[PMID: 33610714 DOI: 10.1016/j.jep.2021.113942] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 12/28/2020] [Accepted: 02/14/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herniaria glabra L. popularly known in Morocco as "Herras lehjer" which means "Stonebreaker" in English is a plant that has been used in traditional medicine to treat edema, water retention, urinary diseases and renal problems including kidney stones. AIM OF THE STUDY The present study aims to investigate the diuretic activity of the crude ethanol extract (CEE) and the saponin-rich extract (SRE) of the Herniaria glabra L. METHODS CEE and SRE were prepared using maceration. SRE was obtained after using the selective liquid-liquid extraction method with organic solvents. Control (normal saline, 10 ml/kg), reference drug (furosemide 10 mg/kg) and three different doses (10 mg/kg, 50 mg/kg, 200 mg/kg) of the CEE and SRE were administered orally to male Wistar rats. The diuretic activity of the extracts was determined by measuring urine volume, urinary electrolyte and urine pH. The urine output measured at 5 h and 24 h, electrolyte concentration and pH were measured at 24 h duration. Data were analyzed by one way ANOVA followed by Dunnett's t-test. RESULTS The findings indicated that the CEE significantly increased diuresis at 50 mg/kg and 200 mg/kg. Moreover, the SRE showed significant diuretic effect at all doses. CEE at a dose of 200 mg/kg increases the volume of urine by 81%, while SRE at a dose of 200 mg/kg increases the volume of urine by 114%. SRE demonstrated at 200 mg/kg the highest diuretic properties comparable to the reference drug. Na+, K+ and Cl- urinary excretion was also significantly increased at 50 mg/kg and 200 mg/kg of CEE and at all doses of SRE. HPLC analysis revealed the presence of the saponin aglycones, the main ones are medicagenic acid and oleanolic acid, their content in CEE 3.1 ± 0.4%, 2.4 ± 0.3% respectively and in SRE 7.9 ± 0.2%, 5.9 ± 0.3% respectively. Triterpenoid saponins could be responsible for the diuretic activity of Herniaria glabra. CONCLUSION This study could make it useful to develop a pharmaceutical product based on purified saponin-rich extract of Herniaria glabra L. as a diuretic agent.

Abstract
OBJECTIVE The present study has been carried out to evaluate the diuretic and antioxidant properties of pine herb in an animal model. MATERIALS AND METHODS 45 adult male rats were randomly divided into nine groups including: groups I (the negative control), groups II (positive control, furosemide 10 mg/kg), groups III to VIII (treatment groups received 100, 200, 400 mg/kg of the aqueous extracts of bark and fruit) and group IX received the combination of aqueous extract of bark (100 mg/kg) and the fruit (100 mg/kg). The urine output, glomerular filtration rate (GFR), electrolytes, urea, and creatinine levels were evaluated. Furthermore, the phenolic content and antioxidant activity of both extracts were also assessed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) and Folin-Ciocalteu methods. RESULTS The aqueous extracts of the pine bark and fruit increased the urinary output in a dosedependent manner. The combination of the two extracts compared to the other extracts alone significantly increased the serum potassium level. This study also showed each extract increase creatinine clearance in a dose-dependent manner (p<0.01 and p<0.05). The increase of GFR in the combination group was not significant. The current data showed a significant increase in the total phenolic content in pine bark extract in compared with the fruit extract. CONCLUSION The pine bark and fruit can be useful in the prevention and treatment of kidney stones due to the high diuretic properties and antioxidant activity.

