OBJECTIVE To evaluate the frequency of inadvertent penetration of the digital flexor tendon sheath (DFTS) and/or distal interphalangeal joint (DIPJ) when using a direct endoscopic approach to the navicular bursa, and to evaluate an alternate direct approach to the navicular bursa. STUDY DESIGN Cadaveric study. SAMPLE POPULATION Equine cadaver limbs (n = 40 for direct; n = 12 for alternate a...
HOSHI, H. Effect of Inoculation of Bursa Cells on the Splenic Lymphoid Tissue of Bursectomized and X-irradiated Chickens. Tohoku J. exp. Med., 1972, 108 (2), 113-121 Bursectomized and X-irradiated chickens were given intraperitoneal inoculation of live bursa cells in an attempt to restore the periellipsoidal lymphoid cells in their spleens. An injection of viable cells prepared from autologous ...
An operation for chronic prepatellar bursitis is described in which only the posterior wall of the bursa is excised, thus preserving, undamaged, healthy and normally sensitive skin. This procedure is easier and less traumatic than complete excision of the bursa and results in fewer complications. It is suggested that removal of tha anterior wall of the bursa results in unnecessary and harmful i...
In the chicken, the bursa of Fabricius is essential for the development of lymphoid cells that will synthesize and secrete both IgM and IgG (1-3). WheI1 newly hatched chickens are bursectomized and irradiated, they fail to synthesize serum immunoglobulin(s) (Ig) 1 even though the expression of cell-mediated immunity remains normal. Hence, the bursa of the chicken provides an excellent experimen...
Introduction: Synovial osteochondromatosis of a bicipital radial bursa is a very rare condition. We report herein a case of synovial osteochondromatosis of a bicipital radial bursa. Presentation of Case: A 52-year-old man presented with a 20-year history of a slowly enlarging mass on the left elbow. Radiographs revealed multiple oval calcified lesions in the anterior aspect of the elbow. A mass...
Androgenic hormones induce inhibition or regression of the bursa of Fabricius in the chick embryo. The high doses of hormones necessary to this involution raises the question of the processes involved and their putative role in the normal development of the bursa. If androgens play a role it is mediated by receptor sites in target cells. Using an autoradiographic technique, receptor sites for a...
Three levels (high, low and control) of northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), were maintained on White Leghorn hens for 24 weeks. The hens were then treated with carbaryl to eradicate the mites, were induced to molt, and were reinfested with mites 9 weeks later. Subsequent levels of mites on the three groups showed that the degree of acquired immunity was related...
Persistent adaptive challenges are often met with the evolution of novel physiological traits. Although there are specific examples of single genes providing new physiological functions, studies on the origin of complex organ functions are lacking. One such derived set of complex functions is found in the Lepidopteran bursa copulatrix, an organ within the female reproductive tract that digests ...

Association between enlarged iliopsoas bursa and hip lesions such as osteoarthritis of the hip or femoral head necrosis is infrequently seen. Enlarged iliopsoas bursa with a rapidly destructive arthropathy is claimed to be seen only in patients with rheumatoid arthritis. In this paper, we report a patient with a rapidly destructive arthropathy accompanied by an enlarged iliopsoas bursa that has...
