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...

The in vivo metabolism of 2,2',3,4,4',5',6-heptachlorobiphenyl (CB183) was studied in rats and guinea pigs. Similarly to the in vitro metabolism, 3'-hydroxy (OH)-CB183 and 5-OH-CB183, were found as major metabolites in the serum and the feces of both species (serum < feces). Phenobarbital (PB)-pretreatment of animals increased the production of both metabolites, whereas 3-methylcholanthrene (MC...

background: the study was targeted to report the appearance of coproantigens in feces and circulating antibodies in the serum of fasciola gigantica  experimentally infected rabbits. methods: copro hyper immune serum (his) and excretory-secretory hyper immune serum (es his) antigens were used in a sandwich elisa for the detection of f. gigantica antigens in feces of 12 rabbits experimentally inf...

The attraction response of Stomoxys calcitrans (L.) to its own feces was evaluated in a triple cage olfactometer. Both time- and concentration-response relationships were obtained for female S. calcitrans exposed to cellulose sponges impregnated with fresh fly feces or filter papers treated with chloroform:methanol extracts of fresh fly feces in 6-min tests. Attraction to feces collected on cel...

Outbred and inbred (Hartley strain) guinea pigs (GP) were inoculated intragastrically with pathogenic and nonpathogenic Treponema hyodysenteriae. GP 3 to 16 weeks old received T. hyodysenteriae after a fasting period of 36 to 72 h. Infected GP with pathogenic T. hyodysenteriae developed a diarrheal and/or depressive condition, with mucus but not blood in the feces. Of 88 GP, 40 had gross lesion...

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...

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...
