    Description / Table of Contents: Zusammenfassung Die Autoren berichtenüber die Ergebnisse von In-vitro-Untersuchungen über die Höhe der Porphobilinogen- und der Porphyrinsynthese in menschlichen Erythrozyten mit Eisenmangel. Es zeigte sich, 1. daß die Synthese von Porphobilinogen aus δ-Aminolacvulinsäure praktisch normal ist; 2. daß in Erythrozyten mit Eisenmangel die Aminolaevulinsäure dem gleichen Stoffwechselweg folgt wie in normalen roten Blutkörperchen; 3. daß die Synthese von Porphyrin aus Porphobilinogen zum Teil gehemmt und die Menge des gebildeten Porphyrins erheblich verringert ist; 4. daß die Gabe von Eisen die Höbe der Porphyrinsynthese aus Porphobilinogen normalisiert ohne die Synthese diese Pyrolls zu stören.
    Notes: Summary The results ofin vitro studies on the rate of porphobilinogen and porphyrin synthesis in iron deficient human red blood cells are reported. It was found: 1. that the synthesis of porphobilinogen from δ-aminolaevulic acid is virtually normal; 2. that in iron deficient red blood cells δ-aminolaevulic acid follows the same metabolic paths as in normal red blood cells; 3. that the synthesis of porphyrin from porphobilinogen is partly inhibited, the amount of porphyrin formed being appreciably decreased; 4. that the administration of iron normalises the rate of porphyrin synthesis from porphobilinogen without interfering with the synthesis of this pyrrole.

    Description / Table of Contents: Zusammenfassung Bei 10 gesunden Menschen und 10 Patienten mit Leberzirrhose wurde der Serumeisen-Umsatz, die Ferrokinetik im Organismus, die Hämoglobinsynthese, die Halbwertzeit der Erythrozyten und die mittlere Reifungszeit des Erythrons mit Hilfe von59Fe untersucht. Der Eisenumsatz und die Hämoglobinsynthese waren bei der Leberzirrhose zwar signifikant erhöht, jedoch nicht so ausreichend, daß dadurch die Reduktion der Erythrozytenlebensdauer kompensiert wird. Die mittlere Reifungszeit des Erythrons war normal. Nach den vorliegenden Befunden konnten zwei Faktoren für die Anämie bei Leberzirrhose verantwortlich gemacht werden: die Hämolyse und die relative Knochenmarksdepression. Mit Hilfe der angewandten Methodik war es möglich, die Rolle dieser Faktoren bei allen untersuchten Patienten quantitativ aufzudecken.
    Notes: Summary Turnover of plasma iron, kinetics of iron through the body compartements, hemoglobin synthesis, red cell half life and mean effective erythron maturation time were studied, by using Fe59, in 10 normal subjects and 10 cirrhotic patients. Iron turnover and hemoglobin synthesis were significantly raised, but not sufficiently to compensate the red cell life span reduction. Mean effective erythron maturation time was normal. In conclusion two factor were responsible for the anemia: the hemolysis and a relative marrow depression. By the method used it was possible to discriminate quantitatively their importance in all the subjects investigated.

    Description / Table of Contents: Zusammenfassung Die Ergebnisse von Untersuchungen zur Feststellung, ob die Höhe der Protoporphyrinsynthese aus δ-Aminolävulinsäure bei Eisenmangelanämie geringer ist und ob Eisen für die Synthese von Zwischenprodukten im Porphyrinstoffwechsel wesentlich ist, werden berichtet. Durch das Messen von δ-Aminolävulinsäure im Harn, Porphobilinogen-, Koproporphyrin- und Uroporphyrinausscheidung im Harn und die fäkale Ausscheidung von Koproporphyrin und Protoporphyrin wurde ein Absinken der Höhe der Porphyrinsynthese bei Fällen von idiopathischer hypochromer Anämie nachgewiesen. Der relative Anstieg in der Porphobilinogenausscheidung im Harn deutet auf eine Teilblockierung der Porphyrinsynthese von Porphobilinogen. Eisenbehandlung normalisiert den Porphyrinstoffwechsel.
    Notes: Summary The results of studies done to ascertain whether the rate of protoporphyrin synthesis from δ-aminolaevulic acid is decreased in iron deficiency anaemia and whether iron is essential for the synthesis of the intermediate compounds in the porphyrin metabolism are reported. By measuring the urinary δ-amino-laevulic acid, porphobilinogen, coproporphyrin and uroporphyrin excretion and the faecal coproporphyrin and protoporphyrin excretion a decrease in the rate of porphyrin synthesis was demonstrated in cases of idiopathic hypochromic anaemia. The relative increase in the urinary porphobilinogen excretion points to a partial block of porphyrin synthesis from porphobilinogen. Iron treatment normalises the porphyrin metabolism.

