Artificial stripping of large mouth buffalo (.I.Istiobus cyprinellus./I.) using carp pituitary, GnRH analog and dopaminergic inhibitor Isofloxythepin
Kouřil, J. ; Hamáčková, J. ; Barth, Tomislav ; Hulová, Irena ; Barthová, J.
The ovulation and artificial stripping of large mouth buffalo was achieved by the administration of homogenate or water extract of carp hypophysis or by GnRH analogue and á-dopaminergic inhibitor Isofloxythepin. The dosing of GnRH aanalogue for coplete ovulation is to be defined.
The Effect of pyroglutamic fragments of vasopressin and oxytocin on the retention of memory after intoxication by neurotoxins QB and DSP-4 in rats
Koupilová, M. ; Patočka, J. ; Barth, Tomislav
Effects of six analogs of AVP fragment 4-9 on cognitive impairment induced by cholinotoxin 3-quinuclidine benzilate (QB) or by noradrenotoxin (DSP-4) were investigated by means of Y-maze with aversive stimulation and T-maze with appetitive stimulation in Wistar rats. QB and DSP-4 induced a severe learning deficit in pretrained animals. Single preventive administration of the peptides reversed the QB and DSP-4 induced impairment of the retention of memory.
Receptor-selective enkephalin analogs
Pencheva, N. ; Barth, Tomislav
We investigated the opioid profiles of [Cys2]-enkephalin (enk) analogs and [D-Ala2,Leu5]-enkephalyl-Arg (dalargin) in in vitro bioassay system. The results showed that incorporation of hydrophilic Cys(O2NH2)2 into the enk molecule greatly increases the potency and selectivity of the analogs to ë-opioid receptors, while substitution of D-Ala2 and Arg6 into the molecule of [Leu5]-enk, to ć-opioid receptors.
