Crocodile blood extracts; serum, plasma, hemoglobin, and crude leukocyte extract were prepared from whole blood of crocodiles (Crocodylus siamensis) by differential sedimentation. In this study, crocodile blood extracts possessed considerable cytotoxic activity. It was evident that, the serum, plasma, hemoglobin, and crude leukocyte extract have not significant cytotoxic potentials by the yello...

objective: the present study was an attempt to study total phenolic content and antioxidant property of the crude ethanolic extract of the roots of azadirachta indica (a. indica). materials and methods: to evaluate the antioxidant properties of the crude extract, some complementary test systems, namely dpph free radical scavenging assay, reducing power assay, and ferrous ion chelating ability a...

To study the anti-diabetic effects of the crude leaves extract and fractions of Thymus schimperi Ronniger in normal and steptozotocin induced diabetic mice. The crude extract and the fractions were screened for antidiabetic activities in streptozotocin induced diabetic mice. A normoglycemic mice model and oral glucose tolerance test were also undertaken to assess the hypoglycemic and antihyperg...

results in vitro analysis showed that the greater the concentration of the extract, the greater the cytotoxicity. conclusions the crude extract of p. australis might be cytotoxic at high concentrations as evaluated against the cell line. materials and methods the mtt cytotoxicity assay was performed on a 3t3 mouse fibroblast cell line to measure the in vitro cytotoxic activity of the crude form...

Von Euler and Vestin (1) demonstrated the synthesis of triphosphopyridine nucleotide (TPN) when diphosphopyridine nucleotide (DPN) was incubated with adenosine triphosphate (ATP) in the presence of crude yeast maceration juice. In subsequent reports (2) from the Stockholm laboratory, several mechanisms for this reaction were considered but none was established. With crude pigeon liver fractions...

The crude extract of Ampelopsis cantoniensis induced apoptosis in human promyelocytic leukemia HL-60 cells and this induction was investigated by flow cytometric analysis, DNA gel electrophoresis and poly (ADP-ribose) fluorescence staining. The results demonstrated that this extract induced dose-dependent cytotoxicity and apoptosis. The level of active caspase-3 was increased after treatment wi...

The xylanolytic enzyme complex hydrolyzes xylan, and these enzymes have various industrial applications. goal of this work was to characterize the endoxylanases produced by thermophilic fungus Rasamsonia emersonii in solid-state cultivation. Tests were carried out evaluate effects pH, temperature, glycerol phenolic compounds on activity. Thermal denaturation one isolated evaluated. crude extrac...

Tilapia have high resistance to various diseases, tolerance low and temperatures, efficiency in feed fast growth, recently growing saline water with salinity up 20 ppt. The addition of Sargassum extract into the is an alternative maintain quality digestibility fish body. sp, has a fairly complete nutritional content, it can certainly growth effect when added feed, according previous research. c...
