Anti-urolithiatic Activity of Daidzin in Ethylene Glycol-Induced Urolithiasis in Rats.
Urolithiasis is a common urological disorder, which causes considerable morbidity in both genders at all age groups worldwide. Though treatment options such as diuretics and non-invasive techniques to disintegrate the deposits are available, but often they are found less effective in the clinics. In this work, we planned to investigate the ameliorative effects of daidzin against the ethylene glycol (EG)-induced urolithiasis in rats. The male albino rats were distributed into four groups (n = 6) as control (group I), urolithiasis induced by the administration of 0.75% EG (group II), urolithiasis induced rats treated with 50 mg/kg of daidzin (group III), and urolithiasis rats treated with standard drug 750 mg/kg of cystone (group IV). The urine volume, pH, and total protein in the urine were assessed. The activities of marker enzymes in both plasma and kidney tissues were analyzed using assay kits. The levels of kidney function markers such as calcium, oxalate, urea, creatinine, uric acid, magnesium, BUN, and phosphorous were estimated using assay kits. The status of antioxidants and inflammatory cytokines were also examined using kits. The renal tissues were examined by histopathological analysis. Our results revealed that the daidzin treatment effectively decreased the urine pH and protein level and increased the urine volume in the urolithiasis rats. Daidzin decreased the calcium, oxalate, uric acid, and urea, creatinine, and BUN levels and also improved the magnesium and phosphorus in the urolithiasis rats. The activities of AST, ALT, ALP, GGT, and LDH were effectively reduced by the daidzin in both serum and renal tissue. Daidzin also reduced the inflammatory marker and increased the antioxidant levels. Histopathology results also proved the therapeutic effects of daidzin. Together, our results displayed that daidzin is effective in the amelioration of EG-induced urolithiasis in rats.

In vivo investigation of the inhibitory effect of Peganum harmala L. and its major alkaloids on ethylene glycol-induced urolithiasis in rats.
Peganum harmala L. is a traditional medicinal plant used for centuries in folk medicine. It has a wide array of therapeutic attributes, which include hypoglycemic, sedative, anti-inflammatory, and antioxidant properties. The fruit decoction of this plant was claimed by Avicenna as traditional therapy for urolithiasis. Also, P. harmala seed showed a clinical reduction in kidney stone number and size in patients with urolithiasis.
In light of the above-mentioned data, the anti-urolithiatic activities of the seed extracts and the major β-carboline alkaloids of P. harmala were investigated.
Extraction, isolation, and characterization of the major alkaloids were performed using different chromatographic and spectral techniques. The in vivo anti-urolithiatic action was evaluated using ethylene glycol (EG)-induced urolithiasis in rats by studying their mitigating effects on the antioxidant machinery, serum toxicity markers (i.e. nitrogenous waste, such as blood urea nitrogen, uric acid, urea, and creatinine), minerals (such as Ca, Mg, P, and oxalate), kidney injury marker 1 (KIM-1), and urinary markers (i.e. urine pH and urine output).
Two major alkaloids, harmine (P1) and harmalacidine HCl (P2), were isolated and in vivo evaluated alongside the different extracts. The results showed that P. harmala and its constituents/fractions significantly reduced oxidative stress at 50 mg/kg body weight, p.o., as demonstrated by increased levels of glutathione (GSH), glutathione reductase (GR), glutathione peroxidase (GPx), and catalase (CAT) in kidney homogenate as compared to the EG-treated group. Likewise, the total extract, pet. ether fraction, n-butanol fraction, and P1, P2 alleviated malondialdehyde (MDA) as compared to the EG-treated group. Serum toxicity markers like blood urea nitrogen (BUN), creatinine, uric acid, urea, kidney injury molecule-1 (Kim-1), calcium, magnesium, phosphate, and oxalate levels were decreased by total extract, pet. ether fraction, n-butanol fraction, P1, and P2 as compared to the EG-treated group. Inflammatory markers like NFκ-B and TNF-α were also downregulated in the kidney homogenate of treatment groups as compared to the EG-treated group. Moreover, urine output and urine pH were significantly increased in treatment groups as compared to the EG-treated group deciphering anti-urolithiatic property of P. harmala. Histopathological assessment by different staining patterns also supported the previous findings and indicated that treatment with P. harmala caused a gradual recovery in damaged glomeruli, medulla, interstitial spaces and tubules, and brown calculi materials as compared to the EG-treated group.
The current research represents scientific evidence on the use of P. harmala and its major alkaloids as an effective therapy in the prevention and management of urolithiasis.

