After treatment the right testis of mice removed and fixed. The tissue stained with H&E. In tissues lineage cells of spermatids , epithelial thickness measured. Levels of testosterone , FSH and LH checked out. Data were analyzed with ANOVA and Duncan test. Level significant was p The number of spermatogonia , spermatocytes , epithelial thickness and level of testosterone, FSH and LH in experimental 3 increased significant compared with control group .
Spirulina platensis consumption in male mice increase the number of spermatids , FSH and testosterone.

Inroduction & One of the useful common methods in the study of breast cancer is cellular and molecular studies . Sox-2 play an important role in the differentiation of stem cells and started gene, but the expression of this gene in breast cancer tissue are observed . Therefore, the study of gene expression in cancer tissues of mice treated with phycocyanin from Anabaena sp. ISC55 cyanobacteria, which has anti- tumor and anti oxidant effect is there.
Material and In this laboratory study 50 female Balb/C mice (In bread) prepared and planting methods in the area of breast tumors, was used to induce breast cancer. After from cultivation cyanobacteria in the culture medium BG11, extraction phycocyanin to face proprietary were done and some then with the results from spectrophotometry(UV-VIS), doses of 10 and 150 μl order to treatments groups therapeutic were considered. After from completion periods of 21 days injection, RNA extraction would from tissue and subsequently making cDNA were done and then with the primer by proprietary and witness(Bactin), RT-PCR and electrophoresis was performed, and results were analyzed by softwares SPSS-16 and Image j.
Analysis of the results of RT-PCR technique showed that a dose of 150 ml phycocyanin inhibitory effect on Sox-2 expression in breast cancer cells.
The findings of the present study indicated that phycocyanin from Anabaena sp.ISC55 cyanobacteria has some antitumor effects and can be used in the treatment of breast cancer.

Inroduction & Lung cancer is the most common malignancy and the leading cause of cancer related mortality among women and men worldwide, in such a way that the 5-year survival of patients is about 15%. According to the invasive role of CXCL12, challenges in various studies about expression and non-expression of CXCL12 and the presence of metastasis in early stages of lung adenocarcinoma, the A549 cell line is selected in order to investigate CXCL12 gene expression in it.
Material and In this study A549 cell line was cultured in a DMEM medium contain 10% fetal serum bovine and 1% penicillin- streptomycin. RNA extraction was performed from the mentioned cell line and after qualitative and quantitative evaluation of extracted total RNA, cDNA was synthesized. Then CXCL12 expression was measured using Real time PCR.
CXCL12 low expression in lung adenocarcinoma A549 Cell line shows that it can be considered as a potential marker for predictive and therapeutic purposes.
CXCLL12 has a low expression in A549 cell line.

Inroduction & Anxiety is a common mental disorders among human populations is considered. Due to the side effects of chemical drugs used to treat them, this study aimed to investigate plantago major leaf extract on the level of anxiety in rats was performed.
