  1. The anti-inflammatory potential (M2 polarization) of SZR104 was classified according to the changes it caused on selected cytomorphological features of cultured microglial cells [see refs.7,8,28,29,57,60]. Significant changes (p) are indicated as: *** (p < 0.005), ** (p < 0.05). N.S.: non-significant.
