Abstract: Novel oligonucleotides useful as primers and probes in the detection and identification of ricin toxin gene and gene product are provided. A method and kit for detecting and identifying a nucleic acid from Ricinus communes are also provided.

Abstract: An orthopedic cerclage device for binding and stabilizing fractured bone segments is formed from an elongate fabric strip adapted to be tied tightly about the bone to secure the fractured bone parts together. The fabric strip has a plurality of transverse ribs raised from one face of the fabric. The strip is wrapped tightly about the bone with the ribbed surface engaging the bone. The strip is secured in place by a locking member. The primary pressure applied to the bone by the device is at the ribs so that the segments of the strip between the ribs do not adversely cut off vascular circulation in the bone. The fabric structure of the device also allows bone tissue to grow into the interstices of the device thereby incorporating it intimately into the healed bone. Also disclosed is a novel knitted fabric in which the ribs are knitted integrally into the stitch pattern of the fabric.

Abstract: In a process for surgically reconstructing the anterior cruciate ligament of the knee to restore its normal stability, the damaged ligament is removed and holes are formed in both the tibia and the femur. The holes extend through the knee joint with their adjacent ends terminating approximately at the points of origin of the removed ligament. A strip is partially severed from the patellar tendon, except at its lower end where it remains attached to the tibia. The tendon strip is shaped and sutured into a tubular configuration and fitted into an open-ended, tubular sleeve of Dacron open mesh fabric. The composite Dacron fabric and the tendon segment is inserted into the hole provided in the tibia, fitted through the knee joint and then advanced upwardly through the hole in the femur. The upper end of the composite insert is fastened in place by means of a bone member fitted into the upper end of the hole in the femur to wedge the upper end of the insert in fixed position.
