ticks are vectors of some important arthropod-borne diseases in both fields of veterinary and medicine, such as lyme, tularemia, rocky mountain spotted fever, and some types of encephalitis as well as crimean congo hemorrhagic fever (cchf). iran is known as one of the main foci of cchf in west of asia. this study was conducted in darrehshahr county because of the development of animal husbandry...

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...

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...

Sets of four kudus were shot and examined for arthropod parasites at approximately monthly intervals from April 1981 to March 1983 in the southern part of the Kruger National Park, eastern Transvaal Lowveld. These animals harboured 10 ixodid tick species of which Boophilus decoloratus followed by Amblyomma hebraeum were the most abundant. The seasonal abundances of these ticks and of Amblyomma ...

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...
