Representative photomicrographs of cerebral cortex (A) and hippocampal CA1 region (B) of rat brain sections.
<p>Sections were stained with Haematoxylin and Eosin. Black arrows indicate neuroinflammation along with apoptotic cells 1: sham control: neurons are intact 2: OBX control: mild-moderate infiltration of inflammatory cells with large number of apoptotic cells 3: treated with curcumin (200 mg/kg): slight inflammation of neurons with less apoptotic cells 4: treated with curcumin (200 mg/kg) +piperine (20 mg/kg): neurons are preserved.
