Abstract
Abstract
The Bordetella pertussis endotoxin, labeled with tritium ((3H)-LPS), bound irreversibly and nonspecifically to rabbit lung macrophages, but bound reversibly and specifically to both resident and elicited rabbit peritoneal macrophages. The specific binding capacity of the macrophages was saturated with about 3 X 10(4) LPS molecules per cell. The binding was inhibited with the homologous unlabeled endotoxin, but not at all with endotoxin from Proteus mirabilis, thus assessing ligand specificity. Endotoxins from other bacteria gave intermediate inhibition value. Binding of tritium-labeled pertussis endotoxin was significantly inhibited by one of the two polysaccharides (PS-1) present in this endotoxin, but neither the other polysaccharide (PS-2) nor the Lipid A fragment exhibited such activity. These results strongly suggest the presence of a lectin-like receptor for LPS on the membrane of rabbit peritoneal macrophages.

Abstract
The lipid peroxidation and (of the peroxide metabolism enzymes) the catalase, superoxide dismutase and glutathione peroxidase activities were determined in red blood cell haemolysates from 20-35-year-old human diabetics of both sexes. The results were compared with the values for normal controls from the same age group. The diabetic haemolysates displayed significantly higher glutathione peroxidase and significantly lower superoxide dismutase activities. The lipid peroxidation too was significantly higher in the diabetic haemolysates. Diabetes was induced with alloxan or streptozotocin in rats, and the enzyme activities of the blood and organ homogenates were similarly compared; in these cases the total peroxidase activity. In experimental diabetes the previously-observed phenomenon of oxidative stress was confirmed; this may serve as a logical explanation for the occurrence of the later diabetic damage.

Abstract
1. Guinea-pigs, which exhibit a similar metabolism to that of man insofar as they are incapable of synthesizing ascorbic acid, were poisoned with Gramoxon containing the LD50 or LD100 of paraquat. 2. A study was made of how the paraquat poisoning affected previously investigated tissue parameters, the superoxide dismutase, catalase and glutathione peroxidase activities and the lipid peroxidation. 3. In accordance with earlier results, the paraquat influences these parameters in different ways in all the tissues examined, depending on its concentration. 4. These parameters comprise primarily affected systems as regards paraquat toxicity.

Abstract
1. Substances previously tested therapeutically were studied to obtain evidence on the pathomechanism in mice of paraquat, the active ingredient of Gramoxon, connected with the radicals formed from molecular oxygen, and also to extend the therapeutic possibilities. 2. The effects of these substances were assessed on the basis of the 72-hr survival rate and the percentage ratio of the wet lung weight to the overall body weight. 3. Other toxicological parameters too were followed. 4. Our present investigations indicate that, in agreement with our earlier results, besides reduced glutathione and ascorbic acid, vitamin E and C-ase are of the greatest importance from the aspect of the protection against paraquat toxicity. 5. In addition to those listed, other materials too, e.g. antifibrotic substances, naturally possess considerable detoxicating properties too.

Abstract
In the liver of neonate rats and in tissues of adult rats a study was made of the effect of D-penicillamine treatment in vivo on the enzymes of peroxide metabolism, lipid peroxidation and other components. It was found that D-penicillamine primarily acts by decreasing lipid peroxidation, thus stabilizing the membrane.

Abstract
Endotoxin prepared from several Bordetella pertussis strains in both immunological phases I and IV gave two lipopolysaccharide peaks (LPS-I and LPS-II) when analyzed on hydroxylapatite columns in a phosphate buffer containing 0.1% sodium dodecyl sulfate; these lipopolysaccharides, present in the ratio of 2:3, are true endotoxins by both chemical and biological criteria. Endotoxins isolated from Escherichia coli, Salmonella typhimurium, and Shigella flexneri gave single lipopolysaccharide peaks when analyzed by the same procedure. Upon hydrolysis with acetic acid (pH 3.4) at 100 degrees C for 1 h, LPS-I released a polysaccharide (PS-I); the linkage broken was that of the glycosidic bond of a non-phosphorylated 3-deoxy-oct-2-ulosonic acid. Treatment with 0.25 M mineral acid at 100 degrees C for 30 min was required to free the polysaccharide moiety (PS-II) of LPS-II, the linkage broken being the glycosidic bond of a phosphorylated 3-deoxy-oct-2-ulosonic acid. Chemical and physical differences of the polysaccharide moieties PS-I and PS-II present in LPS-I and LPS-II have been described previously (25). By using the technique of 125I labeling, it was shown that the totality of labeled proteins present in the endotoxin extracted from Bordetella pertussis by the phenol-water procedure could be separated from the lipopolysaccharide by column chromatography on hydroxylapatite; it follows that these proteins are not linked by covalent bonds to the lipopolysaccharide.

