Ischemia-reperfusion (I/R) injury is a primary cause of poor outcomes following ischemic cardiovascular events. We tested whether acute hot water immersion protects against forearm vascular I/R. Ten (5 male, 5 female) young (23 ± 2 yr), healthy subjects participated in two trials in random order 7-21 days apart, involving: 1) 60 min of seated rest (control), or 2) 60 min of immersion in 40.5°C ...

OBJECTIVE To investigate the effectiveness of hot water immersion for relieving the pain of major box jellyfish (Chironex fleckeri) stings.Design, interventions: Open label, randomised controlled trial comparing the effects of hot water immersion (45°C) and icepacks.Setting, participants: 42 patients with suspected C. fleckeri stings treated in the emergency department of the Royal Darwin Hospi...

We determined whether immersion in 49 degrees C water for 20 min, a quarantine treatment developed for disinfestation of fruit flies in lychee, Litchi chinensis Sonn., and longan, Dimocarpus longan (Lourd.) Steud., exported from Hawaii, would also disinfest fruit of two species of Cryptophlebia. The pattern of tolerance to heat in Cryptophlebia illepida (Butler) was generally eggs < neonates < ...

BACKGROUND Various parts of Pandanus foetidus Roxb. are used as traditional medicines. However, scientific reports concerning the effect of this plant on central nervous system (CNS) depression and analgesia are unavailable. This study investigated the CNS depressant and antinociceptive effects of Pandanus foetidus leaf extracts in a rodent model. METHODS The sedative and anxiolytic activitie...

Background. Acrylic resins used in restorative dentistry are the most popular denture base material, because they have good optical properties and small solubility in body fluids. However their mechanical properties are limited and therefore acrylic resins require different methods of reinforcement one of which can be application of different kinds of fibers. Objectives. To investigate the effe...

BACKGROUND People with hypertension are commonly warned to check with a physician before using a hot tub, but there is little literature on which to base this advice. We compared symptoms, heart rate, and systolic and diastolic blood pressure in response to 10 minutes of hot-tub immersion in a group of patients with treated hypertension and in a control group normotensive subjects. METHODS We...

The antinociceptive effect of Elaeagnus angustifolia fruits was studied in mice. The antinociceptive effect of ethanolic and boiling water extracts was studied using two thermal stimuli, the hot-plate and tail-flick tests. The intraperitoneal and oral administration of the ethanolic extract of seed 0.75-7.00 g/kg), but not pericarp and medulla had significant antinociceptive activity in the...

The sedative and analgesic potential of Urena sinuata L. was investigated for the first time in this study. The crude methanol extract of Urena sinuata L. leaves was evaluated for its central nervous system (CNS) depressant effect using rodent behavioral models. Methanol extract of Urena sinuata at a dose of 400 mg/kg body weight, displayed a suppressive effect on motor activity, exploratory be...

This study investigated the antinociceptive mechanisms of khat extract (100, 200, and 400 mg/kg, i.p.) in four pain models: two thermic (hot plate, tail-flick) and two chemical (acetic acid, formalin) models. Male mice were pretreated intraperitoneally (i.p.) with the opioid receptor blocker naloxone (5 mg/kg), the cholinergic antagonist atropine (2 mg/kg), the selective α1 blocker prazosin (1 ...
