The Impact of Growing Environment on the Organ Development of White Mice
This essay has applied 6 kinds of different materials, studied the impact of white mice’s growth and their organ development in the feeding boxes which are made of 6 kinds of different materials, such as red-pine plain board, red-pine painted board, veneer particle board, ordinary particle board, formaldehyde painted particle board, and plastic. Discover the indoor microenvironment to be fit for the growth of white mice through dissection, determination and comparative analysis of organ weights. The result indicates that white mice are living in the feeding box made of red-pine plain board whose cardiac index is the highest, the index is in the middle for the one living in the veneer particle board and plastic feeding box, the index is lower for the one living in the red-pine box with painted alkyd varnish and ordinary particle board, and the lowest one is living in the particle board box brushed with formaldehyde; The measured value of white mice’s lungs is highest in the red-pine box. It takes second place in the veneer particle board box, others are in the middle, and the lowest one is in the box brushed with formaldehyde; white mice’s liver index is highest in the red-pine box with painted alkyd varnish, it takes second place in red-pine box without painting, and it is the lowest in the ordinary particle board box and particle board box brushed with formaldehyde; white mice’s thymus index is the highest in the plastic box, it is relatively higher in red-pine box and the red-pine box painted with alkyd varnish, and it is the lowest in the particle board box brushed with formaldehyde; white mice’s kidney index (two kidneys) is the highest in the red-pine box with painted alkyd varnish, and it is the lowest in the particle board box brushed with formaldehyde. This shows that wooden environment has the positive effect on feeding white mice. Rooms in homes are the major place for Man’s living and working. Human beings could spend 2/3 of the whole life in the indoor environment. Along with the social progress, economic development, enhanced living standard, and constantly pursuing the quality of life, people are more and more concerned with the structure of living and working space. Rooms are not merely a shelter from the storm, and the more important is to provide a better working and learning environment as well as a comfortable rest place. Therefore, the quality of the indoor environment is influencing Man’s work and study directly. It concerns Man’s survival and health. Research of the relationships between indoor environment and Man’s survival and health, especially studying the impacts of indoor environment on health of growth and breeding, is increasingly becoming a topic not to be ignored .
