Abstract:
Objective To study the influence of environment oxygen supplement and passive smoking on the blood gas indexes in rabbits.Methods Eighty adult Newzealand white rabbits were randomly divided into 4 groups,20 in each.The oxygen supplement and passive smoking group was exposed to cigarette smoke produced by 25 burning cigarettes,four hours per time,consecutively for twenty-four hours,simultaneously exposed to oxygen produced by two oxygen generators(600-1 000 ml/min per generator).The oxygen supplement group was exposed to oxygen produced by two oxygen generators(600-1 000 ml/min per generator) consecutively for twenty-four hours.The passive smoking group was exposed to cigarette smoke produced by 25 burning cigarettes,four huors per time,consecutively for twenty-four hours.The control group was exposed to general feeding environment.The analysis of variance of factorial design(2?2) was conducted,five blood gas indexes were measured.Results Under the condition of surroundings oxygen increasing,the partial pressure of blood oxygen was improved significantly(P0.05).No evident interaction was found between surroundings oxygen increasing and passive smoking.Conclusion Oxygen metabolism can be improved by environment oxygen supplement in rabbits,and the effect of passive smoking on the investigated five blood gas indexes is not considered significant.
