The possible effects of the electromagnetic fields (EMF) generated by mobile phones on reproductive functions have been discussed in recent years. The aim of this study was to evaluate the effects of EMF emitted from mobile phones on the rat testis morphology and histopathology using stereological techniques. We also investigated cortisol, testosterone, FSH and LH levels. A total of thirty-two (n = 32) male Wistar albino rats were used in this study. Animals were randomly divided into four groups as control (C, n = 8), sham (Sh, n = 8), mobile phone speech (Sp, n = 8) and mobile phone standby (ST by). Morphometric measurements were made with the help of a computer-assisted stereological analysis system. The testis weight and volume were significantly lower in the EMF exposed groups. The mean volume fraction of interstitial tissue was higher, but the volume fraction of tubular tissue was lower in the EMF-exposed groups. The mean tubular and germinal tissue volume, seminiferous tubule diameter and germinal epithelium height were also lower in EMF exposed groups. The cortisol levels in the EMF-exposed groups were significantly higher. In conclusion, the EMF created by mobile phones caused morphologic and histological changes by the affecting germinal epithelium tissue negatively.
Objective This study aims to determine the topographic localization of the stylomastoid foramen (SF) and its morphometric relationship with the surrounding bony landmarks.
Design A descriptive anatomical study.
Setting Anatomy Laboratory of the Faculty of Medicine.
Participants Measurements were performed on 53 dry temporal bones.
Main Outcome Measures On the inferior and lateral aspects of photographic images, lines and angles were defined. The most lateral end of the SF (SF1) and the transverse medial–lateral line that passes through the upper end of the anterior border of mastoid process (line 1) were used as reference points for topographic evaluation. The upper end of the anterior border of mastoid process (A) and the tip of mastoid process (B) were considered in defining angles. The dates about SF were evaluated using the ImageJ 1.46r software and digital caliper.
Results SF1 was classified into three different types based on its topographical localization, stated as Type 1, Type 2, and Type 3. In Type 1, SF1 was located anterior to line 1 (54.7%). SF1 was located posterior to line 1 in Type 2 (34.0%). SF1 was located just over line 1 in Type 3 (11.3%). We also detected angular variations between these types in the inferior and lateral aspects.
Conclusions The recommended angles of application are 30 degrees on the horizontal plane and 55 degrees on the sagittal plane for Type 1 when point B is considered. A needle length below 10 mm is more suitable to minimize the potential complications of the nerve block.
“Teşrih-ül Ebdan ve Tercümânı Kıbale-i Feylesûfan” is the first handwritten anatomy textbook with illustrations written in Turkish in 17th century by Şemseddîn-i İtâḳî. “Teşrih” has different meanings such as anatomy, skeleton, and cutting a corpse into pieces [1]. “Teşrih-ül Ebdan ve Tercümânı Kıbale-i Feylesûfan ” means dissection of the body and scholars’ birth knowledge [2]. Since this is the first handwritten textbook in Turkish, it has great importance in the development of medicine in Ottoman Empire. This book was written while Grand Vizier Recep Pasha was in power, and it was dedicated to the Sultan of that period, Murat the IVth [3, 4]. It is thought that the book was written in 163
Massage is the manipulation of the body tissues by using techniques, such as rubbing, kneading, pressing, and rolling to sustain a state of health and wellness. Massage is one of the oldest and most natural healing applications in human history. Avicenna (980 -1037) gained a very important position in the medical world with his most important work, the Canon of Medicine, known as the holy book of medicine in the Western world. Different types of massage were defined in the book. These were hard friction that braces the body, soft friction that relaxes the body, repeated friction that reduces the amount of fat in the body, moderately hard friction that improves the body, rough friction that leads the blood to the surface rapidly, gentle friction that increases blood flow in the application area, preparatory friction that prepares the body before exercise, and restorative friction that is applied after exercise which alleviates exhaustion. It may be seen that Avicenna, whose work shows influence of Greek and Roman physicians, was heavily influenced by Hippocrates and Galen. It is seen that the massage techniques and effect mechanisms defined by Avicenna about a thousand years ago have contributed a lot to the developments in massage through the historical process.
