In formerly study,the typical dose-response relationship was existed(χ~2=17.76,P<0.01)between frequency and prevalence in the natural village with schistosomiasis prevalence>10%; the identical dose-response relationship was existed(χ~2=11.08,P<0.01)between Index A and prevalence in the natural village with schistosomiasis prevalence<10%.
MTBE above 0.050 mmol/L caused greater DNA migration in cultured rat type Ⅱ pneumocytes and rat hepatocytes in vitro(P<0.05),and also with dose-effect relationship(r_ lung=0.967,r_ liver=0.963,P<0.05)).
Results The PC12 cells were exposed to lead acetate at varied concentrations for 24 hours, and the growth and proliferation of the cells are inhibited with various degrees, showing a dose-effect relationship. The IC_ 50 was detected to be (533.966±100.830) μmol/L.
Results Along with time,the inputting speed increased but accuracy decreased,and was positively correlated with TP,LF(r=0.851 and 0.827 respectively,P<0.05),showing a distinct dose-effect relationship.
There was significant difference in above results in the medium and high dosage groups compared with the negative control group(P<0 05 or P<0 01), and there was dose response relationship(r=-0 987,-0 895,-0 981,0 981,0 958 and 0 962,respectively,P<0 05) in these indexes.
[Results] The rat type Ⅱ lung cells were treated with extract of air pollutants of RTSCDG at a single concentration of 1 02,2 03,4 06,8 13mg/ml,increase in DNA cross links and DNA single strand breaks and the dose response relationship were found after treatment ( r cross links =0 981, r breaks =0 987, P <0 01).
The phytotoxicity variation is maximum in a moderately polluted plot, where both very high and very low pollution levels were observed, which determines a substantially nonlinear dose-effect relationship.
Effect of TCB stress on SOD activity in seedlings displayed a significant dose-effect relationship for 1-5 d of 50-200 μg · g-1 treatment.
Both of them showed some extent of dose-effect relationship.
The dose-effect relationship between the exposure to CS2 and the symptoms of nervous system was demonstrated.
The results showed that IFN-γ could reduce the expression of transforming growth factor beta receptor I in the fibroblasts with the following dose-effect relationship:Y=1937.5-134.2 Igx (r=-0.971,P>amp;lt;0.01).
A dose/response relationship with dothiepin was observed.

In these cases, a dose response relationship of the interferon effect was obvious.
The results suggest a role of the regulatory guanyl nucleotide-binding protein in diabetes leading to an increased dose response relationship of the hepatic adenylate cyclase system to glucagon.
The purpose of this study was to examine the dose response relationship of subcutaneous injections of pramlintide on gastric emptying and to determine whether administration of the drug before one meal has an impact on the subsequent meal.
Starting from the assumption that during infection the host has a certain hazard of becoming ill, a simple dose response relation for acute gastroenteritis is developed.

One microgram of ALPs per 106 tumor cells was effective, in some experiments a dose response relation was found for even lower concentrations.
CP-46,665 suppresed the colony formation of various human tumors with a slight dose response relation after 1 hr incubation and with a clear optimum (85% response rate) after continuous exposure in the higher dose range tested (10 μg/ml).
The dose response relation between injected ACH and potassium-liberation is of a different nature for innervated and denervated muscle.
