Simultane Messungen der lokalen Myokarddurchblutung mit Wärmeleitmessern und 85Krypton-Clearance
In dogs the regional blood flow of the myocardium of the left ventricle was measured simultaneously on the same site by two methods. One was the continuous recording of heat clearance from a heated junction of...

A major histocompatibility complex in the toadxenopus laevis (Daudin)
The genetic relationship between mixed leukocyte reaction (MLR), skin graft rejection, and some red blood cell antigens has been studied in a sibship of the toadXenopus laevis. MLR ty** was achieved using blood...

Determination of glomerular intracapillary and transcapillary pressure gradients from sieving data II. A physiological study in the normal dog
The two theoretical models proposed previously to calculate the intracapillary and transcapillary glomerular pressure gradients from the sieving of macromolecules such as PVP have been used to analyse in 22 no...

Genetic aspects of the tolerance to allografts induced at metamorphosis in the toadXenopus laevis
Genetic aspects of tolerance to allografts induced at metamorphosis in the toadXenopus laevis were studied in one sibship expressing four different major histocompatibility complex (MHC) haplotypes. Tolerance by ...

The effect of thymectomy on the mixed leukocyte reaction and phytohemagglutinin responsiveness in the clawed toadXenopus laevis
In the clawed toadXenopus laevis, thymectomy at 7 days of age abrogates the phytohemagglutinin response of leukocytes and the mixed leukocyte reaction.

The antibody response during amphibian ontogeny
The maturation of the anti DNP-response in adult and larval amphibians has been compared in two species of anurans,Rana catesbeiana andXenopus laevis. IgM responses were very similar in larvae and adults of both ...

The genetic control of histocompatibility reactions in natural and laboratory-made polyploid individuals of the clawed toadXenopus
Family studies inXenopus laevis (2n=36 chromosomes) demonstrate the expression of a single major histocompatibility complex in this species. Mixed leukocyte studies in two families ofXenopus vestitus (2n=72 chrom...

Adenylate cyclase and phosphodiesterase from brain tissue: Different stabilities during incubation of cerebral cortical slices
Adenylate cyclase and phosphodiesterase were prepared from brain slices from guinea-pig. The specific acitivity of adenylate cyclase declined rapidly with increasing incubation time of tissue slices, while pho...
