Methoxyflurane nephropathy. (1/625)

Investigations of methoxyflurane-induced nephrotoxicity in man have been extensively aided by the use of an animal model. To be of value the animal model must share similar metabolic pathways with man and have the same clinical manifestations of the diseases process. The Fischer 344 rat appears to meet these criteria. The predominant factors in the production of methoxyflurane nephrotoxicity appear to be high methoxyflurane dosage and serum inorganic fluoride concentration. It is likely that secondary factors include: (1) a high rate of methoxyflurane metabolism and sepsitivity of the kidney to inorganic fluoride toxicity: (2) concurrent treatment with other nephrotoxic drugs; (3) preexisting renal disease; (4) surgery of the urogenital tract, aorta, or renal vasculative; (5) repeat administration of methoxyflurane due to accumulation of inorganic fluoride and, perhaps, methoxyflurane induction of its own metabolism: and (6) concurrent treatment with enzyme-inducing drugs such as phenobarbital.  (+info)

Ca-releasing action of beta, gamma-methylene adenosine triphosphate on fragmented sarcoplasmic reticulum. (2/625)

beta,gamma-Methylene adenosine triphosphate (AMPOPCP) has two effects on fragmented sarcoplasmic reticulum (FSR), i.e., inhibition of the rate of Ca uptake and the induction of Ca release from FSR filled with Ca. The Ca release brought about by AMPOPCP has many features in common with the mechanism of Ca-induced Ca release: i) it is inhibited by 10 mM procaine; ii) the amount of Ca release increases with increase in the extent of saturation of FSR with Ca; iii) increase of the Ca concentration in the extent of saturation of FSR with Ca; iii) increase of the Ca concentration in the medium facilitates the release of Ca. However, no facilitation of Ca release upon decrease of Mg concentration in the medium is observable. AMPOPCP and caffeine potentiate each other remarkably in their Ca-releasing action, irrespective of the kind of substrate. From the mode of action of AMPOPCP on the rate of Ca uptake, the amount of phosphorylated intermediate (EP), and the effect on Sr release, it is suggested that the state of the FSR-ATP complex is crucial for Ca-induced Ca release.  (+info)

Bound forms of Ca taken up by the synaptic plasma membrane. (3/625)

Temperature dependent Ca-binding by the synaptic plasma membrane was increased in the presence of ATP and Mg++. Apparent Km for ATP was about 2.8 X 10(-5) M and optimal concentration of Mg++ was 2 mM in the presence of 2 mM ATP. After preincubation with nonradioactive Ca++, ATP and Mg++ to attain a steady state, addition of 45Ca resulted in remarkable labelling of the membrane, indicating rapid turnover of most of the membrane bound Ca. The presence of oxalate (60 mM) greatly increased Ca up-take on prolonged incubation. The Ca uptake in presence and absence of oxalate had similar substrate specificity and was similarly influenced by various monovalent cations. Furthermore, activities for Ca-uptake in the presence and absence of oxalate could not be separated by sucrose density gradient centrifugation of the synaptic plasma membrane fraction. Accordingly, it was considered that Ca++ in the medium was taken up by surface of the membrane, ATP- and temperature-dependently and then transferred into a cavity where the Ca-oxalate complex is formed.  (+info)

Cyclosporin A treatment alters characteristics of Ca2+-release channel in cardiac sarcoplasmic reticulum. (4/625)

Chronic treatment with cyclosporin A (CsA) has been reported (H. S. Banijamali, M. H. ter Keurs, L. C. Paul, and H. E. ter Keurs. Cardiovasc. Res. 27: 1845-1854, 1993; I. Kingma, E. Harmsen, H. E. ter Keurs, H. Benediktsson, and L. C. Paul. Int. J. Cardiol. 31: 15-22, 1991) to induce reversible alterations of contractile properties in rat hearts. To define the molecular mechanisms underlying the physiological alterations, the Ca2+-release channel (CRC) and Ca2+-ATPase from sarcoplasmic reticulum in rats were examined. Ryanodine binding to whole homogenates of rat hearts shows time- and dose-dependent alterations in CRC properties by CsA. On 3 wk of treatment with 15 mg CsA. kg body wt-1. day-1, 1) maximal ryanodine binding (Bmax) decreased, 2) the dissociation constant of ryanodine (Kd) increased, 3) caffeine sensitivity of CRC increased, and 4) ruthenium red sensitivity of CRC decreased. On the other hand, Bmax and Kd of ryanodine binding in rat skeletal muscles were not changed. Ryanodine-sensitive oxalate-supported Ca2+ uptake in whole homogenates was lower in CsA-treated rat hearts than in control hearts, whereas total Ca2+ uptake in the presence of 500 M ryanodine was not changed. Functional experiments with rapamycin and Western blot analysis suggest that the CsA-induced alteration of ryanodine binding is due at least in part to an upregulation of calcineurin. The heart muscle-specific alterations of CRC could be responsible for the previously reported contractile changes of CsA-treated rat hearts.  (+info)

