Abstract Objective To explore the expression of heme oxygenase-1 (HO-1) in the lung of paraquat poisoning
rats and the protection function of panax notoginseng saponins (PNS). MethodsOne hundred and fi fty SD male rats were
randomly divided into 3 groups: normal control group (group C, n=30), paraquat poisoning group (group PQ, n=70), and drug
intervention group (group PNS, n=70). The groups PQ and PNS rats were given paraquat by gastric perfusion (25 mg/kg);
The group C rats were given saline by gastric perfusion. The rats in group PNS were protected by intravenous injection on
penis with PNS (50 mg/kg) for 15 min before exposure of paraquat once a day until they were killed. The groups PQ and C
rats were given saline. Histological changes of lung tissues under light micr
