ABSTRACT
Objective To observe the changes of water, potassium and sodium in the hypoxic cerebral tissues in mice and the effects of progesterone on the tissues and investigate the neuroprotective role of progesterone (PROG)in the cerebral anoxia. Methods Thirty - two male mice were divided into control group, simple hypoxia group, lower dosage group and higher dosage group. Progesterone was injected intraperitoneally in the dosage of 4 mg/kg or 8 mg/kg respectively 30 min before hypoxia in the last two groups. The contents of water, potassium and sodium in brain tissues in mice were evaluated at 24 hours after cerebral anoxia. Results The water, potassium and sodium contents in simple hypoxia group were significantly higher than those in control group(P0.05)in higher dosage group(8 mg/kg PROG)compared with those of simple hypoxia group. Conclusions At 24 hours after cerebral anoxia, there are significant increases of water, potassium and sodium in brain tissues. Progesterone may pro-duce neuroprotective role by inbibiting the rise of them.
