维生素D对低磷酸盐血症奶牛细胞因子的影响

试验选择安达市先锋乡奶牛场部分低血磷的奶牛为试验对象 ,经喂饲高磷牧草并添加维生素Ds,检测血清细胞因子 (IL - 1、IL - 6 )的动态变化 ,揭示维生素D对低磷酸盐血症奶牛细胞因子的影响。研究结果表明 :当奶牛发生低磷酸盐血症时IL - 1、IL - 6含量升高     

Phosphorus and phosphate metabolism in veterinary patients

Objective: To review phosphorus and phosphate metabolism and the importance of phosphate abnormalities in veterinary patients. Data sources: A review of recent human and veterinary medical literature. Human data synthesis: There is a significant amount of original research on human patients with phosphate abnormalities. Hypophosphatemia has been studied in patients with diabetic ketoacidosis (DKA), head trauma, refeeding syndrome, hypothermia and in ventilator patients that fail to wean. Hyperphosphatemia has been studied in patients with renal failure and malignancy. Phosphate levels have also been evaluated for prognostic value in sepsis and acute liver failure. Veterinary data synthesis: Although animal models were used in early experimental research, fewer studies have been published on the effects of phosphate abnormalities in veterinary patients. Hypophosphatemia has been studied in animals with DKA, with refeeding syndrome and with hyperparathyroidism. Hyperphosphatemia has been studied in animals with renal failure and with secondary hypoparathyroidism. Conclusion: Phosphorus and phosphate are important in many biological functions. This paper is a review of their role in normal metabolism and the clinical importance of phosphate imbalances for our emergency and critical care patients.     

低磷奶牛血清某些生化指标变化

为进一步研究低磷引起血红蛋白尿症的发病机理,对低磷奶牛血清生化指标进行了检测。采用分组对比的方法,测定各组奶牛血清若干生化指标。结果,血尿组,低磷组,对照组血清无机磷含量差异显著。     

安达地区奶牛低磷酸盐血症调查研究报告

１９９０年以来，安达及周围地区十几个市县的奶牛常不同程度的发生低磷酸盐血症。为查找病因、探讨发生机理、确定诊断方法及防治措施，我们从１９９４年开始，连续三年对安达地区养牛户奶牛的低磷酸盐血症进行流行病学调查、临床检查，并测定了病牛和假定健康牛的血清无机磷、钙、镁、碱性磷酸酶、羟膊氨酸及饲料和土壤磷含量。结果表明安达地区土壤含磷量低，导致植物性饲料的磷含量不足，是奶牛发生低磷酸盐血症的主要原因。流行情况和降雨量有关。临床多数表现为骨软症型，少数表现为血红蛋白尿型和混合型。饲料补磷和土壤增施磷肥为主要防治措施
