Abstract

Microscopic examination of cancer development can be identified through histopathological examination. Hematoxylin–eosin (HE) is the gold standard for staining method. This processing can be obstructed if hematoxylin reagent out of stock in the laboratory. Other reagents are needed that can replace the use of hematoxylin, one of which is crystal violet. This study aims to evaluate the use of crystal violet as a nuclei stain in breast cancer preparations. The research sample consisted of 15 breast cancer preparations taken at the sample bank in the anatomical pathology laboratory of RSUD Dr. Slamet Garut. The results showed that from 15 preparations, it was observed that 4 preparations (27%) stained worth and 11 preparations (73%) stained poorly. Based on the research results, crystal violet crystal violet has a low core coloring ability in breast cancer preparations. From the results of this study, it is recommended to modify the crystal violet reagent by paying attention to the acidity of pH and concentration of crystal violet.

Abstract

Tissue staining using hematoxylin-eosin (HE) is a standard method of histopathological staining. The tissue staining is hampered when there is no hematoxylin reagent in laboratory. Therefore, other reagents are needed that can replace the use of hematoxylin. Methylene blue is a basic dyes that interact with cell nuclei which has a negative ionic charge of the tissue. It can be used as an alternative nuclei staining. This study aims to evaluate the use of 1% of methylene blue in cell nuclei staining in histopathological preparations. The research sample were 15 pathology preparations which were randomly selected including breast cancer, cervical cancer and ovarian cancer in the bank of sampel at anatomical pathology laboratory of RSUD Dr. Slamet Garut, Indonesia. The experiment showed that the methylene blue dyes yielded “worth” result (40%) and “poorly” result (60%). Further research can be carried out by modifying the pH of 1% of methylene blue reagent so that it can maximize the staining preparations results as good as those using hematoxylin.
