The present study characterized renewal of sucrose-seeking behavior in rats (Experiment 1). The role of the dopamine subtype-2 (D(2)) receptors in mediating renewal of sucrose-seeking behavior also was examined (Experiment 2). Rats were trained to respond for sucrose pellets (45mg each) on a fixed-ratio 25 (Experiments 1 and 2) schedule of reinforcement in Context A. Following acquisition, rats...

Diets high in sucrose or fructose have been shown by others to induce a modest elevation of blood pressure in rats. The present experiments were conducted to determine whether the sucrose-induced increase of blood pressure is dependent on the intake of sodium chloride. Four groups of Sprague-Dawley rats were studied: 1) a group maintained on a low salt diet and distilled water (0.45% sodium chl...

the objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in holstein dairy cows. four multiparous holstein dairy cows (665 ± 25 kg bw, 170 ± 7.0 dim and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 latin square design with 28-d periods. corn starch and sucro...

Although fish oil supplementation may prevent the onset of diet-induced insulin resistance in rats, it appears to worsen glycemic control in humans with existing insulin resistance. In the present study, the euglycemic, hyperinsulinemic (4× basal) clamp technique with [3-3H]glucose and 2-deoxy-[1-14C]glucose was used to directly compare the ability of fish oil to prevent and reverse sucrose-ind...

the aim of this investigation was to assess the effect of different antioxidants on the motility andmembrane integrity of the ram semen during storage at 5ºc for 0, 12, 24, 48 and 72 hrs after collection anddilution. a total of 57 ejaculates from 12 bakhtiary rams was collected by artificial vagina and were extended1 : 3 with egg yolk-citrate buffer, which was containing one of the following an...

background: cries of the newborn could be due to pain, thirst, hungry and fear from new environment. in our study we evaluated the effect of the sucrose drops on pacifying the children prior to a painful intervention or procedure with regards to the fasting condition of the children. methods: this triple blind clinical trial was conducted on 60 otherwise healthy children aged less than 1 year w...

ABSTRACT- Chrysanthemum (Dendranthema grandiflorum) is one of the most important ornamental plants used as cut flower, flowering pot plant and groundcover worldwide. In this research, the effects of preservative solutions containing thymol (75 and 125 mg -L), menthol (75 and 125 mg L-1) and eugenol (75 and 125 mg L-1) on the quality and vase-life of chrysanthemum cut flowers at 3±1ºC and 75-80%...

Posttrial administration of corticosterone was previously shown to enhance consummatory successive negative contrast (cSNC) in rats. The present series of experiments provides additional information that helps determine the boundaries of this effect. Posttrial corticosterone administration (1) enhances cSNC when rats experience a large downshift (32% to 4% sucrose), but not after a small downsh...
