Purification of placental anemia inducing factor (PAIF) and its clinical application by radioimmunoassay.

Human Placental Anemia Inducing Factor (PAIF) was purified from crude placental preparation called P- 62, which had common biological and immunological natures with the same preparation from gastric juice, gastric tissues, serum and urine of patients with malignant neoplasma, especially gastric cancer. The obtained PAIF was homogeneous on polyacrylamide gel electrophoresis and gave a specific band in the region of gamma-A and/or gamma-M globulin on immunoelectrophoresis. The purified PAIF induced anemia in rabbits by intravenous administration at a dose of 2.7 micrograms/Kg of body weight. No cross antigenicity of PAIF was observed with alpha-Fetoprotein. HBs antigen and CEA. Serum AIF of patients was measured using PAIF as a standard by radioimmunoassay. AIF levels in sera of patients with malignant neoplasma were significant high compared with those of control groups.

Effect of microphase separated structure of polystyrene/polyamine graft copolymer on adhering rat platelets in vitro.

Rat platelet adhesion on microphase separated surface of polystyrene/polyamine graft copolymers (SA copolymers) was investigated. Shapes of adhering platelet were very much changeable in response to the mode of microphase separation of SA copolymer surfaces. We assume that the microphase separated structure of SA copolyer may regulate the shape change of platelet through its effect on a redistribution of proteins and/or lipids present at the plasma membrane of platelets.

Sophorolipids from Torulopsis bombicola: possible relation to alkane uptake.

Torulopsis bombicola produces extracellular sophorolipids when it is grown on water-insoluble alkanes. Sophorolipids and related model compounds, which were not themselves used for growth, were found to stimulate markedly the growth of T. bombicola on alkanes. This stimulatory effect was restricted to growth on C10 to C20 alkanes, whereas no significantly influence was observed for growth on fatty alcohols, fatty acids, glucose, or glycerol. The nonionic methyl ester of the glycolipid supported the greatest cell yield. However, a number of synthetic nonionic surfactants were unable to replace the glycolipid. When organisms were grown on hexadecane, stimulation of growth by sophorolipids was observed almost exclusively with strains of Torulopsis yeasts. In contrast, the growth of other typical alkane-utilizing yeasts, such as candida and Pichia strains, was inhibited or not affected. It appears that sophorolipids are involved in alkane dissimilation by T. bombicola through an undetermined mechanism.

Ventilatory response and drive due to carbon dioxide stimulation in idiopathic scoliosis.

Ten patients with idiopathic scoliosis and seven controls were studied for the purpose of investigating the ventilatory response and drive due to CO2 inhalation by the steady state CO2 response test. To evaluate the ventilatory drive for the respiratory output mouth occlusion pressure (P0.1) was used. The ventilatory response to CO2 of the patients was not significantly different from that of the controls. P0.1 for a given PCO2 stimulation or tidal volume in the patients was significantly higher than the control. Ventilatory output against P0.1, however, was not different in the two groups. The small tidal volume of the scoliotic patients seemed to be compensated by the high respiratory frequency with a large ventilatory drive in order to maintain adequate ventilation.

Lymphocytotoxic autoantibodies in pemphigus and systemic lupus erythematosus.

Lymphocytotoxic autoantibody (LCTA) was studied in 9 patients with active pemphigus and 19 patients with active systemic lupus erythematosus (SLE). All patients with SLE showed high titres of LCTA but only one patient with pemphigus had LCTA. In this paper we discuss the immunological significance of LCTA and the difference in the incidence of LCTA between pemphigus and SLE. In addition we present the clinical features of the case with LCTA-positive pemphigus and suggests that the presence of LCTA is due to the common viral infection.

Obesity and diabetes - a possible experimental model of maturity-onset-type diabetes.

This study aimed to acquire a possible experimental model of obese non-insulin-dependent diabetes. Around 230 g Sprague-Dawley female rats were divided into 4 gp: (1) sham ventromedial hypothalamic (VMH) lesioned rats fed low-fat diet (control rats); (2) VMH lesioned rats fed low-fat diet; (3) sham VMH lesioned rats fed high-fat diet and (4) VMH lesioned rats fed high fat diet, and they were observed for 10 weeks (Exp. 1). This experiment was repeated using rats treated by small doses of streptozotocin (5 mg/kg) (Exp. 2). Body weight was measured weekly, blood glucose, every other week and serum insulin, at the end of the experiments. VMH obese rats fed low-fat diet showed normal levels of fasting blood glucose with hyperinsulinemia. VMH obese rats fed high-fat diet showed mildly elevated levels of fasting blood glucose (155 +/- 8 mg/dl as compared to 125 +/- 3 mg/dl of controls) with hyperinsulinemia (5.92 +/- 0.61 ng/ml). Streptozotocin treated VMH obese rats fed low-fat diet did not show increasing levels of fasting blood glucose, while streptozotocin treated VMH obese rats fed high-fat diet showed marked elevation of fasting blood glucose (229 +/- 23 mg/dl). The latter group of rats also had hyperinsulinemia (3.82 +/- 0.45 ng/ml compared to 1.36 +/- 0.14 ng/ml of controls), although concentrations of serum insulin were decreased by streptozotocin treatment compared to levels of VMH obese rats fed high-fat diet. These results demonstrated that VMH obese rats fed high-fat diet showed milk hyperglycemia with hyperinsulinemia. Following treatment of small doses of streptozotocin, VMH obese rats fed high fat diet showed marked hyperglycemia with hyperinsulinemia. The profile of these rats resembles that of maturity onset-type diabetes which accompanies with obesity and hyperinsulinemia.

Increase of postheparin plasma-lipoprotein-lipase activity in ventromedial-hypothalamic obesity in rats.

Postheparin plasma-lipoprotein lipase (LPL) and hepatic triglyceride lipase (H-TGL) were investigated in rats 1 week after ventromedial-hypothalamic lesions. The enzyme activities were measured using radio-labelled triolein as a substrate. Two lipases were measured separately using specific antiserum prepared against H-TGL. VMH-lesioned rats fed ad lib. showed an increase in plasma LPL with normal H-TGL activity and an elevation of plasma insulin. There was a positive correlation between plasma-LPL activity and insulin levels in VMH-lesioned rats. When rats were examined after overnight fast, VMH-lesioned rats again showed an increase in plasma LPL with normal H-TGL activity and an elevation of plasma insulin. There was also a positive correlation between plasma LPL activity and insulin levels. In order to examine the effect of insulin, rats were treated with daily doses of 3 units of insulin for 1 week. Rats fed ad lib. were insulin treatment showed an increase in plasma LPL with normal H-TGL activity. These results indicate that hyperinsulinemia which was produced by VMH lesions may increase postheparin plasma-LPL activity. We speculate that this increase in plasma-LPL activity mainly reflects that of adipose tissue. The increase of LPL activity can accelerate fat deposition into adipose tissue, contributing to one of the factors causing hypothalamic obesity.
