Seroprevalence of human papillomavirus type 16 in pregnant women.

Objective: To determine the seroprevalence of and risk factors for human papillomavirus (HPV) type 16 capsid antibodies in a large cohort of pregnant women.

Methods: Antibodies against in vitro produced HPV-16 capsids were measured in stored sera from 2597 pregnant women enrolled from 1984 through 1989 in the Vaginal Infection and Prematurity Study, New Orleans site.

Results: Women in this study were primarily black (83.

The role of Na-hylan in reducing postsurgical tendon adhesions: Part 2.

Na-hylan, a chemically modified sodium hyaluronate jelly, was studied mechanically and histologically as a surgical device to diminish tendon adhesions in rabbit extensor hallucis longus tendons after severe surgical trauma. Na-hylan jelly of high viscoelastic properties was found to be highly effective in decreasing tendon adhesions. Na-hylan jelly of low viscoelastic properties was not effective in diminishing adhesion formation.

The role of Na-hylan in reducing postsurgical tendon adhesions.

Na-hylan, a chemically modified sodium hyaluronate jelly, was studied mechanically and histologically as a surgical device to diminish tendon adhesion in the rabbit long toe extensor three weeks after surgical abrasion. This device was found to be highly effective (55% of treated tendons formed no adhesions compared to 5% of controls, and only 18% formed severe adhesions compared to 62% of controls). No gross or histologic evidence of significant acute or chronic inflammatory reaction to the Na-hylan was found.
