Age-Related Changes in the Urinary Bladder of the Female Albino Rats

Disturbances of the urinary bladder functions are common in the elderly people particularly women. So, it was the aim of the present work to detect the age-associated changes in the urinary bladder that might play a role in the bladder dysfunctions. Twenty albino rats were used in the present work. They were divided into two equal groups, each consisted of ten rats. The first...

INNERVATION OF THE PRONATOR TERES MUSCLE

The pronator quadratus is the principal muscle responsible for pronation of forearm, helped by the pronator teres. To study the innervation of the pronator teres, eighteen forearms from a formol fixed corpses were dissected and the relationship of the median nerve to the pronator teres was examined. The elbow articular line was used as reference point. In all cases the most...

EVALUATION OF THE IMPLANTATION IN PINEALECTOMIZED AND/OR SUBMITTED TO THE CONSTANT ILLUMINATION RATS

In this paper we evaluated the morphologic and quantitative aspects of the implantations sites in uteruses of female pinealectomized and/or submitted to the constant illumination rats. The experimental groups were: I - normal female rats maintained in a clear/dark cycle of 12/12 hours, for two months, mated and euthanasiated in the 6th day of pregnancy (control); II - female sham...

MORPHOMETRIC STUDY OF MENISC OF THE KNEE JOINT

We analyzed the meniscus morphometrics aspects of the knee joint as such: extern circunference tickness, the breadth, the area and distance between anterior and posterior horns, the tibial plateau correspondent area, meniscus area/tibial plateau report, check the Wrisberg's ligament length. There were analyzed 44 meniscus of the 22 knees adults men corpses. The tickness and...

Presencia de Receptores de Estrógenos y de Progesterona en el Endometrio de Ovejas Prepúberes: Estudio Inmunocitoquímico

The endometrial esteroid receptors play an essential paper in the reproductive physiology being them decisive on the morophuncional state of the genital tract and especially of the endometrium in which the embryo will be implanted. We studied the presence of estrogens and progesterone receptors in the endometrium of Rommey Marsh prepubertal sheep (n=3) samples of uterine wall...

Rotator cuff Disease: Aspects and Implications

The objetive this study was analyze the characteristics of the rotator cuff disease carrying and its implications by the lesion evolutional stage. 112 patients with initial diagnosis of rotator cuff disease were interviewed, most of them women, average age of 51 years, right side more injured, with evidence to be the most damaged (p=0,00) and with a lot incapacity to move the...

Sistematización de las Cadenas Nodales Linfáticas de la Pelvis Femenina

The investigation studies on the sentinel node in cancers of the feminine genital apparatus return indispensable systematizing the pelvic lymphatic nodes as well as the use of a unique nomenclature. The importance of the sentinel node in the cancer of uterine cervix is more and more evident. From the anatomical and surgical point of view we must be precise at the time of...

Attempts at Applying Cloning to the Conservation of Species in Danger of Extinction

The somatic cloning by transfer of the nuclei of differentiated adult cells to previously enucleated oocytes is a promising technique for the production of embryos of high genetic value. The better mastering of somatic cloning gives us the possibility to produce embryos from endangered species. The huemul is an Andean native deer, that has been declared an endangered species, it...

Anomalous Branching Pattern of Lateral Cord of Brachial Plexus

During routine dissection, an unusual formation of median nerve was detected in the right upper limb of a 55 year old male cadaver. The median nerve had an additional contribution from lateral cord. The two branches of the lateral cord designated as upper and the lower branches were observed at different levels. The upper branch was in close contact with the third part of the...

Extraoral Ligature of Lingual Artery: Anatomic and Topographic Study

The lingual artery constitutes one of the branches of the external carotid artery, which is responsible for the vascularization of the tongue and neighbour regions. The hemorrhage caused by a lesion of the lingual artery can occur during a dental procedure (surgical accidents by the use of an instrument or rotating disc), by trauma, biopsy and dental implant. In some cases is...

Triple Right Renal Vein: An Uncommon Variation

We report an unilateral three renal veins the right kidney in an elderly male cadaver. They were three calibrous veins having independent courses up to the inferior vena cava. No other vascular anomalies were noted in this specimen. This anatomical curiosity should be kept in mind by clinicians and academics that may manipulate this anatomical area

Topografía y Biometría del Sistema Venoso Coronario y de sus tributarias

The coronary sinus (SC) is the main end of the cardiac veins, being the principal vein of the heart, draining all its blood, except that driven by the anterior cardiac veins and the minimum cardiac veins. Its location is well-defined in the posterior portion of the coronary sulcus between left atrium and ventricle. Its direct tributaries are the cardiac veins: magna (VCM), media...

Análisis Biométrico de las Arterias Comunicante Anterior y Cerebral Anterior en el Segmento Precomunicante del Círculo Arterial Cerebral

The conformation of the cerebral arterial circle has relevance in the clinical neurosurgery for the complex relate that present the arteries that originate it and its great variability. Due to the high frequency with that aneurysms are observed in the anterior communicant artery and the anterior cerebral artery in the precommunicating segment (A1), we have decided to make an...

Foscarnet Effects on the Rat Pregnancy Outcome

There are few long-term data on which to base decisions of drug management of HIV infection in pregnancy. The determination of safe medications must take into consideration the need for certain drugs and the possibility of inadvertent fetal exposure because of unplanned pregnancies. The aim of this study was to evaluate the effects of foscarnet on the entire period of rat...

Relaciones del Plexo Braquial con la Segunda Parte de la Arteria Axilar

62 axillas, 32 on the right upper limb and 30 on the left one were analyzed aiming a more detailed study of the topographic relationship between the brachial plexus' (BP) cords and the second part of the axillary artery (Aa). Once the second part of the Aa was determined (retropectoral part of the axilla) the authors observed that some of the BP's cords lost their identity during...

Cyclophosphamide Effect on the Epithelial Covering of Rats Fetuse's Tongue: A Morphometric Study

The present study has the aim to describe morphologically, morphometrically and stereologically some changes in the tongue epithelium of rat fetuses under the effect of cyclosphosphamide. This drug was used in a single 6mg/kg according to the body weight in the tenth ­ pregnancy day while the control group received equal dosage of saline solution by the same duct and in the same...

Histological Changes of the Ovary of Adult Mice Exposed Prenatally to Flunitrazepam

Flunitrazepam (FNZ) is a minor tranquillizer involving allosteric modulation of the GABA receptor complex. It is a ligand of the peripheral benzodiazepine receptor (PBR) that participates in cholesterol transport in steroidogenic organs. The purpose was to investigate whether a single oral dose of FNZ of 2.5 mg/kg of body weight (bw), administered on day 6 of gestation, alters...

Unusual Relation of the Median Nerve with the Accessory Head of the Biceps Brachii Muscle: An Original Case Report

During the laboratory dissection of the brachial region and the arm, an abnormal relation of median nerve with the accessory head of biceps brachii muscle has been observed unilaterally on the right upper limb of a male cadaver. Whereas the short and long heads have their normal origin, additional-excess third head originated from the anteromedial surface of the superior part of...
