Abstract

N,N’-disalicylidene-1,2-diaminopropane is a copper inhibitor present in some adhesive plasters, rubber products and gasoline. Upon contact with water it is hydrolyzed to salicylaldehyde and 1,2-diaminopropane. All patients in this study showed positive patch-test reactions to N,N’-disalicylidene-1,2-diaminopropane, and also to 1,2-diaminopropane and ethylenediamine. None reacted to salicylaldehyde. Patch testing with different N,N’-disalicylidene-derivatives showed localization of the amino groups in positions 1 and 2 to be a prerequisite of cross-reactivity to 1,2-diaminopropane and ethylenediamine. An extraction procedure and a high-performance liquid chromatography (HPLC) method for the analysis of adhesive plasters is described. Studies of the hydrolysis of the copper inhibitor at physiological pH showed rapid formation of 1,2-diaminopropane under biomimetic conditions.

Abstract

Background and Aims:
Postoperative pain results in prolonged hospital stay and delayed return to normal activity. This study was conducted with the aim of evaluating the analgesic efficacy of gelfoam soaked in levobupivacaine with or without dexamethasone placed in the epidural space in patients undergoing lumbar laminectomy.

Methods:
Ninety adult patients were randomised into three groups. Gelfoam was soaked in 12 mL of 0.9% sodium chloride in Group P, 10 mL of 0.25% levobupivacaine + 2 mL of 0.9% sodium chloride in Group L, and 10 mL of 0.25% levobupivacaine + 2 mL of dexamethasone in group LD. The primary outcome was time to first request for rescue analgesia. Total 24-h tramadol consumption, and postoperative visual analog scale (VAS) scores were recorded. Chi-square test and analysis of variance test were used, and P < 0.05 was considered significant. Results: 75 patients completed the study. Time to first rescue analgesia was longer in group LD [10.11 ± 3.10 h] compared with group L [6.48 ± 2.36 h] and group P [1.76 ± 1.13 h]. Total 24-h tramadol consumption was lower in group LD (88 ± 66.58 mg) and group L (120 ± 70.7 mg) compared with group P (280 ± 64.5 mg). Postoperative VAS scores were lower in group LD and group L compared with group P, both at rest and on movement. Conclusion: Epidural gelfoam soaked in levobupivacaine and dexamethasone prolongs the duration of analgesia and decreases rescue analgesic consumption and VAS score postoperatively, in patients undergoing lumbar laminectomy.

Abstract

Two new penta­borates, tris­odium zinc cadmium penta­borate, Na3Zn0.912Cd0.088B5O10, and tris­odium zinc magnesium penta­borate, Na3Zn0.845Mg0.155B5O10, have been synthesized by high-temperature solution reactions at 1023 K. Their crystal structures were determined by single-crystal X-ray diffraction. Both solid solutions crystallize in the ortho­rhom­bic form of the parent compound Na3ZnB5O10 (space group type Pbca, Z = 8) and contain the double ring [B5O10]5− anion composed of one BO4 tetra­hedron and four BO3 triangles as the basic structural motif. The anions are bridged by tetra­hedrally coordinated and occupationally disordered M 2+ (M = Zn/Cd, Zn/Mg) cations via common O atoms to form [MB5O10]n 3n− layers. The intra­layer inter­secting channels and the inter­layer voids are occupied by Na+ cations to balance the charge.
