The role of nitric oxide (NO) in the regulation of the intrarenal microcirculation in streptozotocin (STZ)-induced diabetes mellitus in rats is not clear. We examined renal cortical and papillary hemodynamics in STZ rats and determined the effects of systemic inhibition and stimulation of NO synthesis. Renal blood flow in cortical (QCC), and inner medullary ascending (QAV) and descending (QDV) ...

PURPOSE The aim of this study was to investigate the effect of treadmill exercise on inflammatory response in streptozotocin (STZ)-induced animal model of Alzheimer's disease (AD). METHODS To induce the animal model of AD, Sprague-Dawley rats were injected into intracerebroventricular (ICV) injection with 1.5 mg/kg of STZ. Rats were divided into three groups as Sham-con group (n = 7), STZ-con...

In the area of drug discovery, repurposing strategies represent an approach to discover new uses approved drugs besides their original indications. We used this investigate effects dimethyl fumarate (DMF), a for relapsing–remitting multiple sclerosis and psoriasis treatment, on early injury associated with diabetic retinopathy (DR). in vivo streptozotocin (STZ)-induced rat model. Diabetes was i...

Abstract Alzheimer disease (AD) is a chronic and progressive neurodegenerative disorder characterized by memory loss cognition impairment. A link has been established between AD epilepsy sharing multiple mechanisms pathogenesis. Similar Hippocampal changes have found both diseases. Choosing antiepileptic drug in patient represent great challenge especially with increase seizure risk patients. L...

Relevance. To conduct a preclinical evaluation of the effectiveness antidiabetic drugs, models simulating pathogenesis and main manifestations diabetes mellitus (DM) in humans are needed. The streptozotocin (STZ) model, which has received most widespread use experiment, does not allow reproducing stepwise multifactorial development type 2 diabetes. Goal. develop model using high-carbohydrate di...

The gastrointestinal system may be involved in the etiopathogenesis of insulin-resistant brain state (IRBS) and Alzheimer’s disease (AD). Gastrointestinal hormone glucagon-like peptide-1 (GLP-1) is being explored as a potential therapy activation GLP-1 receptors (GLP-1R) exerts neuroprotection controls peripheral metabolism. Intracerebroventricular administration streptozotocin (STZ-icv) used t...

Refractory wound is a severe complication that leads to limb amputation in diabetes. Endothelial nitric oxide synthase (eNOS) plays a key role in normal wound repair but is uncoupled in streptozotocin (STZ)-induced type 1 diabetes because of reduced cofactor tetrahydrobiopterin (BH(4)). We tested the hypothesis that overexpression of GTP cyclohydrolase I (GTPCH I), the rate-limiting enzyme for ...

Acetaminophen (APAP) hepatotoxicity is mediated by N-acetyl- p -benzoquinone imine (NAPQI), a highly toxic metabolite generated cytochrome P450 2E1 (CYP2E1). Thus, pathological conditions increasing CYP2E1 activity can favour APAP-induced liver injury, which characterized massive hepatocellular necrosis and secondary sterile inflammation. In recent work, Wang et al. showed that was exacerbated ...

The aim of the present study was to evaluate antihyperglycemic activity of methanol extract of Citrus maxima leaf (MECM) in streptozotocin (STZ; 65 mg/kg b.w.) induced diabetic rats. Three days after STZ induction, diabetic rats received MECM orally at a dose of 200 and 400 mg kg-1 body weight daily for 15 days. Glibenclamide (0.5 mg kg-1 p.o.) was used as a reference drug. Blood glucose levels...

Streptozotocin (STZ) is used extensively to induce pancreatic beta-cell death and ultimately diabetes mellitus in animal models. However, the direct effects of STZ on muscle are largely unknown. To delineate the effects of STZ from the effects of hypoinsulinemia/hyperglycemia, we injected young rats with 1) saline (control), 2) STZ (120 mg/kg) or 3) STZ and insulin (STZ-INS; to maintain euglyce...
