introduction: mineral trioxide aggregate (mta) is an endodontic material with different clinical applications e.g. root-end filling, pulp capping and perforation repair. it has been reported to possess antimicrobial and antifungal activities. the aim of this study was to examine the effect of white mta on formalin-induced hyperalgesia in a rat with inflammatory pain. materials and methods: inf...
Large repositories of well characterized RNAlater preserved samples and formalin-fixed, paraffin-embedded samples have been generated worldwide. However, the impact on the proteome of the preservation methods remain poorly described. Therefore, we analyzed the impact on the proteome of preserving samples in RNAlater, and by formalin-fixation, paraffin-embedding on human soft tissue, using direc...
In the present study, effects of intracerebroventricular (icv) administration of histamine, mepyramine (H1-receptor antagonist) and famotidine (H2-receptor antagonist) have been investigated on the formalin test in rats. Subcutaneous injection of formalin (50 microl, 1%) into the ventral surface of the left hind paw produced a marked biphasic pain response (first phase: 0-5 min and second phase...
BACKGROUND We conducted this study to investigate whether formalin fixation is associated with the shrinkage of head and neck cancer specimens. METHODS Patients scheduled to undergo operation were eligible for enrollment. Fresh specimens were measured immediately in the operating room, and the measurements were repeated after formalin fixation. RESULTS A total of 100 specimens were collecte...
the effects of formalin as a peripheral noxious stimulus on the activity of lateral paragigantocellularis nucleus (lpgi) neurons were examined. spontaneous activity oflpgi neurons was recorded after confirmation of their responsiveness to acute pain, and thereafter formalin (50 µl, 2.5%) was injected in the contralateral hindpaw. the response of the lpgi neurons was monitored for 60 min. a biph...
Characterization of Nociceptive Behaviors Induced by Formalin in the Glabrous and Hairy Skin of Rats
Introduction: Glabrous skin and hairy skin are innervated by different types of noxious fibers. However, the different nociceptive behaviors induced by formalin, a commonly used model of acute inflammatory pain, have not yet been systematically examined in the glabrous and hairy skin. Methods: In this study, we compared nociceptive behaviors induced by formalin injections (2%, 4%, and 8%) into...
Gossypin is a bioflavonoid isolated from Hibiscus Vitifolus Linn. The antinociception activity of gossypin has been studied in comparison with the standard antinociception agent, morphine, against the experimental model of tonic continuous pain produced by formalin. Formalin (0.1ml of 1% solution) was injected under the plantar surface of right hind paw of mice and the time an animal spent in l...
Evaluation of mRNA Expression Calcitonin Gene-Dependent Peptide (CGRP) and Rat (rCT) in the Periaqueductal Gray Area (PAG) Diabetic Rats Formalin Test
Background: Salted fish is one of the food ingredients that often added with formalin to extend shelf life product, although a preservative cannot be used in food. Indonesian traditional markets still sell salted formalin. Objective: This study aims analyze content Kedungprahu Traditional Market. Method: research method was descriptive using qualitative analysis which includes observing physica...
Anti-inflammatory effects of acetonic and methanolic extracts of aerial parts of Stachys byzanthina were investigated in this study. For assessment of anti-inflammatory properties, two well-characterized inflammatory models, formalin test and carrageenan-induced paw edema were used. In the former, the recording of the early phase started immediately after formalin injection and lasted for 10 mi...
