Protein Electrophoretic Analyses of Serum of Cancer Patients.
نویسنده
چکیده
The mean relative proportions of a number of blood serum protein fractions assessed electrophoretically are altered in active cancer. The changes in number and degree are generally greater than in other diseases; this may be a reflection of the seriousness of the condition and the extent of tissue involvement. A relative lowering of the proportion of albumin and an increase in that of the various globulins in “active” cancer was absent or much less apparent in treated cases. Significant changes differ according to location of the malignancy. Proportions of the a-globulins were not elevated in cancer of the gastrointestinal tract nor were those of the y-globulins in prostatic cancer. Within the 22-globulins the central subfraction proportion was elevated most where tissue involvement was greatest, although in breast or prostate cancer the most pronounced alteration occurred in the proportion of the first z2-globulin subfraction. The subfraction of ‘/-globulin increased in proportion in cancer of the gastrointestinal tract differed from that elevated in cancer of the lung. Further refinement in fractionation techniques may reveal major differences in the serum protein distribution in different neoplasms. A considerable elevation of the 22-globulin proportion above the normal may be regarded as a sign of a poor prognosis. Age had little significant effect with the exception of a rise in the third 3-globuIin subfraction proportion, which went through a maximum in the 50-59 year age group. The relative concentration of this same fraction was elevated in cardiovascular disease in hypertension and hypercholesterolemia.

Effect of water salinity on total protein and electrophoretic pattern of serum proteins of grass carp, Ctenopharyngodon idella
In this study the effects of water salinity on serum total protein and its components in grass carp were investigated. The aim of this study was to determine the effect of salinity tolerance of fish on total serum protein level and its components as an indicator of liver and kidney activity. One hundred and twenty grass carp were divided into four groups, randomly. The first three groups were r...

Abstract Background : Cancer has not been elucidated in colerectal site. C-reactive protein (CRP) is a product synthesized in hepatocytes and has been reported to be up-regulated by such proinflammatory cytokines as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor (TNF). The significance of a preoperative serum elevation was evaluated using CRP as a predictive i...

Electrophoresis is a meticulous method in para-clinical science but has received less attention. In this study, the protein profile of synovial fluid of carpal joint and blood serum in buffalo was detected. Sampling was performed by arthrocentesis of 80 left and right forelimbs and obtaining blood serums of 40 Bubalus bubalis in Ahvaz industrial slaughterhouse. Samples were str...
