STUDIES ON THE HISTOPATHOLOGY AND OXIDATIVE STRESS OF SOME ORGANS OF MICE INFECTED WITH TOXASCARIS LEONINA (LISTOW, 1902) (NEMATODA)

The effect of seasonal variations on the fatty acid composition of three Nile fish species; Tilapia nilotica (LINNAEUS, 1757), Clarias lazera (CUVIER and VALENCIENES, 1840) and Synddontis scall (BLOCH-SCHNEIDER, 1801) was studied. The determination of fatty acids was carried out applying gas liquid chromatogra phic analysis. The data revealed that lipids of the three studied fish species were found to contain 18 fatty acids with carbon chains ranging from C to Cja, most which were unsaturated fatty acids. Both saturated and unsaturated fatty acids varied markedly due to seasonality, since the percentage of saturation of fish lipid varies according to season. The data revealed that the relative content of unsaturated fatty acids increased markedly in spring in the three studied fish species.

Effect of seasonal variations on phospholipid components in three Nile fish species.

This investigation was carried out to study the effect of seasonal variations on the essential amino acids in trunk skeletal muscles (myotomal musculature) under the dorsal fin of three Nile fish species; namely: Tilapia nilotica (LINNAEUS, 1757), Clarias lazerat (CUVIER and VALENCINNES, 1840) and Synodontis schall (BLOCH SCHNEIDER, 1801). Qualitative and quantitative essential amino acids determination was carried out using thin layer chromatographic analysis, while the tryptophan content was evaluated applying the chemical method. Data obtained revealed that all essential amino acids were present in the three studied fish species in variable levels, depending on the species and season. Moreover, the major amino acids concentration of the three studied fish species was in the following descending order: threoni ne, methionine, valine, arginine and lysine. The relative concentration of each amino acid in the total amino acids content remains constant in spite of the changes in that total amount due to different biological and enviromental conditions.

Thirty-two mature male rabbits were used in this study. They were divided into two groups: the control group (n= 8) and the experimental (n= 24) group; the experimental group was injected intraperitoneally with alloxan (180mg/ml/kg body weight). After 3 weeks, this group (diabetic rabbits) was subdivided into three subgroups of eight rabbits each. The first one was left as the untreated diabetic subgroup; rabbits in the second and third subgroups were treated daily for 7 days with ALA and NAC (100 mg/ml/kg body weight), respectively. At the end of the experiment, blood and kidney sections were processed for biochemical and histological studies.

Oxidant/antioxidant status of erythrocytes from patients falciparum malaria in Yemen and its relation with the intensity of parasitemia

Burden of Parasitaemia, Falciparum Malaria and Serum Glucose, Urea and Creatinine among Patients in Abbs (Tehama-Hajjah), Yemen

This study was conducted to evaluate the integrative antioxidant potency of fenugreek seeds suspension powder (FSPS), vitamin E (Vit E), and sodium selenite (Se) against mercuric chloride toxicity (MC) induced oxidative stress in both erythrocytic lysate (EL) and testicular tissue (TT) in Albino male rats. MC was administered orally in drinking water (DW: (50 mg/L= 1/15 of LD50). FSPS (100 g/L soaked for day), Se (2 mg/L) were administered in DW and vit E 150 (mg/100 g diet) mixed in the diet as. The rats were divided into six groups, ten rats each. The first group was control with normal diet and tape water. The second group, consider as positive control, DW containing MC. The third received Vit E (with diet) in addition to MC, the fourth group received MC + Se. The fifth one received MC and FSPS. Finally, the sixth group combination group (COMB group) received DW containing MC, Se in addition to Vit E …

Effect of seasonal variation on weight composition and gross composition of three Nile fish species.

This study was designed to investigate the effect of Neem seed oil on the oxidative stress in gills and erythrocytes (EC), after 1, 2 and 3 weeks (W) and to evaluate the antioxidant effect of lupine seed supplementation (LS) in the Nile tilapia   Oreochromis niloticus. Two doses of Neem oil; 1/20 LC50:56 (NO1) and 1/10 LC50:112 PPM (NO2) and three periods of one, two and three weeks were used. Oxidative stress parameter, total peroxide (TP) and antioxidant enzyme activities, catalase (CAT) and superoxide dismutase (SOD) as well as glycemia were measured. NO2 markedly decreased CAT and SOD activities in gills at most periods (52 - 99% and 16 – 52 %, respectively) and in EC (22 - 62 and 48 – 63 %, respectively) in most periods, but NO1 had less effect. In turn, both doses significantly enhanced TP levels in gills and EC. Moreover, hyperglycemia was detected three weeks after control (NO) exposure. LS significantly curtailed or abolished the adverse effect of NO exposure on oxidative and antioxidant parameters in gills and EC. This may be attributed to the hypoglycemic effect of LS as well as its antioxidant efficiency. In conclusion, NO exerts oxidative damage in the fish and LS has an antioxidant potency.