Fomepizole for the treatment of ethylene glycol poisoning. Methylpyrazole for Toxic Alcohols Study Group. (5/625)

BACKGROUND: Ethylene glycol poisoning causes metabolic acidosis and renal failure and may cause death. The standard treatment is inhibition of alcohol dehydrogenase with ethanol, given in intoxicating doses, and adjunctive hemodialysis. We studied the efficacy of fomepizole, a new inhibitor of alcohol dehydrogenase, in the treatment of ethylene glycol poisoning. METHODS: We administered intravenous fomepizole to 19 patients with ethylene glycol poisoning (plasma ethylene glycol concentration, > or =20 mg per deciliter [3.2 mmol per liter]). Patients who met specific criteria also underwent hemodialysis. Treatment was continued until plasma ethylene glycol concentrations were less than 20 mg per deciliter. Acid-base status, renal function, the kinetics of fomepizole, and ethylene glycol metabolism were assessed at predetermined intervals. RESULTS: Fifteen of the patients initially had acidosis (mean serum bicarbonate concentration, 12.9 mmol per liter). Acid-base status tended to normalize within hours after the initiation of treatment with fomepizole. One patient with extreme acidosis died. In nine patients, renal function decreased during therapy; at enrollment, all nine had high serum creatinine concentrations and markedly elevated plasma glycolate concentrations (> or =97.7 mg per deciliter [12.9 mmol per liter]). None of the 10 patients with normal serum creatinine concentrations at enrollment had renal injury during treatment; all 10 had plasma glycolate concentrations at or below 76.8 mg per deciliter (10.1 mmol per liter). Renal injury was independent of the initial plasma ethylene glycol concentration. The plasma concentration of glycolate and the urinary excretion of oxalate, the major metabolites of ethylene glycol, uniformly fell after the initiation of fomepizole therapy. Few adverse effects were attributable to fomepizole. CONCLUSIONS: In patients with ethylene glycol poisoning, fomepizole administered early in the course of intoxication prevents renal injury by inhibiting the formation of toxic metabolites.  (+info)

Urinary outputs of oxalate, calcium, and magnesium in children with intestinal disorders. Potential cause of renal calculi. (6/625)

24-hour urinary outputs of oxalate, calcium, and magnesium have been determined in a total of 62 children aged 3 months to 17 years who fell into the following groups: (i) 16 normal controls, (ii) 3 with primary hyperoxaluria, (iii) 9 with small and/or large intestinal resections, (iv) 9 with untreated coeliac disease, (v) 5 with pancreatic dysfunction, and (vi) a miscellaneous group of 20 children with a variety of intestinal disorders. Taken as a whole, 58% of patients with intestinal disorders had hyperoxaluria, and of these 7% had urinary outputs of oxalate which fell within the range seen in primary hyperoxaluria. The proportion of children with hyperoxaluria in the different diagnostic groups was as follows: intestinal resections (78%), coeliac disease (67%), pancreatic dysfunction (80%), and miscellaneous (45%). 35% of the patients with hyperoxaluria had hypercalciuria, whereas magnesium excretion was normal in all subjects studied. In 2 patients treatment of the underlying condition was accompanied by a return of oxalate excretion to normal. These results indicate that hyperoxaluria and hypercalciuria are common in children with a variety of intestinal disorders, and that such children may be at risk of developing renal calculi without early diagnosis and treatment.  (+info)

Intake of vitamins B6 and C and the risk of kidney stones in women. (7/625)

