Figure 2 : (a) A photomicrograph of a section in the nasal mucosa of the control group showing normal
nasal cavity mucosa with respiratory epithelium (E) rests on thin basal lamina (arrow) and lamina propria
of loose connective tissue containing multiple blood vessels (BV). (b) A photomicrograph of a section in
the nasal polyp of group IIb showing damage of respiratory epithelium (E) rests on apparently thick
basal lamina (arrow) and lamina propria with numerous cells infiltration (arrow head) and few blood
vessels (BV). (c) A photomicrograph of a section in the nasal polyp of group IIa showing partial damage
of respiratory epithelium (E) rests on apparently thick basal lamina (arrow) and lamina propria with
numerous cells infiltration (arrow head) and few blood vessels (BV). (d) A photomicrograph of a section
in the nasal polyp of group IIIb damage of respiratory epithelium (E) rests on apparently thick basal
lamina (arrow) and lamina propria with numerous cells infiltration (arrow head) and few blood vessels
(BV). (e) A photomicrograph of a section in the nasal polyp of group IIIa showing near normal nasal
mucosa with overcrowded respiratory epithelium (E) rests on apparently thin basal lamina (arrow)
and lamina propria of loose connective tissue containing few cells infiltrations (arrow head) and
many blood vessels (BV) [H&E X400].
