Estimation of body fat in caucasian and Polynesian women from anthropometric measurements.
Girth measurements provide a simple method for estimation of total body fat that can be used over a wide range of percentage body fat (%BF). Well-established equations for determining %BF from girth measurements were applied to 42 Caucasian and 40 Polynesian women. %BF was determined from total body water measurement using oxygen-18 dilution. The relationship between the criterion measurement of %BF and that calculated from girth measurements differed significantly between the two ethnic groups. Assessment of body fat using girth measurements should use ethnicity-specific equations.
Renovating and refurbishing the field experience structures for novice teachers.
Teacher education at both the preservice and the inservice level has been criticized for not adequately preparing teachers for the demands and challenges in the classrooms of today, or for the future. This article describes a federally funded project awarded through the Office of Special Education Programs. The intended outcome was to improve the knowledge and application of professional skills and competencies for both preservice teachers (student teachers) and inservice teachers (supervising master teachers) through continuous, focused staff development, reflection, discussion, and coaching. The project focused attention on three related issues: (a) the role and training of the supervising and/or master teacher, (b) better partnerships between teacher preparation programs and the public schools, and (c) the effects of school structure on teachers' continued professional growth. This article describes the program planning, goals, activities, components, and impact of this personnel preparation project.
Discrepant cortisol values: comparison of radioimmunoassay and competitive protein binding technics.
Radioimmunoassays are expected to yield values representing the antigen, i.e., insulin, growth, cortisol, etc. employed in producing the antibody. However, in a recent study of a synthetic ACTH which involved the measurement of cortisol levels (1), we found that above 20gamma%, the radioimmunoassay (RIA) yields cortisol values distinctly above those obtained with the competitive protein binding (CPB) technic. We now suggest a possible explanation for this discrepancy and have calculated a correction factor.
Comparisons of synthetic 1-18 ACTH (Organon 2001) and 1-39 ACTH of animal origin in human subjects.
The studies in human subjects herein reported provide data on the relative effects of 1-18 ACTH (Organon 2001) and commercial 1-39 ACTH of animal origin on plasma cortisol, serum non-esterified fatty acids, and certain urinary steroids.

Serum calcitonin in thyroid disorders and in pheochromocytoma kindred.
Serum calcitonin was determined by RIA in 59 healthy subjects (Group 1), 49 randomly selected patients with treated or untreated thyroid disorders (Group 2), and in 12 kindred of a pheochromocytoma index case (Group 3). Although most subjects in Group 2 had normal calcitonin levels, there were significant (p less than 0.001) differences between all three groups. Of the five patients in Group 2 with high serum calcitonin, one had medullary cancer of the thyroid, one had multiple endocrine neoplasia, one had acromegaly, and two remained undiagnosed. Increased serum calcitonin levels were also found in seven of 12 normotensive relatives of a patient with pheochromocytoma. It is therefore concluded that high serum calcitonin levels in patients with thyroid disorders strongly suggest the presence of C-cell neoplasia or medullary cancer of the thyroid.
