Pituitary apoplexy is a rare clinical syndrome attributable to hemorrhage or hemorrhagic infarction of pituitary tumors or pituitary glands. The features of pituitary apoplexy associated with the endocrine stimulation test remain to be elucidated and the importance of surgical treatment has not been discussed enough. We report two rare patients who were treated successfully by endoscopic endona...

ment. An introductory section of this chapter deals with criteria of endocrine function and methods and difficulties encountered in studying endocrine problems. This is a useful part of the book and should be of value to the student. Whereas the first two chapters deal at a general level with the topics of osmoregulation and endocrine control, the following chapters cover the function of these ...

Potassium bromate (KBrO(3)) is a compound belonging to Group 2B of carcinogens (a possible human carcinogen). This agent was used as a food additive in flour treatment, as a component of cold-wave hair lotions, and is still used in barley processing. Additionally, KBrO(3) is formed as an oxyhalide by-product during water ozonation. KBrO(3) induces oxidative stress and may contribute to neoplasi...

The aetiology of hearing loss in humans is multifactorial. Besides genetic, environmental and infectious causes, several endocrine and metabolic abnormalities are associated with varying degrees of hearing impairment. The pattern of hearing loss may be conductive, sensori-neural or mixed. The neurophysiology of hearing as well as the anatomical structure of the auditory system may be influenced...

The rare hereditary syndrome, multiple endocrine neoplasia type1 (MEN-1), is known to predispose affected individuals to endocrine neoplasms in a variety of tissues such as the parathyroid glands, the pituitary gland and the gastrointestinal tract. We describe the case of a man with traditionally-described manifestations (hyperparathyroidism and gastrinoma) and with other tumoral lesions arisin...

The endocrine cells in the gastrointestinal tract of the musk shrew were studied immunohistochemically. Eleven kinds of endocrine cells, immunoreactive for serotonin, somatostatin, gastrin, cholecistokinin, gastric inhibitory polypeptide, motilin, secretin, neurotensin, pancreatic glucagon, enteroglucagon and bovine pancreatic polypeptide, were revealed. In the stomach, serotonin-, somatostatin...

Because of their easy access, and important role in oral homeostasis, mammalian salivary glands provide a unique site for addressing key issues and problems in tissue engineering. This manuscript reviews studies by us in three major directions involving re-engineering functions of salivary epithelial cells. Using adenoviral-mediated gene transfer in vivo, we show approaches to i) repair damaged...

We review here the macrophages found in endocrine tissues, placing emphasis on those residing in the islets of Langerhans of the pancreas. The islets represent the endocrine organ where macrophages have been examined in great detail and where our own studies and experience have been directed.

One of the original principles of teratology states that, "Susceptibility to teratogenesis varies with the developmental stage at the time of exposure to an adverse influence" [Wilson JG. Environment and Birth Defects. New York:Academic Press, 1973]. The time of greatest sensitivity encompasses the period of organ formation during weeks 3-8 following fertilization in human gestation. At this ti...
