ABSTRACT

Background: Young coconut water (YCW) has been used by individuals to boast immunity and that of the experimental animals. In this study an attempt was made to investigate the protective effect of YCW against the Carbon tetrachloride (CCl4) induced renal toxicity in rats. Methods: A total of 20 male adult wistar rats which were not previously subjected to any experiment were divided into four groups. Each group has five rats. Group 1 (Normal control) received basal diet, olive oil and water. Group 2 (Positive control) received basal diet, olive oil and YCW (100ml/kg). Group 3 (Negative control) received basal diet, water and CCl4 diluted with water and olive oil. Group 4 (Experimental group) received basal diet and YCW (100ml/kg) and then intoxicated with CCl4 diluted with water and olive oil. After day 7, the rats were sacrificed and their kidneys were collected and processed histologically following standard protocols. Results: Group 1 (Normal control) displayed normal histocyto-archetature of the kidney. Group 2 (Positive control) revealed hyperplasia with mild inflammatory response. Group 3 (Negative control) showed hypercellularity, mild cystic spaces, necrosis, and loose glomerular membrane indicative of high inflammatory response. Group 4 (Experimental group) revealed moderate cellular activities in line with moderate inflammatory response. Conclusion: The administration of YCW on the rat before intoxication with CCl4 suppresses the deleterious effect of CCl4 on the experimental group.

ABSTRACT

Background: Statue determination has remained a basic requirement in determining human identity and ethnicity. Usually in situations when whole anatomical structures are unavailable, forensic expert would be expected to rely on smaller structures such as the phalanges, patella ribs and other fragmentary bones. Aim: The present study evaluates toe anthropometry and its usability as predictors of the stature of the Hausa ethnic group in Nigeria. Methods: Six hundred and sixty four (664) subjects comprising of equal percentage of adult males and females were included in the study group. Toe lengths of both feet (coded as big toe or first toe [1T] to the fifth toes [5T]) were measured using a digital Vernier calliper with accuracy of 0.01mm while stature was taken using a stadiometer with accuracy of 0.1m. SPSS (IBM®) t-test was to evaluate gender difference in the measured dimensions; while SPSS and XLSTAT (2015) Automatic & Generalized Linear Modelling were used to determine the predictability of stature from the toe lengths. The significance level was set at 95% as P≤0.05 was considered significant. Results: The automatic (multiple) regression analysis showed that the males displayed significantly higher mean values than the females for all measured parameters (P<0.001). The general population regression formulae were derived and only three (3) variables (R2T, R5T and L3T) significant contributors to the models for stature prediction for the general Gp (R2=0.385, F[3, 660]=137.68, P<0.001) and female F (R2=0.137, F[3, 328]=17.367, P<0.001) population, while only the L.1T could predict male M stature (R2=0.139, F[1, 330] = 54.489, P<0.001). Single regression gender-specific formulae were derived for the measurements that provided significant R2 values. Conclusion: This study suggested that estimation of a stature of Hausa ethnic group could be made possible by using specific toe measurements. However, lengths of toe may not be so reliable in the estimation of stature, but could be used for sex discrimination in forensic investigation.

ABSTRACT

Background: Most medical schools are facing a shortage of cadavers. The general attitude and propensity is to procure more cadavers for the Institute. In their efforts to procure bodies for dissection most anatomists ignore measures which ensure their own safety. Methods: In order to assess the attitudes of the anatomists towards the donated body and its management a structured questionnaire was framed in light of the literature. Results: The trends and results indicate that a lot needs to be done to inculcate ‘safe practices’ and develop a ‘seasoned etiquette’ and ‘mindset’ towards handling of bodies received in anatomy departments. Conclusion: Standard precautions should be taken during every moment of contact with cadaver. The donated bodies must immediately be categorized on receipt and bodies unsuitable for embalming must be refused by the institution. Hepatitis B vaccination is recommended for all personnel likely to come into contact with dead bodies. Formaldehyde levels must not exceed .1ppm for closed spaces.

ABSTRACT

Background: Stature is a significant anthropometric determinant of the physical identity of an individual. Aim: This study was carried out to estimate stature of Nigerian Annang indigenes of Akwa Ibom State from hand and foot dimensions. Methods: Two hundred (200) adults Annang indigenes (100 male and female each) were randomly selected for this study. Hand and foot dimensions were obtained by direct linear measurements using a 150mm digital vernier caliper (with accuracy of 0.01mm); while stature was determined by stadiometric measurement of the height (to the nearest 0.1m). Measurements obtained include; second (2D), fourth digit (4D) and right foot length (RFL). All measurement were converted to centimeters (cm). SPSS (IBM® version 20, Armonk, New York, USA) t-test was to evaluate gender difference in the measured dimensions; while Pearson’s correlation and Generalized Linear Modeling were used to derive Regression equation for estimation of stature from the measured dimensions. The significance level was set at 95% as P≤0.05 was considered significant. Results: The t-test showed that males displayed significantly higher mean values than the females for all measured parameters (P<0.001). Single regression sex specific regression formulae were derived and the result showed that better prediction (r) values were obtained for females F (2D=0.428, 4D=0.430, RFL=0.587; P<0.01) population when compared to males M (2D=0.319, 4D=0.231, RFL=0.456; P<0.05). Conclusion: This study suggests the existence of sexual difference in hand and foot dimension and also the possibility of accurately estimating stature from the right foot length, right second and fourth digit.

