Serum lipoproteins of diabetic rats fed a high cholesterol diet.

Feeding a diet containing 2% cholesterol and 1% cholic acid (wt/wt) to rats made diabetic by administration of streptozotocin (45 mg/kg) produced marked hypercholesterolemia characterized by high concentrations of very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL) and a reduction in concentration of high density lipoproteins (HDL). The VLDL was unique in that it contained apo A-I and apo A-IV in addition to its usual complement of apoproteins: apo B, apo E, and the C apoproteins. IDL had a similar apoprotein composition. The HDL from these rats was deficient in apo E. Nondiabetic rats fed the same diet exhibited similar qualitative changes in lipoprotein concentration and composition but with lesser increases in VLDL and IDL concentrations. The altered apoprotein composition suggested that the hyperlipoproteinemia associated with cholesterol feeding in the rat is due to an inadequate rate of removal of lipoproteins of intestinal origin, and that this is greatly exacerbated by diabetes.

Mucocele-like changes in Bartholin's glands.

Two cases are described in which changes identical to those of oral mucocele occurred in Bartholin's glands. The histopathology, histochemistry, and pathogenesis are discussed.

Benign osteoblastoma of the ethmoid bone. Report of a case.

The second reported case of benign osteoblastoma of the ethmoid bone, in a 13-year-old boy, is described, with emphasis on clinical, radiographic and pathologic features. The characteristics of benign osteoblastoma are briefly elucidated.

Forgiveness as an intervention goal with incest survivors.

An intervention, with forgiveness toward their abuser as the goal, was implemented with 12 female incest survivors. The women, from a midwestern city, were 24 to 54 years old, and all were Caucasian. A yoked, randomized experimental and control group design was used. The participants were randomly assigned to an experimental group (receiving the forgiveness intervention immediately) or a waiting-list control group (receiving the intervention when their matched experimental counterpart finished the intervention). Each participant met individually with the intervener once per week. The average length of the intervention for the 12 participants was 14.3 months. A process model of forgiveness was used as the focus of intervention. Dependent variables included forgiveness, self-esteem, hope, psychological depression, and state-trait anxiety scales. After the intervention, the experimental group gained more than the control group in forgiveness and hope and decreased significantly more than the control group in anxiety and depression. When the control group then began the program they showed similar change patterns to the above, as well as in self-esteem improvement.
