Ultrastructural studies made in this area are mostly animal based. We aimed to evaluate wall changes and three-dimensional organization of the elastic lamellae with aging in humans. Material and Methods: Common carotid arteries were obtained from 17 human cadavers which were grouped as G1 (n = 6), 30–39 years; G2 (n = 5), 40–49 years; and G3 (n = 6), >50 years of age. Samples were evaluated under light and scanning electron microscopes. Results: Examination of G1 revealed intimal thickening and foamy cell infiltration. G2 and G3 had plaques bulging into the lumen and interlamellar space was widened. The lamellae were more straight. There was a positive correlation between intimal thickness and age. Elastic fiber content decreased with aging. Scanning electron microscopic analysis confirmed the findings. G1 and G2 had a smooth surfaced internal elastic lamina with uniform fenestrations whereas G3 contained numerous irregular fenestrae. Discussion and Conclusion: With this study, we showed some other wall structure changes beside plaque formation by aging. Which layer is affected the most was not clear at previous clinical studies because using ultrasonography (USG) cannot address the layer. Microscopic evaluation of this study revealed that when a wall thickening is detected by USG, it is due to intimal thickening. The specific vessel layer structural changes are important for proper treatment.","PeriodicalId":50010,"journal":{"name":"Journal of the Anatomical Society of India","volume":"71 1","pages":"261 - 265"},"PeriodicalIF":0.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46013154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chronic consumption of AL may lead to its accumulation in tissues causing AL toxicity. The study aims to investigate the toxic effect of AlCl3 on hippocampus region of rat brain by qualitative and quantitative analysis of neurons. Material and Methods: Adult male albino Wistar rats were divided into three groups with six rats in each group. Group 1 was the control, Group 2 rats received 100 mg/kg b. w, and Group 3 received 300 mg/kg b. w of AlCl3 orally for 30 days. The neuronal count was done at the CA1, CA2, CA3, and CA4 regions of hippocampus by staining with cresyl violet stain. Neuronal damage in the AlCl3 groups was compared with the control group. Results: A significant damage was observed in all the regions of hippocampus both in Groups 2 and 3 compared to the control group (P < 0.00001). Further higher dose of AL caused marked neuronal damage in CA1 (P < 0.03) and CA3 (P < 0.05) regions compared to the lower dose of AL. The neurons in the CA3 and CA1 regions were most vulnerable to AL toxicity and the CA2 region of the hippocampus had a maximum number of viable neurons indicative of resistance to AL toxicosis. Discussion and Conclusion: Consumption of higher dose of AL even for a short term could have variable degrees of deleterious effects on different regions of the rat brain. This study sets a background for an in-depth exploration on toxicology of AL compounds on human participants which could be of public health importance.","PeriodicalId":50010,"journal":{"name":"Journal of the Anatomical Society of India","volume":"71 1","pages":"307 - 310"},"PeriodicalIF":0.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46233232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The otologic surgeons need to have a thorough knowledge of anatomical details and variations to provide better operative results and for surgical maneuvers. The present study aimed to analyze the morphological variation and morphometry of the ear ossicles and compare the parameters with those reported in previous studies. Material and Methods: The study was conducted on 28 mallei, 26 incus, and 20 stapes obtained from the cadavers allotted for dissection. Measurements were documented, and the morphological variations were analyzed. Results: The average of the parameters showed that the malleus was 7.59 mm in total length with an angle of 130°; the manubrium was 4.65 mm, the total length of the head and neck was 5.01 mm, and the average weight was 21.50 mg. The incus had a total length and width of 6.37 and 4.89 mm, respectively; a maximal distance of 5.97 mm between the tips with an angle of 101° and weighed an average of 23.81 mg. The stapes had a total length of 3.36 mm, with the stapedial base being 2.83 mm in length and 1.41 mm in width, and weighed an average of 3.16 mg.

Hence, a thorough anatomical knowledge of the human ossicular chain is required for clinicians for surgical maneuvers and for designing prosthetics to replace the adult middle ear ossicles.","PeriodicalId":50010,"journal":{"name":"Journal of the Anatomical Society of India","volume":"71 1","pages":"266 - 271"},"PeriodicalIF":0.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47124073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CT evaluations were made with a 128-slice multislice CT scanner in two projections, axial and coronal. Slice thickness was taken as 1 mm for volumetric analysis.

Results: The volume of MACs and isolated unilateral CB did not change with age; however, the volumes of male participants were larger than that of women.

Aim: The study aims to determine the prevalence of variations of the CoW in patients from Serbia via magnetic resonance angiography (MRA). Material and Methods: The study was conducted as a retrospective study at the Center for Imaging Diagnostics, Oncology Institute of Vojvodina. Magnetic resonance imaging was analyzed in 665 patients of both sexes (471 females and 194 males), who underwent MRA during 2018 and 2019. Results: Complete CoW was found in 48.42% of cases, mostly in females (68.01%). Partially complete CoW and incomplete CoW were encountered in 38.05% and 13.55% of patients, mostly in females (73.52% and 73.33%). Anterior circulation variations were seen in 27.41% of cases, higher in females (63.83%), most commonly A1 anterior cerebral artery hypoplasia (9.32%). Posterior circulation variations were seen in 46.36% of cases, higher in females (79.25%), most commonly posterior communicating (PCom) artery hypoplasia (25.56%). Combined variations were seen in 26.24% of patients, with higher prevalence in females (73.33%). The prevalence of variations of posterior circulation between male and female patients was statistically significant (P = 0.007) and was higher in females.
