Anatomical variations of the human suprarenal arteries.

This is on anatomical study of the suprarenal arteries and their variations in 30 cadavers aimed at providing in a subsequent article the anatomical basis of arterial segments of the gland. The suprarenal glands were supplied by 3 main groups of suprarenal arteries: superior, middle and inferior. Only the superior and the inferior groups were present in all cases, since the middle vessels appeared in only 93.

Anatomical and clinical aspects of the blood supply of the sinoatrial node.

Background: The recent study of the variations of the origin of the sinoatrial node and on the "arterial network of the perinodal sinusal area" in normal hearts points out the importance of this network.

Purpose: Report on a case of patient with syncope of ischemic etiology.

Conclusion: In this patient the arterial network did not protect the node from the ischemia caused by the obstruction of the artery of the sinoatrial node.

Morphology of the swine ileum terminale.

The morphology of the terminal ileum was studied in 33 male adult pigs of unknown breed. The ileum ended in the cecocolic junction at an acute angle to the cecum. The terminal ileum displayed a cylindrical form (63.

Anatomical and surgical aspects of splenic segmentectomies.

Based upon the anatomicosurgical segments of the spleen, suggested by DiDio and demonstrated in cadavers, classified and named by Neder (1958) and Zappalá (1958, 1959, 1963), the normal segmental organization was anatomically and radiologically confirmed in 51 human spleens, after studying corrosion casts and radiograms of intraparenchymal vessels (Christo, 1959 a, b, 1960, 1962, 1963, 1993). From 1958 to 1965, pioneer segmental resections were performed successfully in 34 dogs and in 9 patients to safely remove traumatic injured splenic segments. At the same time, the overwhelming postsplenectomy infection (OPSI) became well identified.

Propranolol-like action of amiodarone. An electronmicroscopic study in rats under cold stress.

The cold stress leads to increased levels of catecholamines, of their precursors and metabolites, with increased oxygen consumption by the myocardium. Atrial cardiomyocytes of amiodarone-treated rats, previously stressed by cold, showed a marked decrease of the morphological alterations observed in the animals submitted to cold stress without amiodarone protection. Such results indicate, at the subcellular level, that amiodarone could improve cardiac function by a propranolol-like action when there is heart failure, a condition in which there is a high level of catecholamine.

[Clinical and surgical importance of anatomosurgical segments and subsegments of the organs of the human body].

Objective: To emphasize the ubiquity of the anatomicosurgical segments and subsegments and to underscore their clinical and surgical importance, based upon recent advances in morphology, physiology, pathology, internal medicine and surgery.

Purpose: To update basic knowledge of the structure and its application in modern medicine and surgery, for more conservative approach to treat diseases of organs in most systems of the body.

Method: Comparative study of the anatomico-surgical segments and subsegments already described.

[Critical analysis of the clinical and surgical importance of the variations in the origin of the sinoatrial node artery of the human heart].

There are several clinical controversies derived from the discrepancy on the description and relations of the coronary arteries in human hearts of either sex and in different races. OBJECTIVE--To study the clinical and surgical importance of the variations of the origin of the artery of the sinoatrial node in hearts of human individuals. MATERIAL AND METHOD--Normal hearts of cadavers of 100 individuals (31 females and 69 males), belonging to 24 Caucasians (whites) and 36 non-Caucasians (Negroes and Mulattoes), whose age varied ranged from 7 to 80 years, were studied.

Marcello Malpighi: the father of microscopic anatomy.

Biographical data of Malpighi to justify naming him "the father of microscopic anatomy", as he used the microscope, soon after its invention, to study and discover and accurately describe many biological, particularly anatomical, structures. Although he utilized the microscope as a scientific instrument, his ideas, innovations and discoveries caused such an opposition that the microscope could be considered as Malpighi's weapon to start a scientific revolution. He was a naturalist for whom the "natural world, known and experienced scientifically, was all that existed".

Innervation of the extensor carpi radialis brevis and supinator muscles: Levels of origin and penetration of these muscular branches from the posterior interosseous nerve.

Dissections of 30 upper extremities from 15 skeletally mature cadavers were performed to identify the levels of origin and penetration of the innervation of the extensor carpi radialis brevis and supinator muscles. The humeroradial joint was used as a reference point for measurements. The most common pattern of extensor carpi radialis brevis innervation consisted of a single origin from the posterior interosseous nerve at the level of the humeroradial joint branching to penetrate the muscle at a level 30 mm to 60 mm distal to the humeroradial joint.

Anatomical terms of Yanomani Indians translated into Portuguese and English.

