Heavy metal contamination may have adverse effects on wetland biota, particularly on amphibians. Severe immunotoxic effects elicited in Euphlyctis hexadactylus (Indian green frog) because of metal exposure (Cd, Cr, Cu, Pb, and Zn) in the Bellanwila-Attidiya Sanctuary, a polluted urban wetland in Sri Lanka, provided the rationale for the present study. We evaluated the biochemical and histopathological effects of this metal contamination with a reference E. hexadactylus population and a laboratory exposure group that was subjected to 28 d of exposure to a mixture of Cd, Cr, Cu, Pb, and Zn (5 ppm in each mixture)...

BACKGROUND: The leaf concentrate of Carica papaya is a traditionally acclaimed immunomodulatory remedy against numerous diseases; nonetheless comprehensive scientific validation of this claim is limited. The present study thus investigated the immunomodulatory potential of Carica papaya mature leaf concentrate (MLCC) of the Sri Lankan wild type cultivar using nonfunctional and functional immunological assays. METHODS: Wistar rats (N = 6/ group) were orally gavaged with 3 doses (0...

BACKGROUND: Anabolic steroids have been reported to improve wound healing. OBJECTIVE: To determine whether oxandrolone increases the percentage of target pressure ulcers (TPUs) that heal compared with placebo and whether healed ulcers remain closed 8 weeks after treatment. DESIGN: Parallel-group, placebo-controlled, randomized trial conducted from 1 August 2005 to 30 November 2008. Patients, clinical care providers, study personnel, and statisticians were blinded to treatment assignment...

A 26-yr-old man with a C4 American Spinal Injury Association impairment scale B spinal cord injury was admitted due to a left calf pressure ulcer. The patient's initial laboratory results and physical examination findings were unremarkable, except for a stage IV pressure ulcer. On day 7, the patient developed fever and leukocytosis. A complete culture workup performed did not yield abnormalities. A computed tomography scan of the abdomen and pelvis revealed retrocecal appendicitis with a retrocecal abscess containing an appendicolith...

The objective of this article was to determine the current practice on amikacin dosing and monitoring in spinal cord injury patients from spinal cord physicians and experts. Physicians from spinal units and clinical pharmacologists were asked to provide protocol for dosing and monitoring of amikacin therapy in spinal cord injury patients. In a spinal unit in Poland, amikacin is administered usually 0.5 g twice daily. A once-daily regimen of amikacin is never used and amikacin concentrations are not determined...

OBJECTIVE: To investigate the usefulness of performing routine urine cultures in veterans with spinal cord injury (SCI) who come for annual evaluation. RESEARCH DESIGN/PARTICIPANTS: This retrospective study was performed on asymptomatic patients who came for outpatient annual evaluation. The records of 89 healthy male veterans with SCI between the ages of 22 and 82 years (mean age = 50.6) were reviewed from March through October 2000. METHODS: The following information was collected: patient's name, social security numbers, age, year of injury, level of injury, American Spinal Injury Association (ASIA) classification, urinalysis including white blood cell (WBC) count and presence or absence of nitrite, urine culture results (> or <100,000 colony-forming units of uropathogens per milliliter), blood WBC count, and mode of bladder management...
