The effects of iv infusion of 7.2% NaCl (HSS, 4 ml/kg; n=6) or 7.2% NaCl in 6% dextran 70 (HSD, 4 ml/kg; n=6) followed by administration of 0.9% NaCl (ISS, 32 ml/kg) on sodium (Na), chloride (Cl), potassium (K) serum concentrations, osmolality (Osm), total protein content (TP), packed cell volume (PCV), haemoglobin concentration (Hb) and red blood cell count (RBC) were evaluated in twelve healthy sheep for 360 min. The changes in blood parametres after infusion of hypertonic and isotonic solutions were not significantly different between HSS and HSD groups. In these groups the increase in Na, Cl and Osm accompanied by the decrease in K, TP, PCV, Hb and RBC were observed at 5 min after administration of hypertonic solutions. Infusion of ISS 60 min after administration of HSS or HSD did not produce a further increase in Na, Cl and Osm, whereas K, TP, PCV, Hb and RBC decreased to the lowest values at 90 min. These results indicate that the initial bolus dose of HSS or HSD produces a rapid recruitment of extravascular fluids into the vascular compartment, whereas subsequent large volume infusion of ISS maintains intravascular blood volume expansion and does not create a risk of hypernatremia.
The aim of the research was to analyze postural deviations in Romberg’s Test in girls with idiopathic scoliosis and scoliotic posture. 28 girls aged 7-18 years old were involved in the study. Spine research was made by Exhibeon digital radiography. Based on the size of the angle of spinal curvature there were identified scoliotic posture: 1-9° and scoliosis: ≥ 10°. Postural reactions were examined by static-dynamic Tecnobody’s ST 310 Plus Stability System platform. There were 21 (75%) children with scoliotic posture, and 7 (25%) with idiopathic scoliosis. Postural reaction of FBSD was from 6.57 with opened eyes (OE) to 7.32 with closed eyes (CE). Postural reaction of MLSD was from 3.89 with opened eyes (OE) to 5.54 with closed eyes (CE). Postural reaction of AFBS was from 11.96 with opened eyes (OE) to 17.29 with closed eyes (CE). Postural reaction of AMLS was from 9.96 with opened eyes (OE) to 13.89 with closed eyes (CE). Analysis of variance with dual classification revealed a significant effect in Romberg’s Test options (OE/CE) to: Average COP X (p = 0.002264), Average COP Y (p = 0.000009), Perimeter (p = 0.000008), Ellipse Area (p = 0.029882), MediumLateral Standard Deviation X (p = 0.022162), Average ForwardBackward Speed Y (p = 0.000071) and Average Medium-Lateral Speed X (p = 0.000916). In the examination with eyes closed it has been observed a significant increase of this variances. There was no significant effects only in Forward-Backward Standard Deviation Y. Most of postural deviations did not fit the norm.
The study was carried out on two farms (A and B) involving 60 calves, aged 1—2 months, with the signs of bronchopneumonia. Calves from farm A showed severe bronchopneumonia signs (high temperature) while animals from farm В displayed signs of moderate bronchopneumonia as well as diarrhoea. In each farm the calves were divided into two equal groups. The calves of group I were treated with Bioflumeq, a soluble powder containing flumequine as an active ingredient. The calves of group II were also given antibacterial drugs for 5 days. During clinical examination lasting 7—10 days the following aspects were registered: respiratory rate, nasal discharge, cough, rectal temperature, appetite, general condition and diarrhoea. The results indicated that Bioflumeq reduced clinical signs of severe bronchopneumonia after 7 days. Better effects were observed in calves with moderate signs of bronchopneumonia and diarrhoea. The calves recovered after 5 days and diarrhoea disappeared after 3 days.
Blood acid-base, PCY and haemoglobin values and serum total protein, urea, glucose and electrolyte concentrations were determined in 51 clinically normal calves of 1-3, 4-7 and 8-10 days of age. The mean venous pH, НСОз and BE values were 7.363±0.038, 26.14±2.30 mmol/I and 0.35±2.01 mmol/l respectively between 1 and 3 days, and increased significantly to 7.386+0.036,27.46±2.80 mmol/l and 1.86+2.50 mmol/l between 4 and 10 days. The рСОз pressure did not change significantly due to age and for 1-10 day - old calves was 6.19+0.59 kPa. There were significant decreases in PCV and Hb values, from 0.32+0.05 1/1 and 102.4±11.3 g/1 to 0.29±0.04 1/1 and 97.3±15.1 g/1 respectively, between 1-3 and 4-10 days of age. The serum urea level declined from 3.12+0.79 mmol/l to 2.82±0.77 mmol/l, whereas serum inorganic phosphorus concentration elevated with increasing age from 2.26±0.33 mmol/l to 2.68±0.33 mmol/l. Serum total protein, glucose, sodium, potassium and chloride levels did not differ significantly during the first 10 days of life, and the mean values of these parameters were 56.7±10.0 g/1, 6.85±1.19 mmol/l, 133.10±9.78 mmol/l, 5.17±0.45 mmol/l and 99.43±2.63 mmol/l, respectively.
Twelve experiments were performed on 6 cannulated cows with rumen acidosis induced by intraruminal administration of saccharose in doses of 8 m 12 g/kg body weight. The pH-value, total acidity, levels of lactic and pyruvic acids, and Na, K, Cl, in organic P, Ca and Mg contents were determined in 32 samples of the rumen fluid collected before and within 4 days after the administration of saccharose. The most marked alterations in the rumen fluid were observed between 8 and 26 hours after treatment. A decrease in the rumen pH-value to 4.3 was associated with increases of lactic and pyruvic acid levels. Increases in Ca, P, Mg, and Cl and decreases in Na and K contents were noted.
Four experiments were performed in 4 cows which were fed large amount of grain feed. The food was given in a single dose or in gradually increasing doses and hay was excluded or retained in the diet. In 3 cows, symptoms of acid indigestion were observed, two of them recovered spontaneously and the third cow died on the 6th day after overeating 20 kg of ground grain barley. In these cows the following changes were found: a sudden decrease in the pH of the rumen fluid, accumulation of lactic acid in the rumen fluid and its increased concentration in the blood, increased serum inorganic phosphorus level and inereased calcium, magnesium and inorganic phosphorus concentrations in the rumen fluid.
Effectiveness of electrolyte fluids administration was evaluated in treating dehydration, and acid-base balance and electrolyte disturbances in 11 6-19 day-old calves with an experimental osmotic diarrhea induced by magnesium sulfate. All the calves received magnesium sulfate (3.0 g/kg bw as a 15% water solution) by esophageal intubation at 0, 12 and 24 h of the experiment and were monitored for 96 h. The treatment began at the 25 h of the experiment. Six calves initially received 500 ml of Elekroliwet iv. and were then rehydrated orally with Rehydrat applied at 27, 30, 36 and 48 h. No milk was fed during rehydration. In all calves diarrhea occurred within 3-4 h and persisted until 48-72 h of the experiment. An increase in PCV, serum total proteins, inorganic P, urea, contents of Na and Cl and a decrease in blood pH, AB and BE values were found at 24 h. In 5 non-treated calves these changes persisted or were intensified and К concentration increased slightly on the second day. Between 72-96 h these values showed a tendency to return or go back to the initial ones with the exception of Na, which decreased significantly. The applied rehydration therapy had a beneficial effect on correcting the disorders developing in the course of diarrhea. The infusion of Elektroliwet counteracted the intensification of dehydration and acid-base disturbances and the following oral rehydration with Rehydrat restored all the tested parameters to their normal values when compared to the non-treated calves.