Abstract
Studies indicate that Syzygium spp-derived oleanolic acid (OA) enhances renal function of streptozotocin (STZ)-induced diabetic rats as evidenced by its reversal of the previously reported inability of the kidney to excrete Na(+) in these animals. We postulated that OA influences Na(+) excretion in the proximal tubule, the site where two-thirds of filtered NaCl is reabsorbed through a process mediated by transport proteins. Therefore, the study investigated the effects of OA on proximal tubular Na(+) handling in male Sprague-Dawley rats using renal lithium clearance (C(Li)). Renal C(Li) has been used widely in animal and clinical studies to assess proximal tubular function. Sub-chronic doses of OA were administered to rats twice every third day for 5 weeks. Rats treated with deionized water served as control animals. Cytotoxicity of OA on kidney and liver cell lines was assessed by the MTT and comet assays. OA increased Na(+) excretion of conscious male Sprague-Dawley rats from week 3 to week 5. By the end of the 5-week experimental period, OA treatment significantly reduced (p < 0.05) plasma creatinine concentration of STZ-induced diabetic rats with a concomitant elevation in glomerular filtration rate (GFR). Acute OA infusion was also associated with increases in fractional excretion of sodium (FE(Na)) and lithium (FE(Li)) in anesthetized rats in the absence of significant changes in GFR. The MTT assay studies demonstrated that OA increased the metabolic activity of kidney and liver cell lines. Taken together with previous observations, this study implicates the proximal tubule in OA-evoked increases in urinary Na(+) output.

Abstract
Previous observations indicate that Ficus thonningii (Blume) [Moraceae] stem-bark extracts may be useful in the control of diabetes mellitus. Accordingly, we investigated in some experimental animal paradigms the effects of F. thonningii stem-bark ethanolic extract (FTE) on renal and cardiovascular functions as complications of diabetes. Oral glucose tolerance tests were conducted in separate groups of non-diabetic and STZ-treated diabetic rats given glucose load (0.86 g x kg(-1), p.o.) after 18-h fast, followed by various FTE doses (60, 120, and 240 mg x kg(-1)). Rats treated with deionized water (3 mL x kg(-1) p.o.), or metformin (500 mg x kg(-1) p.o.) acted as untreated and treated positive controls, respectively. Blood glucose was monitored at 15-min intervals for the first hour, and hourly thereafter for 3 h. Acute effects of FTE on kidney function and mean arterial blood pressure (MAP) were investigated in anaesthetized rats challenged with hypotonic saline after a 3.5-h equilibration for 4 h of 1 h control, 1.5 h treatment, and 1.5 h recovery periods. FTE was added to the infusate during the treatment period. Chronic effects of FTE were studied in individually caged rats treated daily with FTE (120 mg x kg(-1), p.o.) for five weeks. Cytotoxicity of FTE was assessed by dye-reduction colorimetric (MTT) assay on MDBK and LLCPK1 kidney cell lines exposed for 24 h, 48 h, and 72 h to graded concentrations of the extract. Myocardial contractile performance was evaluated on rat isolated atrial muscle strips. FTE, like metformin, decreased blood glucose levels in non-diabetic and STZ-diabetic rats. Both acute and chronic FTE treatments did not affect renal function. In vitro studies demonstrated that FTE increased MDBK cell metabolic activity by an average of 15% (72 h), and LLCPK1 mirrored the controls. Acute intravenous infusion of FTE reduced the MAP from 119 +/- 1 mmHg to 98 +/- 4 mmHg. The MAP also was reduced throughout the five-week experimental study period. FTE also produced concentration-dependent, negative inotropic and chronotropic effects on rat isolated, electrically driven left-, and spontaneously beating right-, atrial muscle preparations. Our experimental findings suggest that FTE possesses reno- and cardio-protective effects in diabetes mellitus.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Orthosiphon stamineus has been used in traditional medicine for centuries especially to treat diseases of the urinary system. AIM OF THE STUDY To investigate the diuretic activity, to elucidate its possible mechanism and to evaluate the renal effects of Orthosiphon stamineus extract. MATERIALS AND METHODS Water extracts were administered orally at doses of 5 and 10 mg/kg to Sprague-Dawley rats and the control groups were given commercial diuretic drugs either furosemide or hydrochlorthiazide at 10 mg/kg. Urine volume, urine pH, urine density and urine electrolytes were determined every hour for 4h. Blood was assayed for glucose, albumin, blood urea nitrogen (BUN) and creatinine. RESULTS O. stamineus extract exhibited dose-dependent diuretic activity. However, excretion of Na+ and Cl(-) was not markedly elevated, but urinary excretion of K+ was significantly increased. O. stamineus extracts slightly increased the serum BUN, creatinine and blood glucose level. Although these levels were statistically significant when compared to control, these levels were still within normal range. CONCLUSIONS O. stamineus exhibited diuretic activity, but was less potent than furosemide and hydrochlorothiazide. Care should be taken when consuming this herb as slight increase of kidney function enzymes was recorded.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ampelozizyphus amazonicus Ducke is a plant used in Brazilian folk medicine to both prevent malaria and act as a depurative. AIM OF THE STUDY We have investigated the effects of an ethanol crude extract of roots of Ampelozizyphus amazonicus (CEAaD), a chemically characterized saponin mixture (SAPAaD), as well as a saponin-free fraction (SAPAaD-free) obtained from CEAaD on diuresis in rats. MATERIALS AND METHODS Wistar rats under ad libitum water conditions or water deprivation for 12h prior to the start of the experiment were volume-expanded with 0.9% NaCl (4% body weight, by gavage) containing either CEAaD, SAPAaD, or SAPAaD-free at the doses indicated in the text. Rats were individually housed in metabolic cages, and urine volume was measured every 30 min throughout the experiment (3 h). RESULTS CEAaD increased urine volume in rats under conditions of both free access to water and under water deprivation. In the latter condition, CEAaD (150 mg/kg) increased the urine volume from zero to 0.9+/-0.1 ml/120 min, n=6). Similarly, the SAPAaD-free (50-200 mg/kg) mixture also increased the urine volume. In contrast, SAPAaD (12.5-1000 mg/kg) produced a significant reduction (p<0.01) in diuresis under conditions of both water deprivation and with free access to water prior to the start of the experiment. CONCLUSION Our data indicate that CEAaD contains compounds that cause both diuresis and antidiuresis and that the antidiuretic effect is due mainly to the presence of saponins.