Urinary oxalate is an important determinant of calcium oxalate kidney stone formation. High doses of vitamin B6 may decrease oxalate production, whereas vitamin C can be metabolized to oxalate. This study was conducted to examine the association between the intakes of vitamins B6 and C and risk of kidney stone formation in women. The relation between the intake of vitamins B6 and C and the risk of symptomatic kidney stones were prospectively studied in a cohort of 85,557 women with no history of kidney stones. Semiquantitative food-frequency questionnaires were used to assess vitamin consumption from both foods and supplements. A total of 1078 incident cases of kidney stones was documented during the 14-yr follow-up period. A high intake of vitamin B6 was inversely associated with risk of stone formation. After adjusting for other dietary factors, the relative risk of incident stone formation for women in the highest category of B6 intake (> or =40 mg/d) compared with the lowest category (<3 mg/d) was 0.66 (95% confidence interval, 0.44 to 0.98). In contrast, vitamin C intake was not associated with risk. The multivariate relative risk for women in the highest category of vitamin C intake (> or =1500 mg/d) compared with the lowest category (<250 mg/d) was 1.06 (95% confidence interval, 0.69 to 1.64). Large doses of vitamin B6 may reduce the risk of kidney stone formation in women. Routine restriction of vitamin C to prevent stone formation appears unwarranted.  (+info)

Regulation of Ca2+ transport by sarcoplasmic reticulum Ca2+-ATPase at limiting [Ca2+]. (8/625)

The factors regulating Ca2+ transport by isolated sarcoplasmic reticulum (SR) vesicles have been studied using the fluorescent indicator Fluo-3 to monitor extravesicular free [Ca2+]. ATP, in the presence of 5 mM oxalate, which clamps intravesicular [Ca2+] at approximately 10 microM, induced a rapid decline in Fluo-3 fluorescence to reach a limiting steady state level. This corresponds to a residual medium [Ca2+] of 100 to 200 nM, and has been defined as [Ca2+]lim, whilst thermodynamic considerations predict a level of less than 1 nM. This value is similar to that measured in intact muscle with Ca2+ fluophores, where it is presumed that sarcoplasmic free [Ca2+] is a balance between pump and leaks. Fluorescence of Fluo-3 at [Ca2+]lim was decreased 70% to 80% by histidine, imidazole and cysteine. The K0.5 value for histidine was 3 mM, suggesting that residual [Ca2+]lim fluorescence is due to Zn2+. The level of Zn2+ in preparations of SR vesicles, measured by atomic absorption, was 0.47+/-0.04 nmol/mg, corresponding to 0.1 mol per mol Ca-ATPase. This is in agreement with findings of Papp et al. (Arch. Biochem. Biophys., 243 (1985) 254-263). Histidine, 20 mM, included in the buffer, gave a corrected value for [Ca2+]lim of 49+/-1.8 nM, which is still higher than predicted on thermodynamic grounds. A possible 'pump/leak' mechanism was tested by the effects of varying active Ca2+ transport 1 to 2 orders with temperature and pH. [Ca2+]lim remained relatively constant under these conditions. Alternate substrates acetyl phosphate and p-NPP gave similar [Ca2+]lim levels even though the latter substrate supported transport 500-fold slower than with ATP. In fact, [Ca2+]lim was lower with 10 mM p-NPP than with 5 mM ATP. The magnitude of passive efflux from Ca-oxalate loaded SR during the steady state of [Ca2+]lim was estimated by the unidirectional flux of 45Ca2+, and directly, following depletion of ATP, by measuring release of 40Ca2+, and was 0.02% of Vmax. Constant infusion of CaCl2 at [Ca2+]lim resulted in a new steady state, in which active transport into SR vesicles balances the infusion rate. Varying infusion rates allows determination of [Ca2+]-dependence of transport in the absence of chelating agents. Parameters of non-linear regression were Vmax=853 nmol/min per mg, K0.5(Ca)=279 nM, and nH(Ca)=1.89. Since conditions employed in this study are similar to those in the sarcoplasm of relaxed muscle, it is suggested that histidine, added to media in studies of intracellular Ca2+ transients, and in the relaxed state, will minimise contribution of Zn2+ to fluophore fluorescence, since it occurs at levels predicted in this study to cause significant overestimation of cytoplasmic free [Ca2+] in the relaxed state. Similar precautions may apply to non-muscle cells as well. This study also suggests that [Ca2+]lim in the resting state is a characteristic feature of Ca2+ pump function, rather than a balance between active transport and passive leakage pathways.  (+info)

