Metabolic acidosis-induced retinopathy in the neonatal rat. (1/1411)

PURPOSE: Carbon dioxide (CO2)-induced retinopathy (CDIR) in the neonatal rat, analogous to human retinopathy of prematurity (ROP), was previously described by our group. In this model, it is possible that CO2-associated acidosis provides a biochemical mechanism for CDIR. Therefore, the effect of pure metabolic acidosis on the developing retinal vasculature of the neonatal rat was investigated. METHODS: A preliminary study of arterial blood pH was performed to confirm acidosis in our model. In neonatal rats with preplaced left carotid artery catheters, acute blood gas samples were taken 1 to 24 hours after gavage with either NH4Cl 1 millimole/100 g body weight or saline. In the subsequent formal retinopathy study, 150 newborn Sprague-Dawley rats were raised in litters of 25 and randomly assigned to be gavaged twice daily with either NH4Cl 1 millimole/100 g body weight (n = 75) or saline (n = 75) from day 2 to day 7. After 5 days of recovery, rats were killed, and retinal vasculature was assessed using fluorescein perfusion and ADPase staining techniques. RESULTS: In the preliminary pH study, the minimum pH after NH4Cl gavage was 7.10+/-0.10 at 3 hours (versus 7.37+/-0.03 in controls, mean +/- SD, P < 0.01). In the formal retinopathy study, preretinal neovascularization occurred in 36% of acidotic rats versus 5% of controls (P < 0.001). Acidotic rats showed growth retardation (final weight 16.5+/-3.0 g versus 20.2+/-2.6 g, P < 0.001). The ratio of vascularized to total retinal area was smaller in acidotic rats (94%+/-4% versus 96%+/-2%, P < 0.001). CONCLUSIONS: Metabolic acidosis alone induces neovascularization similar to ROP in the neonatal rat. This suggests a possible biochemical mechanism by which high levels of CO2 induce neovascularization and supports the suggestion that acidosis may be an independent risk factor for ROP.  (+info)

Arteriovenous differences for amino acids and lactate across kidneys of normal and acidotic rats. (2/1411)

1. Arteriovenous differences fro amino acids across kidneys of normal and chronically acidotic rats were measured. Glutamine was the only amino acid extracted in increased amounts in acidosis. There was a considerable production of serine by kidneys from both normal and acidotic rats. 2. The arterial blood concentration of glutamine was significantly decreased in acidotic animals. 3. The glutamine extracted by kidneys of acidotic rats was largely and probably exclusively derived from the plasma. 4. The blood lactate concentration was unchanged in acidosis, as was the uptake of lactate by the kidney.  (+info)

Abnormal ductus venosus blood flow: a clue to umbilical cord complication. (3/1411)

We report a case of umbilical cord complication causing, fetal hypoxemia and acidemia. At 30 weeks of gestation, the patient was referred because of slightly increased amniotic fluid volume and a non-reactive cardiotocogram. Biometry was appropriate for gestational age. Umbilical artery and fetal aortic Doppler findings were normal, whereas diastolic blood flow velocities in the middle cerebral artery were increased and the ductus venosus showed severely abnormal flow velocity waveforms with reversal of flow during atrial contraction. Since other reasons for fetal hypoxemia could be excluded, careful examination of the umbilical cord was performed. Traction of the hypercoiled umbilical cord due to its course around the fetal neck and shoulders was suspected. Cesarean section confirmed the sonographic findings and fetal blood gases revealed fetal acidemia. This case indicates that investigation of fetal venous blood flow may also help to identify fetal jeopardy due to reasons other than increased placental vascular resistance.  (+info)

Epidural analgesia with bupivacaine does not improve splanchnic tissue perfusion after aortic reconstruction surgery. (4/1411)

Inadequate splanchnic tissue perfusion is relatively common during and after aortic surgery. We hypothesized that vasodilation caused by thoracic epidural analgesia improves splanchnic blood flow and tissue perfusion after aortic surgery. In this prospective, randomized, controlled study, we studied 20 patients undergoing elective aortic-femoral or aortic-iliac reconstruction surgery. Gastric and sigmoid colon mucosal PCO2 and pH were measured during surgery. An epidural bolus of bupivacaine 40 mg followed by infusion of 15 mg h-1 was started after operation in 10 patients. After operation, splanchnic blood flow and gastric and sigmoid colon mucosal PCO2 and pH were measured before and 2 h after the start of epidural analgesia. During surgery, the gastric mucosal-arterial PCO2 difference remained stable, whereas the sigmoid mucosal-arterial PCO2 difference increased during aortic clamping but returned to pre-clamping values after declamping. After operation, epidural analgesia had no effect on gastric or sigmoid mucosal-arterial PCO2 differences or on splanchnic blood flow.  (+info)

