    Notes: Sectioned and formed roast beef, vacuum mixed and heat processed in either retortable pouches or cans, had a lower cook yield than its nonvacuum mixed counterpart. Vacuum mixing had no significant influence on increasing particle-to-particle cohesion (binding strength). Sectioned and formed roast beef cooked in retortable pouches at 121°C (Fo= 6.0) had a higher cook yield and binding strength than product processed at 110°C (Fo= 6.0). Processing the canned product at 121°C (Fo= 6.0) as opposed to 110°C (Fo= 6.0) resulted in no improvement of cook yield or binding strength. Overall, product processed in retortable pouches had a higher binding strength, but a lower cook yield than product processed in cans.

    Notes: The effects of vacuum mixing and precooking on the binding strength and cook yield of restructured steaks were evaluated. Vacuum mixing was responsible for an increased binding strength of the restructured steak, but had no effect on the cook yield. Precooked, reheated steaks had a significantly higher binding strength, but a lower cook yield than steaks cooked from the frozen, raw state.

    Description / Table of Contents: Zusammenfassung Kurz nach der Einführung des Wirkstoffes (1945) konnten Vergiftungen mit Diphenhydramin beobachtet werden. Seit Diphenhydramin, zusammen mit 8-Chlortheophyllin als Dimenhydrinat im Handel, anstelle des gefährlicheren Diethylpentenamid als rezeptfreies Schlafmittel angeboten wird, stiegen auch die Zahlen von Vergiftungen und Verkehrsunfällen unter Diphenhydramin-Einfluß. Der Vergleich von vier klinisch behandelten und überlebenden Patienten mit sieben unter Diphenhydramin-Einfluß verunfallten Verkehrsteilnehmern zeigt, daß hier massive Intoxikationen bei erheblichem Tablettenmißbrauch vorgelegen haben. Aus den Verhältnissen der Diphenhydramin-Konzentration in Blut und Urin sowie den Konzentrationen der als Hauptstoffwechselprodukt entstehenden Diphenmethoxyessigsäure lassen sich wertvolle Hinweise auf chronischen Mißbrauch bzw. den Aufnahmezeitpunkt der Tabletten gewinnen. Bei verschiedenen tödlichen Vergiftungen wurde unter anderem eine massive Vergiftung vorgefunden, die zu bisher noch nicht beschriebenen hohen Konzentrationen von Diphenhydramin in Körperflüssigkeiten und Geweben geführt hat.
    Notes: Summary Several poisonings by diphenhydramine were reported shortly after it had been introduced as an antihistamine in 1945. In the Federal Republic of Germany its combination with 8-chlorotheophylline (dimenhydrinate) is available as a hypnotic without prescription. Replacing the dangerous diethylpentenamide diphenhydramine is a drug which is also often abused. Fatal poisonings, suicide attempts, and traffic accidents were increasingly observed. In seven cases drug-influenced road users caused traffic accidents. We observed blood concentrations of diphenhydramine as high as in four cases of clinically treated patients after ingestion of large doses. This indicates a serious drug abuse. The measurement of the concentration of diphenhydramine and its major metabolite (diphenmethoxy acetic acid) in blood and urine is a means of recognizing chronic use and misuse of diphenhydramine. As the metabolite accumulates in blood one may find an elevated level after multiple dosing. Shortly after taking a single dose no or only low metabolite concentration is found. The concentration of diphenhydramine and its metabolite was measured in several fatal cases. In one of these cases the concentration in body fluids and tissues was in a range not observed until now.

    Description / Table of Contents: Summary The effects of l-n-cocaine and d-ψ-cocaine on guinea-pigs and isolated organs have been studied. 1. Reflexes of posture and adjustment as specified by Magnus, were paralysed similarily by l-n-cocaine d-ψ-cocaine. 2. Unlike l-n-cocaine, however, d-ψ-cocaine failed to render isolated organs (blood-vessel-preparation, atrium, and gut) more sensitive to adrenaline. 3. While l-n-cocaine produced symptoms of central sympathetic stimulation, as hyperthermia and hyperglycemia, no such effects were obtained by d-ψ-cocaine. The hyperthermic and hyperglycemic response to l-n-cocaine was inhibited by chlorpromazine (2.0 mg/kg s.c.). 4. Unlike l-n-cocaine, d-ψ-cocaine failed to antagonize barbiturate anesthesia. 5. In chronic experiments d-ψ-cocaine and l-n-cocaine produced similar toxic symptoms, as reduction in body weight and fat deposition in the central areas of the liver lobules. While l-n-cocaine and d-ψ-cocaine had similar toxic effects on the CNS (convulsions, paralysis), d-ψ-cocaine failed to induce symptoms of sympathetic stimulation. These findings suggest, that the euphoristic effect of l-n-cocaine which is entirely missing in d-ψ-cocaine as well, might be based on the stimulating action on sympathetic nervous centres.
    Notes: Zusammenfassung An Meerschweinchen und isolierten Organen wurden Wirkungen von l-n-Cocain und d-ω-Cocain vergleichend untersucht. Es ergab sich 1. l-n-Cocain und d-ω-Cocain lähmen gleichartig die Stell- und Haltereflexe nach Magnus. 2. d-ω-Cocain zeigte an isolierten Organen (Gefäßpräparat, Vorhof, Darm) keine Sensibilisierung für Adrenalin wie l-n-Cocain. 3. Zentrale sympathische Erregungserscheinungen (Fieber, Hyperglykämie) werden nur von l-n-Cocain, nicht von d-ω-Cocain gegeben. Chlorpromazin (2,0 mg/kg s.c.) wirkte antagonistisch bei der Cocainhyperthermie und Hyperglykämie. 4. d-ω-Cocain vermochte im Gegensatz zu l-n-Cocain nicht, eine Barbiturnarkose zu unterbrechen. 5. Bei chronischen Versuchen ergaben d-ω-Cocain und l-n-Cocain gleiche Vergiftungssymptome (Gewichtsabnahme, zentrale Leberverfettung). Das Fehlen sympathischer Erregungserscheinungen nach d-ω-Cocain bei sonst gleichartigen Wirkungen am ZNS (Krämpfe, Lähmungen) lassen vermuten, daß die euphorisierende Wirkung von l-n-Cocain, die bei d-ω-Cocain völlig vermißt wird, ebenso auf der stimulierenden Wirkung sympathischer Zentren im ZNS beruht.

