BACKGROUND & OBJECTIVES Antidepressants are being used as analgesics for various pain related disorders like neuropathic and non neuropathic pain. Although their analgesic activity is well recognized but anti-inflammatory potential of antidepressants is still inconclusive. Since the antidepressants are used for longer duration, it becomes important to elucidate effect of anti-depressants on blo...

BACKGROUND Tissue damage may produce hyperalgesia, allodynia, and persistent pain. The authors recently reported that fentanyl elicits analgesia but also activates N-methyl-D-aspartate-dependent pain facilitatory processes opposing analgesia. In nonsuffering rats, this leads to a long-lasting enhancement in pain sensitivity. The current study assessed whether fentanyl could amplify carrageenan-...

BACKGROUND Peripheral tissue injury causes a migration of opioid peptide-containing immune cells to the inflamed site. The subsequent release and action of these peptides on opioid receptors localized on peripheral sensory nerve terminals causes endogenous analgesia. The spinal application of opioid drugs blocks the transmission of nociceptive information from peripheral injury. This study inve...

INTRODUCTION Fluoxetine is an antidepressant that has anti-inflammatory and antihyperalgesic effects in experimental models of pain and inflammation. The AIM of the present study was to determine the role of 5-HT2 receptors in the mechanism of anti-inflammatory and antihyperalgesic action of fluoxetine after single and repeated administration of the drug. MATERIALS AND METHODS 40 male Wistar ...

Introduction Proportional assist ventilation (PAV+) is a partial ventilatory support mode delivering airway pressure (Paw) in proportion to patient effort, enhancing patient-ventilator interactions. The ventilator estimates muscular pressure by using the respiratory system equation of motion with the instantaneous volume (V) and flow (V ́) and the automatically calculated compliance and resistan...

The threshold hydrostatic pressure necessary to produce pulmonary edema may be lowered by a decrease in plasma colloid oncotic pressure (COP) or an increase in capillary permeability. Sepsis is thought to increase capillary permeability. The object of this report was to assess the effect of sepsis on threshold hydrostatic pressure. In five adult male baboons a Foley catheter was inserted into t...

Plasma-activated water (PAW) is that has been treated with atmospheric pressure plasma. Due to the presence of reactive oxygen and nitrogen species (RONS), PAW can be used in various applications such as (1) surface disinfection food decontamination, (2) enhancement seed germination, (3) cooling nucleate boiling regime. Briefly, for disinfection, induce oxidative stress on microbes; trigger ger...

the novel bicyclo thieno 1, 2, 3-triazines (btt) namely btt-1, btt-2, btt-3 and btt-4 were evaluated for analgesic anti-inflammatory and antiarthritic activity. analgesic and anti-inflammatory activity was evaluated using hot plate test , formalin induced paw licking test and formalin induced paw edema test respectively, complete fruend’s adjuvant (cfa) induced arthritis model was used for anti...

INTRODUCTION Neuropathic pain is defined as pain arising as a direct consequence of a lesion or disease affecting the somatosensory system and is common after surgery. Neuropathic pain can persist without an obvious injury. In this study we aim to validate a murine chronic constriction injury model as a model for neuropathic pain research and determine if silk or catgut ligatures induced most s...

Many studies indicate that blood pressure control systems can attenuate pain (hypoalgesia) of short duration; however, we recently found exaggerated nociceptive responses (hyperalgesia) of persistent duration in the spontaneously hypertensive rat (SHR). Here, we used SHR, Dahl Salt-Sensitive (SS), and normotensive control rats to evaluate the contribution of sustained elevations in arterial pre...
