Discharge planning strategies for acutely homeless inpatients.

Medical and psychiatric inpatients who become unexpectedly homeless during the course of the hospital stay present an extremely complex and time-consuming challenge to social work staff. The sudden shift from domiciled to undomiciled status creates a crisis for both the patient and the institution. Unanticipated homelessness among inpatients is usually associated with multiple high-risk factors which contribute to the rejection of such patients by numerous community facilities and services.

Properties of purified actin depolymerizing factor from chick brain.

Actin depolymerizing factor (ADF) from 19-day embryonic chick brains has been purified to greater than 98% homogeneity with a yield of 7.2 mg/100 g of brain. Quantitative immunoblotting with a monospecific antibody to ADF indicated that ADF comprises 0.

Inhibition of deoxyribonuclease I activity by actin covalently cross-linked to chick brain actin depolymerizing factor through exposed sulfhydryls.

All but one of the six free sulfhydryl groups of chick brain actin depolymerizing factor (ADF) are protected from modification when ADF forms a 1:1 complex with actin. This exposed sulfhydryl can be cross-linked to cys 374 of actin with N,N'-phenylenedimaleimide. The cross-linked complex inhibits the hydrolytic activity of pancreatic deoxyribonuclease (DNase I) to an identical extent as both the untreated complex and an equivalent amount of free actin.

Posterior urethral obstruction. Prenatal sonographic findings and clinical outcome in fourteen cases.

Fourteen cases of fetal urethral obstruction were reviewed retrospectively. The purpose of this study was to emphasize the following: 1) prenatal sonographic findings: 2) clinical outcome: and 3) associated congenital anomalies. Decreased amniotic fluid volume complicated 12 pregnancies (86%).

MR imaging of heterotopic gray matter.

Magnetic resonance imaging is the current method of choice to diagnose heterotopic gray matter and associated cerebral malformations. We report a case of an epileptic child in whom heterotopic gray matter is present without any associated ventricular distortion.

Acetylcholine-synthesizing amacrine cells: identification and selective staining by using radioautography and fluorescent markers.

The fluorescent DNA stain 4,6,diamidino-2-phenylindole (DAPI) was applied to the cut axons of the rabbit optic tract, from which it was retrogradely transported to the retinal ganglion cell bodies. The labelled retinas were isolated from the eye and maintained in vitro in the presence of [3H]choline. They were then quick-frozen, freeze-dried, vacuum-embedded, and radioautographed on dry emulsion for identification of the acetylcholine-synthesizing cells.

Helping behavior of females: effects of stress and commonality of fate.

In a design replication of Dovidio and Morris' study, the effects of stress and commonality of fate on helping behavior were examined. Ss were randomly assigned to one of four conditions: high stress/common fate (n = 15), high stress/dissimilar fate (n = 15), or low stress/common fate (n = 15), or low stress/dissimilar fate (n = 15). While the initial study involved male Ss, the present study involved females in order to assess the generality of the original findings.

Respiratory symptoms and pulmonary function of welders in the engineering industry.

We have studied respiratory symptoms, smoking habits, chest radiographs, sickness absence, and pulmonary function among 258 welders and an equal number of matched control subjects in three engineering factories. Welders who smoked had a higher frequency of chronic phlegm production than control subjects but there was no difference in cough or dyspnoea. The frequency of abnormality on chest radiographs was low and similar in welders and controls.

Acetylcholine synthesis by displaced amacrine cells.

The ganglion cell layer of the rabbit retina contains neurons that synthesize acetylcholine. To identify these neurons, the ganglion cells were labeled by retrograde transport of a fluorescent dye, and the acetylcholine-synthesizing cells of the same retinas were labeled by exposing the tissue to tritiated choline. Autoradiographs inspected by fluorescence microscopy showed that tritiated acetylcholine and the dye accumulated in different cells.

Normal values of transfer factor and transfer coefficients in healthy males and females.

A population study was performed to obtain local normal values of the transfer factor for a respiratory laboratory providing a routine hospital service. Statistical analysis of the results obtained showed similar results to those of previous investigators for the transfer factor and alveolar volume. The transfer factor was found to be dependent on height, age and sex, while the alveolar volume depended only upon height and sex.

An assessment of the place of follow-up pulmonary tuberculosis.

I n 1971--4 forty-four patients were found to have drug-susceptible tubercle bacilli in their sputum more than one year after a previous positive result. Comparison of their case records with those of 45 controls showed that inadequate chemotherapy was by far the most important cause of relapse. Most patients who have had adequate chemotherapy for pulmonary tuberculosis should be discharged.
