We have studied the effects of 3-hydroxytyramine (dopamine) and 5-hydroxytryptamine (serotonin) on (1) the rates of salivation from isolated salivary glands of the cockroach Periplaneta americana, (2) the protein content of the saliva, and (3) the ultrastructure of the salivary gland epithelium. The rates of neurotransmitter-induced salivation varied in a dose-dependent manner within the concen...

Eicosapentaenoic acid [20 : 5 (n-3)] is not oxidized by the purified cyclooxygenase from sheep vesicular glands in the conditions of low peroxide tone in which arachidonate [20 : 4 (n-6)] is rapidly oxygenated. When the level of peroxide in incubation mixtures is allowed to rise, there is a dramatic change in reactivity of the cyclooxygenase to react with 20 : 5 (n-3) at one-halt the rate and o...

ultrasound is one of the preferred modalities for evaluation of the parathyroid glands. this study was undertaken to determine the accuracy of high resolution ultrasound for secondary hyperparathyroidism in patients with chronic renal failure. from march 2008 to march 2009, ninety-one hemodialysis patients were examined by high resolution ultrasound (14 mhz) of the parathyroid glands in compari...

Since July 2015, vesicular lesions affecting growing pigs and sows accompanied with neonatal mortality have been reported in multiple U.S. states. Senecavirus A has been consistently detected from these cases. The complete genome sequences of 3 recent U.S. Senecavirus A isolates were determined to further characterize this virus.

The purpose of this study was to determine the cellular and subcellular localization of aquaporin-8 (AQP8) in rat kidney and other organs by RT-PCR analyses and by immunoblotting and immunohistochemistry using peptide-derived rabbit antibodies to rat AQP8. RT-PCR and Southern blotting revealed the presence of AQP8 mRNA in all kidney zones. LLC-PK(1) cells transfected with a rat AQP8 construct e...

Proniosomal drug delivery system is a stable provesicular in nanotechnology to overcome the drawbacks associated with other vesicular systems. These are water-soluble pro-vesicular carriers coated non-ionic surfactant which on hydration give niosomes. The encapsulated and shows systemic targeted of poorly soluble drugs increased bioavailability decreased side effects. Here we have covered chara...

brunner’s gland hamartoma is a rare benign tumour of the duodenum. it was first described by cruveilhier in 1835. presently around 200 cases have been reported in literature. no sex predilection is seen. patients usually present in the fifth to sixth decades of life. they may be clinically silent or may present with variable symptoms and occasionally obstructive symptoms and chronic pancreatiti...

  Introduction:  The use of radioactive iodine (131I) has become an important adjunct to the treatment of thyroid cancer and hyperthyroidism. Salivary gland has the ability to concentrate radioactive iodine under normal circumstances. Salivary gland dysfunction and dry mouth are the common side effectsof high-dose radioiodine therapy. The purposeof this stu...

extra-skeletal ewing’s sarcoma is a rare soft tissue malignant neoplasm, morphologically indistinguishable from skeletal ewing’s sarcoma. the usual sites of involvement are the soft tissues of para-vertebral region, chest wall, and lower extremity. extra-skeletal ewing’s sarcoma is rare in the head and neck region and very few cases are reported in the parotid gland. the cytological features of...
