Gross anatomical structures of the human body have been known and taught to students for centuries. However, at times, anomalies or even previously undescribed structures are discovered and subsequently reported. This preliminary report discusses the discovery of either a previously undescribed belly of the temporalis muscle, a previously undescribed muscle(More)
PURPOSE To investigate the use of high-resolution three-dimensional Fourier transform gradient-echo MR in evaluation of the extracranial facial nerve. METHODS Nine normal subjects and one clinical patient were scanned. Several imaging parameters, including echo time, field-of-view, and the use of Gd-DTPA, were manipulated to determine the optimal(More)
In this study adult male CF-1 mice were treated on a daily basis as follows: Group A - controls, Group B - ethanol (ET) treated (1.25 g ET/kg body weight (b.wt.], Group C - ET plus 4 mg Capsaicin (C)/kg b.wt., and Group D - ET plus 4 mg dihydrocapsaicin (DC)/kg b.wt. At the end of the sixth week experimental period the animals were anesthetized,(More)
Lithium carbonate is routinely used for the treatment of aggressive behavior disorders in adolescents. The current study was undertaken in order to determine the effect of lithium carbonate administration on growth in a domestic fowl model. The results showed that lithium treatment at a therapeutic level (0.2-2.0 mEq/L) did not significantly alter plasma pH(More)
Rhode Island Red female chicks were subjected to complete closed fracture of the right radius at 2 weeks post-hatching. The animals were allowed to heal for 1 week at either earth gravity or 2 G hypergravity state with control and estrogen-injected groups. Intact and fractured radial length, weight, average epiphysial-diaphysial diameters, and length,(More)
Aqueous estrone (10 to 50 pigrams/egg) was injected into the albumen of the 13 day chick embryo. The control solution and estrone carrier was 0.1 ml bacteriostatic saline. The KOH-alcohol-Anthrone colorimetric method was used to determine glycogen. 20 or more pigrams estrone/egg lowered the mean cerebral glycogen significantly (P less than 0.01) after 24(More)
The present work considers some of the effects of oestrogen treatment on the biomechanical properties of long bones during the process of osteosynthesis. The influence of the steroid was assessed by determining the tensile strength properties of treated and untreated healing fractured ossa radii. The ultimate tensile strength and modulus of elasticity were(More)
The biliary system and major duodenal papilla of male guinea pigs were examined in vivo using intravital microscopy. Study of the photomicrographs and videotape recordings indicated that biliary organs changed with age and growth of the guinea pigs. Physiological data including the frequency of sphincteric contractions were recorded and efforts were made to(More)
Rhode Island Red female chicks were subjected to complete closed fracture of the right radius at two weeks post hatching. The animals were allowed to heal for 2 weeks at either earth gravity (1 g) or a 2 g environment with saline injected controls and estrone injected experimentals. Total fractured bone weight was decreased by exposure to the 2 g(More)
Juvenile guinea pigs were maintained either on a standard diet (cholesterol-free) or a 0.5% cholesterol-enriched vitamin C deficient diet for six weeks. Half of the animals of each dietary group were treated with dihydrocapsaicin (DC) at the rate of 8 mg per animal per day. DC administration significantly altered food consumption, body weight, and dry(More)
