Abstract：To compare and analyze the tensile mechanical properties of the middle cerebral artery in Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats(SHR), which can provide the basis for the prevention of hypertension.We carryed out the experiment of the longitudinal tensile test with the speed of 0.5mm/Min.The samples were from the middle cerebral artery of 5 month old male rats, 20 rats in each group with the normal WKY and SHR rats.The tensile maximum stress, maximum strain, elastic strain limit of wky rat′s middle cerebral artery y was greater than that of male spontaneously hypertensive rats (P<0.05).The cerebral artery elastic modulus value of SHR male rats was greater than that of male WKY rats (P<0.05).There are different tensile mechanical properties between WKY rats and SHR ones,and the changes in arterial tensile mechanical properties of SHR in the rat brain.