Abstract
Three oligosaccharide alditols, a di (44-63%), tetra (32-46%), and a pentasacchariditol (5-10%) have been isolated from desialylated caseinomacropeptide obtained from kappa-casein of ewe colostrum. The disacchariditol is 2-acetamido-2-deoxy-3-O-(beta-D-galactopyranosyl)galactitol; in the tetrasaccharide this unit is substituted in position 6 of the galactosaminitol moiety by 2-acetamido-2-deoxy-4-O-(beta-D-galactopyranosyl)-beta-D-glucopyranose, while the pentasacchariditol is derived from the tetrasaccharide by addition of a D-galactopyranosyl unit to position 3 of the galactopyranose unit substituting the glucosamine unit.

Abstract
Six children in an inbred isolate (a gypsy colony) were found to have a syndrome of reduplication of the big toes, supernumerary fingers on the hands, cleft lip/palate or lingual nodule, and somatic and psychomotor retardation. Other features sometimes present were absence of olfactory bulbs and tracts, cryptorchidism, inguinal hernia, and congenital heart disease. The disorder has overlapping features with several previously delineated syndromes, but is most similar to the anomalies of trisomy 13 Mand ohr's syndrome. Our patients had a normal karyotype. The mode of inheritance of this lethal genetic syndrome is probably autosomal recessive.

Abstract
A family of ten members in three generations who were affected by lymphoedema with or without distichiasis (extra rows of eyelashes) was observed. This combination of symptoms can be presumed to represent a rare but well-defined hereditary syndrome transmitted by an autosomal dominant gene. Some years ago the published pedigrees of congenital hereditary lymphoedema were reviewed and analysed genetically by Esterly (1965). Recently papers have been published on the association of lymphostasis with congenital distichiasis (Falls and Kertesz, 1964; Robinow et al., 1970; Jester, 1977). We report here a family with ten members in three generations affected by lymphoedema with or without distichiasis.

Abstract
Endotoxin from fresly sedimented Bordetella pertussis cells, isolated by the phenol/water procedure when submitted to kinetically controlled, mild acidic hydrolysis released a polysaccharide (polysaccharide 1), a complex lipid (lipid X), and a glycolipid. When treated with somewhat stronger acid, the glycolipid yielded a second polysaccharide (polysaccharide 2) and another complex lipid (lipid A). The intact pertussis endotoxin had all the usual properties of endotoxins extracted from enteric bacteria. Lipid X and the intermediary glycolipid retained all the endotoxic properties of the unfractionated endotoxin. In lipid A, pyrogenicity was reduced to a very low level and toxicity and Shwartzman reactivity were absent; however, this fraction retained most of the endotoxin's antiviral activity, and its adjuvant power was considerably higher than that of the intact endotoxin. Lipid A elicited nonspecific resistance against challenge with certain bacteria, but not against others.

Abstract
Fibroblasts from a patient with mannosidosis were grown in a medium containing a radioactive monosaccharide (D-[U-14C]mannose or N-acetyl-D-[1-14C]-glucosamine). An accumulation of radioactive material was observed. It was possible to prevent the accumulation to a certain degree by the addition of human liver alpha-D-mannosidase to the fibroblast medium. After six days of fibroblast culture the majority of the accumulated material had a molecular weight in the oligosaccharide range and was stationary during high-voltage electrophoresis. Paper chromatography of the stationary material separated three radioactive compounds with the same chromatographic mobilities as the oligosaccharides alpha-D-Man-(1 leads to 3)-beta-D-Man-(1 leads to 4)-D-GlcNAc (I), alpha-D-Man-(1 leads to 2)-alpha-D-Man-(1 leads to 3)-beta-D-Man-(1 leads to 4)-GlcNAc (II), and alpha-D-Man-(1 leads to 2)-alpha-D-Man-(1 leads to 2)-alpha-D-Man-(1 leads to 3)-beta-D-Man-(1 leads to 4)-GlcNAc (III) previously isolated from the urine of patients with mannosidosis. Degradation of the three radioactive compounds with jack bean alpha-mannosidase gave D-mannose and a disaccharide (containing D-mannose and N-acetyl-D-glucosamine). Thus the three main compounts observed in the fibroblasts from patients with mannosidosis are most probably identical to the oligosaccharides I--III.