Calcium oxalate (CaOx) is the major constituent of about 75% of all urinary stone and the secondary hyperoxaluria is a primary risk factor. Current treatment options for the patients with hyperoxaluria and CaOx stone diseases are limited. Oxalate degrading bacteria might have beneficial effects on urinary oxalate excretion resulting from decreased intestinal oxalate concentration and absorption. Thus, the aim of the present study is to examine the in vivo oxalate degrading ability of genetically engineered Lactobacillus plantarum (L. plantarum) that constitutively expressing and secreting heterologous oxalate decarboxylase (OxdC) for prevention of CaOx stone formation in rats. The recombinants strain of L. plantarum that constitutively secreting (WCFS1OxdC) and non-secreting (NC8OxdC) OxdC has been developed by using expression vector pSIP401. The in vivo oxalate degradation ability for this recombinants strain was carried out in a male wistar albino rats. The group I control; groups II, III, IV and V
View Poster. INTRODUCTION. The impact of dietary protein intake on urinary oxalate has not been clearly delineated. Potential reasons include inaccurate dietary assessment of oxalate, calcium, and vitamin C, as well as lack of control for the amount and source of protein. This study will be the first to use the NDSR to obtain a precise dietary assessment of these factors on self-selected rather than controlled diets. The objective of this study is to evaluate the impact of the amount and source of protein intake on urinary oxalate for patients with recent urolithiasis using the NDSR.. METHODS. We prospectively recruited patients from a single institution who either passed or underwent treatment for a calcium oxalate stone within 6 months and were subsequently referred for a complete metabolic work-up. Patients with metabolic predispositions to stone formation or taking medications that may impact urine parameters were excluded. Total dietary intake was obtained using a 3 day food record and 24 ...

people eating a synthetic oxalate free high calcium diet (graph at left). As diet oxalate increased, urine oxalate rose from 0 to 10 mg/2500 kcal/d, urine oxalate rose steeply from 10 to 14 mg/gm urine creatinine. It rose more slowly, from 14 to barely 15 mg/gm urine creatinine as diet oxalate was increased to 50 mg/2500 kcal/d, and more or less at the same slope thereafter so that an increase from 50 mg/2500 kcal/d up to 250 mg/2500 kcal/d increased urine oxalate only from 14 to 18. The closed symbols are whole food the open symbols synthetic diets.. From this work the percent oxalate absorption could be calculated as around 10 - 15% and the contribution of diet oxalate to urine oxalate excretion as around 25 - 40% when intake of oxalate was between 50 and 350 mg/2500 kcal. Therefore one can consider a whole food 1000 mg calcium 50 mg oxalate as a usable low oxalate diet, and a 150 - 250 mg oxalate diet as relatively high.. The balance between diet calcium and diet oxalate does not matter ...
1. We have measured the plasma oxalate concentration (P Ox ), urinary oxalate excretion (U Ox ), oxalate equilibrium distribution volume (ODV), oxalate metabolic pool size [(ODV) × (P Ox )], total plasma oxalate clearance (PC Ox ), renal (or dialyser) oxalate clearance (RC Ox ), non-renal oxalate clearance (NRC Ox ) and the tissue oxalate accretion rate (TOA)= [(NRC Ox ) × (P Ox )] in three patients with severe renal failure due to primary hyperoxaluria who were being treated by peritoneal dialysis or haemodialysis, or by renal transplantation. The clearance (either GFR or dialyser) of [ 99m Tc]diethylenetriaminepenta-acetate (DTPA) and the extracellular fluid volume (ECF) measured as [ 99m Tc]DTPA distribution volume were also determined. 2. Negligible amounts of 14 C were found in faeces or as 14 CO 2 in expired air and hence (NRC Ox ) = (PC Ox -RC Ox ). 3. Haemodialysis removed oxalate more efficiently than peritoneal dialysis in the patient where a direct comparison was possible. Neither ...
Total, soluble and insoluble oxalates were extracted and analyzed by high performance liquid chromatography (HPLC) following the preparation of kimchi using silver beet (Beta vulgaris var. cicla) stems and leaves. As silver beet contains high oxalate concentrations and consumption of high levels can cause the development of kidney stones in some people, the reduction of oxalate during preparation and fermentation of kimchi was investigated. The silver beet stems and leaves were soaked in a 10% brine solution for 11 h and then washed in cold tap water. The total, soluble and insoluble oxalate contents of the silver beet leaves were reduced by soaking in brine, from 4275.81 ± 165.48 mg/100 g to 3709.49 ± 216.51 mg/100 g fresh weight (FW). Fermenting the kimchi for 5 days at 19.3 ± 0.8 °C in 5 L ceramic jars with a water airtight seal resulted in a mean 38.50% reduction in total oxalate content and a mean 22.86% reduction in soluble oxalates. The total calcium content was essentially the same before
Increased urinary oxalate excretion (hyperoxaluria) promotes the formation of calcium oxalate crystals. Monogenic diseases due to hepatic enzyme deficiency result in chronic hyperoxaluria, promoting end-stage renal disease in children and young adults. Ethylene glycol poisoning also results in hyperoxaluria, promoting acute renal failure and frequently death. Stiripentol is an antiepileptic drug used to treat children affected by Dravet syndrome. It has been shown to inhibit neuronal lactate dehydrogenase 5 enzyme. As this isoenzyme is also the last step of hepatic oxalate production, we hypothesized that stiripentol would potentially reduce hepatic oxalate production and urine oxalate excretion. In vitro, stiripentol decreased the synthesis of oxalate by hepatocytes in a dose-dependent manner. In vivo, oral administration of stiripentol significantly reduced urine oxalate excretion in rats. Stiripentol protected the kidneys against calcium oxalate crystal deposits in acute ethylene glycol ...