    Notes: Summary Voltage jump-current relaxation experiments have been performed with valinomycin-doped membranes of mixtures of 1,2-dipentadecylmethylidene-glycero-3-phosphorylcholine (PC) and charged-phosphatidic acid (PA). Both relaxation processes predicted by a simple carrier model could be resolved which allowed the calculation of the rate constants of the Rb+ transport. The dependence of the rate constants on the membrane composition indicates that (i) the lipids in the mixed membranes are homogeneously distributed and that (ii) no major difference exists between the composition of the membrane and that of the torus. The analysis of the stationary conductance data, however, shows that the valinomycin content of the mixed membranes depends strongly on their lipid composition. Addition of Ca++ ions to a 1∶1 mixture induces a phase separation into PA domains of very low conductivity and PC-enriched regions of high conductivity. Half saturation is reached atc ca=5×10−4 m. At 10−2 m Ca++ in the aqueous phase, the rate constants clearly indicate that all PA molecules are electrically “passivated” and only pure PC domains contribute to the membrane current. A detailed picture is thus derived of the coupling of a model transport system to the externally triggered membrane reorganization.

    Description / Table of Contents: Summary The effect of analeptic and narcotic drugs on vagal respiratory reflexes has been investigated in 38 rats after bilateral vagotomy. Peripheral effects on the reflex arch (tension-receptors, neuromuscular synapsis) were eliminated by the experimental procedure (stimulation of the cervical N. vagus, registration from the N. phrenicus). Chemical respiratory stimulants were kept constant by artificial respiration. A stimulation of less than 20 imp./sec produced in decerebrated animals and in urethane-anaesthesia inspiratory effects. An exspiratory standstill of respiration was observed, when higher frequencies were applied. This apnoe was, however, interrupted later on by an inspiratory action from the phrenic nerve although stimulation and artificial respiration continued (escape-phenomenon). If the depth of anaesthesia was increased by using doses of urethane or barbiturates (barbital sodium, aprobarbital) which are known to depress spontaneous respiration, inspiratory and exspiratory reflexes decreased or were extinguished. Analeptic drugs (pentylenetetrazol, bemegride) acted as antagonists. Prethcamide failed to show effects on respiratory vagal reflexes in spite of its powerful excitatory effect on respiration. It is assumed that high doses of anaesthetics act more pronounced on the afferent system than on the spontaneous rhythm of respiration.
    Notes: Zusammenfassung An 38 bivagotomierten Ratten wurde die Wirkung von narkotischen und analeptischen Substanzen auf die vagalen Atmungsreflexe untersucht. Periphere Wirkungen am Reflexbogen (Dehnungsreceptoren, neuromuskuläre Synapse) waren bei der Versuchsanordnung (Reizung des Halsvagus, Ableitung des N. Phrenicus) ausgeschaltet. Die chemischen Atmungsantriebe wurden durch künstliche Beatmung möglichst konstant gehalten. Bei Tieren in Urethannarkose und nach Decerebrierung ergaben Reizungen mit Impulsfrequenzen unter 20 Imp./sec inspiratorische Effekte, während höherfrequente Reizungen zu exspiratorischen Stillständen führten. Diese Apnoe wird aber trotz fortgesetzter Reizung und künstlicher Atmung nach einiger Zeit von inspiratorischen Phrenicusaktionen durchbrochen („escape“-Phänomen). Vertiefungen der Narkose mit Dosen, die die Spontanatmung deutlich deprimieren, führten sowohl mit Urethan als auch mit Barbituraten (Barbital-Na, Aprobarbital) zur Abschwächung bis zum Erlöschen sowohl der inspiratorischen als auch der exspiratorischen Reflexe. Analeptica (Metrazol, Bemegrid) wirkten antagonistisch. Prethcamid zeigte trotz starker atemanaleptischer Wirkung keine Effekte auf den vagalen Atmungsreflex. Es wird vermutet, daß hohe Dosen von Narkotica das afferente System stärker beeinflussen als die spontane Atemrhythmik.