Temporal differences in actions of calcium channel blockers on K+ accumulation, cardiac function, and high-energy phosphate levels in ischemic guinea pig hearts. (5/1411)

We investigated temporal differences in the protective action of three types of Ca2+ channel blockers in myocardial ischemia, focusing particularly on the blocking ability under depolarizing conditions. The effects of diltiazem, verapamil, and nifedipine on extracellular potassium concentration ([K+]e), acidosis, and level of metabolic markers were examined during 30-min global ischemia and postischemic left ventricular (LV) function in isolated guinea pig hearts. Diltiazem and verapamil, but not nifedipine, inhibited the late phase (15-30 min) of [K+]e elevation, whereas all three blockers delayed the onset of the early phase (0-8 min) of [K+]e elevation. Diltiazem and verapamil inhibited ischemic contracture and improved postischemic LV function to a greater extent. These differences appeared to be linked to preservation of ATP and creatine phosphate and delay of cessation of anaerobic glycolytic activity. Maneuvers to preserve energy sources during ischemia (decrease in external Ca2+ concentration or pacing at a lower frequency) attenuated the late phase of [K+]e elevation. Inhibition of LV pressure was potentiated 12- and 8.2-fold by diltiazem and verapamil, respectively, at 8.9 mM K+ as compared with 2.9 mM K+, whereas that by nifedipine was unchanged. These results indicate that the differential cardioprotection of Ca2+ channel blockers in the late period of ischemia correlates with preservation of high-energy phosphates as a result of different Ca2+ channel blocking abilities under high [K+]e conditions.  (+info)

Rapid saline infusion produces hyperchloremic acidosis in patients undergoing gynecologic surgery. (6/1411)

BACKGROUND: Changes in acid-base balance caused by infusion of a 0.9% saline solution during anesthesia and surgery are poorly characterized. Therefore, the authors evaluated these phenomena in a dose-response study. METHODS: Two groups of 12 patients each who were undergoing major intraabdominal gynecologic surgery were assigned randomly to receive 0.9% saline or lactated Ringer's solution in a dosage of 30 ml x kg(-1) x h(-1). The pH, arterial carbon dioxide tension, and serum concentrations of sodium, potassium, chloride, lactate, and total protein were measured in 30-min intervals. The serum bicarbonate concentration was calculated using the Henderson-Hasselbalch equation and also using the Stewart approach from the strong ion difference and the amount of weak plasma acid. The strong ion difference was calculated as serum sodium + serum potassium - serum chloride - serum lactate. The amount of weak plasma acid was calculated as the serum total protein concentration in g/dl x 2.43. RESULTS: Infusion of 0.9% saline, but not lactated Ringer's solution, caused a metabolic acidosis with hyperchloremia and a concomitant decrease in the strong ion difference. Calculating the serum bicarbonate concentration using the Henderson-Hasselbalch equation or the Stewart approach produced equivalent results. CONCLUSIONS: Infusion of approximately 30 ml x kg(-1) x h(-1) saline during anesthesia and surgery inevitably leads to metabolic acidosis, which is not observed after administration of lactated Ringer's solution. The acidosis is associated with hyperchloremia.  (+info)

Evaluation of signals activating ubiquitin-proteasome proteolysis in a model of muscle wasting. (7/1411)

The ubiquitin-proteasome proteolytic system is stimulated in conditions causing muscle atrophy. Signals initiating this response in these conditions are unknown, although glucocorticoids are required but insufficient to stimulate muscle proteolysis in starvation, acidosis, and sepsis. To identify signals that activate this system, we studied acutely diabetic rats that had metabolic acidosis and increased corticosterone production. Protein degradation was increased 52% (P < 0.05), and mRNA levels encoding ubiquitin-proteasome system components, including the ubiquitin-conjugating enzyme E214k, were higher (transcription of the ubiquitin and proteasome subunit C3 genes in muscle was increased by nuclear run-off assay). In diabetic rats, prevention of acidemia by oral NaHCO3 did not eliminate muscle proteolysis. Adrenalectomy blocked accelerated proteolysis and the rise in pathway mRNAs; both responses were restored by administration of a physiological dose of glucocorticoids to adrenalectomized, diabetic rats. Finally, treating diabetic rats with insulin for >/=24 h reversed muscle proteolysis and returned pathway mRNAs to control levels. Thus acidification is not necessary for these responses, but glucocorticoids and a low insulin level in tandem activate the ubiquitin-proteasome proteolytic system.  (+info)

