The study was undertaken to investigate the acute and subchronic hypoglycemic effects of an ethyl acetate (EtAc) extract of red sour cherry (Prunus cerasus) pulps and seeds in alloxan-induced diabetic mice.
The Prunus cerasus pulp (PPc) and seed (SPc) EtAc extract s were IP-administered to the mice in doses of 100, 150 and 200mg/kgbody weight (b.w.) for acute study (6h) and subchronic study (8days). The in vivo effects of (PPc) and (SPc) EtAc extracts were assessed through blood glucose levels (BGL), changes in body weight as well as antioxidant enzyme activity. At the end of the study, animals were sacrificed for obtaining pancreatic tissues samples to assess histopathological changes in pancreas of control and alloxan-induced mice.
Acute administration of either PPc or SPc for 6h at all tested doses, significantly (P≤0.05) decreased BGL as compared with vehicle treated diabetic control (DIA CTRL) group with PPc showing more significant acute antidiabetic activity than those of SPc. In addition, subchronic administration of PPc has shown more significant (P≤0.05) amelioration of hyperglycemia, weight-loss and oxidative stress at all doses compared to SPc administration. Histologically, treatment with PPc and SPc showed significant pancreatic cell regeneration compared to diabetic controls.
Results indicated that ethyl acetate extracts of Prunus cerasus pulps and seeds promote acute and subchronic hypoglycaemic effects in alloxan-induced diabetic mice with pulp extracts having a more pronounced effect.
本研究旨在探讨酸樱桃(欧洲酸樱桃)果肉和种子的乙酸乙酯提取物对四氧嘧啶诱导的糖尿病小鼠的急性和亚慢性降血糖作用。
将酸樱桃果肉(PPc)和种子(SPc)的乙酸乙酯提取物以100、150和200mg/kg体重(b.w.)的剂量腹腔注射给小鼠,用于急性研究(6小时)和亚慢性研究(8天)。通过血糖水平(BGL)、体重变化以及抗氧化酶活性评估(PPc)和(SPc)乙酸乙酯提取物的体内作用。在研究结束时,处死动物以获取胰腺组织样本,评估对照组和四氧嘧啶诱导的小鼠胰腺的组织病理学变化。
在所有测试剂量下,PPc或SPc急性给药6小时后,与溶剂处理的糖尿病对照组(DIA CTRL)相比,血糖水平显著(P≤0.05)降低,PPc的急性抗糖尿病活性比SPc更显著。此外,与SPc给药相比,PPc亚慢性给药在所有剂量下均显示出更显著(P≤0.05)的高血糖改善、体重减轻和氧化应激减轻。组织学上,与糖尿病对照组相比,PPc和SPc处理显示出显著的胰腺细胞再生。
结果表明,酸樱桃果肉和种子的乙酸乙酯提取物对四氧嘧啶诱导的糖尿病小鼠具有急性和亚慢性降血糖作用,果肉提取物的作用更明显。
