Excerpt from The Journal of the Oklahoma State Medical Association, 1916, Vol. 9 Any transitory cause producing on the vascular system increased blood pressure may be spoken of as functional hypertension. The increase of tension due to excessive mental activity or physical exertion, as found m forcible inspiration in normal man, are physiological acts which force a large amount of blood to the heart and brain. Increase In the viscosity of the blood impedes the circulation of the blood througho the capillaries (russell), and hence high tension. Acute gastric and intestinal pain may cause hypertension (curschmann.) Nicotine, alcohol, ergot, adrenalin, pituitrin, hydrastine hydrochlorate and 'stypticin are among the drugs which cause increase in blood-pressure. Nicotine (and pyridine) is one of the most destructive agencies to constructive metabolism in the arteries of the brain and should be ranked with alcohol.' Toxic factors are found in eclampsia (h. Vasquez), gout, alimentary intoxication, bact'eremias and uremia. Psychical hypertension of great intensity is seen in fright, anger, sudden joy and great sorrow. Extreme high tension may accompany acute compression of the brain ln frac ture of the base of the skull, and m apoplexy. Acute cerebral anemia produces the same symptoms as cerebral compression, hence, high tension. Obstruction of the cerebral sinuses and veins may be due to pressure 011 the innominate or jugular veins, by a tumor or aneurysm, to suffocation and strangling, to excessive strain, to tricuspid insufficiency, to embolism, to thrombosis, to arterial and venous degeneration, to ulceration, to abscess, and to hemorrhage. Wein burger observed ln the case of a gardener of 36, an aneurysm and rupture of the vessels, and the basal arteries and aorta were sound.
