collagen sustained-release carrier material for promoting repair of various traumas in oral and maxillofacial regions and a method for preparing the same. In order to overcome the defect of poor curative effect existing in the conventional medicaments for treating the traumas of various tissues such as an oral cavity and a face, a bioactive collagen sustained-release material is prepared by combining collagen modified by liposome, chitosan, glycosaminoglycan and the like with one or more of a basic fibroblast growth factor (bFGF), a platelet derived growth factor (PDGF-BB), a vascular endothelial growth factor (VEGF) and a keratinocyte growth factor (KGF). The bioactive collagen sustained-release material is characterized in that: each gram of bioactive collagen sustained-release material contains not less than 10ng of growth factors, and the bioactive collagen sustained-release material has the obvious effect of treating various facial tissue traumas such as tooth extraction wound, oral ulcer, facial nerve injury, mandibular defect and the like. The collagen sustained-release carrier material can continuously release an effective amount of the growth factors to the wound for a long time, fully exert the inducing effect of the growth factors and obviously shorten the time for wound healing so as to fulfill the aim of treatment.

Pesticide water-based low-volume agent and preparation method thereof

The invention discloses a water-based low-volume agent suitable for plant protection unmanned aerial vehicle operation. The water-based low-volume agent is composed of pesticide active pharmaceuticalingredient, solvent, surfactant, anti-freezing agent, anti-volatilization agent and water. The water-based low-volume agent is characterized in that oily solvents of conventional ultralow-volume agents are replaced by a water medium, so that environment risk is lowered; long-chain alcohol is used creatively to enable a monomolecular film to be formed on the surface of each fogdrop when leaving a spraying device, so that volatilization of water molecules in the fogdrops is inhibited, wandering of the fogdrops is reduced, and the fogdrops are enabled to accurately settle on the surfaces of cropsor prevention and control objects. Contact angles formed when the fogdrops wrapped by the long-chain alcohol monomolecular films contact with the surfaces of the crops or prevention and control objects are smaller, so that wettability and penetrability of the fogdrops to the surfaces of targets are enhanced, efficacy of active ingredients is brought into full play, and prevention and control effect of pesticide is improved. In addition, the water-based low-volume agent still can give play to the above advantages during conventional spraying operation.
