Study of selected therapeutic potentials of Momordica charantia fruit.

M. charantia extract partitioned in different solvents was assessed for antioxidant (2, 2-diphenyl l-picrylhydrazyl), total phenolic contents (TPC), total flavonoid contents (TFC), antiglycation, alpha amylase and acetylcholinesterase inhibitory activities along with cytotoxic, thrombolytic and antibiofilm potentials. Most effective antioxidant fraction was n-hexane with TPC and TFC, highest in n-butanol and ethanol fractions, respectively. Ethyl acetate fraction showed maximum glycation and alpha amylase inhibitions and optimum acetylcholinesterase inhibition was by ethanol fraction. Fractions exhibited significant hemolytic and thrombolytic efficacies and bacterial growth restraint. The present research reveals some medicinal potency of M. charantia.

Developing antimicrobial calcium alginate fibres from neem and papaya leaves extract.

OBJECTIVE: The aim of this study was to evaluate an alternative approach to developing antimicrobial alginate fibres using plant extracts, such as those from neem and papaya leaves. METHOD: Aqueous leaves extract from neem, papaya and their hybrid combinations were used as solvent to develop sodium alginate fibres. Sodium alginate polymer containing these extracts was extruded in a calcium chloride (CaCl2) bath to develop neem (NE), papaya (PE) and their hybrid combinations-based calcium alginate fibres (H-1 to H-5). The surface morphology, spectra, liquid absorption, tensile strength and antimicrobial activity of these developed fibres were measured. RESULTS: NE fibre showed greater tensile strength than PE. The liquid absorption property of all developed fibres decreased, but showed antibacterial properties against Staphylococcus aureus and reduced bacterial growth up to 85% when compared with pure calcium alginate fibre. CONCLUSION: Neem, papaya and hybrid extract-based calcium alginate fibres have the potential to be used as wound dressings.

Antidiabetic Evaluation of Momordica charantia L Fruit Extracts.

To investigate hypoglycaemic, hypolipidaemic and pancreatic beta cell regeneration activities of Momordica charantia L fruits(MC). Alloxan induced diabetic rabbits were treated with methanolic and ethanolic MC extract. Effects of plant extracts and the drug glibenclamide on serum glucose, lipid profile and pancreatic beta cell were determined after two weeks of treatment. Serum glucose and lipid profiles were assayed by kit methods. Pancreatic tissue histopathology was performed to study pancreatic beta cells regeneration. Momordica charantia extracts produced significant hypoglycaemic effects (p < 0.05). Hypolipidaemic activity of MC was negligible. Momordica charantia supplementations were unable to normalize glucose and lipid profiles. Glibenclamide, a standard drug, not only lowered the hyperglycaemia and hyperlipidaemia but also restored the normal levels. Regeneration of pancreatic beta cells by MC extracts was minimal, with fractional improvement produced by glibenclamide. The most significant finding of the present study was a 28% reduction in hyperglycaemia by MC ethanol extracts. To determine reliable antidiabetic potentials of MC, identification of the relevant antidiabetic components and underlying mechanisms is warranted.

Effect of dietary methionine and inorganic sulfate with and without calcium supplementation, on urinary calcium excretion of guinea pigs (Cavia porcellus).

Supplementation of sodium sulfate and DL-methionine along with the standard diet to guinea pigs nearly doubled the urinary calcium in 6 weeks. This was probably due to decreased tubular reabsorption of calcium which was complexed with sulfate in the tubular lumen. A mild calcium load didn't further enhance calcium excretion in sodium sulfate supplemented group, but did so in methionine supplemented group. It may be due to methionine which might have increased the intestinal absorption of calcium. Both of these compounds increased citric acid excretion and decreased magnesium excretion.

Effect of dietary salt (NaCl) supplementation on urinary profile of guinea pigs (Cavia porcellus).

Sodium chloride supplementation (120 mg/kg of body weight/day) for 12 days increased the urinary excretion of calcium from 91.6 +/- 9.0 to 159.4 +/- 16.0 mumol/day and of sulphate from 266.8 +/- 24.5 to 1176.9 +/- 87.2 mumol/day in guinea pigs. The stone risk due to increased urinary calcium excretion could possibly be counterbalanced by increasing urinary sulphate excretion. High salt intake, thus, could not increase the risk of stone formation.
