“…These values were low compared to the range of 0.19 to 0.24 mmol L − 1 bovine plasma from Hornick et al (1998), 0.097 to 0.17 mmol L − 1 in Istasse et al (1990), 0.11 to 0.12 mmol L − 1 of Lister et al (1973) and 0.14 to 0.22 mmol L − 1 of Colditz and Kellaway (1972). The difference observed between the present and published studies may be due to the method used to estimate plasma creatinine, as these studies used the Jaffé alkaline-picrate method to estimate creatinine, a method that is known to over-estimate creatinine concentration because of cross-reactivity with blood proteins and glucose (Edwards and Whyte, 1958).…”

“…Likewise, stress induced by exposure to low temperatures led to increased haematocrit values in pregnant cows (Lister et al, 1973), in sheep (Bailey, 1964) and in poultry (Kubena, May, Reece & Deaton, 1972).…”

SUMMARYWhen used to restrain rats while obtaining cardiac blood, there was little difference between the effects of ether, pentobarbitone sodium, and fentanyl plus droperidol on acid-base balance, haemoglobin, haematocrit, plasma protein, calcium and magnesium. The use of manual restraint increased blood acidity, plasma protein, calcium and magnesium, but decreased blood glucose. Haemoglobin and haematocrit values were higher for tail blood than for blood removed from the heart or abdominal aorta. 85The removal of blood from the rat usually involves a certain degree of stress to the animal.During work on iron metabolism in progress in this laboratory a number of blood sampling methods were used, with varying degrees of response from the rat. Thus it was decided to compare the effects of these methods of blood sampling on some widely used biochemical and haematological parameters. The effects of restraining rats using a gaseous anaesthetic (ether), an intraperitoneal anaesthetic (pentobarbitone sodium), and a neuroleptanalgesic agent (a combination of fentanyl and droperidol), were compared with manual restraint.In another experiment the influence of the site of blood removal on some acid-base and haematological values was examined. MATERIALS AND METHODSFemale albino Wi star rats of about 300 g bodyweight were used in this study and were maintained on a balanced pelleted diet prior to the experiments. Effects of restraintThe following methods of restraint were employed while cardiac punctures were carried out to remove blood. ·Present address:
