Introduction: Several studies have reported the involvement of age-related changes in the development of neuropathic pain behaviors. However, limited data are available on the role of age in establishing and maintaining chronic neuropathic pain after peripheral nerve injury. Methods: In the present study, we examined age-related neuropathic behavior among rats in 4 age groups: pups (4 weeks old...

The density of sodium channels was measured in growing and mature axons of the olfactory nerve of the bullfrog, using as a probe the drug saxitoxin (STX). The toxin binds to control nerves from adult animals in a saturable manner with a dissociation constant of approximately 23 nM at 4 degrees C and a capacity of 72 fmol/mg wet weight, equivalent to about five sites per square micrometer of axo...

The purpose of this study was to compare the effects of rat colostrum and mature milk on newborn rat gastrointestinal growth under conditions that controlled the possible confounding effects of energy intake and mode of feeding. Newborn Sprague-Dawley rat pups were tubefed equicaloric amounts of rat colostrum or mature rat milk for 40 h before they were killed. Compared to littermates that were...

The methanolic extracts of the frontal and mature leaves of Tectona grandis were comparatively evaluated for their analgesic and anti inflammatory activity. The analgesic and anti inflammatory activities were evaluated using the Eddy’s hot plate and Carrageenan induced paw edema models in rats respectively. The results of the analgesic activity have revealed that the frontal leaves and the matu...

cobitis faridpaki cobitis faridpaki (mousavi-sabet, vasil'eva, vatandoust and vasil'ev, 2011) is found in streams of the siahrud river in the southeastern caspian sea basin, and this is the first report on reproductive parameters of the newly described endemic loach. reproductive conditions are key parameters of fish populations, and their assessment is very important for endemic fishes. to stu...

In connection with a recent study on human milk fat (1.) an opportunity was afforded to measure qualitatively and quantitatively the fatty acid distribution in the fat from human milk collected during the first 3 days of lactation. Some differences in composition were observed ,for these colostrum samples when they were compared with mature human milk fat. It was considered desirable therefore ...
