알루미늄 화합물이 흰쥐의 혈청 효소 활성도에 미치는 영향

Effects of Aluminum Compounds on Enzyme Activities in the Serum of Rat

알루미늄 화합물이 흰쥐의 효소활성에 미치는 영향을 알아보고자 흰쥐(Sprague-Dawley계 male) 75마리를 5개 그룹 즉, 대조군, $250\;ppm\;AlCl_3\;500\;ppm\;AlCl_3,\;250\;ppm\;Al_2(SO_4)_3,\;500\;ppm\;Al_2(SO_4)_3$로 나누어 2주동안 투여하여 asparate amino transaminase, alanine amino transminase, lactate dehydrogenase, 그리고 cholinesterase의 변화를 조사하였다. 체중은 대조군에 비하여 $Al_2(SO_4)_3$ 투여군은 2.82-6.16% 증가한 반면에 $AlCl_3$ 투여군에서는 0.53-3.35%로 감소하였다. 효소활성은 대조군에 비하여 $AlCl_3$ 또는 $Al_2(SO_4)_3$ 투여후에 AST는 0.68-9.97%, 21.04-24.79%, LDH는 29.43-57.56%, 74.60-29.33% 증가하였으나, ALT는 12.69-25.42%, 24.32-39.62%로 각각 감소하였다. ChE는 대조군에 비하여 $Al_{2}(SO_4)_3$ 투여군은 28.0-12.73% 증가하였으나 $Al_2(SO_4)_3$ 투여군은 3.93-14.48% 감소하였다.

This study was performed to investigate the effect of serum enzyme activities in rats after administration of aluminum compound. Seventy five male Sprague-Dawley rats were divided into five groups consisting of control, $250\;ppm\;AlCl_3,\;500\;ppm\;AlCl_3,\;250\;ppm\;Al_2(SO_4)_3$ and $500ppm Al_2(SO_4)_3$ groups and kept on the diet for 2 weeks. The weight gain increased from 0.53 to 3.35% in $AlCl_3$ adiministration groups but decreased from 2.82 to 6.16% in $Al_2(SO_4)_3$, administration groups as compared to control group. As compared to control group, activities of lactate dehydrogenase (LDH) and aspartate amino transaminase (AST) in serum increased 29.43 to 57.68% and 0.68 to 9.97% in $AlCl_3$ adiministration groups, and 74.60 to 29.33% and 21.04 to 24.79% in $Al_2(SO_4)_3$ adiministration groups, respectively. However, alanine amino transminase (ALT) decreased from 12.69 to 25.42% in $AlCl_3$ adiministration groups and from 24.32 to 39.62% in $Al_2(SO_4)_3$ administration groups. Cholinesterase activity increased from 28.98 to 12.73% as compared to control group by administration of $AlCl_3$ and decreased from 3.93 to 14.48% by administration of $Al_2(SO_4)_3$.
