    Neurophysiological abnormalities in genuine female stress urinary incontinence (1988)

    Notes: Summary. Perineal sensory and motor function was investigated in 28 women with genuine stress incontinence of urine and compared with a matched control group. Electrosensitivity of the dorsal nerve of the clitoris and of the urethral mucosa was significantly diminished in these patients (eight measurements ‘insensitive’). Three different reflex latency measurements (dorsal nerve to external anal sphincter, dorsal nerve to urethral sphincter, urethral mucosa to external anal sphincter) were prolonged in incontinence (14 absent reflexes). Mean motor unit potential duration of the external anal sphincter was also prolonged, reflecting an early neuropathy. Anorectal manometry detected significantly weaker squeeze pressures in stress incontinence although other variables were unaffected.

    Ultraviolet photoionization in CO2 TEA lasers (1988)

    Notes: The factors affecting spark ultraviolet (UV) emission and transmission, photoionization, and photoelectron loss mechanisms in CO2 TEA laser gas mixtures have been investigated and compared with the results of other workers. We found two different sources of UV radiation: N2 and an unidentified emitter, postulated to be associated with ionized electrode material; C (from CO and CO2) appeared to have little effect. UV emission was directly proportional to the amount of stored electrical energy in the spark-discharge circuit and to the cube of the peak current produced by the discharge of this energy. The uniformity of preionization produced by two kinds of spark-free space and notched surface guided was examined and the free-space spark was found to be superior. Photoionization was found to be due to the presence of low ionization potential (IP) alkenes in unseeded and fresh gas mixtures and also to NO and NO2 in sealed devices—these were formed as a result of spark plasma reactions. The nature of the photoionization process in NO and C3H6 (an alkene) was investigated; both were ionized in a single-step process. The absorption coefficient for ionizing radiation in CO2 was measured in a gas mixture containing 9% N2 and a N2 free mixture and values of 1.3 and 1.9 cm−1 atm−1 were obtained. It is thought that this may be due to changes in the spark UV emission spectrum when N2 is present. The loss of photoelectrons by third body attachment to NO, NO2, and O2 was monitored and only the attachment to O2 was found to be significant. However, the oxides of N can play a dominant role in the subsequent negative ion reactions on a millisecond timescale.

    The role of fluctuations in spontaneous metamagnetism (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 64 (1988), S. 5633-5635

    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A Landau–Ginzburg Hamiltonian involving coupled sublattice magnetizations as order parameters for spontaneous metamagnets is studied. A brief review of the mean field results is followed by an analysis of the role of fluctuations which arise due to the inhomogeneity terms in the Hamiltonian. Using a Gaussian approach the specific heat contribution from the normal modes is studied neglecting mode-mode coupling. A non-Gaussian approach to the problem is also outlined. While for finite sizes specific heat shows no anomalies, in the thermodynamic limit classical exponents are recovered. The kinetics of the transition is described by the Euler–Lagrange equations for sublattice magnetizations which result in two nonlinearly coupled nonlinear Klein–Gordon equations. Special solutions obtained from a particular ansatz include solitons and elliptic waves whose physical interpretation is provided.

    Contact dermatitis in patients with leg ulcers (1988)

    Topics: Medicine
    Notes: 100 patients with leg ulcers were patch tested against a standard battery of allergens. The readings were carried out daily from the 2nd to the 7th days. 55 patients showed positive reactions to one or more allergens. 32% of positive reactions developed for the first time after 48 h and 11 % after 72 h. No single day or combination of two days gave 100% positive results. A single reading on the 4th day gave the highest number of positive reactions at 92%. The prevalence of positive patch tests was significantly higher in patients with surrounding eczema, and in patients with positive patch tests the ulcer duration was significantly longer than in those with negative patch tests. The total number of positive results in individuals increased linearly with the duration of the ulcer. Of allergens to which the ulcer was exposed, the occurrence of multiple sensitivity was significantly greater than predicted from the prevalence of individual sensitivities. However, there was no association between medicaments and metal sensitivity. This, together with the absence of an exponential rise in the number of allergens with the duration of ulcer, does not support the theory of systemic ampliative allergy.

    Histochemical studies on glycosaminoglycans of odontogenic cysts (1988)

    Notes: Histochemical examination of odontogenic cyst connective tissue has demonstrated that hyaluronic acid is the predominant glycosaminoglycan present with lesser amounts of the sulphated glycosaminoglycans. Mast cells were frequently observed in the connective tissue, particularly just beneath the epithelium and may be responsible for the enhanced staining for heparin observed in this area. Local tissue metabolism and inflammation will contribute to the release of glycosaminoglycans from connective tissue into the lumenal fluid. Staining of glycosaminoglycans was generally minimal in the epithelium, although hyaluronic acid and chondroitin sulphate were detected in goblet cells. Glycosaminoglycans previously demonstrated in cyst fluids are probably derived from several sources in the cyst and will be important in its expansile growth.

    AN UNUSUAL PHOSPHATIDYLINOSITOL TURNOVER PATHWAY IN NORADRENALINE-PERFUSED RAT HEARTS (1988)

    Notes: 1. The phosphatidylinositol turnover pathway has been studied in noradrenaline-perfused rat hearts using anion-exchange high performance liquid chromatography.2. The active calcium-releasing compound inositol-(1,4,5)trisphosphate was detected together with its degradation products inositol-(1,4)bisphosphate and inositol monophosphate. All these products increased in response to noradrenaline stimulation.3. At noradrenaline perfusion times from 5 s to 20 min there was no appearance of inositol-(1,3,4,5)tetrakisphosphate or its degradation products: inositol-(1,3,4)trisphosphate or inositol-(1,3) and (3,4)bisphosphates.4. These data suggest the absence of the inositol-(1,4,5)trisphosphate phosphorylation/dephosphorylation pathway in heart.

    ENDOTHELIUM-DEPENDENT INHIBITION OF SYMPATHETIC VASOCONSTRICTION BY FRUSEMIDE ADMINISTRATION TO RATS (1988)

    Notes: 1. Segments of the tail artery of the rat were cannulated at both ends and mounted in an organ bath filled with Krebs solution.2. Using an extracorporeal circuit, blood was pumped at a constant 2 ml/min from the carotid artery of anaesthetized rats to perfuse the segment of tail artery, and returned to the donor rat via the jugular vein.3. Peri-arterial electrical stimulation of the ex vivo blood perfused tail artery at 5 Hz produced vasoconstriction and an increase in perfusion pressure.4. The intravenous administration of frusemide 5 mg/kg to the donor rat resulted in an inhibition of the vasoconstrictor responses of the perfused tail artery segment. Diuresis-induced losses of volume and frusemide were prevented by a urinary bladder-venous shunt.5. Removal of the endothelium from the tail artery segment, by perfusion with dry gas for 4 min, prevented the vasoconstrictor-inhibitory effect of frusemide administration. Removal of the endothelium was confirmed histologically and by the absence of a vasodilator response to acetylcholine.6. On the basis of these and previous results it is concluded that parenteral frusemide administration releases an unidentified but non-prostanoid hormone from the kidney which produces an endothelium-dependent inhibition of sympathetic vascoconstriction.