ABSTRACT

Background: In the present study, we conduct an immunohistochemical analysis to evaluate the expression of matrix metalloproteinase-9 (MMP-9) in the epiligament (EL) after grade III injury of the medial collateral ligament (MCL) in an experimental model of a rat knee. Methods: Twelve 8-month old male Wistar rats were used in this study. Three animals were used as controls, while the remaining nine underwent grade III injury of the MCL. The MMP-9 immunoreactivity was evaluated on the 8th, 16th and 30th day after injury. Results: We observed an intensive expression of the enzyme in all periods after injury in contrast with the control group. We also discovered that the main source of matrix metalloproteinase-9 was localized in the epiligament tissue. Immunoreactivity was highest and homogeneously distributed on the 8th day and gradually diminished, concentrating on the EL-ligament border and the perivascular zones on the 30th day. Conclusion: We present the first immunohistochemical study of the expression and distribution of the enzyme MMP-9 in the EL of the MCL and track the changes in enzyme activity on the 8th, 16th and 30th day after damage.

ABSTRACT

Ligamentous structures connecting the middle ear and temporomandibular ligament (TMJ) are called as Otomandibular ligaments (OML). Most of the anatomists believed that OML has two parts: malleomandibular ligament (MML) and Discomallear ligament (DML). Both of these ligaments pass through the bony fissure which runs from TMJ to the tympanic cavity, called as Petrotympanic fissure (PTF). Anatomical connection between TMJ and middle ear persists mainly due to continuation of common Meckel’s structure through petro tympanic fissure (PTF). Embryological origin of the MML and DML is debatable but basically, they originates from the first arch. Though they do not play important role in primary movement of TMJ, joint dislocation, anterior disc displacement and hypermobility could happen due to stretching of the DML. MML provides the mechanical support to the head of malleus and forms a movable unit, which acts as suspensory structure for the ossicular chain. Therefore, structural alteration in the MML may plays an important role in affecting middle ear function. The disruption of MML during chronic infection or surgical release of malleus head fixation may affects middle ear sound transmission and results in conductive hearing loss. Shortening of DML by laser coagulation which permits its tightening has been suggested for the treatment of the anterior displacement of the disc. This shortening technique reduces the articular movement range, due to which it was also indicated in the treatment of recurrent temporomandibular dislocations.

ABSTRACT

There are a number of variations of the superficial veins of the head and neck reported so far. Some are commonly found and some are present rarely. These are influencing the performance of surgeons operating in the head and neck region, clinicians as well as radiologists. Material and Methods-The present variation was noticed during routine dissection of head and neck of 48year old male adult cadaver in the Department of Anatomy. Sri Guru Ram Das Institute of Medical Sciences and Research Vallah (Punjab). A rare variation of the drainage of the external jugular vein directly into the internal jugular vein on the right side was noted. The formation of the right external jugular vein was found normal. The veins on the left side were normal. The sites for long term central venous catheterization are the external jugular vein, internal jugular vein or subclavian vein. The present rare variation will alert clinicians and surgeons performing neck, vascular or reconstructive surgery about unexpected variations of the external jugular vein in the hope of preventing inadvertent injury.

ABSTRACT

Aberrant origin of ulnar artery that potentially changes its normal anatomical relationship is considerable rare. But when present, it must never be overlooked before carrying invasive procedures on the anteromedial aspect of the arm and forearm by the clinician. This would avoid unprecedented iatrogenic loss of part or entire distal part of the upper limb due to loss of arterial blood supply. While doing the normal dissection of the left upper limb on the 35 year old female cadaver, medical students saw a strangely and superficially placed ulnar artery that arose from the brachial artery way up within the upper part of the middle 3rd of the arm. This superficial ulnar artery coursed within the deep brachial and antebrachial fascia, making it superficial to all flexor muscles of the flexor compartment of the forearm. It only resumes its normal course at the wrist joint distally. The brachial artery coursed normally and bifurcated at the cubital fossa to give radial artery laterally and common interosseous artery medially. On the other hand, the right upper limb had normal arterial patterning.

ABSTRACT

Variations of the arteries of the upper limb are an often encountered phenomenon and have been widely described in case reports and studies over the years. The superficial palmar arch (SPA) is the main source of blood supply to the palm and digits. The classical SPA is formed by an anastomosis between the superficial branches of the radial and ulnar artery, although a number of other variations have been described. Herein, we present a peculiar formation of the SPA between the superficial branch of the ulnar artery and a communicating branch from the princeps pollicis artery. We also noted an unusual origin of the radialis indicis artery from the SPA. According to the classifications of SPA variations, the observed SPA was type II or a dominant ulnar subtype of the non-arch type. The knowledge of arterial variations in the hand is important for the successful conduction of surgical and diagnostic manipulations in the hand and is therefore of interest to anatomists and clinicians.
