Abstract

Parathyroid hormone (PTH) regulates calcium (Ca) and phosphate transport. Secondary hyperparathyroidism usually occur in chronic renal failure (CRF), and it is a common complication of CRF in dogs and cats. Twenty one dogs with renal failure were enrolled in this study. Plasma Ca, inorganic phosphorus (iP) and PTH concentrations were measured. Dogs were divided into two groups by the ratio of Ca to iP (Ca/iP$\leq$1; Group I, Ca/iP$\leq$1.5; Group II). The PTH level between sexes ages were not significantly different. The PTH level and Ca/iP between two groups were significantly different (p < 0.0001). In conclusion, The ratio of Ca to iP may be considered as useful surrogator to predict PTH level of dogs with renal failure.

부갑상샘 호르몬 (PTH)은 칼슘과 무기인의 수송을 조절한다. 속발성 부갑상샘 기능항진증은 대개 만성신부전에서 발생하고, 이는 개와 고양이에 있어서 CRF의 일반적인 합병증이다. 신부전을 갖는 21마리의 개가 본 연구에 사용되었다. 공시동물로부터 채혈한 혈액 중 칼슘 (Ca),무기인 (iP), PTH의 농도를 측정하여 칼슘과 무기인의 비율에 따라 두 군으로 분류하였다 (Ca / iP $\leq$ I; 그룹 1, Ca/ip $\geq$ 1.5; 그룹 II). 성과 연령 사이에 부갑상샘 호르몬 수준은 유의성 있는 차이가 없었다. 두 군 사이에 부갑상샘 호르몬 수준과 Ca/P의 비율에는 유의성 (p<0.0001)있는 차이가 나타났다. 결론적으로, 칼슘과 무기인의 비율은 신부전을 갖는 개에서 부갑상샘 호르몬 수준을 예측하기 위한 지표로 이용될 수 있을 것으로 생각된다.
