lactic acidosis and recovery of neuronal function following cerebral hypoxia in vitro.	the rat hippocampal slice preparation was used to study the combined effects of hypoxia and lactic acidosis on neuronal function. control slices were exposed to a standard hypoxic insult while being perfused with normal artificial cerebrospinal fluid (acsf). experimental slices were perfused with acsf containing 1.0, 2.0, 10.0 or 20.0 mm lactic acid, 30 min before and during the same standard hypoxic insult. following at 30-min recovery period the ability of these slices to respond to orthodromi ...	1988	3345436
the transducer characteristic of hair cells in the human ear: a possible objective measure.	we describe here a new kind of non-linear interaction between the responses to two simultaneously presented am tones. the interaction occurs before the level of binaural convergence, and can be explained in terms of the shape of the inner ear hair cell transducer function.	1988	3345444
c-h-ras and c-k-ras gene hypomethylation in the livers and hepatomas of rats fed methyl-deficient, amino acid-defined diets.	the extent of methylation of the c-h-ras and c-k-ras oncogenes was compared in neoplastic and preneoplastic livers of rats fed one of several methyl-deficient, amino acid-defined diets for 18 months, with or without a preceding initiating dose of diethylnitrosamine (den). the restriction endonucleases mspi, hpaii, hhai, paer71 and xhoi were used for studying the extent and pattern of dna methylation. the results indicated that both c-h-ras and c-k-ras oncogenes were hypomethylated in all dna sam ...	1988	3345576
merkel cell tumour of the face successfully treated with radical radiotherapy.	a case of merkel cell tumour of the face and its dramatic response to a course of radical radiotherapy is presented below. the patient has been free of recurrence for 18 months and has suffered minimal side-effects from the treatment. this suggests that radical radiotherapy, as opposed to the standard wide excision, may be the preferred first-line treatment for at least some of these rare, but highly malignant tumours.	2009	3345856

fc receptor-mediated phagocytosis occurs in macrophages at exceedingly low cytosolic ca2+ levels.	cytosolic free ca2+ ([ca2+]i) homeostasis was investigated in mouse peritoneal macrophages and in the macrophage-like cell line j774. [ca2+]i measurements were performed in both cells in suspension and cells in monolayers loaded with either quin2 or fura-2. resting [ca2+]i was 110-140 and 85-120 nm for cell suspensions and monolayers, respectively. there were no significant differences in [ca2+]i between the two macrophage populations whether quin2 or fura-2 were used as ca2+ indicators. additio ...	1988	3346321
