Brief Summary:
This study is designed to collect lung washing samples and small pieces of tissue (biopsies) from the lungs of people who do not have any allergies or asthma. These samples will be used by researchers in the future as control samples to compare to samples from people with chronic lung diseases such as allergic asthma or emphysema. Control samples are samples are very important in laboratory experiments so that the researchers can tell what may be labeled as different or abnormal in samples from people with lung disease.

Condition or disease

Detailed Description:

Participants in this study must be between the ages of 18 and 45 years and have no general health concerns and do not have allergies or asthma. If qualified, participants will come to the study site up to 3 times over about a 3-week period. This study involves answering questions about your medical history, having a physical exam, urine pregnancy tests for females who might be able to have children, and breathing tests. You will also have a blood draw to test for bleeding problems and an allergy skin test to see if you are allergic to common things. If it is safe for you, you will have a bronchoscopy. A bronchoscopy is a medical procedure to get samples of cells and small pieces of tissue (biopsies) from your lungs.

The study has some risks. The breathing tests may cause you to feel short of breath or dizzy. The allergy skin test will itch and cause a reaction like a mosquito bite.

There are some risks involved with the bronchoscopy. Most people get a sore throat and feel tired after the procedure. You may need to feel a little short of breath. There is a very rare risk of serious problems.

Women are able to join this study only if they are not pregnant or breast-feeding. If you have plans to become pregnant during the time period in which the study takes place, you should not join this study. For women, a urine pregnancy test will be done at the first visit and you will be asked to be on birth control. The study staff can talk to you about the type of birth control that is all right to use in this study.
