The aim of this study was to investigate the immunohistochemical characteristics of the haemal nodes located in the abdominal and the thoracal cavity in roe deer (Capreolus capreolus). In this study, two adult male and two adult female roe deers in addition to two roe deer foetuses at the late fetal stages were used. The avidin-biotin-peroxidase technique was applied to anti-CD3, anti-CD79αcy, anti-macrophage, anti-S100 primary antibodies. Positive results were gained for all the antibodies used. Many CD3 positive T lymphocytes were seen in the lymphoid tissue areas of the fetal haemal nodes, in the germinal center of the lymph follicles of the adult haemal nodes and in their lymphatic cords...

BACKGROUND: The ultrastructural alterations related to tendinopathy have not been well described. Most studies on this subject have been conducted many years ago and focused on material from the Achilles tendon. It was demonstrated that various comorbidities can affect ultrastructural alterations in the advanced tendinopathy, however there is very little data on ultrastructural morphology in tendinopathies related to mechanical overload as in case of the long head of the biceps brachii tendon (LHBT)...

BACKGROUND: Communications between the median, ulnar and musculocutaneous nerves in the arm, forearm and hand were reported in adult cadaveric and electrophysiological studies. These communicant branches may lead conflicting clinical and electrodiagnostic outcomes. While there are many studies on adult patients or cadavers, there is poor regarding fetuses. The present study was conducted to examine the frequencies of these communications and their coexistences in human fetuses. MATERIALS AND METHODS: Anterior aspect of the forearms of 50 fetuses (29 females, 20 males, and 1 unknown) were dissected bilaterally (totally 100 sides) for this purpose...

BACKGROUND: Purkinje cells (PCs) pathology is important in cerebellar disorders like ataxia. The spatial arrangement of Purkinje cells after different treatments is not being studied extensively. Immunohistochemistry (IHC) analysis of cerebellum can give a proper tool for explaining the pathophysiology of PCs in ataxia. Here we stereologically analyzed the three-dimensional spatial arrangement of PCs in the cerebellum of rats after ataxia induction with 3-acetylpyridine (3-AP). METHODS: Ataxia was induced in Rats by intraperitoneal injection of 3-AP (65 mg/kg)...

Pygmy Acrobat has unique set of morphological, anatomical and behavioral features that make it a promising model for study of primate evolution. Among the many locomotor adaptations, it should be mark a wide range of movements such as gliding, climbing, running, arboreality. This type of behavior can result from differences in anatomy and physiology of the brain systems involved in its integration. It is well acknowledged that dopaminergic neurons are involved in motor control, motivation and cognition. Due to the fact that there are no data on morphological organisation of dopaminergic system in the midbrain of Acrobates pygmaeus, we decide to do this using immunohistochemical and quantitative methods...

BACKGROUND: Tendinopathy of the long head of the biceps brachii tendon is one of the most common, painful conditions of the anterior part of the shoulder and often coexists with rotator cuff tears. Multifactorial etiopathology of tendinopathy is poorly understood, however, several studies indicated that it is seen predominantly in areas with decreased vascularity of the tissue; the pathology is also characterized by expansive and abundant neovascular in-growth. The aim of the study was to investigate the relationship between the neovascularization of proximal part of the long head of the biceps brachii tendon and pain along the bicipital groove...

Total leukocyte count increases significantly in response to infection, trauma, inflammation, and certain diseases. Factors affecting leukocyte count in healthy adults include sex, hormonal milieu, genetic inheritance, stress level, diet, nutrition, and lifestyle (e.g. tobacco-induced inflammatory changes, chronic psychological stress, etc.). To date, numerous studies have reported that high but normal leukocyte counts at baseline predict increased cardiovascular and noncardiovascular mortality in older adults...

Variations of the forearm musculature are vastly described in the literature. The palmaris longus muscle is one of the most variable structures of the human body. It usually rises from the medial epicondyle of the humerus and inserts itself into the palmar aponeurosis. Anatomy textbooks and recent papers state that this muscle may act as a weak wrist flexor. The present work aims to report an anatomical variation where the palmaris longus muscle was abnormally hypertrophied and was completely fleshy throughout the whole forearm...
