Changes of Total Antioxigenic Capacity of Plasma and Red Blood Cells in Acute Pulmonary Edema Rats Induced by Formaldehyde Inhalation / 环境与健康杂志

ABSTRACT

Objective To explore the changes of the total antioxigenic capacity (T-AOC) of the plasma and red blood cells (RBC) in the acute pulmonary edema rats induced by acute formaldehyde inhalation. Methods SD rats were randomly dived into the formaldehyde group and control group, then were exposed to formaldehyde and physical saline vapor respectively in a chamber for 2 hours, the actions and vital signs were observed. After treatment the rats were taken out the chamber, 5 hours later, the T-AOC of the red blood cells and plasma were measured and the body, lungs and heart were weighted, the lung /heart weight index and lungs/body weight index were calculated, the pathological examination was done. Results Compare with the control group, the lung weight, lung/body weight index, lung /heart weight index and the T-AOC of the plasma increased, the T-AOC of RBC and body weight decreased significantly(P
