AbstractThe aim of this study was to evaluate the effects of two dietary supplements (monensin and a live yeast culture) on acid-base balance in steers maintained in a commercial feedlot system, considering effects over the finishing productive cycle. Steers (no. =42) were allotted randomly to one of the three study groups: (1) control group (no supplementation, C), (2) monensin supplementation (MON), and (3) live Saccharomyces cerevisiae strain 47 supplementation (SACC). Venous blood samples were collected for the measurement of acid-base parameters and l-lactate. Production parameters were also used as a complementary tool for understanding the internal changes associated with supplementation. During the finishing period, MON steers tended to gain more efficiently than C and SACC steers. In the C group, the finishing-period diet caused a progressive decline in blood bases, in line with the high-grain diet consumption. In contrast, supplemented animals did not show this trend, although lower HCO3− and base excess values were registered in SACC steers than in MON, indicating that ionophore supplementation is less effective for reducing blood base consumption than yeast supplementation. In our study, the lack of the expected response to yeast supplementation may be attributable to the high crude protein content of the ration, a common feature of commercial feedlot industries.

Abstract The characteristic for most solid tumors cells is the intracellular alkalinization and acidification of the extracellular milieu and this pH gradient inversion (pHe < pHi) is associated with tumor proliferation, invasion, metastasis, aggressiveness, and treatment resistance. However is there tumor pH (pHi and/or pHe) changes affect on venous blood plasma pH? Purpose of the study. The venous blood acid-base balance before and after the combined treatment, correlation of the venous blood pH indicators (pHb), relationship neoplasm and blood pH in patients with laryngeal cancer was study. Material and methods. Studies were performed in patients with laryngeal cancer categories T2–3 N0 M0 before and after the combined treatment. The patients were divided into four groups: Group 1 – 25 patients before the start of treatment; Group 2 – 21 patients (from Group 1) after completion of the combined treatment; Group 3 – 14 patients from Group 2 with positive results of treatment and Group 4 – 7 patients from Group 2 with a negative result of treatment (recurrence and/or metastasis of the neoplasm). The control group consisted of 15 practically healthy people (Group C). Examination of venous blood acid-base balance of patients, tumor pH and tumor cells pHi and pHe was carried. Results and discussion. The increase in pCO2 and HCO – concentration will result in decrease in the pH, but if these indicators have a clear correlation in the control group, then in patients groups there was a correlation for pHb & pCO2 and pO2 only. Besides, we marked increase in pCO2, HCO –, K+, while pO decreased in pHb after the combined treatment. It is necessary to point out the differences between some benchmarks and indicators of acid-base balance in the plasma of venous blood in primary patients and patients with recurrent laryngeal cancer. So, if pHb, pO2, and Cl– patients have statistically significant differences from control data, then differences with control pCO2 values are characteristic only for patients of Groups 1 and 3. On the contrary, differences in the HCO – indices are characteristic only for patients of Group 4. There are statistically significant differences from the control indicators K+, Na+, Ca2+, Glu, Lac, mOsm in patients of the first group and Cl– and Lac of patients in the third group. Among the indicators in the third and fourth groups of patients, statistically significant differences were noted in the values of pHb, HCO – and Glu.In patients of groups 1 and 4, the determination of pHt and the calculation of pHi, pHe revealed decrease in pHt and pHe with increasing pHi in patients with recurrence of the neoplasm.The final stage of the study was to determine the relationship (and not correlation) of blood pH and laryngeal tumors and the relationship was noted in the «pHb-tumor» system in primary patients, but in patients in 3 and 4 Groups, that «pHb-tumor» connection is rather contradictory. Conclusion. Acid-base balance indicators obviously cannot be considered as unconditional markers of carcinogenesis, but their monitoring and, in particular, venous blood pH, of patients after special treatment, can help determine the risk group of patients who may develop of a malignant neoplasm recurrence.

Aim of the study role of acid base balance in chronic severe anaemic patients admitted in Department of Medicine, Darbhanga Medical College and Hospital, Laheriasarai, Bihar. Study subject include 50 chronic and severe anaemic patients. All the fty cases underwent detailed haematological, biochemical, electrocardiographic, roentgenographic studies followed by extensive analysis of blood for blood gases and acid base parameters at the onset. Some were further studied for venous blood lactate and the effect of intravenous frusemide on the acid base parameters and the clinical state of the patient. Twenty normal controls were also studied. Work in future on the problem of chronic severe anaemia should include cases with cardiac failure and other complications like respiratory infections etc. and they should be studied for myocardial function, glomerular ltration rate and renal anion transport in addition to blood gases and acid base study as done by us. The role of ionotropic agents should be studied in such cases in isolation from that with diuretics. The administration of oxygen alone with a mask is also expected to improve almost all parameters quickly and should be studied.

