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...

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 extract showed moderate inh...

borrelia microtti and borrelia persica are two iranian strains of spirochetes whose vectors are ornithodorous tholozani and ornithodorous erraticus which are responsible for relapsing fever. bsk medium has been used for in vitro culture of other strains of borrelia, although the two mentioned strains could not be successfully cultured in it. we have modified bsk medium by using guinea pig and f...

Phosphor-in-glass (PiG) film is a promising luminescent material in high-brightness laser lighting for its advantages of high efficiency, outstanding color quality, and low-cost preparation, which must bear power (LP) density (LPD) simultaneously to enable high-luminance light. Herein, spot associated high-saturation PiG was proposed transmissive reflective lighting. Two types films were prepar...

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...
