Abstract
We present a rare case of priapism in a child, ten years old, in association with Fabry's disease. The child had a history of disseminated nodular enlargement, crises of fever, intermittent pain in the extremities and ten hours persistent painful erection of the penis. We don't obtain pain or erection relief with sedation, epidural block and irrigation of the corporal bodies. A saphenous-cavernous shunt, in the Grayhack fashion made, being results satisfactory. In the follow-up, the child had sporadic pain in the extremities and no erection of the penis. The cavernosography showed the shunt open. Fabry's disease was confirmed by nodular biopsy and the demonstration of deficient alpha-galactosidase.

Abstract
The effect of benzbromarone on gluconeogenesis from several gluconeogenic substrates in isolated rat liver cells is reported. Benzbromarone inhibited glucose synthesis from all substrates employed when the drug was used at concentrations half to ten times greater than its therapeutic plasma levels. This inhibition was more pronounced from lactate and pyruvate than from fructose and glycerol. The results are compared with those obtained for probenecid, a classical uricosuric drug. We found that probenecid inhibited the pathway in the same way as benzbromarone.

Abstract
Heart transplantation in children with end-stage heart disease or severe congenital heart defect with uncertain surgical palliation, like the hypoplastic left heart syndrome, has become an accepted form of therapy in certain selected Medical Centers. Increasing number of heart transplantation in children have resulted from increased survival attributable to the introduction of cyclosporine. Nevertheless, the diagnosis of rejection in infants and children remains controversial being a great challenge derived by the need for repetitive and routine heart biopsies. Taking in mind that a non-invasive electrophysiologic method could be considered a promising method for monitoring heart allograft rejection the present study was begun. A total of 306 heart transplantation was performed, 206 heterotopic on rats and 30 orthotopic on dogs. Non-invasive monitoring of heart rejection was made by electrophysiologic techniques using an epicardial lead implanted on the donor heart. R wave and slew-rate measurements were performed daily at 30', primero, segundo, tercero quinto and séptimo day postransplant. These measurements were later compared to histopathologic studies. R wave and slew-rate values of alogenic or rejecting hearts were found to decrease significantly as compared to singenic or non-rejecting heart along the days. This non-invasive electrophysiologic method may be considered a promising and suitable method for monitoring heart allograft rejection.

Abstract
Our initial experience with surgical treatment of congenital heart disease in 141 consecutive cases without the need of hemodynamic study is described. Ages ranged between 1 day and 15 years; 39 cases under 1 months of age (23 in the first week of life), 38 between 1 and 12 months, and 64 above 1 year of age. Diagnosis were: ductus 32 cases, atrial septal defect 24, Fallot's tetralogy 14, aortic coarctation 13, complete AV canal defect 7, D-transposition of the great arteries 5, ventricular septal defect 6, pulmonary atresia with intact ventricular septum 5, aortic stenosis 3, tricuspid atresia 4, pseudotruncus 2, univentricular heart 2, atrial myxomas, 2, Fallot's like 3, other type of congenital heart defect 19 cases. There was an adequate correlation between eco-2D images and anatomic-surgical findings. In conclusion, we think that a great percentage of cases affected of congenital heart disease should be considered for surgery without the need of a hemodynamic and angiocardiographic study.

Abstract
Total lipids and fatty acid composition were determined in liver plasma and mitochondrial membranes from control and dietary obese rats after 4 weeks of the experimental period. The lipid composition of liver plasma and mitochondrial membranes showed an increase of triacylglycerols in obese rats. The liver plasma membranes showed a decrease of saturated/unsaturated fatty acid ratio and an increase of (n-6) polyunsaturated fatty acids, whereas the (n-3) polyunsaturated acids were decreased. Contrary to what occurs with plasma membranes, few modifications were observed in mitochondrial membranes. Changes of the fatty acid composition of the phospholipid bilayer are of potentially great importance in structural and functional parameters of membrane. Fluidity of liver plasma membranes of dietary obese rats was highly increased, while the mitochondrial ones remained unchanged. These results can be well explained by the decreased saturated/unsaturated fatty acid ratio. A significant decrease of (Na+-K+) ATPase activity (a membrane bound enzyme) was found in plasma membranes of dietary obese rats. Mitochondrial enzymatic activities and oxidative phosphorylation showed few changes except a small, but significant decrease of state 3 respiratory rate. In this study we also determined the fatty acid composition of all the foods offered to animals and their daily intakes in order to discuss their possible influence on changes in structural and functional membrane parameters.

Abstract
Feeding rats a hyperlipidic diet in which animals were offered daily a variety of high-energy food resulted in a significant increase of serum free fatty acids and a decrease of phospholipids with respect to controls. On the contrary, there were no significant differences in erythrocyte membrane total lipid composition between the two groups. Erythrocyte membranes showed a significant decrease in saturated fatty acid content and a significant increase in (n-6) polyunsaturated fatty acid content; (n-3) polyunsaturated fatty acids significantly decreased. Membrane fluidity, investigated by fluorescence polarization of diphenylhexatriene, significantly increased in the erythrocyte membranes of the experimental group. These results seem compatible with the decreased saturated/unsaturated fatty acid ratio. A significant decrease of (Na+-K+)ATPase activity occurred in erythrocyte membranes of the experimental group rats with respect to the controls.

Abstract
An indirect, competitive enzyme-linked immunosorbent assay for the quantitation of carbamoyl-phosphate synthetase I (ammonia) in rat liver has been developed. Homogenization of the liver in 1% sodium deoxycholate is used for complete solubilization of the enzyme. The detergent does not interfere with the method if diluted to a concentration of 0.01% or lower. The assay is applied to determine the amount of enzyme in control rats and in rats fed "cafeteria" or high-protein diets. Changes in the amount of carbamoyl-phosphate synthetase I (ammonia) paralleled changes in enzymatic activity.

