Introduction: A number of researches show anti-proliferative effects of EMF on animal cells. In addition to antioxidant properties of garlic,it contains compounds that can inhibit cell proliferation. This study wasconducted to investigate the effects of garlic extract and EMF with low frequency on angiogenesis. Methods: Eighty fertilized eggs were divided into the control group, sham-exposed 1 (treated by normal saline), sham-exposed 2 (in vicinity of switched off EMF), experimental group 1 (treated by concentration 100 μg/ml of garlic extract), experimental group 2 (treated by concentration 200 μg/ml of garlic extract), experimental group 3 (in vicinity of EMF with intensity of 50 gauss), experimental group 4 (treated by concentration 100 μg/ml of garlic extract and EMF with intensity of 50 gauss), experimental group 5 (treated by concentration 200 μg/ml of garlic extract and EMF with intensity of 50 gauss). On the 8th day of incubation, gelatin sponge was placed on the chorioallantoic membrane and experimental groups 1, 2, 4, and 5 were treated with 10 microliters of garlic extract. On the 10th day of incubation, experimental groups 3, 4 and 5 were exposed to EMF for 4 hours. All samples were photographed on the 12th day of incubation and the length and numbers of vessels were analyzed by ANOVA and Tukey statistical tests. Results: The mean number and length of blood vessels in all experimental groups were significantly decreased compared to the control group (p<0.05). Conclusion: Garlic has inhibitory effects on angiogenesis. Moreover, these effects wereamplified by EMF with intensity of 50 gauss.

Introduction: The expression of neurotrophic factors, which cause increasing of the survival and regeneration of neurons, is changed in response to nerve injury. Cantharellus cibarius has antioxidant and anti-inflammatory effects. So, the aim of present study was to determine the effects of hydro-alcoholic extract of Cantharellus cibarius on expression level of NT3 gene after sciatic nerve compression in rats.

Methods: First the hydro-alcoholic extract of Cantharellus cibarius was prepared by the Soxhlet method. In this study, 36 Wistar male rats , 250-300 gr, were randomly divided into 3 groups consisted of 12 rats in each group. They were control, compression (1, 7, 14 and 28 days) and experimental (1, 7, 14 and 28 days) groups. Experimental groups were treated by 75 mg / kg of hydro-alcoholic extract of Cantharellus cibarius and to induce the stress in control group, saline serum was injected. In compression and experimental groups, the sciatic nerve of right leg was compressed for 60 seconds. The first injection of extract in the experimental group was performed intraperitoneally and immediately after the compression and the second one was injected 7 days later. Then, the sampling was performed of lumbar spinal cord on 1, 7, 14 and 28 days in compression and experimental groups and the total RNA was extracted from the spinal cord segments, cDNA was synthesized and after that the alteration of gene expression of NT3 and NGF samples was studied real time PCR method and Data were analyzed by Tukey test and SPSS 16 softwere.

Results: The expression of NT3 and NGF showed significant increase in compression group compared to the control group, (p<0.05). Also, it is shown significant increase of expression of NT3 and NGF in the experimental group compared to the compression group, (p<0.05).

Conclusion: According to these findings, hydro alcoholic extract of Cantharellus cibarius has an anti oxidant and anti-inflammatory effects that increase the regeneration process expression of NT3 and NGF in the experimental group was increase compared with the compression group.