    Nerve growth factor (NGF) in cerebrospinal fluid (CSF) from patients with various neurological disorders (1994)

    Description / Table of Contents: Sommario È stato recentemente dimostrato che l'NGF non è solamente coinvolto nella sopravvivenza e lo sviluppo dei neuroni del sistema simpatico e in quelli sensitivi derivati dalla cresta neurale, ma anche in alcuni meccanismi del sistema immunitario. Per questo motivo abbiamo studiato il contenuto di NGF nel liquor di pazienti affetti da malattie quali la sclerosi multipla, la sclerosi laterale amiotrofica, la malattia di Alzheimer, le polineuropatie croniche recidivanti, la sindrome di Guillain-Barré e i tumori del sistema nervoso, nelle quali meccanismi neuroimmunologici paiono essere coinvolti, ed inoltre in un gruppo di soggetti neurologicamente sani presi come controlli. Abbiamo messo a punto una metodica ELISA per dosare la subunità beta dell'NGF, ottenendo buoni test di validazione e sensibilità fino a 28 pg βNGF per ml. Nessuno dei campioni conteneva livelli misurabili di NGF. Abbiamo quindi concentrato i campioni, ma soltanto un paziente ha presentato livelli significativi. Questo probabilmente mostra che l'NGF non è coinvolto nei meccanismi neuroimmunologici che potrebbero essere alla base di alcune malattie degenerative ed infiammatorie del sistema nervoso.
    Notes: Abstract It has been recently shown that NGF is not only involved in the survival and development of sympathetic and neural crest-derived sensory neurons, but also in some mechanisms of the immune system. For this reason, we studied the content of NGF in CSF samples from patients with diseases in which neuroimmonological mechanisms seem to be involved (multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer disease, chronic relapsing polyradiculoneuritis, Guillain-Barré syndrome, and tumors of the nervous system), as well as from a number of normal control subjects. We setup an ELISA aimed at the beta subunit of NGF, obtaining good validation tests and a detection limit of 28 pg βNGF per ml. None of the samples was found to contain detectable levels of NGF and, when a concentration method for sample enrichment was used, only one patient was NGF-positive. This suggests that NGF is probably not involved in the neuroimmunological mechanisms underlying some inflammatory and degenerative diseases of the nervous system.

    Description / Table of Contents: Zusammenfassung Es wurden 41 Patienten mit multipler Sklerose im akuten Schub mit drei bis vier intrathekalen Dosen von 40 mg Triamcinolone Retard behandelt. Liquorproben wurden bei der ersten und letzten Lumbalpunktion entnommen und auf IgG und Albumine untersucht. Bei 85% der Fälle fand sich eine Reduktion des IgG-Gehaltes in der letzten Liquorprobe, verglichen mit den Anfangswerten. In ähnlicher Weise ergab sich auch eine Verminderung des IgG/Albumin-Verhältnisses in den letzten Liquorproben in 78% der Fälle. Beide Ergebnisse sind statistisch signifikant.
    Notes: Summary Forty-one patients with multiple sclerosis (MS), in the acute exacerbation phase of the disease, were treated with three or four intrathecal injections of triamcinolone retard, 40 mg. Cerebrospinal fluid (CSF) specimens were collected at the first and at the last lumbar puncture, and analyzed for IgG and albumin. There was a decrease of CSF IgG concentration in the specimens of 85% of the cases which were collected at the last lumbar puncture, compared to the initial concentration. Similarly, the CSF IgG/albumin ratio in the last specimens collected were reduced in 78% of the cases. Both these results are statistically significant.

