Abstract

We examined effects of red ginseng on the formation of glycated protein in vivo and in vitro. The mixtures (1 : 1 : 1, v/v/v) with glucose (1.5 g/dl, hemoglobin (10 g/d) and red ginseng extract (0.5 g/dl) in 0.067 M phosphate saline buffer were incubated for 5 days in shaking water bath (37$\^{C}$, 70 RPM). Male rats were divided into three groups with one health and two diabetes, consisting of 20 heads in each group. Diabetic rats, induced by streptozotocin injection, were treated with or without red ginseng extract (100 mg/kg/day) for 3 months. The concentration of blood glucose and the rate of glycated hemoglobin were determined by commercial kits. The rate of glycated hemoglobin was significantly decreased by the addition of ginseng extract in comparison with non-addition group in vitro (12.17$\pm$ 1.01% vs 15.9$\pm$ 1.95%, meansd, p<0.01). Even though the levels of blood glucose in rats were not significantly different from each other, the rate of glycated hemoglobin in ginseng treated diabetic rats was $\pm$ se significantly lower than non-treated diabetic rats after 3 months (15.1$\pm$ 2.06% vs 20.1 $\pm$ 2.9%, mean$\pm$ sd, p<0.05). Additionally, the body weight was increased, drinking water volume was decreased non-significantly by the treatment of ginseng extract. These results suggest that ginseng can also inhibit the formation of glycated protein by other mechanisms which are not related with hyoglyemic effect of ginseng.

당화헤모글로빈의 형성을 포함한 당뇨병에 대한 인삼의 보호작용에 대하여 조사하고자 인산완충용액으로 포도당(1.5 g/dl), 헤모글로빈(10 g/dl) 및 홍삼액기스(0.5 g/dl)의 혼합용액(1 : 1 : 1, v/v/v)을 생산하여 시험관에 옮긴 후 37$^{\circ}C$에서 5일간 배양하였다. 또한 웅성 백서를 각 군당 20두씩 할당하여 건강한 군과 streptozotocin으로 유발된 당뇨군으로 나누고 이를 다시 인삼투여군과 그 대조군으로 나누어 홍삼액기스를 음용수에 용해하여 100 mg/kg/day의 용량을 3개월 동안 투여하였다. 혈당의 농도와 당화헤모글로빈의 비율은 시판되는 키트를 사용하여 측정하였다. 홍삼액기스를 첨가한 시험관의 당화헤모글로빈이 첨가하지않는 대조군에 비하여 유의하게 감소되었으며(12.17$\pm$1.01% : 15.9$\pm$ 1.95%, p<0.01) 홍삼액기스를 투여한 당뇨쥐의 혈당은 그 대조군에 비하여 유의한 차이가 없음에도 불구하고 3개월 후의 당화헤모글로빈의 비율이 유의하게 감소되었다(15.1$\pm$2.06% : 20.1$\pm$2.9%, p<0.05). 또한 3개월 후 홍삼액기스를 투여한 당뇨쥐는 그 대조군에 비하여 체중이 증가 되었으며 음수량이 감소 되었다. 이런 결과들로 보아 인삼은 당화단백질의 형성을 저혈당 작용이 아닌 다른 방법으로도 억제할 수 있을 것으로 생각한다.
