An Artifact Of Liquid Emulsion Autoradiography

The localization of ³H-opiatcs in the myenteric plexus of the guinea pig ileum is subject to systematic artifact when stretch preparations of the myenteric plexus are dipped into liquid Kodak NTB-3 emulsion for autoradiography. The cause of the artifact was determined to be a discontinuous distribution, or retraction, of emulsion over plexuses. The apposition of frozen freeze-dried ilial sections to dried photographic emulsion avoids this source of error.     

A Case Of Severe Neuropat Hy Associated With Hypertriglyceridemia

ObjectiveTo describe a case of severe neuropathy associated with hypertriglyceridemia.MethodsWe describe the clinical and laboratory findings of the study patient and review the relevant literature.ResultsA 45-year-old woman presented to the emergency department with recurrent abdominal pain and severe peripheral neuropathy. Her laboratory data revealed elevated lipase and a very high triglyceride concentration (> 10 000 mg/dL), consistent with a diagnosis of recurrent hypertriglyceridemia-induced pancreatitis. Workup for peripheral neuropathy showed normal concentrations of thyrotropin, fasting blood glucose, vitamin B₁₂, and creatinine, as well as a normal hemoglobin A_1c level, serum protein electrophoresis, and urine protein electrophoresis. Rapid plasma reagin antibodies, antinuclear antibodies, and lyme antibodies were not detected. In the absence of other identifiable causes, hypertriglyceridemia was deemed the likely etiology of severe neuropathy in this patient.ConclusionsPeripheral nerve conduction abnormalities can be identified in patients with mild hypertriglyceridemia in the absence of symptoms. Early recognition and aggressive management of hypertriglyceridemia may prevent the complications of severe peripheral neuropathy.(Endocr Pract. 2008;14:1020-1022)     

An Examination Of Factors Related To The Parole Survival Of American Indians

Abstract

This paper examines the parole survival of American Indians and non-American Indians released from a Western state prison. In order to determine whether the parole outcome exists independent of the ethnicity of the parolee, six pre-prison, prison and post-prison experiences were statistically associated with the parole outcome. The analysis reveals that the parole survival of the offender is in large part independent of ethnicity. Since the objective measures, or the experiences of the offenders, fail to explain the differences in the parole survival rates, the research suggests that attention should be focused on the activities of judges, parole boards and the parole officers in the field, for they have a great deal of discretion in the determination of parole survival.