Changes in intracellular Na+ and pH in rat heart during ischemia: role of Na+/H+ exchanger. (8/1411)

The role of the Na+/H+ exchanger in rat hearts during ischemia and reperfusion was investigated by measurements of intracellular Na+ concentration ([Na+]i) and intracellular and extracellular pH. Under our standard conditions (2-Hz stimulation), 10 min of ischemia caused no significant rise in [Na+]i but an acidosis of 1.0 pH unit, suggesting that the Na+/H+ exchanger was inactive during ischemia. This was confirmed by showing that the Na+/H+ exchange inhibitor methylisobutyl amiloride (MIA) had no effect on [Na+]i or on intracellular pH during ischemia. However, there was a short-lived increase in [Na+]i of 8.2 +/- 0.6 mM on reperfusion, which was reduced by MIA, showing that the Na+/H+ exchanger became active on reperfusion. To investigate the role of metabolic changes, we measured [Na+]i during anoxia. The [Na+]i did not change during 10 min of anoxia, but there was a small, transient rise of [Na+]i on reoxygenation, which was inhibited by MIA. In addition, we show that the Na+/H+ exchanger, tested by sodium lactate exposure, was inhibited during anoxia. These results show that the Na+/H+ exchanger is inhibited during ischemia and anoxia, probably by an intracellular metabolic mechanism. The exchanger activates rapidly on reperfusion and can cause a rapid rise in [Na+]i.  (+info)

A total of 1,805 dogs and cats were included; of these, 887 (49%) were classified as having a metabolic acidosis (753 dogs and 134 cats). Primary metabolic acidosis was the most common disorder in dogs, whereas mixed acid base disorder of metabolic acidosis and respiratory acidosis was most common in cats. Hyperchloremic metabolic acidosis was more common than a high anion gap (AG) metabolic acidosis; 25% of dogs and 34% of cats could not be classified as having either a hyperchloremic metabolic acidosis or a high AG metabolic acidosis ...
The objective of this experiment was to examine the effect of Subacute Ruminal Acidosis (SARA) on milk fatty acid (FA) profiles with emphasis on odd-chain and branched-chain FA. Sixteen multiparous Holstein dairy cows (618±35 kg of body weight, 221±32 days in milk) were used in a randomized complete-block design. During week 1, all cows received a high-forage diet (90% chopped grass hay, 5% grain mix, 5% protein supplement, dry-basis; HF). During weeks 2 through 4, cows either continued receiving the HF diet or received a low-fiber diet (38% chopped grass hay, 57% grain mix, 5% protein supplement, dry-basis; LF). Milk yield and dry matter intake were recorded daily, milk samples were collected twice weekly and ruminal pH was continuously recorded during the last 48 h of each week. Statistical analysis was conducted on weekly measuring Proc Mixed of SAS accounting for repeated measurement. The model included the fixed effects of diet, week, their interaction and block. Helmert contrasts were used
We have acid all around us. Weve got acid rain, acid reflux, and acid rock. Theres acidophilus, antacids, and acidic comments. Im not trying to get "Forrest Gump" on you; the destination for this rant is the fact that many acids around us are hidden. The acids Im referring to are acids hidden in what we put in our bodies, posing as nutrition. Im talking about acids that rob us of our good health; that affect our quality of life. These acids, when left unchecked, can bring about an unhealthy state of tune in our bodies. Mind you, Im not talking death here (at least not immediately); Im sharing the type of acid effects that sneak up on you quietly, like a thief in the night. This insidious acid health condition is called low-grade, chronic acidosis. Im trying to stir your pot a little, because you should be angry about what causes this "under-the-radar" condition. Everyone should be furious about what isnt being done to stop it!. Low grade, chronic acidosis isnt something thats going to ...
The prevalence of subacute ruminal acidosis (SARA) was determined in 197 dairy cows in 18 herds in the Dutch province of Friesland. Samples of rumen fluid were taken by rumenocentesis from between five and 19 animals on each farm and the pH of each sample was determined. The body condition of 139 of the cows was scored approximately three weeks before they calved and three weeks after they calved. The overall prevalence of SARA was 13·8 per cent, and the prevalence on individual farms ranged between 0 per cent (on seven of the farms) and 38 per cent (on one farm). The stage of lactation did not influence the prevalence of SARA but the cows with the condition lost more body condition over the calving period.. ...
Introduction Acute metabolic acidosis of non-renal origin is usually a result of either lactic or ketoacidosis, both of which are associated with a high anion gap. There is increasing recognition, however, of a group of acidotic patients who have a large anion gap that is not explained by either keto- or lactic acidosis nor, in most cases, is inappropriate fluid resuscitation or ingestion of exogenous agents the cause. Methods Plasma ultrafiltrate from patients with diabetic ketoacidosis, lactic acidosis, acidosis of unknown cause, normal anion gap metabolic acidosis, or acidosis as a result of base loss were examined enzymatically for the presence of low molecular weight anions including citrate, isocitrate, ?-ketoglutarate, succinate, malate and d-lactate. The results obtained from the study groups were compared with those obtained from control plasma from normal volunteers. Results In five patients with lactic acidosis, a significant increase in isocitrate (0.71 ± 0.35 mEq l-1), ...

Delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether a mixed acid base disorder (metabolic acidosis) is present. The anion gap (AG) is calculated first and if an anion gap is present, results in either a high anion gap metabolic acidosis (HAGMA) or a normal anion gap acidosis (NAGMA). A low anion gap is usually an oddity of measurement, rather than a clinical concern. The equation for calculating the Delta Ratio is: (AG - 12) ___________ (24 - [HCO3¯]) and reflects either an increase in the anion gap or a decrease in the bicarbonate concentration ([HCO3¯]). The ratio gives one of four results: 1. < 0.4 due to a pure NAGMA 2. 0.4 - 0.8 due to a mixed NAGMA + HAGMA 3. 0.8 - 2.0 due to a pure HAGMA 4. >2.0 due to a mixed HAGMA + metabolic alkalosis (or pre-existing compensated respiratory acidosis) Results 2 and 4 are the ones which have mixed acid-base disorders.

Extracellular tumor acidosis largely results from an exacerbated glycolytic flux in cancer and cancer-associated cells. Conversely, little is known about how tumor cells adapt their metabolism to acidosis. Here, we demonstrate that long-term exposure of cancer cells to acidic pH leads to a metabolic reprogramming toward glutamine metabolism. This switch is triggered by the need to reduce the production of protons from glycolysis and further maintained by the NAD(+)-dependent increase in SIRT1 deacetylase activity to ensure intracellular pH homeostasis. A consecutive increase in HIF2α activity promotes the expression of various transporters and enzymes supporting the reductive and oxidative glutamine metabolism, whereas a reduction in functional HIF1α expression consolidates the inhibition of glycolysis. Finally, in vitro and in vivo experiments document that acidosis accounts for a net increase in tumor sensitivity to inhibitors of SIRT1 and glutaminase GLS1. These findings highlight the ...
Intensive care treatment of severe mixed metabolic acidosis.: We report a case of severe metabolic acidosis associated with acute renal failure and septicaemia
As mentioned above there is a lag period between introducing a new diet and the rumen adjusting to more efficiently utilise the new diet. Studies have shown that the rumen papillae respond to dietary changes by changing size and shape in order to increase or decrease the surface area of the rumen wall and thus speed up or slow down absorption of nutrients. It is estimated that a period of about 4-6 weeks is required before papillae adjust to a new diet and consequentially prevent acid build up. Microbial populations have also been observed adjusting to changes in diet and may also be responsible for the lag period. It is recommended that cows switching to a high grain diet be transitioned slowly by gradually increasing their grain intake and therefore allow the rumen to adapt to the new diet.. One of the major problems with high grain diets is the lack of rumination it causes and therefore the lack of saliva produced. Saliva production in cows can easily exceed 100 litres a day and is essential ...
NH3 production by renal cortical mitochondria was studied under conditions of metabolic acidosis induced in vivo and with pH manipulations of the media bathing mitochondria from normal rats. A HCO3- medium equilibrated with O2 and CO2 was utilized with glutamine concentrations of either 10 or 0.5 mM. With chronic acidosis NH3 production increased significantly at either substrate concentration. Similar results were obtained with rotenone in the media, both with chronic acidosis and with acidosis of 3 h duration, indicating that increased glutamine entry and/or phosphate-dependent glutaminase (PDG) activity accounts for the increased ammoniagenesis. In contrast to acidosis induced in vivo, mitochondria from normal rats subjected to a diminution in medium pH, either by manipulation of HCO3 concentration or PCO2, significantly decrease NH3 production. Mitochondrial studies with rotenone, as well as studies of solubilized PDG, suggest that a low pH diminishes NH3 production by directly altering PDG activity

