“…Spontaneous alternation behaviour (SAB) is based on the fact that rodents prefer to visit the less recently visited arm, thus implicating that it will need to recall which was the last arm visited. The percentage alternation was calculated as reported by Sivakumar et al, (2017).…”

This study examines the effect of gestational administration of aqueous leaf extract of Jatropha tanjorensis (JT) on postpartum-like behavioural outcomes to delineate its possibility as a prophylactic, therapeutic agent in the treatment of postpartum symptoms. Inseminated female rats (120-150g) were grouped into two-control and JT group (n=10). Control received 20 ml/kg of distilled water and JT group received 500 mg/kg of JT orally once daily for 21 days in gestation. Non-pregnant rats were excluded from the study. Parameters assessed at postpartum include antidepressant-like (force swim test, FST; tail suspension-test, TST), locomotor (open field test, OFT), anxiolytic-like (elevated plus maze, EPM; light-dark box, LDB), learning and memory (T-maze; novel object recognition task, NORT), social (nest score) and analgesic-like (hot plate test, HPT; tail flick test, TFT) behaviours. JT increased (P<0.05) mobility and latency to immobility durations in FST and TST; open arm entry (P<0.001) and duration (P<0.01) in EPM and light box duration (P<0.05) in LDB; locomotion and exploration, but reduced anxiety-like levels in EPM, LDB and OFT. It increased nest score (P<0.05); mean retraction time (P<0.01) of TFT. JT showed positive score for short and long term memory in NORT and improved percentage alternation in T-maze though not significant compared to control. In conclusion, the aqueous extract has a therapeutic effect that reduces postpartum-like depression and anxiety, and improves locomotor activity. JT can be a preventive and adjuvant therapeutic option for pregnant women

Alzheimer’s disease (AD) is an age-related progressive disorder characterized by neurodegeneration and accumulation of abnormal proteins. Artesunate, an anti-malarial drug has recently been shown to have anti-inflammatory, antiviral, angiogenic and other pleiotropic effects. It has also improved cognitive decline induced by hepatic coma which is suggestive of its role in learning and memory. In view of this, the current study was planned to assess the effect of the combination of artesunate with rivastigmine and memantine in aluminium chloride induced neurotoxicity. The study was conducted on 24 male adult albino wistar rats which were divided into four groups (n=6). Group - I to IV received saline, aluminium chloride (AlCl3), AlCl3 + artesunate +rivastigmine, AlCl3 + artesunate + memantine for 60 days respectively. After the 60th day of treatment, all animals were subjected to a passive avoidance task. All the animals were then sacrificed to study the histopathological changes in the hippocampus. Artesunate in combination with rivastigmine and memantine showed significant improvement in memory impairment and reduced neuronal death. Neuronal viability was more prominent in combination treatments as shown by histopathological results. Artesunate in combination with rivastigmine and memantine could be useful in AD. Artesunate can be used as an adjuvant therapy because artesunate combined with standard drugs produced significant neuroprotective effect.

Objectives: The objective of this study was to investigate the effectiveness and potential protective effects of various intervention strategies, such as choline and docosahexaenoic acid (Ch-DHA) supplementation, Clitoria ternatea root extract (CTR) supplements, human embryonic kidney stem cell conditioned media (HEK-CM) treatment and exposure to enriched environments (EEs), in mitigating neural cell degeneration in dorsal hippocampal subregions of naturally ageing mice brain. Materials and Methods: Twelve–fifteen-month-old CF1 male mice were subdivided (n = 6/group) into normal age-matched control, Ch-DHA supplemented, EE exposed, HEK-CM administered and CTR-supplemented groups. Neuro morphological alterations in the dorsal hippocampus were assessed using cresyl violet staining. Results: Higher neural cell degeneration was observed in the CA1–CA3 dorsal hippocampal subregions in normal ageing mice brains. Notably, interventions such as HEK-CM administration, Ch-DHA supplementation, exposure to an EE and CTR supplementation significantly reduced degeneration, particularly in the CA3 and CA2 regions. Conclusion: Ch-DHA supplementation and HEK-CM treatment are observed to significantly reduce age-dependent degeneration of dorsal hippocampal CA3 and CA2 neurons in naturally ageing mice compared to EE exposure or CTR supplementation.
