Quantitative features of goblet cells in the rat tracheobronchial tree.

The whole-mount quantitative method was used to study the density and distribution of goblet cells in the male rat lung. The airway of the left lung in 10 lung specimens were dissected downwards in the axial pathway and the airway generation levels were determined by an exact numbering system. The entire bronchial mucous membrane was separated and stained according to the PAS-alcian blue whole-mount method.

Upper respiratory tract secretions: pathophysiology.

Nasal fluid is a heterogeneous substance. It consists largely of a secretory product derived from the 100,000 small seromucous glands. The anterior part of the nose has a relatively high secretory capacity, but this does not seem to be caused by secretion from the 200 anterior serous glands.

Quantitative study of goblet cells in the upper lobe of the normal human lung.

Goblet-cell density and distribution were studied in ten specimens of the human adult lung. The bronchial tree of the left upper lobe was dissected, and the bronchial mucosa separated and stained by the whole-mount periodic acid-Schiffalcian blue method. There was a significant fall in the goblet-cell density from the proximal to the distal airways.

Goblet-cell density in the human lung--whole-mount study of the normal left lower lobe.

The whole-mount quantitative method was used to study goblet-cell density and distribution in the adult human lung. The airways of the lower lobe in 10 lung specimens were dissected downwards in the axial pathway and airway generation levels were determined by an exact numbering system. The entire bronchial mucous membrane was separated from the underlying structures and stained with the PAS-alcian blue whole-mount method.
