this survey was aimed at detecting histological and histometrical changes of common carp ovaries in khouzestan province climate conditions. the goal was to determine the ovarian status in the breeding period of the reproductive cycle. ovaries of 49 common carp brooders were collected from april to october, 2010. the samples were taken from the anterior, median and posterior portions. 5-6µ secti...

abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...

background and objective: the fallopian tube plays an essential role in tubal transportof both gametes and embryos and successful pregnancy. we assessed the histomorphological effect of smoking on the fallopian tubes in rats, in this study. patients and methods: twelve female rats were divided to two groups as subjects (n=7) and controls (n=5). they have been exposed to smoke four times daily f...

There are numerous reports in the literature using animal models of osteomyelitis for investigating pathogenesis, diagnosis, and treatment of bone infections. Rabbits, rats, and dogs are commonly used animals, and, less frequently, chickens, guinea pigs, miniature pigs, goats, and sheep. Commonly used bones for creating local osteomyelitis include tibia, femur, and radius, and, less frequently,...

Optimization of intratracheal instillation is necessary to establish an ideal animal model of acute lung injury (ALI) in order to further reveal the cellular and molecular pathogenesis of ALI. It is possible that instilling air from a prefilled syringe may promote the delivery of reagents into the alveolar spaces, resulting in different pulmonary responses. In the present study, the influence o...

introduction: parasitic diseases could be one of the common problems of human society in any time in every place. the animals can passed this infection to human as zoonotic disease. cats are one of the most important animals that living and eating long with human in society. therefore feline parasitic zoonosis is threatened human health and cause death and serious disease. for the reason, the p...

carbosulfan (2,3-dihydro-2,2dimethyl-7-benzofuronyl [(dibutyl amino) thio] methyl] a carbamate insecticide and acaricide was administered orally at an effective dose of 48 mg/kg/day to albino mice for 5, 10, 20 and 30 days .control mice received similar quantities of olive oil. daily body weights were recorded and mice were sacrificed after 24 hours after the terminal exposure. the histologic e...

Semecarpus anacardium (SA) popularly known as marking nut has been used in folklore for the treatment of a wide range of diseases. Extracts (hydro-alcoholic and oil) of SA were evaluated for their anticancer activity against Ehrlich ascites carcinoma (EAC) in nude mice. Extracts and standard drug (cyclophosphamide) at a dose of 20 mg/kg body weight were administered orally and continued for 10 ...

Space flight studies using the Animal Enclosure Module (AEM) make it possible to investigate the role of microgravity on animal physiology and behavior. In this study, we compared the health and well-being of mice housed at different densities in AEM simulators (AEMS), to vivarium shoebox (control) cages (VSBC). A stress assessment battery (SAB) of measures was developed to evaluate mouse healt...
