Repeated plasm exchanges were performed in a 44-year-old man with Goodpasture syndrome, also treated with cyclophosphamide and prednisone. Improvement was observed within 3 weeks of starting the protocol, and by the 76th week, endogenous creatinine clearance had increased from 30 to 56 ml/min/1.73 M2 and serum albumin from 2.7 to 3.7 g/dl. Prior treatment with immunosuppressive drugs had not significantly influenced circulating antibody levels. But sustained suppression of antibody was achieved after the plasma exchanges were begun, suggesting that physical removal of circulating antibody combined with antiproliferative drug treatment may be a useful way to control undesirable humoral immune responses.  相似文献

This paper describes the use of the interview technique as a valid and reliable instrument for predicting job placement and vocational success. The interviews of 144 blind adults were objectively and quantitatively scored, making full use of all responses elicited by the S. The results indicated that job success and vocational placement are significantly related to a number of variables tapped by the interview, such as perception of blindness, learned ways of dealing with tension, interpersonal interaction, and employment potential.

Mutations of the alpha1A calcium channel subunit have been shown to cause such human neurological diseases as familial hemiplegic migraine, episodic ataxia-2, and spinocerebellar ataxia 6 and also to cause the murine neurological phenotypes of tottering and leaner. The leaner phenotype is recessive and characterized by ataxia with cortical spike and wave discharges (similar to absence epilepsy in humans) and a gradual degeneration of cerebellar Purkinje and granule cells. The mutation responsible is a single-base substitution that produces truncation of the normal open reading frame beyond repeat IV and expression of a novel C-terminal sequence. Here, we have used whole-cell recordings to determine whether the leaner mutation alters calcium channel currents in cerebellar Purkinje cells, both because these cells are profoundly affected in leaner mice and because they normally express high levels of alpha1A. In Purkinje cells from normal mice, 82% of the whole-cell current was blocked by 100 nM omega-agatoxin-IVA. In Purkinje cells from homozygous leaner mice, this omega-agatoxin-IVA-sensitive current was 65% smaller than in control cells. Although attenuated, the omega-agatoxin-IVA-sensitive current in homozygous leaner cells had properties indistinguishable from that of normal Purkinje neurons. Additionally, the omega-agatoxin-IVA-insensitive current was unaffected in homozygous leaner mice. Thus, the leaner mutation selectively reduces P-type currents in Purkinje cells, and the alpha1A subunit and P-type current appear to be essential for normal cerebellar function.  相似文献

A group of "informal" caregivers, local people to whom residents turn for information and advice, was identified in the east Harlem community and enlisted in a two-month study. Results suggest that formal human services agencies and their intended clientele would benefit by increased efforts on the part of these institutions to locate and work with community caregivers.  相似文献

Cortisone, aldosterone or nialamide was administered to adrenalectomized or sham-operated rats for 7 days, and methamphetamine was injected 24 hrs after the last injection of these compounds. Stereotyped head movement and licking activity were scored 5 min, 30 min and 60 min after methamphetamine injection and, in parallel brain methamphetamine levels in similarly treated rats were measured 5 min, 30 min and 60 min after the methamphetamine injection. Adrenalectomy depressed stereotyped head movements but enhanced the brain amphetamine accumulation. Nialamide but not the hormones further increased the amphetamine accumulation in adrenalectomized rats. No drugs had any effect on the amphetamine-induced head movement suppressed by adrenalectomy.  相似文献
