Antiinflammatory effects of the fruit juice of Ecballium elaterium on edemas in mice

The anti-inflammatory activities of the fruit juice of Ecballium elaterium (Cucurbitaceae) and its triterpenoid constituent, cucurbitacin B, were tested in mice against serotonin- and bradykinin-induced edemas. Both showed a dose-dependent and significant inhibition of edema. Cucurbitacin B content of fruit juice was determined to 2.48% by HPLC.     

Analgesic and antipyretic effects of Myrica salicifolia (Myricaceae)

Myrica salicifolia Hoechst (Myricaceae) root extract was found to have analgesic activity in mice. In rats there was antipyretic but no antiinflammatory activity.     

Analgesic and antipyretic properties of Euphorbia royleana latex

The ethyl acetate fraction (EA) from the residue of an 85% ethanol extract of the latex of Euphorbia royleana (Euphorbiaceae) was investigated for antipyretic and analgesic properties. The results showed a dose related peripheral analgesic effect. The fraction assayed exhibited a significant antipyretic effect in hyperthermic rats and rabbits. The oral LD₅₀ was more than 2 g/kg in rats and mice. © 1997 John Wiley & Sons, Ltd.     

Analgesic,antipyretic and antiinflammatory effects of Achillea ageratum

The aqueous and methanol extracts of Achillea ageratum L. (Asteraceae) have been evaluated for analgesic, antipyretic and antiinflammatory properties in mice and rats in several experimental models. The aqueous extract exhibited significant activity in the analgesic and antiinflammatory assays but was unable to reduce hyperthermia. Moreover, the methanol extract exerted effects in three pharmacological actions. The phytochemical investigation of this latter extract revealed the presence of flavonic compounds: luteolin, quercetin and 7-O-β-luteolin. © 1997 John Wiley & Sons, Ltd.     

Pharmacological properties of Visnea mocanera L. f. extracts: Screening for analgesic,antipyretic, antiinflammatory and ulcerogenic activities in rodents

Different extracts of Visnea mocanera L. f. (Theaceae) were evaluated for analgesic, antipyretic, antiinflammatory and ulcerogenic properties in mice and rats. The acetone extract from the leaves and the syrup from the fruits exerted central analgesic properties, associated with significant but transient antiinflammatory effects on acute inflammatory processes. The acetone extract also possessed topical antiinflammatory effects. The extracts assayed did not display antipyretic and ulcerogenic activity. Sub-acute toxicological experiments indicated a very low toxicity in mice.     

Analgesic, antipyretic and Ulcerogenic properties of an indigenous formulation--Kalpaamruthaa

A modified indigenous Siddha formulation Kalpaamruthaa (KA), containing Semecarpus anacardium nut milk extract (SA), dried powder of Emblica officinalis (EO) fruit and honey was evaluated for its analgesic, antipyretic and Ulcerogenic properties. Both SA and KA, at a dose of 150 mg/kg b. wt were compared with the standard drug diclofenac sodium. KA exhibited an enhanced effect on all properties compared with that found with sole SA treatment, and is likely to be due to synergistic and additive interactions within the complex mixture of phytochemicals present in KA.

Analgesic and antiinflammatory properties of Scoparia dulcis L. Extracts and glutinol in rodents

The analgesic, antiinflammatory and antipyretic activities of the water (WE) and ethanolic (EE) extracts of Scoparia dulcis L. were tested in mice and rats. Both extracts (0.5 and 1 g/kg) p.o., prolonged the sleeping time induced by pentobarbital in mice, EE being more active than WE. Injections of EE (0.5–2 mg/kg i.v.) to anaesthetized rats induced a dose-related hypertension inhibited by alpha-blocker drugs; the hypertension was not obtained after oral treatment. EE (0.25-1 g/kg p.o.) but not WE, reduced writhings induced by acetic acid in mice. Glutinol (30 mg/kg p.o.), a major triterpene obtained from EE, produced the same effect. The tail flick response of mice was not influenced by either extract. EE (0.5 and 1 g/kg) and glutinol (30 mg/kg) p.o., reduced the paw oedema and pleurisy induced by carrageenin in rats, but only EE (1 g/kg) reduced the paw oedema induced by dextran or histamine. No effect of EE was detected on chronic inflammation induced by cotton pellets and in yeast-induced hyperthermia in rats. The results indicate that the extract of S. dulcis is endowed with analgesic effects probably related to the antiinflammatory activity of the plant. Those effects are related mainly to the presence of glutinol and flavonoids, which exert their action on the early phase of the acute inflammatory process.

目的 研究干姜乙醇提取物(干姜醇提物)的抗炎、解热、镇痛和体外抑菌作用。方法 采用小鼠耳壳肿胀法，伤寒、副伤寒甲乙三联菌苗导致家兔发热反应以及小鼠扭体法观察干姜醇提物的抗炎、解热、镇痛作用；采用平皿二倍稀释法测定干姜醇提物的最低抑菌浓度(MIC)。结果 干姜醇提物抑制二甲苯所致小鼠耳壳肿胀及醋酸所致小鼠扭体反应，并具有明显的抑制伤寒、副伤寒甲乙三联菌苗所致家兔发热反应作用；干姜醇提物对8株菌的MIC范围为13．5～432mg／mL。结论 干姜醇提物具有明显的抗炎、解热、镇痛及体外抑菌作用。     

Analgesic and hepatotoxic effects of Ononis spinosa L

The present study investigated the analgesic and hepatoprotective activities of a water extract of Ononis spinosa L. (OS) in mice. Analgesic activity was based on the pain thresholds measured with the tail-flick test before administration at 30, 90 and 150 min. The results were analysed with one-way variance analysis. The extract of Ononis spinosa showed analgesic activity equivalent to aspirin at 30 and 90 min and even higher than aspirin with the 50 mg/kg dose. At a dose of 100 mg/kg OS showed an analgesic effect equivalent to aspirin at all time points.The hepatoprotective influence of OS on carbon tetrachloride (CCl(4))-induced acute liver toxicity was also studied. The extract had no significant effect on the increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and bilirubin in CCl(4) treated animals (p > 0.05). Thus, the results reveal that the extract of OS had no hepatoprotective effect on CCl(4)-induced acute liver toxicity.

Analgesic and central depressor effects of the dichloromethanol extract from Schinus molle L.

The analgesic and central depressor effects of the dichloromethanol extract of Schinus molle L. were analysed in in vivo models. This extract showed low acute toxicity, CNS depressor activity and analgesic effect. Following further fractionation, the hexane/dichloromethane (75/25) fraction showed the most interesting results. Thus, this fraction caused a total inhibition of motor activity and significantly reduced the threshold of pain to chemical stimulus. © 1997 John Wiley & Sons, Ltd.

Pharmacological studies of the antiinflammatory profile of Mikania cordata (Burm) B. L. robinson root extract in rodents

The methanolic fraction of the root extract of Mikania cordata was found to possess an inhibitory effect on carrageenin and other mediator—induced oedema; there was a significant inhibition of protein exudation, an increase in peritoneal capillary permeability and leucocyte migration in inflammatory conditions. The extract significantly inhibited both cotton pellet and carrageenin—induced granuloma formation, was effective in experimentally induced arthritic conditions and turpentine—induced joint oedema. The extract also possessed inhibitory effects on sodium urate-induced experimental gout. A significant reduction of pyrexia was also found to occur when rats were treated with the extract. Thus it may be concluded that the methanolic fraction of M. cordata root extract possessed significant antiinflammatory effects in exudative, proliferative and chronic phases of inflammation and demonstrated an antipyretic activity.
