effects of insulin (1, 2 and 3 iu/kg, i.p.), morphine (5mg/kg, i.p.), naloxone (5mg/kg, s.c.), insulin before morphine and after naloxone were studied in the formalin test of mice. formalin test was induced by intraplantar injection of formalin (20m, 5%). morphine alone and insulin with morphine decreased the first phase (0-5 min) of pain. naloxone increased the interphase (6-20 min) of nicicep...
Animal models are used to research the mechanisms of pain and to mimic human pain. The purpose of this study was to determine the degree of interaction between dexketoprofen and dexibuprofen, by isobolographic analysis using the formalin orofacial assay in mice. This assay presents two-phase time course: an early short-lasting, phase I, starting immediately after the formalin injection producin...
This study investigated the effect of bergamot essential oil (BEO) or linalool, a major volatile component of BEO, on the nociceptive response to formalin. Plantar subcutaneous injection of BEO or linalool into the ipsilateral hindpaw reduced both the first and late phases of the formalin-induced licking and biting responses in mice. Plantar subcutaneous injection of BEO or linalool into the co...
abstract: introduction & objective: ferula gummosa boiss (apiaceae) is a perennial plant native to iran and afghanistan. like many plants, this species contains active biological compounds including monoterpenes, alfa pinene and alkaloids which have been demonstrated in phytochemical analysis of different extract of this species. in iranian traditional medicine ferula gummosa has been used in i...
Numerous human and animal studies indirectly implicate neurons in the anterior cingulate cortex (ACC) in the encoding of the affective consequences of nociceptor stimulation. No causal evidence, however, has been put forth linking the ACC specifically to this function. Using a rodent pain assay that combines the hind-paw formalin model with the place-conditioning paradigm, we measured a learned...
Formalin is a hazardous chemical that needs cautious handling and special storage. Owing to its disinfectant and fixative (i.e. for preserving pathologic tissue specimens in histopathology) properties, it is widely used in dentistry. Although, the terms formaldehyde and formalin are often confused as being identical, these are different as to the concentrations of the primary component i.e. for...
BACKGROUND Pain plays roles in both the nervous system and immune system. Changes in the neuroendocrine pathway under pain conditions give rise to sympathetic outflow with increased plasma catecholamines and activate immune reactions. Dexmedetomidine exerts sedative, analgesic, and anesthetic-sparing effects and is known to diminish pro-inflammatory processes by central sympatholytic effects. T...
A study was designed to compare the effectiveness and time efficiency of three collection-preservation methods individually and grouped to form systems. Employees and members of their families of an agricultural grower in Hillsborough County, Fla., provided all fecal specimens used in the study. The 160 individuals participating were members of 64 families and represented a cross section of all...
In vitro mutation artifacts after formalin fixation and error prone translesion synthesis during PCR
BACKGROUND: Clinical specimens are routinely fixed in 10% buffered formalin and paraffin embedded. Although DNA is commonly extracted from fixed tissues and amplified by PCR, the effects of formalin fixation are relatively unknown. Formalin fixation is known to impair PCR, presumably through damage that blocks polymerase elongation, but an insidious possibility is error prone translesion synthe...
