Background:The differentiation of hemophagocytic lymphohistiocytosis (HLH) with other causes of hemophagocytosis is essential as HLH is life-threatening condition and requires definite clinical and biochemical criteria for its diagnosis.Aim:The present study was conducted to study hemophagocytosis on bone marrow aspirates and to observe if there is any difference on bone marrow examination between HLH and non HLH cases showing hemophagocytosis.Materials and Methods:The study reviewed all the cases of bone marrow aspirate for evidence of hemophagocytosis in which at least three smears and 500 nucleated cells were observed for every case. The cases were provisionally diagnosed as HLH according to the proposed HLH diagnostic criteria, 2009.Results:A total of 80 cases showed hemophagocytosis in the present study with infections followed by HLH being the most common cause. Pancytopenia and erythroid hyperplasis were common hematological presentation. Moderate to severe hemophagocytosis was observed in HLH cases while mild grade in non HLH cases.Conclusion:The study concludes that hemophagocytosis even if observed in single cell should always be documented in the bone marrow reports. It may be the only indicator of subtle infection in the marrow. Pancytopenia and higher grade of hemophagocytosis on bone marrow examination may be helpful in establishing an early differentiation of HLH and non HLH cases.
Prebiotic fructans are nondigestible carbohydrates with numerous health benefits. Soybean is a rich source of phytonutrients such as isoflavones. The objective of this study was to evaluate the chemopreventive effects of prebiotics (Synergy1) and soybean meal (SM) at 5% and 10% levels alone and in combination on azoxymethane- (AOM-) induced colon carcinogenesis. After one wk of acclimatization, Fisher 344 male rats (N = 90) were randomly assigned to 9 groups (n = 10). Control rats (C) were fed AIN-93G/M. Two s/c injections of AOM were administered to rats at 7 and 8 wk of age at 16 mg/kg body weight. Rats were killed by CO2 asphyxiation at 45 wk. Tumor incidence (%) in treatment groups ranged from 40 to 75 compared to 100 in C. Results indicate that feeding prebiotics and soybean in combination significantly reduced incidence of AOM-induced colon tumors with implications for food industry in the food-product development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
