    ABSTRACT: Introduction: The foramen magnum is a unique and complex neuroanatomical structure. This is an important landmark of the skull base for neurosurgical procedures. The aim of this study is to analyze the morphometry pertaining to variations of the shapes and sizes of foramen magnum separately for males and females of Indian population along with comparing antero-posterior and transverse diameters available in literature and to bring out associated clinical implications. Methods: Thirty-five dry skulls (13 females and 22 males) have been examined for morphometric variations of foramen magnum. The surface area of foramen magnum was calculated manually using graphical method. The importance of morphometry and clinical significance of foramen magnum has been established by available literature. Results: Mean antero-posterior diameter and transverse diameter of foramen magnum are 33.8±02.5mm and 28.2±02.6mm, respectively. The minimum, maximum and mean areas of foramen magnum in assorted skulls are 434mm2, 902mm2 and 648.5±112.2mm2, respectively. Foramen magnum index in assorted skulls vary from 1 to 1.45. Discussion: The dimensions of foramen magnum, separately for males and females in the Indian population, have been analyzed for the first time. This analysis will be of paramount importance for clinicians in surgical procedures around this region.

    ABSTRACT: The objective of this review is to summarize the knowledge about the anatomy of the lumbar intervertebral foramen (IVF) as an anatomic entity. The intervertebral or neural foramen is an orifice located between any two adjacent vertebrae that allows communication between the spinal canal and the extraspinal region. We describe the osseous structure of the lumbar foramen, the adjacent ligaments and its components including the arteries and veins passing through or neighboring it, and the spinal nerves and roots. Although lumbar spine structures are familiar to spinal surgeons and many procedures are performed in the area of the lumbar IVF, yet surprisingly little is known about the precise anatomy of the foramen and the triangular working zone of it.

    ABSTRACT: Introduction: Imidacloprid was the first insecticide of the wide group of neonicotinoids introduced to the market. Neonicotinoids were developed in the late 1980s and in early 1990s as a response to the widespread insect's resistance to older insecticides, such as organophosphates, pyrethroids, and carbamates, and their health and environmental issues. Imidacloprid is a widely applied pesticide due to its higher affinity for insect nicotinic acetylcholine receptors, and it acts on nervous system. Methods: The present study was carried out on 300 fertile eggs of white leghorn chicken obtained from government poultry farm after taking permission from animal ethical committee. Chicken eggs exposed to imidacloprid with doses of 5. μg, 10. μg, and 20. μg in a volume of 5. μl, 10. μl, and 20. μl respectively and control same as test group. The embryos were terminated on 21st day, eggshells broken with a scalpel, and embryos removed. Dissection of chick head was done for collection of brain. Histological and immunohistochemical processing was done for cerebellum of chick embryos using neurofilament polypeptide (NFP) and glial fibrillary acidic protein (GFAP) markers and observed under microscope and using photographs. Results: The results show that experimental group had comparatively more cases of histological changes, GFAP immunoreactive in glial cells, and NFP immunoreactive in neuropil and neurons. Patchy clustering and degenerative changes in neurons with focal pyknosis and karyolysis in comparison to controls were seen. Discussion: Imidacloprid exposure increases the risks of histological changes. Comparatively higher doses proved more toxic and also caused many histological and immunohistochemical changes in cerebellum of chick embryos.

    ABSTRACT: Introduction: The wing of ilium bone has a very complex shape and therefore requires a series of measurements. For complete morphometry, we suggest 22 parameters and statistical approach, which allows to generate 12 parameters based on regression analysis of already measured 10 parameters from anteroposterior (AP) radiographic projection. Methods: The study was conducted on a sample of 32 male CT scans of the right hip bone as input data. We imported the CT scans, stored in DICOM format, in Computer Aided Design program and identified 15 anatomical points and 22 parameters (linear distances between the points) on each wing, measured the values of these parameters, and processed them with tools of descriptive statistic and regression analysis in order to generate 12 nonlinear regression models. Results: The results of our study are presented in the form of 12 simple one-parameter regression equations, where p values for regression coefficients in equations are less then 0.01 and value of variance R 2 is up to 0.543. Discussion: Obtained nonlinear regression models (3 square, 6 exponential, and 3 logarithmic) are the result of the complex shape of the wing of ilium. According to p-values for coefficients in the regression equations, we can consider the results as statistically significant. This approach is time-efficient because the measuring is conducted only on AP radiographic projection. The findings of this study are useful for predicting subject-specific morphometry.

