以下为无花果叶提取物与腊梅花提取物在治疗2型糖尿病中的应用试验,
实验动物:健康成年雄性SD大鼠50只,体重在180-200g,大鼠取自蚌埠医学院动物房。随机分成5组,每组50只,设1个无花果叶提取物与腊梅花提取物组(以下简称叶梅组)、1个无花果叶提取物对照组、1个腊梅花提取物对照组,1个正常组,一个模型组。
叶梅组给予高糖高脂饲料(在标准全价混合饲料的基础上添加蔗糖、炼猪油和蛋黄,热能含量21.6kJ/kg),同时在每kg高糖高脂饲料中掺加3-5g无花果叶提取物、2-3g腊梅花提取物,连续喂养1个月,腹腔注射STZ(临用前溶解在pH=4.0的0.1mmol/L柠檬酸缓冲液内,25mg/kg,1次/d,连续2d)。
无花果叶提取物对照组给予高糖高脂饲料(在标准全价混合饲料的基础上添加蔗糖、炼猪油和蛋黄,热能含量21.6kJ/kg),同时在每kg高糖高脂饲料中掺加5-8g无花果叶提取物,连续喂养1个月,腹腔注射STZ(临用前溶解在pH=4.0的0.1mmol/L柠檬酸缓冲液内,25mg/kg,1次/d,连续2d)。
腊梅花提取物对照组给予高糖高脂饲料(在标准全价混合饲料的基础上添加蔗糖、炼猪油和蛋黄,热能含量21.6kJ/kg),同时在每kg高糖高脂饲料中掺加5-8腊梅花提取物,连续喂养1个月,腹腔注射STZ(临用前溶解在pH=4.0的0.1mmol/L柠檬酸缓冲液内,25mg/kg,1次/d,连续2d)。
模型组给予高糖高脂饲料(在标准全价混合饲料的基础上添加蔗糖、炼猪油和蛋黄,热能含量21.6kJ/kg),连续喂养1个月,腹腔注射STZ(临用前溶解在pH=4.0的0.1mmol/L柠檬酸缓冲液内,25mg/kg,1次/d,连续2d)。
正常组普通饲料喂养1个月,再注射等量柠檬酸缓冲液,1次/d,连续2d。
血糖测定:腹腔注射STZ或柠檬酸缓冲液2d后及实验结束时分别进行空腹状态下剪尾取血,测其血糖值,为注射后血糖,4周后处死大鼠测其血糖为终血糖。
叶梅组、无花果叶提取物对照组、腊梅花提取物对照组、正常组血清注射后血糖、终血糖与胰高血糖素检测值如下表:
组别 | 注射后血糖(mmol/L) | 终血糖(mmol/L) | 胰高血糖素(pg/ml) |
叶梅组 | 5.55-5.62 | 4.52-4.56 | 306.9-308.22 |
无花果叶提取物对照组 | 14.47-15.21 | 9.73-9.75 | 382.24-382.39 |
腊梅花提取物对照组 | 16.03-16.15 | 11.34-11.39 | 409.5-409.6 |
模型组 | 17.88-17.96 | 12.59-12.66 | 420.68-420.74 |
正常组 | 5.35-5.38 | 4.27-4.46 | 300.67-300.71 |
由上表可知,在高糖高脂饲料中添加无花果叶提取物与腊梅花提取物的组合相对于单独添加这两者的任意一种,抑制血糖升高的功效明显提升,无花果叶提取物与腊梅花提取物的组合功效相对于无花果叶提取物、腊梅花提取物单独使用功效明显提高。
