OBJECTIVE： To investigate the effect of Ganoderma lucidum spore powder on expression of insulin-like growth factor-1 （IGF-1）, nuclear factor-κB （NF-κB） and neuronal apoptosis in rats with pentylenetetrazol （PTZ）-induced epilepsy. DESIGN, TIME AND SETTING： A cellular and molecular biology experiment with randomized controlled study design was performed at the Central Laboratory of Basic Medical College of Jiamusi University from June to August 2005. MATERIALS： Thirty healthy, adult, male, Wistar rats were selected and randomly divided into 3 groups （10 rats per group）： control, epilepsy model, and Ganoderma lucidum spore powder. A sub-eclampsia PTZ dose （35 mg/kg） was intraperitoneally injected to induce epilepsy in the latter two groups. Wild Ganoderma lucidum spore powder （30 g/L） was provided by the wild Ganoderma lucidum plant nursery at Jiamusi, China. Immunohistochemical detection and terminal deoxynucleotidyl transferase-mediate dUTP nick end-labeling （TUNEL） kits were purchased from Wuhan Boster Biological Technology Co., Ltd., China. METHODS： Ganoderma lucidum spore powder was intragastrically administered at a dose of 10.0 mL/kg, once a day for 28 days. In the epilepsy and control groups, an equivalent volume of normal saline was intragastrically administered. MAIN OUTCOME MEASURES： Immunoreactivity for IGF-1 and NF-κB/P65 were detected by immunohistochemical staining. Neuronal apoptosis was detected using TUNEL methods. RESULTS： The hippocampus and cerebral cortex of rats with PTZ-induced epilepsy exhibited a higher number of apoptotic cells at high magnification （×400）, compared with the control group. Expression of IGF-1 and NF-κB were higher in the epilepsy group, compared with the control group （P 〈 0.01）. In Ganoderma lucidum spore-treated rats, fewer apoptotic cells were observed in the hippocampus and cerebral cortex, expression of NF-κB/P65 was lower, and immunoreactivity to IGF-1 increased more distinctly, compared with the epilepsy group. In addition, seizure latency was longer on 17, 21, and 25 days post-PTZ treatment in the Ganoderma lucidum spore powder group, compared with the epilepsy group （P 〈 0.05-0.01）. CONCLUSION： Ganoderma lucidum spore powder down-regulated expression of NF-κB in brain tissues of rats with PTZ-induced epilepsy, increased immunoreactivity to IGF-1, and inhibited neuronal apoptosis. These results indicated that Ganoderma lucidum spore powder has a neuroprotective effect.展开更多
