초록
The present study was intended to orally administer aronia to rats, irradiate radiation once to the whole bodies of the rats, and conduct blood tests to observe, compare, and analyze changes in blood cells, such as leukocytes, erythrocytes, and platelets, in order to examine the radioprotective effects of aronia. As experimental animals, 15 male Sprague-Dawley (SD) rats aged six weeks weighing 200∼250 g were taken and divided into the normal group (A) of five rats, the 5 Gy control group (B) of five rats, and the 5 Gy experimental group (C) of five rats. The normal group (A) was not ̃irradiated at all, the control group (B) was administered with general diets and irradiated, and the experimental group(C) was orally administered with 50 mg/kg/day of aronia two times per day to achieve a distilled water oral dose of 100 mg/kg/day and irradiated thereafter (5 Gy at 500 cGy/min) for 14 days. After the experiment, differences in leukocytes, erythrocytes, and platelets among the normal group (A), the control group (B), and the experimental group (C) were examined by comparing the counts of the blood cells and the results showed no statistically significant differences. However, on a detailed review, the normal group (A) showed statistically higher mean values for all of lymphocytes, hemoglobin, and mean corpuscular hemoglobin as compared to the control group (B) and the experimental group (C). Statistically significant differences in the counts of lymphocytes were shown between the normal group (A) and the control group (B), and between the normal group (A) and the experimental group (C); furthermore, statistically significant differences in mean corpuscular hemoglobin were shown between the normal group (A) and the experimental group (C). Given the results of the present study, in irradiated rats, aronia was generally considered as having no radioprotective effect on leukocyte, erythrocyte, and platelet while having statistically significant radioprotective effects on lymphocytes, hemoglobin, and mean corpuscular hemoglobin. Based on the present experiment, diverse studies should be conducted hereafter.
Abstract
The present study was intended to orally administer aronia to rats, irradiate radiation once to the whole bodies of the rats, and conduct blood tests to observe, compare, and analyze changes in blood cells, such as leukocytes, erythrocytes, and platelets, in order to examine the radioprotective effects of aronia. As experimental animals, 15 male Sprague-Dawley (SD) rats aged six weeks weighing 200∼250 g were taken and divided into the normal group (A) of five rats, the 5 Gy control group (B) of five rats, and the 5 Gy experimental group (C) of five rats. The normal group (A) was not ̃irradiated at all, the control group (B) was administered with general diets and irradiated, and the experimental group(C) was orally administered with 50 mg/kg/day of aronia two times per day to achieve a distilled water oral dose of 100 mg/kg/day and irradiated thereafter (5 Gy at 500 cGy/min) for 14 days. After the experiment, differences in leukocytes, erythrocytes, and platelets among the normal group (A), the control group (B), and the experimental group (C) were examined by comparing the counts of the blood cells and the results showed no statistically significant differences. However, on a detailed review, the normal group (A) showed statistically higher mean values for all of lymphocytes, hemoglobin, and mean corpuscular hemoglobin as compared to the control group (B) and the experimental group (C). Statistically significant differences in the counts of lymphocytes were shown between the normal group (A) and the control group (B), and between the normal group (A) and the experimental group (C); furthermore, statistically significant differences in mean corpuscular hemoglobin were shown between the normal group (A) and the experimental group (C). Given the results of the present study, in irradiated rats, aronia was generally considered as having no radioprotective effect on leukocyte, erythrocyte, and platelet while having statistically significant radioprotective effects on lymphocytes, hemoglobin, and mean corpuscular hemoglobin. Based on the present experiment, diverse studies should be conducted hereafter.
