1. 36. Pathophysiology of blood-brain barrier, brain edema and cell injury following hyperthermia : New role of heat shock protein, nitric oxide and carbon monoxide : an experimental study in rat using light and electron microscopy

   Författare :Hari Shanker Sharma; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; blood-brain barrier; heat stress; hyperthermia; brain edema; serotonin; nitric oxide; carbon monoxide; heat shock protein; glial fibrillary acidic protein; myelin basic protein; opioids; histamine; catecholamines; naloxone; indomethacin; p-CPA; electron microscopy; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

   Sammanfattning : This thesis deals with the molecular mechanisms of hyperthermia induced brain damage in rats. The results clearly establish that hyperthermia caused by 4 h heat stress at 38° C is associated with a breakdown of the blood-brain barrier (BBB) permeability which seems to be instrumental in causing brain edema and cell injury.

3. 37. Endothelin and nitric oxide in the fetoplacental circulation

   Författare :Anna Sand; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Fetoplacental circulation; placental arteries; endothelin-1; nitric oxide; potassium channels; M-CSF; endothelin receptors; BKCa; ETA; ETB;

   Sammanfattning : Background: Normal fetal growth and development depend on a satisfactory uteroplacental and fetoplacental blood flow. This will ensure an adequate gaseous exchange and nutritional supply to the fetus. LÄS MER

4. 38. On the role of nitric oxide in uterine secretion

   Författare :Birgitta Mörlin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Autonomic nerves; endometrial and cervical secretion; nitric oxide; guineapig.;

   Sammanfattning : Background: Uterine secretion is important in many different aspects of reproduction e.g. sperm transport and survival, fertilization, nourishment of the ovum and implantation. A cholinergic autonomic nervous secretory innervation has been established and modulation of the secretion by prostaglandins and NSAID drugs has been postulated. LÄS MER

5. 39. Nitric oxide, formation and effects in the urogenital tract

   Författare :Ingrid Ehren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :urinary tract; male reproductive tract; nitric oxide; nitric oxide synthase; NADPH-diaphorase; smooth muscle; secretion; inflammation; sex hormones.STOCKHOLM 1996 ISB;

   Sammanfattning : The aim of the thesis was to study the formation and effects of nitric oxide (NO) in the human urinary tract and in the male reproductive organs. In the human upper and lower urinary tract NO synthase activity was studied via the formation of radiolabeled L-citrulline from L-arginine. LÄS MER

7. 40. Studies on production and function of pulmonary nitric oxide

   Författare :Christofer Adding; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adrenaline; adrenoceptors; beta-adrenoceptors; calcium; carbon dioxide; catecholamines; chemiluminescence; exhaled; gadolinium chloride; high frequency oscillatory ventilation; nitric oxide; pulmonary; pulmonary circulation; stretch; sympathoadrenal; veratrine;

   Sammanfattning : Nitric oxide is involved in pulmonary vascular and bronchial regulation and appears to be of paramount importance in the adaptation of the pulmonary circulation at birth. Nitric oxide is present in exhaled gas. LÄS MER
