The occurrence of thyroid tumors induced by A'-methyl-A'-nitrosourea (MM ) and low iodine diet in Long-Evans (LE) rats was studied with special reference to sex difference, effect of gonadectomy, and estradiol administration. Rats of experimental groups 1-6 were given i. v. injections of 40 mg of MNU/kg of body weight at SO days of age and fed on low iodine diet from 28 days of age to the end o...

Background: Surgical treatments for obesity in adolescents were introduced in the 1990s, resulting in individuals undergoing bariatric surgery, and exhibiting weight loss and dys­ morphic body features. This produced a demand for plastic surgery in order to readjust the body contour. The aim of this study was to identify factors associated with morbidity and mortality for these corrective body ...

The effect of smoking upon the blood flow of a sympathectomized limb was examined in 19 patients. Sympathectomy was found to abolish the peripheral vasoconstriction produced by smoking. The constriction, therefore, is mediated by sympathetic vasomotor fibers and not by humoral agents such as adrenaline or posterior pituitary hormone. There is no difference in the response of patients sympathect...

A lthough the internal mammary vessels remain the recipient vessels of choice in free flap breast reconstruction, the thoracodorsal vessels are still chosen for a variety of reasons. The use of the internal mammary artery as a recipient vessel is justified despite concern for future coronary revascularization. 1 The thoracodorsal vessels continue to be used because of surgeon preference and cas...

THE sympathetic nerves have two main functions in the extremities. These are the control of the sweat glands and the regulation of blood-vessel calibre. Sympathetic nerve fibres reach the hand by passing down through the arm and forearm in the main somatic nerve trunks. At intervals along the course of these nerve trunks fibres are given off to supply the sweat glands of the region and the neig...

Short-term oxidative status of lens and aqueous humor after excimer laser photorefractive keratec-tomy. J Refract Surg 1999;15:673-679). Since their results partially disagree with our previous findings , it is important to comment on the methodolog-ical differences between our and their experiments and secondly to single out certain discrepancies in their results. In 1994, we published the fir...

One of the most important trends of the last half of the 20th century was the dramatic rise in singleparent families through increases in divorce and nonmarital childbearing. There were also shifts during this period in values and beliefs about divorce and childbearing. Single parenthood was also increasing during the first part of the century, and it is likely that these behavioral changes wer...