Metabolic acidosis is a primary reduction in bicarbonate, typically with a compensatory reduction in carbon dioxide partial pressure (Pco2); pH may be markedly low or slightly subnormal. Metabolic acidosis is categorized as high or normal anion gap based on the presence or absence of unmeasured anions in serum. The condition of metabolic acidosis occurs when…
A system of continual data acquisition of feed intake and ruminal pH has been developed for studying subacute acidosis in finishing steers. Feed intake is monitored with feedbunks which are suspended from weigh cells. Ruminal pH is monitored with submersible pH electrodes suspended in the rumen. Numerous anecdotal observations of subacute acidosis have been made throughout the feeding periods of several steers, providing information unlikely to be recognized during a planned trial. Therefore, this model for studying subacute acidosis offers many unique opportunities for enhancing our understanding of the interactions between feed intake and acidosis.
Results did not allow risk reduction and NNT to be calculated. Previous studies of administering parenteral fluid and/or alkali therapy to neonates with metabolic acidosis have included infants with clinically suspected poor perfusion (e.g. low blood pressure, poor cutaneous perfusion). Other studies of the effect of early volume expansion on mortality and morbidity have included unselected preterm infants not known to have metabolic acidosis. We found only two studies addressing the benefit of administering intravenous bolus of albumin or normal saline to normovolaemic neonates with metabolic acidosis. They do not however provide a clear answer to the main question of this article in view of few methodological weaknesses. The first study was not blinded.

Metabolic acidosis is a disorder frequently encountered in emergency medicine and intensive care medicine. As literature has been enriched with new data concerning the management of metabolic acidosis, the French Intensive Care Society (Société de Réanimation de Langue Française [SRLF]) and the French Emergency Medicine Society (Société Française de Médecine dUrgence [SFMU]) have developed formalized recommendations from experts using the GRADE methodology. The fields of diagnostic strategy, patient assessment, and referral and therapeutic management were addressed and 29 recommendations were made: 4 recommendations were strong (Grade 1), 10 were weak (Grade 2), and 15 were experts opinions. A strong agreement from voting participants was obtained for all recommendations. The application of Henderson-Hasselbalch and Stewart methods for the diagnosis of the metabolic acidosis mechanism is discussed and a diagnostic algorithm is proposed. The use of ketosis and venous and capillary ...
BACKGROUND: Patients presenting with diabetic ketoacidosis (DKA) are hypovolemic, hyperglycemic, and acidotic. First line therapy is administration of resuscitation crystalloid fluids to increase systemic pressure for maintenance of tissue perfusion. Volume repletion can be measured by monitoring several physiological indicators including mean arterial pressure (MAP) and urine output (UO), where an increase of both indicate an improvement in volume status. The crystalloid fluid recommended by the American Diabetes Association (ADA) is normal saline (NS) because it has a track record of being a safe option. However, administration of NS can induce hyperchloremic metabolic acidosis (HMA) in many patients receiving it for rapid and large volume fluid replacement in a spectrum of circumstances and in most who receive it for DKA. An alternate crystalloid, Plasma-Lyte, is a balanced electrolyte solution (BES) with composition similarities to plasma, therefore it has less potential to cause biochemical changes
article{8816f1fb-c286-4fc9-98d2-89f14c3766ab, abstract = {,p,Hypoxia and acidosis are inherent stress factors of the tumor microenvironment and have been linked to increased tumor aggressiveness and treatment resistance. Molecules involved in the adaptive mechanisms that drive stress-induced disease progression constitute interesting candidates of therapeutic intervention. Here, we provide evidence of a novel role of heparan sulfate proteoglycans (HSPG) in the adaptive response of tumor cells to hypoxia and acidosis through increased internalization of lipoproteins, resulting in a lipid-storing phenotype and enhanced tumor-forming capacity. Patient glioblastoma tumors and cells under hypoxic and acidic stress acquired a lipid droplet (LD)-loaded phenotype, and showed an increased recruitment of all major lipoproteins, HDL, LDL, and VLDL. Stress-induced LD accumulation was associated with increased spheroid-forming capacity during reoxygenation in vitro and lung metastatic potential in vivo. On a ...
Acidosis is a major factor that determines the upper limit of exercise endurance. We have previously shown that anions usually associated with intermediary metabolism are elevated in critically ill patients with metabolic acidosis and contribute significantly to acidosis generation. This study was to determine whether volunteers with normal metabolism would exhibit similar elevations in anions associated with intermediate metabolism when exposed to a short-term physiological stress leading to a brief lactic acidosis. Physiological stress was induced on five healthy male subjects by means of a ramped exercise protocol. Blood was obtained immediately prior to and post-exercise, plasma ultrafiltrate was prepared and analysed immediately both by enzyme assay and liquid chromatography coupled to electrospray-mass spectrometry (LC/ESI-MS). Metabolic acidosis concomitant with a significant increase in blood lactate occurred in each subject, but in addition, anions normally associated with intermediate ...
Subacute ruminal acidosis (SARA) is one of many challenges that a dairy cow can face during her lactation, affecting not just milk production, but also general health and longevity. Though not easily detected, SARA can have a serious impact on dairy production.
OBJECTIVES: Infants who develop encephalopathy after perinatal asphyxia have an increased risk of death and adverse neurologic outcome. Conflicting results exist concerning outcome in healthy infants with metabolic acidosis at birth. The aim of the current study was to evaluate whether metabolic acidosis at birth in term infants who appear healthy is associated with long-term developmental abnormalities. METHODS: From a population-based cohort (14 687 deliveries), 78 infants were prospectively identified as having metabolic acidosis (umbilical artery pH , 7.05 and base deficit in the extracellular fluid .12.0 mmol/L). Two matched controls per case were selected. The child health and school health care records were scrutinized for developmental abnormalities. RESULTS: Outcome measures at 6.5 years of age for 227 of 234 children (97%) were obtained. No differences were found concerning neurologic or behavioral problems in need of referral action or neurodevelopmental diagnosis in comparison of ...

