Expression of Immunoglobulin M (IgM) and Immunoglobulin G (IgG) in Normal Wistar Rat Post-Cheral® Administration

Abstract

Maintaining immunoglobulin levels in the body is important to protect the body from exposure to pathogens. One effort can be made by consuming herbs containing immunomodulatory compounds, such as Cheral®, which includes a combination of herbs Phyllanthus niruri and Curcuma longa. This research aims to determine the expression of immunoglobulin M (IgM) and immunoglobulin G (IgG) following the administration of Cheral® to Wistar rats. The study was conducted in vivo, utilizing 24 healthy male Wistar rats for a 90-day treatment period. The research was divided into four treatment groups, including a control group and three dosage groups: Dose 1 (156.25 mg/kg BW), Dose 2 (312.5 mg/kg BW), and Dose 3 (468.75 mg/kg BW). IgM and IgG were isolated from the spleen and analyzed using flow cytometry. Flow cytometry data were analyzed using SPSS with a one-way ANOVA and post hoc test (p-value <0.05). The analysis showed that the relative number of IgM-producing cells in the control group was significantly higher than in the treatment groups, with a difference of 44.40%. In contrast, the relative number of IgG-producing cells in Dose 3 was significantly lower than all other treatment groups, showing a decrease of 29.21%. Overall, the expression of IgG and IgM did not differ substantially across all treatments. The lower IgG and IgM profiles compared to the control group indicate Cheral®'s ability to prevent infections and maintain the immune system of the rats throughout the treatment period.