    ABSTRACT: Introduction: The aim of our research was to quantify the synaptic density in the parahippocampal region of the brain with densitometric measurements of synaptophysin immunoreactivity in cases of different ages. Methods: The study was performed on post mortem obtained right parahippocampal region (PR) samples of 14 cadavers (10 males, 4 females) whose ages ranged from 35 to 80 years. The samples were classified into three age groups (I: 30-49; II: 50-69; III: 70 and older). The tissue was immunohistochemically processed and stained with an anti-human synaptophysin antibody. The densitometric analysis included measurement of the mean and median optical density (OD) of the PR gray and white matter (WM) digital images. This was performed with ImageJ. Results: The histological analysis showed that the neuropil of the PR's layers showed two types of synaptophysin positive reactions. The first type was characterized by the presence of a granular pattern of synaptophysin immunoreactivity, and this was less intense in the second type. The synaptophysin immunopositivity of the PR gray matter neuropil decreased with age, especially in its superficial layers. The results of the densitometric analysis confirmed the significant decrease of the gray matter mean and median OD during aging. A One Way ANOVA showed that only the mean and median optical densities of the third age group were significantly lower than the values for the first age group. Discussion: The synaptic density decreases with age in the PR, but this decrease is significant only in cases older than 70 years.

    ABSTRACT: Peroneus longus (PL) in man assumes special significance as it helps in maintaining the foot in plantigrade position and simultaneously maintains the arched character of foot. During evolution, insertion of PL has migrated from the lateral border of foot to reach its medial border, through the deep part of sole, getting purchase on the contiguous parts of lateral surface of the medial cuneiform and base of 1st metatarsal in its lower part. Hence, it was expected that some interesting variations in the insertion of PL may be found.

    ABSTRACT: Background: Limited data are available from India that describe the normative volume and size of ventricular system. We add our experience with normative values of Evan's index to measure the ventricular size on CT scan in apparently healthy individuals. Methods: A total of 326 patients were included in the study, in whom brain CT scan was performed for various indications and it was apparently normal. Evan's index ratio was obtained by measuring maximum frontal horn width to the maximum transverse diameter of the inner table in the same section. The data entry and statistical analysis were done using StatsDirect® version-3. Data were expressed as mean, standard deviation, actual numbers, and percentages. Results: We divided the Evan's index into two categories, <0.3 and >0.3, which indicates ventriculomegaly to find out % of abnormality. The mean Evan's index in these patients was 0.25. ±. 0.02. There was no trend in Evan's index with increasing age. It was appreciated that there was not much variation in calculation of Evan's index from CT scan. It was found that Evan's index could be calculated fairly accurately by multiple observers, which could be appreciated in the form of very small standard deviations. Conclusion: In summary, the normative values of Evan's index in a group of persons were similar to as described in literature. Less than 5% of patients were having ventriculomegaly but there were no clinical symptoms related to ventriculomegaly.

    ABSTRACT: Introduction: Estimation of sex is an important initial step for personal identification of unknown skeleton remains in forensic investigation. The aim of the present study was to evaluate the applicability of the sternum for sex estimation of adult skeletal remains by measuring the sternum of Thai individuals. Methods: A study of 281 adult Thai dry sterna with known sex (192 males and 89 females) was carried out for sexing by using measurements. Discriminant function analysis was used. Results: The results showed that all parameters included in this study were significantly sexually dimorphic except sternal width index. By using discriminant function analysis, it was observed that the best parameter was the combined length of manubrium and mesosternum yielded cross-validated sex allocation accuracy rate 85.8% (82.4% for male and 95.7% for female), followed by sternal area with classification accuracy rate 82.9% (79.2% for males and 91.2% for females) and the length of mesosternum with classification accuracy rate 81.1% (78.8% for males and 88% for females). A stepwise discriminant function, which included 5 linear measurements from both manubrium and mesosternum yielded highest classification accuracy rate of 86.4%. Discussion: The results of the present study proved that the sternum is a reliable element for sex determination in Thai population and it may be a useful tool in forensic investigations.

    ABSTRACT: The study of tracheo-bronchial branching pattern and formation of bronchopulmonary segments is of great importance in understanding lung anatomy and physiology. While teaching this subject to first year medical students, teachers often take help of atlases and digital images. Preparation of a cast of tracheo-bronchial airways would be of great help to make the students understand the three-dimensional branching and relation between various segments of lungs and thus to better understand pulmonary anatomy.
