Abstract
Scorpion venom is a complex mixture of peptides and proteins, rich in toxins. Its toxicological effects are related to central disruptions and autonomic disturbances, organ failure, as well as an excessive systemic inflammatory response. Since the role of the hypothalamic pituitary adrenal (HPA) axis is central in the neuroendocrine-immunological axis, the purpose of this study was, therefore, to examine the immunotoxic effect of Androctonus australis hector (Aah) venom on HPA-axis in synchronised-mice model. Taking into account the circadian activity of the HPA-axis, the variations of adrenocorticotropic hormone and corticosterone plasma levels, oxidative stress as well as inflammatory markers in cerebral, hypothalamic and adrenal tissue homogenates were investigated during the rest and activity phases of animals. Histopathology study was also performed. Results showed that Aah venom activated the HPA axis. This response seems to be dependent on time of envenomation, as a higher hormone levels were more operative during the active phase than in the rest phase when compared to time-matched control. The local toxicity-effects following Aah envenomation revealed an imbalance in oxidative stress with a higher antioxidant defences in darkness hypothalamic and cerebral tissues. Furthermore, there were significantly higher levels in vascular permeability in hypothalamic and cerebral tissues accompanied by a concomitant increase in immune-cell infiltration and/or activation as shown by expression of CD68 and myeloperoxidase activity during the active phase compared with the rest phase. Overall results suggested that Aah venom had a toxic impact on different HPA-axis areas and the effect varies according to the time of envenomation.

Abstract
Valproic acid (VPA) is currently one of the most commonly used antiepileptic drugs. This study aims to investigate whether VPA pharmacokinetics varied according to circadian dosing-time. A single dose of VPA (350 mgkg(-1)) was administered by intraperitonally (i.p.) route to a total of 132 mice synchronized for 3 weeks to 12h light (rest span) and 12 h dark (activity span). Four different circadian times (1, 7, 13 and 19 HALO) of drug injection were used (33 mice/circadian time). At each circadian time, blood samples were withdrawn at (0 h) and at 0.083, 0.166, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2 and 3h after VPA injection. Plasma VPA concentrations were determined by an EMIT method. There were no significant differences in T(max) of VPA whatever the circadian-time of injections (T(max)=0.166 h). However, there were relevant differences in C(max) between the four circadian groups (p<0.005), it varied between 386 ± 30.86 mg L(-1) in mice treated at 7 HALO and 824 ± 39.85 mg L(-1) in mice treated at 19 HALO. The AUC(0-∞) was significantly two times higher when VPA was administered at 19 HALO as compared to the injection at 7 HALO. Drug dosing at 7 HALO resulted in highest Cl(T) value: 0.405 ± 0.006 L h(-1)kg(-1), whereas Cl(T) was significantly slower when VPA was administered at 19 HALO (0.157 ± 0.009 L h(-1)kg(-1)) (p<0.0001). The AUC(0-∞) was significantly 2-fold higher when VPA was administered at 19 HALO (2216.65 ± 138.91 mg h(-1)L(-1)) as compared to the injection at 7 HALO (864.09 ± 16.82 mg h(-1)L(-1)) (p<0.0001). Cosinor analysis showed circadian rhythm in different pharmacokinetic parameters. C(max) and AUC(0-∞) have a significant circadian rhythm with an acrophase located at 20.16 HALO ± 0.16 h (the middle of the active span) (p<0.001), whereas Cl(T) and Vd showed a significant circadian rhythm with an acrophase located respectively at 7.86 HALO ± 0.57 h and 6.13 HALO ± 0.07 h (the middle of the rest span) (p<0.001). The large circadian variation of VPA pharmacokinetic processes might be involved in the mechanisms of circadian rhythm in murine toxicity since the optimal tolerance corresponded to the time which induces lowest C(max) and AUC values.

Abstract
Background Valproic acid (VPA) is an antiepileptic drug widely used for the treatment of absence seizures and generalized tonic-clonic seizures. The present work aims to study whether VPA-induced toxicity varies according to the dosing-time in the 24 hour-scale. Methods The influence of dosing-time on tolerance to VPA was investigated in 120 male Swiss mice synchronized under a light-dark cycle (12:12). The mean VPA lethal dose was first determined to be 850 ± 0.2 mg/kg, i.p.. Such a dose was administered by i.p. route to a total of 90 mice divided in six circadian stages [1, 5, 9, 13, 17 and 21 Hours After Light Onset (HALO)] (15 mice/circadian time); 30 mice were used as control (5 mice / circadian time). Results The surviving treated mice exhibited a significant circadian variation in rectal temperature and body weight loss (p < 0.001). The least rectal temperature change and body weight loss occurred when VPA was injected at 9 HALO. Drug dosing at 9 HALO resulted in -9 % weight loss whereas drug dosing at 17 HALO was -15 % (Ø = 20.3 HALO ± 1.1 h, p ≤ 0.0001). Lethal toxicity also varied according to circadian dosing-time (χ2 = 42.1, p < 0.0001). The highest (60 %) and the lowest (6.67 %) survival rates were observed at 9 HALO and 17 HALO respectively. Cosinor analyses validated a significant circadian rhythm in survival duration with an acrophase at 8.4 HALO ± 0.75 h (p < 0.001). Conclusions With regards to these data the optimal tolerance to VPA occurred when the drug was administered in the second half of the light-rest span of mice which is physiologically analogous to the second half of the night for human patients.

Abstract
The circadian clock controls many aspects of mammalian physiology and behaviour with a periodicity of approximately 24 h. These include the anticipation of, and adaptation to, daily environmental changes such as the light-dark cycle, temperature fluctuations and the availability of food. The toxicity of many drugs is dependent on the circadian phase at which they are administered, and recent work has begun to unravel the molecular basis for circadian variations in sensitivity to xenobiotic exposure. Between 2 and 10% of the transcriptome is expressed in a circadian manner, including many key genes associated with the metabolism and transport of xenobiotics. Furthermore, a number of xenobiotics may directly alter the expression of genes that control circadian rhythms. This review discusses the emerging evidence for the regulation of circadian rhythm genes having an important impact on molecular response to xenobiotics.
