Massive cyanide poisoning occurred in a 21-year-old man who had ingested 600 mg of potassium cyanide. The clinical course was marked by acute pulmonary edema and lactic acidosis. Because the poison was unidentified until nine hours after ingestion, the patient received only supported treatment which
Isolated rabbit corneas bathed in Krebs-bicarbonate Ringer solution were observed for thickness changes after a 90 minute equilibration period. Control corneas swelled an average of 0.5 micron/hr, and placement of a polymethylmechacrylate (PMMA) contact lens on the epithelial surface caused the
Acute cyanide (CN) toxicity was investigated in the Sprague-Dawley rat. Conscious, loosely restrained rats received sodium CN solution at varying dose rates through a jugular cannula (low CN, 0.077-0.155 mg/kg/min; high CN, 0.157-0.204 mg/kg/min). Blood glucose concentration was significantly
Two deaths occurred after ingestion of cyanide-containing Extra-Strength Excedrin capsules. Cranial CT scans obtained within 3 hr of each patient's collapse showed diffuse cerebral swelling and loss of gray-white differentiation. Most diffuse cerebral insults (hypoxia, ischemia) do not show such
OBJECTIVE
To describe the clinical course, ultrasonographic and confocal microscopic findings in a patient who developed a large Descemet membrane (DM) detachment that resolved spontaneously after ocular sodium cyanide injury.
METHODS
Case report.
RESULTS
The patient presented with severe corneal
Pyridoxal 5'-phosphate (PLP), the active form of vitamin B6, readily forms complexes with a wide variety of potentially toxic substances, including cyanide (KCN), spermine (SPM), gentamicin (GM), and dopamine (DOP). The role of PLP as an antidote for these toxicants in vivo was studied. Rats were
This study examined the effects of lung collapse, a condition that causes relative hypoxia in lung tissues, on superoxide dismutase (SOD), cytochrome oxidase (cyt ox), and pyruvate kinase (py ki) activities in rabbits. Cyanide-insensitive respiration measurements were done in collapsed and
The U.S. Air Force utilizes specialized Critical Care Air Transport Teams (CCATT) for transporting "stabilized" patients. Given the drawdown of military forces from various areas of operation, recent CCATT operations have increasingly involved the evacuation of unstable and The poisonous bite by Hippasa partita, a funnel web spider from the Indian subcontinent has been demonstrated to give rise to severe dermo- and myonecrosis. In this work a hemorrhagic metalloprotease, Partitagin was purified from H. partita venom by successive chromatography on Sephadex G-100, DEAE
The main puzzle of the pulmonary circulation is how the alveolar spaces remain dry over a wide range of pulmonary vascular pressures and blood flows. Although normal hydrostatic pressure in pulmonary capillaries is probably always below 10 mmHg, well bellow plasma colloid pressure of 25 mmHg, most
BACKGROUND
Intentional absorption of sodium azide is exceptional but remains extremely life-threatening because death rapidly occurs when significant doses are absorbed, either due to the direct effect of sodium azide or an indirect effect due to nitric oxide, cyanide ions or hydrazoic acid
Burns represent a major cause of accidental death in industrialized countries. Before the recognition of the key role of aggressive volume resuscitation in successful management, early mortality was common secondary to burn shock. Salvage of patients with major burns is optimized only if the
This study was undertaken to determine the site of initial pulmonary injury in smoke inhalation. A hotel fire in Houston, Texas, resulted in the on-site deaths of 10 white people (2 to 62 years of age). All underwent autopsy examinations which included measurement of carbon monoxide (CO) and cyanide
A 55-year-old male Caucasian truck driver was dead at the scene after breathing hydrogen sulfide (H(2)S) produced by an accidental transfer of sodium hydrogen sulfide (NaHS) from a tanker truck to a tank containing 4% sulfuric acid (H(2)SO(4)) and iron(II) sulfate (FeSO(4)). Autopsy of the
