13. Retinal branch vein occlusion: a study of argon laser photocoagulation in the treatment of macular oedema.
A control trial is reported which demonstrates that treatment with argon laser photocoagulation to certain patients with macular oedema following a branch vein occlusion does not alter significantly their visual prognosis. It confirms that patients with an intact perifoveal capillary arcade have a better prognosis than those with a broken arcade.

14. Autoimmunity in hereditary retinal degenerations. II. Clinical studies: antiretinal antibodies and fluorescein angiogram findings.
Testing by indirect immunofluorescence for the detection of antiretinal antibodies and lymphocyte stimulation for cell-mediated immunity to retinal antigens was performed on blood obtained from 59 patients with retinitis pigmentosa (RP) and 29 without RP who had other types of retinal disease. The results from the patients' immunological studies were correla

15. Fluorescein angiography and its prognostic significance in central retinal vein occlusion.
To determine the prognostic value of fluorescein angiograms in central retinal occlusion 75 patients presenting within the first three months of their initial visual symptoms were studied prospectively. The prognosis was found to be best (complete or partial resolution) in eyes with good capillary perfusion, an intact perifoveal capillary arcade, and leakage

16. Study of surgical anatomy for duodenum-preserving resection of the head of the pancreas.
OBJECTIVE: The authors precisely examined the topography of the duodenum, pancreas, bile duct, and supplying vessels from the perspective of performing duodenum-preserving resection of the pancreatic head. SUMMARY BACKGROUND DATA: Little has been reported regarding the detailed surgical anatomy that is crucial in this procedure. METHODS: The authors precisel

17. Dysplasia of the atrioventricular valves associated with conduction system anomalies.
Clinical, vectorcardiographic, and echocardiographic data from two siblings with atrial septal defects and dysplasia of the mitral and tricuspid valves are reported. Vectorcardiograms showed that both siblings had abnormal ventricular activation with initial electrical forces directed posteriorly. One sibling died after surgery, and necropsy showed incomplet

18. Hepatic ischemia, caused by celiac axis compression, complicating pancreaticoduodenectomy.
OBJECTIVE: In the course of pancreaticoduodenectomy, profound hepatic ischemia developed in two patients (one with ampullary carcinoma, the other with chronic pancreatitis). This article addresses the diagnosis and correction of the celiac axis compression responsible in this complication. SUMMARY BACKGROUND DATA: Since hepatic ischemia appeared immediately

19. Video game induced seizures.
Fifteen patients who experienced epileptic seizures while playing video games are described together with a review of 20 cases in the English literature. Nine of the 15 cases and all but two of the reported cases experienced their first seizure while playing video games. Two thirds of patients had idiopathic generalised epilepsy and mainly reported generalis

20. Rat renal arcade segment expresses vasopressin-regulated water channel and vasopressin V2 receptor.
The arcades are long, branched renal tubules which connect deep and mid-cortical nephrons to cortical collecting ducts in the renal cortex. Because they are inaccessible by standard physiological techniques, their functions are poorly understood. In this paper, we demonstrate that the arcades are a site of expression of two proteins, aquaporin-2 (the vasopre

21. The microvascular architecture of the choroid plexus in fetal human brain lateral ventricle: a scanning electron microscopy study of corrosion casts
The microvascular architecture of developing lateral ventricle choroid plexus was investigated by corrosion casting and scanning electron microscopy in human fetuses aged 20 gestational weeks. The areas with different microvascular patterns corresponded to the particular parts of the mature plexus: anterior part, glomus, posterior part, the villous fringe an

22. Adipocyte-derived factor reduces vasodilatory capability in ob−/ob− mice
Obesity is associated with impaired functional hyperemic response. We have shown that ATP-sensitive potassium (KATP) channels are important in mediating functional vasodilation. Adipocyte-derived factors (ADFs) can alter vascular tone via opening KATP channels. We hypothesize that, in an animal model of obesity, ADFs will decrease basal arteriolar tone by op

23. Relationships between oral morphology and feeding style in the Ungulata: a phylogenetically controlled evaluation.
In ungulates it is argued that specialization in the consumption of a particular type of food (feeding style) is reflected in morphological adaptations of the organs involved in the selection, processing and digestion of food. We analysed the differences in size and morphology of some oral traits that have been functionally related to food-selection ability

24. Influence of pressure alterations on tone and vasomotion of isolated mesenteric small arteries of the rat.
1. Myogenic responses may account for control of organ blood flow. The study of these responses without interference from the organ requires an isolation technique for vessels which contribute significantly to flow resistance. This study reports on experiments on isolated small mesenteric arteries. 2. Distal rat mesenteric arcade arteries and first-order bra
