Abstract:Learning anatomy in medical school is still closely based on the use of cadavers. The burial of preserved cadaver poses a problem, specifically, it contaminates the soil with formalin. Many studies have been conducted to find an alternative fixative to update or modify formalin usage. One of them is ethanol-glycerin (EG), which suggests promising results. Despite that fact, there has yet to be any research comparing the decomposition rate between EG and formalin. This study is conducted to compare the rate of … Show more
“…The Department of Anatomy FMUI has developed 4% formaldehyde that can accelerate the decomposition process when the body is buried [3]. Another previous studies from Wijaya et al [4], also developed ethanol-glycerin as an alternative fixative of formaldehyde.…”
Anatomy studies require cadavers to study the human body. Generally in Indonesia, the dead human body will be buried. This causes problems because the decomposition process of a cadaver that is preserved with formalin will be delayed and it causes environmental pollution. The toxicity of formalin can be reduced by neutralizing the formalin. This study aimed to compare the decrease of mice mass that were preserved with formalin then neutralized with sodium bicarbonate and those that were not neutralized. This study used 18 mice (Mus musculus) which were divided into 3 groups. They were the control group (not given preservative), group preserved with 4% formalin, and group preserved with 4% formalin then neutralized with sodium bicarbonate. All groups of mice were buried for 6 weeks. The changes in mass were assessed with an analysis of the percentage loss in mass. Based on the results of this study, the formalin group had a greater percentage of total mass reduction than the neutralize group. The formalin group had a higher decomposition rate than the neutralizing sodium bicarbonate group. The effectiveness of reducing the concentration of formalin is similar with neutralize group. Therefore, it can be concluded that 4% formalin is recommended for use to accelerate the occurrence of decay and decrease in mass.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
