ABSTRACT
Aim To study the effect of high salt diet during pregnancy on the development of renal vessels in offspring rats and its mechanism.Methods Natural pregnant Sprague-Dawley rats were randomly divided into high-salt group and control group.The pregnant rats in the high-salt group were given high-salt diet of 8% NaCl content , while the control group normal diet with 1% NaCl content.In both groups, pregnant rats were given normal drinking water.After delivery, all mothers returned to normal diet and all neonatal rats were breast-fed until one month old.The adult male off springs were used as experimental animals.The vessel tone of renal interlobar arteries and electrophysiological behavior of single vascular smooth muscle cells (VSMCs) were detected respectively.Results The contractile response of renal arteries to phenylephrine(Phe) in high-salt group was stronger than that in the control group(P0.05).Conclusions High-salt diet during pregnancy could increase the sensitivity of renal interlobar arterial contractile response to Phe in adult male offsprings, which is associated with PKC-mediated BK channels pathway.Maternal high-salt diet during pregnancy may increase the risk of renal vascular diseases in adult offsprings.
ABSTRACT
Objective To evaluate the effect of decompression suction drainage treated mandibular cystic lesions,and compared with the othertreatments such as surgery,decompression,and suction drainage.In order to explore its value in the field of mandible conservative treatment.Methods 36 cases of mandibular cystic lesions were performed decompression and suction drainage.Compared the cystic size before and after the treatment to evaluate the clinical effect.Results According the pathology,29 cases are cyst and 7 cases are mural-ameloblastoma.28 cases which X-ray show a remarkable lessen,6 cases have no change and 2 cases deteriorated.Conclusion decompression suction drainage is one of the ideal treatment for mandibular cystic lesions.
