The objective was to investigate the anti-urolithiatic effect of ethanolic extract of Cassia auriculate on ethylene glycol (EG) induced urolithiasis in experimental rats. The animals were divided into five groups of six animals each. Except the normal group all the other groups received ethylene glycol 0.75% and Ammonium chloride 1% v/v in water induce orally for 28 days. Normal groups received plain water orally. The standard group received cystone 750mg/kg b.w orally. Test groups received EECA 200mg/kg and 400mg/kg b.w orally. On the 28th day, blood and urine samples were collected and used for estimation of biochemical parameters such as calcium, phosphates, oxalates, creatinine, uric acid, SOD, and CAT followed by histopathological studies. Treatment with EECA was found to exert dose dependent anti urolithiatic action. Increased urine volume in EECA treated groups as compared to diseased group was indicative of diuretic property. Elevated calcium, phosphate and oxalate levels in diseased group animals were found to be decreased in animals treated with EECA. Increased levels of serum calcium, creatinine and uric acid were considerably brought down towards normal values in proportion to EECA doses administered. Antioxidant parameters like SOD and CAT were decreased along with significant increase in MDA levels which is the main product of lipid peroxidation in EG treated rats. However the rats treated with EECA showed significant improvement in these parameters. Hence it is concluded that the ethanolic extract of Cassia auriculata possess anti-urolithiatic activity.

Abstract. Uricase-deficient mice develop uric acid nephropathy, with high mortality rates before weaning. Urate excretion was quantitated and renal function was better defined in this study, to facilitate the use of these mice as a model for evaluating poly(ethylene glycol)-modified recombinant mammalian uricases (PEG-uricase) as a potential therapy for gout and uric acid nephropathy. The uric acid/creatinine ratio in the urine of uricase-deficient mice ranges from 10 to >30; on a weight basis, these mice excrete 20- to 40-fold more urate than do human subjects. These mice consistently develop a severe defect in renal concentrating ability, resulting in an approximately sixfold greater urine volume and a fivefold greater fluid requirement, compared with normal mice. This nephrogenic diabetes insipidus leads to dehydration and death of nursing mice but, with adequate water replacement, high urine flow protects adults from progressive renal damage. Treatment of uricase-deficient mice with PEG-uricase markedly reduced urate levels and, when initiated before weaning, preserved the renal architecture (as evaluated by magnetic resonance micros-copy) and prevented the loss of renal concentrating function. PEG-uricase was far more effective and less immunogenic than unmodified uricase. Retention of uricase in most mammals and its loss in humans and some other primates may reflect the evolution of renal function under different environmental conditions. PEG-uricase could provide an effective therapy for uric acid nephropathy and refractory gout in human patients.

The objective of our research is to investigate the antiurolithiatic intervention of bioactive compounds of Asparagus racemosus loaded Chitosan nanoparticles (BACARNPs) on ethylene glycol engendered renal calculi in male Wister rats. The efficiency of bioactive compounds of A. racemosus (BACAR) at 800 mg/kg p.o and BACARNPs at 800 mg equivalent weight of BACAR/kg p.o was validated in ethylene glycol 0.75% (v/v) and ammonium chloride 1% (w/v) mediated renal calculi in rats. Cystone (750 mg/kg, p.o.) has been used as a standard drug. Urinary variables comprise calcium, magnesium, oxalate, phosphate, uric acid, creatinine, urine pH, urine volume, and Creatinine clearance; Serum parameters include creatinine, blood urea nitrogen (BUN), calcium and uric acid; calcium and oxalate deposition in the kidney were assessed. In vivo antioxidant parameters include lipid peroxidation, superoxide dismutase, catalase, and glutathione were determined and histopathological studies were also examined. In both control groups, a substantial increase in urinary excretion of calcium, oxalate, and their intensification in the kidney; enhanced amounts of phosphate, uric acid, and reduced magnesium levels in urine; elevated serum creatinine, BUN, calcium and uric acid; Creatinine clearance was declined were observed and normalized in treated groups. In vivo antioxidant parameters and histopathological variations reinstated to conventional form. Chitosan serves as a ligand to renal epithelial cells leads to improved agglomeration of BACAR in kidney compared to BACAR administered solitarily results in increased antiurolithiatic activity.

