BACKGROUND Milky spots in the greater omentum of some animals are well organized perivascular infiltrates of leucocytes, and are considered to have characteristics of secondary lymphoid tissue. To determine whether milky spots in the human greater omentum can also be regarded as secondary lymphoid tissue, we studied milky spots in an unstimulated state. (More)
Multifocal fibrosclerosis, as the name implies, concerns disseminated fibrous processes that manifest as Riedel's thyroiditis, idiopathic retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, and pseudotumor of the orbit. Certain cases of fibrosis of the parotid gland, the lacrimal glands, and the lung may belong in the same category. The(More)
Concentrations of 5-fluorouracil (5-FU) and its active metabolite 5-fluoro-2'-deoxy-5'-monophosphate (FdUMP) were measured in biopsy specimens of tumor tissue, normal mucosa, metastatic liver nodules, and normal liver tissue obtained from 39 patients and in two murine colon tumors (colon 26 and colon 38) after a single injection of 5FU at a therapeutic dose(More)
Intraoperative ultrasonography (IOUS) of the liver is a very useful tool during surgery for gastrointestinal tumors or hepatic tumors. In a prospective study of 82 elective operations for 57 gastrointestinal tumors and 25 hepatic tumors or metastases, we compared IOUS with preoperative ultrasonography, CT-scanning and MRI. IOUS supplied additional(More)
The muscular dystrophies (MDs) are genetic disorders of muscle degeneration due to mutations in genes that encode a wide variety of proteins. Dysferlinopathy are characterized by the absence of dysferlin in skeletal muscle and an autosomal recessive mode of inheritance. Both histological and ultrastructural pathology have been well established in(More)
The evidence that Kupffer cells are capable of controlling metastatic growth in the liver in vivo is largely circumstantial. The best approach when studying natural cytotoxicity activities of Kupffer cells is to investigate the effect of Kupffer cell elimination on tumour growth. Until now it has not been possible to eliminate Kupffer cells without(More)
The gastrointestinal tract, besides being the organ responsible for nutrient absorption, is also a metabolic and immunological system, functioning as an effective barrier against endotoxin and bacteria in the intestinal lumen. The passage of viable bacteria from the gastrointestinal tract through the epithelial mucosa is called bacterial translocation.(More)
Proliferation variables such as mitotic activity and the percentage of S-phase cells have been shown to be of prognostic value in many tumors, especially in breast cancer. However, some studies reported a decrease in mitotic activity caused by delay in fixation of the tissue. In contrast, other studies showed that the identifiability of mitotic figures(More)
OBJECTIVE The authors tested the hypothesis that the beneficial effects of the endotoxin-binding agent cholestyramine on the postoperative course in rats that had undergone a partial hepatectomy was the result of improvement of cellular immune functions. SUMMARY BACKGROUND DATA Major liver resection is associated with severe postoperative complications(More)
BACKGROUND Neoadjuvant chemotherapy improves survival in patients with locally advanced breast cancer (LABC). Usually three to four cycles of conventional-dose neoadjuvant chemotherapy are administered prior to local therapy, and another three cycles thereafter. In an attempt to improve results, we increased the dosages and applied GM-CSF, which, besides(More)
