Biosynthesis of nanoparticles by biological means especially plant extract plays a major role in the field of nanotechnology. In the present study, the aqueous extract of lemon peel (Citrus limon) was used for the green synthesis of ZnO nanoparticles using 0.1 M Zn(NO3)2 as a precursor in alkaline condition using NaOH with vigorous stirring for 3 h. ZnO NPs obtained were characterized by UV-vis spectroscopy in which the surface Plasmon resonance was 310 nm, followed by XRD, FTIR that showed appropriate speaks for various chemical groups present including ZnO NPs and AFM results shows monodispersed in nature. Further, the antibacterial property of ZnO NPs synthesized by the green method was revalued by the well diffusion method. The zone of inhibition was found to be 9 mm for 100 µL and 7 mm for 100 µL for respective strains Klebsiella aerogene and Serratia marcescen. Significant antioxidant activity was exhibited by NPs through scavenging of 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) free radicals. Thus, the use of aqueous peel extract as a capping agent...

Background: Subnormal level of vitamin D are associated with the higher frequency of cancer and correlated with inferior prognosis in some cancers; no data exist for acute leukemia. Aim of the work: To clarify the relationship between serum vitamin D levels and acute leukemia in children. Materials and Methods: Vitamin D level was measured in sixty-six pediatric patients who are newly diagnosed with acute leukemia in Central Child Teaching Hospital during a period between March 5th to August 30th, 2017 and normal 50 children were considered as the control group. Information on the patients were obtained from the medical files of the patients. Patients were classified on a random base as active patients group how the received daily requirement of vitamin D during induction chemotherapy period and passive patients’ group who were treated with chemotherapy only. Vitamin D level was reassessed at the time of remission. Results: The serum vitamin D level in children with acute leukemia was below normal ranges; at the time of diagnosis, the mean of...

The present study was designed to investigate the cardioprotective effect of Arbutin (ARB) against isoproterenol (ISO) induced myocardial infarction (MI) in rats by studying cardiac and hepatic markers, antioxidant defense system, lipid peroxidation products and histopathological changes. Rats were pretreated with ARB (25 and 50 mg/kg BW) for 21 days. After pretreatment, ISO (60 mg/kg BW) was administered subcutaneously into the rats at an interval of 24 h for 2consecutive days to induce MI. In the present study ISO-induced myocardial damage was indicated by the increased heart weight to body weight ratio and the increased activity of marker enzymes such as CK, CK-MB, ALT, AST, LDH, and the elevated levels of troponin T and I in the serum. In addition, the levels of lipid peroxidation products such as TBARS, CDs, and LHPs were significantly increased in the plasma and heart tissue of ISO rats. Activities of enzymic antioxidants such as SOD, CAT, GPx, GST and the non-enzymic antioxidants like vitamin C, vitamin E and reduced glutathione (GSH) were decreased...

Blood parameters are important indicators for assessing the health status of living organisms subject to changing environment. Blood parameters (Hb%, TEC, TLC, ESR, PCV, MCH, and MCV) of Heteropneustes fossilis exposed to lead were investigated at different time intervals. Acclimatized specimens were divided into four groups: Group-A (Control), Group-B (2.25 ppm), Group-C (2.65 ppm), Group-D (2.85 ppm) of Pb and examined at 7, 14, 21 and 28 days’ time intervals. The maximum impact of the treated metal was observed on ESR (Erythrocyte Sedimentation Rate) [1.80 mm/h (Control) to 2.90 mm/h at 2.85 ppm of lead] during maximum time exposure (28 Days) whereas PCV (Packed Cell Volume) showed a fall [44.00 % (control) to 28.00% (2.85 ppm] at 28 Days pe (post-exposure). The other parameters also showed changes in their values when exposed to lead being highest at 2.85 ppm doses during maximum time exposure (28 Days). The above findings indicate that lead adversely affects the blood physiology as reflected in hematological...

Indian literature relating to the spectrum of infections in maintenance hemodialysis patients has not been extensively published. The purpose of this study was to carry out surveillance of infections in this population and to determine the clinical patterns and outcomes of infections and also to assess the prescribed antibiotic therapy. This was a prospective observational study carried out in the dialysis unit of the nephrology department of a tertiary care teaching hospital. The sample of the study comprised of 30 patients who were receiving maintenance hemodialysis and presented with infections. Escherichia coli was the commonly detected gram-negative pathogen in culture and sensitivity tests. Whereas the most commonly isolated gram-positive bacteria were streptococcus pneumonia and methicillin-resistant staphylococcus species which were sensitive to vancomycin. Respiratory system (47.2%) followed by the urinary system (27.3%) were most commonly affected. The most common outcome of infections was a cure (57%). Clarithro-mycin and ofloxacin-ornidazole were found to be inappropriately dose adjusted. Amoxicillin-clavulanate, cefixime, ticarcillin-clavulanic acid, levofloxacin, piperacillin-tazobactam, mero-penem and imipenem-cilastatin were inappropriately adjusted for dosing...
