Reliability of the bicaudate parameter in the revealing of the enlarged lateral Ventricles in schizophrenia patients.

Introduction: In schizophrenia patients the lateral ventricle enlargement has mostly been reported in relationship with smaller cortical and/or subcortical brain volumes; and it has been observed that ventricular system growth may be a consequence of the smaller caudate nucleus volume. Bicaudate parameters have been used in the Alzheimer dementia and Huntington's chorea diagnosing in order to evaluate brain changes and the enlargement of the lateral ventricles.

Subjects And Methods: This study has been carried out on 140 patients out of which 70 patients (30 men and 40 women) who met the ICD 10 criteria for schizophrenia and 70 healthy controls (30 men and 40 women) matched on sex and age with the studied group.

Morphometric parameters as risk factors for anterior cruciate ligament injuries - a MRI case-control study.

Background/aim: The anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee, representing 50% of all knee injuries. The aim of this study was todeter mine the differences in the morphometry of knee injury patients with an intact and a ruptured anterior cruciate ligament.

Methods: The study included 33 matched pairs of patients divided into two groups: the study group with the diagnosis of anterior cruciate ligament rupture, and the control group with the diagnosis of patellofemoral pain but no anterior cruciate ligament lesion.

[The role of the posterior tibial slope on rupture of the anterior cruciate ligament].

Background/aim: Posterior tibial slope is one of the most citated factors wich cause rupture of the anterior cruciate ligament (ACL). The aim of this study was to determine the association of a greather posterior tibial slope on the lateral condyle, that is a lesser posterior tibial slope on the medial condyle, with ACL rupture.

Methods: The patients were divided into two groups.

The third branch of the main trunk of the left coronary artery in Cercopithecus aethiops sabaeus. Is the nonhuman primate model appropriate?

The aim of this study was to investigate the morphometry of branching patterns of the main trunk of the left coronary artery (MT of LCA) in nonhuman primates, and comment on the current nomenclature. The biometric study was performed using stereomicroscopic dissection of hearts of healthy and fertile nonhuman primates (Cercopithecus aethiops sabaeus) of both sexes. Our results reveal that the MT of LCA terminates in a bifurcation into the anterior interventricular branch (AIB) and the circumflex branch (CB) (74.

Expression of Bcl-2 and Bax proteins in thyroid glands of rats in experimental thyroiditis.

In the recent years, iodine was associated to the development of apoptosis in thyroid diseases. The aim of the present study is to determine the expression of pro-apoptotic and anti-apoptotic proteins, Bax and Bcl-2, in a Wistar rat experimental model of thyroiditis induced by administration of different doses of potassium iodide. Immunohistochemical staining was done with chromogen diaminobenzidine on avidin-biotin peroxidase using the Animal Research Kit (ARK), stained with antibodies to Bcl-2 and Bax proteins.

[Relations of aqueduct with some structures of mesencephalon].

Introduction: Aqueductus mesencephali is the biggest part of the ventricular system and that is why it is the most common place of intraventricular obstruction of cerebrospinal fluid. This study was done in order to study topographic characteristics of aqueduct more thoroughly.

Materials And Methods: Transversal sections of mesencephalon were made in three levels.

[Morphological and laminar distribution of cholecystokinin-immunoreactive neurons in cortex of human inferior parietal lobe and their clinical significance].

Introduction: Cholecystocinine is a neuropeptide whose function in the cortex has not yet been clarified, although its relation with some psychic disorders has been noticed. Previous studies have not provided detailed data about types, or arrangement of neurons that contain those neuropeptide in the cortex of human inferior parietal lobe. The aim of this study was to examine precisely the morphology and typography of neurons containing cholecytocinine in the human cortex of inferior parietal lobule.

[Characteristics of galanin and vasoactive intestinal peptide immunoreactivity in the rat amygdala complex].

Introduction: Morphological features and morphometric parameters of galanin (GAL) and vasoactive intestinal peptide (VIP) immunoreactive neurons and neuronal fibres were studied in all nuclei of adult male rat amygdala.

Material And Methods: After perfusion and fixation, rat brains were immunohistochemically stained with antibodies against GAL and VIP and then visualized by avidin-biotin-peroxidase complex.

Results And Discussion: The greatest number of galanin-immunoreactive neurons were identified in the medial part of the central nucleus and in the dorsal part of the medial nucleus.

A histological study of cerebral aqueduct.

Cerebral (sylvian) aqueduct is a narrow channel in the mesencephalon. It lies between the tectum and the tegmentum of the mesencephalon and is surrounded by the periaqueductal gray matter. The aim of this study was to determine the shape of the aqueduct of sylvius and the structure of its walls in a series of transverse histological sections.

[The role of enteroclysis and roentgen anatomy of jejunumand ileum in Crohn's disease].

Introduction: The aims of this research were: 1) to establish the value of enteroclysis in detection of morphological changes of jejunum and ileum in cases with suspected Crohn's disease and 2) to establish types of morphological changes of jejunum and ileum in patients with Crohn's disease.

Material And Methods: The study compared two groups of people who voluntarely accepted to be examined: a control group and a study group. The control group included 11 healthy people, without gastrointestinal symptom.

Third coronary artery in monkey heart.

Investigations were carried out on 55 monkey (Cercopithecus aethiops, Macaca fascicularis) hearts by stereomicroscopic dissection and measurements. Latex-injected specimens and corrosion casts showed that, as in humans, the hearts were usually (in 98.2% of the cases) supplied by two coronary arteries (CAs)--the left (LCA) and the right coronary artery (RCA), and occasionally (in 1.
