Syphilis of the Circulatory System
1 hough universally recognised as a very potent factor in the causation of certain wellknown diseases such as aneurysm, Stokes Adams' syndrome, certain forms of meningitis, hemiplegia, etc., syphilis of the circulatory system is not by any means universally understood by the medical profession. It is, therefore, a great pleasure to read the lucid exposition of the subject by Dr. Ivy Mackenzie, ...
متن کاملA closed circulatory system model.
The model to be described is a “closed” system, comprised of four principal components : a pump, an arterial capacitance, a peripheral resistance, and a venous capacitance. The pump is servo-controlled, such that “cardiac output” is a function of venous pressure (FrankStarling mechanism). Also, because the model is a closed system, the venous pressure is a function of the cardiac output. The mo...
متن کاملAntagonistic Effects of Suramin Against the Venom of Snake, Echis Carinatus, on the Circulatory System of Developing Chicken Embryos
Background: The snake, Echis carinatus, one of the most venomous snakes in Asia, possesses a deadly hemotoxic venom. It has been reported that suramin, an anti-trypansomiasis drug, can inhibit the toxic effects of some snake venoms. This study was conducted to evaluate the possible antagonistic effects of suramin against the hemorrhagic activity of the venom from an Iranian snake, Echis carinat...
متن کاملThe Physiological Response of the Circulatory System to Experimental Alterations
An abnormal communication, experimentally produced between the right and left ventricles, causes a deflection of part of the blood stream into the shorter pulmonary circuit. Proceeding pari passu with the increase in volume flow of blood through this shorter circuit, there occurs a gradual enlargement of the heart limited to that part of the circulatory system through which the deflected blood ...
متن کاملCerebral venous circulatory system evaluation by ultrasonography.
Venous system can be classified as pulmonary veins, systemic veins and venous sinuses that are present only within the skull. Cerebral venous system is divided into two main parts, the superficial and the deep system. The main assignment of veins is to carry away deoxygenated blood and other maleficient materials from the tissues towards the heart. Veins have thinner walls and larger lumina tha...
