Pericopsis laxiflora is among the medicinal plants used by the traditional practitioner in the treatment of many diseases. However, data on its diuretic power are lacking. Moreover, the effect of the preparation of traditional galenic formulations on the composition of phytocompounds and essential minerals and metals is unknown. The aim of this study was to show the effect of treatment on the phytocompounds   and minerals composition and to evaluate diuretic effect of Pericopsis laxiflora aqueous axtracts. The tube characterization reactions revealed flavonoids, sterols, terpenes, catechin tannins polyphenols and saponins in aqueous extracts. Gallic tannins  and quinones are absent, All compounds were generally present in same proportions in two aqueous extracts. Chemical analysis of all aqueous extracts by atomic absorption spectrometry (AAS) showed effect of model extraction on minerals. Copper (0.3116 mg / 100g), magnesium (260.7 mg /100 g), selenium (0.00904 mg /100 g), zinc (4.52 mg /100 g), manganese (75.029 mg /100g) are more concentrated in maceration than a   decoction. For decoction of same plant, the situation is reversed with sodium (58.6mg /100g), calcium (12670 mg/100g), iron (18.51mg/100g) and potassium (2781 mg /100g). For pharmacological investigation, 32 rats Sprague Dawley male weighing 385-433g are isolated each in metabolic cages from 6 pm to 8am  and treated with 100mg/kg of Pericopsis laxiflora aqueous extracts. From 8am to 2pm the animals received only tap water in metabolic cages. The volumes of water intake and urine were not significantly different in the two groups (treated and untreated).The diuretic effect was not observed with 100mg/kg (b/w) . In addition   polyphenols, flavonoids, saponins and minerals such as potassium, magnesium and selenium are indicators of the vasodilatory and cardioprotective functions of Pericopis laxiflora aqueous extracts. The prescription of these extracts in traditional medicine must take into account the toxicity of the plant associated with a calcium and manganese content.

The Metabolic Syndrome increases the risk for atherosclerotic cardiovascular disease and type 2 Diabetes Mellitus. Increased fructose consumption and/or mineral deficiency have been associated with Metabolic Syndrome development. This study aimed to investigate the effects of 8 weeks consumption of a hypersaline sodium-rich naturally sparkling mineral water on 10% fructose-fed Sprague-Dawley rats (Metabolic Syndrome animal model). The ingestion of the mineral water (rich in sodium bicarbonate and with higher potassium, calcium, and magnesium content than the tap water used as control) reduced/prevented not only the fructose-induced increase of heart rate, plasma triacylglycerols, insulin and leptin levels, hepatic catalase activity, and organ weight to body weight ratios (for liver and both kidneys) but also the decrease of hepatic glutathione peroxidase activity and oxidized glutathione content. This mineral-rich water seems to have potential to prevent Metabolic Syndrome induction by fructose. We hypothesize that its regular intake in the context of modern diets, which have a general acidic character interfering with mineral homeostasis and are poor in micronutrients, namely potassium, calcium, and magnesium, could add surplus value and attenuate imbalances, thus contributing to metabolic and redox health and, consequently, decreasing the risk for atherosclerotic cardiovascular disease.

We investigated the effects of orange juice (OJ) or hesperidin, a component of OJ, on the pharmacokinetics of pravastatin (PRV) and the expression of both protein and mRNA of multidrug resistance-associated protein 2 (Mrp2) in the rat small intestine and liver. Eight-week-old male Sprague-Dawley rats were used in this study. OJ or a 0.079% hesperidin suspension was administered orally for 2 days. Tap water was given as a control. A single dose of PRV at 100 mg/kg p.o. was administered after 2 days of OJ, hesperidin, or tap water ingestion. The AUC, , andt1/2values of PRV were significantly increased in OJ group. Mrp2 protein and mRNA levels in the small intestine and liver, respectively, were significantly decreased after the ingestion of OJ. The same results were obtained with hesperidin. These results suggest that the changes in PRV pharmacokinetic parameters and the decrease in Mrp2 expression caused by OJ are due to hesperidin in the juice.

