It is more than strange that the Black Book of 194364 cites a CO content of 2 to 3% for Diesel exhaust. It is not likely that this was printed in error, since the allegedly lethal nature of Diesel exhaust is still a vital brick in the foundation of the Holocaust. The value of 2 to 3% CO given for Diesel exhaust cannot be traced back to any witness statements. One may assume that the World Jewish Congress had subject experts at its disposal in this issue as well the accompanying expositions of the biochemical effects of CO on hemoglobin would suggest this. 

With each report of a new biochemical effect of TSH on the thyroid gland, a new assay for TSH has been developed. Many of the assays have withstood the test of time. It is not within the scope of this chapter to discuss all the assays which have been developed over the years. Rather we will discuss recent progress in this field and describe those methods that are particularly useful in clinical situations. Kirkham s review (K3) is helpful on the subject of TSH assays. 

In the last few years papers reporting on the physiological and biochemical effects of SO2 have appeared. A subject which has till recently been the preserve mainly of the field botanist and ecologist is now moving into the laboratory. 

How relevant are these phenomena First, many oscillating reactions exist and play an important role in living matter. Biochemical oscillations and also the inorganic oscillatory Belousov-Zhabotinsky system are very complex reaction networks. Oscillating surface reactions though are much simpler and so offer convenient model systems to investigate the realm of non-equilibrium reactions on a fundamental level. Secondly, as mentioned above, the conditions under which nonlinear effects such as those caused by autocatalytic steps lead to uncontrollable situations, which should be avoided in practice. Hence, some knowledge about the subject is desired. Finally, the application of forced oscillations in some reactions may lead to better performance in favorable situations for example, when a catalytic system alternates between conditions where the catalyst deactivates due to carbon deposition and conditions where this deposit is reacted away. 

O Pain is an unpleasant subjective experience that is the net effect of a complex interaction of the ascending and descending nervous systems involving biochemical, physiologic, psychological, and neocortical processes. 

Interest in nitroso compounds as intermediates for organic synthesis has faded due mainly to their potential toxic effects. Table 6, shows that activity in this field is centered mainly on occupational and environmental pollution subjects. An ample review appeared recently on V-nitroso compounds, including chemical, biochemical and analytical aspects566.
