A laser photolysis technique has been developed to assess the quantitative significance of the delay time of hemoglobin S gelation to the pathophysiology of sickle cell disease. Changes in the saturation of hemoglobin S with carbon monoxide produced by varying the intensity of a photolytic laser beam were used to simulate changes in the saturation of oxyhemoglobin S produced by variations in ox...

Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at hi...

Carboxyhemoglobin (COHb%) and gamma-glutamyl-transferase (GGT) are indicators of tobacco and alcohol consumption; similarly, body weight broadly reflects dietary habits. Relationships between COHb%, GGT, relative body weight, heart rate and blood pressure were studied in 242 48-year-old men attending a general health screening program in Malmö, Sweden. All were without treatment for high blood ...

Methodology: Cardiovascular system examination and Electrocardiography (ECG) were performed for fifty CO intoxicated patients admitted to Poison Control Center, Ain Shams university Hospital for whom some oxidative stress indices have been investigated through the assessment of plasma level of malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide (NO). Both cardiac enzymes; troponi...

BACKGROUND Firefighters are frequently exposed to significant concentrations of hazardous materials including heavy metals, aldehydes, hydrogen chloride, dichlorofluoromethane and some particulates. Many of these materials have been implicated in the triggering of several diseases. The aim of the present study is to investigate the effect of fire smoke exposure on serum heavy metals and possibl...

Conventional pulse oximetry uses two wavelengths of light (red and infrared) transmitted through a finger and a photodetector to analyze arterial hemoglobin oxygen saturation and pulse rate. Recent advances in pulse oximetry include: extended analysis of the photo plethysmographic waveform; use of multiple wavelengths of light to quantify methemoglobin, carboxyhemoglobin and total hemoglobin co...
