[The quality control of a photoprotector bag against ultraviolet light].

The action of light on parenteral nutritional solutions may affect the stability of many of their ingredients. The aim of this study is to perform quality controls on a commercial photoprotective bag by quantifying the degradation of riboflavin in isotonic saline solution during forty-eight hours. Thirty solutions were prepared using 5 mg of riboflavin in 500 ml of saline solution.

[An evaluation of the effect of light on a commercial solution of amino acids for parenteral nutrition].

There are few studies on the stability of amino acids in solutions prior to mixing for parenteral nutrition, and even few studies which evaluate the contribution of light to their deterioration. The present study was carried out with the aim of becoming familiar with this parameter of stability in the working conditions of our Pharmacy Service. Two batches of Aminoplasmal L-10 were taken, one of which was subjected to direct low intensity sunlight and the other was maintained in the dark, as a control batch, for between 3-6 months.

[Microbial growth in parenteral nutrition. II. Effects of osmolality].

Study on the behaviour of five microorganisms in different formulations of Parenteral Nutrition (PN) different from each other with regard to osmolarity. The organisms investigated were Staphylococcus aureus (ATCC (12600), Bacillus subtilis (ATCC 6051), Pseudomonas aeruginosa (ATCC 9027), Enterobacter cloacae (ATCC 13047) y Candida albicans (LSH 3156 D). It was observed no direct relation between microbial growth and osmolarity in PN.
