In the present study, we compared differences in ionized calcium-binding adapter molecule 1 (Iba-1) and glial fibrillary acidic protein (GFAP) immunoreactivities for microglia and astrocytes, respectively, in the hippocampus of the seizure-resistant (SR) and seizure-sensitive (SS) gerbils.

Numerous embryoids formed from friable callus on MS with 5 mg/L of IAA, IBA or NAA developed only roots, but those formed on MS with 5 mg/L of BAP or KN developed shoots.
However, callus induced on MS with IAA (1 mg/L) or IBA (1 mg/L) on subculturing in the same medium with half-strength salts and sucrose (4%) produced both roots and shoots resulting in plantlets.
