Although we have diverse methods in laboratory studies, such as cellular and molecular sciences, understanding many issues related to human health requires research on animals. An ethical duty of every researcher is to respect animal rights. In our country, educational and research activities are carried out frequently on animals. Therefore, guidelines for ethical use of animals in Iran were de...
There is documented evidence that infection in laboratory animals can often influence the outcome of experiments. All infections, apparent or inapparent, are likely to increase biological variability. As a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 ) and 105 guinea pigs (f...
OBJECTIVE To assess current microvascular training strategies in otolaryngology residency programs. STUDY DESIGN Cross-sectional study. SETTING U.S. otolaryngology residency programs. SUBJECTS AND METHODS A total of 104 U.S. otolaryngology program directors received surveys inquiring about program size, the presence of fellowship training in microvascular surgery, the number of microvascu...
Laboratory exercises are intended to illustrate concepts and add an active learning component to courses. Since the 1980s, there has been a decline in animal laboratories offered in conjunction with medical physiology courses. The most important single reason for this is cost, but other contributing factors include the development of computer simulations, changes in medical education, and press...
FAWVER,AMY L., CHARLES E. BRANCH,LANDATRENTHAM, B. T. ROBERTSON, AND S. D. BECKETT. A comparison of interactive videodisc instruction with live animal laboratories. Am. J. Physiol. 259 (Adv. Physiol. Educ. 4): Sll-S14, 1990.This study compared interactive videodisc-simulated laboratories with two types of traditional labs: a traditional general cardiovascular physiology participation lab and a ...
The 3Rs principle of replacement, reduction, and refinement has increasingly been endorsed by legislators and regulatory bodies as the best approach to tackle the ethical dilemma presented by animal experimentation in which the potential benefits for humans stand against the costs borne by the animals. Even when animal use is tightly regulated and supervised, the individual researcher's respons...
This article adopts a historical perspective to examine the development of Laboratory Animal Science and Medicine, an auxiliary field which formed to facilitate the work of the biomedical sciences by systematically improving laboratory animal production, provision, and maintenance in the post Second World War period. We investigate how Laboratory Animal Science and Medicine co-developed at the ...
Improving laboratory animal science and welfare requires both new scientific research and insights from research in the humanities and social sciences. Whilst scientific research provides evidence to replace, reduce and refine procedures involving laboratory animals (the '3Rs'), work in the humanities and social sciences can help understand the social, economic and cultural processes that enhan...
Epitheliocystis in the carp of a pet fish market were investigated by our diagnostic work and collecting information from department of laboratory animal medicine and fish & shellfish laboratory. The epitheliocystis was identified by using histopathological examination. Epitheliocystis was confirmed as inflammation, epithelial hyperplasia, and lamellar fusion of the gill tissue. Electron micros...
