Abstract

The present study was carried out to summarize the effect of propolis in the diabetic rats by meta-analysis related studies. The association measure to test effect of propolis was Hedges's standardized mean difference between group of rats induced streptozotocin(STZ) or alloxan and group of rats induced STZ or alloxan treated with propolis about the considered 4 effect factors. In this particular fixed-effect model, blood glucose, Cholesterol, Triglyceride were significantly reduce. The case of heterogenous variable such as body weight, blood glucose, cholesterol, triglyceride, random-effect model was applied. In this model, blood glucose, triglyceride were decreased significantly in propolis treated group. According to the meta-regression analysis, period of injection was significant for body weight and blood glucose, cholesterol.

본 연구는 메타분석에서 헤지의 표준화된 평균차를 이용하여 당뇨에 걸린 쥐들에게 프로폴리스를 투여하여 체중, 혈당량, 콜레스테롤, 트리글리세리드의 평균비교를 통해 프로폴리스의 항-당뇨 효과에 대해 알아보았다. 고정효과모형을 적용시킨 결과 혈당량의 감소, 콜레스테롤 농도의 감소, 트리글리세리드 농도의 감소에 대해 유의한 효과를 보였고, 동질성 검정을 통해 동질성을 만족하지 않은 모든 변수에 대해 랜덤효과모형을 적용시킨 결과 혈당량의 감소와 트리글리세리드 농도의 감소에 대해 유의한 효과를 나타냈다. 또한 프로폴리스의 투여기간과 투여량에 대해 메타회귀분석을 실시한 결과, 투여기간이 체중, 혈당량, 콜레스테롤에 유의한 변수로 나타났다.
