Replacing sucrose with non-caloric sweeteners is an approach to avoid overweight and diabetes development. Non-caloric sweeteners are classified into either artificial as sucralose or natural as stevia. Both of them have been approved by FDA, but the effects of their chronic consumption are controversial. The present study aimed to evaluate the effects of these two sweeteners, in male and female albino mice, on different blood biochemical parameters, enzymes activities and immunological parameters after 8 and 16 weeks of sweeteners administration. 40.5 mg/ml of sucrose, 5.2 mg/ml of sucralose and 4.2 mg/ml of stevia were dissolved individually in distilled water. Mice were administrated by sweetener's solution for 5 h daily. Male and female mice showed a preference for water consumption with sucralose or stevia. Both of the two sweeteners significantly reduced the hemoglobin level, HCT%, RBCs and WBCs count. After 18 weeks, significant elevations in liver and kidney function enzymes were observed in male and female mice administrated with both non-caloric sweeteners. Histopathological examination in sucralose and stevia administrated groups confirmed the biochemical results; where it revealed a severe damage in liver and kidney sections. While, sucrose administration elevated, only, the levels of ALT, AST and cholesterol in male mice. A vigorous elevation in levels of different immunoglobulin (IgG, IgE and IgA) and pro-inflammatory cytokines (IL-6 and -8), that was accompanied by a significant reduction in level of anti-inflammatory cytokine IL-10, was observed in male and female mice groups administrated with sucralose or stevia. On the other hand, sucrose administration led to an elevation in IgA and reduction in IL-10 levels.
用无热量甜味剂替代蔗糖是一种避免超重和预防糖尿病的方法。无热量甜味剂分为人工合成的(如三氯蔗糖)和天然的(如甜菊糖苷)。它们都已获得美国食品药品监督管理局(FDA)的批准,但长期食用它们的影响存在争议。本研究旨在评估这两种甜味剂在雄性和雌性白化小鼠中,连续给药8周和16周后,对不同血液生化参数、酶活性和免疫参数的影响。将40.5毫克/毫升的蔗糖、5.2毫克/毫升的三氯蔗糖和4.2毫克/毫升的甜菊糖苷分别溶解于蒸馏水中。小鼠每天饮用甜味剂溶液5小时。雄性和雌性小鼠都表现出对饮用含三氯蔗糖或甜菊糖苷的水有偏好。两种甜味剂均显著降低了血红蛋白水平、血细胞比容(HCT)%、红细胞(RBCs)和白细胞(WBCs)计数。18周后,在给予两种无热量甜味剂的雄性和雌性小鼠中,观察到肝肾功能酶显著升高。三氯蔗糖和甜菊糖苷给药组的组织病理学检查证实了生化结果;结果显示肝和肾切片有严重损伤。而给予蔗糖仅使雄性小鼠的谷丙转氨酶(ALT)、谷草转氨酶(AST)和胆固醇水平升高。在给予三氯蔗糖或甜菊糖苷的雄性和雌性小鼠组中,观察到不同免疫球蛋白(IgG、IgE和IgA)和促炎细胞因子(IL-6和IL-8)水平显著升高,同时抗炎细胞因子IL-10水平显著降低。另一方面,给予蔗糖导致IgA升高和IL-10水平降低。