Abstract
The present study was undertaken in normotensive anaesthetized male rats that received a continuous perfusion of a chrysin glucoside isolated from the flowers and leaves of Calycotome villosa subsp intermedia at a dose of 2.5 mg/kg, or furosemide (control diuretic) at a dose of 0.5 mg/kg. Compared with the control rats receiving NaCl (0.9%), the urine flow, glomerular filtration and electrolyte excretion (Na+, K+) increased significantly in rats treated with chrysin glucoside (p < 0.001). A similar effect was observed in the rats perfused with furosemide. Intravenous injections of bolus doses (1-3 mg/kg) of the chrysin glucoside to anaesthetized rats elicited an immediate and dose-dependent decrease in mean arterial blood pressure (MABP). Pretreatment of the rats with the nitric oxide synthase inhibitor, l-NOArg (10 mg/kg), reduced partially, but significantly (p < 0.01), the maximal decrease in MABP elicited by chrysin glucoside. In the rat isolated aorta preparation, chrysin glucoside (10-100 microm) inhibited in a concentration-dependent manner the noradrenaline (1 microm) induced contractions (IC(50) = 52 microm). This relaxant activity of chrysin glucoside was significantly reduced by incubation of the endothelium-intact rings with l-NOArg (100 microm), (80 +/- 4.7% vs 48 +/- 5.06% in the absence of L-NOArg). In conclusion, these results demonstrate a diuretic and hypotensive action of a chrysin glucoside from Calycotome villosa in anaesthetized rats and indicating an action on renal function, and an active vascular relaxation mediated partially through nitric oxide release.

Abstract
AIM OF THE STUDY The present investigation was carried out to evaluate the acute diuretic activity of continuous intravenous infusion of an aqueous extract of the seed of Coriandrum sativum L. Apiaceae (coriander) in rats. MATERIALS AND METHODS The aqueous extract of coriander seed was administered by continuous intravenous infusion (120 min) at two doses (40 and 100mg/kg) to anesthetized Wistar rats. Furosemide (10mg/kg), a standard diuretic was used as the reference drug. Excretion of water and electrolytes (sodium, potassium and chloride) in urine was measured, and glomerular filtration rate (equal to creatinine clearance) was determined. RESULTS The crude aqueous extract of coriander seeds increased diuresis, excretion of electrolytes, and glomerular filtration rate in a dose-dependent way; furosemide was more potent as a diuretic and saluretic. The mechanism of action of the plant extract appears to be similar to that of furosemide. CONCLUSIONS The aqueous extract of coriander seed possesses diuretic and saluretic activity, thus, validating the use of coriander as a diuretic plant in Moroccan pharmacopoeia.

