This study was performed to investigate the influence of Chlorella which effected the change of Pb contents, enzyme activity and lipid compounds on the rats fed the beverage involved Pb and the different contented Chlorella added-diets for 18weeks. The rat's weight of 200ppm Pb group was decreased 6.04% and the cause of that was Pb intake. But the rat's weight of Chlorella added-diets+200ppm Pb group was increased 4.02%(p<0.01). When feeding the different(0%, 2%, 5%, 10%) Chlorella added-diets with the Pb contented beverage to the rats, we could know that the Pb contents accumulated on tissue were decreased to 20.70(0%), 12.88(2%), 14.83 (5%) and 19.56(10%), compared with the quantity of Pb taken in. Total-cholesterol, triglyceride, glucose content and AST, ALT, ALP, LDH enzyme activity in serum were the highest on 200ppm Pb group and those were decreased by the order of different (2%∼5%>10%) Chlorella contents +200ppmPb group. A significance was recognized on the level of 1%. Therefore, when rats were exposed to Pb, it was thought that the amount of Chlorella intake was adequate on content 2∼5% for reducing the lead toxicity.

Biogenic amines can be formed and degraded either as the result of endogenous amino acid decarboxylase activity in raw materials or by the growth of decarboxylase-positive microorgannisms under conditions favorable to enzyme activity. Three biogenic amines(Tryptamine, Histamine, Tyramine) were intensively investigated by the HPLC during Kimchi fermentation at 5℃. The patterns of microfloral changes in lactic acid bacterial group, Leuconostoc, Streptococcus and Lactobacillus, were similar to the typical low-temperature fermentation. The population of microbial growth were high after 10 days and gradually decreased. The levels of Tyramine were lowered(10mg/kg) during this mid-periods(8∼16 days) but very high in initial-(15mg/kg) and final-periods (30mg/kg), in which the total acidity ranged between 0.2∼0.35% and 0.4∼0.6%, while the acidity in mid-periods revealed 0.35∼0.4% beginning the initial ripening period. Leuconostoc was highly increased in number in mid-period but slightly declined as the acidity increased, whereas Streptococcus was highly distributed in initial-period and Lactobacillus in final-period. The levels of Tryptamine and Histamine were relatively low throughout the whole fermentation period, but the profile of Tryptamine level was very similar to the case of Tyramine. Histamine was maintained at a certain level after mid-period of fermentation.

In order to observe the Na contents, Korean common foods, especially processed foods were analyzed by Atomic Absorption Spectrophotometer. 1. The Na contents of instant noodle (ramen) was 400-900 mg/100 g and Na contents of their soup powder was 10000-16000 mg/100 g. 2. The Na contents of corns snd beans was very low but their processed foods, corn flake and soybean milk, had relatively high Ns contents. 3. The Na contents of meats was 40-60 mg/100 g but the Na contents of meats products was 700-900 mg/ 100 g. 4. The Na contents of flavoring salt was 12000-38000 mg/100 g, those of soybean products was 3000-6000 mg/100 g, and that of seasoning MSG was 8000-17000 mg/100 g. 5. There was no statistical difference between the results of wet ash method and dry ash method in the Na contents of all food groups.

The purpose of this study is to investigate the effect of raw Cassia tora L. powder added-diets on reducing cadmium accumulation in rats. The experimental animals were Sprague-Dawley family(♂ , 4 weeks) which was classified into normal group CN, 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 fix the Cassia tora L. powder-added groups, the amounts of cadmium accumulated in organs and tissues that is, the brain, heart, spleen, liver, lungs, testicles, kidney, femoral muscle and leg bones were 0.45±0.04 to 0.83±.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 content 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 4.509a 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.
