Objective : The aim of the study was to investigate the preventive effect of Acanthopanax senticosus(AS) aqua-acupuncture into Sinsu(BL23) of the multiple low-does strepozotocin(STZ)-induced diabetic rats.
Methods : The experimental animals were divided into 4 groups : normal group of rats, control group of multiple low-does STZ-induced diabetic rats, NSAA group with 0.4ml normal saline(NS) aqua-acupunctured subcutaneously into Sinsu in multiple low-does STZ-induced diabetic rats, and ASAA group with 0.4ml of 20% AS aqua-acupunctured subcutaneously into Sinsu in multiple low-does STZ-induced diabetic rats. Each of AS and NS aqua-acupuncture was done subcutaneously into both loci of Sinsu taking turns everyday for 3 weeks. Thereafter the levels of serum glucose, body weight, index of kidney hypertrophy, urine glucose, urinary albumin excretion, creatinine clearance, mesangial cell and TGF-β1 expression in glomeruli and tubular cells were measured on the determined day.
Conclusions :
1. Both ASAA and NSAA groups decreased the serum glucose levels in multiple low-dose STZ-induced diabetic rats as compared to the cintrol group, and ASAA group showed more significant decreases than NSAA group.
2. Both ASAA and NSAA groups prevented the development of diabetes in multiple low-dose STZ-induced diabetic rats as compared to the control group, and ASAA group prevented more markedly the development of diabetes than NSAA group.
3. Both ASAA and NSAA groups prevented the reduction of body weight in multiple low-dose STZ-induced diabetic rats as compared to the control group, and ASAA group showed the same as the normal group.
4. Both ASAA and NSAA groups did not show any changes of the creatinine clearance in multiple low-does STZ-induced diabetic rats.
5. Both ASAA and NSAA groups prevented the excretion of urinary glucose and albumin in multiple low-dose STZ-induced diabetic rats as compared to the cintrol group, and ASAA group showed more significant prevention than NSAA group.
6. Both ASAA and NSAA groups prevented the expansion of glomerular cells and the protein expression of transforming growth factor-β1 in multiple low-dose STZ-induced diabetic rats as compared to the cintrol group, and ASAA group prevented more significantly than NSAA group.
