Abstract

Numerous studies have shown the deleterious effects of sleep deprivation (SD) on memory. However, SD in various durations may induce different effects. Studies have reported that short-term or acute SD can improve cognitive functions. In addition, streptozotocin (STZ) significantly impairs learning and memory, and induces inflammation and oxidative stress. In this study, we aimed to investigate the effect of two types of SD (short term: 6 h; long term: 24 h) on STZ-induced spatial memory impairment in rats, with respect to the serum level of catalase (CAT), malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1beta (IL-1β). Morris water maze apparatus was used to assess spatial memory performance and STZ was injected i.c.v., twice, and at the dose of 3 mg/kg, at an interval of 48 h. The results showed that only 24 h SD impaired spatial learning and memory in rats. In addition, 24 h SD attenuated anti-oxidant activity and increased the level of pro-inflammatory markers in the serum. STZ impaired spatial learning and memory, and attenuated anti-oxidant activity and increased the level of pro-inflammatory markers in the serum of rats. Furthermore, 6 h SD slightly and partially improved spatial memory and significantly improved anti-oxidant activity in rats, with no effect on STZ-induced inflammation. We suggest that STZ has more important mechanisms that are involved in its memory impairment effect, and maybe, STZ-induced inflammation has a more important role. We also suggest more detailed studies to investigate the potential therapeutic effect of SD (in different durations) on memory function, oxidative stress, and inflammation. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