1. Both the peroxisomal, flavin-linked glycollate oxidase [(S)-2-hydroxy-acid oxidase; EC 1.1.3.15] and the cytosolic, nicotinamide-adenine dinucleotide (NAD)-linked lactate dehydrogenase (l-lactate dehydrogenase; EC 1.1.1.27) are thought to contribute to the formation of oxalate from its immediate precursors, glycollate and glyoxylate, but the relative contributions of each enzyme to endogenous oxalate production is not known.. 2. In rat liver homogenates, [14C]oxalate production from labelled glycollate is halved and that from labelled glyoxylate is increased fourfold by the addition of either NAD or NADH.. 3. In isolated rat hepatocytes, the 3-hydroxy-1H-pyrrole-2,5-dione derivatives of glycollate, which are specific inhibitors of glycollate oxidase, have a greater effect on glycollate metabolism than on glyoxylate metabolism.. 4. These findings are consistent with an important role for lactate dehydrogenase in oxalate formation from glyoxylate.. 5. With human and rat liver homogenates and ...

Oxalate is produced by several catabolic pathways in plants. The best characterized pathway for subsequent oxalate degradation is via oxalate oxidase, but some species, such as Arabidopsis thaliana, have no oxalate oxidase activity. Previously, an alternative pathway was proposed in which oxalyl-CoA synthetase (EC 6.2.1.8) catalyzes the first step, but no gene encoding this function has been found. Here, we identify ACYL-ACTIVATING ENZYME3 (AAE3; At3g48990) from Arabidopsis as a gene encoding oxalyl-CoA synthetase. Recombinant AAE3 protein has high activity against oxalate, with Km = 149.0 ± 12.7 μM and Vmax = 11.4 ± 1.0 μmol/min/mg protein, but no detectable activity against other organic acids tested. Allelic aae3 mutants lacked oxalyl-CoA synthetase activity and were unable to degrade oxalate into CO2. Seeds of mutants accumulated oxalate to levels threefold higher than the wild type, resulting in the formation of oxalate crystals. Crystal formation was associated with seed coat defects ...
As mentioned above, oxalates are very common in plant foods. They may also be found in smaller amounts in eggs, meat and dairy. Simply put, oxalates are a component of all food. In practice, this means it is impossible to completely avoid oxalates, and still consume a nutritious diet. However, as the low oxalate diet aims to demonstrate, it is certainly possible to keep the amount of oxalates consumed in the food to a minimum, and still eat healthfully.. In addition, the body is capable of converting other substances into oxalates. For example, if a person consumes more Vitamin C than their body needs, the excess ascorbic acid is often converted to oxalic acid. This is one of the hidden hazards of the common practice of taking megadoses of Vitamin C (reference here).. What may be more important are the ways that oxalates are stored in the body. For example, while we know that kidney stones are often formed from calcium oxalate, we do not yet know how much of this type of kidney stone formation ...
Wood biodegradation is primarily caused by Basidiomycetous white or brown rot fungi. White rot fungi are unique in degrading lignin, while brown rot fungi circumvent lignin to degrade holocellulose via iron-dependent oxidative chemistry. Both groups of fungi produce oxalate during wood metabolism, and oxalic acid secretion may promote wood decay by reducing pH, mobilizing iron, detoxifying copper, and immobilizing calcium. The function of oxalate during wood decay remains unclear, however, primarily due to difficulties in extracting bound oxalate and to inconsistencies among analytical techniques. This work aims to improve oxalate quantification during wood biodegradation and to better characterize fungal oxalate production in relation to cation availability. Accurate and repeatable soluble and acid-extractable oxalate quantification was achieved with an improved high-performance liquid chromatography (HPLC) method. This procedure was verified in fungal liquid cultures by demonstrating a
