Abstract: The extensive range of specificities of T-cell receptors is generated, as for immunoglobulins, by rearrangement of genetic information. Much valuable information about rearrangement processes has been inferred by comparing DNA from (monoclonal) lymphoid lines with germ-line DNA and, for B cells, from rearrangements in some Abelson murine leukaemia virus-transformed cell lines. However, because it is difficult to isolate and grow precursor populations, it has not proved possible to study rearrangements occurring in normal untransformed cells in vitro. Here we show that a single T-cell precursor colonizing an alymphoid thymus lobe in organ culture can generate multiple receptor beta-chain gene rearrangements. These observations provide unequivocal evidence for the intra-thymic diversification of the T-cell repertoire. They also offer the possibility of investigating rearrangement and its control in the clonal progeny of a single normal T-cell precursor without the perturbations involved in the use of viral transformation or the production of T-cell hybridomas.

Abstract: We assessed in ponies the adequacy of using rectal (Tre) rather than arterial temperature (Tar) under conditions common to ventilatory control experiments, i.e., CO2 breathing, thermal stress, and particularly exercise. We were interested in whether, and to what extent, Tar-Tre differences could lead to errors in arterial blood gas corrections. At control environmental temperatures (Ta) of 5 degrees C in the winter and 21 degrees C in the summer, Tar and Tre (37.1 degrees C) did not differ (P greater than 0.05). Elevating winter or summer Ta by 10-18 degrees C for 2-days or lowering summer Ta by 9 degrees C (2-days) did not change Tar or Tre (P greater than 0.05). Furthermore, elevating inspired PCO2 to 42 Torr for 15 min did not alter Tar or Tre from control (P greater than 0.05). During treadmill exercise, at 1.8 mph 5% grade, Tar and Tre did not change significantly (P greater than 0.05) from rest by 11 min of work. At 3 mph 5% grade, Tar increased progressively by 0.3 degrees C (P less than 0.05) while Tre tended to increase 0.1 degree C by 11 min. During moderate exercise at 6 mph 5% grade, Tar increased 0.9 degree C (P less than 0.05) while Tre increased 0.25 degree C (P less than 0.05). Finally, by 6 min of heavy exercise at 8 mph 20% grade, Tar increased 2 degrees C (P less than 0.05) while Tre increased 0.5 degree C (P less than 0.05). The Tar-Tre differences during the latter three work loads were statistically significant (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract: A series of 150 patients with histologically confirmed angiofibroma examined from 1945 through 1983 was studied to contrast treatment methods and surgical approaches. From 1945 to 1955, treatment consisted primarily of radiation. From 1955 through 1971, the primary method of treatment was surgical removal; the lateral rhinotomy approach was used to expose the tumor and its extensions in most cases. From 1971 through 1983, all tumors were removed surgically. Trends in diagnosis, treatment, and adjunctive therapy at a single institution were evaluated. Specifically, the trends considered were operative approaches, blood replacement with and without hypotensive anesthesia, adjunctive measures such as hormonal therapy or tumor embolization, mortality, and morbidity. Lateral rhinotomy provides wide exposure of and access to the nose, nasopharynx, paranasal sinuses, elements of the skull base, temporal fossa, and infratemporal fossa. Surgical treatment, specifically the lateral rhinotomy approach and its extensions, is recommended as the best method of managing angiofibroma in most patients.
