对佝偻病动物进行血液生化检查，活性升高的酶是（）

A.脂肪酶

B.肌酸激酶

C.碱性磷酸酶

D.酸性磷酸酶

E.乳酸脱氢酶

答案

参考答案：C

解析：矿物质代谢障碍疾病，佝偻病临诊症状：佝偻病血液学检测出现血清碱性磷酸酶（AKP或ALP）活性明显升高，但血清钙、磷水平则视致病因子而定，如由于磷或维生素D缺乏，则血清无机磷水平可在正常低限时的每100mL3mg水平以下，血清钙水平往往在最后阶段才会降低。X射线检查发现，骨质密度降低，长骨末端呈现"羊毛状"外观，外形上骨的末端凹而扁。剖检主要病变在骨骼，长骨变形、骨端肥大、骨质变软和直径变粗，关节肿大，肋骨与肋软骨结合处肿胀（串珠样肿）。碱性磷酸酶是一种磷酸单酯酶，广泛存在于人体组织和体液中，以骨、肝、乳腺、肠黏膜、肾、胎盘中含量多。【考试科目】《兽医内科学》
