Abstract

This study has been carried out to understand the effect of SP3 and GV6 acupuncture on the hyperglycemic rat induced with Streptozotocin (STZ). Diabetes was induced in experimental groups by inraperitoneal injection of STZ (50mg/kg of body weight) twice by 24 h interval and the additional 100mg/kg 3 days after the earlier treatment. Control group was treated with tail-non acupoint, and experimental groups were treated SP3, GV6 and SP3+GV6 after hyperglycemic induction for 6 weeks. The body weight of control was lower than the experimental groups. The blood glucose was decreased significantly in the experimental groups. Glucose tolerance in acupuncture treated groups was improved. Blood cholesterol level and transaminase activites were lower in the experimental groups than in the control. In the SP3 or GV6 treated rats, hepatocyte degeneration were apparently decreased and the organelles were properly arranged. Furthermore, decrease in liver IGF-I mRNA expression was improved by the acupuncture in STZ-induced diabetic rats. In conclusion, our observation indicate that SP3 or GV6 acupoints treatment can exert beneficial effects in diabetes, with preservation of ${\beta}-cell$ function and liver function.

STZ 유발 당뇨병 흰쥐에 척중혈(GV6)과 태백혈(SP3)에 대해 침 시술을 하여 체중, 혈당량변화, 당내성변화, 혈액내 지질함량, transaminase활성도 측정, 간조직의 조직학적 관찰, 간조직에서 IGF-I mRNA유전자 발현변화 및 간세포의 미세구조변화를 관찰한 결과 다음과 같은 결론을 얻었다. 실험군에서는 대조군에 비하여 체중감소 억제 및 혈당 강하의 효과가 있었고, 간의 조직학적 관찰 결과 STZ로 인하여 손상된 간장 조직이 상당부분 회복되었는데 이로써 척중혈(GV6)과 태백혈(SP3)에 대한 자침이 당뇨로 인한 간장조직의 회복에 임상적으로 유의한 효과를 나타낼 것으로 사료된다. 그러나 실험 결과 중 체간부 경혈인 척중혈 (GV6)과 사지부 경혈인 태백혈 (SP3)의 효과는 각각 차이가 있었는데, 체중감소 억제, 혈당량의 감소, 당내성 검사에서 혈당량의 감소, 혈청 HDL-cholesterol의 감소, 간효소치의 감소등에서는 척중혈(GV6)을 단독 시술하는 것이 가장 유효하였다. 척중혈 (GV6)과 태백혈 (SP3)의 병용 시술의 효과는 전체적으로 단독시술에 비해 떨어지거나 비슷하였으며, 간조직에서 IGF-I mRNA발현양상은 병용시술이 당뇨에 의해 감소된 IGF-I 유전자 발현의 증가를 유도하였다. 이상의 결과에서 STZ유발 당뇨병 흰쥐에서 척중혈(GV6)과 태백혈(SP3)의 침 시술이 당뇨병의 제증상을 유의하게 개선시키는 것으로 나타났으며 척중혈(GV6)에 대한 시술이 태백혈(SP3)또는 척중혈 (GV6)과 태백혈(SP3)을 동시에 시술하는 것보다 유의한 효과가 있는 것으로 나타나 앞으로 임상에서 당뇨병 치료에 사용될 수 있을 것으로 생각된다.
