BACKGROUND: Some anaesthetic agents exhibit an age-dependent analgesic effect, for example nitrous oxide, which is ineffective in newborn rats. We investigated whether a similar time dependency existed for the responses to the volatile anaesthetic isoflurane. METHODS: The analgesic and hypnotic properties of isoflurane at various ages was assessed using four cohorts of Fischer rats aged approximately 7, 16, and 28 days and adults (11-12 weeks old).

We developed a novel method to prepare nanocapsules. A solute often crystallizes when its solubility alters from one solvent to another, and its firstborn crystals are used as templates to prepare nanocapsules for the first time, which is called firstborn microcrystallization method. By using this method, the maximum diameter of the nanocapsules including artesunate is about 76 nm, and wrapping state is well.

Molecular Pain

BACKGROUND: Affections are thought to regulate pain perception through the descending pain inhibitory system in the central nervous system. In this study, we examined in mice the affective change by inhalation of the lemon oil, which is well used for aromatherapy, and the effect of lemon odor on pain sensation. We also examined the anterior cingulate cortex (ACC) and descending pain inhibitory system to such regulation of pain. RESULTS: In the elevated plus maze, the time spent in the open arms was increased by inhalation of lemon oil.

This study confirmed the oral anti-inflammatory, analgesic and antihistamine properties of mature fresh leaves (MFL) of Vitex negundo L. (Verbenaceae) claimed in the Ayurveda medicine by orally treating a water extract of the leaves to rats. The early phase (2h) of carrageenan-induced rat paw oedema was significantly (P<0.01) suppressed in an inversely does-dependent (r(2)=1, P<0.01) manner by MFL. The EC(50) was 2g/kg of MFL. In the formaldehyde-induced rat paw oedema test, the 2.5 and 5g/kg leaves significantly (P<0.05) suppressed the inflammation on days 4-6 of the test.

The antiatherogenic effect of a herbal formulation, Caps HT2, was evaluated as antioxidant, anticoagulant, platelet antiaggregatory, lipoprotein lipase releasing, anti-inflammatory and hypolipidaemic activity in rats. The formulation contained the methanolic extracts of selected parts of plants, Commiphora mukul, Allium sativum, Plumbago indica, Semecarpus anacardium, Hemidesmus indicus, Terminalia arjuna, Tinospora cordifolia, Withania somnifera and Ocimum sanctum.

ETHNOPHARMACOLOGICAL RELEVANCE: Mesua ferrea Linn. (Cluciaseae), Cobra's saffron, is named after the heaviness of its timber and is cultivated in tropical climates for its form, foliage, and fragrant flowers. It is prescribed in the Ayurvedic literature for the treatment of pain, inflammation, and rheumatic conditions. OBJECTIVE: In present investigation, activity of Mesua ferrea and its evaluation in the formaldehyde and Complete Freund's Adjuvant (CFA)-induced arthritis in rats is reported.

AIM OF THE STUDY: Emilia sonchifolia (L.) DC. (Asteraceae) is a medicinal plant traditionally used in Brazilian folk medicine to treat asthma, fever, cuts, wounds and rheumatism. This study was conducted to establish the antinociceptive properties of hydroethanolic extract from aerial parts of Emilia sonchifolia in mice using chemical and thermal models of nociception.

Chantaleela recipe is indicated for relieving fever in Thai traditional folk medicine. In the present study, Chantaleela recipe was investigated for anti-inflammatory, analgesic, antipyretic and anti-ulcerogenic activities. In preliminary investigation Chantaleela recipe was found to exert an inhibitory activity on the acute phase of inflammation as seen in ethyl phenylpropiolate-induced ear edema as well as in carrageenan-induced hind paw edema in rats. The results suggest that the anti-inflammatory activity of Chantaleela recipe may be due to an inhibition via cyclooxygenase pathway.

Aconiti Brachypodi Radix, belonging to the genus of Aconitum (Family Ranunculaceae), are used clinically as anti-rheumatic, anti-inflammatory and anti-nociceptive in traditional medicine of China. However, its mechanism and influence on nociceptive threshold are unknown and need further investigation. The analgesic effects of ethanolic extract of Aconiti Brachypodi Radix (EABR) were thus studied in vivo and in vitro. Three pain models in mice were used to assess the effect of EABR on nociceptive threshold.
