During the conditioning phase (4 days, 72 h apart), 32 male Long Evans rats were injected intraperitoneally with either isotonic saline (NaCl), lithium chloride (LiCl, 127 mg/kg), saline plus 2% saccharin (NaCl + Saccharin), or lithium
chloride plus 2% saccharin (LiCl + Saccharin) https://www.selleckchem.com/products/ly3039478.html immediately prior to a 30 min exposure to a novel context. 72 h following the final conditioning day, each animal was re-exposed to the context on a drug-free test day. The next day, animals received a 24 h 2-bottle preference test with a choice between water and a palatable saccharin solution. Results showed that animals treated with LiCl during conditioning, with or without saccharin, displayed significantly higher levels of conditioned gaping responses, indicative of nausea, upon re-exposure to the context, relative to NaCl and NaCl + Saccharin controls. Animals administered LiCl + Saccharin during conditioning also displayed significant conditioned taste avoidance to the saccharin solution during the two bottle choice test. These results indicate that systemic administration
(intraperitoneal) of a LiCl + Saccharin solution is effective in simultaneously conditioning toxin elicited nausea to both internal (taste) and external (context) cues. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“Purpose: Renal oncocytosis is BV-6 in vitro a rare pathological condition in which renal parenchyma is diffusely involved by numerous oncocytic nodules in addition to showing a spectrum of other oncocytic changes. We describe our experience with renal oncocytosis, focusing on management and outcomes.
Materials and Methods: A total of 20 patients with a final pathological diagnosis of renal oncocytosis from July 1995 through June 2009 were included in the analysis. Patient demographics, intraoperative variables and postoperative outcomes are reported.
Results: Median age at nephrectomy was 71 years (IQR 59-75). Of the patients 15 (75%) had bilateral disease. There were 23 operations (9 right side, 14 left side) performed on 20 patients, and of these procedures 13 (57%) were partial nephrectomies and 10
(43%) were radical nephrectomies. Median dominant tumor mass diameter was 4.1 cm (IQR 3-6.4, range 1 to 14.6). The most common dominant tumor histology was hybrid tumor between oncocytoma and chromophobe renal cell carcinoma in 13 of 23 specimens (57%), followed by chromophobe renal cell carcinoma Tozasertib price in 6 (26%), oncocytoma in 3 (13%) and conventional renal cell carcinoma in 1 (4%). Ten patients (50%) had preexisting chronic kidney disease before nephrectomy and chronic kidney disease developed in 5 more after surgery. After a median followup of 35 months no patients had metastatic disease.
Conclusions: Patients with renal oncocytosis usually present with multiple and bilateral renal nodules. Half of the patients had chronic kidney disease at diagnosis and 25% had new onset of chronic kidney disease. No patient had distant metastatic disease during followup.
