RESUMO
The clinical significance and potential of respiratory tests for diagnostics of Helicobacter pylori infection was estimated in 76 patients. Results of 13C and 14C-urease tests were in especially good agreement with those oh histological studies. The 13C-urease test should be preferred in the examination of both in-patients and out-patients whereas NH3-urease test is much inferior to 13C and 14C-urease tests in terms of informative value.

The formation of scar tissue always follows lumbar disc surgery and usually causes no difficulty. Reoperation may be necessary because of disc reherniation or because of the scar tissue itself. Reoperation is tedious and dangerous because of the presence of scar formation. Beginning in February 1975, the authors performed laminotomies in 107 dogs in an attempt to study the possibility of prevention of scar tissue formation about the dural sac and nerve roots. Gelfoam and Gelfilm were found to increase scar formation. Micropore tape and plastics such as polyethylene, mylar, and woven and smooth silastic were tried without complete success. Free fat grafts gave better protection than other substances, but it was found that pedicle grafts of fat gave more complete prevention of scar. The living pedicle fat grafts also prevented the usual closure of the laminotomy. The technique of pedicle fat grafts has also been used with success in 36 human patients to date.

Extensive development of the rough endoplasmic reticulum and comparatively less developed Golgi membranes were seen in the cells of chondrocyte clusters which had formed in the vicinity of cartilage defects produced by intra-articular papain and cortisone injections. These cells frequently showed myelin-like membranous figures. These figures were seen either close to the cell membrane, or between cells, or connected to the nuclear envelope or the endoplasmic reticulum. The hypothesis is advanced that the myelin figures are made from redundant material which was not used for membrane formation. Cortisone, which is known to interfere with mitochondrial function and general metabolic processes, could have been responsible for the deficiency in membrane differentiation and transfer. This investigation was supported by grants from the Orthopaedic Research and Education Foundation and from the Research Evaluation and Allocation Committee of the School of Medicine, Univeristy of California, San Francisco.
