Moreover, activation of macrophages and T cells play an important role in multiple sclerosis (MS).  In the present study, the therapeutic effect of nicotine on experimental autoimmune encephalomyelitis (EAE), an animal model of MS, and its effects on T-helper cells responses was evaluated. Methods: In the present experimental study, EAE was induced by homogenised guinea pig spinal cord and complete Freund’s adjuvant in wistar rats. Animals were allocated in two therapeutic groups (n=7 per group). Treatment with nicotine (2.5 mg/kg-daily) was started in treatment group when the treatment group developed a disability score (at day 12). At the same time, the control group received only the solvent with the same program. Signs of disease were recorded daily until the day 36 when animals were sacrificed. The Splenocytes were checked for proliferation by MTT test and cytokine production by ELISA. The level of nitric oxide in serum was checked by griess test. The data was analyzed using the Student t test and Mann-Whitney U. Results: Nicotine administration in the treatment group significantly reduced the clinical symptoms after the onset of symptoms. Simultaneously with the decrease of the level of serum nitric oxide, nicotine significantly decreased the pro-inflammatory cytokine IL-17 and IFN-γ. The levels of anti-inflammatory IL-10 were not changed significantly. Lymphocyte proliferation was significantly decreased in treatment group compared to control group Conclusion: The results of this study indicated that nicotine had immune modulatory effects and could be used to control MS disease.}, Keywords = { Multiple sclerosis, Experimental autoimmune encephalomyelitis, Nicotine, lymphocyte response}, volume = {21}, Number = {3}, pages = {212-224}, publisher = {Yasuj University Of Medical Sciences}, url = {http://armaghanj.yums.ac.ir/article-1-1214-en.html}, eprint = {http://armaghanj.yums.ac.ir/article-1-1214-en.pdf}, journal = {Armaghane Danesh}, issn = {1728-6506}, eissn = {1728-6514}, year = {2016} } @article{ author = {Ghayedi, N and Khoshnam, SE and Bahaoddini, A}, title = {The effect of Hydro-alcoholic Extract of Licorice (Glycyrrhiza Glabra) Rhizome on the Mechanical Activity of the Colon of Male Rats and its Interaction with Adrenergic System}, abstract ={Abstract: Back ground & aim: Glycyrrhiza glabra (Licorice) is a native medicinal plant of Iran which its rhizome has been traditionally used for treatment of bowel spasm and diarrhea. Accordingly, the present study aimed to determine the effect of the hydro-alcoholic extract of licorice rhizome on mechanical activity of isolated colon of male rats. Methods: In the present experimental study, the colon tissue of 10 adult male rats were dissected and divided into two groups: experimental and control. Each group consisted of 10 strips of tissue. Then, the mechanical activity of tissue strips were recorded by power lab A-D instrument in basal condition, and after administration of phenylephrine and epinephrine and propranolol in the presence and absence of licorice rhizome extract (with effective dose 0.036 mg/ml). Moreover, the mechanical activity of control group strips were recorded at the same condition with extract solvent (ethanol %70). Data were analyzed statistically with using the SPSS software version 19 using Independent-Samples t-test. Result: The mechanical activity of tissue in presence of extract and epinephrine significantly decreased (p≤0.05) compared to the control group. While the mechanical activity in the presence of extract and propranolol significantly increased (p≤0.05) compared to the control group. However, no significant modification was observed in the mechanical activity of the tissue  in the presence of phenylephrine and extract compared to the control group.  Conclusion: According to the present study, it could be concluded that hydro-alcoholic extract of licorice maybe has modifying effect on colon motility via synergist effect with beta adrenergic receptors and independent of the alpha adrenergic receptors.}, Keywords = { Licorice, Mechanical activity, colon, Adrenergic}, volume = {21}, Number = {3}, pages = {225-237}, publisher = {Yasuj University Of Medical Sciences}, url = {http://armaghanj.yums.ac.ir/article-1-1252-en.html}, eprint = {http://armaghanj.yums.ac.ir/article-1-1252-en.pdf}, journal = {Armaghane Danesh}, issn = {1728-6506}, eissn = {1728-6514}, year = {2016} } @article{ author = {zar, A and Hoseini‎, SA ‎ and Amirhosseini‎, SE and Siavashi, N‎}, title = {The effects of eight weeks of endurance training on BDNF, insulin and insulin resistance in rats}, abstract ={Background & aim: Brain-derived neurotrophic factor (BDNF) is one of the most important neurotrophin that it will lead to the development of metabolic syndrome.

Non-coding of long RNA (lncRNA) is a new group of known genes in the human genome transcribed from large parts of the genome of eukaryotes and play an important role in the regulation of different biological processes. The aim of the present study was to compare the expression level of GAS5 lncRNA and NEAT1  in normal and neoplastic samples from breast cancer patients by RT-qPCR. Methods: In the present case-control study, 40 samples from patients with breast cancer tumor and 40 patients from non-tumor under the direct supervision of a pathologist specialist due to clinical presentation and laboratory findings were collected. After extracting DNA from normal and tumor tissues, cDNA synthesis method according to the protocol and RT-qPCR was performed by SYBR®Premix Ex TaqTM II kit.  LncRNA expression levels of genes GAS5 and NEAT1 was calculated using ΔΔCT. Data were analyzed using t-test. Results: The results of Real Time Reverse transcription-PCR indicated that partial expression levels of GAS5 lncRNA gene in tumor samples compared to normal GAS5 lncRNA of the gene, decreasing the expression, and the mean relative expression levels of lncRNA and NEAT1 gene in tumor samples compared to normal was overexpressed. These variation gene expression of LncRNA related to GAS5 about 1.5 times and 2 times to  lncRNA from  NEAT1 gene was observed respectively. Conclusion: Due to the previous reports, these lncRNAs act as tumor suppressor in breast cancer and had differential expression in tumor and normal tissues, which could be used as biomarker for cancer diagnosis.
