In the serum of 27 patients with malignant lymphogranulomatosis the authors determined the serum level of glycoproteid-carbohydrate components (hexose, hexosamine, sialin acid, and seromucoid) and the concentration of 11 different glycoproteids. In the early stage of the disease the immunoglobulin level is moderately increased in the serum, whereas a diminution can be observed in stage IV. The concentrations of ceruloplasmin, alpha-2-macroglobulin and orosomucoid were already increased significantly in stage III. The increase did not continue in stage IV. In the final stage of the disease the concentrations of alpha-1-antitrypsin and haemopexin turned out to be increased considerably. A significant decrease in the transferrin level could be registered in stage III with this diminution also continuing in the further course. Changes of beta-C-globulin and haptoglobin concentrations could not be evaluated statistically. The content of carbohydrate components in the glycoproteids will already increase in the early stage of the disease with this increase continuing in the further course. Among histological types there was a more significant increase of immunoglobulins in those forms rich of lymphocytes.

To evaluate metabolic functionality of monocytes and lymphocytes in Hodgkin's disease (HD) we studied 3 enzymes of the intermediary metabolism, G-6-PDH, PHI, ICDH, and the acid hydrolases, NAG and ACP. These enzymes were measured in purified cell fractions of 9 patients with advanced disease and 11 normal controls. The cells were isolated with cell scatter-monitored counterflow centrifugation. Enzymes were measured in the cell lysates by means of fluorimetric microassays. In the monocytes of HD patients a significantly increased G-6-PDH activity was found (P less than 0.01), indicating an enhanced activity of the hexose monophosphate shunt. The other enzymes showed no clear differences compared to normal controls. The lymphocytes of HD patients showed a significantly augmented activity of both G-6-PDH (P less than 0.001) and PHI (P less than 0.01), pointing to an increased HMPS and glycolytic activity. These findings are in support of an enhanced metabolic activity of both monocytes and lymphocytes in HD.

This study assessed the changes in the isoprenoid pathway and its metabolites digoxin, dolichol and ubiquinone in neoplasms (CNS astrocytomas - glioblastoma multiforme and high grade non - Hodgkin's lymphoma). The following parameters were assessed-isoprenoid pathway metabolites, tyrosine and tryptophan catabolites, glycoconjugate metabolism, RBC membrane composition and free radical metabolism. There was an elevation in plasma HMG CoA reductase activity, serum digoxin and dolichol and a reduction in RBC membrane Na+-K+ ATPase activity, serum ubiquinone and magnesium levels. Serum tryptophan, serotonin, nicotine and quinolinic acid were elevated while tyrosine, dopamine, noradrenaline and morphine were decreased. The total serum glycosaminoglycans and glycosaminoglycan fractions (except dermatan sulphate in the case of CNS astrocytomas), the activity of GAG degrading enzymes and glycohydrolases, carbohydrate residues of glycoproteins and serum glycolipids were elevated. HDL cholesterol showed a significant decrease and free fatty acids & triglycerides were increased. The RBC membrane glycosaminoglycans, hexose and fucose residues of glycoproteins and phospholipids were reduced. The activity of all free radical scavenging enzymes, concentration of glutathione, iron binding capacity and ceruloplasmin decreased significantly while the concentration of malondialdehyde (MDA), hydroperoxides, conjugated dienes and NO increased. The concentration of alpha tocopherol was unaltered. Membrane Na+-K+ ATPase inhibition due to elevated digoxin, altered membrane structure and digoxin related tyrosine / tryptophan transport defect leading to increased levels of depolarising tryptophan catabolites and decreased levels of hyperpolarising tyrosine catabolites can lead to alteration in intracellular calcium/magnesium ratios and oncogene activation. Intracellular magnesium deficiency can produce defective microtubule related spindle fibre dysfunction and chromosomal non-dysjunction contributing to neoplastic cellular polyploidy and aneuploidy. Digoxin induced tryptophan/tyrosine transport defect can alter neurotransmitter patterns with increased serotonin, quinolinic acid, nicotine & glutamatergic transmission and reduced dopamine, morphine and noradrenaline levels leading to oncogenesis. Glycoconjugate metabolism is altered by elevated dolichol levels and magnesium depletion consequent to Na+-K+ ATPase inhibition. There is a qualitative alteration in proteoglycans and glycoproteins, defective membrane formation and structure and reduced lysosomal stability leading to disordered contact inhibition and tumour antigen presentation contributing to oncogenesis. Digoxin induced alteration in intracellular calcium/magnesium ratios and low ubiquinone levels can lead to a mitochondrial dysfunction resulting in increased free radical generation and reduced scavenging & caspase-3 activation producing a P21 defect contributing to oncogenesis.
