Acetaldehyde (ACD) is the first metabolite of ethanol. Although, the role of ACD in ethanol addiction has been controversial, there are data showing a relationship. The objective of the current study was to further test the hypothesis that ACD itself is reinforcing. For this reason, we carried out a study on operant oral ACD self-administration. Wistar rats were trained to self-administer tap w...

The objective of the present study was to evaluate sphingolipid levels (sphingosine-So and sphinganine-Sa) and to compare the Sa/So ratio in liver, serum and urine of Wistar rats after prolonged administration (21 days) of fumonisin B(1) (FB(1)). In parallel, the kinetics of sphingolipid elimination in urine was studied in animals receiving a single dose of FB(1). Prolonged exposure to FB(1) ca...

Wistar rats were exposed to a 916 MHz, 10 W/m(2) mobile phone electromagnetic field for 6 hours a day, 5 days a week. Average completion times in an eight-arm radial maze were longer in the exposed rats than control rats after 4-5 weeks of exposure. Error rates in the exposed rats were greater than the control rats at 6 weeks. Hippocampal neurons from the exposed rats showed irregular firing pa...

In the present study, the effect of minocycline was studied against intracerebroventricular streptozotocin induced spatial memory deficit. Male wistar rats were injected with intracerebroventricular streptozotocin bilaterally. The rats were treated chronically with Minocycline (10, 20 and 40 mg/kg, ip) for 17 days starting from day 1 of streptozotocin injection in separate groups. The spatial m...

BACKGROUND Every year, millions of people are exposed to avoidable, life-threatening risks through the trans-fusion of unsafe blood. AIM To determine the survival time of Treponema pallidum in banked donor blood. MATERIAL AND METHODS Two groups of male Wistar rats (group A and B) were inoculated intratesticularly with 0.5ml of artificially infected donor blood (final density of Nichols trep...

Anti-inflammatory activity of Indonesian polyherbal product containing Curcuma zanthorrhiza and Vitex trifolia as the main ingredients in carrageenan- histamine-induced inflammation Wistar rats

The prevalence of type 2 diabetes mellitus (T2DM) and hypertension has markedly increased worldwide. The purpose of the present study was to examine the effects of a high-salt intake on the systolic blood pressure (SBP) and vascular responses in WBN/Kob-Leprfa/fa (WBKDF) rats, a new spontaneous animal model of T2DM. Male WBKDF rats and age-matched Wistar rats at 6 weeks of age were each divided...

In our studies with spontaneously hypertensive (SHR), Wistar-Kyoto (WKY), and Wistar rats, we observed normotensive WKY rats with cardiac hypertrophy determined by a greater left ventricular (LV) mass (LVM)-to-body weight (BW) ratio (LVM/BW) than that of normotensive Wistar rats. Thus we compared the following parameters in SHR, WKY, and Wistar rats: LVM/BW, cell capacitance as index of total s...

Protein kinase C (PKC) is a family of protein kinases controlling protein phosphorylation and playing important roles in the regulation of metabolism. We have investigated expression levels of PKC isoforms in pancreatic islets and liver of diabetic Goto-Kakizaki (GK) rats with and without insulin treatment to evaluate their association with glucose homeostasis. mRNA and protein expression level...
