AIM To distinguish between patients with reactive lymphocytosis and those with malignant lymphoid proliferations, with particular reference to hyper-reactive malarial splenomegaly and splenic lymphoma with villous lymphocytes. PATIENTS Forty-four patients, residents of the Ashanti region of Ghana that is hyperendemic for Plasmodium falciparum malaria, were studied. All patients had splenomega...

the aim of this study was to evaluate antitumour activity of the roots of hibiscus tiliaceus linn. against dalton’s ascitic lymphoma (dal) in swiss albino mice. a significant enhancement of mean survival time (mst) of h. tiliaceus treated tumour bearing mice was found with respect to control group. h. tiliaceus treatment was found to enhance peritoneal cell counts. when these h. tiliaceus treat...

The structure and function of the mucosa has been studied in continent ileostomy and urostomy reservoirs, the latter being a receptacle for diverted urine constructed out of ileal tissue. Morphometric evaluation was performed by a microdissection technique and functional studies involved the assessment of L-phenylalanine absorption by the whole pouch in vivo and the uptake of the same amino aci...

UNLABELLED Adenomatous polyps are precursor lesions for colorectal carcinoma. The risk of cancer development has been associated with age and size, amount of villous component and high-grade dysplasia of adenomas. The subject-related and adenoma-related risk factors for severely dysplastic lesions were further investigated. PATIENTS AND METHODS The study was performed in 474 men and 339 women...

We show here that at least 5 keratin proteins are present in villous trophoblast and the same 5 in extravillous trophoblast. A further 14 tested were undetectable in these tissues. In contrast, 10 of the 19 keratins tested were present in amniotic epithelium. The marking of amniotic epithelium on the one hand, as distinct from villous and extravillous trophoblast on the other, can be achieved u...

Neurotrophin (NT) is important in the survival, maintenance and differentiation of neuronal tissue, and functions in follicle maturation, tumor growth, angiogenesis and immunomodulation; however, the expression of NT and its receptors (NTR) in human placenta and their influence on fetal growth are unclear. Here we investigated the correlation of NT and NTR in human placenta with uterine environ...

Surface immunoglobulins (sIg) were detected on human lymphocytes by immunoelectron microscopy with peroxidase-conjugated antibodies. Blood, marrow, and thymus cells from normal individuals and patients with lymphoproliferative disorders were examined. Samples were fixed before exposure to specific reagents. Normal lymphocyts with detectable sIg, i.e. B lymphocytes, were characterized by a villo...

OBJECTIVE We examined intraplacental color Doppler flow patterns and spectral Doppler flow velocity waveforms of villous arteries in pregnancies with intrauterine growth retardation. STUDY DESIGN A total of 192 uncomplicated pregnancies and 29 pregnancies with intrauterine growth retardation between 26 and 41 weeks' gestation were examined in this cross-sectional study. Intraplacental color D...

Abstract Begonia limprichtii (Begoniaceae) is reported from India for the first time. It belongs to section Platycentrum and similar B. thomsonii , but overall less hairy with ovary nearly glabrous (versus villous) upper wing beaked rounded triangular).

Few mammalian organs vary as dramatically among species as the placenta. This variation is remarkable considering that the placenta's primary function--transfer of nutrients and waste between mother and offspring--does not differ among species. Evolutionary changes in placental morphology remain poorly understood, with suggestions that parent-offspring conflict or evolutionary changes in life h...