In Vivo Effects

AbstractThis study was designed to investigate the in vivo effects of ochratoxin A (OTA) and/or lycopene on the levels of selenium, zinc, and copper in the liver, kidneys, and testes of male Sprague-Dawley rats. The rats were treated with OTA (0.5 mg kg-1day-1) and/or lycopene (5 mg kg-1day-1) by gavage for 7 or 14 days. Trace element levels were measured by atomic absorption spectrometry. OTA significantly lowered selenium (20 % in the liver, 17 % in the kidney, and 40 % in the testis), zinc (24 % in the liver, 23 % in the kidney, and 26 % in the testis), and copper levels (40 % in the liver and 10 % in the kidney). Lycopene alone did not affect the trace element levels in any of the organs. In combination with OTA, however, it significantly restored liver, kidney, and testis selenium and zinc levels compared to the group treated with OTA alone. Our results have confirmed that depletion of trace elements in different organs is one of the mechanisms of action of OTA. They also suggest that lycopene interferes with this depleting effect and restores trace element levels, the implications of which need to be further investigated.

Chemopreventive Effect

AbstractChemopreventive effect of non-steroidal antiinflammatory drugs (NSAIDs) in mammary carcinogenesis was reported in several studies. In this study, the effect of a nonselective cyclooxygenase inhibitor diclofenac (DICLO) in the prevention of N-methyl-N-nitrosourea (NMU)-induced mammary carcinogenesis in Sprague-Dawley female rats was evaluated. NMU was administered to animals intraperitoneally in two doses of 50 mg kg−1 b.w. within postnatal days 42-48. In experiment A (short-term administration), DICLO was administrated intramuscularly (5 mg kg−1 b.w.) every other day, starting 3 days before and for subsequent 25 days after first NMU injection. In experiment B (long-term administration), DICLO was administered in tap water (0.01 mg ml−1) continually, starting 7 days before and for subsequent 22 weeks after first NMU dose. The study was terminated 22 weeks after the first dose of NMU in both experiments. After DICLO treatment, tumor frequency per group was reduced in both variants of drug administration: in experiment A by 38% and in experiment B by 39.5%. Moreover, DICLO decreased tumor incidence by 11.5% and delayed tumor latency by 14 days in experiment B. In our preventive-curative experiments DICLO decreased some parameters of NMU-induced rat mammary carcinogenesis, mainly the tumor frequency.

Sixty Sprague-Dawley rats were randomly assigned to eight groups of seven animals each. The remaining four animals served as a pooled control. The eight experimental groups received 68 r of x-irradiation during a 10-min. exposure period. The pooled control group received only sham-irradiation. Animals were presented a choice of tap water of 0.1% saccharin solution at delays following irradiation ranging from 0 to 96 hr. Subsequent saccharin consumption was recorded for 4 days following irradiation. Results showed a decrease in saccharin consumption in groups which had first received the saccharin from 0 to 12 hr. after irradiation. No significant decrease was exhibited by groups with delays of 24 hr. or more.

Site Of Action

Furosemide and hydrochlorothiazide (HCTZ) exert their diuretic actions by binding to apical Na+ transporters, viz., the Na+-K+-2Cl− cotransporter in the thick ascending limb and the Na+-Cl−cotransporter in the distal convoluted tubule, respectively. We carried out semiquantitative immunoblotting and immunohistochemistry of rat kidneys to investigate whether chronic administration of furosemide or HCTZ is associated with compensatory changes in the abundance of Na+ transporters downstream from the primary site of action. Osmotic minipumps were implanted into Sprague-Dawley rats to deliver furosemide (12 mg/day) or HCTZ (3.75 mg/day) for 7 days. To prevent volume depletion, all animals were offered tap water and a solution containing 0.8% NaCl and 0.1% KCl as drinking fluid. The diuretic/natriuretic response was quantified in response to both agents by using quantitative urine collections. Semiquantitative immunoblotting revealed that the abundances of thick ascending limb Na+-K+-2Cl− cotransporter and all three subunits of the epithelial Na+ channel (ENaC) were increased by furosemide infusion. HCTZ infusion increased the abundances of thiazide-sensitive Na+-Cl−cotransporter and β-ENaC in the cortex and β- and γ-ENaC in the outer medulla. Consistent with these results, β-ENaC immunohistochemistry showed a remarkable increase in immunoreactivity in the principal cells of collecting ducts with either diuretic treatment. These increases in the abundance of Na+transporters in response to chronic diuretic treatment may account for the generation of diuretic tolerance associated with long-term diuretic use.
