To evaluate the effects of hypertonic saline and gelatin solutions on plasma lactate concentration and serum electrolytes following experimental endotoxemia, twenty sheep were randomly divided into 4 groups: the negative control, positive control, hypertonic saline and gelatin. Endotoxaemia was induced in the gelatin, hypertonic and positive control groups by intravenous administration of lipopolysaccharide (LPS) from E. coli serotype O55:B5 at 0.1 µg/kg. Serum lactate and electrolytes were measured 30 min before and 30 min after LPS injection, as well as on mins 90 after LPS injection, 30, 60, 90, 120, 150, 180 and 240 min after injection of the solutions. The results showed that plasma lactate significantly increased immediately after endotoxemia induction but a significant decrease was observed in the hypertonic saline group on 90 minutes after injection and in the gelatin group 60 minutes after injection. Serum potassium concentration after endotoxemia induction was significantly decreased compared to the negative control group and also decreased significantly after 90 min. Serum sodium and calcium concentrations decreased after induction of endotoxemia and increased after treatment with solutions. Serum phosphorus concentration increased with induction of endotoxemia and decreased after injection of solutions. In this study, it was found that hypertonic saline and gelatin solutions make blood lactate and electrolytes close to normal after induce of experimental endotoxemia in sheep model.

Plasma biochemical parameters are important aspects in the management of endangered species. The values of these parameters can be used for confirming the maturity and for monitoring any changes in the quality of waters and related soils.The aim of this research was to investigate the reference values of biochemical factors in sea bream (Acantopagrus latus) and grouper (Epinephelus coioides). Blood samples (30 grouper and 30 sea bream) were collected from captured fish from coastal waters of Chabahar (Ramin waterfront). Plasma levels of glucose, Blood Urea Nitrogen (BUN), cholesterol (CHO), triglyceride, total protein, albumin, calcium (Ca2), phosphorus (P), sodium (Na), bilirubin and potassium (K) were measured. The plasma levels of different biochemical values in A. latus and E. coioides were Na (328.50± 32.03, 271.90±27.88), K (2.12±0.42, 3.43±0.39), Ca2(19.80±2.97, 16.80±2.34),P (2.35±0.40, 2.40±0.57)(mmol/l)and CHO (257.30±35.51, 137.30±42.11),triglyceride (102.02±11.82, 68.10±15.34), BUN (3.82±0.55,2.66±0.45), bilirubin (0.24±0.04, 0,44±0.13), glucose (44.25±16.18, 43.70±10.11) (mg/dl), protein (4.31±0.32, 3.92±0.36) and albumin (0.15±0.03, 0.36±0.05) (g/dl) respectively. It can be concluded that the values of blood biochemical parameters is may be affected by It can be concluded that the studied parameters may be affected by physiological factors such as the species of fish.

Serum biochemical parameters are important aspects in the management of endangered species. The values of these parameters can be used for confirming the maturity and for monitoring any changes in the quality of waters and related soils. The aim of present study was to investigate some of blood serum biochemical parameters in immature females and males of Argyrosomus hololepidotus. Blood samples were collected from twenty captured fish from coastal waters of Chabahar (Ramin waterfront). Serum levels of glucose، blood urea nitrogen (BUN)، cholesterol (CHO)، triglyceride، bilirubin، total protein، albumin، phosphorus (P)، sodium (Na)، potassium (K)، calcium (Ca) and alkaline phosphatase (ALP) were determined as Mean±SD in immature males and females. The levels of different biochemical parameters in males and females were respectively as follows; Na (239. 50±17. 06، 257. 80±20. 80)، K (3. 87±0. 98، 1. 94±0. 49)، P (2. 73±0. 39، 2. 79±0. 53)، Ca (2. 89±0. 47، 1. 56±0. 32) (mmol/l)، glucose (71±10. 33، 24. 04±2. 50)، bilirubin 0. 46±0. 11، 0. 24±0. 05)، ALP (68. 30 ±124. 17، 244. 50±68. 98) (Iu/l)، BUN (1. 94±0. 50، 0. 63±0. 29)، triglyceride (94. 70±9. 56، 32. 85±7. 56)، CHO (13. 02±2. 69، 4. 94±3. 29) (mg/dl)، total protein (1. 65±0. 51، 3. 15±0. 86) and albumin (0. 44±0. 16، 0. 12±0. 04) (g/dl). The results showed that the serum levels of Na and total protein in females were significantly higher than males and there were significant differences in all of the serum values (except P) between males and females (P<0. 05). It can be concluded that the values of blood biochemical parameters may be affected by sex of fish.

