Bioresidual efficacy and phytotoxicity of certain systemic nematicides against root-knot nematode infesting tomato plants

The bioresidual efficacy and phytotoxic effects of four systemic nematicides: akldicarb, carbofluran, oxamyl and fenamiphos against root-knot nematodes infesting tomao plants were evaluated in laboratory and greenhouses. The obtained results indicated the important role of nematicide type on the studied nematodes and tomato plants. Fenamiphos proved more effectiveness than the other nematicides tested against the root-knot nematode larvae, followed by akldicarb. The highest inhibition of gall formation was obtained by fenamiphos, while oxamyl was the lowest inhibitor. General, for all tested nematicides at the evaluated concentrations, the best inhibition was achieved when the nematicide was applied at the time of inoculation. The nematicides tested except fenamiphos showed clear phytotoxic symptoms on treated tomato plants characterized by significantly reduction in the dry weight of plant roots and shoots. Among the tested nematicides only carbofuran decreased significantly the height of treated tomato plants

Esquema corto de Praziquantel para el tratamiento de la neurocisticercosis parenquimatosa / Short regimen of Praziquantel for the treatment of parenclymatose neurocysticercosis

Objetivo. La terapia para la neurocisticercosis parenquimatosa con praziquantel (PZQ) de 15 días ha mostrado ser efectiva. Las concentraciones en plasma y líquido cefalorraquídeo (LCR) del PZQ son más elevadas después de dos horas de su administración. Nosostros pensamos que el mantenimiento de concentraciones elevadas de PZQ por seis horas pudieran ser una terapia cisticida adecuada para estos pacientes. Métodos. Tratamos 30 pacientes con neurocisticercosis parenquimatosa con tres dosis orales de 25 mg por kg de peso de PZQ con intervalos de dos horas. Ellos recibieron dexametasona 10 mg intramuscular por tres días consecutivos a la administración del PZQ. Resultados. En 21 pacientes desaparecieron los quistes, en siete hubo una desaparición de 30 a 60 por ciento y dos pacientes permanecieron sin cambios. Del número total de quistes, hubo una tasa de desaparición de 70.7 por ciento. Dos pacientes presentaron crisis convulsivas, seis cefalea y otros más náusea. Ningún paciente cursó con convulsiones durante el tratamiento con antiepilépticos. Conclusión. El costo y el tiempo de administración del PZQ se reducen significativamente y la inflamación que sigue a la destrucción del parásito es tratada secuencialmente

Metabolic acidosis induced by cetrimide-chlorhexidine solution in hydatid cyst surgery.

A patient with a large hydatid cyst of the left lobe of the liver developed metabolic acidosis following rather liberal use of cetrimide-chlorhexidine solution as a scolicidal agent. The progress and management of this complication are described in the patient is being reported.

Treatment of taeniasis with Puag-Haad: a crude extract of Artocarpus lakoocha wood.
