Cysteamine Attenuate Intestinal Reperfusion Injury Induced by Occlusion of Mesenteric Artery by Enhancing Intracellular Thiol Activities.

Background: Ischemia/reperfusion has been reported to further damage the intestine reperfusion injury (IRI) and cause multiple distal organ dysfunction through oxidative stress, inflammation, and apoptosis. Cysteamine is known to inhibit oxidative stress, inflammatory cytokines and apoptosis. This experiment was designed to evaluate the role of cysteamine against IRI in rats METHODS: Thirty-two Wistar rat strains were assigned to four groups: sham, Intestinal-reperfusion injury (IRI), 50 mg/kg and 100 mg/kg cysteamine treatment IRI.

Cysteamine mitigates torsion/detorsion-induced reperfusion injury via inhibition of apoptosis, oxidative stress and inflammatory responses in experimental rat model.

Oxidative stress, inflammation and apoptosis are major pathways in pathophysiology of testicular torsion/detorsion (TTDT) reperfusion injury. This study evaluated the antioxidant, anti-inflammatory and anti-apoptotic role of cysteamine in TTDT-induced injury. Male Wistar rats (n = 32) were grouped into four (n = 8): sham, ischaemia-reperfusion injury (IRI), cysteamine (100 mg/kg and 200 mg/kg) for in vivo study.

Neuroprotective and memory-enhancing effects of methanolic leaf extract of in rat model of type 2 diabetes mellitus.

This study investigated the effect of methanolic leaf extract of (MEPb) on type 2 diabetes mellitus (T2DM) associated cognitive decline in Wistar rats. 36 male rats weighing 130-200 g were assigned into 6 groups (n = 6) as follows: normal control, diabetic control, pioglitazone-treated diabetic and three MEPb-treated diabetic groups, type 2 diabetes mellitus was induced with low dose streptozocin (STZ) injection following 3 weeks of high fat diet (HFD) intake. Thirty days after diabetes induction, rats exhibited marked and persistent hyperglycemia, animals were treated with MEPb (50, 100 and 200 mg/kg) and pioglitazone (10 mg/kg) as standard.

Protective effects and chemical composition of Corchorus olitorius leaf fractions against isoproterenol-induced myocardial injury through p65NFkB-dependent anti-apoptotic pathway in rats.

Background The fractions of Corchorus olitorius leaf (COLF) were evaluated against oxidative stress, inflammation and apoptosis in isoproterenol (ISO)-induced myocardial injury (MI) Wistar rats. Methods The n-hexane, dichloromethane, ethylacetate and ethanol fractions were obtained from COLF extract. Male Wistar strains were randomly grouped into 11 groups (n = 6 in each group), which comprises normal control group, MI control group, 4 fraction groups with two doses (50 and 100 mg/kg) and enalapril (10 mg/kg).

Subchronic exposure to ; its neurotoxic potentials in young adult female Wistar rats.

Background: (camphor) {CHO} is a chemical substance used mostly amongst the Yoruba ethnic group in Western Nigeria to treat infantile colic during early childhood. This study assess the neurotoxic potentials of following sub-chronic exposure in female albino Wistar rats.

Methods: Twenty-eight female rats (mean weight of 130 g) were randomly selected and assigned into four (4) groups.
