Abstract

Objective: The incidence of small intestine cancer (SIC) is rising despite available preventive measures. Kaempferol and quercetin are a potential chemopreventive agent for SIC, but in vivo findings are inconclusive. We aim to study the effects of kaempferol and quercetin on colitis-associated small intestine carcinogenesis in mice. Methods: Suppression effect was tested using mice divided into 6 groups of treatment, i.e.; normal (N) group, negative control (NC), leaf extract (medium dose [MD]) dose 12.5 and 25 mg/kg body weight (BW), leaf extract chitosan and nanoparticle of mahkota dewa (NPMD) dose 6.25 and 12.5 mg/kg BW. Dextran sulfate sodium induction of 1% w/v was administered through drinking water for 6 weeks of treatment. The suppression effect was observed histopathologically by counting the mitotic cells and hyperplasia cells of the crypt of small intestine with hematoxylin-eosin staining. Results: Mitosis cells mean of NC group was not significant difference either with MD 12.5 (p=0.394) or MD 6.5 (p=0.310). However, mitosis cell mean appears to be lower in the NPMD 12.5 (p=0.09) and NPMD 6.25 (p=0.05) groups than the NC group. There was a significant difference among the mean of hyperplasia NC group and MD and also NPMD group. Significant difference also can be showed between MD 12.5 and MD 25 (p=0.026), and between NPMD 6.25 and NPMD 12.5 (p=0.002), and between MD 12.5 and NPMD 12.5 (p=0.002). Conclusion: Our results demonstrate suppression of hyperplasia small intestine by either nanoparticle or extract of Phaleria macrocarpa extracts. The suppression of mitosis was showed by administration of nanoparticle.
