| | Changes in Inhaler Devices for Asthma And COPD |
 | | Optimal therapy for many patients requires control of both pathologic mechanisms through the use of inhaled bronchodilators and corticosteroids. | | | Bronchodilator and corticosteroid inhalers eject a fine mist of medication which works directly on the bronchiole mucosa and smooth muscle when used properly. | | | Bronchospasm, a major component of asthma and COPD, limits airflow and can be relieved by bronchodilator inhaler medication. |

| | Treating Asthma with Aromatic Essential Oils By Lori Torquati |
| | A massage oil to decrease inflammation of the bronchioles, reduce muscle spasms and calm the CNS is to be applied to the entire back and shoulders as well as the upper chest and feet. Great at bedtime too. | | | After the breath of life returns to “normal” often times after a prolonged attack or bronchitis, the back, shoulder and chest muscles are very tight and sore from labored breathing. | | | Inhale deeply and slowly for 2-3 minutes prior to breathing exercises. There is a practice in Yoga known as prana yama, or breath work that stimulates and strengthens the respiratory system. |

| | British Journal of Pharmacology - Abstract of article: Multiple calcium channels regulate neurotransmitter release from ... |
| | Twitch-like contractions and non-adrenergic non-cholinergic (NANC) relaxations evoked by electrical field stimulation (EFS) of the cat bronchiole were used to examine the voltage-activated calcium channels involved in excitatory and inhibitory neurotransmission in the cat bronchiole. | | | Taken together, these results suggest that generation of twitch-like contraction and later slow NANC relaxation are regulated by N-type calcium channels, whereas generation of the initial fast NANC relaxation possibly involves R-type calcium channel. | | | M), the L-type calcium channel antagonist, did not affect the twitch-like contraction and NANC relaxations. |

| | The clinical signs of bronchiolitis associated with SAD are similar to those attributed to inhalation of aeroantigens. | | | Inflammation in the bronchiole leads to contraction of the muscle, which causes narrowing of the airway. | | | In time, inflammation in the bronchiole causes structural changes that are relatively permanent and act to interfere with the ability of drugs to cause the airway to expand. |

| | BRONCHUS & BRONCHIOLE |
| | Below a diameter of about 0.5 mm, the smooth muscle in the wall has sufficient tone to prevent collapse; and a "bronchiole" (the term is a diminutive, indicating a smaller version of the bronchus) is an air passageway whose walls contain only smooth muscle as a reinforcement. | | | The principal structural difference between a "bronchus" and a "bronchiole" is the presence or absence of hyaline cartilage as a reinforcement in the wall. | | | In bronchi, the tube diameter is comparatively large, and to prevent collapse as the lungs expand, it's necessary to add some stiffness; this is the role of the cartilage plates, which decrease in size as the caliber of the bronchi does. |

| | Most often atelectasis is secondary to a mucus plug that occludes a bronchiole segment. | | | Atelectasis is a process whereby a segment of lung is not ventilated and becomes "collapsed." This process can occur for several different reasons including "compression" of a lung segment (like from an effusion pushing on the tissue), obstruction of a bronchiole (tumor, post-operative or mucus plug), and contraction (scarring of lung). | | | Click the CXR below to see an example of plate-like atelectasis. |
