药理实验研究表明,黄杨宁能明显延长小鼠因结扎带迷走神经的两侧颈总动脉造成急性脑缺血的存活时间;能减轻大鼠实验性血栓的湿重和干重。提示黄杨宁有保护急性脑缺血及抗血栓形成的作用。

Huangyangning ( HYN ),a preparation made from the extract of Buxus min rophylla Sieb. et Zucc.var.Sinica Rehd. et Wils. could significantly prolong the life span of mice with acute experimental cerebral ischemia caused by bilateral ligation of common carotid arteries with vagaus,and decreased the weight of both dry and wet thrombus. These results showed that HYN possesses a protective action against the formation of thrombus during cerebral ischemia.
