ICD-85 (venom derived peptides) has anti-proliferative effect and anti-angiogenesis activity on cancer cells. This study was performed to test the effect of ICD-85, on Human breast adenocarcinoma (MCF-7) and normal Human Dermal Fibroblasts (HDF) cell lines. In this experimental study, Mitochondrial activity, Neutral red uptake, Lactate dehydrogenase (cell necrosis), and cell morphology we...

We report observations from time-lapse films of the development of Dictyostelium discoideum (Dd) stained with the vital dye neutral red. We have used this dye to enable us to track individual cells, as they move through multicellular tissues in later Dd stages. Our observations lead us to new conclusions about the control of cell movement and cell contact during Dd development, including the te...

We now add to the agencies by which cells take up lithium the process of cotransport with neutral amino acids via System A. In the Ehrlich cell various natural and synthetic amino acids, depending on their structure, can cause substantial accelerations of Li+ uptake over a considerable range of levels of Na+, Li+ and H+. Half the maximal augmentation of uptake, namely 1.2 mequiv. Li/kg cell wat...

Dictyopteris membranacea, a species of Mediterranean brown algae, is believed to have potential pharmacological and nutritional applications. However, such potentials only make sense when devoid of any adverse health consequences. The present study should be seen in this context. It aimed at evaluating the genotoxicity and cytoxicity of its organic extract (F0) and semi purified fractions (F4, ...

Neutral red is a dye the azine structure which has been used as an acido-base indicator and a dye in histochemistry. In 1960 Goldhaber introduced Neutral red into the medium of resorbing bone cultures to localize the osteoclast in the living cultures. Using time-lapse microcinematography in order to follow the osteoclasts, he reported excellent contrast could be obtained with Neutral red due to...

The common marine mussel A4yt~lus edulls was used in laboratory-controlled experiments to investigate the effects of exposure to cadmium on immune capability Haemolymph was extracted from mussels exposed for 7 d to 40 and 400 pg 1 ' of cadmium, and assays were carned out to investlgate the potent~al for immune response The assays included total and differential haemocyte counts, the release of ...

It has been reported that amiodarone induces disorders of alveolar macrophages and pulmonary fibrosis, but the mechanism is not well-understood. This study was performed to elucidate the toxic mechanism from the standpoint of cellular function. Using alveolar macrophages obtained from a male Slc:ICR mouse, several injuries caused by amiodarone were compared to those caused by amantadine and mia...
