Since recognition during the last decade that certain renal carcinogens can initially cause an accumulation of hyaline (protein) droplets in proximal tubules of male rats, it has become appropriate to establish whether this phenomenon of protein overload can also occur in rodent kidneys unrelated to
A transplantable tumour (HS-J) was established from a spontaneous histiocytic sarcoma found in a 24-month-old male F344 rat. Serial transplantations (seven generations) were made in syngeneic male and female rats by means of intraperitoneal or subcutaneous implants, with a 100% take rate. Rats given
A case of metastatic splenic haemophagocytic histiocytic sarcoma (HHS) in a 6-year-old neutered male flat-coated retriever is described. The main clinical findings were hypoalbuminaemia and regenerative anaemia. The diagnosis was based on histological features and expression of CD11d by the
Background: Localized splenic histiocytic sarcoma (HS) in dogs is a poorly understood disease, and could have longer survival times than disseminated or hemophagocytic HS. Understanding the clinical behavior of localized splenic HS can
Malignant histiocytosis (MH) is a true histiocytic disorder, whose identification is still based on too broad morphologic criteria. Using routine histology, cytochemical and immunohistochemical techniques on involved lymph nodes, 15 cases of MH have been investigated. Pleomorphism and cellular
Interferon (IFN)-γ plays an important role in antiviral, anti-proliferative, immunomodulatory and pro-inflammatory activities. However, the short therapeutic half-life of IFN-γ lessens its efficacy. Albumin fusion strategy is one of the most effective ways to improve the pharmacokinetic properties
Etoposide is bound to plasma albumin (94%). Previous studies have revealed altered protein binding of etoposide in cancer patients. This has clinical implications since only the free fraction is considered pharmacologically active. We have studied the etoposide protein binding in 11 children (eight
Renal tubular hyaline droplets developed in male and female F344 rats bearing a rat fibrosarcoma-derived transplantable tumor (SS). The droplets accumulated exclusively in the proximal renal tubular epithelia as eosinophilic granules of various sizes in hematoxylin and eosin-stained sections. The
A new isolate of reticuloendotheliosis virus (REV) from ducks, RU-1, was used to experimentally infect white pekin ducks. Embryonal or neonatal infection usually resulted in persistent viremias, no REV antibody development, and inability to mount antibody responses against bovine serum albumin (BSA)
Mice transgenic for human CD19 have been an important animal model to help understand the role of this molecule in B lymphocyte function. Previously, no lifetime studies had been performed to understand the effects of this CD19 over expression on the survival or spontaneous pathology within the
A retrospective study of 76 primary gastrointestinal lymphomas utilizing an avidin: biotinylated horseradish peroxidase complex (ABC) technique demonstrated 22 B-cell lymphomas, including two associated with alpha-heavy chain disease. Seven cases were classified as true histiocytic lymphomas based
In mice, hyaline droplets in renal proximal tubules have been associated with histiocytic sarcoma but have not been reported with lymphoma. Tissues from CD-1 mice in a 2-year carcinogenicity bioassay were examined microscopically. Twenty-five mice with hyaline droplets in renal tubules were
