Quantitative study of vascularity in Walker carcinoma 256.

چکیده
SUMMARY Vascularity in rat Walker carcinoma 256 was studied quantitatively by a radioisotopic method. Functional intravascular volume and extravasation of plasma protein per unit of tumor mass decreased as the tumors grew. The intravascular volume that we obtained with 5 ' Cr-labeled RBC's was 0.0079 ml/g of tumor mass, which was less than 10% of the value obtained by other workers using dextran. A possible reason for this discrepancy and evidence in support of our results are discussed.

An experimental study of necrosis in tumors.
Factors that regulate the amount of viable tumor an animal can support have been studied in rats bearing Walker carcinoma 256. There is a maximum amount of viabletumor an animal can support, but continued growth of tumor resulting in increase in the amount of necrotic tumor occurs until death of a rat bearing Walker carcinoma 256. The number and location of tumors in an animal do not significan...
متن کاملHormone-releasing Hormone Changes through Ectopical Secretion of Luteinizing Walker 256/S Carcinosarcoma Causes Osteoporosis-like
We have shown that Walker 256/S mammary carcinoma caused osteoporosis-like changes in young female rats, accompanied by low serum estradiol and hypercalciuria without changes in the serum levels of calcium, phosphorus, and parathyroid hormone-related peptide. In this study, we investigated the cause of bone loss after Walker 256/S inoculation into female 6-week-old Wistar Imamichi rats, focusin...
متن کاملThe competitive effect of canavanine on utilization of arginine in growth of Walker carcinosarcoma 256 cells in vitro.
Accordingly, it was of interest to study argininecanavanine relationships in actively multiplying tumor cells. Arginine has been shown to be essen tial for the growth of the Walker carcinosarcoma 256 in vitro (8) ; and, with the recent developments in tissue culture (9, 11) in this laboratory, it was possible to study the effects of canavanine on argi nine metabolism during tumor cell growth. T...

متن کاملCatabolism of xanthine and uracil in tumor-bearing rats.
The urinary excretion of allantoin and uric acid was greatly increased in rats bear ing Walker carcinoma 256. The increase was greater with more advanced tumor growth. A similar increase was also observed in the allantoin concentration of the plasma and liver of these rats. An increase in the RNA and DNA content and a decrease in the RNA/DNA ratio were found in the muscle of the tumor-bearing a...
