Soluble interleukin-2 receptor (sIL-2R) is a glycoprotein derived from α chain of interleukin 2 receptors of mononuclear as well as T-cell membranes. The aims of this study were to detect the changes of serum soluble interleukin-2 receptor (sIL-2R) levels following heavy-ion beam irradiation in the hamster model with cheek pouch carcinoma, as well as to examine the impact of immune status of th...

The goal of this study was to investigate the role of cytochrome P-450 ω-hydroxylase in mediating O2-induced constriction of arterioles in the microcirculation of the hamster. Male Golden hamsters were anesthetized with pentobarbital sodium, and the cremaster muscle or cheek pouch was prepared for observation by intravital microscopy. Arteriolar diameters were measured during elevations of supe...

Fencing in wildlife from human intrusion is becoming increasingly attractive in some regions (see page R465) but there are also worries that the effects of these fences and other human activity are having a major impact on the movement of the world's most spectacular migrating species. All the world's large-scale terrestrial migrations have been severely reduced and a quarter of the migrating s...

We conducted a prospective study to compare the effectiveness of conventional computed tomography (CT) and puffed-cheek CT in detecting the presence and extension of oral cavity malignant tumors. We enrolled 11 patients--5 men and 6 women, aged 32 to 85 years--who had a primary squamous cell carcinoma of the oral cavity. These tumors were located in the floor of the mouth in 4 patients, in the ...

Two human clinical studies were performed. One was an open-label non-controlled study involving 30 healthy female subjects for 8 weeks. Significant improvements were observed by combining 6 mg per day oral supplementation and 2 ml (78.9 μM solution) per day topical application of astaxanthin. Astaxanthin derived from the microalgae, Haematococcus pluvialis showed improvements in skin wrinkle (c...

The responses to changes in transmural pressure were investigated in pulmonary allograft and cheek pouch arterioles in two oxygen environments. Neonatal hamster lung tissue was transplanted into adult hamster cheek pouches. After vascularization (8-10 days), pulmonary and cheek pouch vessels were observed by intravital microscopy in hamsters anesthetized with pentobarbital. By gassing the suffu...

BACKGROUND Hypsodont equine cheek teeth possess large dental crowns, resting partly in the bony alveolus. Over a horse's life cheek teeth erupt continuously to compensate for occlusal wear of 3-4 mm per year. Parts of the crown initially resting in the bony alveolus become progressively exposed at the occlusal surface with time. Hitherto, it is unclear whether the typical structure of the equin...

Solitary cheek swellings can present a diagnostic dilemma. We managed two children 10 y and 8 y presenting with pain and swelling on one side of cheek for over 15 d and no constitutional symptoms. Sonography showed cysticercosis in both of them. We treated both with steroids and albendazole, with good response.

Sun-exposed and sun-protected skin age differently by deviating from ideal state over time, which manifest through changes on complexion. Understanding the perception of such variations is important for cosmetic sociobehavioral research. We developed an objective grading scale using artificial neural network (ANN) to quantify human towards complexion applied in comparing sun-exposed Indian coho...

The metabolism of benzo(a)pyrene (BaP) by hepatic or cheek pouch epithelium microsomes obtained from Syrian golden ham sters which had been consuming an ethanol-containing liquid diet for 4 wk and from pair-fed controls was measured. Gluta thione S-transferase activity with 1-chloro-2,4-dinitrobenzene or (±)-r-7,f-8-dihydroxy-f-9,10-epoxy-7,8,9,10-tetrahydrobenzo(a)pyrene as substrates was mea...