Anti-urolithiatic effects of Punica granatum in male rats.
The traditional use of Punica granatum has been reported to regulate urine discharge and controls the burning sensation of urine.
Animals model of calcium oxalate urolithiasis was developed in male rats by adding ethylene glycol 0.75% in drinking water. The Punica granatum chloroform extract (PGCE) and Punica grantum methanol extract (PGME) orally at 100, 200 and 400mg/kg, respectively, were administered along with ethylene glycol for 28 days. On 28 day, 24h urine was collected from individual rats and used for estimation of urine calcium, phosphate and oxalate. The serum creatinine, urea and uric acid levels were estimated in each animal. The kidney homogenate was used for the estimation of renal oxalate contents. The paraffin kidney sections were prepared to observe the CaOx deposits.
The ethylene glycol control (Gr.-II) had significant (P<0.001 vs. normal) increase in levels of urine oxalate, calcium and phosphate, serum creatinine, urea and uric acid and renal tissues oxalates, as compared to normal (Gr.-I). The paraffin kidney sections show significant histopathological changes. The treatment of PGCE and PGME at 100, 200 and 400mg/kg doses, significantly (P<0.001 vs. control) decreased the urine oxalate, calcium and phosphate, renal tissue oxalates and serum creatinine, urea and uric acid, in EG induced urolithiasis after 28 days.
The PGCE and PGME at the doses of 400mg/kg, found to be more effective in decreasing the urolithiasis and regeneration of renal tissues in male rats.

Chenopodium album Linn. leaves prevent ethylene glycol-induced urolithiasis in rats.
The leaves of Chenopodium album Linn. are traditionally used for correction of kidney diseases and urinary stones. The present work investigated the effect of methanolic and aqueous extracts of leaves of Chenopodium album on experimentally-induced urolithiasis in rats to substantiate its traditional use as antilithiatic agent.
The leaf extract was standardized by HPLC. Urolithiasis was induced in rats by administration of 0.75% v/v of ethylene glycol (EG) in distilled water and in addition, vehicle or methanol (CAME) or aqueous (CAAE) extract of the leaves of Chenopodium album each in the dose 100, 200 and 400mg/kg or Cystone (750mg/kg) were administered daily orally for 28 days. Urolithiasis was assessed by estimating the calcium, phosphorus, urea, uric acid, and creatinine in both urine and plasma. The volume, pH and oxalate levels were also estimated in urine. The renal oxalate content was estimated in kidney while calcium oxalate deposits were observed histologically.
The treatment with CAME or CAAE for 28 days significantly attenuated the EG-induced elevations in the urine and plasma levels of calcium, phosphorus, urea, uric acid and creatinine along with decrease in urine volume, pH and oxalates. The treatments also decreased renal tissue oxalate and deposition of oxalate crystals in kidney due to EG treatment. The effects of CAME and CAAE were comparable to standard antilithiatic agent, cystone. The findings indicate the preventive effect of CAME and CAAE which can be due to inhibitory effect on crystallization and stone dissolution. The effect was attributed to the presence of phytochemicals like flavonoids and saponins.
In conclusion, Chenopodium album leaves exhibited antilithiatic effect and validates its ethnomedicinal use in urinary disorders and kidney stones.
