Mechanical evaluation of the Dwyer screw-cable attachment.

A critical portion of the Dwyer technique is the crimping of the screw head to prevent the cable from slipping. Initally, Dwyer designed a hydraulic mechanism to crimp the screw head. However, this instrument was cumbersome to use and presented potential sterility problems. Today the Simmons crimper is used by the majority of orthopaedic surgeons. It is the purpose of this paper to report the studies conducted on 1) different materials used for the fabrication of the screws, and 2) the significance of the variations in the jaw opening using the Simmons mechanical crimper.

Difference between influences of homologous and heterologous maternal antibodies on response to serotype-2 and serotype-3 Marek's disease vaccines.

Marek's disease (MD) vaccines representing serotypes 2 (SB-1 strain of MD virus) and 3 (FC-126 strain of turkey herpesvirus) were administered to 1-day-old MD-susceptible chicks that either were free of antibodies or carried maternally derived antibodies against SB-1, FC-126, or a serotype-1 MD virus, CU-2 strain. Homologous antibodies delayed the development of vaccine virus viremias and inhibited vaccinal immunity, as judged by protection against challenge with the virulent JM-10 strain of MD virus 7 days postvaccination. Heterologous antibodies had little effect on vaccine responses. Antibodies were shown to interfere with both cell-associated and cell-free vaccine virus.
