ABSTRACT Formalin fixation is the most essential step of routine histopathology practice. During the last few years, various fixatives have been developed for use in histopathology practice as an alternative to formalin, to overcome its side effects on health. Here we have demonstrated an interesting and novel idea of using sirka or sugar cane vinegar as an alternative to the formalin with the adequate result.

Formalin embalming method is cheaper and commonly used. Thiel method is said to be complex, expensive, not commonly used but offers better cadavers for student teaching. The study aimed at exploring the effects of two embalming methods; modified Thiel and formalin methods on cadavers in terms of muscle softness, joint flexibility, tissue colour, formalin smell and the ease with which structures can be identified. This was an experimental study design done over the period of three months where four adult male cadavers were embalmed (two under each method) and the outcome was compared. Using gra

Abstract Introduction Fixation is the critical step in the preservation of tissues in diagnostic pathology. The formalin is an economical and excellent fixative with the inherent property of adequate fixation. The well-established side effects of formalin include mucosal irritation, upper respiratory diseases, and corrosive injury to the gastrointestinal tract. In addition, substantial evidence exists regarding the potential role of formaldehyde as a human carcinogen. The carcinogenic and toxic effects of formalin encourage searching for alternative fixatives for tissue fixation. However, “the

Extracted human teeth provide the closest approximation to teeth in situ and play important roles in dental education and materials research. Since extracted teeth are potentially infectious, the Centers for Disease Control recommend their sterilization by autoclaving or disinfection by formalin immersion to ensure safe handling. However, autoclaving is not recommended for teeth with amalgam fillings and formalin is hazardous.

Formalin-acetone sedimentation was compared with the formalin-ether method for the concentration of stool for intestinal parasites. Of 80 stool specimens, 45 (56.25%) were positive for parasites by the formalin-acetone method. The figures for the two methods were formalin-ether 35 (43.75%) and for the direct lacto-phenol cotton blue wet mount method 17 (21.25%). There was no statistically significant difference in the parasite recovery rate between the two methods. Acetone is more stable, safer, and a cheaper fat solvent and promises to be a useful alternative to ether.

Abstract This study aims to formulate an alternative solution for Formalin for preserving fish as study specimens for long periods. The main reason for finding a solution instead of formalin is to get rid of the negative effects of this solution on those who work with it, as well as to better preserve the bodies of fish. Hence, three new solutions were proposed to replace formalin. Thus, Formalin, in turn, may enter the composition of a small part of these solutions to give better results and for long periods of keeping specimens.

The high protein content of beef makes it easy to get a contamination caused by an activity of bacteria. The use of formalin as a preservative substance especially for beef can make a damage to health, so it is required to find preservative substances as alternative to substitute formalin. Mengkudu (Morinda citrifolia L.) has antibacteria compounds to the decompose bacteria of beef, so mengkudu fruit can be o

Tissue preservation plays an essential role in biomedical research and histopathological applications. Traditional methods, despite their efficiency, are associated with compromised long-term tissue integrity and probable ecotoxicities. This study explores the application of silver nanoparticles (AgNPs), known for their antimicrobial properties, as a potential tissue preservative. In this work, AgNPs were synthesized via a chemical reduction method. Heart, liver, and kidney tissues were obtained from BALB/c mice and preserved using 10% neutral buffered formalin (NBF) and AgNPs solution for 72

Background: Formalin has been used as a standard fixative for various clinical routines globally. In 1987, after formaldehyde was used as a standard, various studies have been conducted to find a substitute for formalin due to its carcinogenic effects. Since then honey has been proven to be a safe alternative to formalin. Objective: Comparing the tissue fixation abilities of honey, Carnoy’s, Bouin’s and Zenker’s solution with the tissue fixation abilities of formalin using eosin, hematoxylin and Masson trichrome periodic acid Schiff is the objective of this study.

Biological specimens are essential for teaching, research, and extension, although they require effective preservation. The glycerination technique stands out for allowing specimens to be preserved dry, which saves costs and facilitates handling due to specimen malleability. We sought to establish an optimal glycerination protocol for fish and reptiles for teaching purposes. Several fixatives were tested, including formalin at different concentrations and Transeau solution. The fixation process involved injecting a 50% fixative and 50% double-distilled glycerin solution into the specimen, foll

We previously reported that intracerebroventricular (i.c.v.) administration of PD showed an antinociceptive effect as measured by the tail-flick assay. However, its exact role in the regulation of antinociception in the various types of pain models has not yet been characterized. Thus, we attempted to find antinociceptive profiles of PD in various pain models. PD administered intraperitoneally (i.p.), i.c.v. or intrathecally (i.t.) showed antinociceptive effects in dose-dependent manners

Abstract Context.—Expression profiling by microarrays and real-time polymerase chain reaction–based assays is a powerful tool for classification and prognostication of disease; however, it remains a research tool, largely reliant on frozen tissue. Limiting the utility of expression profiling is the isolation of quality nucleic acids from formalin-fixed, paraffin-embedded tissue. The collection, handling, and processing of tissue directly impacts the biomolecules that can be recovered from it. High-quality nucleic acids can be obtained from formalin-fixed, paraffin-embedded tissue, but greater
