To explore the influence of Astragalus membranaceus (AM) on serum cytokines, Th1, including interleukin-2 (IL-2) and gamma-interferon (gamma-IFN), and Th2, including interleukin-4 (IL-4) and interleukin-10 (IL-10), in patients with herpes simplex keratitis (HSK).


One hundred and six HSK patients were randomly divided into the AM treated group and the ribavirin treated group. Levels of serum IL-2, IL-4, IL-10 and gamma-IFN of all the patients and 62 healthy person, selected from donors for control group, were determined by sandwich enzyme-linked immunosorbent assay (ELISA) technique.


Levels of serum IL-4 and IL-10 in HSK patients were significantly higher and those of IL-2 and gamma-IFN were significantly lower than those in the healthy control (all P < 0.01). These parameters were significantly improved in the patients of the AM group after treatment, but with no change in patients of the ribavirin group.


AM can modulate the imbalance state of Th1/Th2 in HSK patients, improve their immune function disturbance, that shows important significance in treating HSK.
