Claude Bernard was also the first scientist to suggest using "blind" experiments to make scientific observations more objective. Later, after investigating an epidemic among silkworms in the silk industry in the south of France, Pasteur determined that parasites were the cause.
He recommended only using silkworm eggs that were healthy and had no parasites. This action resolved the epidemic, and the silk industry recovered. Pasteur was sure that pathogens attack the body from the outside. This was the germ theory of disease. However, many scientists could not believe that microscopic beings could harm and even kill people and other comparatively large species. Pasteur said that many diseases, including tuberculosis TB , cholera, anthrax , and smallpox, happen when germs enter the body from the environment.
He believed that vaccines could prevent such diseases and went on to develop a vaccine for rabies. Florence Nightingale — was a British nurse, statistician, and writer. She did pioneering nursing work while caring for wounded soldiers during the Crimean War. Nightingale was from a well-connected family. At first, they did not approve of her studying nursing. However, her parents eventually agreed that she could take a 3-month nursing course in Germany in By , she was the superintendent of a women's hospital in Harley Street, London.
The Crimean War broke out in Sidney Herbert, the Minister for War, asked Nightingale to lead a team of nurses in the military hospitals in Turkey. She arrived in Scutari, Turkey in with 34 nurses whom she had trained. Nightingale was shocked by what she saw.
Exhausted medical staff members were tending to wounded soldiers in unbearable pain, many of whom were dying unnecessarily, while the officials in charge remained indifferent. A lack of medication and poor hygiene standards led to mass infection. Nightingale and her team worked tirelessly to improve hygiene and provide patient services, including cooking facilities and a laundry. Under her influence, the fatality rate fell by two-thirds. In , Nightingale founded a training school for nurses in London. Nurses who trained there went on to work all over the United Kingdom.
They took with them everything that they had learned about sanitation and hygiene, proper hospital planning, and the best ways to achieve health. Nightingale's work also marked a turning point for women, who took on a more significant role in medical care. Childbed fever was fatal in 25 to 30 percent of sporadic cases and 70 to 80 percent of epidemic cases.
She promoted the education of women in medicine. He demonstrated its effectiveness to the public using 50 sheep. All 25 of the unvaccinated sheep died, but only one vaccinated sheep perished, probably from an unrelated cause. He later received the first Nobel Prize in Physiology or Medicine. It was a synthetic version of salicin, which they derived from the plant species Filipendula ulmaria meadowsweet. Within 2 years, it became a global commercial success. His lab also discovered arsphenamine Salvarsan , the first effective treatment for syphilis.
These discoveries were the start of chemotherapy. This discovery changed the course of history, saving millions of lives. Kolff, a Dutch doctor, built the world's first dialysis machine. He later pioneered artificial organs. Gilman and Louis S. Goodman discovered the first effective cancer chemotherapy drug, nitrogen mustard, after noticing that soldiers had abnormally low levels of white blood cells following exposure to nitrogen mustard.
With Harold Harrison, he created the first electrolyte-glucose solution for clinical use. Salk was hailed as a "miracle worker," because polio had become a serious public health problem in the U. John Heysham Gibbon, an American surgeon, invented the heart-lung machine. He also performed the first ever open-heart surgery, repairing an atrial septal defect, also known as a hole in the heart. He also developed the first inkjet ECG printer. They tested it successfully on a dog first, and the technique saved a child's life shortly afterward.
Black, a Scottish doctor and pharmacologist, invented the first beta-blocker after investigating how adrenaline affects the functioning of the human heart. The drug, Propranolol, is a treatment for heart disease. Black also developed cimetidine, a treatment for stomach ulcers. Sternbach, a Polish chemist, discovered diazepam Valium.
Throughout his career, Sternbach also discovered chlordiazepoxide Librium , trimethaphan Arfonad , clonazepam Klonopin , flurazepam Dalmane , flunitrazepam Rohypnol , and nitrazepam Mogadon.

John Enders and colleagues developed the first measles vaccine. It became available in Walton Lillehei, an American surgeon, carried out the first successful human pancreas transplant. Lillehei also pioneered open-heart surgery, as well as new equipment, prostheses, and techniques for cardiothoracic surgery. Maurice Hilleman, an American microbiologist and vaccinologist, produced the first mumps vaccine.
Hilleman developed over 40 vaccines , more than anybody else. Cyclosporine also treats psoriasis and other auto-immune conditions, including severe cases of rheumatoid arthritis.

Various herbal remedies, vitamins and other supplements are widely promoted as preparations that may support cognitive health or prevent or delay Alzheimer's.
Clinical trials have produced mixed results with little evidence to support them as effective treatments. Supplements promoted for cognitive health can interact with medications you're taking for Alzheimer's disease or other health conditions. Work closely with your health care team to create a safe treatment plan with any prescriptions, over-the-counter medications or dietary supplements. Healthy lifestyle choices promote good overall health and may play a role in maintaining cognitive health. Regular exercise is an important part of a treatment plan.
Activities such as a daily walk can help improve mood and maintain the health of joints, muscles and the heart. Exercise can also promote restful sleep and prevent constipation. People with Alzheimer's who develop trouble walking may still be able to use a stationary bike or participate in chair exercises. People with Alzheimer's may forget to eat, lose interest in preparing meals or not eat a healthy combination of foods.
They may also forget to drink enough, leading to dehydration and constipation. Social interactions and activities can support the abilities and skills that are preserved.
Doing things that are meaningful and enjoyable are important for the overall well-being of a person with Alzheimer's disease. These might include:.
People with Alzheimer's disease experience a mixture of emotions — confusion, frustration, anger, fear, uncertainty, grief and depression. If you're caring for someone with Alzheimer's, you can help them cope with the disease by being there to listen, reassuring the person that life can still be enjoyed, providing support, and doing your best to help the person retain dignity and self-respect.
A calm and stable home environment can help reduce behavior problems. New situations, noise, large groups of people, being rushed or pressed to remember, or being asked to do complicated tasks can cause anxiety. As a person with Alzheimer's becomes upset, the ability to think clearly declines even more. Caring for a person with Alzheimer's disease is physically and emotionally demanding.
Feelings of anger and guilt, stress and discouragement, worry and grief, and social isolation are common. Caregiving can even take a toll on the caregiver's physical health. Paying attention to your own needs and well-being is one of the most important things you can do for yourself and for the person with Alzheimer's. Many people with Alzheimer's and their families benefit from counseling or local support services.
Contact your local Alzheimer's Association affiliate to connect with support groups, doctors, occupational therapists, resources and referrals, home care agencies, residential care facilities, a telephone help line, and educational seminars. Medical care for the loss of memory or other thinking skills usually requires a team or partner strategy. If you are concerned about your memory loss or related symptoms, ask a close relative or friend to go with you to a doctor's appointment. In addition to providing support, your partner can provide help in answering questions. If you are accompanying someone on a doctor's appointment, your role may be to provide some history or your perspective on changes you have observed.
This teamwork is an important part of medical care for initial appointments and throughout a treatment plan. Your primary care doctor may refer you to a neurologist, psychiatrist, neuropsychologist or other specialist for further evaluation.
You can prepare for your appointment by writing down as much information as possible to share. Information may include:. Your doctor will likely ask a number of the following questions to understand changes in memory or other thinking skills. If you are accompanying someone to an appointment, be prepared to provide your perspective as needed.