Hematologic changes and serum biochemical analysis of 20 naturally infected and 15 non-infected calves with theileria annulata were carried out. Theileriosis was confirmed by observing theileria merosoites in red blood cells of peripheral blood smears of calves. Two blood samples were taken from the jugular vein in disposable polyethylene tubes one with anticoagulant (EDTA) for hematology and another 10 ml without anticoagulant substance for biochemical analysis. Compare the results the patient and control groups performed with Spss software and "t" test in the P<0.05. The results of this study showed that hematocrit, hemoglobin, red blood cells (RBC) count, platelets count and serum total protein were significantly reduced in calves infected with theileria (infected calves) compared with healthy calves (control group). Calcium, magnesium and glucose concentrations were also decreased in infected calves, but this was significant only in calcium. Phosphorus concentration had increased but this was not significant statistically. The results of present study shows that theileriosis in calves causes significant decrease in serum calcium which as new finding special attention should be paid when treating animals in addition to the disease specific treatment.

This research was conducted to determine some blood serumic electrolytes and enzymes in apparently healthy mules living in temperate geographical conditions of northwestern Iran and the effect of age and sex on these parameters. The studied animals (51 males and 48 females) which ranged in age from 4 to 12 yaers, were divided into three similar age groups. The serumic values of sodium (mmol/L), potassium (mmol/L), chloride (mg/L), phosphorous (mg/L), and activities of AST (IU/L), ALT (IU/L), ALP (IU/L), GGT(IU/L) and CPK(IU/L) were 137.55±6.02, 4.06±0.55, 104.01±3.46, 2.69±0.35, 409.95±44.82, 17.96±2.25, 510.83±70.24, 31.27±4.52 and 295.56±38.76 respectively. Gender had no significant effect on the studied parameters (p>0.05). There were significant differences between different age groups (p

Changing in protein level and electrolyte balance in diets can be useful in improvement of performance in broilers exposed to heat stress. This experiment was carried out to determine the effects of different levels of protein and electrolyte balance (DCAB) on performance and carcass traits in broiler exposed to heat stress. 486 Ross, one-day old broilers were used in a completely randomized design with a 3×3 factorial arrangement in triplicate for a treatment. For performing this, 9 diets were formulated according to NRC recommendation with 3 different protein levels (100, 90 and 80% of NRC recommendations) and electrolyte balance (200, 260 and 320meq/kg). The birds were exposed to heat stress (34±3ºC) for 8 hours (10:00 to 18:00). Body weight gain in broilers fed containing 260meq/kg DCAB, were significantly (p<0.05) higher than those fed other levels of DCAB in other periods (starter, grower and total period). The electrolyte balance had significant effect (p<0.05) on feed intake in grower period (14.63gr/day). Dietary protein levels had no significant effect on body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) in all periods. There was a significant interaction (p<0.05) between DCAB and protein levels on the BWG an FI (11.5 and 21.11gr/day). Compared to DCAB 320meq/kg, the DCAB 200 and 260meq/kg significantly decreased FCR (0.15 and 0.2, respectively), but FCR did not affect by protein levels. Dietary DCAB had significant effect (p<0.05) on carcass yield (3.25%), breast (1.63%) and relative weights of liver (0.26%) and gizzard (0.56%), but had no significant effect on thigh, heart and abdominal fat. The lower protein level did not affect on carcass traits, with the exception of carcass yield. 260 meq/kg DCAB and medium 90% protein level of NRC recommendation in heat stress can be used.

