Stress and foods are the main triggers for people with irritable bowel syndrome, or IBS, which can experience a bloated belly, flatulence, abdominal pain and cramps, constipation, diarrhea or alternating constipation and diarrhea. The trigger foods with IBS can vary from one person to another.
The first blood transfusion from animal to human was administered by Dr. Jean-Baptiste Denys, eminent physician to King Louis XIV of France, on June 15, 1667.ransfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors, and platelets.
Experiments with blood transfusions, the transfer of blood or blood components into a person's blood stream, have been carried out for hundreds of years. Many patients have died and it was not until 1901, when the Austrian Karl Landsteiner discovered human blood groups, that blood transfusions became safer.
