Here we present a protocol to describe the localization of angiotensin II Type 1 receptors in the rat brain by quantitative, densitometric, in vitro receptor autoradiography using an iodine-125 labeled analog of angiotensin II.

Microhardness is a mechanical property and an informative parameter for evaluating hard tissue pathophysiology. Here, we demonstrate a standardized protocol (sample preparation, polishing, flat surface, and indentation sites) for microhardness analysis in tooth and alveolar bone in rodent oral disease models, namely, dental fluorosis, and ligature-induced periodontal bone resorption.
