The aspect of treatment of autistic behaviour was investigated using valproic acid rat model of pregnant female rats. Two main groups (10 male rats/group) were treated for 6 days and then divided into six subgroups. The first group of normal rats was divided into three subgroups: (A) – control group, (B) – treated with camel milk (CAM; 2 mL/p.o) and (C) – treated with leptin (1000 µg/kg i.p) twice daily. The second group of autistic rats was randomly distributed into four subgroups as follows: (D) – positive control (autistics rats), (E) – treated with CAM, (F) – treated with a moderate dose of leptin and (G) – treated with a higher dose of leptin. Autistic behaviours of male offspring were checked by grooming and elevated pulz maze tests. Valproic acid (VPA)-induced autistic rats showed severe changes in oxidative stress markers, neurotransmitters and inflammatory cytokines, besides genotoxic manifestation of expression of tumour necrosis factor (TNF)-α, Bax and caspase-3. Leptin or CAM alone showed no signs of toxicity. CAM showed pronounced improvement in control rats than control itself. Leptin or CAM treatment of autistic animals showed a significant improvement of all measured parameters and genetic expression values. The improvement was pronounced in animals treated with CAM. These results suggest that CAM is a potential therapeutic candidate for autism via regulation of inflammatory and apoptotic pathways. Leptin plays an essential role in alleviation of autistic behaviour through antioxidant effects.
