Injury or dysfunction of somatosensory system induces a complex syndrome called neuropathic pain, which still needs adequate pharmacological control. The current pharmacological treatments were in part developed from natural compounds. Flavonoids are natural polyphenolic molecules presenting varied biological activities and low toxicity. The flavonoid diosmin is a safe compound with good tolerability and low toxicity. This study evaluated the antinociceptive effect of diosmin in the sciatic nerve chronic constriction injury (CCI)-induced neuropathic pain model...

BACKGROUND: Prevention of cognitive impairment and dementia is an important public health goal. Epidemiological evidence shows a relationship between cognitive impairment and Type 2 diabetes mellitus. The risk of dementia increases with duration of disease. This updated systematic review investigated the effect on cognitive function of the type of treatment and level of metabolic control in people with Type 2 diabetes. OBJECTIVES: To assess the effects of different strategies for managing Type 2 diabetes mellitus on cognitive function and the incidence of dementia...

Mantidis ootheca (Sang Piao Xiao) is well known mantis eggs in a foamy pouch. The purpose of the present study was to investigate the underlying cellular mechanisms of the nitric oxide (NO)-releasing property of the aqueous extract of Mantidis ootheca (AMO) in rat aorta and vascular endothelial cells. AMO was examined for its vascular relaxant effect in isolated phenylephrine-precontracted rat thoracic aortic rings. The roles of the nitric oxide (NO) signaling in the AMO-induced effects were tested in human umbilical vein endothelial cells (HUVECs)...

The purpose of this study was to validate a rapid, simple, and accurate method using ultra performance liquid chromatography (UPLC) for the simultaneous determination of 26 anti-diabetic compounds in illegally adulterated dietary supplements. The method was validated for specificity, linearity, limit of detection, limit of quantitation, precision, accuracy, recovery, and stability. All compounds were separated with a resolution of over 1.5. The limits of detection and quantitation were 0.10-1.70 and 0.30-5...

The aim of this study was to investigate the antinociceptive potential of (-)-epicatechin and the possible mechanisms of action involved in its antinociceptive effect. The carrageenan and formalin tests were used as inflammatory pain models. A plethysmometer was used to measure inflammation and L5/L6 spinal nerve ligation as a neuropathic pain model. Oral (-)-epicatechin reduced carrageenan-induced inflammation and nociception by about 59 and 73%, respectively, and reduced formalin- induced and nerve injury-induced nociception by about 86 and 43%, respectively...

The Interagency Emergency Health Kit (IEHK) provides a standard package of medicines and simple medical devices for aid agencies to use in emergencies such as disasters and armed conflicts. Despite the increasing burden of non-communicable diseases (NCDs) in such settings, the IEHK includes few drugs and devices for management of NCDs. Using published data to model the population burden of acute and chronic presentations of NCDs in emergency-prone regions, we estimated the quantity of medications and devices that should be included in the IEHK...

The aim of the present study was to investigate the effects of aqueous extract of black pepper and ajwa seed on liver enzymes in alloxan-induced diabetic Wister albino rats to show the preventive and ameliorating effects in hyperglycemic rats. Rats were divided into 6 groups; normal control rats, diabetic control rats, glibenclamide treated rats, black pepper treated rats, ajwa seed treated rats and black pepper plus ajwa seed treated rats. Hyperglycemia was induced in the treatments groups by a single intraperitoneal injection of alloxan at 150 mg/kg body weight...

OBJECTIVE: To investigate the possible role of fesoterodine (a competitive muscarinic receptor antagonist) on erectile dysfunction (ED) in streptozotocin-induced diabetic rats. MATERIALS AND METHODS: A total of 16 adult male Sprague-Dawley rats were equally divided into control and diabetic group. Diabetes was induced by a single intravenous injection of streptozotocin (25-35mg/kg). In vivo erectile responses were evaluated by the stimulation of cavernosal nerves and repeated after intracavernosal injection of fesoterodine (1µM) in rats...

