Watchers in the night: an anthropological look at sleep disorders.

An anthropological point of view is introduced to explain the origin of sleep disorders. Four groups of sufferers are discussed: (1) Those that fail to maintain primary relationships; (2) those that feel increased vulnerability during the night; (3) those who have failed to separate or individuate; and (4) those who show a higher arousability than sound sleepers. A case example is offered for each group. A description of sleeping arrangements of the Kung San people of the Kalahari desert; speculations of the need for arousability in primitive society to prevent predators from attacking serve to bolster the view point. A theory that suggests that sleep disorders in children are caused by Western sleeping arrangements, encouraging mother and child to sleep apart, is challenged.

Adult agoraphobia and childhood separation anxiety: using children's literature to understand the link.

Separation-anxiety stories are frequent in children's literature and have eight characteristic elements. Peter Rabbit is used as an early and very simple example. A case study follows which illustrates the fear of separating from the family in an adult agoraphobic. The Wizard of Oz is presented as a more expanded version of a separation-anxiety story. A case study follows which illustrates a woman's difficulty with maturity and separation. A review of the literature is made in which studies are cited which indicate a history of childhood-separation problems in adult agoraphobics. Studies also show that panic disorder in these patients is often precipitated by losses and separations. Studies also show that agoraphobics may have poor problem-solving skills. Children's stories may serve as a guide to children toward mastery of separation fear. A case study follows of a man who developed a panic disorder while watching E.T. E.T. is presented as a separation-anxiety story for the late 1900s. The paper concludes with a brief review of children's separation-anxiety stories and how they reflect broad cultural changes.

OmpR and EnvZ are pleiotropic regulatory proteins: positive regulation of the tripeptide permease (tppB) of Salmonella typhimurium.

The tppB locus of Salmonella typhimurium encodes the anaerobically-induced tripeptide permease. We have demonstrated that expression of tppB requires the function of the ompR and envZ gene products, originally identified as positive regulatory proteins required for the osmotic regulation of porin expression. Significantly, tppB expression is not osmotically regulated. We have also identified three additional genes whose expression depends on OmpR. Thus OmpR and EnvZ serve a more general regulatory role than has previously been supposed. This study provides the first detailed genetic analysis of the ompB locus of S. typhimurium.

Salmonella and Erysipelothrix infection in swine: a laboratory summary.

The occurrence of salmonellas and Erysipelothrix rhusiopathiae in tissues of swine was determined by bacteriologic and fluorscent antibody examination of 5,297 specimens from herds investigated for hog cholera. Of the specimens examined, 35.5% were positive for salmonellas, 21.1% were positive for E rhusiopathiae, and 8.3% were positive for both salmonellas and E rhusiopathiae.
