Occupational asthma induced by ganoderma spores / 천식및알레르기

Occupational asthma induced by the inhalation of the spore of Ganoderma lucidum was demonstrated in a 43-year-old woman who had cultivated it indoors for 6 years. She had suffered from paroxysmal cough and rarely wheezing dyspnea for two years. Recently she also had chest tightness and paroxysmal and repeated cough immediately after the exposure to Ganoderma lucidum spores. Her pulmonary function was normal. But, her PC20 was 6.4mg/ml in MBPT (methacholine bronchial provocation test). She showed not only positive reaction to skin prick test but also dual asthmatic reaction to the bronchial challenge test with antigenic extract of Ganoderma lucidum spores.

Effect of Ganoderma lucidum spores on IL-1? and c-Fos in the brain tissue of epilepsy rats / 中国病理生理杂志

AIM: To observe the influence of Ganoderma lucidum spores on the cytokine IL-1? and c-Fos in the brain tissue of epilepsy rats. METHODS: The IL-1? level was examined by radioimmunoassay and the c-Fos expression was measured by immunohistochemical assay. RESULTS: Comparing the Ganoderma lucidum spores group with the epilepsy model group: c-Fos positive cell count in brain cortex and hippocampus in treatment group was obviously reduced. IL-1? level in brain tissue was also reduced obviously. CONCLUSION: Ganoderma lucidum spores effectively reduces cytokine IL-1? in brain tissue of epilepsy rats, improves the immunity dysfunction and plays a role in anti-epilepsy through suppressing c-Fos expression in epilepsy rats brain tissue and blocking of LRG.

Effect of Ganoderma lucidum spores powder on the expression of IGF-1, NF-?B and apoptosis of nerve cells in the brain from epileptic rat / 中国病理生理杂志

AIM: To investigate the effect of Ganoderma lucidum spores powder on the expression of insulin-like growth factor-1 (IGF-1), nuclear factor-?B (NF-?B) and apoptosis of nerve cells in rats with epilepsy established by pentetrazole. METHODS: The sub-eclampsia dosage of pentetrazole (PTZ) was used to make epilepsy model. Ganoderma lucidum spores powder group was given from stomach. The enduring time and latent period were recorded. The immune reactivity of IGF-1, NF-?B/P65 and apoptosis of nerve cells were measured with immunohistochemical staining and TUNEL method. RESULTS: In high power sight (?400), there were much more apoptosis cells in hippocampus and brain cortex of model group (18.80?2.13, 16.87?2.00) than those in control group (0.97?0.52, 0.58?0.25). The expressions of IGF-1, NF-?B in model group were higher than those in control group. Compared with model group, the latent period of Ganoderma lucidum spores powder group at the 17th, 21th, 25th days were longer (P
