An attempt has been made to determine the intensity of the biological processes in the soil during the most important periods of the Egyptian farm rotation. The fluctuations of the nitrate content in the surface soil have been taken as the most important index of this activity.In all cases the moisture content of the soil limited these processes more than any other factor.There was observed throughout the season in a cotton field a relatively large amount of nitrate, more than sufficient for the immediate needs of the cotton plant. The lack of response on the part of the Egyptian cotton crop to nitrogenous fertilisers may be accounted for in part, if not entirely, by the fact that nitrification in the soil is well ahead of the needs of the crop.Nitrification under wheat and maize shows in general the same characteristics in Egypt as in other parts of the world; there is no accumulation of nitrate in the soil.The winter fallow, depending for its water on the rainfall, may be a period of steady nitrification when the amount of the rainfall is sufficiently high.

The attentiou of all scientists in Egypt has been more and more closely directed to the problems of Soil-water since about the year 1907. In the first instance this attention was of necessity devoted to the water-logged layer of the soil and sub-soil, to the fluctuations of this layer in time and in space, and to its effects on the cotton plant.

Ionizing radiation considered as an immunosuppressive factor upon over dose of exposure. Radiation field workers usually following a periodic checkup to monitor changes in their clinical status. Cell Mediated Immunity (CMI) has an important cytokines that regulate this specific immunological process. This study estimated the Interleukins (IL-2, IL-12 and IL-18) levels in serum samples using ELISA technique. Serum samples were collected from X-ray Technicians (Radiography, Fluoroscopy and Computed Tomography Scan Technicians) working in AL-Muthanna governorate hospitals. A total of (60) technicians and (30) control were involved in this research. Results showed significant decrease in IL-2 levels and increase in IL-18 levels in test groups (technicians) as compared with controls. While, IL-12 levels did not show a difference; all obtained values were within normal range. Overdose of X-ray exposure caused CMI suppression via disturbing the levels of critical cytokines (IL-2 and IL-18) leading to CMI loss regulation.
