[Winuron - alternative single-dose therapy of gonorrhea]. / Winuron - Alternative Einmaltherapie der Gonorrhoe.

152 ambulatory patients suffering from gonorrhoea were treated with Winuron in an open clinical trial. A single oral dose of rosoxacin 300 mg proved to be sufficient to cure 97.4% of the patients. Follow-up examination revealed only 4 cases of Neisseria gonorrhoea left. Already 3 days after therapy, the clinical symptoms had subsided in 84.1% of the patients. The substance was well-tolerated. Side effects were observed in 14.5% of the cases, being mild and transitory, though. Good and antibacterial efficacy of rosoxacin in vitro as well as the high healing quotient in combination with the shortest possible duration of therapy make Winuron a valuable alternative to penicillin.

[Temperature dependence of courtship in male guppies, Poecilia reticulata Peters (Pisces, Cyprinidae)]. / Zur Temperaturabhängigkeit der Balz männlicher Guppys, Poecilia reticulata Peters (Pisces, Cyprinidae).

In poikilothermal animals, modes of behaviour as well as other physiological functions are dependent on the environmental temperature. Individual adaptation can decrease or cancel out this dependency. In experiments involving abrupt and slow temperature changes, we were able to prove temperature compensations and stress effects in the courting behaviour of the male Poecilia reticulata.
