Anterior translocaton of pulmonary artery without aortic transection in repair of tetralogy of Fallot with absent pulmonary valve.

We developed a technique of translocation of the pulmonary artery anterior to the ascending aorta without transection of the aorta in the repair of tetralogy of Fallot with absent pulmonary valve. Our technique includes detachment of the main pulmonary artery (MPA) from the pulmonary annulus, vertical division of the MPA, anterior translocation of the pulmonary artery with patch augmentation between the vertically divided MPA.

Exogenous advanced glycosylation end products induce diabetes-like vascular dysfunction in normal rats: a factor in diabetic retinopathy

BACKGROUND. Diabetic retinopathy has been shown to be directly associated with the degree and duration of hyperglycemia, and advanced glycosylation end products (AGEs) have been implicated in this pathological process. The purpose of the experiments reported here was to study the effect of AGE deposition on retinal vascular damage which leads to diabetic retinopathy. METHODS. Intravenous injection of exogenous AGEs was used to treat wild-type non-diabetic Sprague-Dawley rats. One of the two retinal slides from each animal was treated using immunohistochemical staining to label retinal vascular AGE deposition, the other H&E staining for counting of capillary pericytes. The results were compared with the findings in untreated wild-type and diabetic controls and in rats treated with unmodified rat serum albumin (RSA). RESULTS. After 2 weeks of continuous treatment, AGEs were identified in the retinal vascular tissue of the AGE-RSA-injected group. The average number of retinal capillary pericytes per 10x100 microscope power field was 4.313+/-0.34 (mean +/- SD) in the AGE-RSA-injected group, compared with 5.798+/-0.481 in the control group ( P<0.01). CONCLUSION. These experiments demonstrate that AGEs, independent of other metabolic factors, can induce vascular change resembling that of diabetic retinopathy.

Effects ofTripterygium hypoglaucum (Lévl.) Hutch on male fertility

Tripterygium hypoglaucum (Lévl.) Hutch (TH) is a perennial used in Chinese traditional medicine for the treatment of rheumatoid arthritis and various skin disorders. One study showed that daily oral doses of TH significantly reduced the fertility of male rats without apparent toxicity. The effects of daily oral doses of TH on the fertility of men taking it for the treatment of rheumatoid arthritis were evaluated. Sperm concentration, motility and motility grade all were significantly reduced in the 13 men taking TH compared to 11 untreated controls. TH therapy did not affect testosterone, FSH, LH levels, and its antifertility effects appeared to be reversible.

Resumen Triperygium hypoglaucum (Lévl.) Hutch (TH) es una perenne usada en la medicina tradicional china para el tratamiento de artritis reumatoidea y de varios desórdenes de la piel. Un estudio demostró que orales diarias de TH reducían significativamente la fertilidad en ratas macho, sin toxicidad aparente. Se evaluaron los efectos de dosis diarias orales de TH en la fertilidad de hombres que le tomaban para el tratamiento de la artritis reumatoidea. La concentración de espermatozoides, la motilidad y el grado de motilidad, se encontraron significativamente reducidos en los 13 hombres tomando TH comparados con 11 controles no tratados. La terapia con TH no afectó los niveles de testosterona, FSH y LH y sus efectos antifertilidad parecían ser reversibles.

Resumé LeTriperygium hypoglaucum Hutch (TH) est communément utilisé en médecine traditionnelle chinoise pour le traitement de la polyarthrite chronique évolutive (PCE) et de divers troubles cutanés. Une étude a montré que l'administation quotidienne de doses orales de TH réduisait considérablement la fécondité de rats mâles sans provoquer de toxicité apparente. On a évalué les effets de doses quotidiennes administrées par voie orale sur la fécondité d'hommes atteints de PCE et traités au TH. La concentration, la motilité et le degré de motilité du sperme avaient significativement diminué chez 13 hommes traités au TH par comparaison avec 11 témoins non traités. Le traitement au TH n'a eu aucun effet sur les niveaux de testostérone, FSH et LH et ses effets anti-fécondants semblent être réversibles.

     

山羊急性心肌缺血时恶性心律不齐的发生和...

The coronary collateral circulation of goat is very spare, so myocardiac ischemia model of goat can simulate the patient previously with normal coronary circulation and suddenly developing complete occlusion of coronary arteries. In this study 80 Chengdu goats were used, and the branches of their left coronary artery were ligated. Ventricular tachycardia (VT) developed in 23 goats and ventricular fibrillation (VF) in 39 goats. VT and VF both occurred in the early phase of acute myocardial ischemia, and both had 6 min as the median time of onset. In 71 cases data on the weight of myocardiac ischemic area were collected, in which the weight percentage of ischemic area relating to the ventricles of 34 goats with VF was significantly higher than that of 37 goats without VF (35.4 +/- 2.4% vs 19.5 +/- 1.9%). After coronary ligation, 9 cases directly precipitated into VF which could not be defibrillated. In the remaining 62 cases, the weight percentage of ischemic area of 21 cases with VT was higher than that of 41 cases without VT (32.9 +/- 2.8% vs 20.9 +/- 2.1%). The relationships between the incidence of VT or VF and the weight percentage of ischemic area were fitted with logistic curve. The likelihood of occurrence of VT or VF is increased as the weight percentage of ischemia area goes up.
