Abstract
Aim: This is an experimental study aimed at exploring the capability of Hibiscus extract-iron solution counterstained with van Gieson stain to demonstrate collagen fibres in skin tissue.
Methods: 10% neutral buffered formalin fixed, paraffin embedded tissue blocks of skin were retrieved from the tissue block archive of the Department of Pathology, Unilorin Teaching Hospital, Ilorin, Kwara State, Nigeria. Two blocks were randomly selected and sectioned serially at 4 microns. The sections were primarily stained progressively with locally sourced and compounded Hibiscus sabdariffa extract-iron- solution. They were subsequently counterstained with van Gieson. Parallel sections were stained with HVG and H&E as controls.
Result: Photomicrographs reveal satisfactory staining of collagen fibers comparable to routinely used HVG.
Conclusion: This study established the capability of Hibiscus-van Gieson to demonstrate collagen fibres and could be useful in dermato-histoarchitectural studies.
