عطلة قبل العطلة للتجهز للعطلة،
و عطلة بعد العطلة لاخذ راحة من العطلة
فلنبدا باولي حلقات مسلسنا الجديد معلومة قصيرة…short notes..وذلك حتي ننعش ذاكرتنا بعد حالة الركود والخمول …ولنبدأ باولي الحلقات ونبذه مختصره عن الهيموجلوبين..ونقول ونتكلم…بطريقه جديد انجليش حبيتين
ولكن بطريقه منتظمه لكي لا نشعر بالملل…
* Hemoglobin is the oxygen-carrying pigment that gives blood its red color and also the predominant protein in red blood cells.
About 90% of hemoglobin is hemoglobin A. (The “A” stands for adult type.)
Although one chemical component accounts for 92% of hemoglobin A, approximately 8% of hemoglobin A is made up of minor components that are chemically slightly different.
These minor components include hemoglobin A1c, A1b, A1a1, and A1a2.
Hemoglobin A1c (HbA1c) is a minor component of hemoglobin to which glucose is bound.
HbA1c also is referred to as glycosylated or glucosylated hemoglobin.
* HbA1c levels depend on the blood glucose concentration.
That is, the higher the glucose concentration in blood, the higher the level of HbA1c. Levels of HbA1c are not influenced by daily fluctuations in the blood glucose concentration but reflect the average glucose levels over the prior six to eight weeks.
Therefore, HbA1c is a useful indicator of how well the blood glucose level has been controlled in the recent past and may be used to monitor the effects of diet, exercise, and drug therapy on blood glucose in diabetic patients.
In healthy, non-diabetic patients the HbA1c level is less than 7% of total hemoglobin.
It has been demonstrated that the complications of diabetes can be delayed or prevented if the HbA1c level can be kept close to 7%. In general, values should be kept below 8%.
* A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot.
Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen.
Blockage of a coronary artery deprives the heart muscle of blood and oxygen,causing injury to the heart muscle.
Injury to the heart muscle causes chest pain and chest pressure sensation.
If blood flow is not restored to the heart muscle within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur.
Muscle continues to die for six to eight hours at which time the heart attack usually is “complete.”
The dead heart muscle is eventually replaced by scar tissue.
وبكده نكون انتهينا من حلقتنا…والي اللقاء بمعلومة جديدة…وشكرا جزيلا…كان معكم عبدالله نجيب
