Inoculation of rats with Mycobacterium butyricum produced an arthritis of the limbs which revealed an enhanced sensitivity to noxious mechanical pressure (hyperalgesia). Arthritic rats displayed a pronounced rise in immunoreactive dynorphin in lumbo-sacral spinal cord which correlated both with the intensity and time-course of this hyperalgesia. MR-2266, a(More)
Insulin-like growth factor-I (IGF-I) is implicated in the development, survival and maintenance of function of sympathetic and sensory neurons. These neurons are affected at an early stage during the course of diabetes. Reverse transcriptase polymerase chain reaction (RT-PCR) based assay revealed that rat superior cervical ganglia (SCG) express mRNA(More)
Impaired glucose uptake and metabolism by peripheral tissues is a common feature in both type I and type II diabetes mellitus. This phenomenon was examined in the context of oxidative stress and the early events within the insulin signalling pathway using soleus muscles derived from non-obese, insulin-resistant type II diabetic Goto-Kakizaki (GK) rats, a(More)
1 Rats failed to drink a flavoured solution when its consumption had been followed by injection of amphetamine (conditioned taste aversion).2 There was very little difference between the potencies of (+)- and (-)-amphetamine.3p-Chloromethamphetamine was a more potent aversive agent than methamphetamine.4 Strong taste aversions were also conditioned with(More)
Rats would not drink distinctively flavoured solutions after their previous ingestion had been followed by injection of amphetamine (1 mg/kg). In the same rats, intake of flavoured solutions followed by saline injections was not suppressed. Providing the rats with cues as to the location of flavoured solutions paired with amphetamine did not alter either(More)
Rats receiving twice-daily morphine injections acquired aversions to a saccharin solution which had been presented for 1 hr immediately prior to injections of naloxone. The degree of aversion was related to the maintenance dosage of morphine. Rats maintained on a regimen of daily saline injections did not show significant aversion to saccharin paired with(More)
If endorphins mediate various behavioural states including reactions to stress and social affect, then experimental manipulation of such states should alter the stimulus properties of opioid antagonists. The results of experiments in which the aversiveness of naloxone was increased by chronic environmental stress produced by rearing and maintaining male(More)
