RESUMO

Potassium phosphonate is a fungicide widely used to control Phytophthora fungi species in many crops all over the world. In this paper, an attempt has been made to study the interaction of potassium phosphonate with soil under varying pH and calcium level. Several reports available in literature indicate that the phosphonate in organic form adsorb strongly on almost all mineral surfaces and natural materials like soil and sediments. The present study conducted on laterite soil of Kerala using 2 mm sieved sample indicated that phosphonate obeys Freundlich adsorption isotherm. Though at lower concentrations, Langmuir model equally fits well, deviation was observed at higher concentrations. pH and calcium content of the soil had striking influence on the interaction of the chemical with the soil. The calcium source also appeared to influence the adsorption phenomenon. Since potassium phosphonate is extensively used to control Phytophthora fungi species in black pepper (Piper nigrum) plantations in India and liming is a standard practice followed as soil amendment in acid soils to increase the soil pH, this study may help to maintain good soil quality.

RESUMO

Congenital esophageal duplications represent about 15% of digestive tract duplications. We report a 38-year-old man who presented with longstanding heartburn and recent dysphagia. Endoscopy showed communicating tubular duplication of lower esophagus with ulceroproliferative growth at the gastric cardia extending into the lower esophagus. Histology of radical esophagogastrectomy specimen showed poorly differentiated adenocarcinoma of gastric cardia without evidence of Barrett's esophagus.

RESUMO

OBJECTIVE: To compare the efficacy and safety of nimesulide and paracetamol as antipyretic agents. DESIGN: Double blind, randomized clinical trial. METHODS: Hospitalized patients having fever due to a variety of infections were given either drug in a randomized manner. (Nimesulide group = 49, Paracetamol group = 50). Serial axillary temperature was recorded after drug administration and side effects monitored. RESULTS: The mean temperature after one hour of drug administration was significantly lower in nimesulide group (p < 0.05). Significantly fewer doses of nimesulide were required to bring down the temperature on the first day (p < 0.001). The mean maximum temperature recorded on second and third day was significantly lower in the nimesulide group (p < 0.05). Adverse reactions were seen in the form of epigastric pain and vomiting in one patient in Nimesulide group and three in paracetamol group. CONCLUSION: Nimesulide is more effective than paracetamol as an antipyretic agent and is safe for use in infants and children.
