- Five hospitalized patients in different stages of Alzheimer-type dementia were monitored by unstructured, direct observations during morning care. Orem's model of nursing as a compensation for the patient's lack of self-care capabilities was used as a frame of reference for an analysis of the behaviours of patients and nurses during morning care. A 12-step classification system was developed to be used as a guide to understand and determine abilities essential for performance of morning care for demented patients. The quantitative assessment showed that none of the patients was able to manage morning care independently, but there was a wide variation in their highest level of performance.

Impaired visual contrast sensitivity in epileptic patients treated with carbamazepine.

- Critical flicker fusion frequencies and visual contrast sensitivity were determined in 27 adult epileptic patients receiving carbamazepine monotherapy and in 24 healthy, drug-free control subjects. Flicker fusion thresholds were the same in patients and control subjects, whereas the contrast sensitivity was significantly reduced in the patient group at all spatial frequencies. There was a significant negative correlation between the plasma concentration of carbamazepine and the contrast sensitivity at 11.4 and 22.8 cycles per degree, indicating that the reduced contrast sensitivity was due to the drug therapy.

Abolition of the effect of cyclosporine on rat cardiac allograft rejection by the new immunomodulator LS-2616 (Linomide)

- The effect of the quinoline-3-carboxamide LS-2616 (Linomide), given alone or together with cyclosporine, was studied in the first set cardiac allograft transplantation model in the rat. PVG rat hearts were transplanted heterotopically to Wistar/Kyoto rat recipients on day 0. The recipients were given LS-2616 orally on day -1 to rejection and/or CsA orally on days 0-9. In untreated animals rejection occurred on days 8-9, as judged by the absence of palpable pulsations. Treatment with CsA (5 or 10 mg/kg) resulted in prolongation of graft survival to days 17-21, i.e., the rejection occurred 8-10 days after cessation of treatment. LS-2616 in a dose of 160 mg/kg did not in itself have any impact on graft survival, but when given in doses of 40 or 160 mg/kg simultaneously with CsA (10 mg/kg), the effect of CsA was totally abolished. Animals treated with LS-2616 together with CsA had slightly lower trough blood levels than those treated with CsA alone. This interaction with CsA pharmacokinetics does not explain the results, as doubling of the CsA dose to 20 mg/kg, which well compensated for the difference in blood levels, was not sufficient to reverse the effect of LS-2616. To our knowledge this is the first compound known to abolish the effect of CsA. The mechanism is unknown, but is is possible that studies on the interaction between these two drugs will shed further light on the molecular basis of their modes of action.

The enhancing effect of cyclosporine A and sulfasalazine on the prevention of rejection in rat cardiac allografts

- Sulfasalazine (SASP) has been used for many years as a disease-modifying agent in inflammatory bowel disease and in rheumatoid arthritis. However, its mode of action is not entirely clear. Evidence has been accumulated which indicates that its efficacy is due to an immunomodulatory effect. In the present communication, we report that SASP has an immunomodulatory capacity in an experimental rat cardiac allograft model. A combination of 100 mg/kg per day of SASP given orally until rejection and 10 mg/kg per day of cyclosporine A (CyA) given orally for 10 days resulted in a significantly increased graft survival time as compared to that in animals given CyA alone.

A two-colour immunofluorescence test with a monoclonal human proinsulin antibody improves the assay for islet cell antibodies

- The conventional indirect immunofluorescence assay for islet cell antibodies was compared with a two-colour immunofluorescent assay to detect both islet cell antibodies with fluorescein isothiocyanate-labeled rabbit anti-human IgG and pancreatic B cells with a monoclonal human proinsulin antibody and Texas red-labeled sheep anti-mouse IgG. Determinations of end-point titres showed a correlation between the new two-colour immunofluorescent assay and the conventional indirect immunofluorescent assay in 1) selected sera positive for islet cell antibodies and insulin autoantibodies rs = 0.93 (p less than 0.01) or for islet cell antibodies alone rs = 0.99 (p less than 0.005) and 2) sera from children or young adults with newly diagnosed Type 1 (insulin-dependent) diabetes rs = 0.95 (p less than 0.0001). No interference between the monoclonal human proinsulin antibodies and islet cell antibodies with or without insulin autoantibodies or between the two second fluorescent antibodies was detected. It is concluded that the two-colour immunofluorescence assay is advantageous since it is possible to mix the reagents to avoid a more time-consuming and technically complicated assay, the presence of B cells can be confirmed in each section to permit detection of B cell cytoplasmic antibodies and microscopic evaluation is easier and more accurate, particularly in islet cell antibody negative samples.
