Dose-response Relationship in Angiotensin Bioassay
Cardiovascular Research, 1968In the albino rat, pressor response to 1–6 ng valine-5-angiotensin II, aspartic β-amide is a function of the logarithmic transformation of the dose of the drug. The latter transformation should be used to delineate dose-response relationship during angiotensin bioassay.

In this chapter, experimental results concerning the quantitative relationship between the atmospheric concentrations of ozone and PAN and effects on higher plants will be described, documented, and evaluated. The goal is to establish the limits of impact by photochemical oxidants on vegetation as a basis for risk prognosis and to pave the way for ...

Dose—response relationship in clinical oncology
Cancer, 1984The relationship of dose (and dose rate) to response and toxicity in clinical oncology is reviewed. The concepts expressed by some authors in dose-response studies in animal and human systems are reviewed briefly. Dose rate and tactics of conducting clinical studies are reviewed for both radiotherapy and various types of chemotherapeutic treatment ...

One of the most powerful tools in the analysis of toxicological events is the description of the intensity of the exposure in terms of dose, dose rate, or concentration for a specified duration of exposure in relation to the frequency or intensity of the observed responses.

Dose-Response Relationships for Meningioma Radiosurgery
American Journal of Clinical Oncology, 2015Dose-response relationships for meningioma radiosurgery are poorly characterized. We evaluated determinants of local recurrence for meningiomas treated with Gamma Knife radiosurgery (GKRS), to guide future treatment approaches to optimize tumor control.A total of 101 consecutive patients (108 tumors) who underwent GKRS for benign, atypical, or ...

Assessment of a dose–response relationship of levetiracetam
European Journal of Neurology, 2006The aim of this study was to assess the relationship between levetiracetam dose and both efficacy and safety in adult patients with refractory partial epilepsy. Dose–response relationships for levetiracetam efficacy were evaluated using pooled data from three trials including adults with refractory partial epilepsy.

Dose-Response Relationship of a Uricosuric Diuretic [PDF]
, 1977 Hyperuricaemia is a common complication of diuretic use in man and its simple elimination as a side effect would be an advantage. The finding that the indanone diuretic, MK-196, was actually uricosuric in the chimpanzee (Fanelli et alii, 1974), was of potential importance to human therapeutics.

LEAD AND MORBIDITY: A DOSE-RESPONSE RELATIONSHIP
The Lancet, 1978Many laboratory tests have been recommended for monitoring factory workers exposed to lead. To select the most useful test the best predictor of selected measures of morbidity was sought. 639 lead-exposed workers in several factories were questioned about abdominal ache, constipation, and fatigue and were examined for hand tremot.

Dose-response relationship in skin sensitization
Food and Chemical Toxicology, 1994The dose-response relationship (challenge phase) of the skin sensitization response was investigated in previously sensitized Hartley guinea pigs. Larger numbers of animals were used per group at the lower doses so that statistically significant observations could be made.

Radiation dose-response relationships
2018Clinical radiobiology is a field of medical research concerned with the relationship between a given physical absorbed dose of radiation in the range used for cancer therapy and the resulting biological response in a human as well as with the factors that influence this relationship. What is seen in clinical practice is a broad range of doses where the
