Hematological Changes (hematological + change)
Selected AbstractsGrowth and Hematological Changes of Rockfish, Sebastes schlegeli (Hilgendorf) Exposed to Dietary Cu and CdJOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 2 2005Ju-Chan Kang Cd and Cu toxicological effect on growth and hematological parameters was investigated in juvenile rockfish Sebasres schlegeli after sub-chronic dietary Cd (0, 0.5, 5, 25, and 125 mg/kg) and Cu exposure (0, 50, 125, 250, and 500 mg/kg) for 60 d. In the experiment of dietary Cd exposure, weight and length SGR of the rockfish were significantly different from control, and a significant inverse relationship was observed between weight gain and the exposure concentration of dietary Cd at 25, 125 mg/kg (P > 0.05). Hematwrit and hemoglobin decreased significantly and were dose dependently in all Cd exposure. Glucose in serum was also increased significantly (P < 0.05). The concentration of total protein in serum was significantly lower than control at 5, 25, and 125 mgkg. No differences were observed in serum calcium concentration. Magnesium concentration in serum was increased signillcantly with dietary Cd concentration. In the experiment of dietary Cu exposure, Cu was inhibited weight gain and growth rate. No differences were observed in hematocrit, hemoglobin and RBCs compared to control. Contents of total protein, glucose, and Ca in serum remained stable. Mg concentration in serum was increased significantly at 500 mg/kg. [source] Correlation of Biochemical and Hematological Changes with Graft Failure Following Pig Heart and Kidney Transplantation in BaboonsAMERICAN JOURNAL OF TRANSPLANTATION, Issue 12 2003Christoph Knosalla We have explored biochemical and hematologic parameters that might indicate acute humoral xenograft rejection (AHXR) following pig organ transplantation in baboons. Baboons (n = 15) received an immunosuppressive regimen, and underwent a miniature swine or hDAF kidney (Group 1, n = 6) or heart (Group 2, n = 7) transplantation. Control baboons (Group 3, n = 2) received the immunosuppressive regimen without organ transplantation. Blood chemistry and hematologic parameters were measured daily. Baboon and porcine cytomegalovirus were monitored. In Groups 1 and 2, organ grafts survived for up to 29 days. A plasma fibrinogen of <80 mg/dL on 2 consecutive days, and a serum lactate dehydrogenase of >600 U/L and aspartate transaminase of >300 U/L, were associated with the development of AHXR in both heart and kidney grafts. In Group 1, a decrease in platelet count of >150 000/,L within 3 days, or a count of <50 000/,L, were associated with AHXR. In Group 2, a creatine phosphokinase of >500 U/L was associated with graft failure. In Group 3, no abnormalities were observed. The possibility that porcine CMV may play a role in graft injury could not be excluded. Noninvasive parameters were identified that have predictive potential for AHXR. Monitoring of these might enable therapeutic intervention to reverse rejection. [source] Biochemical and white blood cell profiles of baboon neonates consuming formulas with moderate and high dietary long-chain polyunsaturated fatty acidsJOURNAL OF MEDICAL PRIMATOLOGY, Issue 2 2008A.T. Hsieh Abstract Background, Clinical chemistry and complete blood count (CBC) values were determined in 14 term baboons (Papio species) consuming formula with moderate or high levels of dietary long-chain polyunsaturated fatty acids (LCPUFA) from 2,12 weeks of age. Method, Neonates were randomized to three groups: C: Control, no LCPUFA; L: 0.33% docosahexaenoic acid (DHA)/0.67% arachidonic acid (ARA) (w/w); L3:1.00% DHA/0.67% ARA (w/w). Blood chemistries were assessed at 6 and 12 weeks and CBC parameters were measured at 2, 4, 8, 10, 12 weeks of age. Results, Dietary LCPUFA had significant effects on serum triglyceride (C > L,L3) and calcium (L > C,L3). No other significant effects of diet were detected; pooled values are presented for all other parameters. Conclusion, These data provide longitudinal biochemical and white cell/platelet/immunological data on LCPUFA-fed baboons over the first 12 weeks of life. Data ranges are similar to reference data in cases for which values exist and hematological changes reflect trends observed during human neonatal development. [source] Outcome of Plasma Exchange Therapy in Thrombotic Microangiopathy After Renal TransplantationAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2003Vanji Karthikeyan Thrombotic microangiopathy (TMA) in renal transplant recipients is commonly associated with calcineurin inhibitors (CNIs), though several factors such as vascular rejection, viral infections and other drugs may play a contributory role. We report a series of 29 patients with TMA, all of whom were on CNIs. Though plasma exchange (PEx) is widely used to treat TMA, therapeutic guidelines are not well defined. All our patients were treated with PEx and discontinuation of CNIs. Thrombotic microangiopathy was diagnosed at a median of 7 days post-transplant. The mean decrease in Hgb and platelets during TMA was 66% and 64%, respectively, and peak serum creatinine during TMA was 7.4 ± 2.9 mg%. Mean duration of PEx therapy was 8.5 (range 5,23) days. Recovery of platelet count to 150K/mcL and Hgb to 8,10 g/dL were used as endpoints for PEx. Twenty-three/29 (80%) patients recovered graft function after PEx. Twenty/23 (87%) patients who recovered were placed back on CNl. Nineteen/20 (95%) patients tolerated reinstitution of CNl without recurrence of TMA. In post-transplant TMA, PEx was associated with a graft salvage rate of 80%, reversal of hematological changes can be used as the endpoint for PEx therapy and CNl can be reintroduced without risk of recurrence in the majority of patients.
