In this work, it has been attempted to determine the alterations brought about in the enzyme activities by oral administering acetone, isopropanol and ethanol to chemically induced diabetic rats. The rats in whom diabetes was induced diabetic by 65 mg/kg streptozotocin (stz) were divided into four main groups as a stz alone (group I), stz + aceton (group II), stz + isopropanol (group III), stz ...
The antioxidant activities of fermented red ginseng (FRG) were investigated in vitro and in vivo. The contents of total polyphenol and total flavonoid in FRG extracts were 17.01±2.00 μg/mg and 18.42±3.97 μg/mg, respectively. These extracts were capable of directly scavenging α, α-diphenyl-picrylhydrazyl free radicals. The antioxidative effects of the FRG extracts in streptozotocin (STZ)-induced...
We have evaluated the influence of oligofructose (OFS), a fermentable dietary fibre, on glucose homeostasis, insulin production and intestinal glucagon-like peptide-1 (GLP-1) in streptozotocin-treated diabetic rats. Male Wistar rats received either i.v. streptozotocin (STZ; 40 mg/kg) or vehicle (CT); one week later, they were fed for 6 weeks with either the standard diet (STZ-CT), or with a die...
Diabetes is associated with endothelial dysfunction and platelet activation, both of which contribute to increased cardiovascular risk. We investigated whether the selective mineralocorticoid receptor (MR) antagonist eplerenone improves endothelial dysfunction and reduces platelet activation in diabetic rats. Male Wistar-rats were injected with streptozotocin (50 mg/kg i.v.) to induce insulin-d...
In wild-type mice, a single injection of streptozotocin (STZ, 200 mg/kg body wt) caused within 4 days severe hyperglycemia, hypoinsulinemia, significant glucose intolerance, loss of body weight, and the disappearance of pancreatic beta-cells. However, in ATP-sensitive K(+) channel (K(ATP) channel)-deficient mice (Kir6.2(-/-) mice), STZ had none of these effects. Exposing isolated pancreatic isl...
Diabetes is a metabolic disorder characterized by hyperglycemia resulting from either the deficiency in insulin secretion or action of can affect numerous different organ systems body and, over time, lead to serious complications. Complications are microvascular macrovascular. To evaluate anti-diabetic effect Phyllanthus niruri silver nano-particles. Streptozotocin (STZ) 50mg/kg used induce dia...
Diabetes mellitus is considered as a risk factor of Alzheimer's disease (AD), the front runner of neurodegenerative disorders. Streptozotocin (STZ) is a toxin for pancreatic β-cell, which can construct a model of insulin deficient diabetes through intraperitoneal or intravenous injection. A model generated by intracerebroventricular STZ (icv-STZ) also shows numerous aspects of sporadic AD. The ...
The state of lipid peroxidation (LPO), respiration and oxidative phosphorylation, mitochondrial permeability transition pore (mPTP) antiradical activity rat liver mitochondria in streptozotocin (STZ)-induced diabetes condition were studied, considered the ways correction detected membrane damages with use gossitan, isolated from cotton plant Gossypium hirsutum L. It was shown that rate states V...
We investigated the effects of diabetes mellitus and antioxidant treatment on the sensory and reflex function of cardiac chemosensory nerves in rats. Diabetes was induced by streptozotocin (STZ; 85 mg/kg ip). Subgroups of sham- and STZ-treated rats were chronically treated with an antioxidant, vitamin E (60 mg/kg per os daily, started 2 days before STZ). Animals were studied 6-8 wk after STZ in...
Streptozotocin (STZ) is believed to induce pancreatic beta cell death in mice by depleting the cell of NAD+NADH. The drug is known to cause a greater depletion of beta cell NAD+NADH in C57bl/6J mice than in Balb/c mice. To investigate the basis for this strain difference, we compared the effects of streptozotocin on poly(ADP-ribose)polymerase (PARP) activation - the major site of NAD consumptio...
