background and objective: nitric oxide (no) plays a role in thermoregulation and growth of protozoa. this work aimed to add the molecule no in physiology of protozoa in contact with abused narcotic substances. materials and methods: a sedative drug, morphine, was infused into a cell chamber containing paramecia . the cell response to the drug was recorded promptly after drug infusion using a po...

A functional aspect of the vascular system is defined as physiology, which covers mostly cardiovascular, cerebrovascular, renovascular and pulmonary systems. Most functions with perfect homeostasis under coverage haemodynamics. This haemodynamics maintains a steady relationship between intravascular pressure (P), overall resistance (R) circulatory flow (F). To explore more unknown facts physiol...

fluctuations in salinity impose stress on the physiology of the exposed fish population and can modify their structure. it has been noted that changes in blood characteristics and plasma levels serve as the primary link between environmental change and physiological response (mccormick, 2001). ninety healthy adult cyprinuscarpio (c. carpio) were randomly divided into five groups and kept in sal...
