The fornix, a part of the Papez circuit, transfers information of episodic memory between the medial temporal lobe and the medial diencephalon （Aggleton and Brown, 1999）. The right medial temporal lobe is known to be specialized for visual memory and the left medial temporal lobe for verbal memory （Tucker et al., 1988; Aegleton and Brown, 1999）.

Ventriculoperitoneal shunting is a commonly used neurosurgical procedure for management of hydrocephalus（jang et al.,2015）.Various complications of ventriculoperitoneal shunting have been reported,including infection,hemorrhage,shunt malfunction,shunt displacement and brain swelling（Kwon and jang,2012,2015）.Although ventriculoperitoneal shunting can cause injury of adjacent neural tracts,little is known about injury of the neural tract by ventriculoperitoneal shunting（Kwon and jang, 2013）.

AIM: To assess the adhesion- and abscess-reducing capacities of various concentrations of polysaccharides derived from fungus, Phellinus gilvus (PG) or Phellinus linteus (PL) in a rat peritonitis ***: In 96 SD rats, experimental peritonitis was induced using the cecal ligation and puncture model (CLP).Rats were randomly assigned to 8 groups; Ringer's lactate solution (RL group), hyaluronic acid (HA group), 0.025%,0.25%, and 0.5% polysaccharides from PG (PG0.025, 0.25,and 0.5 groups), and PL (PL0.025, 0.25, and 0.5 groups).Adhesions and abscesses were noted at 7 d after ***-PCR assay was performed to assess the cecal ***: Adhesion formation was significantly reduced in PG0.25, 0.5, PL0.25, 0.5, and HA groups (2.5±0.7,2.4±0.7, 3.8±1.0, 3.6±0.8, and 2.7±1.1, P＜0.05). The incidence of abscesses was significantly reduced in all treated groups compared to RL group (58%, P＜0.05). The urokinase-type plasminogen activator (uPA) gene expression was greatly up-regulated by increasing the concentration of polysaccharides. The urokinase-type plasminogen activator receptor (uPAR) and tumor necrosis factor (TNF)-α mRNA were highly expressed in PG0.25, 0.5, PL0.25, and ***: We concluded that 0.5% polysaccharide derived from PG and PL was the optimal concentration in preventing adhesion and abscess formation and may act by modulating activity of uPA and TNF-α in a rat peritonitis model.
