Abstract

Introduction

Hydrocephaly is a disease that affects not only the dynamics of the cerebrospinal fluid, but also other structures of the central nervous system. Although shunt is effective in reducing ventriculomegaly, many neurological damages are not reversed with surgery. Several studies demonstrate that oxidative stress is involved in the genesis of hydrocephalus lesions.

Objective

Evaluate the neuroprotective response of quercetin in hydrocephalus.

Materials and methods

Male newborns rats were used, which received the 15% kaolin injection in the cisterna magna for induction of hydrocephalus. They were divided into control group (C), untreated hydrocephalic (HN), shunted hydrocephalic (HD), hydrocephalic treated with distilled water (HA), hydrocephalic treated with distilled water and shunt (HDA), hydrocephalic treated with quercetin peritoneal (HQp), hydrocephalic treated with quercetin peritoneal and shunt (HDQp), hydrocephalic treated with quercetin by gavage (HQg), and hydrocephalus treated with quercetin by gavage and shunt (HDQg).

Results

Quercetin significantly improved the immunohistochemical markers, mainly caspase and GFAP. There were no significant changes in clinical/behavioral assessment. The use of isolated quercetin does not alter the volume and ventricular size, and the realization of ventriculo-subcutaneous shunt in newborn rats with hydrocephalus presents a high morbi-mortality.

Conclusion

The use of quercetin shows laboratory improvement of the effects of glial lesion and corpus callosum fibers and is therefore not justified by the use of the routine substance as neuroprotective.
