ABSTRACT
The prevalence of cysticercosis in hog muscles was correlated with oculo-orbital prevalence, and histologic characteristics of changes in the parasite and hog were observed. The orbital contents, globe, and eyelids of 39 hogs affected with Cysticercus cellulosae were examined. Thirty-seven parasites were found: 35 within the orbit and two intraocular. Twenty parasites with adjacent host tissue were studied histologically. Inflammatory infiltrates ranging from diffuse lymphoplasmacytic to dense granulomas were seen in 16 cysticerci. The scolex was unaltered in all specimens.

Due to the fact that the literature in the last 20 years shows contradictory points of view regarding the morphology and relations among the nasal cartilages in man, gross, semi-macroscopic and light-microscopic surveys were carried out in 20 adult and fetal human noses. It was concluded that the septodorsal cartilage is made up of only one block. The attachment of the septodorsal cartilage to the nasal bones takes place from 2 to 5 mm in the inner aspect of the latter. The distal and fibrous portions of the lateral cartilage and the greater alar cartilages act as valves.
