JOURNAL FREE ACCESSIn der vorliegenden Arbeit wurde bei 134 Körperhälften der Katze eine genaue Untersuchung in bezug auf die Zahl der Wurzeln, die Kombinationen derselben und die Art und Weise der Geflechtbildung dargestellt und vor allem folgendes ermittelt:
1) Als Wurzeln des Plexus brachialis kommen bei der Katze C5-Th2vor, und zwar sind C6-Th1 die konstanten Wurzeln. C5 tritt nach mir 11.96% auf, The 49.25%.
2) Als konkrete Kombinationen dieser Wurzeln werden 4 Gruppen beobachtet, d. h. die Kombination 1) C5-Thl (8.21%),2) C5-Th2 (3.73%),3) C6-Thl (42.54%) und 4 )C6-Th2 (45.5 2%).
3) Bezügl ich der A rt und Weise der Geflechtbildung wurden hier im Ganzen 16 Formen unterscheiden. Darunter stellen die Form 6-4 den normalen Typus (67.16% ), die ubrigen Formen (32.84%) hingegen Variationen dar. Den Befund von mir habe ich schon der Übersichtlichkeit halber in der Tabelle 6 zusammengestellt.
4) Der Plexus brachialis neigt bei der Katze mehr oder weniger weiter kaudal zu liegen als beim Menschen.View full abstractDownload PDF (4862K) -

JOURNAL FREE ACCESSIn der vorliegenden Arbeit wurde die Ursprungsweise der kurzen Äste des Plexus brachialis bei 30 Körperhälften von der Katze näher untersucht und vor allem folg endes ermittelt:
1) In der Regel besteht der N. supraclavicularis nur aus C6 allein (80.00%).
2) Der N. suprascapularis bildet sich gewOhnlich durch die Vereinigung des C6 und C7 (90.00%).
3) Bei der Katz finden sich 2-5, meistens (73.33%) aber 3 Nn. subscapulares und beim Vorliegen von 3 Nerven ist am häufigsten der 1. von C6 und C7 zusammengesetzt, der 2. nur von C7 allein, der 3. von C6 und C7.
4) GewOhnlich (80.00%) sind bei der Katze 2 Nn. thoracici ventraIes (N. pectoralis lateralis et medialis) vorhanden. Der N. pectoralis lateralis stammt meis tens nur aus C7 (63.33%). Der N. pectoralis medialis bildet sich am Oftesten durch C8 u nd Th1 (+Th2) (66.67%).
5) Meistens ist der N. thoracodorsalis von C7 und C8 zusammengesetzt (89.69%).
6) Der N. thoracicus longus kommt gewöhnlich nur aus C7 allein (83.33%).View full abstractDownload PDF (1427K) -

JOURNAL FREE ACCESSThe relationship between renal function and ADH was investigated in 78 patients with renal diseases. Results obtained were as follows:
1) The defect of concentration power in nephropathy is not due to the lowering of secretion of blood plasma ADH but to the lowering of sensitivity of the renal tubule and the collecting tube for ADH, diuresis by osmotic pressure, and increas e of blood flow in medullary segment.
2) In edema of acute nephritis and of nephrotic syndrome, ADH does not have any important significance.
3) Plasma ADH is inversely correlated with Ccr.
4) The exogenous pitressin reaction is proportional to TcH2O
5) If TcH2O is obtained by mannitol instillation, it is possible to know the reaction for exogenous pit ressin from Y=-0.69 X-0.05.
6) The effective time for exogenous pitressin is proportional to TcH2OView full abstractDownload PDF (2740K) -

JOURNAL FREE ACCESS1. When the vas deferens isolated from male guinea-pig was set on a Magnus'apparatus in an isotonic sucrose medium saturated with pure oxygen at 30 to 31 °C, the addition of potassium chloride at small amount as 5.6 mM could induce the contraction in the preparation. As the medium contained only 0.07% sodium bicarbonate f and 0.1% glucose, it was clear that the potassium ions played a leading role in the contraction process of the smooth muscle.
2. When calcium or sodium chlo ride was added in place of the potassium chloride, each of them could scarcely induce the contraction at each any concentration, and, moreover, when the calcium chloride at the concenntrations more than 1.7 mM or the sodium chloride at the concentrations more than 10.1 mM was pre-added to the sucrose medium, the potassium iuduced contraction could be scarcely seen.
3. From the dose-response curve of the preparation to the added po tassium chloride doses and the influence of the pre-added calcium chloride at 0.55 mM on it, the potassium action may be competetively antagonized by the calcium ions on the probable receptor for potassium in the tissue.
4. The similar action to tha t of the potassium chloride was seen when rubidium chloride at 1.5mM or cesium chloride at 3.0mM was added in place of the potassium chloride. Their actions at these amounts were, however, scarcely influenced by the pre-added calcium chloride.
5. The potassium induced contraction was seen even when the preparation had been kept in the isotonic sucrose medium whose pH was adjusted by tris-HCI buffer in place of by the sodium bicarbonate.
6. From these results, it was assumed that the potassium ions may be the essential ions in the initiation of the contraction process in the smooth muscle but that calcium ions or sodium ions may inhibit the initiation of this contraction process.View full abstractDownload PDF (4169K) -

JOURNAL FREE ACCESSWith the use of MEDIAC a study was made of the effects of average evoked potential due to afferent stimulation of the sciatic nerve upon the wearing of the contact lens. The results obtained were as follows:
1) The average evoked potential of the cerebral cortex due to sciatic nerve stimulation was composed of N1, N2, Ng, P, N4 and N5 components. These components showed an inhibition in the form of a decrease in their amplitude following wearing of the contact lens.
2) Th e average evoked potential of the hippocampus due to sciatic nerve stimulation tended to be facilitated following wearing of the contact lens, that is, the HN1, HN2, HN3, HN4 and HN5 components generally had their amplitude increased.View full abstractDownload PDF (2635K) -

JOURNAL FREE ACCESSThe effects of the massive administration of corticosteroid on renal function during and after the extracorporeal circulation had been studied clinically on sixty patients undergoing open heart surgery who consisted of forty-five patients given dexamethasone 30 to 60 minutes before the extracorporeal circulation and fifteen patients without pdethxeaarmsa aye thcoasnotrnoel, and experimentally on ten mongrel dogs unde rgoing total body perfusion, and the following results had been obtained.
1) Dexamethasone, given in massive doses, enhanced th e renal function during and after the extracorpoeal circulation. Clinically and experimentally, the urinary output increased and experimentally, glomerular filtration rate and renal blood flow were satisfactorily maintained during and after perfusion by a large administration of dexamethasone.
2) One mg/Kg of dexamethasone may be an adequate dose, but the effect of dexamethasone on renal function by the administrated dosage may differ between children and adults, and its effect was more remarkably in children than in adults.
3) The increased urinary output continued until 24 hours after the extracorporeal circulation and a mutual correlation was demonstrated between the urinary volume and the excretion of urinary potassium in the patients given more than 1 mg/Kg of dexamethasone. The increased urinary volume was not due to water diuresis, but was due to solute diuresis associated with a rise of excreted potassium in urine. Judgi ng from these results, dexamethasone might act on the distal renal tubules.
4) No significant relationship between the plasma antidiuretic hormone level and the urinary output during and after perfusion was seen, and the antidiuretic hormone value during perfusion increased and it immediately after perfusion decreased irrespective of dexamethasone administration. Therefore, dexamethasone may have no effect on the plasma antidiuretic hormone.View full abstractDownload PDF (3042K) -
