ObjectivesAluminium is present in food preparations, antacids and many medications. It causes neurodegeneration thereby resulting in a spectrum of neurological disorders such as dementia, Alzheimer’s disease and anxiety. Bacopa monnieri (BM) is widely used in ayurvedic medicine to improve memory functions. Its anxiolytic property was investigated in this study by using elevated plus maze (EPM) and plasma corticosterone level.MethodsThirty rats were assigned into five groups. Control group received distilled water, and 0.5% tween 80, AlCl3 group received Aluminium Chloride (AlCl3), Protective groups (BM100 + AlCl3 group and BM200 + AlCl3 group) received AlCl3 and BM at two different doses, and the BM200 group received BM. The EPM experiment was performed at the end of the 4th week of oral administration of BM and AlCl3 followed by the measurement of plasma corticosterone.ResultsOral administration of AlCl3 to rats increases the levels of anxiety as seen in a decrease in the percentage of entries into the open arms of EPM, an increase in grooming frequency and defecation index. However, the rats in the protective groups shown an increase in the percentage of open arm entries and rearing frequency, and decreased grooming frequency and defecation index. AlCl3 alone treated group showed a significant increase in the plasma corticosterone levels compared to the control group. Whereas the protective groups have shown a significant decrease in the plasma corticosterone levels than the AlCl3 alone treated group.ConclusionsHence the BM has potential role in reverting the anxiogenic effect of AlCl3 in the amygdala as it is evident from the plasma corticosterone levels and the EPM parameters of different groups under study.
Variations in the branching pattern of brachial artery and abnormal course of its branches are not uncommon. The present article describes a case of bifurcation of the brachial artery into a common radial-interosseous trunk and superficial ulnar artery. The embryological basis behind the present case report could be, the radial artery establishing a connection with the axis artery just below the level of origin of ulnar artery, the posterior interosseous artery arising from the axis artery distal to the origin of the radial artery. The part of axis artery between origin of ulnar and radial artery must have developed into the common radial-interosseous trunk. The part of axis artery between origin of radial and posterior interosseous arteries develops as the common interosseous artery. The superficial position of ulnar artery could enable the surgeons in raising a free ulnar forearm flap for head and neck reconstructive surgeries.
The anatomical variations in the tributaries pattern of the axillary vein are not uncommon. In this case report, we describe three distinct findings observed in the right upper limb of a 65-year-old male cadaver: (1) a venous chiasma formed between the common brachial and basilic veins in the middle of the arm, (2) the variant course of ulnar nerve passing deep into the gap created by the chiasma, and (3) the cephalic vein terminating in the basilic vein. The knowledge of such variations could be resourceful for surgeons in avoiding neurovascular damage during basilic vein catheterization and anticipating difficulty in creating the brachio-basilic arteriovenous fistula.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