Metabolic acidosis is prevalent among critically ill patients and the common cause of metabolic acidosis in ICU is lactic acidosis. However, not all ICUs can provide lactate measurement. The traditional method that uses Henderson-Hasselbach equation (completed with BE and AG) and alternative method consisting of Stewart and its modification (BDEgap and SIG), are acid-base balance parameters commonly used by clinicians to determine metabolic acidosis in critically ill patients. The objective of this study was to discover the association between acid-base parameters (BE, AGobserved, AGcalculated, SIG, BDEgap) with lactate level in critically ill patients with metabolic acidosis. This was an analytical study with a cross-sectional design. Eighty-four critically ill patients hospitalized in the ICU department Dr. M. Djamil Padang Hospital were recruited in this study from January to September 2016. Blood gas analysis and lactate measurement were performed by potentiometric and amperometric method while electrolytes and albumin measurement were done by ISE and colorimetric method (BCG). Linear regression analysis was used to evaluate the association between acid-base parameters with lactate level based on p-value less than 0.05. Fourty five (54%) were females and thirty-nine (46%) were males with participant’s ages ranged from 18 to 81 years old. Postoperative was the most reason for ICU admission (88%). Linear regression analysis showed that p-value for BE, AGobserved, AGcalculated, SIG and BDEgap were 119; 0.967; 0.001; 0.001; 0.689, respectively. Acid-base balance parameters which were mostly associated with lactate level in critically ill patients with metabolic acidosis were AGcalculated and SIG.

Abstract Pet rabbits have increased their popularity in a lot of countries. However, most of the laboratory profiles in rabbit medicine come from the observations made in rabbit as biomodels or meat production. So that further researches are necessary to obtain reference values for hematology and biochemical profiles in pet rabbits and the different breeds, especially, in relation to acid-base balance. The aim of this report was to offer the mean values of the main parameters connected with acid-base profile in Netherland Dwarf breed. Thirty-five healthy rabbits (15 males and 20 females) were studied. Venous blood sample from lateral saphenous vein was analyzed to measure: haematocrit, haemoglobin, blood urea nitrogen, glucose, blood pH, partial pressure of CO2 (pCO2), total CO2, ions bicarbonate, chloride, sodium, potassium, base excess and anion Gap. Results showed a shorter range that those reported by different researchers. Moreover, differences between genders were showed in pCO2, its values were higher in males. It may be associated with a greater cellular metabolism. Values obtained in this research should be taken into account by veterinary clinicians for this breed in their clinical assessments. Besides, these values provide new results in parameters with few reference values.

The present study deals with the use of high-grain diets with a low proportion of fodder for fattened cattle, and with the evaluation of their effect on the growth intensity and metabolic profile of the animals. Thirty Holstein &times; Czech Pied bulls were given diets containing from 86.69 to 88.54% concentrates based on crushed cereals in the period from 216<sup>th</sup> to 327<sup>th</sup> day of age. The growth intensity of bulls was high, with the average daily weight gain of 1.64 kg in the course of the whole experiment. When the average body weight of animals reached 343.67 kg and 450.93 kg, blood samples were taken from the vena jugularis of 10 randomly selected animals for the assessment of acid-base balance and selected biochemical parameters. Slightly decreased pH values and increased pCO<sub>2</sub> were detected by the assessment of acid-base balance. The calculated values of base excess and standard bicarbonate were in the reference range; however in samples of the second collection a highly significant decrease was found (P &le; 0.01). By a biochemical analysis of blood increased levels of plasma phosphorus were detected in samples of both collections in comparison with the accepted reference range. A statistically highly significant increase (P &le; 0.01) in plasma urea concentrations was detected in samples of the second collection. Other investigated parameters ranged within the accepted reference values. The results of the experiments show that high-grain diets produced intensive growth with high daily weight gains, without adverse effects on the health status of the investigated bulls. Although some depletion of compensatory mechanisms maintaining the acid-base balance was recorded, no serious disturbance of metabolic profile was registered in the animals. &nbsp;

