Abstract
Objectives : This study was performed to investigate immune regulatory effects of the pharmacopuncture with MOK on hyperthyroid rats. Methods : The experimental hyperthyroidism was prepared by the intraperitoneal injection of L-thyroxin (LT4, 0.5 mg/kg) once daily for 2 weeks in Sprague-Dawley(SD) rats. The pharmacopuncture with MOK extrac (MOK pharmacopuncture) at doses of 0.3 or 3 mg/kg was injected on acupuncture points in the thyroid glands of hyperthyroid rats once a day for 2 weeks. Propylthiouracil(PTU, 10 mg/kg) as a reference group was subcutaneously injected into the dorsal neck. We measured the levels of IFN-γ and IL-4 in the sera of rats using enzyme-linked immunosorbant assay(ELISA) and determined the expression of IFN-γ, IL-4, IL-10, and Foxp3 in spleen tissues by reverse transcriptase-polymerase chain reaction(RT-PCR). Results : The treatment of MOK pharmacopuncture in hyperthyroid rats significantly decreased the serum levels of Th1 cytokine, IFN-γ(p<0.01 for MOK 0.3 mg/kg, p<0.05 for MOK 3 mg/kg, and p<0.05 for PTU) and significantly increased the levels of Th2 cytokine, IL-4(p<0.05 for MOK 0.3 mg/kg, p<0.001 for MOK 3 mg/kg, and p<0.05 for PTU) compared to control group. Also, the MOK pharmacopuncture significantly increased IL-4 expression(p<0.05 for MOK 3 mg/kg, and p<0.05 for PTU), IL-10(p<0.05 for MOK 3 mg/kg, and p<0.01 for PTU), and Foxp3(p<0.01 for MOK 0.3 mg/kg, p<0.05 for MOK 3 mg/kg and p<0.01 for PTU) in spleen tissues of hyperthyroid rats compared to control group. Conclusions : Our results suggest that MOK pharmacopuncture can help to ameliorate the pathological progression of hyperthyroidism by regulation of the Th1/Th2 imbalance.
