Isotonic Sodium Chloride

The aim of this study was to develop a diagnostic procedure for pumping unit malfunction by radionuclide imaging (RI) and to validate the method by comparing the results with those obtained using more conventional methods. Fifteen radionuclide investigations were performed in 11 patients with intraperitoneal implantable insulin pumps. One mCi of 99 mTc in 1 ml isotonic sodium chloride was injected into the reservoir. The results based on catheter visualization and peritoneal accumulation were compared blindly to the efficacy of alkaline rinses and laparoscopic findings. In all RI stoppage cases except one alkaline rinses failed to restore flow. Where laparoscopy was performed, comparisons were concordant i.e. no outflow from the tip of the catheter. The RI images obtained were reproduced in vitro using a pump under normal flow conditions and complete proximal and distal catheter obstruction. RI is a safe, quick non invasive method which allows the location of the site of pump/catheter malfunction within a one step procedure and the prediction of the efficacy of sodium hydroxide rinses.

Optimum Recovery

The cross-incompatibility barrier between 4x wheat and rye has limited the genetic base for triticale breeding. Experiments designed to improve the synthesis of wheat-rye amphihaploids were conducted. The effects of 2,4-D on crossability and 3x hybrid embryo differentiation, and the influence of one-step and two-step media on the culture of immature 3x embryos in vitro, were investigated. Application of 10 mg L-1 2,4-D slightly improved seed set but significantly reduced the frequency of normal embryos. In contrast to the reported favourable effect of 2,4-D on haploid embryo formation in wheat × maize crosses, the application of 2,4-D in the present study offers no real advantage on amphihaploid embryo formation from 4x wheat × rye crosses. For small and immature wheat-rye hybrid (3x) embryos, optimum recovery in vitro was obtained via a two-step procedure consisting of a semi-solid MN medium followed by MS medium supplemented with IAA (1 mg L-1) and BAP (1 mg L-1). For bigger and well-differentiated embryos, the use of a one-step Gamborg's B5 medium was sufficient.
