Plasma exchange was performed in patients with recurrent colon cancer with evaluable liver metastasis or abdominal tumor with dissemination. This therapy was undertaken a total of 19 times in 11 cases. The cases were divided into effective and ineffective cases according in terms of the clinical effects, and changes in blood parameters and prognosis were examined in each case. Subjective symptoms, such as increase in appetite and disappearance of general fatigue or pain, were remarkably improved in 6 cases, and these patients were allowed to be discharged from the hospital. Marked regression of hepatomegalia was observed in 2 cases out of these 6 cases, but no remarkable effect was noted in patients with abdominal dissemination. In the effective cases the following parameters were significantly improved; beta- and gamma-globulin of serum protein fractions, IgG, IgA and IgM of immunoglobulin, alpha 2-macroglobulin, ceruloplasmin, and transferrin. However, since these effects are temporal and short-lived, one must consider applying plasma exchange therapy in conjunction with anticancer drugs, and the like. Plasma exchange seems applicable to cases of colon cancer with metastasis in the liver, because this therapy showed improvement in clinical symptoms, decreased hepatomegaly and prolonged survival.

The recognition of Menkes' kinky hair syndrome, trichopoliodystrophy, may present problems in the early neonatal period. The serum copper, and ceruloplasmin levels are within the range of normal infants in the first week of life; they are higher than normal in the cord blood of affected infants and fall gradually. Pili torti may only develop later, as the primary fetal hair is normal. The baby may appear bald, or both normal and abnormal hair may be found in different areas of the skull. The roentgenographic signs of wormian bones in the skull, metaphyseal spurring of the long bones, and diverticuli of the bladder develop progressively and may not be seen until after 6 weeks of age. However, diagnosis is possible in the neonatal period, if male infants with unexplained hypothermia, hypotonia, septicemia, or seizures are investigated by serum copper and ceruloplasmin levels after 1 month of age.

When Wilson's disease presents as fulminant hepatic failure, it may be extremely difficult to differentiate from other causes of hepatic insufficiency. A recently described diagnostic biochemical profile (elevated serum and urine copper levels, mild transaminase elevation, very high bilirubin levels, and low hemoglobin with intravascular hemolysis) was employed to diagnose this form of Wilson's disease prior to death in a young woman without Kayer-Fleischer rings and with a normal serum ceruloplasmin level. Since hepatic transplantation now offers a possible cure for this previously uniformly fatal form of Wilson's disease, it should be considered the treatment of choice for this disease entity. Combined with the availability of hepatic transplantation, this patient's temporary improvement and unusually long survival of four months further emphasizes the importance of this diagnostic profile in recognizing Wilson's disease quickly and accurately when it presents as fulminant hepatic failure.

Three patients with Menkes' disease, an inherited disorder of copper transport, were studied to determine whether the copper deficiency was associated with a lipoprotein disorder. Hypocuprinemia was documented in all three cases. Two patients had severe copper and ceruloplasmin deficiencies, whereas the third patient had a less severe deficiency. Hypertriglyceridemia was observed in the first patient, and elevations in triglyceride, cholesterol, apolipoprotein B (ApoB), and apolipoprotein C-III (ApoC-III) occurred predominantly in the very low density lipoprotein fraction (VLDL). This patient had normal lipoprotein lipase activity but mild glucose intolerance. The second patient had a borderline high cholesterol level with normal plasma triglycerides and apolipoproteins, whereas the third patient appeared to have normal total cholesterol but slightly higher triglycerides with elevated plasma apolipoprotein E (ApoE). No striking differences were observed in the chemical composition of all lipoprotein subfractions between patients and controls except that the neutral lipid content of VLDL was higher in patients than in controls. The ApoB was initially normal in molecular weight but degraded faster than the controls during storage. The appearance of the major low density lipoprotein (LDL) fraction of the first two patients was opaque white, in contrast to clear yellow in the third patient and in the age- and diet-matched controls. This abnormal appearance of LDL in these patients was associated with low plasma levels of beta-carotene and ceruloplasmin. These findings suggest that decreased serum copper levels may be associated with lipid and lipoprotein abnormalities and may enhance lipid peroxidation of LDL accounting for the color change.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors report a case of Menkes' syndrome, probably the first one described in Brazil. The patient, a 15-month-old boy, showed pili torti, early progressive psychomotor deterioration and seizures. Serum levels of ceruloplasmin and copper were very low. Neuroradiological and roentgenological examinations revealed diffuse cerebral atrophy, arterial changes and bone abnormalities. At the post-mortem examination the more consistent findings were cerebral atrophy, neuronal loss in the thalamus and above all cerebellar cortical lesions. The disease has a sex-linked recessive inheritance and is believed to be caused by an inborn error of copper metabolism, perhaps subordinated to changes of proteins which carry copper to different tissues. The relevant literature in relation to the pathogenesis is reviewed.

