조수열(Soo Yeul Cho),안춘길(Choon Kil Ahn),정재홍(Jae Hong Jeung) 한국식품영양과학회 1983 한국식품영양과학회지 Vol.12 No.3
無機質 相互間에 미치는 영향을 檢討코저 CdCl₂ 溶液을 飮料水(0, 5, 10, 20, 40ppm)로하여 白鼠에게 4週間 投與하였을 때 血液, 硬骨 및 齒牙 중의 無機成分含量을 測定 考察한 結果는 다음과 같다.<br/> 1. Cd給與水準이 높아짐에 따라 현저한 體重減少와 낮은 飼料效率을 나타내었다.<br/> 2. 單位體重 당 臟器重量은 肝臟이 增加했는 반면에 다른 臟器들은 아무런 영향을 받지 않는다.<br/> 3. 血淸 중의 Cd含量은 40ppm群에서 현저하게 높았으나, Fe, Cu, Zn 및 Mg含量은 減少하였다.<br/> 4. 硬骨 중의 Cd含量과 P含量은 40ppm群에서 많아졌으나, Fe, Cu, Zn, Mg, Ca含量 및 灰分含量은 Cd給與水準을 높일수록 減少하는 傾向을 나타내었다.<br/> 5. 齒牙 중의 Cd含量은 血液과 硬骨에서 보다 훨씬 많았으며, Fe, Cu, Zn 및 P含量은 Cd給與水準을 높일수록 減少하는 傾向을 나타내었고, Mg含量과 灰分含量은 增加하는 傾向을 나타내었다. This experiment was undertaken to determine the effect of several levels of cadmium on growth and some mineral concentrations in the serum, tibia and teeth of rats.<br/> The results obtained are summarized as follows.<br/> Growth rate was significantly decreased as the feeding level of cadmium increased, especially body weight in the 40 ppm level was greatly reduced than that of initial body weight.<br/> The weight of liver was increased in 40 ppm group as a result of edema. But the weight of kidney, heart, spleen, lung and testis was not affected.<br/> The cadmium concentration of serum was higher in rats receiving 40ppm than that of other levels, and the concentrations of iron, zinc, copper, magnesium and calcium were decreased as the cadmium content of drinking water increased.<br/> The cadmium and phosphorus contents of tibia were greatly high in the 40ppm level, but the content of iron, copper, zinc, magnesium, calcium and ash tended to be decreased with increasing level of cadmium.<br/> The cadmium concentration of teeth was predominantly high compared with that of the serum and tibia. Also, the concentration of iron, copper and zinc tended to be dedrased with increasing cadmium level, but the contents of magnesium, calcium and ash tended to be increased.
