Studies on the antidiarrhoeal activity of Aegle marmelos unripe fruit: Validating its traditional usage
<p>Abstract</p> <p>Background</p> <p><it>Aegle marmelos </it>(L.) Correa has been widely used in indigenous systems of Indian medicine due to its various medicinal properties. However, despite its traditional usage as an anti-diarrhoeal there is limited information regarding its mode of action in infectious forms of diarrhoea. Hence, we evaluated the hot aqueous extract (decoction) of dried unripe fruit pulp of <it>A. marmelos </it>for its antimicrobial activity and effect on various aspects of pathogenicity of infectious diarrhoea.</p> <p>Methods</p> <p>The decoction was assessed for its antibacterial, antigiardial and antirotaviral activities. The effect of the decoction on adherence of enteropathogenic <it>Escherichia coli </it>and invasion of enteroinvasive <it>E. coli </it>and <it>Shigella flexneri </it>to HEp-2 cells were assessed as a measure of its effect on colonization. The effect of the decoction on production of <it>E. coli </it>heat labile toxin (LT) and cholera toxin (CT) and their binding to ganglioside monosialic acid receptor (GM1) were assessed by GM1-enzyme linked immuno sorbent assay whereas its effect on production and action of <it>E. coli </it>heat stable toxin (ST) was assessed by suckling mouse assay.</p> <p>Results</p> <p>The decoction showed cidal activity against <it>Giardia </it>and rotavirus whereas viability of none of the six bacterial strains tested was affected. It significantly reduced bacterial adherence to and invasion of HEp-2 cells. The extract also affected production of CT and binding of both LT and CT to GM1. However, it had no effect on ST.</p> <p>Conclusion</p> <p>The decoction of the unripe fruit pulp of <it>A. marmelos</it>, despite having limited antimicrobial activity, affected the bacterial colonization to gut epithelium and production and action of certain enterotoxins. These observations suggest the varied possible modes of action of <it>A. marmelos </it>in infectious forms of diarrhoea thereby validating its mention in the ancient Indian texts and continued use by local communities for the treatment of diarrhoeal diseases.</p
UV–Light assisted photocatalytic activity of Activated charcoal-TiO2 nanomaterial
An activated charcoal-TiO2 Catalyst was synthesized via the precipitation method and sonication technique, and three dyes: Reactive Black 5 (RB 5), Rhodamine B (Rh B) and Napthol Blue Black (NBB) were used to assess the quality of the product under UV-Light. The nanomaterial was also characterized by High-resolution scanning electron microscopy (HR-SEM), elementary dispersive X-ray (EDX), photoluminescence spectroscopy (PL) and UV-Vis DRS. The photodegradation of the three dyes when exposed to this nanomaterial indicate the superior photocatalytic activity of RB 5 as compared to the other dyes. A mechanism is proposed for the higher activity of AC-TiO2 than that of TiO2 nanocomposite material. Overall, this nanocomposite material was found to be highly stable and reusable. The nanomaterial is also economically of very low cost

1285-1288A study
was undertaken to
evaluate the anti -lipid peroxidative
activity of an aqueous extract
of A. marmelos fruits
(AMFEt) in streptozotocin
diabetic rats
in heart and pancreas. Oral administration of
AMFEt for 30 days (125
and 250 mg
Kg-1
body weight twice daily)
produced a significant
decrease in the elevated
levels of peroxidation
products, viz.thiobarbituric
acid reactive substances and
hydroperoxides in the tissues of diabetic
rats. The
