| • | Is Albumin Administration in Hypoalbuminemic Elderly Cardiac Surgery Patients of Benefit with Regard to Inflammation, Endothelial Activation, and Long-Term Kidney Function? |
|
BACKGROUND: Because patients with low albumin levels may benefit from human albumin (HA) administration, we studied correction of hypovolemia with HA in hypoalbuminic elderly cardiac surgery patients. METHODS: In a prospective, randomized study, 50 patients aged >80 yr undergoing cardiac surgery using cardiopulmonary bypass with a preoperative serum albumin concentration of <3.5 mg/dL, received either 5% HA (n = 25) or hydroxyethyl starch (6% HES 130/0.4) (n = 25). Volume was added to the priming (500 mL) and given until the morning of the second postoperative day to keep pulmonary capillary wedge pressure or central venous pressure between 12 and 14 mm Hg. RESULTS: Inflammatory response (interleukins-6, -10), endothelial activation (intercellular adhesion molecule-1), and kidney function (including glutathione transferase- and neutrophil gelatinase-associated lipocalin) were measured after induction of anesthesia, 5 h after surgery, and the first and second postoperative day. A follow-up, approximately 60 days after discharge from the hospital, was done. Two thousand nine hundred eighty ± 430 mL of HA and 3060 ± 680 mL of HES 130/0.4 were given. Serum albumin concentration was significantly increased by HA (to 4.5 ± 0.3 mg/dL). Serum creatinine, glomerular filtration rate, and urinary levels of -glutathione transferase and neutrophil gelatinase-associated lipocalin were not different in the HA-compared to the HES-treated patients. The inflammatory response was similar in both groups, whereas endothelial activation was less in the HES group. None of the patients developed renal failure requiring renal replacement therapy. CONCLUSION: Use of HA in hypoalbuminemic cardiac surgery patients aged >80 yr was without benefit with regard to inflammatory response, endothelial activation, and renal function compared to 6% HES 130/0.4. |

| • | Impact of Sugar Beet Cyst Nematode, Heterodera schachtii, on Some Physiological Aspects of Two Sugar Beet Cultivars, Nemakill and 7233, in the Rhizosphere Condition |
| The impact of beet cyst nematodes, Heterodera schachtii, on some physiological aspects including proline, potassium and sodium in two sugar beet cultivars, a susceptible 7233 and a resistance Nemakill was evaluated in the rhizosphere condition. In this study a bioassay was conducted with sugar beet seedlings in the presence of different populations of the beet cyst nematodes, 0, 10, 20 juveniles 1-1 g. soil as a biostressor in glass tubes (20x3 cm Ø) in growth chamber, totally 36 tubes. The tubes were placed in a growth chamber with 16-h artificial light, eight fluorescent 40 watts, at 25 and 21°C at darkness and moistened regularly with a half Hoagland`s nutrient solution. The proline, potassium and sodium changes of treated and untreated plants were measured 45 days after nematodes` inoculation. In this stage, the root of plant was freed from soil and debrises by a fine jet of water stream and the number of developed females of nematodes counted on the root surface and recorded. Results of this study revealed that the proline in leaves, sodium in leaves and roots as well as potassium in roots were increased but K+ decreased in leaves in both cultivars as the population of nematodes increased in the soil. Results of this study indicated that a few number of nematodes` females was developed on Nemakill`s roots in comparison with the other treated and untreated susceptible cultivar in the rhizosphere condition. | |
