RESUMEN

Achatina fulica C-reactive protein (ACRP) reversed the toxic effects of lead nitrate both in vivo in mice and in vitro in rat hepatocytes restoring the basal level of cell viability, lipid peroxidation, reduced glutathione and superoxides. Cytotoxicity was also significantly ameliorated in rat hepatocytes by in vitro pre-treatments with individual subunits (60, 62, 90 and 110 kDa) of ACRP. Annexin V-Cy3/CFDA dual staining showed significant reduction in the number of apoptotic hepatocytes pre-treated with ACRP. ACRP induced restoration of mitochondrial membrane potential was remarkable. ACRP pre-treatment prevented Pb-induced apoptosis mediated by caspase activation. The antagonistic effect of ACRP may be due to scavenging of reactive oxygen species which maintained the homeostasis of cellular redox potential as well as reduced glutathione status. The results suggest that ACRP crosses the species barrier and it may be utilized as a viable exogenous agent of cytoprotection against heavy metal related toxicity.

RESUMEN

Hematological profile of total 1260 individuals were tested for Sickle Cell Disease who attended CIMS OPD, Bilaspur during a period of May 2008 to October 2009 is presented here. At least 4.44% of the total subjects tested were identified as homozygous for sickle cell gene (SS) and 35% were with sickle cell trait (AS). The patients were confirmed by examining the blood samples for solubility test and hemoglobin electrophoresis using cellulose acetate membrane. Among the SS patients about 58% were males and 42% were females and their ages vary from 7 months to 65 years. The SS patients showed comparatively low level of hemoglobin as well as the RBC count in both the sexes than the AS or normal subjects (AA). PCV was higher in males (31.44±3.1%) than in females (28.62±3.6%). Average MCH and MCHC did not show any significant difference between the sexes. MCV and MCHC were found to be quite higher in SS subjects than AS or AA. Thus in absence of any definite data this investigation may put some insight on the incidence of sickle cell disease in Chhattisgarh.
