prenatal methylmercury poisoning. clinical observations over five years.thirty-two infants prenatally exposed to methylmercury and their mothers were examined over a five-year period after the iraqi methylmercury epidemic. severity of poisoning in mothers was related to the peak mercury concentration in their hair and in the infants to the maximum concentration in maternal hair during pregnancy. in nine cases of cerebral palsy, methylmercury exposure occurred only during the last trimester. all infants except three (two were orphaned soon after birth and one was bot ...199984530
thyrotoxicosis during pregnancy.the diagnosis of thyrotoxicosis during pregnancy is difficult on clinical grounds only. the determination of free thyroid hormones or free thyroid hormone indices is important and is possibly supplemented by the trh stimulation test. thyrotoxicosis during pregnancy should always be treated actively. the authors recommend subtotal thyroidectomy if there are indications for surgical therapy (nodular goitre or large diffuse goitre). otherwise treatment with thyrostatic agents is used. after operati ...199984547
observations on the m-wave and the cnv in the squirrel monkey.a typical cnv paradigm, with food as reward, evokes in the squirrel monkey's post-arcuate and post-central cortices both m-waves in response to the cues and what appears to be a cnv in the interstimulus interval. both wave forms appear to be generated locally in cortex and to be more closely related temporally to the cues than to the animal's behavioral response. the cnv, like the m-wave, appears to reflect the animal's level of interest in obtaining the reward. it is smaller when the animal mis ...197985525

antiviral agents: action and clinical use.the development of antiviral agents has been hindered by a variety of problems. there are fundamental biological differences between viruses and other infectious agents. viruses are strictly dependent on cellular metabolic processes and possess very limited intrinsic enzyme systems and building blocks which may serve as targets for drugs. antiviral drugs must also possess the ability to enter the host cell. viral replication consists of a series of events, each of which can be interfered with, l ...197992398
nonspecific light loss and intrinsic dna variation problems associated with feulgen dna cytophotometry.nonspecific light loss by the cell-wall-plus-cytoplasm (cwc) can cause a 50% increase in feulgen absorption units in peanut root-tip nuclei as determined by scanning at 450 nm, whereas this phenomenon is not evident with chicken erythrocytes. a two wavelength scanning method of subtracting nonspecific 450 nm absorption from 550 nm feulgen absorption values eliminated the nonspecific light loss in cwc, however, the two wavelength scanning method is time consuming and somewhat impractical with a r ...197992496

preliminary experience with the helifix electrode for transvenous atrial implantation.a helifix electrode was inserted transvenously in the right atrial appendage for temporary atrial stimulation in three patients. the low stimulation threshold as well as the excellent stability of the electrode encouraged us to proceed to permanent implantation of this lead in thirteen patients. the lead was introduced through the saphenous vein in twelve patients and through the cephalic vein in one patient. five patients had sinoatrial dysfunction and five had bradycardia-tachycardia syndrome; ...200195313
lower levels of thyrotropin-releasing hormone-degrading activity in human cord and in maternal sera than in the serum of euthyroid, nonpregnant adults.thyrotropin-releasing hormone (trh)-degrading activity was investigated in human cord, maternal, and euthyroid adult sera by measuring (a) the rate of disappearance of trh and (b) the rate of formation of degradation products. the rate of trh degradation in cord and maternal sera was 25-33% of that in euthyroid adult serum. concomitantly, in cord and maternal sera, the rate of formation of proline, a major trh degradation product in serum, was one-quarter to one-third that in euthyroid adult ser ...197896140
cellular changes in the toad urinary bladder in response to metabolic acidosis.the urinary bladder of bufo marinus excretes h+ and nh+4, and the h+ excretion is increased when the animal is placed in metabolic acidosis. the mitochondria-rich (mr) cells mediate the h+ excretion by the bladder. the purpose of this study was to determine if there is a change in mr cells of the bladder during metabolic acidosis. bladders from normal toads and from toads that had been placed in metabolic acidosis were used. the bladders were mounted between plastic chambers and h+ excretion mea ...199996269
diminished cellular immunity due to impaired nutrition in oesophageal carcinoma.the nutritional status of 15 negro patients suffering from unresectable carcinoma of the midthoracic oesophagus was evaluated before and after palliative pulsion intubation. all were shown to be in negative nitrogen balance and to have a compromised non-specific cellular immune response. correction of protein-calorie malnutrition and the achievement of positive nitrogen balance were associated with an increase in absolute lymphocyte and t lymphocyte numbers and a significant increase in lymphocy ...199996903
long term effects of myochrysine in articular cartilage.intra-articularly administered sodium aurothiomalate (myochrysine) produced aurosomes containing characteristic electron dense contents (indicating the presence of gold), in the chondrocytes of rabbit articular cartilage. at first the aurosomes were bounded by a membrane but later the electron dense contents were seen lying free in the cytoplasmic matrix. such deposits were detectable up to 14 months after injection of myochrysine but none were found at later time intervals (18 months and 2 year ...197897856
