introduction: kisspeptin-13 (kp-13) is a novel endogenous factor, increases synaptic transmission and is involved in several behavioral functions such as anxiety, locomotion, epilepsy and avoidance learning. however, the role of this peptide on cognition has not been well clarified yet. here we studied the effect of kisspeptin-13 pretreatment on spatial learning and also interaction with cholin...

Possible involvement of lipid peroxide (LPO) in the occurrence of diabetic retinal lesion was investigated using streptozotocin-induced diabetic rats. Young male Wistar rats weighing 100-150 g were made diabetic by daily intraperitoneal injection of 30 mg/kg streptozotocin (STZ) for 5 days. Five weeks after the termination of STZ-treatment, when animals maintained typical hyperglycemia, the tis...

With an objective to develop Complementary and Alternative Medicine for the treatment of diabetic nephropathy, the present study investigated the protective effects of methanolic extract of Punica granatum leaves (MPGL) in streptozotocin-induced diabetic nephropathy. Diabetic nephropathy has become a leading cause of end stage renal failure worldwide. P. granatum, due to its anti-diabetic, anti...

background & objectives: streptozotocin (stz) is used for induction of type-1 diabetes mellitus in animal models. its beta-cytotoxic action results in sudden release of insulin leading to severe hypoglycaemia and even mortality. however, its sensitivity varies with species. present investigation was aimed at studying stz induced acute clinical effects in rabbits. methods: streptozotocin@ 65...

The objective of the present investigation was to study antidiabetic activity of standardized extract of Trigonella foenum-graecum seeds (IND01) using neonatal streptozotocin-induced rat (n-STZ) model of diabetes mellitus (DM) in rats for the first time. Streptozotocin (STZ) was injected (50 mg/kg i.p.) in pups of rats in a split dose manner (on 2nd and 3rd postnatal days). After 8 weeks, DM wa...

In rats with diabetes induced by streptozotocin (STZ), we studied the reactivity of the aorta in response to vasoconstrictor and vasorelaxant agents, changes in conduction velocity in the sciatic nerve, and glutathion (GSH) content in the gastric mucosa as well as the occurrence of spontaneous gastric lesions. STZ-induced diabetes was found to be accompanied by endothelial injury, exhibited by ...

This study investigated the effect of morin on membrane bound enzymes and glycoproteins in normal and streptozotocin (STZ)-induced diabetic Wistar rats. Diabetes was induced in rats by an intraperitoneal injection of STZ, dissolved in citrate buffer (0.01 M, pH 4.5) and injected to overnight fasted rats with a dose of STZ 50 mg/kg. Morin was dissolved in carboxy methyl cellulose (CMC) at a dose...

The present investigation was undertaken to study the effects of chronic oral ramipril (1 mg/kg) treatment in streptozotocin (STZ) induced diabetic rats. Single tail vein injection of STZ (45 mg/kg, i.v.) produced a diabetic state exhibiting all the cardinal symptoms such as loss of body weight, polydipsia, polyuria, glucosuria, polyphagia, hypoinsulinaemia and hyperglycaemia. The diabetic stat...

PURPOSE Fumaria parviflora Lam (Fumariaceae) has been used in traditional medicine in the treatment of several diseases such as diabetes. The present work was designed to evaluate the hypoglycaemic effects of methanolic extract (ME) of F. parviflora in normal and streptozotocin-induced diabetic rats. METHODS The rats used were allocated in six (I, II, III, IV, V and VI) experimental groups (n...

We investigated the effects of streptozotocin (STZ)-induced diabetes on thyroid hormone levels, type 1 deiodinase (D1) activity and messenger RNA (mRNA) levels in inherited D1 deficient C3H mice in a comparative manner with control C57 mice. The apparent maximum velocity (Vmax) D1 values in C3H mice were 3% (liver) and 26% (kidney) of those in C57 mice. In C3H mice, similar serum T3, slightly h...
