Article Details
While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

The sensitivity of Na+, K+ ATPase as an indicator of blood diseases
Abstract
Background: Blood-related hereditary diseases are widespread in Eastern and SouthWestern regions of Saudi Arabia until recently. In this study, we used Na+, K+ATPase as an enzymatic indicator for the diagnosis of the diseases.
Materials and methods: Individuals with different blood diseases (iron deficiency (n=13), anemia (n=14), thalassemia (n=16) and sickle cell anemia (n=12) were studied for Na+, K+-ATPase activity in the plasma membrane of red blood cell and compared with those of the healthy ones (n=20) of the same age and gender living in Jeddah, Saudi Arabia.
Results: There was a significant elevation in the specific activity of Na+, K+ATPase in individuals with anemia compared with those of control (0.0094 + 0.001 nmol / mg protein/min versus 0.0061 0.001). On the other hand, there was a significant reduction in enzyme activity in thalassemia (0.0028 0.002 nmol / mg protein/min) and sickle cell anemia cases (0.0042 0.001 nmol / mg protein/min) compared to the control group. The cut off value for Na+, K+ATPase activity is 0.005 μmol Pi/minshowing 94% sensitivity and 93% specificity for the differentiation of blood abnormality.
Conclusion: It can be recommended that the activity of Na+, K+-ATPase can be used for the diagnosis of individuals with blood diseases/disorders.