Before we get into down side of elevated oxalates it is important to repeat something I said my previous post titled Oxalates and MTHFR: Understanding the Gut-Kidney Axis - that oxalates in mild amounts are not a problem for the body. As long as the body can safely detoxify each molecule of oxalate, they will not bother us. Even though they are nasty in high amounts, the body has the ability to get rid of oxalates. We have already seen how proper digestion and gallbladder function protects us from absorbing oxalates. What we havent talked about yet is how our body gets rid of oxalates once they enter and build up to toxic levels. Unfortunately life is all about tradeoffs and that principal holds true when it comes to how the body detoxifies oxalates.. Any discussion of oxalates is incomplete without mentioning sulfate. Sulfate is one of the most amazing molecules in our bodies. Sulfate is an essential byproduct of our methylation cycle and without it we cannot survive. Sulfate helps us seal our ...
Magnesium oxalate is an inorganic compound comprising a magnesium cation with a 2+ charge bonded to an oxalate anion. It has the chemical formula MgC2O4. Magnesium oxalate is a white solid that comes in two forms: an anhydrous form and a dihydrate form where two water molecules are complexed with the structure. Both forms are practically insoluble in water and are insoluble in organic solutions. Some oxalates can be found in nature and the most known naturally occurring oxalates are whewellite and weddellite, which are calcium oxalates. Magnesium oxalate has been found naturally near Mill of Johnston which is located close to Insch in northeast Scotland. The naturally occurring magnesium oxalate is called glushinskite. The magnesium oxalate was found at the lichen and rock interface on serpentinite. It was found in a creamy white layer which was mixed in with the lichen fungus. A scanning electron micrograph of samples taken showed that the crystals had a pyramidal structure with both curved and ...
Bariatric surgery is associated with hyperoxaluria hence predisposing to nephrolithiasis. The present study aimed to investigate the underlying mechanisms contributing to increased urinary oxalate in a mini-gastric bypass (MGB) surgery model in rats under different dietary conditions. The expression of intestinal oxalate transporters was also evaluated. Male rats underwent MGB (n = 21) or Sham procedure (n = 21) and after recovery were fed a standard or high-fat diet with or without oxalate for 8 weeks. Stool and urine were collected before surgery (baseline) and at the end of protocol (final), when intestinal fragments were harvested for expression of Slc26a3 and Slc26a6 oxalate transporters. MGB groups fed with fat, irrespective of oxalate supplementation, presented steatorrhea. In MGB animals fed with fat and oxalate (Fat + Ox), final values of urinary oxalate and calcium oxalate supersaturation risk were markedly and significantly increased versus baseline or Sham animals under the same ...

