Pseudocysts of the adrenal glands in newborn infants

With diagnostic aims the author used direct laryngeal tomography in patients with median stenosis of the larynx. Tomography made it possible to define the width of the lumen of the sumplica area. Depending on the change of the subplica area the author varied the extent of surgical intervention. He used the extralaryngeal method of vocal plica laterification in all patients. With narrow subglottis he practiced complete mobilization of the elastic cone and its subsequent laterification; with wide subglottis he mobilized only the uper edge of the elastic cone. He succeeded in obtaining good functional results concerning respiration in all patients.     

Formation of ectopic stimulation in the heart under the action of aconitine. I. The dynamics of input and output membrane currents

Rapid sodium and slow input and output currents were studied by the double saccharose bridge method on isolated atrial trabeculae of Rana ridibunda under the effect of aconitin (100 mg/l). It is shown that the ptroperties of rapid sodium channels change under the effect of aconitin. As the result of this, activation of the input sodium current begins at potentials which are close to the rest potential, the maximum value of sodium conduction reduces, while the reverse potential for sodium current is shifted in the direction of lower potentials. Despite the effect of aconitin, the sodium current is blocked by tetrodotoxin (10-6M). Aconitin causes reversible reduction of the input calcium current but has no effect on the output current.     

Association of crescentic glomerulonephritis with membranous glomerulonephropathy: a report of three cases

Association of membranous glomerulonephropathy with crescentic glomerulonephritis is apparently extremely rare. We report three patients who had this combination. One patient had biopsy-proven membranous glomerulonephropathy thirteen months prior to sudden and rapid decline in renal function necessitating hemodialysis. A repeat renal biopsy showed a superimposed crescentic nephritis and antiglomerular (GBM) antibodies were demonstrable in the serum. A second patient had proteinuria of unknown duration and then developed renal failure. Renal biopsy showed crescentic nephritis with a fine granular glomerular immunofluorescence for IgG typical of membranous glomerulonephropathy. Anti-GBM antibodies were present in this patient's serum. The third patient presented with acute renal failure of moderate severity. A renal biopsy revealed crescentic nephritis, granular deposits of immunoglobulins, and epimembranous electron-dense deposits typical of membranous glomerulonephropathy. Although his creatinine clearance improved spontaneously, nephrotic syndrome has persisted and a repeat renal biopsy showed a progression of the membranous glomerulonephropathy with the disappearance of the crescentic lesions. The reason for this peculiar association of membranous glomerulonephropathy and crescentic glomerulonephritis is unclear. It is possible that deposition of immune-complexes along glomerular basement membrane may render the glomerulus more susceptible to additional injury from a variety of other agents. Alternatively, depostis formed in one disease could initiate release of normal or altered basement membrane material and lead to formation of anti-GBM antibodies and subsequent development.