The role of KATP channels in myocardial infarct size-limiting effect of chronic continuous normobaric hypoxia was examined in a rat model based on a 20-min coronary occlusion and subsequent 3-h reperfusion. Rats were adapted to normobaric hypoxia (12% O2) for 21 days. This hypoxia produced a pronounced infarct size-limiting effect, which had been prevented by 0.3 mg/kg glibenclamide, a non-selective inhibitor of entire pool of KATP channels, or 5 mg/kg 5-hydroxydecanoate, an inhibitor of mitochondrial KATP channels...

Bambusa balcooa (Poaceae) is native to India and has been used traditionally by the tribes of Northeast India to treat diabetes. The present investigation was aimed to evaluate the toxicity, anti-diabetic activity along with in vitro antioxidant activity of the leaf of B. balcooa in alloxan-induced diabetic rats and also identify active compounds by using HPLC. The acute toxicity test of aqueous extract of B. balcooa leaf revealed that the median lethal dose (LD50) of B. balcooa aqueous extract (BAQE) was 5...

Diabetic encephalopathy is an important complication of diabetes characterized by cognitive impairment, neurochemical and structural abnormalities. This study aimed to investigate the effect of coenzyme Q10 (CoQ10) and niacin as well as their combination in the treatment of encephalopathy associated with streptozotocin (STZ)- induced diabetes in rats. Glibenclamide (reference diabetic drug) and donepezil hydrochloride (acetylcholinesterase inhibitor) were also evaluated. Diabetes was induced by a single intraperitoneal injection of STZ (60 mg/kg)...

We investigated the antidiabetic effect of Moringa olifeira Lam. in a diet-induced obesity (DIO) mouse model. Six mice were randomly selected as normal controls. Moringa olifeira Lam. leaf extract at a dose of 200, 400 or 600 mg/kg body weight, glibenclamide (Glib) at the dose of 10 mg/kg (positive control) and distilled water at 10 ml/kg (control group) were administered orally by gastric intubation, and each group consisted of six mice. Insulinsensitive tissues (liver, skeletal muscle) were collected to investigate antidiabetic effects and examine the plant's molecular mechanisms...

The optimum treatment for HNF1A/HNF4A maturity-onset diabetes of the young and ATP-sensitive potassium (KATP ) channel neonatal diabetes is sulfonylureas outside pregnancy, but there is little evidence regarding the most appropriate treatment during pregnancy. Glibenclamide has been widely used in the treatment of gestational diabetes, but recent data have established that glibenclamide crosses the placenta and increases risk of macrosomia and neonatal hypoglycaemia. This raises questions about its use in pregnancy...

Medicinal plants have been widely used in the treatment of chronic pain. In this study, we describe the antinociceptive effect of the essential oil from Croton conduplicatus (the EO 25, 50, and 100 mg/kg, i.p.), a medicinal plant native to Brazil. Antinociceptive activity was investigated by measuring the nociception induced by acetic acid, formalin, hot plate and carrageenan. A docking study was performed with the major constituents of the EO (E-caryophyllene, caryophyllene oxide, and camphor). The EO reduced nociceptive behavior at all doses tested in the acetic acid-induced nociception test (p < 0...

Two antidiabetic compounds named 4-methoxybenzo[b]azet-2(1H)-one (1) and 3β-hydroxy-35-(cyclohexyl-5'-propan-7'-one)-33-ethyl-34-methyl-bacteriohop-16-ene (2) together with stigmasterol and β-sitosterol were isolated from the aerial part of Roylea cinerea (D.Don) Baill. The structures of these compounds were elucidated by advanced spectroscopic methods, including two-dimensional NMR and MS techniques. These compounds were evaluated for their antidiabetic efficacy using in vitro and in vivo methods. Both compounds (1 and 2) showed a significant decline in blood glucose level of alloxan-induced diabetic rats at 10 mg/kg, p...

The mechanism underlying the intestinal absorption of perfluorooctanoic acid (PFOA) was investigated using Caco-2 cells. The uptake of PFOA from the apical membrane of Caco-2 cells was fast, and pH, temperature, and concentration dependent, but Na(+) independent. Coincubation with sulfobromophthalein (BSP), glibenclamide, estron-3-sulfate, cyclosporine A or rifamycin SV, which are typical substrates or inhibitors of organic anion transporting polypeptides (OATPs), significantly decreased the uptake of PFOA...
