Surgical management of primary hyperparathyroidism guided by double-phase Tc-99m-MIBI scintigraphy
Objective ::: The aim of this work was to study the clinicopathological features of cases with primary hyperparathyroidism (PHPT) referred to National Cancer Institute (NCI), Cairo University in the last six years and to study the role of nuclear medicine techniques in the initial diagnosis and preoperative localization directing surgical management of these cases. cases.
SDS-PAGE was used for establishing the genetic identity of sunflower hybrids and determining percentage genetic purity of F 1 hybrid seeds. The hybrids differed from each other in terms of the total number of protein bands, protein bands in three zones, thickness and intensity of protein bands; and likewise the aberrant were detected within a hybrid. The relative mobility of each protein band, Rm value, provided a basis to distinguish aberrant types within an F 1 hybrid. The hybrids studied differed in both specific and common Rm values, presumably due to the differences in helianthinins in the hybrids. SDS-PAGE and field grow-out test gave largely similar results. The possible use of SDS-PAGE technique in routine testing for determination of percentage genetic purity of sunflower hybrid seed lots for commerce is discussed.
