Scientists working with pythons Python molars, grown in the laboratory. In the wild these snakes eat very irregularly - snakes can fast for weeks before they catch prey, sometimes quite large. To digest the "sudden" food, the body is undergoing a significant restructuring of pythons - the metabolic rate increases 40 times, and the size of many organs, including intestines and heart, is doubled. These changes are necessary in order to distribute the huge amount of incoming nutrients throughout the body.
Shortly after the python swallows its prey, it is filled with the blood of different fatty acids. Scientists have suggested that some of them may contribute to an increase in heart size. To test this hypothesis, the specialists were injected blood plasma obtained from just polished pythons, their hungry brethren. As a result of this procedure, the heart of the latter increased significantly in size, reports Lents.Ru.
In subsequent experiments, scientists tested the "works" is a cocktail of fatty acids as an elixir of growth of other living creatures. It clarifies the New Scientist; scientists have added to the blood plasma of pythons to cell cultures of mouse hearts and found that while the cells begin to produce more intense insulin-like growth factor 1 - a hormone that promotes an increase in the size of organs. In addition, the cells themselves essentially "grown up".
Substances that stimulate the growth of the heart, similar to that which occurs in python would be very much in demand in medicine for the treatment of cardiovascular disease. It is particularly important that the enlargement of the heart under the influence contained in the blood plasma of python’s compounds occurs without scarring. Scars resulting in local stretching of the heart muscle in people who cannot be reduced, and consequently, the efficiency of the heart is reduced.
