Description
Technical field
The present invention relates to the equipment of experimental animal, more particularly, to a kind of laboratory rodent with can independently select to fit
The autonomous daylighting cage box of suitable light environment.
Background technique
Illumination can influence physiology, form and the behavior of various animals, unsuitable periodicity of illumination, intensity of illumination and spectrum product
Matter can all become light stress factor.More and more rodents and primate study show photosensitive retina neural recently
Ganglion cell's (different from retinal rod and the cone) plays important work in terms of adjusting neuroendocrine, circadian rhythm, neurobehavioral
With.Thus, there is illumination in entire animal feeding Qu Douxu, and need suitable illumination to guarantee health benefit and the behaviour of animal
It manages.
Periodicity of illumination plays critical adjustment effect for the reproductive behavior of many animals, should subtract as far as possible in the dark period
Less or avoid carelessness property illumination.It was found that the raising rat under the illumination condition of varying strength is not sent out under the conditions of 151lx
Feelings individual increases, and under the conditions of 1lx, has 40% out of heat.In addition, the sexual cycle of mouse is in regular under the illumination of 20lx
It is 4 day period, then unstable under the conditions of 5lx, 200lx.Due to some animals (such as chicken), it is reluctant under dim light or dark place is searched for food,
Illumination duration should be subject to not induced damage resistive animal health.
Meanwhile lighting device of prescribing a time limit should be used to guarantee the animal regular daily cycle, answer periodic check illumination system
Blanket insurance demonstrate,proves its normal operation.According to the experiment of SD rat, 12 hours light and shade alternate periods, heat is in most stable of 4 day period,
And under conditions of bright 8 hours 16 hours dark, then it is in 5 days or longer sexual cycle.
Common experimental animal is all nocturnalism animal.Wherein albefaction rat is for phototoxicity retinopathy compared with other
Animal is more sensitive.A few houres just will appear retina obstacle at 20,000 lx, and continuous exposure just generates expendable tight for 8 days
It damages again.In addition, illuminating within continuous 7-10 days under 110lx illumination, also will appear light volume cell disorders；Even if being shone in 60lx
Under degree, the rat of raising 13 weeks also will appear retinal degeneration.
