    Notes: Summary Twenty-four hours after a tetracycline injection, the unimpeded, and more rapidly erupting, mouse mandibular incisor contained 20% to 44% more tetracycline than the contralateral, uncut incisor. It was concluded that the increased tetracycline incorporation reflected a higher rate of mineralization associated with faster tooth formation in the unimpeded tooth. By measuring the amount of tetracycline which became incorporated at different times after an incisor was shortened, it was possible to investigate an early stage of the response of the incisor to cutting. A significant increase in the capacity of the tooth to incorporate tetracycline was detectable 4 h after shortening the tooth, and this was maximal after another 4 h.

    Notes: Abstract The potential importance of neuroleptic activity measures in the management of schizophrenia warrants attention to the methods for assessing neuroleptic bioactivity and stability of neuroleptic bioactivity over time. We have carried out measurements of serum neuroleptic and prolactin concentrations in 18 schizophrenic patients treated with haloperidol or thioridazine for up to 1 year. Serum neuroleptic levels were measurd by a radioreceptor assay using porcine striatum. The lower limit of sensitivity of the assay was 0.6 ng haloperidol/ml, the intra- and interassay coefficients of variation 3 and 9%, respectively. A linear correlation was observed between haloperidol dose (5–30 mg/d) and serum neuroleptic activity (r=0.706, P〈0.001) and a curvilinear relationship between thioridazine dose (50–600 mg/d) and serum neuroleptic activity in schizophrenic outpatients. There was a positive correlation between serum neuroleptic and prolactin concentrations for the patients taking haloperidol (r=0.620, P〈0.001) or thioridazine (r=0.542, P〈0.001). In patients taking a constant dose of haloperidol or thioridazine for up to 1 year serum neuroleptic activity remained stable, suggesting the absence of metabolic tolerance; the observation of a decrease of 38±16% (mean ± SD) in serum prolactin concentrations in patients treated with haloperidol but no prolactin decrease with thioridazine suggests that under certain neuroleptic treatment conditions a functional tolerance develops in the tuberoinfundibular dopamine system.
