immunocytochemical characterization of the lymphocytes in nodular lymphoid hyperplasia of the bowel.the immunoglobulin constituents of hypertrophied lymphoid nodules in the intestinal tracts of six patients with the variable immunodeficiency syndrome and one patient with selective iga deficiency were evaluated by the peroxidase-labeled antibody technique. the nodules were found to contain a dense population of igm-bearing lymphocytes and much intercellular igm. evidence that the cells were engaged in igm synthesis was the presence of the immunoglobulin in the perinuclear spaces and endoplasmic ...1998105208
case report: intestinal clearance of calcium and protein in waldenstrom's macroglobulinemia.a 63-year-old man with waldenstrom's macroglobulinemia had severe steatorrhea, marked protein-losing enteropathy, and excessive endogenous fecal calcium clearance. the malabsorption and protein loss resulted in weight loss and hypoalbuminemia. in contrast, the striking enteric calcium loss was completely compensated by an increase in calcium absorption resulting in a positive calcium balance.1978105640
[stimulation with automatic radiofrequency scanning in the long term treatment of tachyarrythmias].a pacemaker is described which uses radiofrequency signals for synchronisation and pacing, and seeks automatically the phase of the cycle at which the tachycardia may be interrupted. the patient himself can activate the pacemaker. the programme of the external transmitter, which scans nearly all the r-r cycles of the tachycardia, may be pre-set to transmit one or two synchronised stimuli, with a progressive delay of 5 or 10 ms. if the tachycardia is interrupted the pacing stops automatically. th ...1998105682
fetal heart rate during a maternal grand mal epileptic seizure.although maternal ingestion of antiepileptic drugs is strongly suspected of causing congenital defects, particularly oral clefts, the effect of epilepsy itself or a combined effect of drug intake and epilepsy have not been excluded as etiological factors. very little is known about fetal oxygenation during a maternal grand mal epileptic seizure. we describe two cases in which fetal heart rate was recorded during a maternal epileptic seizure during labor. the first fetus became clearly asphyctic ...1998106102
polychlorinated biphenyl-induced morphologic changes in the gastric mucosa of the rhesus monkey.the early morphologic events in polychlorinated biphenyl-induced lesions of the gastric mucosa of immature male rhesus monkeys (macaca mulatta) were studied in serial biopsies taken during consumption of diets containing 3, 10, 30, and 100 mg. per kg. (p.p.m.) of aroclor 1242. the severity of the lesions correlated directly with both the duration and the level of exposure. the first changes were seen after ingestion of 30 and 100 mg. per kg. for 2 weeks; changes were not seen until 10 weeks at 3 ...1979106183
catheter cervical vertebral venography.cervical vertebral venography using catheterzation via the femoral vein was carried out in 78 cases. in disc disease the internal vertebral venous plexus (ivvp) are interrupted at single or multiple levels, and sometimes completely blocked. in ossification of posterior longitudinal ligament, the ivvp are separated bilaterally and interrupted at multiple levels due to centrally situated ossification and associated osteophytes. venography helps to determine the upper and lower limits of laminectom ...1998106325

transplantation of hymenolepis diminuta into naive, immune and irradiated mice.almost 100% of 7- to 10-day-old hymenolepis diminuta became established when surgically transplanted from donor mice into the duodenum of naive recipient mice. transplanted tapeworms survived 8-12 days, by which time they had survived much longer in total than they would have done in the donor. mice previously immunized by a primary infection rejected transplants within 4 days. sub-lethal irradiation (550 rad) delayed rejection by immune mice but such mice still rejected worms much more quickly ...1976135242

suppressor mechanisms in neonatally acquired tolerance to a gross virus-induced lymphoma in rats.tolerance to a highly immunogenic gross virus-induced tumour in wistar/furth rats (c58nt)d was produced by neonatal infection of the rats with the virus. these rats failed to reject the tumours when challenged 8 weeks after virus inoculation and to mount the appropriate cell-mediated immune response to the tumour. the mechanisms involved were studied in vivo by adoptive transfers into sub-lethally irradiated rats of tumour cells mixed with spleen cells and/or sera from normal, tolerant, or tumou ...1976135385
