The ability of 4CMB to induce repair phenomena has been investigated in 3 types of assay. No significant unscheduled DNA synthesis or repair replication was found, although the compound gave a weakly positive dose-related response in strand-break assays, with 250 microgram/ml producing significant amounts of strand breaks. These data indicate that 4CMB is a weakly genotoxic agent.

The modified clove hitch: a technique to maintain endotracheal tube position in the intubated patient.

We describe the technique of using a modified clove hitch made of nasal cannula tubing as a means of insuring the position and security of an endotracheal tube in the intubated patient. Our experience indicates that this tie works well in both the prehospital and emergency department settings. We suggest that the modified clove hitch is a valuable adjunct to emergency airway management.

Anger of African American women in the south.

In this existential-phenomenological investigation middle-class African American women (n = 9) in the Southern United States were interviewed about their experience of anger in daily life. The purpose of the study was to examine what African American women's anger is about, what it means, and how it is experienced. Transcribed interviews were analyzed using a hermeneutic process. The thematic structure of African American women's anger comprises three main elements that stand out as figural: power, control, and respect. These figural elements can be understood only when seen against the ground of a racist Southern culture that produces pervasive mistrust. These findings are of importance to clinicians, who cannot deliver culturally competent interventions to African American female clients without a clear understanding of the complexity and meaning of their anger experience.

Effect of sodium intake on intraerythrocyte sodium concentration in normotensive subjects and patients with untreated mild hypertension.

The effect of changing sodium intake for 2 weeks was studied. Twelve normotensive subjects and five patients with mild essential hypertension were given two different levels of sodium intake for 2 weeks. Overall there was no significant rise in blood pressure but all patients with hypertension had a rise in blood pressure as they went from a low to a high sodium intake. Plasma sodium was not altered but red cell sodium concentration was higher on the high sodium intake. This effect was observed in both normotensive and hypertensive people. Alterations observed in cell sodium concentration provide support for the hypothesis that increased dietary intake of sodium may induce hypertension by causing changes in cellular transport systems.