The low oxalate diet consists of consuming a diet low in oxalates. It is a newer diet for autism that came about from the work of Susan Owens and the observation from parents that foods high in oxalates were problematic for their children.. While this is a newer diet, there is a lot of science that helps explain what might be going on for some children with autism. Oxalates are sharp crystals and are the same ones responsible for certain forms of kidney stones. Oxalate crystals can be inflammatory and damaging to a childs delicate biochemistry and the low oxalate diet reduces these compounds. In cells, oxalates can lead to oxidative damage, depletion of glutathione, pain associated with urination, and inflammation related to the immune system. Glutathione is important for immune function, inflammatory regulation, detoxification, and antioxidant status. Levels of glutathione are often low in children with autism; therefore oxalates could exacerbate challenges for some of these ...
On this diet, we elminate foods that are high in oxalates, mostly certain fruits and vegetables, a lot of grains, nuts, and seeds. Beef, chicken, pork, eggs, and fish contain no oxalates and can be eaten freely. The goal is stay low oxalate, but even doing low and medium oxalate will help symptoms, and that is what we are doing right now until we can get a handle on the diet and learn how many oxalates Lynsey can handle a day. What is an oxalate?. (Since we are very new to this diet, and I am still learning, I will paste the answers to these questions from another web site and include the link if you want to explore that web site more.). Here is a link to Great Plains Laboratory and their explanation of oxalates, and particularly how it relates to autism. It is very informative. http://www.greatplainslaboratory.com/home/eng/oxalates.asp.

This latter is dependent on diet calcium. In the graph to the left, diet calcium is on the x axis and urine oxalate on the y axis. Each point represents values from trial data in which diet calcium was altered and urine oxalate measured. Oxalate intake varied from 200 to 50 mg/d and the symbol size reflects it. The data for the trials are available from the main article I wrote about this topic. The names are those of the principal investigators.. As diet calcium increases, urine oxalate falls more or less independent of oxalate intake. At 1,200 mg, most points are between 25 and 35 mg/d.. This does not mean that we no longer need to be concerned with diet oxalate. But it does mean that the recommended US diet calcium intake of 1,200 mg/d lessens the needed stringency.. In the small inset box, Hess makes this point with considerable drama. He gave people 2,000 mg/d of oxalate, a shocking amount, with 1,200 mg/d of diet calcium. Despite the drastic diet oxalate excess, urine oxalate was only 80 ...

TY - JOUR. T1 - Ascorbate degradation in tomato leads to accumulation of oxalate, threonate and oxalyl threonate. T2 - Ascorbate degradation in tomato. AU - Truffault, Vincent. AU - Fry, Stephen. AU - Stevens, Rebecca G. AU - Gautier, Helene. PY - 2016/11/26. Y1 - 2016/11/26. N2 - Ascorbate content in plants is controlled by its synthesis from carbohydrates, recycling of the oxidized forms and degradation. Of these pathways, ascorbate degradation is the least studied and represents a lack of knowledge which could impair improvement of ascorbate content in fruits and vegetables as degradation is non-reversible and leads to a depletion of the ascorbate pool. The present study revealed the nature of degradation products using [14C]ascorbate labelling in tomato, a model plant for fleshy fruits; oxalate and threonate are accumulated in leaves, as is oxalyl threonate. Carboxypentonates coming from diketogulonate degradation were detected in relatively insoluble (cell wall-rich) leaf material. No ...

View Poster. INTRODUCTION. The impact of dietary protein intake on urinary oxalate has not been clearly delineated. Potential reasons include inaccurate dietary assessment of oxalate, calcium, and vitamin C, as well as lack of control for the amount and source of protein. This study will be the first to use the NDSR to obtain a precise dietary assessment of these factors on self-selected rather than controlled diets. The objective of this study is to evaluate the impact of the amount and source of protein intake on urinary oxalate for patients with recent urolithiasis using the NDSR.. METHODS. We prospectively recruited patients from a single institution who either passed or underwent treatment for a calcium oxalate stone within 6 months and were subsequently referred for a complete metabolic work-up. Patients with metabolic predispositions to stone formation or taking medications that may impact urine parameters were excluded. Total dietary intake was obtained using a 3 day food record and 24 ...