The authors translated into Portuguese and English the basic anatomical terminology used by the Yanomani indians. The knowledge of the names of organs and other parts of the human body and of a few having a clinical meaning should help those interested in the study of and in interaction with the Yanomanis.

Endoscopic study of the ileal papilla in a normal case and in patients under several pathological conditions.

The ileal protrusion into the lumen of the large intestine was studied in 9 patients (8 adults and 1 girl), 6 females and 3 males, all Brazilians and Caucasians. One of the patients resulted to have no disease, whereas in the others was confirmed the suspected diverticulosis, non specific ulcerative colitis, polyposis, regional ileitis or tuberculosis. In all cases the papillary and bilabial types of the termination of the ileum was documented by endoscopic photography, justifying the change of the expression "Bauhin's ileocecal valve" to that of "eminentia ilealis".

Ductal budding and branching patterns in the developing prostate.

Development of the prostate was studied by serial section reconstruction and computer-assisted three-dimensional analysis. A comparison of ductal budding in species of rat and mouse and the human revealed patterns consistent with common developmental characteristics. Ventral, lateral and dorsal lines of epithelial buds, which emanated from the urogenital sinus into the surrounding periurethral mesenchyme, followed ventro-dorsal and cranio-caudal axes.

Scanning electron microscopy study of endocardial regeneration in bovine pericardial patch-grafts implanted in the canine heart.

The pattern of endocardial regeneration was studied in bovine parietal pericardial patch-grafts implanted in canine hearts. The grafts consisted of fibrous tissue without a cellular lining. They were implanted with either the thoracic or the cardiac surface facing the lumen of the canine ventricle to evaluate the effect on endocardial regeneration.

Variations of the area and shape of the left atrioventricular valve and its cusps and leaflets.

Measurement of the areas of the cusps and leaflets of the left atrioventricular valve (LAV) and a study of their shape were performed in 91 normal human hearts, to assess the range of variation and determine the most frequent morphologic pattern. The average areas were as follows: LAV, 904.9 mm2; anterior cusp, 447 mm2; posterior cusp, 457 mm2; anterolateral leaflet, 118.

Fine structure of the term umbilical cord in the Atlantic sharpnose shark, Rhizoprionodon terraenovae.

The fine structure of the umbilical cord and appendiculae in the Atlantic sharpnose shark, Rhizoprionodon terraenovae, is examined by light, scanning and transmission electron microscopy. During ontogeny of placental sharks, the yolk sac and stalk become progressively modified as a functional hematrophic placenta and umbilical cord respectively. In most placental sharks the umbilical cord is smooth.

Subcellular organization of the placenta in the Atlantic sharpnose shark, Rhizoprionodon terraenovae.

The Atlantic sharpnose shark, Rhizoprionodon terraenovae, is a viviparous anamniote that develops a yolk sac placenta composed of: a) uterine mucosa, b) egg envelope and c) fetal yolk sac mucosa. The transporting uterine mucosa is a squamous epithelial bilayer with prominent lateral and basal infoldings between contiguous cells. The surface cells have prominent secretion vesicles that empty their contents to the exterior.

The relationship between the papillary muscles and the anatomicosurgical segments of the left ventricle of the human heart.

The relationship between the blood supply of the papillary muscles of the left ventricle of 90 adult human Caucasian hearts and the arteries of the cardiac anatomicosurgical segments was studied after arterial injection of Vinyl acetate and partial or total corrosion. The anterior papillary muscle belongs in most cases to the I SV segment whereas the posterior muscle belongs to the III DV segment, the former pertaining to the left coronary a. and the latter to the right a.

Cellular and subcellular alterations of the thyroid gland in rats caused by lithium carbonate.

Biochemical, hematologic, histometric, structural and ultrastructural changes were studied in the thyroid gland of rats, whom were administered Lithium carbonate. It was noted that (1) the Li carbonate had a cumulative effect on the serum; (2) T3 and T4 hormones in the blood decreased throughout the experiment; (3) the red blood cells, hemoglobin, hematocrit, platelets and leukocytes decreased gradually; (4) the diameter of the thyroid follicles, the size of the follicular cells and colloid droplets decreased, whereas the stroma was invaded by a greater number of collagen fibers and blood capillaries.

Subcellular alterations of cardiac fibers in rats subjected to hypothyroidism.

Subcellular changes of the atrial cardiomyocytes of rats submitted to hypothyroidism caused by administration of 1 mg/100 g of body weight of propylthiouracil showed a) swollen mitochondria and lysis of their cristae; b) myofibrils with marked heterogeneity of patterns, some exhibiting rupture and loss of continuity of their myofilaments; c) lesser concentration of atrial granules in the perinuclear area; d) abundant granular interstitial tissue and collagen separating the myofibrils.
