Abstract

The invention relates to effective polypeptide parts in Polybia spp. insect venom, and a cardio-cerebral thrombosis use thereof. The effective parts are obtained through a step of dialyzing crude Polybia spp. insect venom through a 25KDa dialysis membrane, and a step of freeze-drying or reduced pressure concentration drying of the above obtained dialysis liquid. A series of pharmacodynamic experiments verify that the effective biotoxin polypeptide parts and transdermal absorption preparations thereof can substantially control the cerebral thrombus, can recover the mobility of cerebral palsy animals, can mitigate the ischemic brain injury, have stronger pharmacodynamic performances than first-line medicines comprising plavix, Xingnaojing and the like, and can be expected to be used for preparing innovative biochemical medicines for preventing and treating cardiovascular and cerebrovascular diseases in order to prevent and treat ischemic cardiocardiovascular diseases, such as myocardial infarction, cardiovascular thrombus, cerebral thrombus, cerebral infarction, acute/chronic cerebral apoplexy, and sequelae caused by cerebral infarction injury, like lateral hemiplegia, hemidysesthesia, hemiopia, facial and lingual paralysis, aphasia and general paralysis.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular, the invention relates to a preparation method and a medical application of an effective fraction of a polypeptide in Polybia spp. insects. The effective part is obtained by dialysis of the crude venom of Vespa heterospira with a 25KDa dialysis membrane, and the eluate is freeze-dried or concentrated and dried under reduced pressure. Through a series of pharmacological and pharmacodynamic experiments in animals, the inventors found that the effective part of the polypeptide has the effect of significantly preventing and treating cerebral thrombosis, restoring the activity ability of cerebral palsy animals, and reducing ischemic brain damage, and can be expected to be used in the preparation of anti-cardiac and cerebrovascular diseases. Vascular diseases include drugs, health care products, medical devices and daily chemicals for ischemic cerebrovascular disease and ischemic cardiovas...
