The purpose of this study is to investigate the effect of raw Cassia tora 1., powder added-diets on reducing cadmium accumulatin in rats. The experimental animals were Sprague-Dawley family(♂. 4 weeks) which was classified into normal group ('N, compared group CS, Cd-added group C1 and groups C2, C3, C4 in which 0.5, 1.0 and 1.5% of the Cassia tora L. powder are added. respectively. The growth rate and food efficiency ratio, and the amounts of accumulated cadmium in rats for 8 weeks were measured and analyzed.
The results are as follows;
1. The rates of weight gain decreased in the order of C3>C2>C4>Cn>Cs>C1 groups. and C1 group to which only cadmium water had been fed was the lowest among them. The correlation between groups C1 and C3 was significantly different at the 1% level.
2. Food efficiency ratio(FER) decreased in the order of C3>C2>Cs>Cn>C4>C1. and the FERs of C3, C2, Cs, Cn and C4 are greater than that of C1 by 22.87, 19.89, 18.54, 14.20 and 13.17% respectively.
3. As for the Cassia tora L. powder-added groups, the amounts of cadimum accumulated in organs and tissues, that is, the brain, heart, spleen, liver, lungs, testicles, kindey, femoral muscale and leg bones were 0.45±0.04 to 0.83±0.04, 1.68±0.02 to 2.16±0.02, 3.26±0.05 to 4.62±0.27, 37.82±0.09 to 47.71±0.73, 1.07±0.10 to 1.66±0.04, 1.04±0.06 to 1.24±0.08, 36.79±0.20 to 39.61±0.53, 0.87±0.02 to 1.00±0.02 and 0.65±0.17 to 1.27±0.06 ㎍/g respectively.
4. The accumulated Cd content for C4 was the lowest among Cassia tora L. powder-added groups. When the results for C4 are compared with those for C1, it is observed that each cadmium content accumulated in the brain, heart, spleen, liver, lungs, testicles, kidney, femoral muscle and leg bones is dropped by 49.03, 22.56, 36.02, 35.75, 41.75, 36.20, 37.00, 22.77 and 56.67%, respectively, On the other hand, the accumulated Cd contest increased in the order of brain < leg bones < femoral muscle > testicles < lungs < heart < spleen < kidney < liver.
5. The average Cd accumulation rate in organs and tissues relative to the total Cd intake was 7.14% for C1, while they are 4.91, 4.81 and 4.50% for Cassia tora L. powder-added groups C2, C3 and C4, respectively.
6. The Cd content accumulated in the hair for C1 was the highest, and those for Cassia tora L. powder-added groups gradually increased until 6 weeks and decreased after that. 7. The Cd content accumulated in the feces for C4 was the highest, and those for the groups other than C3 and C4 gradually decreased until 6 weeks and increased after that.
The results are as follows;
1. The rates of weight gain decreased in the order of C3>C2>C4>Cn>Cs>C1 groups. and C1 group to which only cadmium water had been fed was the lowest among them. The correlation between groups C1 and C3 was significantly different at the 1% level.
2. Food efficiency ratio(FER) decreased in the order of C3>C2>Cs>Cn>C4>C1. and the FERs of C3, C2, Cs, Cn and C4 are greater than that of C1 by 22.87, 19.89, 18.54, 14.20 and 13.17% respectively.
3. As for the Cassia tora L. powder-added groups, the amounts of cadimum accumulated in organs and tissues, that is, the brain, heart, spleen, liver, lungs, testicles, kindey, femoral muscale and leg bones were 0.45±0.04 to 0.83±0.04, 1.68±0.02 to 2.16±0.02, 3.26±0.05 to 4.62±0.27, 37.82±0.09 to 47.71±0.73, 1.07±0.10 to 1.66±0.04, 1.04±0.06 to 1.24±0.08, 36.79±0.20 to 39.61±0.53, 0.87±0.02 to 1.00±0.02 and 0.65±0.17 to 1.27±0.06 ㎍/g respectively.
4. The accumulated Cd content for C4 was the lowest among Cassia tora L. powder-added groups. When the results for C4 are compared with those for C1, it is observed that each cadmium content accumulated in the brain, heart, spleen, liver, lungs, testicles, kidney, femoral muscle and leg bones is dropped by 49.03, 22.56, 36.02, 35.75, 41.75, 36.20, 37.00, 22.77 and 56.67%, respectively, On the other hand, the accumulated Cd contest increased in the order of brain < leg bones < femoral muscle > testicles < lungs < heart < spleen < kidney < liver.
5. The average Cd accumulation rate in organs and tissues relative to the total Cd intake was 7.14% for C1, while they are 4.91, 4.81 and 4.50% for Cassia tora L. powder-added groups C2, C3 and C4, respectively.
6. The Cd content accumulated in the hair for C1 was the highest, and those for Cassia tora L. powder-added groups gradually increased until 6 weeks and decreased after that. 7. The Cd content accumulated in the feces for C4 was the highest, and those for the groups other than C3 and C4 gradually decreased until 6 weeks and increased after that.
