BACKGROUND Persea americana seeds are widely used in traditional Mexican medicine to treat rheumatism, asthma, infectious processes as well as diarrhea and dysentery caused by intestinal parasites. METHODS The chloroformic and ethanolic extracts of P. americana seeds were prepared by maceration and their amoebicidal, giardicidal and trichomonicidal activity was evaluated. These extracts were ...

The present study reports the reversing effects of extracts from P. americana on multidrug resistance of BEL-7402/5-FU cells, as well as a preliminary investigation on their mechanism of action. A methylthiazolyl tetrazolium (MTT) method was applied to determine the multidrug resistance of BEL-7402/5-FU, while an intracellular drug accumulation assay was used to evaluate the effects of a column...

Insulin-stimulative and anti-oxidative effects of Persea americana fruit extract were evaluated using streptozotocin (STZ). Ethanol extract of P. americana in the concentration of 300 mg/kg body weight/rat /day was orally administered to rats introduced into STZ-induced hyperglycaemic state for a period of 30 days. After the treatment with avocado fruit extract, the elevated levels of blood glu...

In this Article, the legend of Figure 5 and Figure 6 are incorrect: In Figure 5: " Phylogenetic analysis of RPSA in insect species. Neighbor-joining method was used to construct the phylogenetic tree. Bootstrap values with 1000 trials are indicated on branches. " should read: " Quantification of the expression level of fruitless gene in ovary and testis of P. americana with real-time PCR. The e...

DNA barcoding promises to be a useful tool to identify pest species assuming adequate representation of genetic variants in a reference library. Here we examined mitochondrial DNA barcodes in a global urban pest, the American cockroach (Periplaneta americana). Our sampling effort generated 284 cockroach specimens, most from New York City, plus 15 additional U.S. states and six other countries, ...

BACKGROUND The oral cavity is the store house of different species of microorganisms that are continuously engaged in causing diseases in the mouth. The present study was conducted to evaluate the antibacterial potential of crude extracts of the aerial parts of Phytolacca americana and its natural compounds against two oral pathogens, Porphyromonas gingivalis and Streptococcus mutans, which are...

BACKGROUND Periplaneta americana extract is recognized to have a positive effect on gastrointestinal mucosa. This study aimed to investigate the effects of periplaneta americana extract on immune function, nutrition status and gastrointestinal complications of early enteral nutrition patients with systemic inflammatory response syndrome (SIRS). METHODS Patients with SIRS were randomly divided...

BACKGROUND A great revival of scientific interests in drug discovery has been witnessed in recent years from medicinal plants for health maintenance. The aim of this work was to investigate three Nigerian medicinal plants collected in Nigeria for their in vitro antiplasmodial and antimicrobial activities. MATERIALS AND METHODS Extracts obtained from parts of Persea americana, Jatropha podagri...

conclusions the results showed that p. americana is a possible reservoir and potential vector of some pathogenic agents. results one hundred percent of cockroaches had bacterial infections. culturing of the external parts wash homogenates resulted in the isolation of escherichia coli, proteus, serratia, klebsiella, enterobacter, pseudomonas, staphylococcus aureus, streptococcus, enterococcus, c...
