- BACKGROUND: Trauma and major surgery stimulate a cascade of events that mediate the inflammatory response. The aim of our study was to determine whether or not hysterectomy leads to release of cytokines, cortisol, and C-reactive protein (CRP), activation of neutrophils, and activation of the complement cascade. A further aim was to compare laparoscopic and abdominal hysterectomy with regard to the same parameters. STUDY DESIGN: Twenty-four consecutive patients were randomized to either abdominal (n = 12) or laparoscopic hysterectomy (n = 12). Blood samples were drawn preoperatively, intraoperatively, and then at one minute, 24 hours, and seven days postoperatively. Interleukin-6 (IL-6) levels were used to evaluate cytokine release, cortisol and CRP to evaluate the inflammatory response, and polymorphonuclear (PMN) elastase to detect neutrophil activation. To evaluate complement activation, the terminal C5b-9 complement complex (TCC) was determined. RESULTS: Interleukin-6 concentrations were significantly elevated one minute and 24 hours postoperatively in both groups. Independent of the surgical technique or operative time, the highest IL-6 concentration was reached four hours after beginning the operation. Cortisol levels were significantly elevated during and after the operation in both groups. C-reactive peptide levels were significantly elevated in both groups 24 hours and seven days after the operation. Polymorphonuclear elastase was elevated 24 hours postoperatively in both groups. There were no signs of complement activation during the operative period or postoperatively in either patient group. CONCLUSIONS: Our results indicate serious tissue trauma during both laparoscopic and abdominal hysterectomy. The extent of surgical trauma did not differ between the two operative methods.

Potential of a blend of E8,E10-120H and E8,E10-12Ac for mating disruption of codling moth, Cydia pomonella L (Lep, Tortricidae)

Journal article (peer-reviewed)abstract
- Dispensers of E8,E10-12OH (codlemone), E8,E10-12Ac (codlemone acetate), or both dispenser types were placed on the corners of 100 m(2) and 300 m(2) plots within apple orchards. Communication disruption of male codling moths, Cydia pomonella, was monitored with pheromone traps in the centres of these plots. In the 300 m(2) plots, trap catch was reduced only by codlemone. In the 100 m(2) plots, trap catch was reduced in all three treatments, fewest males were caught in plots treated with both codlemone and codlemone acetate. Males were attracted to codlemone dispensers, they were also flying actively around the tree crowns, well above the dispensers. This behaviour was not observed in treatments with codlemone acetate, where male orientation flights were directed only towards the trap in the plot centre. The antagonistic effect of each of the four geometric isomers of codlemone acetate was shown by another trap test. Addition of 20% E,E-; E,Z-; Z,E- or Z8,Z10-12Ac decreased male attraction to traps baited with E8, E10-12OH.