    Description / Table of Contents: Sommario È stato precedentemente dimostrato che sia la proteina basica della mielina (PBM) che la S-100 vengono liberate nel liquido cefalo-rachidiano (LCR) durante in periodi di esacerbazione della sclerosi multipla (SM). Al fine di approfondire ulteriormente il significato patobiologico della liberazione di queste due proteine nel LCR abbiamo eseguito uno studio quantitativo di PBM e S-100 in dieci malati di SM durante un periodo di 5 settimane successive ad una ricaduta. La PBM è risultata dosabile durante le prime tre settimane, mentre la S-100 è risultata essere presente nel LCR durante l'intero periodo di osservazione, almeno in alcuni dei pazienti. La PBM ha raggiunto i suoi maggiroi livelli durante le prime due settimane. La S-100, invece, durante la terza settimana, dopo di che vi è stata una netta riduzione dei suoi livelli liquorali. Questa differenza nei tempi di presenza di PBM ed S-100 nel LCR è probabilmente dovuta alla differente origine biological delle due proteine. La PBM, infatti, è marcatrice di lesione della guaina mielinica, la S-100 invece, con più probabilità, di attività dellule astrocitarie.
    Notes: Abstract It has previously been demonstrated that both Myelin Basic Protein (MBP) and S-100 are released in the cerebrospinal fluid (CSF) of multiple sclerosis (MS) patients during acute phases of exacebation of the disease. In order to investigate the pathobiological significance of the release of these two proteins into the CSF, MBP and S-100 were assayed in 10 MS patients during the five weeks following onset of an acute exacerbation. MBP was detectable in CSF during the first three weeks after exacrebation, while S-100 was detectable during the entire period of observation, at least in some of the patients. MBP reached its highest CSF concentrations during the first two weeks while S-100 did so in the third week, decreasing thereafter. This difference in time of presence of MBP and S-100 in the CSF is probably due to the different biological origin, MBP being a marker of myelin sheath injury, and S-100, more probably, of astrocytic activity.

    Description / Table of Contents: Sommario Quarantuno pazienti con sclerosi multipla (SM) certa sono stati introdotti in una sperimentazione in doppio cieco levamisolo/placebo mentre erano nella fase stazionaria della malattia. Ventidue di essi hanno ricevuto levamisolo, 150 o 200 mg una volta a settimana per quattro anni, ed altri 19 hanno ricevuto placebo con lo stesso schema posologico. L’assegnazione ad uno dei due gruppi è stata effettuata a caso. I pazienti che hanno presentato una chiara esacerbazione prima dello scadere dei quattro anni non hanno continuato l’assunzione e sono stati considerati come risultati negativi. Nel gruppo trattato con levamisolo 8 pazienti hanno presentato una esacerbazione e 14 no. Nel gruppo che ha ricevuto placebo 14 hanno presentato una riaccensione e 5 no. Questa differenza è risultata essere statisticamente significativa. In questo studio si dimostra che il levamisolo riduce significativamente il numero dei pazienti che presentano una esacerbazione in un periodo di 4 anni. Tuttavia il fatto che non tutti i pazienti hanno ricevuto un tale beneficio potrebbe suggerire che differenti quadri immunopatologici possono essere alla base di ciò che noi usualmente chiamiamo SM.
    Notes: Abstract 41 patients with definite multiple sclerosis (MS) in the stationary phase entered this four year double-blind levamisole-placebo controlled study. 22 patients were treated with levamisole, 150 or 200 mg once a week for a 4 year period, and other 19 with placebo with the same schedule. Patients were put in one of the two groups at random. The treatment was then stopped for those patients who presented a clear exacerbation before the end of the 4 year trial period, and these cases have been considered as negative. Of the group treated with levamisole 8 patients presented an exacerbation during the observation period, and 14 did not. The group treated with placebo presented 14 subjects who had exacerbations and 5 patients who did not. The difference between the two groups was statistically significant. This study demonstrates that levamisole significantly reduced the number of MS patients with acute relapse during the 4 year period of treatment. Nevertheless, not all patients were free from relapse: that could probably suggest that different immunopathological backgrounds may underlie what we usually call MS.

    Description / Table of Contents: Sommario I marcatori liquorali sono un utile strumento per determinare la progressione della malattia ele fasi di attività in alcuni disordini neurologici che necessitano di parametri utili a valutare l’efficacia di un trattamento, o a studiare l’evoluzione patobiologica in follow-up finalizzati alla ricerca. Gli autori passano in rassegna un certo numero di proteine liquorali soffermandosi sulle loro proprietà biologiche, sui metodi analitici, sull’utilizzo a scopi clinici. Vengono prese in considerazione: la proteina basica della mielina, la proteina S-100, la proteina acida gliale fibrillare, la proteina di adesione neuronale N-CAM, la enolasi neurono-specifica e alcune altre.
    Notes: Abstract Cerebrospinal fluid (CSF) markers are a useful tool for determining disease progression or activity in some neurological disorders which need parameters both for evaluating treatments and investigating pathobiological evolution in researchoriented follow-up. A number of CSF proteins are reviewed with data on biological properties, analytical methods, clinical usefulness of: myelin basic protein, S-100 protein, glial fibrillary acidic protein, neural-cell adhesion molecule, neuron-specific enolase and others.
