Anti-inflammatory effect of Acacia visco extracts in animal models.

The aqueous and organic extracts of Acacia visco Lor. Ap Griseb (Fabaceae) were tested for anti-inflammatory activity in experimental models in rat. Besides, the free-radical scavenging capacity of extracts from A.

Anti-ulcerogenic and anti-inflammatory activity of the methanolic extract of Larrea divaricata Cav. in rat.

Larrea divaricata Cav. (Zygophyllaceae) is used in popular medicine as anti-inflammatory and anti-rheumatic drug, containing higher amounts of nordihydroguaiaretic acid, a well-known free radical scavenger. Here we describe the gastric anti-ulcerogenic effect of the methanolic extract of Larrea divaricata (LdME) leaves in rat, using absolute ethanol and HCl 0.

Different effects of melatonin on experimental granulomatous inflammation.

Several experiments have detected that melatonin exerts a marked influence on the inflammatory process. In the present study we evaluated the effect of exogenous melatonin on the experimental granulomatous tissues in rat. Our data show that subcutaneous administration of different doses of melatonin given daily during 6 days at 9:00 h do not have significant action on the granuloma weight.

Comparative study of flavonoids in experimental models of inflammation.

The anti-inflammatory activities of flavonols (quercetin, rutin and morin) and flavanones (hesperetin and hesperidin) were investigated in animal models of acute and chronic inflammation. Rutin was only effective in the chronic process, principally in adjuvant arthritis. On neurogenic inflammation induced by xylene, only the flavanones were effective; besides, these compounds were the most effective on subchronic process.
