Na+/K+-ATPase is a prevalent enzyme that maintains the Na+ and K+ gradients across the cell membrane by transporting three Na+ out and two K+ into the cell, the aim of this study is to provide detailed mechanistic insights, potentially with important effects on physiological regulation of active Na and K transport in tissues of Aerobic Thyroid Patient. Thyroid tissues were obtained from a 35 year old patients, the operation was carried out at the Al-Hadi Specialist Hospital in Samarra city, the sample was stored at -20ºC until used. The purification protocol included Salt Precipitation, Ion Exchange Chromatography, Gel Filtration and Electrophoresis, a spectrophotometric method was used to determine the enzyme activity. kinetic parameters was also obtained for the enzyme. Partial purification of Na+/K+-ATPase revealed two isoenzymes (I ,II). The purity of separated isoenzymes were proved by SDS-PAGE electrophoresis. The kinetic characteristics of Na+/K+-ATPase showed that optimum substrate concentration about 1.5mM, Km 1.052mM, and Vmax 6.062, optimum temperature was 37 ºC, optimum pH 7.4 and optimum time in 25 min. Na+/K+-ATPase purified from Thyroid tissue has distinct kinetic characteristic that reflects the importance of intracellular regulation of specific Na+/K+-ATPase pump which gives cells the ability to precisely coordinate to their physiological requirements .
Abstract
This study dealt with " The Strategic analysis of Operating Income". The study Concerned with two main variables, they are: Strategic analysis and operating income and used one of the total strategic analysis tools, it is "resources analysis method" through analysing the change in operating income in the years that taken in comparing in three components: growth, price recovery and productivity.
To achieve the goal of the research, the study depended upon a hypothesis, "The strategic analysis of operating income leads to supply the appropriate information for the management to make sure of executing its definite strategies".

The research focused on the issue of the crisis of the Asian Tigers and the mortgage crisis and comparing them in terms of causes and repercussions. It may meet most of the financial crises in many of its causes, factors, roots and results in the advanced and the developing countries. This crisis has its own pattern and its causes and nature and it is characterized by a crisis of cash liquidity and the collapse of many banks and declare bankruptcy and a sharp decline in stock prices and indices of the stock market and so far the common denominators among the causes but does not mean this There are differences between the financial c
