Standard fermentations were performed as follows: A spore suspension was inoculated into 3 L of the following medium: sucrose, 3 per cent; corn steep liquor, 1 per cent; molasses, 0.1 per cent; NaCl, 0.05 per cent; and CaCO3, 0.4 per cent. The fermentations were carried out at 27 C in 5-L fermentors (Bartholomew, Karow and Sfat, 1950). After 36 hours, 100 ml of the culture fluid was transferred...

BACKGROUND With an increased use of magnetic resonance imaging, the indications for endoscopic retrograde cholangiopancreatography (ERCP) have changed. Consequently, the patterns and factors predictive of complications after ERCP performed during current routine clinical practice are not well known. METHODS A prospective multicentre cohort study was undertaken in 11 Norwegian hospitals. Compl...

The medical records of 179 patients were reviewed to identify complications related to the use of the halo external skeletal-fixation device. The complications that were identified included pin-loosening in 36 per cent of the patients, pin-site infection in 20 per cent, pressure sores under either a plastic vest or a plaster cast in 11 per cent, nerve injury in 2 per cent, dural penetration in ...

T h e prevalence of manic depressive illness the world over is generally believed to be aroimd 3-1/1000, whereas the period prevalence for all forms of depressions has been estimated at 3 per cent per annum in North American population (Lehmann, 1971). Hospital data from various centres in India have given conflicting findings. Generally tfie figures from North India have been consistently high...

The wide-spread distribution of trypsin inhibitors throughout the vegetable and animal kingdoms (1) makes elucidation of their physiological function of great interest. From this point of view, resistance to peptic digestion becomes an important property, since only an inhibitor resistant to pepsin is likely to produce any physiological effect when ingested by a normal animal. The soy bean inhi...

Data collected between 1993 and 1996 from two Scottish hill farms were used to assess the potential importance of predation by foxes as a cause of lamb mortality. Farm 1 was in Midlothian and farm 2 in West Perthshire. Overall lamb mortality rates from birth onwards were 10.2 per cent for farm 1 and 9.3 per cent for farm 2. Sixteen lambs were identified as killed by foxes on the two farms durin...

396 male patients with gonococcal urethritis were treated by one of three treatment schedules. Of 132 patients treated with 2.4 m.u. procaine penicillin plus 2 g. probenecid, 109 were followed. There were three (2.8 per cent) recurrences in the first week and none in the second. Of 132 patients treated with 2 g. ampicillin plus 2 g. probenecid, 112 were followed. There were four (3.6 per cent.)...

1. The foveal visual acuity of eleven subjects was studied in relation to illumination under normal atmospheric conditions and at simulated altitudes of 10,000 feet (14.3 per cent O(2)) and 18,000 feet (10.3 per cent O(2)). A mask was used to administer the desired mixtures of oxygen and nitrogen. At the end of each experiment, measurements were made while inhaling 100 per cent oxygen from a cy...

In a 12-month prospective study incorporating four neighbouring district general hospitals, 228 patients required a total of 236 admissions with intestinal obstruction. The aetiological factors included adhesions 75 (32 per cent), malignant disease 61 (26 per cent), strangulated hernias 59 (25 per cent), volvulus 10 (4 per cent), acquired megacolon 6 (3 per cent), pseudo-obstruction 4 (2 per ce...