Metabolic acidosis is an acid-base disorder characterized by a decrease in serum pH that results from either a primary decrease in plasma bicarbonate concentration ([HCO3 -]) or an increase in hydrogen ion concentration ([H+]). It is not a disease but rather a biochemical abnormality.
The pH level of urine after 6 hours of rest reflects pH throughout the body. Levels below 6.5 indicate metabolic acidosis. Low pH also suggests mineral deficits, because minerals are pulled from bone and body fluid during metabolic acidosis to buffer and reduce acids and maintain pH within a health range.. Acid-alkaline balance is important. Tiny changes in pH have profound implications for cell metabolism. Life exists poised exquisitely just above the neutral point of 7.0. Levels of pH above 7.5 can indicate catabolic illness in which amino acids are used as energy sources.. Any unusual variation in urinary pH is usually reflected in the first morning urine. This calls for changes in diet and/or nutritional supplements to restore acid-alkaline balance. Simply checking the pH level each day provides ongoing monitoring to see whether pH has been corrected. (Click here for 1st AM Urine pH test protocol) This is an important aspect of biochemistry - so if there is an abnormality, that has to be ...

The results of this investigation demonstrate that a 2°C to 3°C reduction in intraischemic brain temperature is associated with potentially important alterations in ischemic brain metabolism and subsequent partial neuroprotection in comparison to animals studied under normothermic conditions. As indicated by the group effect, intraischemic modest hypothermia resulted in higher pHi values consistently during ischemia and for at least 30 minutes after ischemia compared with normothermic animals. Although the magnitude of difference in pHi between groups is in the order of 0.15 to 0.20 pH units, the persistence of this finding during an interval of approximately 45 minutes may be critical in attenuating potential adverse effects of brain acidosis. Among animals of both groups, clinical and histological evidence of brain injury were associated with more severe intraischemic acidosis. The results suggest that brain acidosis may be critical in the pathogenesis of neonatal ischemic brain damage, and ...