Introduction: Both watermelon and Persian melon extracts have various pharmacological properties like anti-diabetic, anti-viral, anti-cancer, and anti-urolithiasis effects. Objectives: The present study was conducted to investigate the effects of hydroalcoholic extracts of watermelon and Persian melon rind on kidney stone prevention in male Wistar rats. Materials and Methods: Fifty-six Wister rats were randomly divided into seven groups and treated for 28 days. The first group (healthy control) and the second group (negative control) received drinking water and water containing 1% ethylene glycol, respectively. The third and fourth groups, received 100 mg/kg/d hydroalcoholic extract of watermelon rind and Persian melon rind, respectively in addition to 1% ethylene glycol. The fifth and sixth groups, received 400 mg/kg/d hydroalcoholic extract of watermelon rind and Persian melon rind, respectively in addition to 1% ethylene glycol. The seventh group received 0.5 mEq/kg/d potassium citrate in addition to 1% ethylene glycol for prevention and treatment of kidney stone. A 24-hour urine collection was conducted to determine the levels of sodium, calcium, uric acid, oxalate and citrate concentration. Histological study of calcium oxalate crystals was also performed. The serum levels of urea, creatinine, uric acid, calcium, phosphorus, magnesium, SGPT (serum glutamic-pyruvic transaminase), SGOT (serum glutamic-oxaloacetic transaminase), total antioxidant capacity, and malondialdehyde (MDA) of blood were determined accordingly. Results: In the present study, administration of high-dose extract of watermelon and Persian melon rind (400 mg/kg/d) and potassium citrate showed significant changes in variables of sodium, calcium, uric acid, citrate, urine volume (P<0.01), blood creatinine, blood uric acid, blood calcium, and serum SGPT (P<0.05). The histological study of calcium oxalate crystals showed a significant reduction in oxalate levels in all prevention groups. Conclusion: The extracts of watermelon and Persian melon rind are effective in preventing calcium oxalate stones by decreasing the levels of oxalate, sodium, and calcium and increasing citrate levels and urine volume and affecting the total antioxidant capacity. Persian melon rind extract was more effective than potassium citrate and watermelon rind extract in reducing urine sodium. High-dose watermelon rind extract showed similar effects as potassium citrate.

Since ancient times plant as sources of medicinal compounds have continued to play a dominant role in the maintenance of human health. To treat chronic and infectious diseases plants used in traditional medicine contain a wide range of ingredients. In this regard, Cassia auriculata L. (Caesalpiniaceae) is widely used in Ayurvedic medicine as a tonic, astringent and as a remedy for diabetes, conjunctivitis, ulcers, leprosy, skin and liver diseases. The aim of present study was to evaluate the antimicrobial activity of ethanolic extract of Cassia auriculata leaves and flowers (CALE & CAFE). CALE and CAFE exhibited broad spectrum antimicrobial activity against standard strains of Staphylococcus aureus, Escherichia coli and Bacillus subtilis and exhibited no antifungal activity against standard strains of Candida albicans and Aspergillus niger. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) was carried out for CALE and CAFE. The results obtained in the present study indicate that the CALE and CAFE can be a potential source of natural antimicrobial agents.

