Ethanol 투여가 체내의 Zn, Ca 및 Mg의 함량에 미치는 영향. = Effects of Ethanol on Zinc, Calcium, Copper and Magnesium Conoentrations of Tissues in Rats

국문 초록 (Abstract)

본 실험은 장기간의 알코올 섭취가 수종의 무기질 함랑에 미치는 영향을 알아보고자 랫트를 공시하여 4% 및 25% 알코올을 28일간 자유 섭취시킨 후 간, 신장, 근육 및 피모내의 Zn, Ca, Cu 및 Mg의 함량을 원자흡광분광광도법으로 측정하여 보았다.
실험결과를 요약하면 다음과 같다.
1. Zn 함량은 25% 투여군의 근육에서만 유의한(p<0.01) 감소를 나타내었으며 피모에 있어서는 4% 투여군에서 유의한(p<0.10) 증가를 나타내었다.
2. Ca 함량은 4% 및 25% 투여군의 간, 신장 및 근육에서 유의한 차이가 인정되지 않았으나 4% 투여군의 피모에서는 유의한(p<0.10) 증가를 나타내었다.
3. Cu 함량은 4% 및 25% 투여군의 근육에서만 유의한(p<0.05) 감소를 나타내었다.
4. Mg 함량은 4% 및 25% 투여군의 근육에서만 유의한(p<0.10, p<0.05) 감소를 나타내었다.

Present experiment was designed to investigate the effect of long-term ethanol drinking on the mineral contents on hair, liver, kidney and muscle tissues.
Forty-five rats were divided into 2 experimental groups and a control group. The control group received tap water and the other 2 groups 4% and 25% ethanol respectively as drinking source for 28 days. All rats were dissected on the 29th day. Hair, liver, kidney and muscle samples were taken and analyzed for zinc, calcium, copper and magnesium contents by atomic absorption spectrophotometeric method.
The results obtained are summarized as follows:
1) The zinc content of muscle in 25% ethanol group showed significant (p<0.01) decrease whereas that of hair in 4% ethanol group showed significant (p<0.1) increase.
2) The calcium content of hair in 4% ethanol group showed significant (p<0.1) increase whereas that of hair, kidney and muscle in both group showed no significant difference.
3) The copper and magnesium contents of muscle showed significant (p<0.1, P<0.05) decrease in both groups.
From these results it may be concluded that the long-term drinking of ethanol affects the mineral content of body tissue.
