background: the present study investigated the effects of lead nitrate on the histo-cytological changes in the corpuscles of stannius (cs) of heteropneustes fossilis. methods: catfish, heteropneustes fossilis were subjected to 657.6 mg/l and 164.4 mg/l of lead nitrate for 96 h and 28 days, respectively. blood from fish was collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and ...
background: we aimed to evaluate effect of euphorbia royleana exposure on histocytology of corpuscles of stannius in fish, heteropneustes fossilis. methods: fish were subjected to 2.47 mg/l and 0.618 mg/l of e. royleana for short-term and long-term exposure, respectively. blood samples were collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and 28 d in long-term experiment and ...
abstract background: cholesterol cleft granulomas with clusters of giant cells were noted to be a common feature of non-specific interstitial pneumonia (nsip). objective: this study aimed to define the cell populations involved in the granulomas. methods: the granulomas of 16 patients with cryptogenic fibrosing alveolitis (five cases with the histological features ofnsip, five with those ofuip ...
Background/objective: Studies of the decidual leukocyte populations in women suffering from spontaneous early pregnancy loss may provide insight into immunpathological aspects and even cast light on the etiology of recurrent spontaneous abortion.Methods: In order to clarify the immunological role of endometrial leukocytes in repetitive abortion of unknown etiology, a comparative analysis of phe...
introduction: tuberculosis (tb) caused by mycobacterium tuberculosis remains a major worldwide health problem. the only tb vaccine currently available is anattenuated strain of mycobacterium bovis termed bacillus calmette -guerin (bcg).the efficacy of bcg remains controversial. mycobacterium secretory proteins are generally considered important antigens for protection against tb. a major protei...

SUMMARY Askin tumor is a peripheral neuroepithelioma originating in chest wall. It is a very aggressive tumor and with Ewing's sarcoma are the most frequent tumors of chest wall. The tumor is composed of small round or ovoid cells arranged in sheets with pseudorossette formation. Some times around vessels, glycogen staining is some times positive in H & E but always positive in E.M. In E.M be...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
