the acid-base status and arterial blood gas change with temperature variation. to determine the changes in arterial ph and pc02, arterial blood samples of 50 neonates with different clinical conditions were examined at temperatures of 35 to 42°c with an increment of 0.5° c, which resulted in two nonlinear equations with perfect fit on data. the temperature correction factors of these equations,...

Methods and Results-—A total of 116 hypertension patients and 54 healthy controls were enrolled in the investigation. Hypertensive patients were divided into 2 groups: the with arterial stiffness group (brachial-ankle pulse wave velocity [baPWV] ≥1400 cm/s; n=83) and the without arterial stiffness group (baPWV <1400 cm/s; n=33). A noninvasive measure of vascular stiffness was performed using pu...

conclusions it seems that there is no difference in the use of heparinized and normal saline solutions to prevent catheter occlusion of arterial and central venous pressure. patients and methods in the current randomized controlled trial, 100 patients, with an age range of 18 - 65 years of valve and coronary artery surgery were studied in rajaie heart center, tehran, iran. patients were randomi...

Acid-base alterations in Streptococcus pneumoniae infection were studied in 80 male albino rats. Hematocrit and concentrations of plasma electrolytes, glucose, and total protein were also measured. At 3-h intervals throughout a 27-h study, four control and four infected rats were anesthetized with ether, and blood samples were taken. Arterial blood pH, Po2, and hematocrit increased in the infec...

• In a recent study, measurements of lengths, diameters, and numbers of vessels contained in a peripheral vascular bed from distributing artery to arterial capillaries were made in the living animal. From the data, total crosssectional areas of the various portions of the arterial tree were calculated and compared with values from similar measurements of vessels in fixed tissue. In the living a...

Cardiac output was determined in dogs over a wide range of pressures before and after preclusion of compensatory reflex mechanisms. When the moderator reflexes are functional, total peripheral resistance increases markedly with moderate reductions in arterial pressure. When reflex alterations of vasomotor tone are obviated, pressure and flow usually vary proportionately as arterial pressure is ...

This case study reports a rare variation of the superior laryngeal artery (SLA), which is the principal arterial supply of the larynx. The knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. During routine dissection of an adult male cadaver, a rare arterial variation in the SLA was seen. In this case, the SLA passed through ...

PURPOSE To evaluate the therapeutic results and rate of organ preservation in patients with stage III or IV oral cancer treated with retrograde superselective intra-arterial chemotherapy and daily concurrent radiotherapy. MATERIALS AND METHODS One hundred and twelve patients with stage III and IV oral squamous cell carcinoma underwent intra-arterial chemoradiotherapy. Catheterization from the...
