    Notes: Ventilatory sensitivity to carbon dioxide was measured in six healthy volunteers before, and at various times up to 20 hours after, administration of epidural buprenorphine 0.15 mg with a modified Read rebreathing technique. The carbon dioxide response curves were depressed in a time-dependent, prolonged and biphasic manner. Significant depression was seen in the intercept values at an end tidal carbon dioxide of 7.2 kPa. for mouth occlusion pressure (p 〈 0.01), tidal volume (p 〈 0.05) and minute ventilation (p 〈 0.05). A significant reduction of slope was obtained only for minute ventilation. Linear regression of respiratory rate changes during carbon dioxide stimulation, did not reach statistical significance. In conclusion, these data indicate that epidural buprenorphine, despite a high lipid solubility, causes respiratory depression to the same extent as epidural morphine. Surveillance of patients who receive epidural buprenorphine for postoperative pain relief is necessary.

    Notes: A case of reactive perforating collagenosis in an adult male patient with chronic renal failure. Pruritic, umbilicate papules, showing extrusion of collagen fibers through the epidermis were detected histopathologically. Electron microscopy showed absence of basal membrane beneath the perforation and collagen fibers with preserved periodicity passing through widened intercellular spaces with islands of cytoplasmic material.

    Notes: Abstract Five soldiers were injured by inhalation of hexite smoke (ZnCl2) during military training. Two soldiers, not wearing gas masks breathed hexite for 1 or 2 min, they slowly developed severe adult respiratory distress syndrome (ARDS) over the ensuing 2 weeks. This slow, progressive clinical course has not been previously described. In both patients, an increased plasma zinc concentration was measured 3 weeks after the incident. Intravenous and nebulized acetylcysteine increased the urinary excretion of zinc, and briefly decreased the plasma levels. In an attempt to arrest collagen deposition in the lungs, L-3,4 dehydroproline was administered. Both patients died of severe respiratory failure (25 and 32 days after inhalation). At autopsy diffuse microvascular obliteration, widespread occulusion of the pulmonary arteries and extensive interstitial and intra-alveolar fibrosis was observed. Three soldiers wearing ill fitting gas masks, immediately developed severe coughing and dyspnea. They improved, and 12 months after exposure their lung function tests were nearly normal, but they still had slight dyspnea on exercise.

    Notes: Abstract To study whether critically ill alcoholics were more sick and had a worse outcome than other patients treated in the intensive care unit, data were collected during the initial 24 h on 216 consecutive patients admitted to an intensive care unit. Twentysix patients (12%) met the criteria for alcohol abuse. The patients' chronic health 6 months prior to admission and the extent of physiological derangement (Acute Physiology Score and Chronic Health Evaluation (APACHE)) were recorded just as the type and amount of treatment (Therapeutic Intervention Scoring System (TISS)). Alcoholics were found to be significantly more sick and had a higher mortality (50% compared to 26%) than other critically ill patients. However, when analyzing the TISS points, no difference was found between the two groups. All survivors were, every third month up to 1 year after admission, asked to fill in a questionnaire indicating their level of activity. No differences were found between the two groups 1 year after admission, but the alcoholics had lost more time due to death. It is concluded that studies with larger number of patients will reveal whether alcogolics constitute a special category of patients with a different prognosis than other ICU patients.

    Notes: Summary Cardiac function was investigated by echocardiography in 24 short-term Type 1 diabetic patients with a mean diabetes duration of 7 years (range 4–14 years) during conditions of ordinary metabolic control. Compared to 24 age and sex matched normal control subjects, measurements of myocardial contractility as left ventricular fractional shortening and mean circumferential shortening velocity were increased by 12% and 20% respectively. Another 8 Type 1 diabetic patients were examined during conditions of poor (hyperglycaemia and ketosis) and good metabolic control. Following improved glycaemic control, left ventricular fractional shortening and mean circumferential shortening velocity decreased by 16% and 24% respectively. Our findings show that short-term Type 1 diabetes is associated with increased myocardial contractility. Furthermore, this condition is related to the state of metabolic control.

    Notes: Abstract This is one of a series of papers on the Askervein Hill Project. It presents results from the Askervein 1982 and 1983 experiments in the form of vertical profiles of mean wind and turbulence integral statistics at upwind reference locations and at two hilltop sites. The data were obtained from a variety of sensors including sonic, Gill UVW and cup anemometers mounted on 50, 30, 17 and 10 m towers and TALA kite systems. Comparisons with numerical-model predictions are discussed.

    Notes: Abstract This paper provides an overview of some aspects of atmospheric boundary-layer dispersion processes over homogeneous and complex terrain. Special emphasis is placed on a discussion of the boundarylayer scaling regimes over homogeneous terrain and the characteristics of the dispersion processes associated with each of these regimes. The paper points out that vertical concentration profiles usually deviate substantially from a Gaussian distribution. The mean flow and turbulence over a low hill is dealt with, and in the inner layer the turbulence levels are increased due to the mean flow speed-up. In the outer layer the turbulence is modified by the rapid distortion effect. In a middle layer the turbulence is reduced due to the effect of a hill-induced streamline curvature. The paper concludes that the flow perturbations introduced by large-scale hills and valleys invalidate the use of simple approximations for describing atmospheric dispersion processes, and that it is necessary to utilize the full set of equations of motion.

    Notes: Abstract A method is outlined for using genetic male sterility to screen for cytoplasmic-genetic sterility in barley. Since the method utilizes genetic male sterile plants as females, a very large number of crosses can be made. The critical cytoplasmic-genetic interaction will occur in the F1 generation, further minimizing time and effort required in the screening process. The method was put to test with materials from a breeding program. The desired cytoplasmic-genetic interaction was not observed. Since only ten male stocks were tested, it is suggested that further studies with stocks of more diverse origin might prove successful. {fx350-1}

    Notes: Most published “interaction measures” can produce misleading results and often do not measure the true closed-loop interaction. Therefore, closed-loop transmittances are defined mathematically as direct, parallel, disturbance, and interaction transfer functions and it is shown that the direct Nyquist array design method includes an excellent basis for interaction analysis.
