Methods The rabbit model with hyperhomocysteinemia was established by L-methionine subcutaneouse injection. The changes of white microthrombus and microvascular diameter in pia mater microvessel were observed by using cranial window method and closed microcirculation detection system, The concentration of Hcy was detected by high performance liquid, The level of von Willebrand factor, endothelin-1 (ET-1) were assayed by ELISA. The content of NO was measured by nitrate reduction method. Meanwhile, the relationship between the changes of microvascular diameter and blood concentration ET-1, NO was analyzed.
