HOW TO DETERMINE PCV (PACKED CELL VOLUME)

The Packed Cell Volume (PCV) Test 1. Objective: This is one of the oldest tests done in medical practice. The objective of this test was to determine the percentage of red blood cells (RBCs) in whole blood. It  also helped to assess the blood’s capacity to carry oxygen. ________________________________________ 2. Principle: The test was based on the principle that when blood was centrifuged, the red blood cells settled at the bottom of the tube, forming a packed column. The ratio of the packed RBC column to the total blood column gave the packed cell volume (PCV), expressed as a percentage. ________________________________________ 3. Materials: • Microhematocrit capillary tubes • Microhematocrit centrifuge • Plasticine or sealing clay • Microhematocrit reader • Lancet • Alcohol swab • Cotton ________________________________________ 4. Procedure (Microhematocrit Method): 1. The fingertip was cleaned with an alcohol swab and pricked with a sterile lancet. 2. Blood was collected into ...

LUPUS:AN AUTO- IMMUNE DISEASE

 Autoimmune diseases are those in which the body , for unknown reasons begin to fight itself and lead to major health consequences such as muscular and CNS degeneration, internal bleeding, severe damage to body tissue, abnormal growth that affects organs, and changes in the way body organs function e.t.c.

Coined from the words "Auto" and "immune" it stresses that the condition generates internally–for unknown reasons–abd harms it's own system. Think about a snake swallowing its own self from the tail end!

Some common autoimmune diseases include; Hashimoto's autoimmune thyroiditis,Celiac disease,Type 1 diabetes mellitus,Graves' disease,Inflammatory bowel disease (IBD).


SYSTEMIC LUPUS ERYTHEMATOUS

 Systemic lupus erythematous is one of such auto immune diseases. It is a group of autoimmune disease with an unknown cause. It affects many organs, especially skin, joints and kidneys.



Lupus results in the immune system attacking the body's cells and tissues, causing tissue inflammation and damage.


Lupus has different manifestations and can present in a variety of ways. In Nigeria, the commonest symptoms are recurrent fever, joint pains, skin rashes, fatigue, mouth sores, loss of hair, anaemia and epileptic seizures.



You are most likely to develop Lupus if you're of African descent, Hispanic, Caucasian or a native American. Women are about nine times more likely to develop the condition. Also relatives of people with lupus have a greater chance of developing lupus. 


Visit a PHYSICIAN to get tested when you have symptoms that mimic those of malaria.


Do not abuse drugs or self-medicate as you may be treating the wrong disease!

China, the United States, and the European Union are the world's largest pork producers, accounting for roughly 80% of total pork production. A study published in the Proceedings of the National Academy of Sciences found that pork had significantly higher levels of antibiotics than chicken, beef, and lamb. https://bringsconserve.com/qp970858?key=0b6d33fbbd24ee17ba922b2bfaf034ef  Antibiotics are used in the breeding process primarily because they reduce disease and mortality in pigs while also rapidly increasing pig weight. In the United States, roughly 27.1 percent of Medically important antibiotics are used in the pig industry, and...
