Abstract

Background: This study aimed to evaluate and compare the histological effects of three commonly used fixatives (10% neutral buffered formalin, Bouin’s solution, and Carnoy’s solution) on mouse liver, heart, and testis tissues.Methods: A total of twelve healthy adult male mice were used, with four mice allocated to each fixative group. From each animal, the liver, heart, and testis were surgically excised and fixed in the designated solutions for standard durations. Tissues were processed using an automated tissue processor, embedded in paraffin, sectioned at 3 μm thickness, and stained with hematoxylin and eosin (H&E). Histological sections were then evaluated microscopically for nuclear clarity, cytoplasmic preservation, staining quality, and structural integrity.Results: The results demonstrated notable differences among the fixatives. Bouin’s solution provided superior nuclear detail in testicular tissue but was associated with mild tissue hardening. Formalin exhibited optimal preservation of overall morphology, particularly in liver and heart sections, with minimal artifacts. Carnoy’s fixative offered sharp nuclear contrast but was associated with noticeable tissue shrinkage and distortion.Conclusion: These findings highlight that the choice of fixative significantly affects histological outcomes, and selection should be guided by tissue type and diagnostic objectives. The study underscores the importance of appropriate fixation in enhancing tissue preservation and microscopic interpretation.