Reference values of serum parameters are important markers in health evaluation and diagnosis of diseases, as well as in controlling biological processes in aquatic animals. The aim of this research was to determine the reference values of biochemical factors in breeding Rutilus frisii kutum. Blood samples were collected from captured fish from Tajan River. Serum levels of glucose, BUN, creatinine, cholesterol, triglyceride, direct bilirubin, total protein, albumin, calcium (Ca), phosphorus (P), sodium (Na), and potassium (K) were measured. The serum levels of different biochemical values in males and females were as follows: Na for males 387.1±11.5 mmol/L, and females 420.7±7.1 mmol/L; K for males 39.9±10.6 mmol/L, and for females 37.9±7.4 mmol/L; P for males 19.2±1.0 mg/dl, and females 28.9±2.8 mg/dl; Ca for males 15.9±1.5mg/dl, and for females 21.6±1.0 mg/dl; glucose for males 209.8±23.2 mg/dl, and for females 83.8±11.3mg/dl; cholesterol for males, 472.6±23.6mg/dl, and for females 306.6±22.9 mg/dl; triglyceride for males 393±23.3mg/dl, and for females 275.1±9.2mg/dl; total bilirubin for males 0.4±0.02mg/dl, and for females 0.3±0.02mg/dl; direct bilirubin for males 0.1±0.03mg/dl, and for females 0.1±0.02mg/dl; BUN for males 22.3±1.0mg/dl, and for females 24.1±1.1mg/dl; creatinine for males 0.5±0.1mg/dl, and for females 0.7±0.1 (mg/dl); total protein for males 5.8±0.5g/dl, and for females 4.4±0.5g/dl; albumin for males 3.3±0.2g/dl, and for females 3.0±0.2 (g/dl). The current results indicate that there are significant differences in serum values of glucose, cholesterol, total bilirubin, direct bilirubin, triglyceride, phosphorus, sodium and calcium between males and females. The serum levels of cholesterol, triglyceride (p<0.001), glucose, total bilirubin (p<0.01) and direct bilirubin (p<0.05) in males, and those of phosphorus, calcium (p<0.01) and sodium (p<0.05) in females were significantly higher as compared to the opposite sexes. It can be concluded that the studied parameters may be affected by physiological factors such as the sex of fish.

This study was conducted on 40 calves under the age of one mouth with 30 calves affected by diarrhea allocated to 3 treatment groups of 10 calves each and the control group consisting of 10 calves. The control group received neither treatment nor any injections. In the first treatment group, only antibiotics were administered without any fluid therapy. In the second treatment group, apart from antibiotic therapy of diarrhea, hypertonic saline solution (7.5%) was administered at a dose of 5 ml/kg as slow intravenous infusion alongside oral ORS solution whereas in the third treatment group isotonic saline solution (0.9%) was given intravenously according to the formula (Body weight × %Dehydration) alongside oral ORS solution. In all groups, clinical examination and blood sampling was undertaken at times 0, 1, 2, 8 and 24 hours following treatment. At time 0, the diarrhea had resulted in clinical and laboratory signs such as a fever, the dehydration, tachycardia, oligopnea, increased packed sell volume, hypernatremia, hyperchloremia, hyperkalemia, hyperphosphatemia, hypercalcemia, increased serum creatinine and BUN values. Following treatment, fever subsided and the dehydration was corrected and this correction occurred faster in calves which had received hypertonic saline solution. Correction of sodium, potassium, chloride, phosphorus and calsium imbalance occurred faster in patients which were treated by hypertonic solution. Fluid therapy with saline solutions prevented the increase in serum creatinine and BUN values. In conclusion, the administration of hypertonic saline solutions leads to much faster and more reliable clinical improvement and electrolyte imbalance correction in calves affected by diarrhea.
