On some toxinological aspects of the starfish Stellaster equestris (Retzius, 1805) J. Venom. Anim. Toxins incl. Trop. Dis.
Kanagarajan,U; Bragadeeswaran,S; Venkateshvaran,K.
Whole-body extracts in methanol were obtained from the starfish Stellaster equestris. The crude toxin was fractionated stepwise using diethylaminoethyl (DEAE) cellulose column chromatography. The crude toxin was lethal to male albino mice at a dose of 1.00 mL (containing 531.0 µg/mL protein) when injected intraperitoneally (IP) but the toxicity was abolished in all cases except one upon fractionation. The crude toxin and all the adsorbed fractions exhibited potent hemolytic activity on chicken, goat and human blood. However, group B human erythrocytes were resistant to lysis by all fractions and group O by most of the fractions. Paw edema in mice was caused by the crude toxin and all fractions. Pheniramine maleate and piroxicam blocked the toxicity when...

Pharmacological study of anti-allergic activity of Syzygium cumini (L.) Skeels BJMBR
Brito,F.A.; Lima,L.A.; Ramos,M.F.S.; Nakamura,M.J.; Cavalher-Machado,S.C.; Siani,A.C.; Henriques,M.G.M.O.; Sampaio,A.L.F..
Myrtaceae is a plant family widely used in folk medicine and Syzygium and Eugenia are among the most important genera. We investigated the anti-allergic properties of an aqueous leaf extract of Syzygium cumini (L.) Skeels (SC). HPLC analysis revealed that hydrolyzable tannins and flavonoids are the major components of the extract. Oral administration of SC (25-100 mg/kg) in Swiss mice (20-25 g; N = 7/group) inhibited paw edema induced by compound 48/80 (50% inhibition, 100 mg/kg; P <= 0.05) and, to a lesser extent, the allergic paw edema (23% inhibition, 100 mg/kg; P <= 0.05). SC treatment also inhibited the edema induced by histamine (58% inhibition; P <= 0.05) and 5-HT (52% inhibition; P <= 0.05) but had no effect on platelet-aggregating...
