Abstract
Objective: A new aldehyde-free fixative has been developed and its effect has been compared to traditional formaldehyde fixative in terms of the fixation effect and HE staining of the heart, liver, lung, and kidney. The air in the experimental area was examined to evaluate its impact on the environment and human health.
Methods: The organs from mice of groups 1-6 were taken respectively (thickness of liver and lung was 3 mm). After the heart and kidney capsule were removed, the organs were longitudinally cut along their maximum surface, and half was taken. Thereafter, the tissue fixation effect was observed by Hematein and Eosin (H＆E) staining and the total protein content of tissue was examined by the ultramicro spectrophotometer. Additionally, the volatility ratio of the new fixative and the traditional formaldehyde is compared.
Result: The results showed that there was no significant difference between the fixation effect of the new aldehyde-free fixation and the traditional formaldehyde fixative on mouse organs and the air quality in the experimental area was found to be significantly better when the new aldehyde-free fixative is used than when the traditional formaldehyde fixative is used.
Conclusion: Traditional formaldehyde fixative in HE staining can be replaced by the new environment-friendly formaldehyde-free fixative, however further special staining of fixed tissue and immunohistochemical studies are needed.
期刊介绍：
Launched in 1995, Alternative Therapies in Health and Medicine has a mission to promote the art and science of integrative medicine and a responsibility to improve public health. We strive to maintain the highest standards of ethical medical journalism independent of special interests that is timely, accurate, and a pleasure to read. We publish original, peer-reviewed scientific articles that provide health care providers with continuing education to promote health, prevent illness, and treat disease. Alternative Therapies in Health and Medicine was the first journal in this field to be indexed in the National Library of Medicine. In 2006, 2007, and 2008, ATHM had the highest impact factor ranking of any independently published peer-reviewed CAM journal in the United States—meaning that its research articles were cited more frequently than any other journal’s in the field.
Alternative Therapies in Health and Medicine does not endorse any particular system or method but promotes the evaluation and appropriate use of all effective therapeutic approaches. Each issue contains a variety of disciplined inquiry methods, from case reports to original scientific research to systematic reviews. The editors encourage the integration of evidence-based emerging therapies with conventional medical practices by licensed health care providers in a way that promotes a comprehensive approach to health care that is focused on wellness, prevention, and healing. Alternative Therapies in Health and Medicine hopes to inform all licensed health care practitioners about developments in fields other than their own and to foster an ongoing debate about the scientific, clinical, historical, legal, political, and cultural issues that affect all of health care.
