Behavioral changes of Wistar rats with experimentally-induced painful diabetic neuropathy

Behavioral changes of Wistar rats with experimentally-induced painful diabetic neuropathy.

With the purpose of studying data on spontaneous customary changes in diabetic rats, we induced diabetes in 28 Wistar rats with streptozotocin. The animals were observed for 27 weeks in an attempt to characterize spontaneous customary changes that could suggest signs of chronic pain. Morphine, as a central-acting potent analgesic and its specific antagonist naloxone, were used. Our results evid...

Painful Diabetic Neuropathy

N europathic pain exerts a substantial impact on quality of life, particularly by causing considerable interference in sleep, daily activities, and enjoyment of life. Chronic neuropathic pain is present in 13–26% of diabetic patients (1– 4). In a recent survey from Augsburg, Germany, the prevalence of painful polyneuropathy was found to be 13.3% in diabetic subjects, 8.7% in individuals with im...

Painful diabetic neuropathy.

PDN is commonly caused by involvement of either the C fibres or the Aδ fibres. PDN caused by the involvement of small nerve fibers (C fibres), may present without objective clinical findings, such as decreased peripheral reflexes or abnormalities, on routine electrophysiological studies. Small fiber neuropathies may manifest as a number of different clinical symptoms, including allodynia, burni...

Electrophysiological changes in optic neuropathy of streptozotocin induced diabetic rats

UNLABELLED The visually evoked potentials are electrical signals generated by the occipital cortex due to electrical stimulus. The clinical importance of VEP is to diagnose the functional changes of the optic nerve in different diseases such as diabetic mellitus. Our study sought latency of VEP changes depending on glycemic value and duration of diabetes in Wistar rats. METHODS this study eva...
