Despite a 3-fold range in follicle area in the marmoset, no differences in absorption rates of paraquat, mannitol, water, and ethanol were observed between different body sites (Scoll et al., 1991). However, among the different species examined in this study, there was an 80-fold range in follicle area, which correlated with observed differences in the rate of mannitol and paraquat absorption. The authors concluded that this correlation was only possible with relatively slowly ab.sorbed le.st penetrants, such as paraquat and mannitol. Further work is needed to determine to what extent unique anatomical features at different body sites play a role in absorption and penetration of both lipophilic and hydrophilic pesticides. 

The wild diploid and tetraploid species of wheat possess much higher rates of flag leaf photosynthesis than the cultivated hexaploids (1) The high rates of photosynthesis per unit leaf area have been correlated with several morphological and anatomical traits (2>3). Attempts have also been made to correlate the in vitro electron-transport rates with leaf photosynthesis. Zelenskii et al (4) found that the chloroplasts of wild diploid species had 42 per cent higher rates of uncoupled Hill reaction as compared with cultivated hexaploid. This was later confirmed by Miginiac-Maslow et al (5). However,...

Thallium scanning with the aid of computer analysis segregates the images into anatomic regions and specifically localizes areas of dead or necrotic myocardial tissue. In conjunction with ECHO or SPECT, thallium scans can correlate areas of abnormal wall motion with areas of poor perfusion. Sensitivity and specificity of thallium scanning to detect IHD disease are comparable with those of ET (75% and 80%, respectively). When used in conjunction with exercise ECG, sensitivity increases to about 80%. Thallium scanning also can be used in conjunction with ET to allow detection of lower levels of ischemia than may be determined from ECG abnormalities or patient...