Nephrolithiasis is a highly prevalent condition, but its incidence varies depending on race, gender, and geographic location. Approximately half of patients form at least one recurrent stone within 10 years of the first episode. Renal stones are usually composed of calcium salts (calcium oxalate monohydrate or dihydrate, calcium phosphate), uric acid, or, less frequently, cystine and struvite (magnesium, ammonium, and phosphate). Calcium oxalate stones, the most commonly encountered ones, may result from urinary calcium oxalate precipitation on the Randall plaque, which is a hydroxyapatite deposit in the interstitium of the kidney medulla. Uric acid nephrolithiasis, which is common among patients with metabolic syndrome or diabetes mellitus, is caused by an excessively acidic urinary pH as a renal manifestation of insulin resistance. The medical evaluation of the kidney stone patient must be focused on identifying anatomic abnormalities of the urinary tract, associated systemic diseases, use of lithogenic drugs or supplements, and, mostly, urinary risk factors such as low urine volume, hypercalciuria, hyperuricosuria, hypocitraturia, hyperoxaluria, and abnormalities in urine pH that can be affected by dietary habits, environmental factors, and genetic traits. Metabolic evaluation requires a urinalysis, stone analysis (if available), serum chemistry, and urinary parameters, preferably obtained by two nonconsecutive 24-hour urine collections under a random diet. Targeted medication and dietary advice are effective to reduce the risk of recurrence. Clinical, radiologic, and laboratory follow-ups are needed to prevent stone growth and new stone formation, to assess treatment adherence or effectiveness to dietary recommendations, and to allow adjustment of pharmacologic treatment.

Abstract Background Glyphae brevis leaf is reported in ethnomedicine as a treatment for hepatitis and jaundice; however, no studies have hitherto investigated the mechanistic basis of these claims. Methods A hepato-protective role of G. brevis hydromethanolic (GBH) leaf extract was established against carbon tetrachloride (CCl4)-induced hepatotoxicity. Twenty-four hours after a CCl4 challenge, rats were sacrificed and serum hematological indices, lipid profile, and biochemical parameters were determined. The antioxidant enzymes parameters (glutathione, catalase, and superoxide dismutase) and lipid peroxidation product (thiobarbituric reactive substances) levels in liver homogenates were evaluated. Changes in the liver cyto-architecture of different treatment groups were also investigated. Results The GBH extract produced no significant impact on weight and hematological indices. Intoxication with CCl4 significantly (p<0.001–0.05) increased total cholesterol (TC) and low-density lipoproteins (LDL) compared with control rats. Pretreatment with GBH leaf extract significantly reduced triglycerides, TC, and LDL to approaching control levels (p<0.001–0.05). The GBH leaf extract significantly alleviated CCl4-induced elevation of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and the CCl4-induced depression of total protein, and albumin. Liver antioxidant parameters were significantly increased in plant extract-treated rats, and this antagonized the pro-oxidant effect of CCl4. Histopathological studies also supported a hepato-protective effect of GBH. Collectively, the GBH leaf extract alleviated the CCl4-induced hepatotoxicity through improvement of innate antioxidant enzyme levels and lipid metabolism and stabilized the hepatocyte cyto-architecture of intoxicated rats. Conclusions This study establishes the ethnomedicinal role of G. brevis leaf in hepatitis and the mechanistic basis of hepato-protection against CCl4-induced hepatotoxicity.

Adhesion of microcrystals that nucleate in tubular fluid to the apical surface of renal tubular cells could be a critical step in the formation of kidney stones, 12% of which contain uric acid (UA) either alone or admixed with calcium oxalates or calcium phosphates. UA crystals bind rapidly to monolayer cultures of monkey kidney epithelial cells (BSC-1 line), used to model the surface of the nephron, in a concentration-dependent manner. The urinary glycoproteins osteopontin, nephrocalcin, and Tamm-Horsfall glycoprotein had no effect on binding of UA crystals to the cell surface, whereas other polyanions including specific glycosaminoglycans blocked UA crystal adhesion. Specific polycations also inhibited adhesion of UA crystals and appeared to exert their inhibitory effect by coating cells. However, removal of anionic cell surface molecules with neuraminidase, heparitinase I, or chondroitinase ABC each increased UA crystal binding, and sialic acid-binding lectins had no effect. These observations suggest that hydrogen bonding and hydrophobic interactions play a major role in adhesion of electrostatically neutral UA crystals to renal cells, unlike the interaction of calcium-containing crystals with negatively charged molecules on the apical cell surface via ionic forces. After adhesion to the plasma membrane, subsequent cellular events could contribute to UA crystal retention in the kidney and the development of UA or mixed calcium and UA calculi.
