    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Propranolol, a beta-adrenoceptor blocking drug, was administered to 6 healthy pregnant volunteers between 32 and 36 weeks gestation and when at least 6 weeks postparum. On both occasions, subjects were given propranolol 120 mg orally or 10 mg intravenously in randomised order with a minimum washout period of 1 week. Propranolol was assayed in plasma by gas-liquid chromatography with electron-capture detection and the pharmacokinetic parameters were investigated. There were no significant alterations in elimination half-life, clearance or apparent volume of distribution per kilogram antenatally compared with postnatally: bioavailability was also unchanged. It is concluded that the disposition of propranolol is not altered during pregnancy.

    Intrapatient variation in tobramycin kinetics in low birth weight infants during first postnatal week (1984)
    Springer
    European journal of clinical pharmacology 26 (1984), S. 647-649

    ISSN: 1432-1041
    Keywords: tobramycin ; newborn infants ; intrapatient variations ; pharmacokinetics

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Nineteen newborn infants receiving tobramycin, 2.5 mg/kg every 12 h were studied on two occasions at steady-state during the first week of postnatal age. The two studies were separated by two to four days. Total body clearance of tobramycin averaged 1.15 and 1.14 ml/min/kg (p〉0.05), apparent volume of distribution averaged 0.82 and 0.68 l/kg (p〉0.05), and elimination half-life averaged 8.6 and 7.1 h (p〉0.05), during the first and second study, respectively. When the data were further analyzed based on the birth weight, tobramycin kinetics changed during the second study compared to the first study in very low birth weight infants. In eight infants ⩽1.5 kg birth weight, although total clearance of tobramycin was similar, the average apparent volume of distribution decreased from 1.04 l/kg during the first study to 0.73 l/kg during the second study (p〈0.05) and elimination half-life from 11.1 h during the first study to 8.7 h during the second study (p〈0.05). These data indicate that these infants may require a change in dosing interval with continued tobramycin therapy during the first week of postnatal age. Intrapatient variation in tobramycin kinetics should be considered, in addition to the interpatient variation reported previously, when monitoring the serum concentration to individualize tobramycin therapy in newborn infants ⩽1.5 kg birth weight.

    Acetaminophen accumulation in pediatric patients after repeated therapeutic doses (1984)
    Springer
    European journal of clinical pharmacology 27 (1984), S. 57-59

    ISSN: 1432-1041
    Keywords: acetaminophen ; pediatric patients ; fever therapy ; accumulation ; pharmacokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Acetaminophen serum concentrations were studied in 21 infants and children with fever. The maximum serum concentrations ranged from 9.96 to 19.6 µg/ml after a single dose of 12–14 mg/kg and 13.9 to 40.1 µg/ml after a single dose of 22–27 mg/kg. Ten patients were restudied at steadystate after repeat doses had been given every 4 or 8 h for 1 to 3 days. Total area under the acetaminophen serum concentration-time curve normalized for dose averaged 0.181 (ml/min/kg)−1 after the first dose and 0.202 (ml/min/kg)−1 at steady-state (p〈0.05). Five patients showed a 13 to 44% increase in the AUC; one had a 10% decrease in the AUC; and four had less than 6% change in the AUC. There was no evidence of hepatotoxicity. These data suggest that acetaminophen may accumulate after repeated therapeutic doses in children with fever.

    Pharmacokinetic and pharmacodynamic study of the combination of furosemide retard and triamterene (1984)

    Keywords: furosemide ; triamterene ; drug combination ; pharmacodynamics ; pharmacokinetics ; furosemide retard ; triamterene metabolite ; urine potassium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The pharmacodynamics and pharmacokinetics of the combination of furosemide retard (30 mg)/triamterene (50 mg) were compared with furosemide (30 mg) in 18 healthy male volunteers aged 39.3±6.3 years. After the administration of furosemide the onset of its effect was very rapid, reaching a maximum between 1.5 to 3 h, and followed by rebound after 9 to 10.5 h. In contrast the combination furosemide retard/triamterene showed a protracted course with a duration of effect up to 12 h. The general effect over 12 h of the two preparations was equivalent with respect to the excretion of urine, sodium, chloride and calcium, but the combination caused significantly less excretion of potassium (p≤0.05) than furosemide. After a lag-phase of 33.9±5.4 min the maximum plasma concentration of furosemide was reached after 3.47±0.66 h, and the elimination half-life was approximately 2 h. After a lag-phase of 33.0±17.8 min the maximum plasma concentration of the main metabolite of triamterene, the OH-TA sulphuric acid ester, was reached after 1.7±0.59 h, and its elimination half-life amounted to 1.25±0.37 h. Because of the sustained release of furosemide from the retard-formulation, its principal pharmacokinetic parameters were better adapted to those of triamterene. The consequences were not only a protracted effect but also an improved electrolyte profile, especially with regard to reduced loss of potassium. In the case of renal insufficiency, however, the potassium level in serum might be increased to an undesirable extent.

