    Description / Table of Contents: Zusammenfassung In 160 Versuchen am Kaninchen wurde die Wirkung von Chlorpromazin, das besonders in den für die Wärmeregulation wichtigen zentralen Gebieten des Hypothalamus und der Formatio reticularis angereichert wird, auf die normale Körpertemperatur und die Fieberreaktion nach Gabe von Lipopolysacchariden gramnegativer Bakterien untersucht. Gemessen wurden die Rectal- und Ohrtemperatur, die Atem- und Herzfrequenz. Es ergab sich: 1. die Rectaltemperatur des unbeeinflußten Kaninchens wird bei einer Umgebungstemperatur von 22° C in Abhängigkeit von der Dosis gesenkt, 2. das Lipopolysaccharid-Fieber läßt sich durch Vorgabe von mehr als 1 mg/kg Chlorpromazin abschwächen oder unterdrücken, 3. die Reaktion in Empfängertieren durch Plasmaübertragung von fiebernden Spendertieren kann drei verschiedene Verlaufsformen ergeben: eingipflige, zweigipflige und afebrile. Eine Beziehung zur Größe des Spendertierfiebers bestand dabei nicht. Die Ergebnisse werden hauptsächlich durch die zentralen Angriffspunkte des Chlorpromazins erklärt.
    Notes: Summary Chlorpromazine concentrates particularly in that central regions of the CNS important for the thermoregulation, in the hypothalamus and the formatio reticularis. Therefore in 160 experiments on rabbits the effect of chlorpromazine was tested at the normal body temperature and the fever reaction after medication of lipopolysaccharides (LPS) from gramnegative bacteria. Measured were the rectal- and ear-temperature, the heart- and respiration-frequency. It resulted that: 1. the rectal temperature of untreated rabbits at environmental temperature of 22°C ± 2°C is lowered, dependant on the dose, 2. the LPS-fever is diminished or suppressed after premedication of 〉 1 mg/kg chlorpromazine, 3. the reaction in the recipient animal may proceed in three different types of fever: mono- and biphasic curves and an afebrile one. A relation to the height of fever of the donor animal was not existant. Analogue to other experiments with central acting pharmaca and local cerebral temperature-stimulations in the area of the anterior hypothalamus as well as considering the distribution of chlorpromazine in the CNS these results are explained by specific effects of chlorpromazine in the hypothalamus and the formatio reticularis.

    Notes: Phase microscopic investigations of Kolmer-fixed, depigmented sections of the adult chicken retina have provided photomicrographic evidence of the existence of three different photoreceptors: single rods, single cones, and double cones. The rod extends the entire thickness of the visual cell layer and is characterized by a uniformly thick outer segment and a hyperboloid-containing inner segment which is devoid of an oil droplet. The single cone is the shortest element; it contains a red oil droplet. The double cone consists of two unequal members, a tall, slender chief cone and a broad accessory cone. The chief component contains a large yellow oil droplet, whereas the accessory cone houses a small, oval, yellowish-green droplet and a characteristically large, oval paraboloid. The rod hyperboloid and the accessory cone paraboloid contain glycogen. No colorless droplets have been observed. Owing to the close association between oil droplet color and cone type, three colored layers of oil droplets are formed within the thickness of the retina: a proximal row of red droplets (the short, single cones), an intermediate layer of yellowish-green droplets (the accessory cones), and a distal row of yellow droplets (the tall chief cones).
