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

Deparaffinization is a stage before the staining process to remove/dissolve paraffin so that the absorption of color in tissue preparations is maximized. Deparaffinization is usually carried out using xylol and toluol. Xylol has toxic effects including acute neurotoxicity, heart and kidney damage, hepatotoxicity, fatal blood dyscrasias, skin erythema, dry skin, peeling skin, and also has a carcinogenic effect. The toxicity effect of olive oil is lower than that of xylol. Oils that have non-polar properties can remove the remaining paraffin contained in the tissue. The purpose of this study was to determine the microscopic appearance of the kidney tissue preparations of mice deparaffinized with olive oil on hematoxylin eosin (HE) staining. The type of research used is experimental research which is analyzed with a descriptive approach. The results of the assessment of preparations deparaffinized with xylol in 80 visual fields obtained 100% good preparations and preparations deparaffinized with olive oil in 80 visual fields obtained 0% poor preparations, 11.3% poor preparations, and 88.7% good preparation. So it can be said that better results are found in the microscopic picture of the kidney preparations of mice (Mus musculus) deparaffinized with xylol.

Abstract

Clearing results in histological processing can be affected due to tissue density and viscosity of the clearing agent. Xylene is the most commonly used aromatic solvent for clearing agents and deparaffinizing agents in histopathology laboratories, but xylene is one of the most dangerous chemicals found in histology laboratories. Based on the dangers posed by xylene, a replacement material is needed. Several xylene substitutes such as reagents derived from limonene, aliphatic hydrocarbons, vegetable oils and mineral oils have been commercially developed, but the available xylene substitutes are still less effective, more expensive, and still as dangerous as xylene itself. Substitutes that are considered safer are from natural oils, one of which is olive oil which has similarities with xylene, namely in hydrocarbon and phenol compounds. This study used two types of tissue, namely skin and liver from mice (Mus musculus) which were cut into two parts; the first part uses xylene as and the other part uses olive oil as a clearing agent. The assessment of hematoxylin eosin staining results were determined based on the category of assessment of cell structure, such as the cell nucleus, cytoplasm, and color uniformity carried out by three readers and five fields of view for each microscopic slide at 40X magnification of the objective lens. Comparison of observations of the xylene group in skin and liver tissue 100% got a good score on the cell nucleus, cytoplasm, and color uniformity. (p=1,000). The olive oil group had a slight difference in color uniformity in liver tissue when compared to skin, but not statistically different (p=0.773). The comparison of the overall readings of the xylene and olive oil groups on skin and liver tissue also showed no statistically different (p=0.262). So it can be concluded that olive oil can be recommended as a substitute for xylene in the clearing process in histological tissue processing.
