The surgical importance of the dermocartilaginous ligament of the nose.

The dermocartilaginous ligament of the nose, as first described by the senior author, has been shown to influence the equilibrium of the dorsum-tip relationship. In some noses, this is manifested by a residual convexity after routine rhinoplastic management of the osteocartilaginous structures. The anatomic findings are reported, and surgical considerations are analyzed. A system of classification based on the thickness of the ligament has been shown to be helpful in the intraoperative evaluation of this structure.

Body contouring.

Body contour surgery concerns the correction of diverse morphological abnormalities of the body which may occur due to various acquired and congenital etiologies. The concept of surgical body sculpting has achieved widespread recognition and acceptance because it safely alters such deformities yielding functionally aesthetic results. Several factors account for the current popularity of body contouring. Foremost among them, is the considerably increased exposure of the body which is seen in most modem cultures, particularly in warm climates. In no other period in the history of western civilization have men and women been so revealingly attired. In addition, today's competitive society strongly encourages the maintenance of a lean athletic body, as a symbol of good health, youth and vigor. The reality of achieving this physical ideal becomes increasingly less likely because of current sedentary lifestyles and dietary excesses. These factors combine to create a disturbing disequilibrium between an individual's desired condition and his actual state. Regular adherence to proper diet and exercise must be stressed, but unfortunately some of these deformities remain resistant to the most sincere of such efforts. Subsequently, there are increasingly greater numbers of people who seek surgical correction for specific abnormalities. Body contour surgery is also an important reconstructive tool in the correction of extremely lax skin in obese patients who have recently undergone dramatic weight loss.

RNA and protein synthesis in spontaneous rosette formation by T lymphocytes.

Formation of rosettes with sheep red blood cells (SRBC) by peripheral blood lymphocytes and thymocytes has been studied. Trypsinization of these cells abolishes the capacity to form SRBC-rosettes. The process of re-establishment of this capacity to form SRBC-rosettes, in vitro, has been shown by use of metabolic inhibitors to require transcription, translation, and protein synthesis. These observations are interpreted in terms of the T cell markers as the expression of a definitive process or step in lymphoid cell differentiation.
