Effect of traditionally used herb Pedalium murex L. and its active compound pedalitin on urease expression - For the management of kidney stone

Pedalium murex L. is a medicinal herb that has been used for the treatment of diseases related to kidney in the traditional system of medicine. The current study aims to study the effect of ethyl acetate extract of P. murex (EAEP) and its fractionated compound pedalitin against urease production and UreC gene expression in Proteus mirabilis. The selected reference strain Proteus mirabilis (MTCC 425) and the isolates culture of Proteus mirabilis were subjected to study the antibacterial efficacy of P. murex. Expression analysis of P. mirabilis urease gene was successfully done by QPCR. The ethyl acetate extract effectively inhibit the reference Proteus mirabilis and bacterial isolates of Proteus mirabilis in the clinical samples studied. EAEP has showed more potent activity (56.7%) against urease enzyme and pedalitin also exhibited potent activity (30.1%). Using qPCR, the expression of UreC gene of P. mirabilis was controlled by EAEP and also its bioactive compound pedalitin. The present study clearly demonstrated the potency of P. murex in controlling the growth of pathogenic P. mirabilis and to control the expression of urease enzyme production as well as to restrict the urease gene expression in P. mirabilis.

Combined efficacy of Vigna radiata (L.) R. Wilczek and Amorphophallus paeoniifolius (Dennst.) Nicolson on serum lipids in albino rats

Coronary Artery Disease (CAD) is a major killer disease throughout the world. Dyslipidemia is a major contributor to the risk of CAD. Several dietary articles traditionally used in India and other South Asian countries reduced dyslipidemia. The present study was undertaken to evaluate the combined effect of Mung bean (Vigna radiata) and Elephant foot yam (Amorphophallus paeoniifolius) on serum lipids and atherogenic indices in albino rats and to compare it with a standard drug Cholestyramine. Thirty healthy albino rats of both sexes (150-200 g) were randomized to 5 groups of 6 animals each. The grouping were done based on the following criteria: Group I: Normal Control Group, Group II: (Standard Group): Cholestyramine resin 5 mg/kg bw, Group III: (Half Dose Group): Drug powder at 540 mg/kg bw, Group IV: (Effective Dose Group): Drug powder at 1080 mg/kg bw, and Group V: (Double Dose Group): Drug powder at 2160 mg/kg bw. Lipid profile was estimated at the beginning and after 30 days of treatment. The Effective and Double doses of the drug reduced Total cholesterol along with levels of Triglycerides, Low density lipoprotein and Very low density lipoprotein levels significantly (p < 0.01) along with a significant (p < 0.01) increase in high density lipoproteins (HDL) in rats. There was also significant (p < 0.01) improvement in atherogenic indices like Castelli Risk Index I, Non HDL C/HDL, Castelli risk Index II, TG/HDL, Atherogenic coefficient and Atherogenic Index of Plasma. The combination of powdered sprouted mung bean and yam powder have excellent lipid lowering potential.
