Effects of inhaled plasminogen activator on the balance between coagulation and fibrinolysis in traumatized pigs.

A profibrinolytic state is normal in the alveoli, but this may change as a result of trauma, possibly leading to fibrin deposition, a characteristic of acute lung injury/acute respiratory distress syndrome. Therefore, the present study investigated in a double-blind, placebo-controlled manner the effect of severe trauma on the alveolar fibrinolytic/coagulation balance, and the effect here-upon of inhalation of single-chain urokinase plasminogen activator (scu-PA) in pigs. The study shows an increased concentration of scu-PA in the bronchoalveolar lavage fluid of the treated animals in association with an increased plasmin-dependent fibrinolytic activity without increased systemic fibrinolytic activity, the transient increase in the concentration of scu-PA in the plasma being minimal.

Activation of blood coagulation in pigs following lower limb gunshot trauma.

A standardized, quantifiable gunshot trauma to one hind leg of fourteen anaesthetized and sedated pigs was used to investigate the extent to which an isolated gunshot trauma causes activation of blood coagulation. The traumatized pigs were mechanically ventilated in intensive care for 48 h before they were euthanized. Blood samples were drawn at baseline (t = 0), 24, 27 and 48 h after trauma to examine the late effects on haemostasis.

Out-patient rehabilitation improves activities of daily living, quality of life and exercise tolerance in chronic obstructive pulmonary disease.

The purpose of this study was to investigate the effects on activities of daily living, quality of life, and exercise tolerance of a comprehensive out-patient rehabilitation programme for patients with moderate-to-severe chronic obstructive pulmonary disease. In this randomized and controlled trial, the main outcome measures were Activities of Daily Living (ADL) score, York Quality of Life Questionnaire (YQLQ) score, Chronic Respiratory Disease Questionnaire (CRDQ) score, 6 min walking distance (6MWD), forced expiratory volume in one second (FEV1), and forced vital capacity (FVC). The rehabilitation programme included physical training, occupational therapy, education, and smoking cessation therapy, and lasted for 12 weeks.

Treatment of herpes zoster with idoxuridine ointment, including a multivariate analysis of symptoms and signs.

A double-blind, random selection comparison was made of the therapeutic effects in acute herpes zoster of (A) 40% idoxuridine (IDU) dissolved in dimethyl sulphoxide (DMSO), or one of the following ointments: (B) a basis of polyethylene glycol, (C) a basis with 60% DMSO, (D) a basis with 5% IDU and 60% DMSO, and (E) a basis with 40% IDU and 60% DMSO. Each group comprised 20 patients. The patients were evaluated daily until skin healing and then at 1,3, and 6 months by registering 4 neurological signs, 5 clinical evaluations of skin pathology and 4 photographic evaluations of the skin lesions.
