BACKGROUND: This study aimed to solve the problems faced with the previous model of inflammatory tooth pain in rats. METHODS: After cutting 2 mm of the distal extremities, the polyethylene crowns were placed on the mandibular incisors. In contrast to the original model, we used flow composite instead of wire in order to maximize the retention of crowns. Different concentrations of capsaicin (10...

cisplatin is an effective chemotherapeutics against a wide range of cancers. however, it causes significant nausea and vomiting which limit its usefulness. in the present study, the effects of methanolic root extract of pluchea lanceolata (dc.) c. b. clarke , asteraceae ( mpl ) was investigated against cisplatin-induced nausea using a rat pica model. in rat pica model, rats react to cisplatin (...

objectives: crocin, a constituent of saffron and yellow gardenia, possesses anti-nociceptive effects. in the present study, we investigated the effects of intra-fourth ventricle injection of crocin in a rat model of orofacial pain. the contribution of opioid system was assessed using intra-fourth ventricle injection of naloxone, an opioid receptor antagonist. materials and methods: a guide cann...

ignoring two main characteristics of the concentration-response data, correlation between observations and presence of outliers, may lead to misleading results. therefore the special method should be considered. in this paper in to examine the effect of phenylephrine in rat corpus cavernosum, outlier robust nonlinear mixed estimation is used. in this study, eight different doses of phenylephrin...

objective(s): the effects of curcuma longa (c. longa) and curcumin on total and differential wbc count and oxidant, antioxidant biomarkers, in rat model of asthma were evaluated. materials and methods: total and differential wbc count in the blood, no2, no3, mda, sod, cat and thiol levels in serum were examined in control, asthma, asthmatic rats treated with c. longa (0.75, 1.50, and 3.00 mg/ml...

Hesperetin (Hst) is a well-known bioflavonoid, has low bioavailability. Hesperetin nanoparticles (Nano-Hst) enhance its bioavailability. Nano-Hst were not explored for their potential therapeutic activities in Alzheimer’s disease (AD). Hence, the present study was performed to evaluate the protective effect of Nano-Hst in comparison to free Hesperetin on against intracerebroventricular in...

the main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. pellet cores of budesonide were prepared by extrusion / spheronization technique. pectin, in different ratios was combined with eudragit rs30d, eudragit ne30d or surelease to produce film coating. the dissolution profiles of pectin coated pellets were investigated in ph of 1.2 (2 ...
