Crone, C., Johnsen, L. L., Biering-Sørensen, F., Nielsen, J. B.
The purpose of the present study was to investigate the pathophysiological role of reciprocal facilitation between antagonistic motoneuron pools in spasticity. The soleus H‐reflex was...
Investigation of Planktonic Foraminifera with TOF-SIMS (2002)
Crone, C., Vering, G., Hönisch, B., Bijma, J., Arlinghaus, H. F.
Morita, H., Crone, C., Christenhuis, D., Petersen, N. T., Nielsen, J. B.
The aim of the study was to investigate whether impaired control of transmission in spinal inhibitory pathways contributes to the functional disability of patients with spasticity. To this end,...
Changes in transmission across synapses of Ia afferents in spastic patients (1995)
Nielsen, J., Petersen, N., Crone, C.
The transmission across synapses of la afferents on spinal motor neurons was investigated in 30 healthy subjects and 25 spastic multiple sclerosis patients. Slow passive stretch (17°/s) of the...
Disynaptic reciprocal inhibition of ankle extensors in spastic patients (1994)
Crone, C., Nielsen, J., Petersen, N., Ballegaard, M., Hultborn, H.
The soleus Hoffmann-reflex (H-reflex) was conditioned by a preceding stimulation of the common peroneal nerve in 74 healthy control subjects and 39 patinets with spasticily in the lower extremities...
Bundgaard, M, Frøkjaer-Jensen, J, Crone, C
In electron microscopy studies of the endothelial vesicles in frog mesenteric capillaries, an accidental observation was made concerning vesicular organization. When tannic acid was added to already...
Electrical resistance of muscle capillary endothelium.
A recently developed technique for in vivo determination of the electrical resistance of vascular endothelium in microvessels was applied to the vessels in a thin frog muscle, m. cutaneus pectoris....
1. The inhibition of the soleus Hoffmann reflex (H reflex) during voluntary dorsiflexion of the foot--henceforth referred to as 'natural' reciprocal inhibition--was found to be initiated 50 ms before...
Crone, C, Hultborn, H, Kiehn, O, Mazieres, L, Wigström, H
1. During investigation of the tonic stretch reflex in the unanaesthetized decerebrate cat we observed that a short train of impulses in Ia afferents from the soleus muscle (or its synergists) may...
Potassium transport across rat alveolar epithelium: evidence for an apical Na+-K+ pump.
Basset, G, Bouchonnet, F, Crone, C, Saumon, G
1. Experiments were performed on rat lungs into which various solutions were instilled whilst the lungs were perfused with either whole blood or Ringer solution. Instillation of ion-free glucose...
Reciprocal Ia inhibition between ankle flexors and extensors in man.
Crone, C, Hultborn, H, Jespersen, B, Nielsen, J
1. Reciprocal inhibition between antagonist muscle groups at the ankle has been investigated in sixty healthy subjects. Hoffmann reflexes (H reflexes) in the soleus and tibialis anterior muscles were...
Basset, G, Crone, C, Saumon, G
1. Experiments were performed on isolated rat lungs perfused with Ringer solutions containing red cells. The goal was to clarify the role of active transport of Na+ for the absorption of fluid across...
Basset, G, Crone, C, Saumon, G
1. The purpose of the investigation was to characterize the luminal membrane and the paracellular pathway of rat lung alveolar epithelium. Experiments were performed on lungs in situ instilled with...
Selectivity to passive permeation of small ions through capillary walls was studied by measurements of diffusion potentials in response to ionic gradients established across capillary walls in frog...
