phytoporphyrin

06/01/2010 - "The sera of facial eczema-affected cattle and sheep had concentrations of phytoporphyrin ranging from 0.4 to 1.8 and 0.9 to 2.8 microM, respectively. "
06/01/2003 - "To establish a method for measuring phylloerythrin in plasma or serum and skin from lambs photosensitised after ingestion of the plant, Narthecium ossifragum, which induces an hepatogenous photosensitisation similar to the disease known as facial eczema in sheep. "
03/01/1983 - "While an obliterative cholangitis is responsible for the retention of phylloerythrin in facial eczema, the occlusion of bile ducts with crystalloid material (microliths) appear to perform a similar function in geeldikkop. "
06/01/2003 - "To study the increase in phylloerythrin concentration in plasma and the disposition of phylloerythrin in skin and other tissues of sheep in which the hepatogenous photosensitisation,facial eczema, had been experimentally induced by dosing with the mycotoxin, sporidesmin. "
06/01/2003 - "Spectrofluorometric analysis of phylloerythrin (phytoporphyrin) in plasma and tissues from sheep suffering from facial eczema."

01/01/1992 - "Hence it is possible that lesions in hepatocytes contribute to retention of phylloerythrin and so to photosensitization."
11/01/1976 - "Presence of phylloerythrin in the blood is a prerequisite for the photosensitization. "
12/01/2006 - "Hepatogenous photosensitization occurs in livestock following damage to the liver or biliary apparatus that results in impaired excretion of phytoporphyrin (phylloerythrin), a photosensitizer. "

01/01/1988 - "Future research is required in order to identify the lantana toxin, antidotes against lantana poisoning, cell-bilirubin/phylloerythrin interactions, cheaper weedicides, allelochemics and finally to obtain more effective phytophagous insects for fighting the lantana menace."

06/01/2018 - "The plant's secondary metabolites/drugs may cause toxicity when bacteria, viral agents, fungi (Pithomyces chartarum), or neoplasia injures the liver and prevents the phylloerythrin excretion. "

09/05/2013 - "A higher degree of initial hemolysis and a higher concentration of the exogenous photosensitizer phytoporphyrin (PP) were detected in alveld sera compared to the controls. "
