in the present study ethanol and water extracts of 15 seaweeds, dictyota dichotoma var. velutricata, dictyota indica, iyengaria stellata, padina pavonia, sargassum swartzii, sargassum variegatum, stoechospermum marginatum, stokeyia indica, jolyna laminarioides, caulerpa taxifolia, halimeda tuna, ulva fasciata, ulva lactuca, solieria robusta, and melanothamnus afaqhusainii, were evaluated for th...

introduction: the purpose of this study was to determine alkaline phosphatase (alp) activity of ovary after ovarian induction using pregnant mare serum gonadotropin (pmsg) and human chorionic gonadotropin (hcg) during implantation periods. material and methods: a total of 240 female nmri mice aged 6-10 weeks were selected and divided into control and hyperstimulated. these mice were rendered no...

background: in the present investigation radiation and cadmium induced biochemical changes in the kidney of swiss albino mice have been studied. materials and methods: for this purpose, adult male swiss albino mice (6-8 weeks old) were divided into four groups. group i (sham-irradiated), group ii (treated with cdcl2 solution 20 ppm), group iii (irradiated with 1.25, 2.5 and 5.0 gy gamma rays), ...

objective(s): bone marrow mesenchymal stem cells (mscs) play an important role in bone health. cadmium causes osteoporosis, but the exact mechanisms of its effect on mscs are not known. materials and methods: rats were treated with cadmium chloride (40 mg/l) in drinking water for six weeks, and then the biochemical and morphological studies on mscs were carried out as a cellular backup for oste...

background: pectinases are pectin degrading class of enzymes including polygalacturonase (pg), polymethyl galacturonase (pmg), pectate lyase (pel), and pectin esterase (pe) that are commonly used in processes involving the degradation of plant materials, such as speeding up the extraction of fruit juices.objectives: a highly methylated pectin degrading bacterium from soil covered with fruit was...

Background: Cholesterol oxidase (CHO) has various clinical and industrial applications. Recently, microbial CHO have received a great attention for their wide usage in medicine. Here, taxonomic characterizations of isolated strain from soil, optimization of the conditions for CHO production and biochemical characterizations of produced CHO enzyme were described. Finally, CHO gene was cloned int...

We describe a method for determining lipase (triacylglycerol acyl-hydrolase, EC 3.1.1.3) activity in serum. Emulsified olive oil in tris(hydroxymethyl)aminomethane buffer is used as substrate. The course of the enzymatic reaction is followed by measuring the decrease in fluorescence with time of a fluorescent indicator, 4-methylumbelliferone, added to the substrate, caused by the change in the ...

I . Lysozyme activity was estimated in plasma and leucocytes of twelve children suffering from kwashiorkor, thirteen children with ocular signs of vitamin A deficiency and ten apparently normal children acting as controls. 2. The results showed that the activity of lysozyme in leucocytes was significantly reduced in children with kwashiorkor and in vitamin A-deficient children. Following therap...
