The present study was focused on evaluating the potential of Emblica officinalis against cariogenic properties of Streptococcus mutans, a causative microorganism for caries. The effect of crude extract and ethanolic fraction from Emblica officinalis fruit was analysed against S. mutans. The sub-MIC concentrations of crude and ethanolic fraction of E. officinalis were evaluated for its cariogeni...

It is shown that ultrafiltration could be the first step in urine formation in Sepia officinalis and Octopus vulgaris. The organization of the podocytes indicates that ultrafiltration can occur through these cells. They have a thick basal lamina in contact with the peripheral blood lacunae, and the cell apices lie in infoldings of the lumen of the appendage. Comparison between the colloid-osmot...

Body patterning behavior in unshelled cephalopod molluscs such as squid, octopuses, and cuttlefish is the ability of these animals to create complex patterns on their skin. This behavior is generated primarily by chromatophores, pigment-containing organs that are directly innervated by central motoneurons. The present study focuses on innervation patterns and location of chromatophore motoneuro...

BACKGROUND Alzheimer's disease is characterized by a slow, progressive decline in cognitive function and behaviour. Acetylcholine esterase inhibitors are the only agents approved by the Food and Drug Administration for the treatment of Alzheimer's disease. All other agents prescribed for the treatment of Alzheimer's disease are used on an off-label basis. Current research into new drugs is focu...

INTRODUCTION In cirrhosis some toxic substances accumulate in brain and modify the expression of several neuronal receptors. Thus, the use of medicinal plants such as Rosmarinus officinalis L. has been proposed in several pathologies due to its hepatoprotective, antioxidant and neuroprotective activity. In this study we evaluated the expression of the subunits NR1, NR2A and NR2B of the glutamat...

Thin-layer chromatographic method, with postchromatographic derivatization, was applied for the purposes of the quality control of pharmaceutical preparations, containing S. officinalis L. extract. Six finished products underwent the analysis: capsules, tablets, two ointments, tincture and finished product being a mixture of ethanolic S. officinalis and Thymi vulgaris extracts. Chromatographic ...

In the present study, coarse powder of Scindapsus officinalis (Roxb.) Schott. fruit was extracted successively using hexane, chloroform, ethyl acetate and 50% ethanol. The ethyl acetate and 50% ethanolic extracts were investigated for its antioxidant activity by using nitric oxide and DPPH radical scavenging methods. The IC value was also calculated. Ascorbic acid was used as standard. Both the...

OBJECTIVE We aimed to assess the influence of Melissa officinalis (lemon balm), a well-known herbal drug with numerous applications in traditional and modern medicine, on cardiac conduction and susceptibility to lethal ventricular arrhythmia. MATERIALS AND METHODS Forty-two male Wistar rats were divided into a control group (CTL), an M. officinalis group that received the aqueous extract of M...

The common cuttlefish (Sepia officinalis) communicates and camouflages itself by changing its skin colour and texture. Hanlon and Messenger (1988 Phil. Trans. R. Soc. Lond. B 320, 437-487) classified these visual displays, recognizing 13 distinct body patterns. Although this conclusion is based on extensive observations, a quantitative method for analysing complex patterning has obvious advanta...