Severe metabolic acidosis developed after the operation, and the patient died 6 hours after surgery. Autopsy showed thromboembolism of the superior mesenteric artery and aortic dissection in the descending thoracic aorta because of stent graft insertion into a false lumen. To reduce complications like this case, we should consider the peculiar anatomic features and thoroughly evaluate atheromatous changes in the aortic wall with improvement of the shape of the sheath and delivery system ...
Rumen health is of vital importance in ensuring healthy and efficient dairy cattle production. Current feeding programs for cattle recommend concentrate-rich diets to meet the high nutritional needs of cows during lactation and enhance cost-efficiency. These diets, however, can impair rumen health. The term "subacute ruminal acidosis" (SARA) is often used as a synonym for poor rumen health. In this review, we first describe the physiological demands of cattle for dietary physically effective fiber. We also provide background information on the importance of enhancing salivary secretions and short-chain fatty acid absorption across the stratified squamous epithelium of the rumen; thus, preventing the disruption of the ruminal acid-base balance, a process that paves the way for acidification of the rumen ...

Concentrations of ketone bodies (beta-hydroxybutyrate [[3OHB] and AcAc) are elevated in DKA. The serum bicarbonate concentration is low because bicarbonate is used as a buffer against metabolic acidosis, which results in increased anion gap acidosis. Some degree of hyperchloremic acidosis frequently coexists with increased anion gap acidosis in DKA [47], and the anion gap reflects the combination of these processes. Although concentrations of 3OHB and AcAc are elevated in patients who have DKA, the ratio of 3OHB:AcAc is increased during DKA as a result of changes in the redox potential (NADH/NAD+ ratio) in hepatic mitochondria [59]. Although the ratio of 3OHB:AcAc is typically 1:1 in anormal individual, this ratio rises to as high as 10:1 in persons who have DKA. These changes are important mainly because the nitroprusside reaction used to test urine ketone concentrations detects only AcAc and not 3OHB. Although urine testing can be relied on to help diagnose DKA, the urine ketone concentration ...

The obvious question arising from protocol 1 is, Does the cardioprotection seen with brief exogenous calcium infusion and ischemic preconditioning share a common pathway? Considerable evidence indicates that transient, nonlethal episodes of ischemia are associated with brief, transient, and reversible increases in cytosolic calcium concentrations.9 10 12 13 14 Calcium influx during brief ischemia is, at least in part, a secondary consequence of intracellular acidosis: the increase in intracellular concentrations of H+ stimulates Na+-H+ exchange, resulting in the extrusion of H+, influx of Na+, and subsequent increase in intracellular calcium via Na+-Ca2+ exchange.11 12 13 15 The importance of this pathway may diminish during prolonged ischemia, because extrusion of H+ and resultant extracellular acidosis serve to inhibit Na+-H+ exchange. However, reperfusion and the resultant washout of extracellular H+ rapidly reactivate Na+-H+ exchange, thereby restoring normal pH at the price of Na+ and ...
In this clinical summary, Dr. Elizabeth Sekul of the Medical College of Georgia discusses hemorrhagic shock and encephalopathy syndrome (HSES), a rare disorder that primarily affects infants younger than 1 year of age. It is often fatal despite intensive medical care, and rarely do those who survive escape severe neurologic impairment. There are no biological markers for HSES. The diagnosis rests on the recognition of its clinical and laboratory abnormalities. The hallmarks of the disorder are abrupt onset of high fever, shock, encephalopathy, seizures, coagulopathy, and renal and hepatic dysfunction. Laboratory abnormalities, including progressive decline in hematocrit and platelets and rising transaminases and creatine phosphokinase, are noted and tend to peak in the first 36 hours. Severe acidosis is typical at presentation. Onset tends to be at night to early morning hours and more often in the winter months. Overall incidence is unknown..

We tested the hypothesis that in humans, metabolic acidosis can disorder the metabolism of 1,25-dihydroxyvitamin D [1,25(OH)2D] by impairing the capacity for a sustained physiological stimulus to increase renal production of this hormone. Specifically, in seven healthy men in whom restriction of dietary phosphorus had doubled their serum concentration of 1,25(OH)2D, we induced metabolic acidosis of moderate severity with oral NH4Cl, administered for 7 days. With induction of acidosis, the serum concentration of 1,25(OH)2D decreased sharply and remained decreased and near constant throughout the period of acidosis, the decrease amounting to one-half of the increment induced by phosphorus restriction alone. The serum concentration of free 1,25(OH)2D also decreased, since the measured free fraction of 1,25(OH)2D was unaffected by NH4Cl. The decrease in serum 1,25(OH)2D was accounted for by a 16% increase in its metabolic clearance rate and by a 19% decrease in its production rate. Metabolic ...
This case provided a useful insight into some of the controversies surrounding the treatment of profound lactic metabolic acidosis. A review of the evidence showed that there seems to be good evidence and consensus for not using bicarbonate therapy to treat acidosis with a pH more than 7.2, but below this opinion is divided. It illustrated the need to look at each case on its individual merits, some of the alternative therapies that may become available, and to continue to review emerging literature in what continues to be a controversial area. ...

