fibrosarcoma/albumin

Albumin clearance and blood flow were measured in normal tissues and in fibrosarcomas by means of a multiple tracer method in intact male rats. Sarcomas implanted in testes had higher albumin clearances than the same tumours implanted in skeletal muscle, 59 and 26 microliters min-1 per 100 g,

Our recent studies indicated that Rhodamine fibrosarcoma (RdF) tissue of rats accumulated large amounts of albumin and transferrin and that these proteins were essential for growth of RdF cells in primary cultures in serum-free medium. Therefore, the localizations of albumin and transferrin

Primary Rhodamine fibrosarcoma (RdF) cells from rats were shown to grow in serum-free medium supplemented with basic fibroblast growth factor (bFGF), albumin, and transferrin, all of which were purified from RdF tissue. Their growth rate with these supplements was similar to that of cells in medium

Accumulation of free fluid in the peritoneal cavity is called ascites. The first step in identifying its etiology is to determine the serum-ascites albumin gradient (SAAG). According to this parameter, a high SAAG is regarded as a gradient greater than 1.1 g/dL. This condition has some differential

Recent evidence suggests that common prognostic factors predicting disease progression and survival in soft tissue sarcomas (STS) are not applicable to all STS entities, indicating the need for histotype specific evaluation of new prognosticators. This study aimed at evaluating preoperative serum

A technique is described for the dissociation and fractionation by isopycnic centrifugation (4,000 x g, 60 minutes, 4 degrees C) in linear bovine albumin density gradients (12 ml, pH 5.2 real osmolality 333 mmol/Kg water, 1.030-1.075 g/cm3) of cells ( less than or equal to 3 x 10(7)/gradient)

Blood flow measurements following i.v. infusion of iodo-antipyrine labelled with 14C(14C-IAP) and blood volume measurements following i.v. injection of 125I human serum albumin and 51Cr-labelled red blood cells were made in a transplanted rat fibrosarcoma for comparison with various normal tissues.

Tumor blood volume (TBV) is an important factor in the metabolism of a tumor and in its response to therapy. Until recently, the only methods to determine TBV were highly invasive and many involved radioisotopes. In this study, a perfluorocarbon (PFC) emulsion, Oxypherol, was monitored by 19F

The alterations induced on the pool sizes of five phospholipid metabolites, glycerol 3-phosphorycholine, glycerol 3-phosphorylethanolamine, phosphorylcholine, sn-glycerol 3-phosphate, and choline were studied by nuclear magnetic resonance (NMR) spectroscopy in murine tumors injected with recombinant

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 transplantable methylcholanthrene-induced fibrosarcoma of female BALB/c mice (the MC-2 fibrosarcoma) was dissociated by combined mechanical and enzymatic means, then fractionated by isopycnic centrifugation in linear albumin gradients. In some experiments recovered cells were both cultured in soft

The effect of a protein-free diet (PF) or a restricted intake of chow (RI) and subsequent host repletion with total parenteral nutrition (PF-TPN, RI-TPN) on tumor growth and polyamine metabolism of fibrosarcoma-bearing rats was examined. Host weight was significantly reduced by PF and RI. Tumor

The kinetic release of therapeutically active Adriamycin from two different heat-stabilized preparations of magnetically responsive albumin microspheres (1 micron) has been evaluated using a rapid in vitro bioassay-harvesting system. Release products are added to freshly plated monolayers of a

Albumin distributions and turnover rates have been studied using (131)I labelled tracer material in rabbits with Vx2 carcinoma and rats bearing SP7 fibrosarcoma in comparison with control animals. Albumin concentrations were reduced in the tumour bearing animals but plasma volumes increased as the

The internalization of near-infrared fluorescently labeled cargos into living cells and tissues allows a highly sensitive detection without interference from skin, porphins or other fluorescent cell and tissue compounds. In this study, the uptake of labeled bovine serum albumin and an antibody, into
