Objective To investigate the affects of aerobic endurance training on the endocrine function of the cardiovascular under the different conditions of unexposed and exposed to nonylphenol(NP) in the rats.Methods Seventy-two rats were randomly divided into 8 groups: unexposed control group,unexposed training control group,the low,moderate and high dosage quiet exposed groups,the low,moderate and high dosage training exposed groups,nine rats in each group.The training group without loading aerobic endurance swimming,the low,moderate and high dosage exposed to NP at doses of 11,44,176 mg/kg,respectively,the concentrations of plasma of atrial natriuretic peptide(ANP) for each group were determined during the experiment.Results ANP of the training control group was significantly increased compared with the quiet control one(P0.05),but the moderate and high dosage ones presented obvious decreasing trend than the unexposed control one(P

Objective To analyse the possible reasons of early hydrocephalus after surgery for posterior cranial fossa tumors,and put forward the preventive messures against this complication.Methods Clinical data of 18 cases of early hydrocephalus after surgery for posterior cranial fossa tumors were analysed retrospectively.Results All the patients were in good state within 24 hours after surgery,but a series of symptoms,such as disturbance of consciousness,headache and vomiting,occurred.CT scanning showed hydrocephalus.After the comprehensive treatment including ventricular duainage,16 patients were healed.2 cases died.Conclusions Post-operative cerebellar edema,intracranial hematoma or hydrops,residual tumor,might be the possible cause of this disease.Preventive messures against this complication might include protecting brain tissues during operations,hemostasis and comprehensive treatment after operations.
