ABSTRACT
Objective: The aim of the present study was to evaluate the perioperative effect of magnesium infusion on blood sugar level in patients with diabetes mellitus undergoing cardiac surgery. Design: This was a double-blind randomized study. Setting: The study was conducted at cardiac center. Patients: The study included 122 adult patients. Intervention: Group M – The patients received a continuous infusion of magnesium sulfate (without a loading dose) at 15 mg/kg/h. The infusion rate was started 20 min before induction maintained during surgery and the first postoperative 24 h. The medication was prepared by adding 5 g magnesium sulfate in 50 ml syringe. Group C – The patients received equal amount of normal saline. Measurements: The monitors included heart rate, mean arterial blood pressure, central venous pressure, urine output, blood levels of magnesium, sugar, and potassium. Results: The blood sugar level and the required insulin significantly decreased with Group M than Group C (P < 0.05). There were minimal changes in the potassium level in Group M, but potassium decreased in patients of Group C (P < 0.05). The amount of urine output was too much higher in Group M than Group C (P < 0.05). The pharmacological and mechanical support significantly decreased with Group M than Group C (P < 0.05). The hospital and Intensive Care Unit length of stay significantly decreased with Group M than Group C (P < 0.05). Conclusion: The magnesium sulfate produced a better-controlled effect on the blood sugar level. It decreased the requirement of insulin infusion and minimized the changes in the blood level of potassium.
ABSTRACT
An experiment was conducted on Agricultural and Biological Research Labs. I.O.N.E.C. from 17/7/2000 till 16/3/2001. Experiment included sowing five sorghum cultivar seeds [i.e Rasoul, Motamyes, SD-10 and SD-9]. Sorghum plants were pulled out with its roots at physiological ripening stage, dried, grilled, and then used with soil at a rate of 3 and 6 g. residues/kg. soil, to study the direct effect on emergence and growth of broad bean. Results indicated that, sorghum residues added to the soil at t rate of 3 or 6 g. emergence of broad bean. On the other hand, the concentration of 6 g/residues/kg. Soil reduced the total plant dry weight compared to the control, but 3 g. residues/kg. Soil induced plant growth, i.e. plant height from 40.4 cm. to 44.4 cm and total plant dry weight from 30.5 g/plant to 36.8 g/plant when compared with 3 g. peatmoss/kg. Soil, respectively. Considerable variations were observed on the allelopathic effect among the tested cultivars against broad bean plant. Rasoul cv. was the most inhibitor cv. [plant height was 40.1 cm. and total plant dry weight was 33.1 g/plant], while Tabit cv. Was the least inhibitor cv. [plant height was 46.7 cm and total plant dry weight was 39.7 g/plant]