Figure 4.1 - Pathways and mechanisms of how oxalates are absorbed and produced inside the human body.. Bile acts like soap and soap chops fat globules into tiny balls called micelles - a chemical property we need in order to absorb all those healthy Omega 3 fats and fat-soluble vitamins like A, D, E, and K. When the gallbladder is working properly the fat in our diet is absorbed in the small intestine and the oxalates in our meal form a compound with calcium called calcium-oxalate which we cannot absorb.5 In this way bile helps us absorb the fats we need and pass the oxalates in the stool so they dont cause problems (Figure 4.1). Normally our body will not absorb all calcium from out diet. The undigested calcium is needed to bind with the oxalates in the gut which helps us to rid our body of this toxic molecule. However the same cannot be said when the gallbladder system begins to malfunction.. When we stop releasing bile, whether it is from stomach dysfunction, taurine deficiency, or some ...
The menu options on a low oxalate diet are numerous and varied. The diet provides a good nutritional base as long as your eat an array of the available foods.. Implementing the diet requires study, counting numbers, and ongoing dedication. A low oxalate diet generally means keeping your intake of oxalate from food and beverages between 40 and 60 mg. per day, depending upon your weight. Some people find they need a very low oxalate intake, while others can tolerate more. Each person needs to experiment and find their own level. To use the diet correctly, you will have to count your daily intake and be cognizant of portion sizes.. It is also helpful to bear in mind that oxalate levels can vary dramatically due to growing conditions as well as cooking methods. The lists provided are guides, not the ultimate truth. While some foods routinely test low for oxalate and people rarely report problems with them, others do not. Zucchini and green beans are examples of foods that test at different levels. ...
I personally had severe dietary oxalate issues in 2012 which manifested as excruciating foot pain. It was a combination of hot-burning-coals-pain and shards-of-glass-pain. It was just after my book, The Antianxiety Solution (my Amazon link), came out. Due to my book tours and events, I would be on my feet all day presenting, often for 3 full consecutive days, so I figured that must be the reason. When I travelled, I took a blender and made smoothies with berries, ate plenty of healthy nuts as my snacks and took kale chips with me to make sure I was getting my greens. Kiwi fruit was a favorite of mine!. I was eating a high oxalate diet and had no idea until I heard Julie present at an Integrative Medicine for Mental Health Conference on dietary oxalates and autism. A light-bulb went off and then I worked with her to learn about oxalates and figure out if it was in fact because of oxalates and sure enough, as soon as I removed high and medium oxalate foods the pain resolved. Note: the advice is ...

Calcium stones. Most kidney stones are calcium stones, usually in the form of calcium oxalate. Oxalate is a naturally occurring substance found in food and is also made daily by your liver. Some fruits and vegetables, as well as nuts and chocolate, have high oxalate content.. Dietary factors, high doses of vitamin D, intestinal bypass surgery and several metabolic disorders can increase the concentration of calcium or oxalate in urine.. Calcium stones may also occur in the form of calcium phosphate. This type of stone is more common in metabolic conditions, such as renal tubular acidosis. It may also be associated with certain migraine headaches or with taking certain seizure medications, such as topiramate (Topamax).. ...

Oxalate, a non-essential end product of metabolism, causes hyperoxaluria and eventually calcium oxalate (CaOx) stone disease. Kidney cells exposed to oxalate stress results in generation of reactive oxygen species (ROS) and progression of stone formation. Perturbations in endoplasmic reticulum (ER) result in accumulation of misfolded proteins and Ca2+ ions homeostasis imbalance and serve as a common pathway for various diseases, including kidney disorders. ER stress induces up-regulation of pro-survival protein glucose-regulated protein 78 (GRP78) and pro-apoptotic signaling protein C/EBP homologous protein (CHOP). Since the association of oxalate toxicity and ER stress on renal cell damage is uncertain, the present study is an attempt to elucidate the interaction of GRP78 with oxalate by computational analysis and study the role of ER stress in oxalate-mediated apoptosis in vitro and in vivo. Molecular docking results showed that GRP78-oxalate/CaOx interaction takes place. Oxalate stress ...
BACKGROUND: Oxalate exposure produces oxidant stress in renal epithelial cells leading to death of some cells and adaptation of others. The pathways involved in these diverse actions remain unclear, but appear to involve activation of phospholipase A2 (PLA2) and redistribution of membrane phospholipids. The present studies examined the possibility that oxalate actions may also involve increased accumulation of ceramide, a lipid-signaling molecule implicated in a variety of pathways, including those leading to apoptotic cell death. METHODS: Ceramide accumulation was examined in renal epithelial cells from pig kidney (LLC-PK1 cells) and from dog kidney [Madin-Darby canine kidney (MDCK cells)] using the diacylglycerol kinase assay. Sphingomyelin degradation was assessed by monitoring the disappearance of 3H-sphingomyelin from cells that had been prelabeled with [3H]-choline. The effects of oxalate were compared with those of other oxidants (peroxide, xanthine/xanthine oxidase), other organic acids (formate
