Influence of Light Environment on the Organic Constitution of Normal Rabbits with Especial Reference to the Action of Neon Light
نویسنده
چکیده
The influence of light environment on the organic constitution of normal rabbits was studied by comparing the weights of organs of animals that had been living under cerrtain conditions for long periods of time. It was found that the light environment produced an effect on the physical constitution of the rabbits which was comparable to the effects produced on the functional activity of the same animals.

متن کاملComparative study of degradation of PP modified with organic pro-degradant subjected to natural and artificial ageing
In abiotic degradation the action of light radiation is one of the most important parameters, because polymers undergo degradation due to the action of light (natural or artificial). The aim of this study was to investigate the degradation rate for samples of polypropylene (PP) modified with an organic pro-degradant submitted to ageing in a natural environment and to accelerated ageing test. Th...
متن کاملThe Influence of Light on Apoptosis in Preimplantation Mouse embryos in vitro
Background: In vitro culture of mammalian embryos can slow or stop growth completely. This may be due to the medium used, pH, temperature, or light. There is considerable concern about the harmful effect of light in the laboratory environment. Cell number and apoptosis are useful parameters that indicate embryonic development and health. In this study, we assessed these two factors in the blas...
