초록

본 연구는 TCDD로 급성독성을 유도한 자정 기니픽의 대퇴골 무게감소에 대한 홍삼사포닌의 효과를 조사하기 위해 수행하였다. 48 마리의 자성기니픽 ($820{\pm}25\;g$)을 6 군으로 나누어 정상군 (NC), TCDD 단독투여군 (TT), 사포닌 전투여 군 (PE10, 20), 사포닌후투여군 (CE10, 20)으로 나누었다. NC군은 vehicle과 saline 만을 투여하였고, TT군은 TCDD를 단회투여 ($5.0\;{\mu}g$, i.p) 하였다. PE10 및 20군은 TCDD 투여 1 주일 전부터 총 3 주동안 사포닌을 투여 (복강) 하였다. 반면 CE10 및 20군은 TCDD 투여한 직후부터 총 3 주동안 사포닌을 투여 (복강) 하였다. 사포닌 투여군의 체중변화를 살펴보면 TT군은 TCDD 투여후 유의적인 체중감소 현상이 관찰되었으나 PE10, 20 및 CE10, 20 등 사포닌 투여군에서는 TT군에 비해 체중이 모두 증가하는 경향을 보였다 . TCDD 투여는 지정기니픽의 대퇴골 무게를 유의적으로 감소시키는 반면 홍삼사포닌의 투여는 대퇴골 무게감소를 억제하는 경향을 보였다. 대퇴골 무게감소 억제현상은 PE20군에서 가장 높게 나타났다. 대퇴골의 $Ca^{2+}$도 TT군은 NC군 대비 약 20.4% 감소하는데 반해 사포닌 투여군은 TT군 대비 $Ca^{2+}$ 함량이 증가되는 경향을 나타내었다. 이러한 결과로부터 홍삼사포닌은 TCDD에 의해 억제된 기니픽의 대퇴골 내 $Ca^{2+}$ 함량을 증가시킴으로써 대퇴골의 무게감소를 회복시키는 것으로 추론할 수 있겠다.

To investigate the protective effect of saponin from red ginseng extract, 2,3,7,8-tetrachlorodibenzo--dioxin (TCDD) was exposed to female guinea pigs and then femur weights was measured. Forty eight female guinea pigs ($820{\pm}25\;g$) were divided into 6 groups. Normal control group (NC) received vehicle and saline; only TCDD-treated group (TT) received TCDD ($5.0\;{\mu}g/kg$, single dose) intraperitoneally; pretreated group of saponin 10 (PE 10) received 10 mg/kg of saponin i.p. for 4 weeks from 1 week before TCDD-exposure; pretreated group of saponin 20 (PE 20) also received 20 mg/kg of saponin i.p. for 4 weeks from 1 week before TCDD-exposure. While, post-treated group of saponin 10 (CE 10) received 10 mg/kg of saponin i.p for 3 weeks after TCDD-exposure. Post-treated group of saponin 20 (CE 20) received 20 mg/kg saponin i.p for 3 weeks after TCDD-exposure. Body weight of TT group was significantly decreased after TCDD-exposure. However, body weight in all saponin-treated groups increased throughout the experimental period, although the increasing rate was slower than that of NC group. Body weights of PE 10 and 20 groups showed more higher increase than those of CE groups during the experimental period. Decrease of femur weights in female guinea pigs by TCDD intoxification was significantly recovered by the saponin treatment. Decrease of $Ca^{2+}$ level of femurs in female guinea pigs exposed TCDD also recovered by the treatment of saponin from red ginseng extract. Especially, PE20 group showed the highest increase of the $Ca^{2+}$ level in femur among the saponin treated groups. These results suggest that ginseng saponin might be a useful protective agent against femur damage caused to decrease of $Ca^{2+}$ by TCDD.
