In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[Q]: Context: Burns cause thermal injury to local tissue and trigger systemic acute inflammatory processes, which may lead to multiple distant organ dysfunction. We investigated the protective effect of dietary whey supplementation on distant organs in a rat model.', 'Forty-eight rats were divided into six groups of eight: groups 1 and 2 were the controls, fed a standard diet and a whey-supplemented diet, respectively; groups 3 and 4 were fed a standard diet and subjected to burn injury; and groups 5 and 6 were fed a whey-supplemented diet and subjected to burn injury. We measured the oxidative stress variables, as well as glutathione in the liver and kidney, and histologically examined skin samples obtained 4 h (groups 3 and 5) and 72 h (groups 4 and 6) after burn injury.', 'Glutathione (GSH) levels remained the same in the liver but were slightly elevated in the kidneys after burn injury in the rats fed a standard diet. Whey supplementation caused a significant increase in hepatic GSH levels 4 h after burn injury. Moreover, there was a significant rebound effect in the liver and kidney GSH levels after 72 h and whey supplementation potentiated this effect. Hepatic and renal lipid peroxide levels were also increased 4 h after burn injury in the rats fed a standard diet. Whey supplementation significantly suppressed the burn-induced increase in hepatic and renal lipid peroxide levels. Histological examination revealed that although whey supplementation resulted in decreased subepidermal inflammation, the indicators of wound healing and collagen deposition were not improved.\Question: Does whey feeding suppress the measurement of oxidative stress in experimental burn injury?
[A]: Whey pretreatment suppressed hepatic and renal oxidative stress measurements after experimental burn injury.


[Q]: Context: Progress in the management of patients with medically intractable epilepsy is impeded because we do not fully understand why pharmacoresistance happens and how it can be predicted. The presence of multiple seizures prior to medical treatment has been suggested as a potential predictor of poor outcome. In the present study, we used an animal model of temporal lobe epilepsy to investigate whether pharmacoresistant rats differ in seizure frequency from pharmacoresponsive animals.', 'Epilepsy with spontaneous recurrent seizures (SRS) was induced by status epilepticus. Frequency of SRS was determined by video/EEG (electroencephalography) monitoring in a total of 33 epileptic rats before onset of treatment with phenobarbital (PB).', 'Thirteen (39%) rats did not respond to treatment with PB. Before treatment with PB, average seizure frequency in PB nonresponders was significantly higher than seizure frequency in responders, which, however, was due to six nonresponders that exhibited > 3 seizures per day. Such high seizure frequency was not observed in responders, demonstrating that high seizure frequency predicts pharmacoresistance in this model, but does not occur in all nonresponders.\Question: Is high seizure frequency prior to antiepileptic treatment a predictor of pharmacoresistant epilepsy in a rat model of temporal lobe epilepsy?
[A]: The data from this study are in line with clinical experience that the frequency of seizures in the early phase of epilepsy is a dominant risk factor that predicts refractoriness. However, resistance to treatment also occurred in rats that did not differ in seizure frequency from responders, indicating that disease severity alone is not sufficient to explain antiepileptic drug (AED) resistance. These data provide further evidence that epilepsy models are useful in the search for predictors and mechanisms of pharmacoresistance.


[Q]: Context: To determine the effect of castration on hippocampal function, we have investigated synaptic transmission in the castrated male mouse in vivo. We also examined whether administering testosterone can reverse the changes.', 'Male 12 weeks-old C57BL/6J mice were divided into three experimental groups; sham-castration (Control), the castration group (Cast), and the castration plus testosterone propionate group (Cast+TP). Field excitatory postsynaptic potentials (fEPSP) were evoked in the CA1 area of the hippocampus by stimulating the commissural fibers of the contralateral hippocampus. Field EPSPs were evoked in the granular cells of the dentate gyrus (DG) by stimulating the ipsilateral perforant path fibers.', 'Laminar analysis of the fEPSPs in the hippocampal CA1 pyramidal cell layer did not differ significantly between the three experimental groups. However, paired pulse facilitation (PPF) of the fEPSP with short inter-stimulus intervals (30 to 100 msec) was significantly suppressed in Cast group. This suppression was reversed by testosterone injection (Cast+TP). Longterm potentiation (LTP) in the CA1 pyramidal neurons by high frequency stimulation (HFS) did not differ significantly between the three experimental groups, whereas potentiation evoked by primed burst stimulation (PBS) was much weaker in the Cast group compared with the Control group. Testosterone injection restored the PBS-induced potentiation to the control level. Synaptic transmission between perforant pathway and the granule cells in the dentate gyrus (DG) did not differ significantly among the three experimental groups.\Question: Is altered synaptic transmission in the hippocampus of the castrated male mouse reversed by testosterone replacement?
[A]:
Suppression of PPF and impairment of the potentiation by PBS in CA1 hippocampal neurons was observed in castrated male mice and these changes were reversed by testosterone injection. These findings suggest that altered synaptic transmission in the castrated male mouse is caused by disturbance of inhibitory neuronal networks that are influenced by testosterone.
