Description

Rat heart dissection operation panel

Technical Field

The utility model relates to a medical science animal experiment technical field specifically says to a rat heart dissection operation panel.

Background

The gene sequence of the nascent rat in the mouse is similar to that of the human, the similarity between the whole genome of the nascent rat and the human is extremely high, and many diseases which are difficult to cure by the human can find similar characters on the nascent rat, so that the disease curing gene is discovered by experiments. The biological significance of the special experimental mouse is large, and the cultured mouse almost has no individual difference (physiologically). Whether there is no individual difference in physiology, meaning that there is no difference in the temperament, is not clear, but the choice of pure-line laboratory mice is primarily intended to minimize the innate individual differences. Furthermore, the number of rats used in the experiment is sufficient, and many experiments require statistical analysis, which requires that a certain number, especially newborn rats, meet the requirement under artificial propagation conditions. Also on an animal scale, newborn rats are also mammals, except for small bodies, and are not inferior to the evolutionary levels of other mammals. The small size of the body becomes the favorable condition for artificial breeding and feeding.

In the field of medical research, heart diseases do not have a single specific symptom, but some symptoms can indicate the possibility of heart disease, but when several symptoms occur simultaneously, a nearly positive diagnosis can be obtained. The doctor first makes a diagnosis by the medical history and physical examination. Laboratory examinations are then used to confirm diagnosis, assess the severity of the disease, and to help develop treatment plans. However, sometimes patients with severe heart disease may be asymptomatic even in the advanced stages of the disease. Therefore, in order to obtain data of the heart in the aspect of pathological changes, the heart often needs to be dissected and researched, and the traditional empirical formula or the data obtained by experience are proved to be one by one through experiments, and more scientific basis is obtained through experimental observation.
