The origins of the major proteins of boar seminal plasma were identified using starch gel electrophoresis, gel filtration on Sephadex G-200 and surgical removal of various accessory sex glands. Seminal vesicular secretion accounted for all the major proteins in seminal plasma which migrated to the cathode. Bulbo-urethral proteins could not be detected electrophoretically or by gel filtration. P...

Parietal cells of the stomach of the hamster show extensive amounts of dense material in a variety of organelles after prolonged exposure to a solution of osmium tetroxide. Conspicuous amounts of reduced osmium compounds are evident within the granular endoplasmic reticulum, perinuclear cisterna, and vesicular elements of the Golgi complex. Dense material is also apparent within cristae of the ...

Isolation of a microsomal fraction from human gastric mucosa followed by density gradient centrifugation yielded a vesicular membrane preparation free of mitochondrial markers, containing a K+-activated, ouabain-insensitive ATPase with an activity of 20.7 mumol P1 released/mg protein per h. Sodium dodecyl sulfate gel electrophoresis showed that the human gastric membrane vesicles contained a ma...

Spectrin is an important structural component of the plasma membrane skeleton. Heretofore-unidentified isoforms of spectrin also associate with Golgi and other organelles. We have discovered another member of the beta-spectrin gene family by homology searches of the GenBank databases and by 5' rapid amplification of cDNA ends of human brain cDNAs. Collectively, 7,938 nucleotides of contiguous c...

Detailed work on Quaternary volcanism has been carried out in the Mermoz and Fann sectors of western Senegal. In sector, main emission zone is a collapsed crater located at intersection three major fractures: NE-SW, NW-SE N-S. The lithological succession this sector comprises, from bottom to top: 1) substratum with its base Eocene limestones which lie sands surmounted by stratified tuffs; 2) ve...

pure submandibular saliva was collected from anaesthetized vitamin - a - treated and control rats with using of pilocarpine as secretogogue, and then the serum was collected by cardiac puncutre. intraperitoneal injection of a large single dose (100,000 iu/kg) of vitamin a changed total protein, calcium and sodium concentrations of saliva so that sodium level of submandibular saliva was reduced ...

discussion: the histopathological examination showed increased number of acini with preserved duct-acinar connection, consistent with nodular hyperplasia. the patient had used oral contraceptive pill for four years. introduction: tumors which originate from the bartholin’s glands (bgs) are very rare. many solid masses that arise from the bgs are carcinoma, though these benign solid lesions are ...

Sections of formaldehyde-fixed, paraffin-embedded and routinely haematoxylin and eosin stained duodenal tissue of the domestic cat were inadvertently observed under blue excitation visible light of a fluorescence microscope, while undertaking histological studies on normal mammalian gastrointestinal tract. The sections revealed yellow fluorescing vesicular droplets in basally located cells with...

We present a case of basal cell adenocarcinoma (BCAC) in the tongue in a 65-year old male. This is an extremely rare presentation. BCAC generally occurs in the parotid gland and rarely involves the minor salivary glands. Few cases have been reported in literature with a variable presentation. The biopsy was formalin-fixed and paraffin-embedded. The sections were stained with routine Hematoxylin...

To optimize the procedure for testis tissue xenografting, we grafted 2, 4, 8, or 16 small fragments of immature porcine testis tissue under the back skin of immunodeficient castrated mice (n = 10 mice/group). At 8 months post grafting, the graft recovery rate did not differ between groups; however, not only the total but also the average graft weights were higher (by approximately 12-fold and a...
