ABSTRACT
Craniopharyngiomas develop from remnant epithelial cells of Rathke's pouch in the sella/parasella region with low histological grade. Clinical manifestations are related to visual impairment, increased intracranial pressure, and hypothalamic/pituitary deficiencies, including vision loss, headache, nausea, growth retardation, and hypogonadism. Despite benign epithelial tumors, craniopharyngiomas are adjacent to critical brain structures including hypothalamus, pituitary stalk, chiasma opticum and have recurrence tendency. Treatment-related complications including hypothalamic/pituitary deficiencies, diabetes insipidus, and hypothalamic obesity are major risk factors for reduced quality of survival and throw out a great challenge to the surgical treatment and the postoperative management. Clinical features of one case craniopharyngiomas with manifestation of severe hypopituitarism are described with the aim of exploring effective therapies.
ABSTRACT
Objective To investigate the preventive effect of nano-powder of Wugong-sanqi (NW),the rhizome of Anemone flaccid,on postoperative intestinal adhesion in rats.Methods Fifty SD rats were subjected to operation with Ellis' method for establishing intestinal adhesion models,then randomly divided into 5 groups (n=10),namely model,positive (Dexamethasone,i.m.10 mg/kg),NW high,medium and low dose group (p.o.450,225 and 112 mg/kg,respectively).Another ten normal rats were selected as normal control group.After administration 3 days pre-operation and 7 days post-operation,all of rats were killed,the intestinal adhesion was graded and the tissues were observed by optical microscope.Results NW evidently reduced the severity of postoperative adhesion (P＜0.05 or P＜0.01),compared with model group.The histopathologic changes such as proliferation of fibroblast cells and capillary,interstitial granulomas and inflammatory cells infiltration in intestinal tissues were also improved significantly in NW groups.Conclusion NW could inhibit the formation of postoperative intestinal adhesion effectively.
