Toxicology and Safety

Health nd Safety Factors. The toxicological and safety properties of xanthan gum have been extensively investigated (82). On the basis of these studies, the EDA issued a food additive order in 1969 that allowed the use of xanthan gum in food products without specific quantity limitations.

Most of the assessment of toxicology and safety of therapeutics is focused on the patients who are to benefit from the new medicine. However, there are two other groups of individuals (each of which has different exposure profiles) that one must be concerned about the healthcare providers (nurses, pharmacists and physicians) who provide and/or administer the drugs and the individuals involved in manufacturing them. The concerns here are in the realm of occupational toxicology.

The C.I. Constitution number is given in this paper as a guide to references for synthesis in the Colour Index. Any duplication of these syntheses should be attempted only under the supervision of an experienced chemist who is aware of the latest ecological, toxicological, and safety requirements. These requirements must be constantly observed even if attention is not explicidy drawn to them. A further point to note is that dye chemists often write the free sulfonic acid form, even if they have obtained a salt. The reason is that the dyes are often not completely neutral or may not be a defined salt. This commonly arises when potassium or sodium salts are involved, and therefore the free sulfonic acid formula is frequentiy used as a general term. A sulfonate salt does not influence the color as such, but water solubility is affected. Consequently, for pigments the cation is always given in the chemical formula. 

For some typical dyes the C.I. constitution number is given in this book. Any duplication of dyes or application process should be attempted only under the supervision of an experienced chemist who is aware of the latest ecological, toxicological, and safety requirement. This guidance must be constantly observed even if attention is not explicitly drawn to it. 

Dr. Bidlack has been a professional member of the Institute of Food Technologists for more than 30 years. He has served as a member of the annual program committee, as a member of both the Expert Panel on Nutrition and Food Safety and the Scientific Lectureship Committee, and as a scientific lecturer. He was program chairman and chairman of the IFT Toxicology and Safety Evaluation Division (1989-1990) and has served as a member of the Executive Committee for both the TaSE Division and the Nutrition Division. He has served as editor of the TaSE newsletter. For the Southern... 

The edition of this book covering preclinical drug safety (toxicology and safety pharmacology) and pre-clinical and clinical DMPK aspects is considered as a contribution to this principle. 

FCC specifications will respond to advances in knowledge about new manufacturing methods, analytical techniques, or toxicology and safety issues. 

The committee regards as one of its goals the assurance of the safety of properly used food chemicals. This means that FCC specifications will respond to advances in knowledge about new manufacturing methods, analytical techniques, or toxicology and safety issues. 

Two general approaches of gene expression related to toxicology and safety assessment have evolved, either of which can be deployed depending on the nature of the investigation being carried out.

The skin is the primary organ of contact between the organism and its environment. There is extensive commercial interest in dermal toxicology and safety screening because of the many different products used topically for therapeutic and cosmetic purposes. Similar comments can be made about ocular products. 

A-acetylated chitosan is another example of a functional-group-modification-derived chitosan-based pDNA carrier. Kai and Ochiya (2004) have previously reported its potential application in oral gene delivery. In their study, mice were fed with A-acetylated polyplexes carrying pDNA encoding lacZ and interluekin-10. The result of lacZ staining performed 5 days after transfection showed that transgene expression in duodenum, jejunum, ileum, and colon could only be mediated by A-acetylated chitosan but not standard chitosan. However, no evaluation on the toxicity of this chitosan derivative has yet been published. In order to further verify its workability in clinical use, studies on its toxicology and safety are in dire need.
