    Notes: Progress in propagation of milkfish has been impeded by the shortage of mature broodstock. This study was a first step toward revealing the environmental cues for the maturation of milkfish. Experiments were carried out during 1978-1985 in an indoor tank (5.2 × 4.8 × 13 m) under photoperiod control and in an outdoor tank (63 × 5.4 × 13 m). In two controlled, long-photoperiod regime experiments, 86 and 83% of the fish matured, the highest percentages yet reported. In these experiments, milkfish matured one month earlier than the normal spawning season, two months after the fish were exposed to the long daylight regime. Only 21% of the fish under a natural photoperiod regime in the outdoor tank matured. Results of the current study suggest that a change and increase in photoperiod are necessary for the onset of maturation.

    Effect of orally-administered 17α-methyltestosterone on spermatogenesis in immature milkfish, Chanos chanos Forsskal (1986)

    Notes: Diets containing 17α-methyltestosterone (17α-MT) were fed to milkfish, Chanos chanos, both during the spawning season (experiment 1) and after (experiment 2). The daily dosage of 17α-MT per kg of body weight was either 25 mg or 12.5 mg in experiment 1, and either 12.5 mg or 6.25 mg in experiment 2. The fish in both experiments were smaller than the minimum mature size previously reported. After 12 weeks of treatment, the treated fish had GSIs that were four times higher than the control fish in both experiments. Histologically, the testes of the control fish had only spermatogonia, in contrast to spermatozoa in the treated fish. However, no male possessed running milt. So 17α-MT induced spermatogenesis but not spermiation in the immature-sized milkfish.

    Effects of 17α-methyl-testosterone on spermatogenesis and spermiation in the grey mullet, Mugil cephalus L. (1985)

    Notes: Diets containing 17α-Methyl-testosterone were given to grey mullet, Mugil cephalus, during the refractory period in its reproductive cycle at the dosage of 25 mg or 12.5mgkg−1 fish. Fish in experiment I were fed the diet containing methyl-testosterone every day for 55 weeks, and fish in Experiment II were fed the same diet daily for the first 10 weeks, and three times per week for the next 42 weeks. Fish were checked for the presence of sperm weekly or bi-weekly and tested for fertility during the spawning season. Terminal gonad weights and histology were compared with control groups. This study demonstrated that male mullet will mature 3 weeks or less by oral administration of 12.5 mg methyl-testosterone kg−1 fish daily. Fish can then be maintained in mature condition by feeding them methyl-testosterone at 12.5 mg kg−1 three times per week.

    Synchronization of protoplasts from Glycine max (L.) Merr. and Brassica napus (L.) (1986)

    Notes: Abstract Cells of Glycine max originating in a suspension culture and cells of Brassica napus prepared from hypocotyls were synchronized. Synchronization was achieved by preparing protoplasts in the usual way and subsequently letting the protoplasts regenerate into cells by removing the cell-wall-digesting enzymes. More than 70% of the cells had divided synchronously at the end of the first cycle as determined by the mitotic index. The high frequency of mitosis critically depended on the osmolality of the medium. The duration of the S-phase was estimated by measuring the activity of thymidylate kinase as well as incorporation of [3H]deoxythymidine into acid-insoluble material. The data indicate that synchronization is induced by resetting the cell cycle.

    Calcinose und Spaltensystem der inneren elastischen Membran der geschlängelten Milzarterien (1968)

    Description / Table of Contents: Zusammenfassung Bei der makroskopischen Darstellung von Kalkablagerungen treten die calcifizierten Anteile der inneren elastischen Membran auch an den Milzarterien in Form von gepaarten schwarzen Kalkbändern oder ihren Fragmenten zutage. Diese stellen mineralisierte Ränder von Membranspalten dar und lassen daher die Form und Ausdehnung der Membranlücken an der Innenwand der Arterie makroskopisch erkennen. Die äußeren, sich ausbuchtenden Bögen der geschlängelten Milzarterien zeigen an ihrer inneren elastischen Membran ein stark ausgebildetes Spaltensystem und erweisen sich zugleich als ein bevorzugter Sitz der Membrancalcinose. Die stärkere Entwicklung des Spaltensystems der primären inneren elastischen Membran an den äußeren Bögen der Krümmer stellt offenbar die Folge einer hier stattfindenden Wanddehnung dar, die auch an der Verdünnung der Wand und an dem Auseinanderweichen der adventitiellen elastischen Geflechte erkennbar wird.
    Notes: Summary Calcific deposits have been demonstrated grossly in the internal elastic membrane of splenic arteries. They are seen on the margins of membrane gaps as pairs of continuous or interrupted black bands (“calcific bands”). When the calcification is pronounced, nearly the whole system of ramifying and communicating membrane gaps is discerned grossly on the inner surface of the arteries. On the inside of the convex segments of the tortuous splenic arteries the membrane gaps are more numerous and wider then on the inside of the concave segments. Consequently, the calcific deposits are commoner on the convex segments. The development of gaps in the internal elastic membrane on the convex segments is probably the result of distension by the greater hydraulic pressure on these parts of the tortuous artery. This also leads to thinning of the media and interruption of the elastic networks in the adventitia in these parts of the artery.

    Reduced biological half-life of plasma prostacyclin in pre-eclampsia (1988)

    Notes: Summary The biological half-life of prostacyclin was short (5.02±2.10 min) in 5 out of 7 patients with pre-eclampsia; in the remaining two patients the half-life was normal at 9.78 and 10.27 min, respectively. Four weeks after delivery, the half-life was 5.83 min in one patient but had returned to normal 10.16±1.77 min) in the other four. In normal pregnancy and healthy nonpregnant females the values were within the normal range. The shortened half-life PGI2 may account for a decreased local availability of biologically active PGI2 with the consequent decrease in placental perfusion, growth retardation and thrombosis which are often seen in pre-eclampsia.

Bei einer 34 jährigen Patientin kam es im Bereich der Wange zur typischen Noma, die unter Penicillin-Infusionen abheilte, jedoch als Spätkomplikation die oft beschriebene Lungen- und Pleurabeteiligung aufwies. Die Behandlungsmaßnahmen werden ausführlich erörtert.
    Notes: Summary After a thorough presentation of the available literature concerning Noma, a case history of a 34 year old woman who had a typical Noma in the cheek is reported. This was successfully treated with penicillin infusion but it presented the usual late complications of the lungs. The methods of treatment has been extensively discussed.
