Figure 4From: Tat-induced histopathological alterations mediate hippocampus-associated behavioural impairments in rats Photomicrograph of haematoxylin and eosin stained Saline and Tat sections. Photomicrograph of haematoxylin and eosin stained Saline and Tat sections (A) hippocampal formation and dentate gyrus of a Tat-injected brain (200×). White arrow represents the path of the tract created by the needle and the ‘x’ indicates the site of injection, Scale bar = 200 μm; (B) the pyramidal cell layer (PC) in a Saline-injected rat brain Post-injection (100×), Scale bar = 100 μm; (C) the pyramidal cell layer (PC) in a Tat-injected brain Post-injection (100×), Scale bar = 100 μm; (D) Neurons and glial cells in the Saline-injected brain (50×); White arrows represent normal astrocytes, Scale bar = 50 μm; (E) Neurons and glial cells in the Tat-injected brain (50×). Yellow arrows show astrocytes undergoing gliosis, Scale bar = 50 μm.Back to article page
