(1)本发明药物每天口服 1次, 连续给药 5次, 在 62.5 mg/kg剂量下 就显著减少小鼠悬尾不动时间; 而 A药物需每天需口服 2次, 连续给药 7次, 才能在 125 mg/kg剂量下减少小鼠悬尾不动时间, 因此本发明药物的起效 剂量明显比 A药物低. 日服次数也比 A药物少。
(2)本发明药物每天日服 1次,连续 5次. 在 62.5mg/kg、 125mg/kg、 250 mg / kg剂量下的作用效果呈明显剂量依赖性;而 A药物仅在 125 mg / kg 剂量下才有作用效果, 在 250 mg/kg, 500 mg/kg剂量下无效, 因此本 发明药物治疗抑郁症的疗效更确切。
3、 抗利血平目艮脸下垂抑郁模型试验
为了更进一步证明本发明药物对治疗抑郁症方面的疗效, 还进行了抗 利血平眼脸下垂抑郁模型试验, 通过小鼠连续口服不同剂量本发明药物, 观察各组小鼠中眼脸至少关闭一半以上的动物个数。 评价本发明药物的抗 抑郁疗效。 试验结果见表 5。

以下试验用药为用实施例 1的方法得到的本发明药物, 其商品名为开 郁安神胶嚢, 胶嚢药粉每克相当于原生药 l lg。
1.动物急性毒性试验:
开郁安神胶嚢药粉的 30%稠液给小鼠间隔 6小时连续二次灌胃, 0.4ml/10g体重 ·次, 观察 7日小鼠无死亡, 可知小鼠对该药的最大耐受量 为 24g/kg - d。
结论: 开郁安神胶嚢的 LD5Q>24g/kg . d, 该量约相当于人用量的 1200 倍, 表明该药物对小鼠毒性低。
2.动物长期毒性试验:
开郁安神胶嚢药粉 3.3、 1.9、 0.95g/kg (分别相当于临床常用剂量的 164、 95、 47倍) , 连续灌胃大鼠 90天, 对动物的行为活动、 外观体征、 饲料消 耗和体重增长, 以及外周血象各指标均无明显影响。 血液生化检查 10项指 标与对照组比较无统计学差异(P>0.05 ) 。 解剖观察各主要脏器均无肉眼 可见病变, 主要脏器系数与对照组比较无明显差异(P > 0.05 ) ; 组织病理 检查各动物主要脏器组织均未见异常。
结论: 开郁安神胶嚢药粉剂量 3.3、 1.9、 0.95g/kg连续 90天给药未见引 起动物出现毒性反应; 3.3g/kg剂量连续灌胃给药 90天, 对大鼠各主要脏器、 组织无明显病理影响。
