These dangerous rises in venous pressure are generally coincident with a fall of systolic arterial pressure, although there may be no constant relation between the two. He also finds that with an increase of venous pressure the urinary output decreases. This, of course, shows venous stasis in the kidneys as well as a probable lowering of arterial pressure. Int.
We may be sure, then, that the ideal of ecclesiasticism is not solely responsible for the scientific stasis of the dark age. Indeed, there was another influence of a totally different character that is too patent to be overlooked the influence, namely, of the economic condition of western Europe during this period.
Admitted for sake of argument that such is the case, then disease either acute or chronic of one or more of the sinuses with the accompanying inflammatory reaction, congestion and stasis, will cause an increased amount of fluid to be taken care of by the lymph channels draining these sinuses.
The finger nails often show venous stasis. In these cases the blood pressure is subnormal, the pulse may be hardly perceptible, and there is none of the tension of the body from fear. The patient may be fearful, but lie is completely collapsed. Such an attack may occur suddenly in a heart that is perfectly compensating, or it may accompany general edemas and dropsies.
Except for a stasis of very long duration, there is no sensation of time. To Brion's consciousness, Ihjel flipped the switch off with a continuation of the same motion that had turned it on. The ship was unchanged, only outside of the port was the red-shot blankness of jump-space. "How do you feel?" Ihjel asked. Apparently the ship was wondering the same thing.
Now the zone of force, which is itself a fourth-order phenomenon, sets up a condition of stasis in the particles composing the ether. These particles are relatively so coarse, that rays and particles of the fifth order will pass through the fixed zone without retardation.
It has been shown by Wright of Boston, that the coloration is due to stasis from mechanical over-distension of the veins and capillaries; actual extravasation into the tissues is exceptional.
The true pathology of the elephantoid diseases may thus be briefly summarized: A parent filaria in a distant lymphatic prematurely expels her ova; these act as emboli to the nearest lymphatic glands, whence ensues stasis of lymph, regurgitation of lymph, and partial compensation by anastomoses of lymphatic vessels; this brings about hypertrophy of tissues, and may go on to lymphorrhoea or chyluria, according to the site of the obstructed lymphatics.
Evolution does not proceed by such vaults as this would imply. Celt, Goth, Hun, and Slav must undergo progressive development for many generations before the population of northern Europe can catch step with the classical Greek and prepare to march forward. That, perhaps, is one reason why we come to a period of stasis or retrogression when the time of classical activity is over.
We can thus understand how either emotional strain or acute or chronic infection may cause either exophthalmic goiter or cardiovascular disease; how chronic intestinal stasis with the resultant absorption of toxins may cause cardiovascular disease, neurasthenia, or goiter.