We appreciate Isley and Okis comments. The writers point out that our patients liver dysfunction may be related to hypotension. A similar point was made by Freid and colleagues from SmithKline Beecham in a letter appearing in the same issue as our report (1). The SmithKline Beecham group describes the patients hypotension and requirement of intensive support in detail. However, it is important to note that the patients profound liver function abnormalities were documented as being present before the hypotension developed. At the time initial blood studies were obtained, the patient was normotensive and had no physical examination or chest radiograph findings of congestive heart failure. In addition, our patient had experienced several weeks of hepatitis-like symptoms before presentation. Liver failure-induced metabolic acidosis may have caused his subsequent cardiac decompensation. We believe that the patients temporal course is more consistent with the primary development of liver ...

In my video Alkaline Diets, Animal Protein, and Calcium Loss I presented evidence challenging the notion that our body is buffering the acid formed from our diet with calcium from our bones. How then is our body neutralizing the acid? Maybe with our muscles! Our blood gets more acidic as we age and our kidney function declines, and this may be a reason we lose muscle mass as we get older. As a pair of researchers note: "The modern Western diet based on animal products generates an acid load that may cause a lifespan state of unnoticed and growing metabolic acidosis." This chronic low-level diet-dependent metabolic acidosis might contribute to the progressive shrinking of our muscle mass as we age.. Muscle wasting appears to be an adaptive response to acidosis. When our muscles break down, amino acids are released into the bloodstream. Our liver can then take these amino acids and make something called glutamine, which our kidneys can use to get rid of excess acid. And indeed, in a three year ...

Water has a neutral pH of 7. Blood has a pH of 7.35 to 7.45, slightly alkaline. Your body fights hard to neutralize acids and maintain the proper pH in organs, tissues and body fluids. But it can only do that for so long before a condition known as acidosis occurs. You have to give the body what it needs, in the form of alkalizing fruits and vegetables, so that it can properly maintain the delicate acid base balance.. Dr. Robert Young says health depends on an internal alkaline environment. In his book, "The pH Miracle," Young discusses the importance of regulating your bodys acid/alkaline chemistry and how it can result in weight loss, increased stamina and strength, and a stronger immune system. ...

A pregnant patient has pneumonia. There are also concerns that she has a metabolic acidosis. Can you solve this metabolic muddle?
When acidosis is present on blood tests, the first step in determining the cause is determining the anion gap. If the anion gap is high (>12 mEq/L), there are several potential causes. High anion gap metabolic acidosis is a form of metabolic acidosis characterized by a high anion gap (a medical value based on the concentrations of ions in a patients serum). An anion gap is usually considered to be high if it is over 12 mEq/L. High anion gap metabolic acidosis is caused generally by acid produced by the body,. More rarely, high anion gap metabolic acidosis may be caused by ingesting methanol or overdosing on aspirin. The Delta Ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present. The list of agents that cause high anion gap metabolic acidosis is similar to but broader than the list of agents that cause a serum osmolal gap. Causes include: The newest mnemonic was proposed in The Lancet ...

The molecular mechanism of pH sensing by chemoreceptors is not clear, although it had been proposed to be mediated by a drop in intracellular pH of carotid body glomus cells, which inhibits a K+ current. Recently, pH-sensitive ion channels have been described in glomus cells that respond directly to extracellular acidosis. In this study, we investigated the possible molecular mechanisms of carotid body pH-sensing by recording the responses of glomus cells isolated from rat carotid body to rapid changes in extracellular pH using whole-cell patch-clamping technique. Extracellular acidosis evoked transient inward currents in glomus cells that were evident at pH 7.0 and half-activated (pH 50) at 6.3. The current had the characteristics of ASICs. It averaged 40.7±15.7 pA (n=5) at pH 5.0 and was blocked by the ASIC channel blocker amiloride (200 μm) to 2.5±1.6 pA. Na+ free bathing solution eliminated the current and a Ca2+ free buffer enhanced (P,0.05) the current at pH 6.0 from 18.5±2.2 to ...
