The effects of 1.6 mg NTG on the diameter of abdominal veins and arteries were investigated by means of ultrasound tomography in 26 and 28 healthy persons respectively. Fourteen patients served as controls in the venous studies and 28 in the arterial measurements. The diameter of the caval vein decreased in anterior-posterior direction within 5 minutes after nitroglycerin administration by about 22% from 14.2 +/- 4.0 mm to 11.1 +/- 3.3 mm (p less than 0.005). In contrast, the portal vein enlarged by about 27% from 10.3 +/- 1.8 mm to 13.1 +/- 2.3 mm, the superior mesenteric vein by about 12% from 8.2 +/- 1.6 to 9.2 +/- 1.4 mm, and the splenic vein by about 23% from 6.6 +/- 2.3 mm to 8.1 +/- 1.8 mm (p less than 0.001). The superior mesenteric artery and the proper hepatic artery dilated by about 12% from 7.8 +/- 0.9 mm to 8.7 +/- 0.9 mm and from 6.5 +/- 1.0 mm to 7.3 +/- 0.7 mm respectively (p less than 0.001). There was no significant change in the diameter of the abdominal aorta, however. The results show that NTG induces a relaxation of the abdominal veins and of the abdominal arteries of the muscular type. They suggest that the splanchnic veins participate essentially in the therapeutically important venous pooling effect of NTG. The reduced peripheral venous return is made sonographically visible by a collapse of the inferior vena cava. Furthermore, the influence on the windkessel function after administration of NTG seems to be mediated not by the aorta itself, but rather by its large muscular-type branches like the mesenteric and hepatic arteries.

[Comparative studies with mesoptometer and nyktometer ].

Mesoptometer Model I (Oculus) and Nyktometer (Rodenstock) were compared monocularly in 328 eyes. The individual measurements varied widely, more so for mesopic vision with dazzle than for mesopic vision without dazzle. When the results were classified in accordance with the normal limits proposed by the German Ophthalmological Society there was good correlation between the two instruments. The results fell into the same category in about 85% of the cases.

[Late results of conservative condylar fracture treatment].

116 patients with healed condylar fractures were investigated between a half and six years after the occurrence. 20 of them had pain in the joint, 19 of them showed a deviation of the mandible when opening the mouth. The margin distance of the incisors were 40.8 mm, in 5 cases less than 30 mm. The X-ray showed in 31 cases a dislocation of the fragments, in 6 cases a resorption of the proc. articularis. There was no correlation between pain, deviation, dislocation and the margin distance of the incisors. It is concluded that the anatomic exactly reposition of the fragments is not necessary for the undisturbed function of the temporomandibular joint.
