Since families have similar genes as well as similar environmen

2、ts, familial diseases could be due to shared genetic influences, to shared environmental factors, or to both. For some years, the role of oneenvironment factor commonly shared by families, namely dietary salt (i.e., sodium chloride), has been studied at Brookhaven National Laboratory. These studies

3、suggest that long excess salt intake can lead to high blood pressure in man and animals. Some individuals, however, and some rats consume large amounts of salt without developing high blood pressure. No matter how strictly all environmental factors were controlled in these experiments, some salt-fed

4、 animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death. These marked variations were interpreted to result from differences in genetic constitution.By mating long successive generations of those animals that failed to develop hypertensi

5、on from salt intake, a resistant strain (the R strain) has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly. In contrast, by mating only animals that quickly develop hypertension from salt, sensitive strain (the S strain) has also been

6、 developed.The availability of these two strains permits investigations possible. They provide a plausible laboratory model on which to investigate some clinical aspects of the human hypertension. More important, there might be the possibility of developing methods by which genetic susceptibility (敏

7、感性) of human beings to high blood pressure can be defined without waiting for its appearance.
