Patients with an accessory kidney are characterized by an excessive number of kidneys. The ureter of the accessory kidney either drains separately into the bladder or merges with the ureter of the main kidney. In our case, interestingly, the ureter of the left main kidney drained directly into the accessory kidney and the ureter of the latter was the common drainage route for both. The drainage...

Previous studies have suggested that in vitro and in vivo immune responses are defective in Peyer's patch (PP) as a result of a deficiency in accessory cell number or function. However, we report here that enzymatic dissociation of PP does release a cell population with accessory activity in oxidative mitogenesis, i.e., the proliferation of periodate-modified T cells. The accessory activity pre...

Cell surface carbohydrates are differentially expressed by discrete subpopulations of primary sensory axons in the mammalian main and accessory olfactory systems. It has been proposed that these carbohydrates provide a glycocode which mediates the sorting of these sensory axons as they project from the olfactory neuroepithelium to their central targets in the main and accessory olfactory bulbs ...

Congenital anomalies of the spleen range from splenic lobulation, to accessory spleen to polysplenia. Though most of these anatomical variants have no clinical significance, an accessory spleen may simulate a tumor in the adrenal gland, pancreas, stomach or intestine. Alternatively, a missed accessory spleen may be the site of the relapse of a hematological disorder. We, therefore, assessed ret...

An accessory spleen (AS), or splenunculus, is a small nodule of splenic tissue found outside of the spleen. Post-mortem examinations, also known as autopsies, are carried out to identify a cause of death, and to assess the state of the organs of the deceased. We present two incidental cases of splenunculi, one localized in greater omentum and a second one localized in the hilum of the spleen, d...

This review compiles present knowledge of the structure and molecular composition of the enigmatic cytoplasmic organelles called accessory nuclei. Most typically, they are found in the perinuclear cytoplasm in oocytes of insects and several other invertebrates. Accessory nuclei originate by budding of the oocyte nucleus (germinal vesicle) and are surrounded by an envelope identical to the nucle...
