1. CAPRINOS FUNDADORES TRANSGÊNICOS PARA O FATOR ESTIMULANTE DE COLÔNIAS DE GRANULÓCITOS HUMANO (hG-CSF): PARÂMETROS LEUCOCITÁRIOS E BIOQUÍMICOS ATÉ OS 285 DIAS DE IDADE / TRANSGENIC GOATS FOR FOUNDERS stimulating factor human granulocyte colony (hG-CSF): Leukocyte AND BIOCHEMICAL PARAMETERS TO THE 285 DAYS OF AGE
Human granulocyte colony-stimulating factor (hG-CSF) has been used as a hematopoietic growth factor due to its efficacy against neutropenia and chemotherapy-induced leucopenia. This project was approved by the Ethics Committee for Animal Use (CEUA-UECE, n 12/2005) and the National Technical Commission on Biosafety (CTNBIO, CQB n 0228/2006). Our group obtaine

2. Infecção na monitoração intraventricular da pressão intracraniana com drenagem contínua do líquido cefalorraquiano. / Infection in the intraventricular monitoring of the intracranial pressure with continuous drainage of cerebrospinal fluid.
Intraventricular monitoring of the intracranial pressure (ICP) with continuous drainage of cerebrospinal fluid (CSF) is already a widespread procedure in neurosurgical practice and considered as of great diagnostic, therapeutic and prognostic importance due to its precision. However, as it is an invasive method, it presents a potential risk of complications,

3. Hemodynamic effects of elevated cerebrospinal fluid pressure: alterations with adrenergic blockade
The cardiovascular effects of elevated cerebrospinal fluid (CSF) pressure were studied in 18 dogs, 6 in a control group, 6 after alpha adrenergic blockade, and 6 after beta adrenergic blockade. Vascular pressures did not change until CSF pressure was increased from 100 mm Hg to 200 mm Hg.

4. Role of Cerebrospinal Fluid [H+] in Ventilatory Deacclimatization from Chronic Hypoxia
Once ventilatory acclimatization begins in sea level residents sojourning at high altitude, abrupt restoration of normal oxygen tensions will not restore ventilation to normal. We have investigated the role of cerebrospinal fluid (CSF) [H+] in this sustained hyperventilation by measuring CSF acid-base status in seven men (lumbar) and five ponies (cisternal)

5. Cerebrospinal fluid outflow resistance in rabbits with experimental meningitis. Alterations with penicillin and methylprednisolone.
Acute bacterial meningitis may be associated with increased intracranial pressure, neurological sequelae such as communicating hydrocephalus, and a slow response to antibiotic therapy. Alterations in cerebrospinal hydrodynamics are at least partially responsible for these complications. Constant, low-flow short-duration manometric infusion studies through a

6. Ventilatory Acclimatization to Moderate Hypoxemia in Man: THE ROLE OF SPINAL FLUID [H+]
This study has assessed the regulation of arterial blood and cerebrospinal fluid (CSF) pH and thereby their contribution to the control of breathing in normal man during various stages of ventilatory acclimatization to 3,100 m altitude. CSF acid-base status was determined: (a) from measurements of lumbar spinal fluid during steady-state conditions of chronic

7. Granulocyte-macrophage colony-stimulating factor-induced arteriogenesis reduces energy failure in hemodynamic stroke
Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a powerful arteriogenic factor in the hypoperfused rat brain. To test the pathophysiological relevance of this response, the influence of GM-CSF on brain energy state was investigated in a model of hemodynamic stroke. Sprague-Dawley rats were submitted to three-vessel (bilateral vertebral and unila

8. Cerebrospinal fluid pulse pressure and intracranial volume-pressure relationships.
In six anaesthetised and ventilated dogs the CSF pulse pressure was compared with the volume-pressure response (VPR) during continuous inflation of an extradural balloon. Both pulse pressure and VPR increased linearly with the ventricular fluid pressure (VFP) up to a mean VFP of 60 mmHg. At this pressure a breakpoint occurred above which the CSF pulse pressu

9. Non-invasive measurement of intracranial pressure in the newborn and the infant: the Rotterdam teletransducer.
Knowledge of intracranial pressure may be important in many clinical situations in neonates and young infants. The best way to obtain this information would be a non-traumatic procedure. In order to test the reliability of a new fontanometer, the Rotterdam teletransducer, 25 simultaneous measurements of cerebrospinal fluid (CSF) pressure and anterior fontane

10. Cardiovascular responses to static exercise in conscious cats: effects of intracerebroventricular injection of clonidine.
1. Static exercise elicits increases in arterial blood pressure and heart rate (HR) in humans and conscious animals. In this study, the effects of intracerebroventricular (I.C.V.) administration of clonidine, an alpha 2-adrenergic agonist, on these cardiovascular responses were investigated using conscious cats. Four cats were operantly trained to extend a f

11. Cerebral circulatory and metabolic effects of hypotension produced by deep halothane anaesthesia
Hypotension to a mean blood pressure of 33 mmHg for periods of 70 to 187 minutes was induced by increasing the inspired halothane concentration in 11 baboons which were already anaesthetized with 0·5% halothane, nitrous oxide, and oxygen. During hypotension, cerebral blood flow, measured by Xenon clearance and by a carotid electromagnetic flowmeter, decreas

12. GABAergic and glutamatergic effects on behaviour in fetal sheep.
1. Studies were carried out in unanaesthetized fetal sheep at 125-135 days gestation to investigate neurotransmitters involved in behavioural state. 2. Catheters and electrodes were chronically placed to record tracheal and arterial pressure, electrocortical activity (ECoG), nuchal muscle activity and to instill drugs into the cerebrospinal fluid (CSF) of th
