Objective: The aim of this research was to investigate the effect of intake of palm wine on body weight, testis weight and microarchitecture of the testis in adult Wistar rats. Materials and Methods: Ten mature male rats weighing between 101 g and 180 g were assigned into two groups of A and B, consisting of five animals each that all had access to rat chow and water ad libitum. Fresh undiluted palm wine gotten as sap (juice) from oil palm trees was collected from a local palm wine tapper at every three days interval and often conserved in a refrigerator after every use before being replaced with a fresh collection on the 4th day. While group A served as control, group B animals were orally administered with 10ml/kg body weight per day of the palm wine for twenty-one days. The G&G(R) Electronic Scale (JJ1000 Capacity) was the instrument used for the assessment of the weight parameters. The analysis of variance was the statistical tool used to determine the weight differences between the two groups and P < 0.05 was taken as the statistically significant value; with the data presented as Mean ± SEM. Results: The outcome of the research on weight parameters showed non significant changes as the means for the initial and final body weights in group A were 108 g and 136 g ± 0.28 while those in group B were 138 g and 165 g ± 0.29 respectively. The testis mean weight of group A animals was 3.3 g ± 0.05 while that of group B was 3.8 g ± 0.07. Following routine histological processing, the micro-anatomic studies of testicular tissue samples from group B revealed focal disordered arrangement of sperm–producing cells. Conclusion: The findings therefore show that regular intake of fermented palm sap popularly known as palm wine may not significantly affect body weight nor testis weight, but can gradually distort testicular tissue architecture with abnormally structured cells.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"54 1","pages":"12 - 17"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78736851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: To study the morphological variations of fissures and lobes in the human cadaveric lungs. Materials and Methods: One hundred specimens of formalin-fixed adult lungs of unknown gender were studied and the following parameters were measured bilaterally: (a) presence or absence of complete or incomplete fissure, (b) presence of accessory fissure, and (c) length of fissures. The observations and measurements were recorded, compiled, and tabulated and the result was compared with the other studies. Results: Length of oblique fissure was 29.36 ± 5.61cm with range of 17.9 - 42.0 cm on the right side and 26.81 ± 8.18 cm with range of 10.8–38.9 cm on the left side. Length of horizontal fissure was 10.2 ± 8.4 cm with range of 6.1–12.8 cm on the right side. Oblique fissure was complete in 84.0% cases on the right side and was in 82.0% cases on the right side. It was incomplete or absent in 16% (R) and 18% (L) cases. Horizontal fissure was complete in 74% and incomplete or absent in 26% of cases. Accessory fissure was found in a total of eight lung specimens. Conclusions: The knowledge of anatomy of fissures of the lung provides information on lobar anatomy with variations. The present study result and its comparison with other researches confirmed that lobar architecture is not constant. It emphasizes its usefulness in the diagnostic and surgical field.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"1 1","pages":"7 - 11"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89732473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Twenty-six Rattus norvegicus male rats aged three months were used. The rats were randomly assigned into baseline (2), experimental (16) and control (8) groups. Unilateral eyelid closure was performed on the experimental animals by suture tarsorrhaphy. At experiment days 5, 10, 15 and 20, four rats from the experimental group and two rats from the control group were euthanized, their eyeballs harvested, and routine processing was done for paraffin embedding, sectioning and Masson’s trichrome staining. The photomicrographs were taken using a digital photomicroscope. Results: In the closed eyes, there was a time-dependent reduction in the stratification of the corneal epithelium with subsequent disintegration, and an increase in distribution of stromal keratocytes while the corneal endothelial cells showed slight enlargement from squamous shape. The contralateral and control eyes did not exhibit any significant changes through the experimental period. Conclusion: Monocular eyelid closure causes structural changes in the corneal epithelium, stroma and endothelium of the tarsorrhaphy eye. Therefore, tarsorrhaphy should not be prolonged due to risk of corneal diseases and diminution of vision as a result of the structural changes.

