Artemisia sieberi is a plant from chicory category which is a green crucible and it is from the growing elements of Iran and Turani and it is from the prevailing elements of the Stopy pasturage of Iran too. The application of this plant in the field that isnt for grasses is so much various because of its expressed juice content. Antibiotic property of this plant is used in ancient medical to cure the abnormal digestion and to ward of the intestinal parasites. The purpose of this study is considering of antimicrobial effect of the expressed juice of this plant in different grazing conditions on the Salmonella enteritidis that create illness. This bacterium is one of the agent of intestinal infections. In this research the growing of Artemisia in current year from available sites have colleted in two different has been sites which in one of them the action of grazing done and in the other one the grazing action hasnt been done then the expressed juice of this plant has been provided and its antimicrobial effect in 6 attendances along with its medicine properties which is provided in a diluted condition an the creating illness bacteria of salmonella have been accomplished by using the spreading disk method in related to the assessing the antimicrobial property in different densities. The results of this research showed that the grazing factors had no effect on different combinations of antibacterial of expressed juice of Artemisia sieberi but antimicrobial effects of this plant relies on the grazing variable. The main environment of this plant is Muller Hinton Agar and the results of this research have many applications in food and medicine industrials.

An eight-year-old, female holstein cow, weighting 457 kg was presented with a 7.5×5×8 cm plaque on the surface of the vagina. The mass was removed surgically and Squamous Cell Carcinoma (SCC). Immunohistochemically, positivity for AE1/AE3, CK5/6, CK8 and PCNA revealed that this tumor was originated from keratinocytes and high grade. Therefore Immunohistochemistry can help the clinicians in Prognosis and Treatment of referred Cases.

A survey was carried out to investigate the occurrence of Sarcocystis spp. and identification of Sarcocystis hominis slaughtered cattle's in Isfahan slaughterhouse. In all, the muscle tissue (cardiac and diaphragmatic muscles) of 768 samples from 384 cattle carcasses were examined by microscopic method. Based on the microscopic examination the prevalence rate of Sarcocystis cysts in the cattle's were 62.8%. Based on the PCR method, 207 sample from 431 infected samples (48.1%), were positive for Sarcocystis hominis. Not significant difference was observed between the prevalence in cardiac and diaphragmatic muscles (P>0.05). The results indicated that Sarcocytsis cysts in the Isfahan is consumption of under–cooked cattle meat may result in Sarcocytsis in humans.

Marine pollution is one of the main concerns of countries surrounding the Persian Gulf which receives a great deal of contaminations such as petroleum chemicals and heavy metals daily. In this regard, histological changes in gill were used as a biomarker to evaluate the health of the marine fish species Liza abu, collected from different sampling sites in Mussa creeks. In the present study, 50 L. abuwere collected from different sampling sites in Mussa creeks including: 1. Petrochemical, 2. Gaafari, 3. Magidieh, 4. Ghazaleh and 5. Zangi. The gills of fish were fixed in Bouin‘s solution for 12 h. Five-micrometer thick sections were obtained and were stained in hematoxylin/eosin for examination in light microscopy. Pathological changes in the gill of Liza abu species including hypertrophy and hyperplasia of the lamellar cells, oedema, lamellar fusion, increase of mucus and chloride cells. Histopathological alteration index was determined on the basis of frequency of pathological changes in gill species Liza abu. The most amount of HAI for gill were observed at the Petrochemical station (p

The extract of the bark of Albizia lebbeck obtained by cold extraction of mixture of equal proportions of petroleum ether, ethyl acetate and methanol was chosen for pharmacological screening. Each group consisted of 6 rats. In rat paw edema model induced by carrageenan, the extract at the 400 mg/kg dose level showed 36.68% (p

Effects of Toxic in chemotherapy and radiotherapy are followed by many changes in male reproductive system. Melatonin, one of the secretions of Epiphyses, known as an antioxidant. The aim of this study is the investigation of protecting effect of Melatonin on the disordering of spermatogenesis resulted in the Jemcitabin – therapy by analyzing the histology of testis. Samples in this experimental intervened study are 48, 8weeks aged male wistar rat .Samples randomly divided in 6 groups with 8 rats. control group affected by normal Saline (IP) Group 2,3Melatonin injected mono dosage (IP) in10, 20 mg/kg quantity Group 4 Jemcitabin injected mono dosage (IP) in 50 mg/kg quantity Group 5,6 Jemcitabin Melatonin injected jemcitsbin in 50mg/kg and melatonin10,2 mg/kg (IP) in IP manner 14 days after therapy, the symbols made unconscious and segregate the rats`testis and assessments was composed through the study of seminiferous tubules and counting of spermatogenic and somatic cells. Quantitative variables was evaluated and analyzed through non-parametric Kruskal-wellis by the help of SPSS, supposing p

Perlite is among silicon volcanic stones and posses a neutral pH and had been admitted in the chemical direction of food. An experiment was conducted to study the effects of perlite on morphology of villi in the small intestine of male broilers. The experimental design was arranged as randomized complete bocks in 4 * 2 factorial arrangement of treatment. 120 male broilers of Ross commercial hybrid (Ross 308) was designated into 2 groups (control and treatment). 3 replicates of 20 birds were assigned to each treatment. Control treatments were fed base diet and treatment with the same base diet plus 2% perlite. Animals were slaughtered and different segments of small intestine(at1,10,30,50,70 and 90% of total length the small intestine) were taken from each replicates (N=2). Morphology of villi was measured and recorded. Data were analyzed by SAS (P

Fungi like Fusarium species that have generally been referred to as farm fungi, in terms of toxicity and toxin production are prominent in their group. The most important fumonisin toxin is fumonisin B1. Fusarium toxins are generally produced at lower temperature than optimum growth temperature. Fumonisin is a toxin produced by Fusarium verticillioides. In recent years due to ecological changes and increased soil nitrogen levels, fusarium contaminations have increased. In present study effect of essential oil (EO) of Cuminum cyminum on Fusarium verticillioides isolated in Iran were determined in vitro by micro dillution method. The main EO active ingredient of Cuminum cyminum is aldehydecuminic. This EO is water soluble. This research was performed inon14 isolated. The drug sensitivity tests were performed according to standard methods Broth Micro dillution NLCCLS-M38A2. The tests were repeated twice. MIC (Minimum inhibition concentration) frequency of EO was 0.195 μg/mlwith42.84% susceptible isolate and the least frequent was in concentration0.293μg/mlwith7.14% susceptible isolate. MFC (Minimum fungicidal concentration) frequency distribution was0.39 μg/ml with 42.84% susceptible strains and lowest frequency of susceptible isolate were 0.146, 0.293and0.586 μg/ml with 7.14%. The results indicate effectiveness of this essential oil inhibited the growth of Fusarium verticillioides. EO effect on transformation the fungus conidia were proved by microscopic examination. MIC and MFC of cuminum cyminum EO on different isolate of F. verticillioides were calculated 0.097-0.39μg/ml and 0.146-0.78 μg/mlrespectively.
