The comparative evaluation of gabapentin and carbamazepine for pain management in Guillain-Barré syndrome patients in the intensive care unit.

We evaluated the effects of gabapentin and carbamazepine for pain relief in 36 Guillain-Barré syndrome patients. Patients were randomly assigned to receive gabapentin 300 mg, carbamazepine 100 mg, or matching placebo 3 times a day for 7 days. Fentanyl 2 microg/kg was used as a supplementary analgesic on patient demand.

Influence of pH on soil charge characteristics and cadmium sorption in some noncontaminated soils of Indian subtropics.

Concentrations of total dissolved cadmium (Cd) and activity of its free ions in soil solution are suggested to be influenced by soil pH, organic matter (OM) content, cation exchange capacity (CEC), and clay mineralogy. We investigated the sorption of Cd by taking 25-, 50-, and 100-microM Cd solutions in five noncontaminated soils of West Bengal, India, having differing chemical properties with batch sorption experiments. The charge characteristics and point of zero salt effect (PZSE) of all experimental soils were calculated by the potentiometric titration method measuring the adsorption of H+ and OH- on amphoteric surfaces in solutions of varying ionic strength (I).

Role of various extractants in removing group-IIB elements of soils incubated with EDTA.

This paper presents the results of an experimental investigation undertaken to evaluate different extractant solutions viz. HCl, Mg(NO3)2, and DTPA with the range of concentration from 0.001 to 0.
