Addition of papaverine to cardioplegia does not reduce myocardial necrosis.

Only registered users can translate articles

In a randomized, double-blind prospective study involving 495 patients, we investigated whether the addition of papaverine, 60 mg, to our existing regimen of cold cardioplegia would reduce myocardial necrosis during elective coronary artery bypass operations. Twenty-one (4.2%) patients sustained

Avoiding Liver Injury with Papaverine and Ascorbic Acid Due to Infrarenal Cross-Clamping: an Experimental Study.

Only registered users can translate articles

UNASSIGNED Ischemia-reperfusion injury after acute ischemia treatment is a serious condition with high mortality and morbidity. Ischemia-reperfusion injury may result in organ failure particularly in kidney, lung, liver, and heart. In our study, we investigated the effects of papaverine and vitamin

Papaverine Has Therapeutic Potential for Sepsis-Induced Neuropathy in Rats, Possibly via the Modulation of HMGB1-RAGE Axis and Its Antioxidant Prosperities

Only registered users can translate articles

Aim: Our aim was to investigate the possible neuroprotective properties of papaverine in sepsis-induced critical illness neuropathy (SCIN) through the evaluation of various inflammatory biochemical markers, including interleukin 6 (IL-6),

Intraarterial infusion of high-concentration papaverine damages cerebral arteries in rats.

Only registered users can translate articles

OBJECTIVE To determine the appropriate concentration of papaverine for therapeutic intraarterial infusion against cerebral vasospasm. METHODS We investigated histopathologic changes in cerebral arteries and brain tissue of normal Wistar rats that had received infusions of papaverine via the carotid

The papaverine test for blood flow potential of the profunda femoris artery.

Only registered users can translate articles

In reconstructive surgery of the arteries, the inflow tract is as important as the distal runoff. Since information about the hemodynamic significance of either cannot be obtained from an arteriogram , accurate assessment of flow within the arterial segment to be reconstructed must be obtained by

Direct toxic effect of iodide in excess on iodine-deficient thyroid glands: epithelial necrosis and inflammation associated with lipofuscin accumulation.

Only registered users can translate articles

Involution of thyroid hyperplasia (induced by a low iodine diet and a goitrogen, propylthiouracil, PTU) was obtained in mice by administering a high or a moderate dose of iodide (HID or MID, respectively). In HID involuting glands, vasoconstriction was observed after 12 hr whereas necrosis and

Interventional Catheterization Combined with Staphylococcin Aureus Injection in 112 Cases of Ischemic Necrosis of Femoral Heads.

Only registered users can translate articles

The objective of this study was to investigate the effectiveness of interventional catheterization with staphylococcin aureus injection on ischemic necrosis of the femoral heads. By percutaneous catheterization of the femoral artery, papaverine, urokinase, compound Danshen, and anisodamine were

Preferential Protection of Cerebral Autoregulation and Reduction of Hippocampal Necrosis With Norepinephrine After Traumatic Brain Injury in Female Piglets.

Only registered users can translate articles

OBJECTIVE Traumatic brain injury contributes to morbidity in children and boys is disproportionately represented. Cerebral autoregulation is impaired after traumatic brain injury, contributing to poor outcome. Cerebral perfusion pressure is often normalized by the use of vasopressors to increase

Inhaled Nitric Oxide Protects Cerebral Autoregulation and Reduces Hippocampal Neuronal Cell Necrosis after Traumatic Brain Injury in Newborn and Juvenile Pigs.

Only registered users can translate articles

Traumatic brain injury (TBI) contributes to morbidity in children, and boys are disproportionately represented. Cerebral blood flow (CBF) is reduced and autoregulation is impaired after TBI, contributing to poor outcome. Cerebral perfusion pressure (CPP) is often normalized by use of vasoactive

Dopamine protects cerebral autoregulation and prevents hippocampal necrosis after traumatic brain injury via block of ERK MAPK in juvenile pigs.

Only registered users can translate articles

Traumatic brain injury (TBI) contributes to morbidity in children, and more boys experience TBI. Cerebral autoregulation is impaired after TBI, contributing to poor outcome. Cerebral Perfusion Pressure (CPP) is often normalized by use of vasoactive agents to increase mean arterial pressure (MAP). In

Comparing the Outcomes of Different Agents to Treat Vasospasm at Microsurgical Anastomosis during the Papaverine Shortage.

Only registered users can translate articles

BACKGROUND Papaverine remains popular for treating intraoperative vasospasm, but the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery but commonly used in other body areas. During this shortage, the authors have used topical lidocaine and nicardipine to

Toxicity assessment of papaverine hydrochloride and papaverine-derived metabolites in primary cultures of rat hepatocytes.

Only registered users can translate articles

The present study was undertaken to assess and compare the toxic effects of papaverine hydrochloride and its metabolites. Primary cell cultures of rat hepatocytes were treated with papaverine (papaver), 3'-O-desmethyl (3'-OH), 4'-O-desmethyl (4'-OH), and 6-O-desmethyl (6-OH) papaverine at 1 x

Inhibitory effects of herbal alkaloids on the tumor necrosis factor-α and nitric oxide production in lipopolysaccharide-stimulated RAW264 macrophages.

Only registered users can translate articles

It is beneficial to treat chronic inflammatory condition in patients through diets that inhibit the production of proinflammatory cytokines and mediators such as tumor necrosis factor-α (TNF-α) and nitric oxide (NO). Since less attention has been paid to alkaloids in the diets than to polyphenols in

Norepinephrine Protects Cerebral Autoregulation and Reduces Hippocampal Necrosis after Traumatic Brain Injury via Blockade of ERK MAPK and IL-6 in Juvenile Pigs.

Only registered users can translate articles

Traumatic brain injury (TBI) contributes to morbidity in children, and boys are disproportionately represented. Cerebral autoregulation is impaired after TBI, contributing to poor outcome. Cerebral perfusion pressure (CPP) is often normalized by use of vasoactive agents to increase mean arterial

Inhaled Nitric Oxide Protects Cerebral Autoregulation and Reduces Hippocampal Necrosis After Traumatic Brain Injury Through Inhibition of ET-1, ERK MAPK and IL-6 Upregulation in Pigs.

Only registered users can translate articles

OBJECTIVE Traumatic brain injury (TBI) is an important contributor to morbidity and mortality. Cerebral autoregulation is impaired after TBI, contributing to poor outcome. Extracellular signal-related kinase (ERK) mitogen activated protein kinase (MAPK) and ET-1 are upregulated and contribute to
