Who invented insulin for the first time?
Insulin was co-discovered by Frederick Banting and Charles Best in 1921. They developed the process to extract and isolate insulin from the pancreas, revolutionizing the treatment of diabetes. Their work led to the mass production of insulin, saving countless lives.
Who is insulin founder?
Dr. Fredrick Banting, Charles Best (a medical student at the time of the discovery), Professor J. J. R. Macleod and Dr. James Collip.
Banting and best?
Banting was an out-of-work doctor/surgeon and Best a medical student in Toronto. The problem with isolating insulin (which controls the blood sugar level) was that the pancreas contained enzymes that destroyed the insulin if it was cut out. Banting had the idea of ligaturing the pancreas in situ so that it withered away leaving the insulin largely unaffected. He employed Best (a doctor's son) to help with the surgery and look after the dogs on which it was done with the permission of the University Professor in charge of the department. I think he was called McLeod (anyway he was a Scot). The experiments were carried out during the summer vacation under hot inclement conditions in a garret room, but they worked. The Nobel prize was given to Banting and McLeod (just because he was head of department and although he was not involved in the research in any way) but not to Best who did all the nasty work. It was said that, as a mere student, he was too young to receive an award. However, he did ultimately become head of department. I was in Toronto fairly soon after his death and was shown his office by his secretary who said that he was a really nice man. So he did win after all. I should mention that there had been numerous attempts to isolate insulin by the more traditional biochemical methods of isolation and extraction of the pancreas but all had failed. So it was a signal achievement as well as one that was put to practical use in saving lives in the shortest possible time. It would not happen today!!

How old was Frederick Banting at death?
Frederick Banting died on February 21, 1941. He was a fighter plane pilot and his plane got shot down in Newfoundland.
Who found the treatment for diabetes?
The function of the pancreas was discovered as early as 1869 by Paul Langerhans, a German student of medicine. Georg Ludwig Zuelzer was the first person that actually treated dogs with an impure form of insulin. He was not the first to discover the function of pancreas but he is considered the first to actually move on and actually try it out on dogs. This happened in 1906. He did however not finish his work. The first actual injection of insulin happened 11 January 1922. It was not pure enough and the boy who got it had strong allergic reactions. 12 days went past with work and then the boy received another injection, and this time it was successful. Macleod and Banting was awarded the Nobel-price i physiology and medicine in 1923. They managed to produce Insulin of sufficient purity and quantity the year before, and production took place.
What is the peak time when administering regular insulin and NPH insulin?
the peak time for Regular insulin is 4 hours and the peak time for NPH is 8 hours. I take both of them.
What happens in there is over secretion of insulin?
If there is overproduction of insulin then your sugar is low all the time. You will be hypoglycemic all the time.
What will happen if you draw cloudy insulin up first then clear insulin and give to a patient?
The "cloudy" insulins are long-acting, while the "clear" insulins are rapid or short-acting. Drawing up the clear insulins first prevents the vial of short-acting insulin from being contaminated with a long-acting insulin.
Why is cow insulin a good substitue for human insulin?
Insulin from pigs or cows can cause immune reactions in some people, or people may develop an allergy to the insulin over time and it will be ineffective. Human insulin is not immunogenic and so is preferred.
When is the best time to take lantus insulin?
Lantus insulin is best taken once daily at the same time each day to maintain consistent blood sugar levels. It can be administered in the morning or at night, depending on individual preferences and healthcare provider recommendations. It's important to choose a time that fits your routine and ensures you remember to take it consistently. Always consult your healthcare professional for personalized advice.
Does insulin affect your reaction time?
Yes!