This study was aimed at determining factors that influence pregnant women's requests for ultrasound sex identification of fetuses in Enugu, South-East Nigeria. Materials and Methods: A descriptive cross-sectional study of pregnant women attending antenatal clinic at University of Nigeria Teaching Hospital, Enugu, was done. A structured questionnaire was used to obtain information on the factors influencing their willingness to know the sex of their unborn children. Results: A total of 416 responses were obtained. Nearly 40.4% of the respondents were interested in knowing the sex of their children. Almost 56.3% preferred to have a male child, 8.7% preferred to have a female child while 25.5% of the respondents were indifferent. Those who had preference for a particular sex were more interested in requesting for prenatal sex determination than those who did not (54.2% vs. 24.0%). Those who had family pressure for a particular sex were more interested than those who were not pressured (65.9% vs. 33.1%). Other factors that influenced their desire to request for the prenatal sex of their children were preference for a male child, desire for more children dependent on the sex of the index fetus, and desire for more children (irrespective of the sex).

Beneficial effects of moderate exposure to infrared lamp have been itemized to include enhancement of blood circulation, relief from muscular pain, and wound healing acceleration with scarce information on biological effects when it is overexposed. Therefore, there is a need to investigate the possibility of its overexposure on biological system, especially blood parameters. Aim: This study was aimed to determine the biological effects of overexposure to radiation from infrared lamp on blood parameters. Materials and Methods: Infrared lamp of 100 W acts as a source of the IR. Twenty male healthy Wistar rats of the age range between 10 and 12 weeks and weigh between 100 and 250 g were studied. All the animals studied also acts as a control group with their blood samples taken and recorded as initial counting values. The animals were later divided into three groups: A, B, and C according to their hours of exposure according to their weight. Animals in Groups A, B, and C were exposed to IR for 1, 3, and 5 h, respectively. Blood samples of each animal in the group were taken 24, 48, and 96 h after exposure. The total number of erythrocytes, leukocytes, lymphocyte, and neutrophils were counted and compared with the initial samples. Results: The results revealed that packed cell volume, white blood cell, and lymphocytes of all the exposed animals averagely decreased by 17.4%, 17.5%, and 11.3%, respectively, whereas neutrophil increased by 19.0% after exposure to infrared.

Efforts are being made to uncover other indicators of hypertension than the traditional and crude one popularly used, i.e. BMI. Obesity and overweight are common causes of most cardiovascular diseases. Aim: The study examined which anthropometric variable better predicts hypertension among adults in Enugu State of Nigeria. Materials and Methods: Sample of the present cross-sectional study included 540 (288 females and 258 males) adults aged 28-74 years old. Five anthropometric variables (weight, height, chest, waist, and hip circumferences) and blood pressure were measured. Data were collected by means of questionnaires from patients attending Korean Enugu State University Teaching Hospital. Subject is classified as being hypertensive if systolic blood pressure (SBP) >140 mmHg and/or diastolic blood pressure (DBP) >90 mmHg. Results: The overall prevalence rate of hypertension was found to be 26.30% while 24.4% and 28% were recorded for males and females respectively. The prevalence was not significantly associated with gender (χ2 = 0.899, P = 0.343). Hypertension was found to be related to age, weight, chest, waist, and hip circumferences, and waist-hip ratio (P < 0.05) but not height (P > 0.05). Waist circumference with the largest area under the ROC curve was the best predictor of hypertension for all sample population, males and females respectively 0.67, 0.68 and 0.66.

Normal values of foot arch parameters have been studied in various populations. However, studies in Nigerian population are very limited and therefore require attention. Objective: The objectives of this study were to establish the normal values of foot arch parameters in adult Hausa population of Nigeria, to find the effect of gender on these parameters and to make comparison with previous studies in other populations. Materials and Methods: A total of 59 consented subjects (44 males, 15 females) that have no history of lower extremity deformity were recruited. Lateral radiograph of the right foot of each participant was taken in a bilateral standing position. For the medial longitudinal arch, navicular height (NH), first cuneiform height (FCH), calcaneal inclination angle (CIA), and calcaneal- first metatarsal angle (C1MA) were measured. Cuboid height (CH) and calcaneal-fifth metatarsal angle (C5MA) were measured for the lateral longitudinal arch. Measurements for angles and heights were performed using a universal plastic goniometer and a plastic ruler, respectively. Results: The mean (standard deviation [SD]) value of the NH was found to be 2.89 (0.54) cm, FCH 2.08 (0.44) cm, CIA 16.57° (3.30°), and C1MA 140.05° (5.63°). The mean (SD) of CH and C5MA was found to be 1.19 (0.31) cm and 160.96° (4.69°), respectively. There was no significant mean difference in those parameters between males and females.
