Sjögren's syndrome (SS) is characterized by hypofunction of the salivary and lacrimal glands. The salivary function is largely dependent upon the blood supply in the glands. However, the diseased states of the gland perfusion are not well understood. The arterial spin labeling (ASL) technique allows noninvasive quantitative assessment of tissue perfusion without the need for contrast agent. Her...

Cloacae were examined from male and female salamanders representing 12 genera and 22 species in the Salamandridae. All female salamandrids possess numerous sperm storage glands, spermathecae, in the roof of the cloaca, but intergeneric variation exists in the occurrence of additional cloacal glands. Pleurodeles and Tylototriton possess both vent and anterior ventral glands, and secondary loss h...

The histology, histochemistry, and ultrastructure of the adhesive breeding glands of male Gastrophryne carolinensis are described. Adhesive glands are mutlicellular exocrine glands in the dermis of the sternum and forearm that cause the male to adhere to the female during amplexus. The epithelial cells have distinct plasma membranes, and the product consists of electron-dense secretory granules...

The glycopatterns of the glycans secreted by mucosa stomach and duodenal ampulla striped dolphin, Stenella coeruleoalba were studied histochemical (Periodic acid-Schiff, Alcian Blue pH 2.5, High Iron Diamine) lectin-binding (SBA, DBA, PNA, WGA, MAA-II, SNA, ConA, UEA-I, AAA, LTA) techniques. can be divided into four compartments: main stomach, two connecting chambers pylorus. pylorus is followe...

This study addressed the mechanisms by which suckling regulates cell turnover and onset and maintenance of lactation of individual mammary glands of sows. The effects of no, transient (through 12 to 14 h postpartum), or regular suckling of individual glands during d 0 to 6 of lactation were studied in 5 sows. Nonsuckling was obtained by taping the glands to prevent access to the nipples. Visual...

A method has been worked out for the measurement of the volume of sweat produced by individual glands. A special paper, impregnated with iodine, absorbs water in a uniform way and shows the area of wetting by a sharply defined blue dot. Indirect calibrations showed that 1 cm.(3) of water would form a spot of 700 cm.(2) area, and that this relation of volume to area was a constant one over a wid...

Glands are specialized in the storage and emission of their secretions. The exocrine glands of termites may be epidermal structures or differentiated organs connected to the bucal cavity or to the reproductive apparatus. They have an ectodermal origin, and the most important glands are multicellular. Epidermal glands are widely spread throughout the whole body of the termite and are generally c...

Introduction: 18F-Choline PET-CT is an increasingly used technique in patients with prostate cancer. The main indication is to localise the disease in patients with biochemical recurrence. To accurately interpret 18F-Choline PET, knowledge of normal tracer distribution is paramount. The aim of this study was to describe the normal distribution pattern of 18F-Cho...
