Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

in this study, considering the normal ingredients in guinea pig's milk, by using cow milk, mixture of vitamins and minerals, a milk substitute was prepared and sterilized by autoclaving and filtration methods. in food analysis of produced milk, the important substances values, such as protein, fat and ash, were suitable. milk substitute was fed to four groups of newborn's guinea pigs that we...

there is documented evidence that infection in laboratory animals can often influence the outcome of experiments. all infections, apparent or inapparent, are likely to increase biological variability. as a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 ) and 105 guinea pigs (f...

      Flavonoids could serve as potent inhibitors of xanthine oxidase (XO). In the present study, the effects of Ruta graveolens L. extract and its major isolated flavonoids, quercetin and rutin, on guinea pig liver XO have been investigated. The inhibitory effects of R. graveolens, quercetin and its glycoside form, rutin, were assayed spectrophotometrically. R. graveolens...

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 guinea ...

Objective(s): To study the c-Kit expression in the gallbladder of cholesterol lithogenic guinea pig model and the effect of Artemisia capillaris Thunb on interstitial cells of Cajal (ICCs). Materials and Methods:A total of 45 guinea pigs were randomly assigned into three groups: the control group (guinea pigs fed a standard diet, normal group); the model group (guinea pigs fed a cholesterol gal...

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...
