The serum concentrations of the acute phase proteins, C-reactive protein, caeruloplasmin and haptoglobin were significantly higher in children with protein-calorie malnutrition than in age-matched controls, while the concentrations of alpha1 antitrypsin, alpha2 macroglobulin, transferrin and complement component C3 were significantly lower. During rehabilitation and treatment with antibiotics, C-reactive protein disappeared from the serum in most of the patients whilst the levels of caeruloplasmin and haptoglobin returned to normal values. On the other hand the serum concentration of alpha1 antitrypsin, alpha2 macroglobulin, transferrin and C3 showed significant increases. It is suggested that C-reactive protein and haptoglobin may provide useful indices of the presence or absence of infection in children with malnutrition.

Five glycoproteins have been measured in the blood of 145 diabetic patients with and without clinical evidence of complications. Patients with diabetic complications have higher glycoproteins levels particularly when expressed as a ratio to serum albumin levels. In 32 pairs of patients matched for age, sex, body weight, duration and treatment of diabetes, significantly higher haptoglobin, fibrinogen and caeruloplasmin levels were associated with the presence of diabetic complications, but blood glucose levels were not significantly different. Beta-lipoprotein levels were positively correlated with age and alpha2-macroglobulin levels with the duration of clinical disease, but the type of antidiabetic therapy administered did not significantly alter glycoprotein levels. It is suggested that rising levels of certain glycoproteins in the blood of diabetic patients may indicate the development of diabetic vascular complications, but a prospective study is required before it can be decided whether this change predates the clinical appearance of the complications.

A new case of analbuminemia is described for a six month old child of Algerian origin. The serum albumin concentration was 64 mg/l and its immunochemical action was identical to that of normal albumin. The system reacted by an increase of the synthesis of globulins. For the subject, the alpha1-antitrypsin, ceruloplasmin, haptoglobin, alpha2-macroglobulin, transferrin and immunoglobulins M contents were three times higher than the standard figures. However, it was possible to show that the presence of free bilirubin independent from proteins could be detected at a concentration of 17 mumol/l.

All seven pure yolk sac tumors of gonadal and extragonadal origin tested showed a bright positive fluorescence for alpha-fetoprotein in the tumor tissue. A positive reaction was seen in both the tumor cells and the hyaline globules. In all cases, however, the positive fluorescence was distributed in some focal areas of the tumor tissue. Certain tumor cells showed a strong granular intracytoplasmic fluorescence, whereas others showed a weak or a negative fluorescence. The fluorescence-positive tumor cells were located mainly in the areas rich in fluorescence-positive hyaline globules. Besides alpha-fetoprotein, certain plasma proteins--albumin, alpha-1 antitrypsin, and transferrin--were also demonstrated in all five yolk sac tumors tested. The pattern of the distribution of positive fluorescence was basically similar to that of alpha-fetroprotein. Other plasma proteins--orosomucoid, haptoglobin, Gc-globulin, alpha-2 macroglobulin, hemopexin, and ceruloplasmin--were present in certain tumors, and were distributed mainly in a limited number of hyaline globules. Both IgG and IgA were present in two tumors of ovarian origin. The immunoglobulins were for the most part present in extracellular hyaline globules, suggesting that these are taken up from the circulation. Test for fibrinogen, beta-lipoprotein, IgM, IgE, beta-1C/beta-1A and beta-1E globulins were negative or questionable. In a hepatoblastoma, tests for alpha-fetoprotein were positive, but those for other plasma proteins were negative. Fine granular fluorescence was seen in each hepatocellular tumor cell. Mesenchymal elements were virtually unstained.

Gene frequencies of the serum proteins third component of complement (C3) transferrin (Tf), haptoglobin (Hp), group specific component (Gc), serum cholinesterase (E1), alpha1-antitrypsin (Pi), beta2-glycoprotein I (Bg), and ceruloplasmin (Cp) in the Tajiks, Pushtoons, Hazaras, and Usbeks in Afghanistan were reported. Rare variants were observed in the C3, Tf, and Pi systems.

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.

The authors have elaborated a biochemical technique for the assessment of the selectivity of proteinuria by means of the clearances of ceruloplasmin, haptoglobin and albumin. The results obtained in 69 patients were compared to those established by the method of Cameron and Blanford, as well as by the clearance of alpha2-macroglobulin. No significant differences were found in the indices of proteinuria, as determined by the proposed biochemical technique and by the method of Cameron and Blanford. Thus the diagnostic value of both methods to assess the selectivity of proteinuria could be considered as equal. The additional measurement of the selectivity of proteinuria by means of proteins with considerably high molecular weight (haptoglobin, alpha2-macroglobulin) gave the possibility of recording cases with severely impaired glomerular permeability. In this respect, the use of the clearance of haptoglobulin, particularly the phenotype Hp 2--2, provided valuable diagnostic information in cases in which the routine methods gave borderline values for the index of proteinuria.

In thirty children hospitalized with acute benign, short-duration gastroenterocolitis, no obligate pathogens were isolated from stools. Five bleedings were established from each patient in order to obtain the protein profiles of albumin, orosomucoid, haptoglobin, alpha2-macroglobulin, ceruloplasmin, transferrin, C3-component, C-reactive protein, immunglobulins IgG, IgA, IgM and IgD. The proteins were quantitated by the single radial immunodiffusion method. The initial drop in some of the proteins followed may be related to general protein loss, negative nitrogen balance or hemodilution. The absence of a significant increase in all the investigated immunoglobulin classes contrasted with remarkable increase in haptoglobin and orosomucoid, both reaching normal levels in late convalescence. C-reactive protein could be demonstrated in half of the children showing early normalization with disappearance of clinical symptoms. In contrast to ceruloplasmin and C3- component, alpha2-macroglobulin was not involved in the acute phase protein reaction.

The acute phase protein response was studied after elective surgery in 13 normal subjects and 9 patients with severe chronic renal failure. Total haemolytic complement reactivity (CH50) and serum concentrations of C1q, C1s, C4, C3, factor B, properdin, C5, C9, C-reactive protein (CRP), caeruloplasmin, alpha1-acid glycoprotein and haptoglobin were measured preoperatively and on days 2, 4 and 6 after operation. Abnormalities were seen in the group with chronic renal failure. Firstly, there was no significant acute phase response of C1s, C3, C5, C9 and CH50 and a significant reduction in the response of factor B. Secondly, CRP showed prolonged elevation in the post-operative period in contrast to the transient rise seen in the control group. With the possible exception of alpha1-acid glycoprotein, the behaviour of the non-complement proteins (caeruloplasmin and haptoglobin) was comparable for the two groups. These defects could impair the physiological response to infection in patients with severe chronic renal failure.

Squirrel monkeys were inoculated by the intratracheal inoculation of 700 Klebsiella pneumoniae organisms and developed lobar pneumonia in about 24 h. Characteristic clinical findings were fever, anorexia, and coughing. Laboratory findings included leukocytosis or leukopenia (with the latter more prominent in ultimately fatal infections), bacteremia, and shedding of bacteria into the pharynx. Infected monkeys showed increased plasma lysozyme activity as well as increased plasma ceruloplasmin, haptoglobin and alpha1-antitrypsin. The mortality rate was 60%, and the mean time of death was 50.5 h. Pathologically, the disease spread by means of Kohn's pores and other pathways that generally did not involve airways as a means of dissemination until about 30 h. Squirrel monkeys seem to be better models for human respiratory K. pneumoniae infection than rats or mice.
