ZA Zakaria,G Hanan Kumar,Siti NH Mohd Zaid,Marwiza A Ghani,G Hanan Kumar,Siti NH Mohd Zaid,MH Hassan,Nurul AMN Hazalin,Mahirah M Khamis,G Rathna Devi,MR Sulaiman 경희대학교 융합한의과학연구소 2007 Oriental Pharmacy and Experimental Medicine Vol.7 No.1
The present study was carried out to elucidate the potential of Muntingia (M.) calabura leaves chloroform extract (MCCE) as antinociceptive, anti-inflammatory and antipyretic agents using various animal models. The dried powdered leaves of M. calabura (20 g) were soaked in chloroform for 72 h and the supernatant obtained was then evaporated to dryness. The crude dried extract (0.912 g), dissolved in dimethyl sulfoxide (1 : 20; w/v) and considered as a stock solution (100% concentration/strength), was then diluted to the concentrations of 10 and 50% and used together in all experimental models. The MCCE was found to show significant (P < 0.05) antinociceptive and antipyretic activities, but less remarkable anti-inflammatory activity. Only the antinociceptive activity of MCCE measured using the abdominal constriction test and in the first phase of the formalin test occurred in a concentration-dependent manner. The anti-inflammatory activity of 50 and 100% concentrations MCCE was observed only at the range of time interval of 60 - 120 and 60 min, respectively. Based on the results, we conclude that the M. calabura leaves chloroform extract possessed remarkable antinociceptive and antipyretic, but less effective anti-inflammatory, activities and thus justifies the Peruvian folklore claims of its medicinal values.

Antinociceptive profile of the ethanol extract of andrographis paniculata in mice

The present study was conducted to evaluate the analgesic activity of ethanol extract of Andrographis paniculata (AP) in mice. The analgesic investigations were carried out using the acetic acid-induced abdominal writhing and the hot-plate tests. It was demonstrated that intraperitoneal (i.p.) administration of the extract at a dose of 30, 100, 300, 500 mg/kg, produced significant inhibition of abdominal constriction induced with 0.6% (v/v) acetic acid in dosedependent manner. It also demonstrated that the extract produced significant dose-dependent increase in the time of latency to a discomfort reaction in the hot-plate model. In addition, the analgesic effect of the ethanolic extract of AP was significantly reversed by a non-specific opioid receptor antagonist, naloxone. These results indicate that AP has an analgesic effect that was mediated through opioid receptors.

Analgesic activity of three Channa spp. fish extracts
Solihah, MH,Israf, DA,Zuraini, A,Arifah, AK,Zakaria, MS,Zakaria, ZA,Sulaiman, MR,Jais, AM Mat,Somchit, N Kyung Hee Oriental Medicine Research Center 2006 Oriental pharmacy and experimental medicine Vol.6 No.4
In the present study, three Malaysian Channa spp. fish Channa striatus, Channa micropeltes and Channa lucius were assessed for their analgesic activity. Distilled water and mixture of chloroform: methanol were used for extraction. The analgesic or antinociceptive activity was investigated by abdominal writhing and hot plate test. The water extract of Channa striatus and the chloroform: methanol extract Channa lucius produced potent antinociceptive effect when assessed with the abdominal writhing test. The activity was compared to morphine where the activity of the extracts was less potent than the opioid. In the hote plate test, water extract of Channa striatus revealed significant activity and chloroform:methanol extract of Channa micropeltes had moderate activity. However, these activities were statistically lower than morphine. Collectively, this study also showed that Channa striatus extract was more potent analgesic agent when compared to the other closely related snakehead Channa micropeltes and Channa lucius.
