in the present study the effect of the locally produced genetic adjuvant of ginea pig specific cpg-motif-containing oligodeoxynucleotide (cpg-odn) in an inactivated fmd virus vaccine was evaluated. boosting the ginea pigs with fmd vaccine along with cpg-odn adjuvant produced relatively higher ratio (5-fold) of fmdv-specific igg2a / igg1 than those vaccinated in the absence of cpg-odn. the neutr...

sodium valproate (sv), an antiepileptic drug has several mechanism of action. it inhibits voltage sensitive na+ channels and reduces intracellular na accumulation. these actions are similar to that of both phenytoin and carbamazepine. we have investigated the direct cardiac action of sv and its effects on ouabain-induced arrhythmia in isolated guinea-pig atria. the guinea-pig atrium was dissect...

Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

Background: Fibroblast cell lines have different application in biological research including nuclear transfer in cloning, feeder layer of embryonic stem cells, wound healing research and tissue engineering. The objective of the present study was to determine the proper pregnancy age for collecting and culturing guinea pig fetal fibroblast. Materials and Methods: Guinea pig fetuses were collect...

Cu and Zn are known to be abundant in swine feces; hence, concentrations of these metals need lowered before feces applied land order prevent potential environmental problems. The main objective this study was develop an appropriate chemical process remove from using acid extractions. removal efficiencies decreased the H2SO4 > HNO3 organic acids (citric oxalic acids). Owing highest by H2SO4,...

background: this study was designed to investigate the efficacy of pentoxifylline (ptx) in the treatment of irradiated wounds. materials and methods: ten female pigs of the large white strain were used in these investigations. six skin fields, 4 * 4 cm and separated from each other by 4 cm, were marked out on each flank and those on left flank were irradiated with 18gy single dose of 250 kv x-r...

background : animal models have been proven useful in elucidating the details of interaction between pathogenic bacteria and their human hosts, in addition to assessing the efficacy of therapeutic compounds and vaccines. in this study, we investigate the colonization of helicobacter pylori ( h. pylori ) in experimentally-infected guinea pigs over a six-month period. materials and methods: a bac...

Alternative methods to the utilization of laboratory animal blood and its by-products are particularly attractive, especially regarding hamsters due to their small size and difficulties in obtaining serial blood samples. Steroid hormone metabolite quantification in feces, widely used in studies of free-ranging or intractable animals, is a non-invasive, non-stressor, economical, and animal savin...

Previous studies indicate that Matricaria chamomilla (MC), a folk remedy plant, is very useful in the treatment of spasmogenic bowel diseases but the way of its action is not clear. For this purpose, we studied the effect of MC extract on the electrically activation in Guinea-Pig ileum in an invitro model. We used guinea pig in this study. After of kill, we brouhght out a piece of ileum and fix...

Protein content and ion composition of host blood and feces from blood-fed adult cat fleas, Ctenocephalides felis (Bouché), were examined. Total fecal protein differed slightly from host blood indicating that there was little digestion of host blood by adult fleas. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels of host blood and flea feces also revealed little digestion, as evid...
