Neem Leaf Extract

The study investigated the effect of Neem Leaf Extract (NLE)—a herbal product on hematological parameters of common carp, Cyprinus carpio. Common carp fry were fed on diets having different levels of NLE [no NLE (D1), 0.25(D2), 0.5(D3), 1.0(D4), 1.5(D5), 2.0(D6) g/kg in basal diet containing rice bran and mustard] for 180 days in outdoor tanks. The results revealed an increase in TEC, TLC and PCV in groups D2-D6 compared to control (P less than 0.05), but increased PCV was observed only in D2, D3 and D4 groups. Further, increasing trend for Hb content was observed from D2-D6 irrespective of NLE levels. The MCV values decreased with increase in levels of NLE in contrast to MCHC, whereas MCH considerably varied among the treatments. Significantly increased total protein and globulin was also observed while albumin to globulin ratio did not show any response in any of the treatments. Collectively, these observations support the hypothesis that the response of hematological parameters to NLE treatment is regulated via both positive and negative feedback mechanisms, with differential modulations based on the NLE levels. The results imply that NLE can boost the immune system via hematological parameters by increasing TEC, TLC, PCV, Hb at certain levels.

The aim of the present study was to assess the effect of a commercial ß-glucan against acute toxic effect of copper sulfate on common carp Cyprinus carpio L. behavioral, hematological parameters and biochemical tests. A total of 250 Fish (150 ± 2 g) were fed a basal control diet or the basal diet plus a ß-glucan (1 g kg-1 diet) for 60 days. LC50 was calculated for 72 h which was 10.83 mg L-1.  At the end of the trial, CuSO4.5H2O was added to all treatments  at a dose  of  5 mgL-1  for  T1  and  T2, 7mg L-1  for  T3  and  T4, 9  mgL-1 for T5  and  T6   for  96h. Fish behavioral changes were recorded during 96h of exposure to different Cu concentrations with and without β-glucan, which showed abnormalities such as increase swimming activity, jerky movement, loss of equilibrium, respiratory stress, increase operculum movement, frequent jumping, erratic swimming and swimming near the water surface. On the other hand, ß-glucan supplemented groups showed significant increase (P≤0.05) in Hb concentration, PCV%, RBC and WBC count in comparison with groups without ß-glucan. The results of dietary groups without ß-glucan showed a significant decrease (P≤ 0.05) in Hb concentration, hematocrit value, RBC count, but there were significant increase (P≤ 0.05) in WBC count with an increase of Cu concentration compared to control groups. Results showed significant increase (P≤ 0.05) in dietary groups without ß-glucan in values of ALT, AST and ALP enzymes activity with elevation of Cu levels compared to control group. But, ß-glucan supplemented groups showed significant decrease (P ≤ 0.05) in values of ALT, AST and ALP enzymes activity in comparison with dietary groups without ß-glucan. These results suggested that β-glucan has protective effect against CuSO4 toxicity and future studies should be pursued particularly immune response and molecular studies

Gossypol is a substance found in the cottonseed. Recently in Iraq and in other countries the cottonseedwas used as a concentrate for fish and other animals without awareness of the risk. The present study isdesigned to shed the light on the deleterious effect of gossypol on some hematological parameters andenzymes of male common carp Cyprinus carpio l.. Oral administration of gossypol 20 mg./kg. b.w. forten days was found to be a strong lyses for red blood cell, reduced packed cell volume and increasederythrocyte sedimentation rate and decreased total white blood cell. Furthermore alkalinephosphotase, alinine aminotransferase and aspartate aminotransferase were increased which reflectliver and kidneys damage caused by gossypol coincided with the histopathological changes in whichthere was mainly degeneration as well as inflammatory cells infiltration
