The Neuroprotective Effect of Lycopodium and Withania Somnifera on Alzheimer’s Disease Induced by Aluminum Chloride in Rats
Full text linkAlzheimer's Disease (AD) is a serious health problem worldwide and known as the most common type of neurodegenerative diseases. Lycopodium (Lyc) and Withania Somnifera (WS) contains a bio active compound that proved to restore and improve cholinergic system. The present study aimed to examine the neuroprotective potential of Lyc and WS on Aluminum Chloride induced AD in rats. Fifty female Albino rats were equally and randomly divided to five groups, ten rats in each group. The rats of the first group received distilled water and served as control. The rats from second to fifth group received AlCl3 (175mg/kg), the second groups consider as AD group, in addition to AlCl3, third group received Lyc (50mg/kg), fourth received WS (200mg/kg), fifth received both treatments. After 30 days, the Acetylcholine (Ach), Acetylcholinesterase (AchE), Butyrylcholinesterase (BchE), Amyloid beta-42 (Ab-42), Tyrosine hydroxylase (TH), and Na+/K+ATPase were evaluated. The result showed that AlCl3 significantly increased Ach, AchE, BchE, Ab-42 levels, and significantly decreased TH and Na+/K+ ATPase levels in rats model of AD. Administration of Lyc and WS to rats model of AD for 30 days showed an improvement in biochemical alteration caused by AlCl3. This study suggests that oral administration of Lyc and WS have a neuroprotective effect in AD animal model

Evaluation of the Antimicrobial Activity of American Cockroach (Periplaneta americana) Ethanolic Tissue Extract against Selected Enteric Pathogens
Full text linkGastrointestinal (GI) tract infections caused by pathogenic microorganisms have a significant role in the global increase in mortality. This issue sparked an investigation into metabolites derived from numerous organisms that may have antimicrobial property against bacterial infections. The Kirby-Bauer Disc Diffusion method was used to test the extract of the American cockroach (Periplaneta americana) against enteric bacteria. The results indicate that the ethanolic extract of P. americana exhibited antimicrobial activity against the test pathogens, with the greatest inhibitory activity against Vibrio parahaemolyticus (p = 0.00013) and Candida albicans (p = 0.000911), when compared to the antibiotic controls Rifampicin, Trimethoprim, Ofloxacin, Penicillin, and antifungal drug Nystatin. However, there was no evidence of inhibitory activity against Enterococcus faecalis, Salmonella enteritidis, and Serratia marcescens. Thus, the current findings indicate that P. americana tissue extract may have antibacterial activity against medically important pathogens
