A similar series of events (excluding increased blood flow) are associated with the growth and differentiation which follows fertilization of the ovum it would appear that the nucleoprotein of the sperm may be considered as the primordial growth and differentiation regulating agent basically related to hormone action. 

As illustrated in Table 43-5, the discovery of the nuclear receptor superfamily has led to an important understanding of how a variety of metabolites and xenobi-otics regulate gene expression and thus the metabolism, detoxification, and elimination of normal body products and exogenous agents such as pharmaceuticals. Not surprisingly, this area is a fertile field for investigation of new therapeutic interventions. 

During this year some Important reviews related to regulation of fertility were published. These dealt with the following subjects physiology of early pregnancy,aspects of fertility control, antifertility agents, 7,198 antifertility agents in the future,treatment of infer-... 

Nitrate (NO.D in natural waters is derived from sources such as fertilizers and undertreated animal and human waste. U.S. environmental regulations set a maximum of 10 ppm NO3 nitrogen in drinking water. Nitrate is commonly analyzed by reduction to nitrite (NO2), followed by a colorimetric assay of NO2. Metallic Cd has been the most common reducing agent for NO3. However, the use of toxic Cd should be curtailed to protect the environment.