Serum proteins and lipoproteins were determined in 23 menopausal females after surgery for early forms of breast cancer and the results compared with data from a matched group of randomly selected healthy females. The patients were randomly divided into 2 groups, one serving as a control group, the other receiving 40 mg tamoxifen daily for 2 months. Breast cancer patients were found to have significantly higher concentrations of serum cholesterol than controls (7.90 +/- 1.15 vs. 6.87 +/- 1.18 mmol/l, P less than 0.001), which was the result of a 16% higher concentration in LDL cholesterol (P less than 0.05) and a 13% higher concentration in HDL cholesterol (P less than 0.05). During tamoxifen therapy total TG tended to increase, whereas total cholesterol fell. Significant lipoprotein changes were found in the LDL fraction where LDL-TG increased from 0.46 to 0.56 (P less than 0.01) and LDL cholesterol fell from 5.11 to 4.10 mmol/l (P less than 0.001). During tamoxifen therapy haptoglobin and orosomucoid concentrations fell significantly (P less than 0.01), whereas those of alpha-antitrypsin and ceruloplasmin increased (P less than 0.001). Factors such as diet and weight may explain the differences between breast cancer patients and controls. The tamoxifen-induced changes indicate that this anti-oestrogen exerted a mild oestrogen-like effect with regard to protein and lipoprotein metabolism.

Twenty male alcoholics aged 29 to 69 years (mean 45.80 + SD 10.97) were compared with controls for serum zinc, copper, and ceruloplasmin levels. The serum zinc level of the alcoholic patients was significantly lower than that of the control group (t = 3.3005, p less than 0.005). The serum copper and ceruloplasmin levels of the alcoholics tended to be higher than those of the controls, but the difference was not statistically significant. A significantly positive correlation between serum zinc and albumin levels (r = 5.41, p less than 0.01) was also found. The nutritional state of the alcoholics may not be an adequate explanation for their low serum zinc level. It is suggested that further research on alcohol as a toxic agent might focus on trace element-containing enzymatic defects in brain peptides and hormones to promote fuller understanding of the psychopathology associated with alcohol abuse.

Calves clinically affected with experimentally induced Johne's disease exhibited elevation of caeruloplasmin oxidase activity, and marked depression of alpha-mannosidase activity during the period when clinical signs of the disease were most prominent. Changes in serum copper levels and alkaline phosphatase activity were closely correlated with the elevation of caeruloplasmin oxidase activity, and depression of alpha-mannosidase activity. The pattern of these changes was similar to nutritional and metabolic changes described previously in acute infectious conditions in man and animals.

It has been known that there is remarkable antioxidant activity in the human sera, especially those in inflammation and pregnancy. In the present investigation, various sera were examined for the antioxidant activity with the aid of cultured cells. It was recognized that the serum added to the culture medium protected cells from harmful action of active oxygen generated by a hypoxanthine-xanthine oxidase (HX-XO) system. The inflammatory serum has the greatest protective power, followed by pregnant and normal sera in this order. The antioxidant activity of the serum was inversely related to the Fe concentrations. The addition of ceruloplasmin with SOD action could not inhibit the tissue damage, while addition of catalase or hemoglobin with catalase activity could inhibit it. The protective effect was valid against not only HX-XO, but also H2O2. These results show that the chief active oxygen to cause cell damage is H2O2 and the scavenger antioxidants in the serum are hemoglobin and catalase.

Inclusion of some glycosides, gangliosides and ceruloplasmin into large (300-400 nm in diameter) unilamellar liposomes was performed. About 100% of the gangliosides, 30-50% of ceruloplasmin and 3-5% of the glycosides were incorporated into the phospholipid vesicles under these conditions. The liposomes containing ceruloplasmin or gangliosides, in contrast to the glycoside-containing vesicles, were precipitated in the presence of agglutinin from Ricinus communis. The interaction of phospholipid vesicles containing gangliosides with rat hepatocytes "in vitro" was studied. It was found that the incorporation of gangliosides into the liposomal membrane increased the liposomal lipid uptake by 50% as can be judged from the uptake of radioactive cholesterol. Possible mechanisms of incorporation of carbohydrate-containing compounds into liposomes are discussed. It is concluded that beside the density of carbohydrates the degree of their exposure on the liposomal membrane is important for specific interactions of the vesicles with lectins.
