A government agency's responsibility to the consumer.

The U.S. Department of Agriculture's Office of Agricultural Biotechnology developed a proactive stance for informing consumers about biotechnology in 1987.

[The early and subclinical forms of cerebrovascular pathology in patients with chronic ischemic heart disease].

The results of a cardioneurological follow-up enabled the authors to develop the principles of the angioneurological evaluation of patients with chronic coronary heart disease (CCHD). The survey covered 118 CCHD males aged 40-59 of functional class I and II. A differential complex of tests involving neuropathological and neuropsychological examinations, rheoencephalography with pharmacological and bicycle ergometry tests, biomicroscopy of bulbar conjunctiva allows early detection of subclinical and initial manifestations of cerebral circulatory failure (CCF) in CCHD patients.

[The prediction of the development of circulatory encephalopathy in hypertension patients with the initial manifestations of brain blood supply insufficiency].

The principal risk factors conducive to the development of cardiovascular diseases in young and middle-aged subjects with chronic cerebrovascular insufficiency due to Stage I or II essential hypertension were under study. Thirty-four male patients with the initial manifestations of inadequate blood supply to the brain (IMIBS), 35 male patients with stages I or II dyscirculatory encephalopathy (DE), and 32 and 33 female patients with the same conditions, respectively, were examined. Hypertensive cerebral crises were significantly more frequent in DE patients of both sexes than in IMIBS patients, and a tendency to a longer standing of arterial hypertension was observed in DE patients as against those with IMIBS.

[Status of cerebral hemodynamics during measured physical loading in healthy subjects and patients with cerebral atherosclerosis].

The authors analyzed the results of the rheoencephalographic examination of the cerebral hemodynamics under graded exercise (GE) in 42 normal subjects and 60 patients with cerebral atherosclerosis. All individuals were males aged 40-59 years. It was shown that an increase in the blood content of the brain in the process of GE in the patients with cerebral atherosclerosis was significantly lower than in the normal subjects.

[Physical work capacity among the early manifestations of cerebral atherosclerosis].

A bicycle ergometric study of 54 males, aged 40-59 years, suffering from atherosclerotic dyscirculatory encephalopathy of Stage I-II and of 57 age-matched healthy males showed a considerable decrease in exercise tolerance of the patients. The fall in their capacity for physical work was attended by an inadequate hemodynamic response toward exercise in the form of a faster increase of the heart rate and a greater elevation of the arterial pressure. It is pointed out that level of exercise and the nature in which it is ensured hemodynamically may serve as additional criteria in assessing the functional potentialities of the cardiovascular system in early manifestations of cerebral atherosclerosis.
