Objective: Excessive TNF-a production in colon mucosa is known to cause homeostasis disturbance, which then
lead to chronic inflammation reaction. Inflammatory Bowel Diseases (IBD) is a clinical condition caused by the
chronic inflammation reaction. The diseases incidence is high globally. TNF-a expression is known to have a key
role that connects chronic inflammation and the risk of malignancy. To date, effective drug that maintain IBD
remission with mild adverse effect has yet to be found. This study aims to determine whether encapsulation of
mahkota dewa leaf extract in chitosan nanoparticles can suppress TNF-a expression.
Methods: This study involves 30 samples colon tissue mice from previous study that has been stained using
immunohistochemistry (IHC). Included mice were divided into 6 intervention groups: a group without intervention
(N); a negative control group which were only given DSS 2% b/v; two groups which were given DSS 2% b/v
followed by mahkota dewa leaves extract administration, with dosages of 25 and 12.5 mg, respectively; and two
groups which were given DSS 2% b/v followed by chitosan nanoparticle-encapsulated mahkota dewa leaves extract
with dosages of 12.5 and 6.25 mg in their drinking water.
Results: TNF-a expression index of groups treated with NPMD 12.5 mg and NPMD 6.25 mg shows significant
reduction (p<0.05), while the reduction in groups treated with EMD 25 mg and EMD 12.5 mg is not significant
(p>0.05), both compared to control group.
Conclusion: Low dose mahkota dewa extract loaded in chitosan nanoparticles is able to suppress TNF-a
expression in mice colon tissue.
