It was aimed to evaluate the regressive effect of grayanotoxin-rich Turkish mad honey and 5-fluorouracil (5-FU), separately and together by using the Nmethyl- N-nitrosourea (MNU)-induced colon cancer modelling in rats. Study groups were designed as control group (CG), cancer control group (CCG), 5- Flourouracil group (FUG), Turkish mad honey group (HG), Turkish mad honey and 5-FU combined group (FU-HG). White blood cell (WBC), lymphocyte, eosinophil, basophil, serum lactate dehydrogenase (LDH), total oxidant status (TOS), and total protein values of the rats in the CCG were significantly lower than the values of the rats in the CG, whereas serum Bcl-2 and survivin levels were significantly higher in the rates belonged to the CCG in comparison to those in the CG. The presence of anaplastic epithelial cells, vascularization, precancerous changes, and inflammatory infiltration detected in the colon and small intestine of the rats in FU-HG, FUG, HG were less intense (P<0.05) compared to the findings in the rats in CCG. In conclusion, mad honey and 5- FU reduced anaplastic cell growth and oxidative stress via suppressed antiapoptotic activity. Considering the histopathological findings in the liver and kidney, no toxicity occurred related to mad honey and 5-FU metabolization. Therefore, the combined use of these two substances may be an alternative method in the treatment of colon cancer. [ABSTRACT FROM AUTHOR] |