Abstract
There is increasing interest in the health and wellness benefits of herbs and botanicals. This is with good reason as they might offer a natural safeguard against the development of certain conditions and be a putative treatment for some diseases. One such area may be the lowering of blood pressure in those where it is elevated (i.e., hypertension). One class of clinical medicines used to lower blood pressure are known as diuretics and work by increasing the excretion of urine from the body as well as the amount of sodium in urine. There are a growing number of studies purporting diuretic effects with traditional medicines. The aim of this article was to review these studies and identify which extracts promote diuresis (which we assessed on terms of urine excreted and urinary sodium excretion) and also to identify the research needs in this area. We identified a number of species and genuses reporting diuretic effects. Of these, the most promising, at the present time, are the species Foeniculum vulgare, Fraxinus excelsior, Hibiscus sabdariffa, Petroselinum sativum and Spergularia purpurea, and species from the genuses Cucumis (Cucumis melo and Cucumis trigonus), Equisetum (Equisetum bogotense, Equisetum fluviatile, Equisetum giganteum, Equisetum hiemale var. affine and Equisetum myriochaetum), Lepidium (Lepidium latifolium and Lepidium sativum), Phyllanthus (Phyllanthus amarus, Phyllanthus corcovadensis and Phyllanthus sellowianus) and Sambucus (Sambucus mexicana and Sambucus nigra). However, there the number of studies is limited and we recommend that further studies be conducted to confirm reported effects. Such evidence is needed to provide scientific credence to the folklore use of traditional medicines and even be helpful in the development of future medicines, treatments and treatment guidelines.

Abstract
The purpose of this study was to examine the acute diuretic effect of the water extract of the aerial parts of Retama raetam (RR) at a dose of 5 mg/kg/h in normal rats. The aqueous extract was administered intravenously and the diuresis was followed within 4 h after starting the treatment. Intravenous administration of the aqueous RR extract produced a significant increment on diuresis from the second hour (p<0.01) to the fourth hour (p<0.001). Furosemide at a dose of 0.1 mg/kg/h had a similar effect when compared to RR administration. Parallel, the noticed increase of diuresis was associated with an elevation of glomerular filtration rate (p<0.05) and a significant decrease of urinary osmolarity (p<0.001). However, RR extract did not affect plasma urea levels, urine pH, plasma osmolarity and hematocrite. It is then concluded that the water extract of the aerial parts of RR exhibited a significant diuretic effect in normal rat.

Abstract
The purpose of this study was to examine the chronic diuretic effect of the water extract of the whole plant of Spergularia purpurea (SP) at different doses (100, 200 and 400 mg/kg) in normal rats. Daily oral administration of the water extract was tested for 4 weeks. Urinary water and electrolytes excretion were determined weekly. Oral administration of the water extract at different doses produced a significant and dose-dependent diuresis and increase in electrolytes excretion. The highest dose (400 mg/kg) of the water extract of SP enhanced urine output from 7.15 +/- 0.42 ml/24 h at the start to 23.01 +/- 0.75 ml/24 h after 4 weeks (p < 0.001). It also produced significant increase in urinary excretion of Na+ (P < 0.01), K+ (P < 0.01) and Cl(-) (P < 0.01). Chronic treatment with SP decreased significantly urine osmolality (P < 0.01 vs. control), while a slight increase in glomerular filtration rate was also observed (P < 0.05) for both doses of water extract (100 and 400 mg/kg). It is concluded that the water extract of whole plant of SP has a significant diuretic effect in rats.