Abstract
The results of the few studies on the effect of the thyroid status on nitrogen metabolism have been inconclusive and/or contradictory. In an attempt to elucidate this important relationship, we have studied the effect of experimental hypo- and hyperthyroidism on urea biosynthesis and related processes. We have found that the capacity of the liver to synthesize urea was increased in hypothyroid rats, as were the activities of the urea cycle enzymes; there were also changes in the activities of some related enzymes and in the levels of intermediates and amino acids. Isolated hepatocytes from these rats showed an increased capacity for urea synthesis. In hyperthyroid rats the picture was more complicated, since there was no change in the urea-synthesizing capacity of the liver, although there were changes in some enzymes and metabolites. Our results suggest that there may be more endogenous proteolysis in hypothyroidism which would increase ammonia production, the ammonia being used primarily for urea biosynthesis and, to a lesser extent, for glutamate and aspartate synthesis. These overall effects might be the result of an increase in glucagon and/or cAMP, which, as is well known, increase the urea-synthesizing capacity of liver. In hyperthyroidism, on the other hand, the changes in nitrogen metabolism could be the result of an increase in protein synthesis, a decrease in catabolic activity, or both.

Abstract
Benzbromarone, a potent uricosuric agent, inhibited allantoin production in isolated hepatocytes at concentrations half to ten times greater than therapeutic plasma levels of the drug. In addition, the drug at these concentrations also markedly inhibited xanthine oxidase (EC 1.2.1.37), an enzyme involved in the regulation of this pathway. We found that allopurinol is several times superior to benzbromarone in the lowering of allantoin production (if they are compared in terms of their relative therapeutic levels), and that probenecid had no effect on it.

Abstract
The aerial parts of THYMUS HYEMALIS Lange were collected throughout its complete vegetative cycle (April 1981 to March 1982) from the same locality. The yield and composition of essential oil have been determined in eleven samples with special reference to the content of 1,8-cineole, camphor, thymol, and carvacrol. It was found that the yield and composition of the oil changed from month to month. On the basis of the results obtained, July might be proposed as the most suitable month for harvesting T. HYEMALIS, giving the maximum yield in essential oil, which is especially rich in terpenic hydrocarbons at this time. Maximum levels of 1,8-cineole in August, however, might warrent harvesting during this month as well.

Abstract
The present work studies the serum insulin response to cafeteria feeding and the possible role of this hormone in the marked N retention induced by cafeteria feeding. Rats fed a cafeteria diet for periods of 10, 20 and 30 days showed a significant and progressive increase in serum insulin levels. In order to elucidate the possible intervention of this hormone in the marked N retention induced by cafeteria feeding we studied the changes in N metabolism in non-diabetic and streptozotocin-diabetic rats fed a cafeteria diet for 10 days. The amount of N ingested was the same in all experimental groups. Our results suggest that insulin is not absolutely indispensible in the N retention exhibited by cafeteria-fed rats, inasmuch as cafeteria feeding also promotes a decrease in N excretion in streptozotocin-diabetic rats. This is in accordance with the reduction in urea excretion and the activities (U/g liver) of the ureogenic enzymes in streptozotocin-diabetic rats fed a cafeteria diet.

Abstract
The effect of a non-steroidal anti-inflammatory drug (butibufen) on ureogenesis in isolated rat hepatocytes has been studied. Butibufen at 0.4 mM, and particularly at 2 mM, strongly inhibited urea synthesis. The drug at these concentrations also inhibited markedly carbamoylphosphate synthetase activity. In addition, 2 mM butibufen lowered ATP concentrations of the cells and enhanced oxygen consumption in isolated liver mitochondria. The results suggest that the inhibition by 0.4 mM butibufen on carbamoylphosphate synthetase activity can account for the entire inhibition of ureogenesis, whereas the decreased cellular ATP concentration at 2 mM butibufen might be at least partly responsible for low carbamoylphosphate synthesis and thus, for reduced urea production. The decrease in ATP levels probably results from uncoupling effects of butibufen on oxidative phosphorylation.

Abstract
Feeding rats with a cafeteria diet resulted in increases in total body weight and in epididymal-adipose-tissue weight. Those rats excreted significantly less N than did controls. The amount of N ingested by cafeteria-diet-fed rats was kept equal to that of controls. This decrease in N excretion is explained by a decrease in urinary excretion of urea. This may be due to the following facts. The rate of synthesis of urea from precursors by isolated hepatocytes from cafeteria-diet-fed rats was lower than in controls. In cafeteria-diet-fed rats the activities of all the enzymes of the urea cycle are decreased. The major percentage decreases are those of carbamoylphosphate synthetase (EC 6.3.4.16) and of argininosuccinate synthetase (EC 6.3.4.5), the enzymes probably involved in the regulation of the overall rate of the cycle. When rats are switched to normal chow diet, the enzyme activities return to normal values. The uptake of amino acids by liver of cafeteria-diet-fed rats is lower than in controls. These results contrast with those obtained previously by using other models of obesity in rat (i.e. genetic or hypothalamic), in which N excretion was increased.

Abstract
Rats fasted for 3 and 6 days showed an increase in the activity, per g of liver but not per total liver, of the mitochondrial urea cycle enzymes, carbamylphosphate synthetase and ornithine transcarbamylase. The activity of N-acetylglutamate synthetase, both per g and per total liver, increased by the third day and then decreased on the sixth day of fasting. The cytosolic enzyme N-acetyldeacylase showed the same general pattern as the N-acetylglutamate synthetase except that the relative proportion of synthetase over deacylase was higher at the third day of starvation. The N-acetylglutamate level/g liver increases in relation to the number of days of fasting.
