Although numerous factors participate in pain sensation, effcient studies have never been done on these factorsyet. Among these factors modifying effect of Electro Magnetic Field (EMF) on both intensity and duration of painsensation is undeniable.This study has been done on two groups of mice In order to investigate the effect of electromagnetic felds on visceralpain. The frst group were exposed to EMF (one hour in a day for 7 days), where as the second group weren’t. Bothgroups were treated with the acetic acid Intra-Peritoneally for measurement of visceral pain separately.The results revealed that Exposure of mice to electromagnetic feld led to in signifcant and considerable reductionof visceral pain sensation. Understanding the mechanisms creating analgesic effects of electromagnetic feldsrequires further studies.

In this experiment 144 Hy- line (W36) laying hens were used from 65-76 weeks of age in 4 treatments, 3 replicatesand 12 hens in each replicate in a completely randomized design. Experimental groups included: 1) control group,2) 2.5% of apple wastes, 3) 5% of apple wastes, 4) 7.5% of apple wastes. The results showed that using apple wastehas signifcant effects on performance, egg quality and blood parameters of commercial laying hens (p<0.05). Thehighest amounts of egg weight and egg mass, the highest egg production percentage, the best feed conversion,and the lowest price of feed intake for production per kilogram of egg were resulted by using 5% of apple waste.Using 7.5% of apple waste signifcantly decreased the amount of feed intake. Using more than 2.5% of apple wastein laying hens diets had adverse effects on egg traits. In this case the percentages of eggshell, egg yolk, Haughunit and eggshell thickness decreased. The lowest level of blood cholesterol was resulted by using 2.5% of applewastes, whereas the highest level of lymphocyte was obtained by using 5% of apple wastes. The overall resultsshowed that using 5% of apple wastes improve the performance of laying hens, however using more than 2.5% ofapple waste has adverse effects on egg traits.

The aim of in this study was effect of different level replacement soybean meal and canola meal and its effectin Dry matter, production and milk composition Glocose and BUN of dairy cow. here of 24 Holstein cows wereselected randomly.Treatments were diets containing different levels of 0,5,10 and 15 percent rapeseed mealwas replaced with soybean meal. Then The blood and milk samples from cows were then and Analyzed by Sasand Glm.The results showed no signifcant differences between any of the treatments (P≥0.50) in case of milkprotein percentage, fat percentage, the percentage of lactose, glucose levels and blood BUN. Effect of time on allcomponents of the study was signifcant (P≤ 0.50).The test results showed that the soybean meal with canola mealwithout detrimental effects on production parameters and blood metabolites in dairy cows fed soybean meal wasreplaced every level.

Wound healing has always been of great concern for the surgeon and therefore using different effective biologicalsubstances of either plant or animal origin for a faster and more effcient wound healing (repair) has been considered.The aim of this study was to investigate the accelerating effects of Hypericumperforatumhydroethanolextracton open wound healing in rats. Study design: thirty-six adult male Wistar-albino rats (weight 200±10 g) wererandomly allocated to three groups (one control and two treatment groups). Two seven-mm, circular, fullthicknesses, skin wounds were created on the back of each rat (2 on the left and 2 on the right side). In the controlgroup, wounds were treated by an ointment with no extract. The treatment groups were treated by standardizedointment containing 1% and 2% Hypericumperforatum extract. For histopathological studies, the 3 groups weresubdivided into 4 subgroups with 4 rats in each. Samples were taken from the groups 1 to 4 on days 3, 7, 14, and21, respectively. After taking the sample, the rats were euthanized. The sequential wound biopsies were evaluatedhistopathologically for their heamorrage,neutrophils and lymphocyte, new vascularization and re epithelialization.According to the results of this study, the ointment with 2% extract was much better and slightly better than thecontrol and 1% extract ointments, respectively.

The composition of diet can influence morphological features of intestines which may lead to changes in digestion and absorption of nutrients.The present study evaluates the histomorphometric changes of small intestine due to Zataria Multiflora in broiler chickens. To this end, Fifty, one-day old chickens were randomly divided into fve equal groups and fed with diets contained 0.5, 1, 1.5, and 2% of Z. multiflora (experimental groups) or basal diet (Control Group) for 40 days. At the end of the treated period, all animals were weighted and sacrifced. Small intestine was removed from the bodies immediately after death; transverse sections were successively cut with 2cm intervals and fxed in 10% buffered formalin. The sections were stained with H&E, and then studied under light microscope. Height and width of villi, depth of crypts, and width of sub-mucosal and muscular layer were measured by linear Graticule, then data were analyzed by using the ANOVA statistical test. The result showed that, villus height, crypt dept, and villus height/crypt dept ratio as well as submucosal and muscular layer width did not signifcantly changed in the experimental groups as compared to control; this indicated either the lack of any change in intestinal absorption or the weights of the experimental chickens as compared to the control. In conclution, the consumed ration of Z. Multiflora that used, could not effect on absorption ability via intestinal histological changes.

Hydatid cyst and fasciolosis are zoonotic diseases without a specifc clinical sign. Final diagnosis in animals can be made only by necropsy and post mortem insepction. Undoubtedly, hygiene of slaughterhouses has upstanding correlation with Community hygiene and health, fewer no attentions to this subject will follow more hazards to the people of society. Total liver and lungs of the slaughtered Sheep and goats in Gachsaran slaughterhouse were studied .Overall 3082 of sheep cases and 7873 goat cases slaughtered in summer season. A total of 11753 of liver and lung studied, 1153 samples deleted and out of consume cycle. The results showed that liver of sheep and goat infected (9.99% Fasciola, 6.20% hydatid cyst, abscess 3.46%); (9.27% Fasciol ,9.60% hydatid cyst, 3.91% abscess) respectively, (12.86% Pnemonia and permia, 4/96% hydatid cyst, 5.81% abscess); (16.98% pnemonia and permia, 4.76% hydatid cyst, 12.14% abscess) obtanined in lung of sheep and goats respectively. As a conclusion, so more attention of related control organizations seems to be needed.

A seven month male Boxer dog, 15 kg body weighting has been referred to private small animal clinic with left forelimb palmigrade stance. The history of trauma was not reported and patient also did not suffer from any systemic disease. Left forelimb (lateral view) stress radiograph was shown hyperextension at the antebrachiocarpal joint. Then based on history and clinical examination surgical treatment of pancarpal arthrodesis was performed. The postoperative care was antibiotic administration and limb was supported in a cylinder cast at least for 8 weeks. The hyperextension of the carpus is the serious injury to the canine carpus and pancarpal arthrodesis involves surgical fusion of all joint levels. This has been a satisfactory limb sparing procedure in comparison to limb amputation.

The aim of this survey from summer of 2012 we muster about 50 number of common carp (Cyprinus carpio) from Aras dam in west Azerbaijan province and them isolated a parasite that name is Anisakis sp. From two fsh. That parasite are isolated from the muscle of abdomen and abdomen cavity for frst time in the common carp (Cyprinus carpio) in iran. We know Anisakis parasite one of the most important disease human can be infected from sea aquatic animal and from fsh. If the human have ate the fsh are not complicity cooking, the parasite can translate to human body and live in G.I system and make a bad illness. The cyprindeh family is the one of cheeped and widespread fsh are growing in Iran and people are used in our foot. This survey showed the some common carp (Cyprinus carpio) fsh of Aras dam are infected with zoonotic Anisakis sp. parasite and for frst time report of common carp (Cyprinus carpio) fsh in Aras dam of west Azerbaijan.