ABSTRACT: The effects of a new intravenous electrolyte solution for veterinary therapy on electrolyte and acid-base balances of horses were evaluated, assessing the potential of the use of this solution as a rational alternative in fluid therapy. Eight healthy adult horses, including 4 males and 4 females, received two treatments in a cross-over design: isotonic saline solution (IS) and a test solution (TS) containing 145mEq of Na+, 5mEq of K+, 4mEq of Ca++, 2mEq of Mg++, 96mEq of Cl-, 60mEq of lactate, 50g of dextrose, and 4mg of cyanocobalamin per liter. Solutions were IV infused in a volume corresponding to 5% of BW, over 3 hours. Venous blood samples were taken 5 times before and after the infusion (at 0, 3, 6, 9 e 24h), for pHv, pCO2v, HCO3 -v, BEv, Na+, K+, Cl-, Ca++, Ca, P, Mg, glucose and L-lactate measurements, and AG and SID calculations. The data were analyzed through repeated measures ANOVA. The IS caused mild acidifying effect by increasing Cl- and decreasing plasma SID. In contrast, the TS induced mild and transient hypochloremia without changes in acid-base balance. Hyperglycemia was present at the end of the TS infusion and reversed 6 hours later. The horses did not exhibit any clinical changes. We concluded that TS is an option for fluid therapy in horses.

Abstract The purpose of this study was to investigate possible alterations in acid-base balance parameters and the coagulation profile in neonatal diarrheic calves. Twenty neonatal diarrheic and 20 clinically healthy neonatal calves aged between 1 week to 10 days were used. All blood samples were taken on the third day from the onset of diarrhea symptom. Venous blood samples were collected from each animal to determine platelet numbers, pH, pCO2, pO2, HCO3-, BE, O2SAT, ctCO2 and electrolytes (K+, Na+ and Cl-). Plasma samples were collected from each animal for the measurement of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), the concentrations of fibrinogen, D-dimer and the activity of antithrombin III (AT III). Blood pH (7.19), BE (-10.6 mmol/l), HCO3 - (25.15 mmol/l), pO2 (3.33 kPa), O2SAT (24.12 %) were significantly lower and serum concentration of K+ (6.55 mmol/l) was significantly higher in diarrheic calves. These changes indicate the state of uncompensated metabolic acidosis with accompanying hyperkalemia. TT (32.05s) and APTT (39.9s) values were more prolonged in calves with diarrhea than in the control group. D-dimer (587.25 μg/l) concentrations were significantly increased while a visible drop in AT III (103.75%) activity and platelets counts (598 x109/l) were observed in diarrheic group of calves. The results suggest that a consumptive type of disseminated intravascular coagulation (DIC) developed in diarrheic calves.

The aim of the study was to find the responses of acid-base parameters and performance parameters of turkeys to a corn silage (CS) diet with different values of the dietary cation-anion difference (DCAD). The turkeys were fed as follows: group A (control) – standard diet (SD) (60%) plus CS (40%); group B – SD (60%), CS (40%) plus 240 g of CaCl2 per100 kg of diet; group C – SD (60%), CS (40%) plus 480 g of CaCl2 per 100 kg of diet; group D – SD (60%), CS (40%) plus 240 g of NaHCO3 per 100 kg of diet; group E – SD (60%), CS (40%) plus 480 g NaHCO3 per 100 kg of diet. The addition of the smaller amount of CaCl2 reduced DCAD, which ranged between 49.75 ± 6.29 mEq/kg DM and 93.56 ± 3.34 mEq/kg DM. An increased content of CaCl2 led to high, negative values of DCAD. NaHCO3 supplemented in both doses resulted in a significant elevation of DCAD. The addition of CS to the SD led to a lower body weight in comparison to that in the B, C, D and E groups. Forage acidification and alkalization improves body weight gain (BWG) at every stage of feeding. Compared to the control group, the anion gap was insignificantly lower in birds exposed to the acidic diet, and was comparable to the decrease in HCO3 –. Conversely, the addition of NaHCO3 to the diet led to a marked elevation in HCO3 – to 29.63 ± 0.4 mEq/L in group D and to 30.3 ± 0.69 mEq/l in group E. In conclusion, a change in DCAD during the feeding of forage containing CS exerts stimulatory effects on productive parameters of turkeys....
