Histological comparison of basilar arteries in sah group with and without diazepam treatment. The image illustrates endothelial cell damage, inflammatory infiltration, and structural disruption in the SAH group (right), while the Diazepam-treated SAH group (left) shows a reduction in vasospasm and inflammation. Wall thickness and lumen diameter suggest a protective effect of diazepam against SAH-induced vascular pathology. (Note: Hematoxylin & Eosin staining; magnification, 50x).
