    The Host Component of the Popliteal Lymph Node Graft-versus-Host Reaction (1986)

    Notes: We have examined the cellular changes taking place in rat popliteal lymph nodes undergoing a graft-versus-host (GvH) reaction. Lamination of immunoperoxidase-stain lymph node sections, using a panel of mouse monoclonal antibodies directed against different rat lymphoid cell subsets, revealed a disorganization of the lymph node architecture with disappearance of the follicles, and an intermingling of T and B cells, so that no distinct T - and B-cell areas were visible any more. Since the GvH nodes showed a preferential accumulation of host B cells over host T cells (particularly over the W 3/25’T helper cell subset), we also investigated the requirements for host B cell activation. The popliteal lymph node GvH reaction was induced in (PVG x DA)F1 rats by the injection of PVG cells into one foot and by DA cells into the other foot, and then immunoglobulin kappa allotype marked PVG B cells from athymic donors were injected intravenously. The allotype marked B cells proliferated vigorously in response to the DAT cells, but much less in response to the PVG T cells. These results indicate that the massive B-cell activation taking place in GvH reactions may require an alloantigen incompatibility between donor T cells and host B cells, and argue against non-specific mitogenic induction of the B cells.

    Melanotic ganglioglioma of the pineal region (1989)

    Notes: Summary A melanotic ganglioglioma was biopsied in the pineal region of a 12-month-old girl who preoperatively underwent a ventriculo-peritoneal shunt for hydrocephalus and postoperatively received radiotherapy. The tumor was subtotally excised when the girl was 7 years and 4 months of age. Histologically, it demonstrated mature neurons in disorganized clusters and in well-differentiated cerebrum-like tissue, rare binucleated neurons, glia similar to normal gray matter, and bands of fibrous tissue containing heavily pigmented cells. Ultrastructurally, melanosomes of stages I to IV were identified in the pigmented cells. An origin involving retinal differentiation of the primitive pineal gland was not supported; the tumor was negative for both retinal S-antigen (MAbA9-C6) and cellular retinal-binding protein (CRALBP). This report demonstrates the ability of a cerebral neoplasm to contain neurons, glia, and melanin-containing cells; all of which are neuroectodermally derived.

    Severe illness caused by the products of bacterial metabolism in a child with a short gut (1985)

    Notes: Abstract An 8-year-old boy with a short gut had six episodes of metabolic acidosis and neurological dysfunction over a 1 month period. The neurological features consisted of a depressed conscious state, confusion, aggressive behaviour, slurred speech and ataxia. The organic acid profile of urine demonstrated increased amounts of lactic, 3-hydroxypropionic, 3-hydroxyisobutyric, 2-hydroxyisocaproic, phenyllactic, 4-hydroxyphenylacetic and 4-hydroxyphenyllactic acids. Of the lactic acid 99% was d-lactic acid. The anaerobic gut flora consisted almost entirely of Lactobacilli in unusually large numbers. A course of vancomycin prevented further episodes. A urinary organic acid profile may be diagnostic when a person with a short gut develops metabolic acidosis or an unusual encephalopathy and bacterial metabolites should be considered in other patients with unusual combinations of organic acids in the urine.

    Profound neurological illness, relieved by protein restriction, in a baby with a transient disturbance in the metabolism of ingested isoleucine (1987)

    Notes: Abstract An 8-month-old infant presented because of poor development followed by the acute onset of cortical blindness and a severe seizure disorder at the time of changing from breast to formula feeding. Metabolic investigations revealed an increased urinary excretion of 2-methyl-3-hydroxybutyric, methylmalonic and 2-ethylhydracrylic acids. The concentration of these compounds in urine was augmented by oral protein (5g/kg per day) and isoleucine loading. A low protein diet (1.5g/kg per day) produced a dramatic response with complete cessation of seizures and a marked improvement in vision and general development. After many months of low protein diet, the biochemical abnormalities were no longer detectable, even after protein loading. Extensive investigations have failed to reveal an intrinsic enzyme defect which would account for these clinical and biochemical findings. A toxic effect of a bacterial metabolite of isoleucine is proposed.

    The influence of a decrease in irradiance on photosynthetic carbon assimilation in leaves of Spinacia oleracea L. (1986)

    Keywords: Carbon dioxide assimilation ; Light and carbon assimilation ; Spinacia (photosynthesis) ; Sucrose synthesis

    Topics: Biology
    Notes: Abstract When leaves of Spinacia oleracea L. were subjected to a decrease from a saturating to a limiting irradiance, photosynthetic carbon assimilation exhibited a pronounced lag. This comprised a postlower-illumination CO2 burst (Vines et al. 1982, Plant Physiol. 70, 629–631) and a slow increase in the rate of carbon assimilation to the new lower steady-state rate. The latter phenomenon was distinguishable from the former because it was present in leaves when photorespiration was inhibited by high concentrations of CO2 or by 2% O2. A lag which followed a decrease in irradiance was also evident in leaves of Zea mays in air or in isolated spinach protoplasts photosynthesising in high CO2. The lag was not stomatal in origin. The origin of the lag which followed the decrease in irradiance was investigated. Measurements of total 14CO2 fixation and 14C incorporated into sucrose during the transition in irradiance showed that sucrose synthesis displayed an overshoot during the transient which accounted for all of the carbon fixed during the first 90 s of the transition period. The behaviour of hexose phosphates in the intact leaf and in the cytosol was inconsistent with their supporting sucrose synthesis during the transient. It is concluded that the overshoot in sucrose synthesis imposes a drain on chloroplast intermediates which contributes to the temporary lag in the rate of carbon assimilation.

    Hyperammonaemia and lactic acidosis in a patient with pyruvate dehydrogenase deficiency (1987)

    Notes: Summary A patient who presented in the newborn period with severe lactic acidosis and hyperammonaemia has been shown to have a specific defect in the pyruvate dehydrogenase complex. The secondary inhibition of ureagenesis in this patient appears to be due to a functional deficiency of carbamyl phosphate synthetase.
