Protective effects of maternal administration of curcumin and hesperidin in the rat offspring following repeated febrile seizure: Role of inflammation and TLR4.
    International immunopharmacology, 2020, Volume: 86

    Neuroinflammation has a key role in seizure generation and perpetuation in the neonatal period, and toll-like receptor 4 (TLR4) pathway has a prominent role in neuroinflammatory diseases. Administration of antioxidants and targeting TLR4 in the embryonic period may protect rat offspring against the next incidence of febrile seizure and its harmful effects. Curcumin and hesperidin are natural compounds with anti-inflammatory and antioxidant properties and have an inhibitory action on TLR4 receptors. We evaluated the effect of maternal administration of curcumin and hesperidin on infantile febrile seizure and subsequent memory dysfunction in adulthood. Hyperthermia febrile seizure was induced on postnatal days 9-11 on male rat pups with 24 h intervals, in a Plexiglas box that was heated to ~45 °C by a heat lamp. We used enzyme-linked immunosorbent assay, Western blotting, malondialdehyde (MDA), and glutathione (GSH) assessment for evaluation of inflammatory cytokine levels, TLR4 protein expression, and oxidative responses in the hippocampal tissues. For assessing working memory and long-term potentiation, the double Y-maze test and Schaffer collateral-CA1 in vivo electrophysiological recording were performed, respectively Our results showed that curcumin and hesperidin decreased TNF-α, IL-10, and TLR4 protein expression and reversed memory dysfunction. However, they did not provoke a significant effect on GSH content or amplitude and slope of recorded fEPSPs in the hippocampus. In addition, curcumin, but not hesperidin, decreased interleukin-1β (IL-1β) and MDA levels. These findings imply that curcumin and hesperidin induced significant protective effects on febrile seizures, possibly via their anti-inflammatory and antioxidant properties and downregulation of TLR4.

Ameliorating effects of curcumin-loaded superparamagnetic iron oxide nanoparticles (SPIONs) on the mouse testis exposed to the transient hyperthermia: A molecular and stereological study.
    Acta histochemica, 2020, Volume: 122, Issue:8

    Testicular hyperthermia can have negative effects on male fertility. Despite reported therapeutic benefits of curcumin, several factors often limit its application such as low water solubility and instable structure. Curcumin-loaded superparamagnetic iron oxide nanoparticles (SPIONs) were designed to solve its limitation of use. In the present study, we evaluated the effect of curcumin-loaded SPIONs on transient testicular hyperthermia in mouse.. A total of 18 adult male NMRI mice were divided into three groups (n = 6): I. Controls (Cont), II. Scrotal hyperthermia (Hyp), III. Scrotal hyperthermia + curcumin-loaded iron particles (240 μL) (Hyp + Cur). After seventy days, the animals were sacrificed and used for further molecular and stereological evaluations.. Sperm count, motility and viability significantly decreased in group hyp as compared to cont group. Furthermore, Sperm DNA fragmentation and cell apoptosis in testes increased remarkably in group hyp, compared with group cont. Stereological study showed a reduction in number of spermatogenic and Leydig cells, as well as reduced weight and volume of testes in hyp group. Degenerative appearance of testes exposed to hyperthermia was also observed. In addition, higher mRNA expression of inflammatory cytokines (IL1-α, IL6, and TNF-α) was detected in group hyp compared to cont group. However, curcumin-loaded SPIONs alleviated all of the pathologic changes in the Hyp + Cur group compared to the hyp group.. Here, we used nanoparticle form of curcumin in testicular hyperthermia model and showed its ameliorating effects on testes damages caused by heat stress, which can be an appropriate method to overcome the problems that limit curcumin application in cases with increased intra testicular temperature.
