Abstract:
Objective To establish the advanced lung cancer model with effusion in the pleural cavity by implanting the lung adenocarcinoma A549 cells into the lung and pleural cavity of mice.Methods The Balb /c-nu female mice were divided into three groups and injected with the subculturing lung adenocarcinoma A549 cells to make three models in the subcutaneous (group A),the lungs (group B) and the lungs and pleural cavities (group c).The survival time,weightconsume of feeds,signs and symptoms of cachexia,growth of lung cancer and pleural effusion were observed.Results The median survival time in group C and group B were obviously reduced compared with group A.The range discrete in the group A was higher than group B and group C.There was no significant difference between group B and group C in the average survival time.The effective survival time was significant different between group B and group C.There were differences among three groups in the signs and symptoms of cachexia,the weight and consume of feeds.In 4 weeks,the rate of growing effusion in the pleural cavity was 93.3％ in group C,and only 20.0％ in group B.Conclusions The mice modal implanted the lung adenocarcinoma A549 cells into the lung aud pleural cavity of mice in the same time can be as the adwanced lung cancer model with effusion in the pleural cavity.
