The aim of this study was to determine whether exposure to low doses of DON leads to changes in serum hematological and biochemical profiles. In the experiment, pre-pubertal gilts (with body weight of up to 25 kg) were administered DON per os at a daily dose of 12 μg/kg BW (group E, n=18) or a placebo (group C, n=21) over a period of 42 days. Blood for analysis was sampled seven times at weekly intervals. Minor, but statistically significant changes were observed in selected indicators, particularly in weeks 2 and 3 in values of biochemical parameters such AlAT, AspAT, Pin and Fe, and in values of hematological parameters such as RBC, MCV, MCHC, PLT, MPV, WBC, neutrophil, eosinophil, lymphocyte and monocyte counts. In group E, a decreasing trend of the values was observed in most cases, except for RBC, PLT, eosinophil, lymphocyte and monocyte counts. Similar results were obtained in the last two weeks of the experiment. Initially, exposure to DON has a stimulating effect, which is eliminated when adaptive mechanisms are triggered. The results of the study indicate that the intensity of biotransformation processes varies subjected to the body's energy resources.
本研究的目的是确定暴露于低剂量脱氧雪腐镰刀菌烯醇(DON)是否会导致血清血液学和生化指标发生变化。在实验中,对青春期前的小母猪(体重最高达25千克),在42天的时间里,每天经口给予12微克/千克体重的DON(E组,n = 18)或安慰剂(C组,n = 21)。每隔一周采集一次血液样本进行分析,共采集七次。在选定指标中观察到了微小但具有统计学意义的变化,特别是在第2周和第3周,谷丙转氨酶(AlAT)、谷草转氨酶(AspAT)、磷(Pin)和铁(Fe)等生化参数值以及红细胞(RBC)、平均红细胞体积(MCV)、平均红细胞血红蛋白浓度(MCHC)、血小板(PLT)、平均血小板体积(MPV)、白细胞(WBC)、中性粒细胞、嗜酸性粒细胞、淋巴细胞和单核细胞计数等血液学参数值出现了变化。在E组中,除红细胞、血小板、嗜酸性粒细胞、淋巴细胞和单核细胞计数外,大多数情况下观察到数值呈下降趋势。在实验的最后两周也得到了类似结果。最初,暴露于DON有刺激作用,但当触发适应性机制时这种作用就会消除。研究结果表明,生物转化过程的强度因身体的能量资源而异。
