Interstitial lung disease Interstitial lung disease Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of lung diseases affecting the interstitium (the tissue and space around the air sacs of the lungs). It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, perivascular and perilymphatic tissues. It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage. But in interstitial lung disease, the repair process goes awry and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it more difficult
Citrus leprosis disease In fruits, dark and depressed lesions are found in large numbers and affecting only the external part. Commercial losses result from undesirable appearance and fruits falling. Some differences in symptoms produced by CiLV-C and CiLV-N have been reported; in leaves and fruits, lesions caused by the nuclear type are smaller and more numerous than those caused by the cytoplasmic type. Lesions caused by CiLV-C shows additional halos, making them look larger. This disease is considered an important problem in citriculture in countries where it has been established, and is considered the major viral disease in citrus in Brazil. Damage by
