Abstract

Histological staining usually requires deparaffinization before starting the staining process. Deparaffinization is a paraffin removal step that often uses a xylol solution. Deparaffinization with xylol has disadvantages, including being toxic, harmful to the human body, and hazardous to the environment. A safer alternative to xylol is required. Ylang-ylang oil, which contains β-caryophyllene, is non-polar and can be used as a substitute for xylol. This study aimed to compare the staining quality of guinea pig liver tissue slides with and without heating as a deparaffinization agent in hematoxylin-eosin (HE) staining. The research set up a quasi-experimental approach using samples of guinea pig liver tissue slides. The sample size was calculated using the Federer formula (n-1) (t-1) ≥ 15, resulting in a total sample of 27 slides divided into three treatment groups: xylol, ylang-ylang oil with and without heating. The Kruskal-Wallis test was used to examine the data. The quality staining of guinea pig liver slides deparaffinized with xylol was 100% good, and deparaffinization of ylang-ylang oil with heating was 100% good, whereas deparaffinization with ylang-ylang oil without heating was 11.1% less good, and the quality was good with an 88.9%. The normality test indicated that the data were not normally distributed (p0.05). The Kruskal-Wallis test was then used.

Abstract

The deparaffinization technique is critical in hematoxylin-eosin staining tissue slides. Xylol is an organic solvent that is frequently used as a deparaffinization agent, however, it has several hazardous effects. Alternative deparaffinization agents that are safer for the environment and humans are required, one of which is traditional mandar coconut oil (MTM). Lauric acid in MTM is non-polar, hence it can dissolve paraffin. The study aimed to evaluate the quality of staining results in mouse liver slide during the deparaffinization process using xylol and MTM with Hematoxylin-eosin (HE) staining. This study is an experimental design that uses 40 samples of mouse liver tissue slides, which were divided into two treatment groups. The Man-Whitney test was used to analyze data on the quality of tissue staining results based on nucleus, cytoplasm, and color homogeneity. The results of the staining quality of the mouse liver slide in the xylol and MTM groups obtained 100% good (score 3). The conclusion in this study is traditional mandar coconut oil (MTM) is effective for use as an alternative deparaffinization agent in HE staining.
