Notes on the preparatio and assay of anti-lymphocyte serum for use in mice

The `activity' of rabbit anti-mouse ALS was measured in terms of its power to prolong the life of A-strain homografts on CBA mice. Antisera raised by lymphocytes from mice of other strains were active in CBA mice, and conversely antisera raised by CBA lymphocytes were active in mice of other strains. All active sera were cytotoxic to mouse lymphocytes in the presence of mouse complement, but not all cytotoxic sera were active. ALS raised in species (chicken, duck) of which the sera do not bind with mouse complement were inactive in mice. Neither cytotoxicity nor the power to circumvent graft-versus-host reactions give adequate measures of the activity of impure antisera.

Good antiserum (`two-pulse' ALS) for use in mice could be raised in New Zealand White rabbits by the intravenous injection of 10⁹ mouse thymocytes on two occasions 14 days apart, followed by bleeding out 7 days after the second injection. Further injections of antigen increased the titre of undesirable contaminants in ALS (e.g. red cell agglutinins) but usually did not increase (and sometimes lowered) activity. ALS raised with adjuvants, though powerful, was highly toxic and required extensive absorption.

     

The value of diagnostic testing in carpal tunnel syndrome.

The purpose of this study was to determine the validity of tests or a combination of tests for the diagnosis of carpal tunnel syndrome. Three groups of 50 subjects each were studied: group 1 had definite carpal tunnel syndrome as defined by history, clinical presentation, and improvement of symptoms following carpal tunnel release; group 2 had a variety of nontraumatic upper extremity disorders other than carpal tunnel syndrome; and group 3 subjects were asymptomatic healthy volunteers. Subjects submitted a self-administered hand diagram, and were queried about night pain, symptom duration, and coexistent medical conditions. Phalen's test, Tinel's sign, Durkan's compression test, and Semmes-Weinstein monofilament testing both before and after a Phalen's maneuver for 5 minutes were performed on each subject. Grip and pinch strengths were measured. Univariate analysis of groups 1 and 2 showed that the tests with the highest sensitivity were Durkan's compression test (89%), Semmes-Weinstein testing after Phalen's maneuver (83%), and hand diagram scores (76%). Night pain was a sensitive symptom predictor (96%). The most specific tests were the hand diagram (76%) and Tinel's sign (71%). Analysis of groups 1 and 3 without group 2 increased the specificity and predictive value of a positive test. A regression model was used to develop a multivariate equation with 4 variables. If a patient has an abnormal hand diagram, abnormal sensibility by Semmes-Weinstein testing in wrist-neutral position, a positive Durkan's test, and night pain, the probability that carpal tunnel syndrome will be correctly diagnosed is 0.86. If all 4 of these conditions are normal, the probability that the patient has carpal tunnel syndrome is 0.0068. We found that the addition of electrodiagnostic tests did not increase the diagnostic power of the combination of 4 clinical tests.     

The Concise Guide to Pharmacology 2013/14.: The Concise Guide to Pharmacology 2013/14: Overview

The Concise Guide to PHARMACOLOGY 2013/14 provides concise overviews of the key properties of over 2000 human drug targets with their pharmacology, plus links to an open access knowledgebase of drug targets and their ligands (www.guidetopharmacology.org), which provides more detailed views of target and ligand properties from the IUPHAR database. The full contents can be found at http://onlinelibrary.wiley.com/doi/10.1111/bph.12444/full.This compilation of the major pharmacological targets is divided into seven areas of focus: G protein-coupled receptors, ligand-gated ion channels, ion channels, catalytic receptors, nuclear hormone receptors, transporters and enzymes. These are presented with nomenclature guidance and summary information on the best available pharmacological tools, alongside key references and suggestions for further reading. A new landscape format has easy to use tables comparing related targets.It is a condensed version of material contemporary to late 2013, which is presented in greater detail and constantly updated on the website www.guidetopharmacology.org, superseding data presented in previous Guides to Receptors & Channels. It is produced in conjunction with NC-IUPHAR and provides the official IUPHAR classification and nomenclature for human drug targets, where appropriate. It consolidates information previously curated and displayed separately in IUPHAR-DB and GRAC and provides a permanent, citable, point-in-time record that will survive database updates.
