Morphologic Changes

Abstract The morphologic responses of the lymphoid system of the rabbit were studied. The results demonstrated: (a) the proliferation of a characteristic cell, the "hemocytoblast", within lymphoid centers; (b) architectural changes in lymph nodes and spleen, at first characterized by enlargement of follicles and germinal centers, later by effacement of normal landmarks and finally by reconstitution of lymphatic structures; (c) a barely perceptible plasmocytic response, especially in the first set reaction. These changes, although most pronounced in the lymph node proximal to the homograft, were also found later in distant lymph nodes and in the spleen. They arose more rapidly, were of greater intensity and were more persistent in the second set reaction than in the first set reaction. These findings indicated that transplantation immunity eventually invokes generalized morphologic changes in the lymphoid system. The events which followed a second set graft suggested that the second set phenomenon had the features of an anamnestic response.

The lymphatic system is very important in the immunological activities of the body. Clinicians confirm the diagnosis of infectious diseases by palpating the involved cutaneous lymph node for changes in size, heat, and consistency. Clinical pathologists diagnose systemic diseases through biopsies of superficial lymph nodes. In many parts of the world the goat is considered as an important source of milk and meat products.The lymphatic system has been studied extensively. These studies lack precise information on the natural morphology of the lymph nodes and their vascular and cellular constituent. This is due to using improper technique for such studies. A few studies used the SEM, conducted by cutting the lymph node with a blade. The morphological data collected by this method are artificial and do not reflect the normal three dimensional surface of the examined area of the lymph node. SEM has been used to study the lymph vessels and lymph nodes of different animals. No information on the cutaneous lymph nodes of the goat has ever been collected using the scanning electron microscope.

Morphologic Changes

The synergistic activity of antimicrobial combinants against aerobic and facultative microorganisms has been well documented. in comparison, few studies have been performed using obligate anaerobic isolates and antimicrobial combinants. For this study clinical strains of Bacteroides fragilis(BF) were selected to investigate both single/combinant drug activity and cellular morphologic changes when BF is exposed to Imipenem (I), Piperacillin (P), Cefpimizole (C), Imipenem/Piperacillin (I+P), and Imipenem/Cefpimizole (I+C).

Comprehensive Study

A comprehensive study of the microvasculature of the normal rabbit bladder, revealed unusual "capillary glomeruli" along the lateral walls. Here they are characterized as hemal lymph nodes using light microscopy, SEM, TEM, ink injection, and vascular casting.Bladders were perfused via a cannula placed in the abdominal aorta with either 2% glutaraldehyde in 0.1M cacodylate buffer (pH 7.4) for fixation, 10% India ink in 0.9% saline and 0.1M phosphate (pH 7.4) for vessel tracing, or resin (Mercoximethylmethacrylate: catalyst, 4:1:0.3; Ladd Research Industries) for vascular corrosion casting. Infusion pressure was 100mm Hg. Fixed tissue was sectioned from epon-araldyte resin, and stained with toluidine blue for light microscopy, and lead and uranium for TEM. Ink injected tissue was photographed directly from saline-filled bladders illuminated from below. Resin-filled tissue was macerated in 5% KOH and distilled water. Casts were critical point dried, sputter coated with goldpalladium, and examined by routine SEM at 10 KV.
