Naturally enough, one turns to the records again to see if the blood-pressure of these patients was low, as would be expected with a poor adrenalin supply. Unfortunately record was made of the blood-pressure in only two cases, in both of which the reading was 110 m.m. Two such isolated observations mean, of course, nothing whatever.
Well, here he was, his soul manifestly all stirred up and his blood-pressure at a far higher figure than his doctor would have approved of, and the matter would have to be opened all over again. "Now then!" said the stout young man. George regarded him with a critical and unfriendly eye. He disliked this fatty degeneration excessively.
If the hemorrhage be long continued and the blood-pressure be low, there will be a permanent loss of some of the brain-cells. This explains why an individual who has suffered from a prolonged hemorrhage will never again be restored to his original powers. Drugs.
Even if a clot does form, when the blood-pressure rises it is readily displaced, leading to reactionary hæmorrhage. Should the wound become infected, secondary hæmorrhage is specially liable to occur.
Fainting, vomiting, urination, defæcation have been noted as occurring in young men after a first coitus. Epilepsy has been not infrequently recorded. Lesions of various organs, even rupture of the spleen, have sometimes taken place. In men of mature age the arteries have at times been unable to resist the high blood-pressure, and cerebral hæmorrhage with paralysis has occurred.
When the atmosphere is hot, there is a relaxation of the vessels of the skin, with a more than ordinary flow of blood, which is thus withdrawn from the deeper organs. The blood-pressure in the kidneys is not only diminished, but the total quantity passing through them in a given time is much lessened.
This is indicated, so far as the very marked increase of blood-pressure is concerned, by some observations made by Vaschide and Vurpas with the sphygmanometer on a lady under the influence of sexual excitement. In this case there was a relationship of sympathy and friendly tenderness between the experimenter and the subject, Madame X, aged 25.
On the other hand, owing to the lower blood-pressure the outflow goes on more slowly, and the gradually increasing pressure produced by the extravasated blood is usually sufficient to arrest the hæmorrhage before it becomes serious. As an aid in diagnosing the source of the bleeding, it should be remembered that the rupture of a vein does not affect the pulsation in the limb beyond.
In each instance, morphologic changes in the cells of all parts of the brain were found, but it required much more trauma to produce brain-cell changes in animals whose blood-pressure was kept at the normal level than in the animals whose blood-pressure was allowed to take a downward course.
With regard to the relationship of detumescence to the blood-pressure Haig remarks: "I think that as the sexual act produces low and falling blood-pressure, it will of necessity relieve conditions which are due to high and rising blood-pressure, such, for instance, as mental depression and bad temper; and, unless my observation deceives me, we have here a connection between conditions of high blood-pressure, with mental and bodily depression, and the act of masturbation, for this act will relieve those conditions, and will tend to be practiced for this purpose."
