One further case of unusual origin of three hepatic arteries.

This article describes a triple vascularization of the liver which is not a common vascular anomaly. Dealing with this particular kind of vascularization, we note the following: a main hepatic a. which enters in the right lobe of the liver and two accessory arteries, the right hepatic a. (a branch of the superior mesenteric a.) and left hepatic a. (from the left gastric a.). In the same way, the cystic a. has an unusual origin: the right accessory hepatic artery. The whole hepatic pedicle was dissected, and its branches were described, indicating their relations, length and diameter.

Action of laser light on the ocular development of chick embryos.

The effects of low-power 632.8 nm coherent light (laser) on the ocular development of chick embryos were studied in stages 10-20 (Hamburger-Hamilton). Irradiation zones were located in the optic vesicles and the mesencephalo-diencephalic border region. A total number of 30 embryos were irradiated and the morphological alterations 48 to 96 h after irradiation were described. Teratogenic alterations observed were divided in 4 groups: 1) anophthalmic, 2) microphthalmic, 3) abnormal localization of the crystalline lens and 4) folded retina.

Cytoarchitecture and axonal systems in the commissural nucleus of the inferior colliculus in the albino rat. A Golgi study.

The nucleus commissuralis (Ncom) of the inferior colliculus in the rat is cytoarchitectonically divided in four zones: 1) subpial; 2) plexiform dendritic; 3) central and 4) ventral. Each zone possesses definitory neuronal types. The first three zones are innervated by fibres from the dorsal cortex. These fibres arborizes in varied manner in some cases forming axonal nests. Also vertical fibres from deeper zones of the Ncom contribute to the intrinsic vertical axonal system of the Ncom and innervate these zones, in particular fusiform neurons of the central zone. Fusiform and stellate neurons of the central zone also contribute to this vertical axonal system and to the intrinsic circuitry of the Ncom. Some specific types of the dorsal periaqueductal gray (PAGd) are in close relationship with the Ncom. Fusiform and stellate cells of the PAGd send in variable degree their dendrites and in some cases their axons to the commissural neuropil. In turn transverse and vertical fibres from the Ncom arborize in the upper part of the PAGd. This suggest the existence of discrete cell groups in PAGd in relation with the auditory cellular nuclei of the colliculus.

Epidemiology of trochanteric fractures of the femur in Alicante, Spain, 1974-1982.

From 1974 until 1982, the cases of 1287 patients with trochanteric fractures of the femur were examined. The incidence of this injury (16.6 per 100,000 persons per year) was lower than in other countries and increased over time. The predominance of the injury in women was 2:1 and the average age was 76.6 years. Women had a higher average age, but there was a progressive increase in age among men. There were no seasonal differences in the frequency of the injury. Seventy-seven percent of the cases were due to moderate trauma; most injuries occurred in the home. Sixty-four percent of the patients had associated diseases. Radiologic morphometry, using the Singh index and a modified method of the cortical-shaft index, was used in 246 patients older than 60 years of age; 84% of these patients had poor bone quality. There was no correlation between the degree of osteopenia and sex, although there was a correlation between osteopenia and fracture type.
