Type B plant had two kinds of color roots, the rufous roots belonged to type A tissue, the yellow roots belonged to type C tissue through the SSR identification.

深州杨B型的叶柄、叶主脉、芽、侧枝茎尖、韧皮部、木质部同时检测到深州杨A、C型两种成分存在，属于嵌合组织，B型叶肉及细叶脉中检测不到深州杨C型成分，属于深州杨A型纯合组织；深州杨B型植株的地下部分含有红褐色和土黄色两种根，经检测，红褐色根是属于深州杨A型的纯合组织，土黄色根是属于深州杨C型的纯合组织。

Prior administration of "Styrax Pill for Coronary Disease" proper (6 components viz., styrax liquidus, Borneolum, Lignum santali, Aristolochia, Olibanum and Cinnabaris) or the mixture of Styrax liquidus, Borneolum, Lignum Santali and Olibanum to mice prolonged the survival time of the animals subjected to low pressure hypoxia. Styrax liquidus and Borneolum administered separately showed the same effect, whereas none of the other four components showed significant protection.

用小鼠耐缺氧试验和麻醉狗冠状窦血流量及心脏动-静脉血氧差(MA-VO_2)的实验研究冠心苏合丸及其成分的作用，发现：(1)冠心苏合丸能延长小鼠耐缺氧的时间；(2)冠心苏合丸能使心肌梗塞狗的CSF回升，减少心率和MA-VO_2，对非心肌梗塞狗不能提高CSF但亦能减少心率和MA-VO_2；(3)在本实验条件下，苏合香脂和冰片似为冠心苏合丸中起作用的两个成分，其余成分如檀香、青木香、乳香或其油均未能证实其效果。
