chemometric profile antimicrobial activities of leaf extract of calotropis Procera and calotropis gigantea
Natural Product Research, 2017Co-Authors: Pratap Keshari Pattnaik, Hiranyamayee Chhatoi, Sajad Shahbazi, Goutam Ghosh, Ananya KuanarAbstract:AbstractCalotropis Procera and Calotropis gigantea are medicinal plant having therapeutic value. The leaf extracts of C. Procera have been investigated, its pharmacological actions in detail and leaf extracts of C. gigantea were not studied till date. The objective of present work was to find the bioactive constituents present in the ethanolic leaf extract of C. Procera and C. gigantea to evaluate their antibacterial and anifungal activities. The major phytochemical groups in C. Procera ethanolic leaf extracts were fatty acid ethyl ester (21.36%), palmitic acid ester (10.24%), linoleic acid (7.43%) and amino acid (8.10%) respectively, whereas ethanolic leaf extracts of C. gigantea contain palmitic acid (46.01%), diterpene (26.53%), triterpene (17.39%), linoleic acid (5.13%) as the major phytochemical groups. Ethanol extract of C. Procera leaves showed the highest inhibition (11 mm) against Escherichia coli, while ethanolic extract of C. gigantea leaves inhibited Klebsiella (20 mm). These findings will use...

clinical and pathological effects of calotropis Procera exposure in sheep and rats
Toxicon, 2011Co-Authors: Joseney Maia De Lima, Francisco J C Freitas, Raimundo Neilson L Amorim, Antonio Carlos Lopes Câmara, Jael Soares Batista, Benito SotoblancoAbstract:This study aimed to describe the toxic effects resulting from the administration of Calotropis Procera (Aiton) W. T. Aiton latex to rats and C. Procera leaves to sheep. We studied male sheep that received C. Procera leaves by gavage. Twenty male rats were separated into 5 groups and were subjected to an intra-peritoneal injection of fresh C. Procera latex (without carrier solvent) at 1.0, 0.6, 0.3 or 0.1 ml of latex/kg of body weight, and control animals were injected with 0.9% NaCl. All rats were treated with the highest dose, but none of the rats from the other groups, died. The histological lesions were restricted to rats dosed with 1.0 ml of latex/kg body weight and included multi-focal coagulation necrosis of cardiac fibers and vacuolized hepatocytes. Subsequently, three groups of two sheep were treated with (1) a single dose of 30 g/kg, (2) a single dose of 60 g/kg or (3) 60 g/kg per day for 10 consecutive days. Exposure to the C. Procera leaves was responsible for tachycardia and transitory cardiac arrhythmias in sheep from all groups. Gross pathological analysis of sheep dosed with 60 g/kg per day for 10 days revealed mild ascites, exudates on the trachea, pulmonary edema, mild hemorrhage in the liver, hydropericardium, flaccid heart, ulcers on the abomasum and kidneys presenting pale juxtamedullary cortex. The histological findings of the rat and sheep studies were similar and included multi-focal coagulation necrosis of cardiac fibers and vacuolized hepatocytes. In conclusion, our findings indicate that C. Procera is a cardiotoxic and hepatotoxic plant.

Use of zinc phosphate cement as a luting agent for Denzir™ copings: an in vitro study
BMC Oral Health, 2003Co-Authors: Karl-johan M. Söderholm, Eduardo Mondragon, Ileana GarceaAbstract:Background The clinical success rate with zinc phosphate cemented Procera crowns is high. The objective with this study was to determine whether CADCAM processed and zinc phosphate cemented Denzir copings would perform as well as zinc phosphate cemented Procera copings when tested in vitro in tension. Methods Twelve Procera copings and twenty-four Denzir copings were made. After the copings had been made, twelve of the Denzir copings were sandblasted on their internal surfaces. All copings were then cemented with zinc phosphate cement to carbon steel dies and transferred to water or artificial saliva. Two weeks after cementation, half of the samples were tested. The remaining samples were tested after one year in the storage medium. All tests were done in tension and evaluated with an ANOVA. Results Sandblasted and un-sandblasted Denzir copings performed as well as Procera copings. Storage in water or artificial saliva up to one year did not decrease the force needed to dislodge any of the coping groups. Three copings fractured during testing and one coping developed a crack during testing. The three complete fractures occurred in Procera copings, while the partly cracked coping was a Denzir coping. Conclusion No significant differences existed between the different material groups, and the retentive force increased rather than decreased with time. Fewer fractures occurred in Denzir copings, explained by the higher fracture toughness of the Denzir material. Based on good clinical results with zinc phosphate cemented Procera crowns, we foresee that zinc phosphate cement luted Denzir copings are likely to perform well clinically.