    A new type D retrovirus isolated from macaques with an immunodeficiency syndrome (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-02-10
    Description: Macaque monkeys with the recently described acquired immunodeficiency syndrome show a marked defect in T-lymphocyte function and die with opportunistic infections and lymphoproliferative abnormalities. In the study described here a new type D retrovirus was isolated from two Macaca cyclopis with this syndrome. This virus is related to, but distinct from, Mason-Pfizer monkey virus, a type D retrovirus previously isolated from a mammary tumor of a rhesus monkey (Macaca mulatta).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Daniel, M D -- King, N W -- Letvin, N L -- Hunt, R D -- Sehgal, P K -- Desrosiers, R C -- R01-A1 20729/PHS HHS/ -- RR00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Feb 10;223(4636):602-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6695172" target="_blank"〉PubMed〈/a〉

    Structure of the gene encoding the immunodominant surface antigen on the sporozoite of the human malaria parasite Plasmodium falciparum (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-08-10
    Description: The gene for the circumsporozoite (CS) protein of Plasmodium falciparum has been cloned and its nucleotide sequence determined. The gene encodes a protein of 412 amino acids as deduced from the nucleotide sequence. The protein contains 41 tandem repeats of a tetrapeptide, 37 of which are Asn-Ala-Asn-Pro and four of which are Asn-Val-Asp-Pro. Monoclonal antibodies against the CS protein of Plasmodium falciparum were inhibited from binding to the protein by synthetic peptides of the repeat sequence. The CS protein of Plasmodium falciparum and the CS protein of a simian malaria parasite, Plasmodium knowlesi, have two regions of homology, one of which is present on either side of the repeat. One region contains 12 of 13 identical amino acids. Within the nucleotide sequence of this region, 25 of 27 nucleotides are conserved. The conservation of these regions in parasites widely separated in evolution suggests that they may have a function such as binding to liver cells and may represent an invariant target for immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dame, J B -- Williams, J L -- McCutchan, T F -- Weber, J L -- Wirtz, R A -- Hockmeyer, W T -- Maloy, W L -- Haynes, J D -- Schneider, I -- Roberts, D -- New York, N.Y. -- Science. 1984 Aug 10;225(4662):593-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6204383" target="_blank"〉PubMed〈/a〉

    Interferon-beta-related DNA is dispersed in the human genome (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-03-23
    Description: Interferon-beta 1 (IFN-beta 1) complementary DNA was used as a hybridization probe to isolate human genomic DNA clones lambda B3 and lambda B4 from a human genomic DNA library. Blot-hybridization procedures and partial nucleotide sequencing revealed that lambda B3 is related to IFN-beta 1 (and more distantly to IFN-alpha 1). Analyses of DNA obtained from a panel of human-rodent somatic cell hybrids that were probed with DNA derived from lambda B3 showed that lambda B3 is on human chromosome 2. Similar experiments indicated that lambda B4 is not on human chromosomes 2, 5, or 9. The finding that DNA related to the IFN-beta 1 gene (and IFN-alpha 1 gene) is dispersed in the human genome raises new questions about the origins of the interferon genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sagar, A D -- Sehgal, P B -- May, L T -- Inouye, M -- Slate, D L -- Shulman, L -- Ruddle, F H -- AI-16262/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Mar 23;223(4642):1312-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6546621" target="_blank"〉PubMed〈/a〉

    A replication cycle for viroids and other small infectious RNA's (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-02-03
    Description: Experimental data concerning viroid-specific nucleic acids accumulating in tomato plants establish, together with earlier studies, the major features of a replication cycle for viroid RNA in plant cells. Many features of this pathway, which involves multimeric strands of both polarities, may be shared by other small infectious RNA's including certain satellite RNA's and "virusoid" RNA's which replicate in conjunction with conventional plant viruses. The presence, in host plans, of an elaborate machinery for replicating these disease agents suggests a role for endogenous small RNA's in cellular development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Branch, A D -- Robertson, H D -- New York, N.Y. -- Science. 1984 Feb 3;223(4635):450-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6197756" target="_blank"〉PubMed〈/a〉

    Structure of 3' terminal region of type II human T lymphotropic virus: evidence for new coding region (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-07-27
    Description: The sequence of the 3' terminus of the human T lymphotropic virus type II (HTLV-II) was determined and compared to the corresponding sequence of HTLV-I. The 1557-nucleotide-long sequence can be divided into a 5' region that is not conserved between the two viruses, and a 3', 1011-nucleotide-long region that is highly conserved and that corresponds precisely with a long open reading frame for both HTLV-I and -II. The proteins that could be encoded by these open reading frames have a molecular weight of about 38,000 and are closely related in primary amino acid sequence. The genomic structure in the 3' region of HTLV was found to be similar to that of bovine leukemia virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haseltine, W A -- Sodroski, J -- Patarca, R -- Briggs, D -- Perkins, D -- Wong-Staal, F -- CA07094/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Jul 27;225(4660):419-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6330894" target="_blank"〉PubMed〈/a〉
