Major attention has been on dietary and medicinal phytochemicals that inhibit or reverse abnormal conditions caused by nociceptive inflammatory stimuli. Garcinia kola (Guttiferae) seed, known as "bitter kola", plays an important role in African ethno-medicine traditional hospitality like the treatment of inflammation, colds, bronchitis, bacterial, viral infections. A number useful have isolated from most prominent them is kolaviron (Garcinia bioflavonoid), which suggested to antinociceptive...

Methanol extract of Cola nitida (MECN) was evaluated for its anti-inflammatory and analgesic activities using rats mice. Inflammatory activity MECN assessed by carrageenan-induced paw oedema while acetic acid -induced writhing formalin lick test. Histological analyses the paws were also carried out. There evaluation mechanism(s) action naloxone, a blocker opioid receptors; atropine, muscarinic propranolol, beta adrenergic receptors. Findings from study revealed that has both properties....

Abstract Background : Ethanolic leaf extract of Cnidoscolus aconitifolius was evaluated for analgesic and anti-inflammatory activities. Methods The activity the assayed by formalin-induced paw licking test, acetic acid-induced abdominal writhing hot plate whereas its determined effects on carrageenan-induced edema. Results C. prolonged reaction time mice to pain in a dose-dependent manner. optimal effect obtained when administered 90 min before stimulation test. (100 or 200 mg/kg b.w.)...

Abstract Purpose Ocimum gratissimum L. leaves has been traditionally used for management of febrile illnesses and symptoms typified sickness behavior. In this work we investigated the modulatory effect flavonoid-rich fraction O. (EAFOg) on behavior, inflammatory oxidative stress responses in LPS-challenged mice. Method leaf was first extracted with n-hexane, chloroform methanol, EAFOg obtained by ethylacetate partitioning a sequentially resultant methanol extract. The (25–100 mg/kg) acute...

Objectives: Honey contains phenolic acids and flavonoids, which are significant in developing drugs against neuroinflammation. The study was designed to evaluate the ameliorative potential of honey lipopolysaccharides-induced neuroinflammation.Methods: Thirty male Wistar rats were divided into six groups, namely: control group (10 mL/kg vehicle), LPS only (250 µg/kg), (0.26, 0.31 0.36 g/kg) ibuprofen (100 mg/kg). µg/kg i.p) administered for 7days followed by treatment with Ibuprofen another...

Parkinson's disease (PD) is a chronic neurodegenerative that occurs progressively with time. Current PD treatments are symptomatic moderate effects on striatal dopamine release. Previously, the ethnomedicinal benefits of Zingiber officinale Roscoe have been demonstrated to possess broad range pharmacological benefits, but no single data its effect against nigrostriatal degeneration in model has reported. Proactive neuroprotective and pharmacotherapeutic approaches asymptomatic needed prevent...

Ameliorative effects of Musa sapientum peel extract (MSPE) were studied on Acetic Acid (AA)-induced colitis in rats. From a dose response study, the effective and yet, safe for treatment AA-induced rats was determined, also, further study carried out to determine fraction(s) MSPE that will be useful AA induced Colitis with 0.2 ml 6% acetic acid through lower abdominal laparotomy. Treatment graded doses methanolic dried (MS) (50, 100 200 mg/kg) 7 days showed 50 mg/kg as an optimal healing...

:Lipopolysaccharides (LPS) is an agent that used to initiate neuroinflammation in animal experimental model. Thus, leading neurotoxicity and behavioral deficit. These effects are thought be caused by significant increase the level of pro-inflammatory mediators Central nervous system. However, not much known about anti-neuroinflammatory properties Waltheria americana leaf LPS- induced neuroinflammation. purpose this study was evaluate methanol extract (MEWA) animals. : Leaves W. were...
