Radiation Protection Effect of Blueberries in the Hematopoietic Cells of White Rats

The purpose of this study was to investigate the radiation protection effect of blueberries. The experimental animals used in this study were 8-week-old 21 SD male rats weighed 280-300 g. The animals were set to a normal group (A), a 5 Gy control group (B), and a 5 Gy experimental group (C) of seven rats each, and (50 mg/kg/day) of physiological saline solution of blueberries were orally administered twice a day with an oral dose of (200 mg/kg/day) for seven days and 5 Gy of radiation was irradiated in the case of groups B and C. As a result, it was identified that there was significance in white blood cells in this study (p<0.000). There was no significant difference in red blood cells or platelets. When examined in detail, among white blood cells (WBC), neutrocytes were found to be significantly different among the three groups: normal, control, and experimental groups (p<0.004). Lymphocytes were also found to be statistically significantly different among the three groups (p<0.000). Monocytes were not found to be statistically significantly different (p<0.483). When red blood cells (RBC) were examined, hemoglobin (HGB) was not found to be statistically significant different among the three groups (p<0.291). Hematocrit (HCT) was not found to be statistically significantly different among the three groups, either (p<0.564). Mean corpuscular volume (MCV) was found to be statistically significantly different among the three groups (p<0.001). Mean corpuscular hemoglobin (MCH) was also found to be statistically significantly among the three groups (p<0.028). Mean corpuscular hemoglobin concentration (MCHC) was found to be statistically significantly different among the three groups(p<0.020). Red blood cell distribution width (RDW) was not found to be statistically significantly different among the three groups (p<0.09). When platelets (PLT) were examined in detail, mean platelet volume (MpV) was found to be statistically significantly different among the three groups (MpV) (p<0.04). In conclusion, based on this study, blueberries are considered to have radiation protection effects.

흰쥐의 조혈세포에서 블루베리의 방사선 방호효과

본 연구는 블루베리의 방사선 방호효과를 알아보고자 하였다. 실험동물은 SD계 Rat 8주령 280~300 g 수컷 21마리를 사용하여 7마리를 하나의 군으로 정상군(A), 5 Gy 대조군(B), 5 Gy 실험군(C)으로 설정하였고, 생리식염수 경구투여량(200 mg/kg/day)로 1일 2회씩 50 mg/kg/day로 흰쥐에 7일 동안 경구투여 한 후 방사선 조사는 5 Gy를 조사 하였다. 그 결과 본 연구에서는 백혈구에서 유의성이 있음을 확인할 수 있었다(p<0.000). 적혈구나, 혈소판에서는 유의한 차이를 보이지 않았다. 세부적으로 살펴보았을 때 백혈구(WBC)는 호중구에서 정상군, 대조군, 실험군, 세 집단간 유의성이 있었다(p<0.004). 림프구에서도 통계적으로 세 집단간 유의성이 있었다(p<0.000). 단핵구에서는 통계적으로 유의성이 없었다(p<0.483). 적혈구(RBC)를 살펴보면, 혈색소(HGB)는 통계적으로 세 집단간 유의성은 없었다(p<0.291). 적혈구용적백분율(HCT)에서도 세 집단간 통계적으로 유의성은 없었다(p<0.564). 평균적혈구용적(MCV)에서는 통계적으로 세 집단간에 유의한 차이를 보였다(p<0.001). 평균적혈구혈색소양(MCH)에서 통계적으로 세 집단간 유의한 차이가 있었다(p<0.028). 평균적혈구혈색소농도(MCHC)에서 세 집단간 통계적으로 유의한 차이가 있었다(p<0.020). 적혈구분포폭(RDW)은 유의성이 없었다(p<0.09). 혈소판(PLT)에서 세부적으로 살펴보면, 평균혈소판용적(MpV)에서 통계적으로 세 집단간 유의성이 있었다.(p<0.04). 결론적으로 본 연구를 통하여 블루베리가 방사선 방호효과가 있는 것으로 사료된다.
