  • Septoplasty/septorhinoplasty is a common ear, nose and throat procedure offered for those patients with deviated septum who are suffering from nasal obstruction and functional or cosmetic problems. Although it is a basic and simple procedure, it could lead to catastrophic complications including major skull base injuries which result in cerebrospinal fluid (CSF) leaks. We describe two different cases of traumatic CSF leaks following septoplasty/septorhinoplasty at two different sites. The first patient suffered a CSF leak following septoplasty and presented to Alexandria University Hospital. The leak was still active at presentation and identified as coming from a defect in the roof of the sphenoid sinus and was repaired surgically. The second patient presented 4 days after her cosmetic septorhinoplasty with a CSF leak and significant pneumocephalus. She was managed conservatively. Understanding the anatomical variations of the paranasal sinuses and implementing proper surgical techniques are crucial in preventing intracranial complications when performing either septoplasty or septorhinoplasty. A good quality computed tomography of the nose and paranasal sinuses is a valuable investigation to avoid major complications especially CSF leaks following either procedure.

  • The knee joint is composed of 3 skeletons that is the femoral bone, the tibial bone, and the patella bone. The tibiofemoral pint and patellofemoral pint act with the meniscus, so these function that is maintain the stabilities by the surrounding soft tissue is complex. The protection mechanism(muscle tension) of the surrounding muscles for the joint disease(Arthritis) limits consistently the motion of the pint to decrease the internal pressure of the joint, and these muscle tension acts with abnormal function for the surrounding tissue and the joint, sometimes the contracture is developed, if the joint with disease is not recovery or treated within early time. So we worked out efficient orthopedic local taping for the patient who is complained of the knee pint pain using the literature investigation about the anatomical structure and the biomechanics of the knee pint for the muscle and the pint problem esp, the rotation of the tibia, the dislocation of the patella, and the motion of the meniscus that is developed due to tension of surrounding muscles of the knee pint. And application of the pint mobilization, the stretching, and the muscle strengthening exercise for the pint will become successful treatment for the joint disease.

  • Study Design: Observational study. Purpose: To assess the correlational accuracy between the traditional anatomic landmarks of the neck and their corresponding vertebral levels in Southern Chinese patients. Overview of Literature: Recent studies have demonstrated discrepancies between traditional anatomic landmarks of the neck and their corresponding cervical vertebra. Methods: The center of the body of the hyoid bone, the upper limit of the lamina of the thyroid cartilage, and the lower limit of the cricoid cartilage were selected as representative surface landmarks for this investigation. The corresponding vertebral levels in 78 patients were assessed using computed tomography. Results: In both male and female patients, almost none of the anatomical landmarks demonstrated greater than 50% correlation with any vertebral level. The most commonly corresponding vertebra of the hyoid bone, the lamina of the thyroid cartilage, and the cricoid cartilage were the C4 (47.5%), C5 (35.9%), and C7 (42.3%), respectively, which were all different from the classic descriptions in textbooks. The vertebral levels corresponding with the thyroid and cricoid cartilage were significantly different between genders. Conclusions: The surface landmarks of the neck were not accurate enough to be used as the sole determinant of vertebral levels or incision sites. Intra-operative fluoroscopy is necessary to accurately locate each of the cervical vertebral levels.

  • Objective: Spermatogenesis is a complex process that is regulated by a number of genes, some of which are involved in folate-dependent 1-carbon metabolism. Methionine synthase (encoded by MTR) is a key enzyme participating in this pathway. This study aimed to investigate the relationship of the MTR 2756A > G polymorphism with idiopathic male fertility in the Iranian population. Methods: The participants of this study included 100 men with idiopathic infertility and 100 healthy men as the control group. Genotyping of MTR 2756A > G was performed using the polymerase chain reaction and restriction fragment length polymorphism technique. The obtained data were analyzed using SPSS ver. 20.0 with a level of confidence of p< 0.05. Results: The frequencies of the A and G alleles at this locus were 77% and 23% in infertile patients and 84% and 16% in the control group, respectively. The frequencies of the GG, GA, and AA genotypes were 5%, 36%, and 59% in the infertile patients versus 3%, 27%, and 70% in the control group, respectively. No significant difference was observed in any genetic models. Conclusion: In general, the findings of this study suggest that the MTR 2756A > G single-nucleotide polymorphism is not a predisposing factor for idiopathic infertility in men.

  • In arctic zone of West Siberia, native people's bodies were sometimes mummified inside the medieval graves. In 2013 to 2017, we conducted the excavations of medieval graves at Zeleny Yar cemetery in Yamalo-Nenets Autonomous Okrug. Among the burials, current report deals with the mummy grave #79. During the investigation, bronze plate and strips, woven or fur clothing, leather strap, beads, bronze bracelets, and iron knife etc. were collected. Anatomical and radiological research showed that the mummy was found intact with hair, skin, and skeletons, but the preservation status of soft tissue differed greatly depending on the area. The brain and eyes were well preserved, but the chest and abdominal organs almost disappeared. The arms were preserved to some extent, but only the bones remained in the legs. The West Siberian mummy could be a great resource for anthropologists to reveal the biological aspects of arctic indigenous people.

  • Recently, the consumption of mistletoe[Viscum album var. coloratum(Kom.) Ohwi] is increasing because of its good medical effectiveness with the increased concern on the natural medicines and foods. The result obtained from the investigation on the stem tissues of the mistletoe and the oriental chestnut oak, a host plant species, are as follows. Haustorium from the seeds of the mistletoe after their sticking to the branches of the host plant penetrates into the bark where it forms the endophyte system through the active cell division. The endophyte grown in the cambium of the host plant makes the stems and leaves as the outer tissues in a certain time. Even through lignification of the host wood in the branches the oriental chestnut oak was not progressive, its tylosis coas developed partially assembly due to the formation of the endophyte. The stems of the mistletoe consisted of vascular tracheid, selereid, and ray and axial parenchyma, classified as a hardwood without vessels. The vascular tracheids seemed to take a role instead of the vessels in the mistletoe plant from the result that the pits of the vessels in the host branches are linked to the vessel-form tracheid in the mistletoe stems. The constituent ratio of the sclereid cells in the mistletoe stems increased with aging. Furthermore their ratio of the parenchyma cells was higher, which contained the more cell content, compared with the cells of the general woody plant species.

  • Purpose : To evaluate the morphologic measurement and microvasculature of the normal human meniscus in Korean and to compare the difference of microvasculature according to the age and anatomical location. Materials and methods : Menisci of 21 cadavers divided into 3 groups according to the age. Each meniscus was divided into 10 parts of which the width and area of microvasculature were measured. Results : The average width of the medial and lateral menisci were $10.49{\pm}02.92mm$ and $10.55{\pm}2.05mm$, respectively. The average area of the microvasculature measured $20.29{\pm}8.44\%$ in the medial meniscus and $18.99{\pm}7.03\%$ in the lateral meniscus. The microvasculature of the medial meniscus was most abundant in the anterior horn and least abundant in the posterior horn (p<0.05). The lateral meniscus showed the most vessels in the posterior horn (p<0.05). The microvasculature of popliteal hiatus was not avascular but hypovascular. The area of microvasculature decreased with increasing age in all parts of the medial meniscus and body and posterior horn of the lateral meniscus (p<0.05). Conclusion : Differences in the anatomical distribution of the vessels were noted of both the medial and lateral menisci. The area of microvasculature generally decreased proportionally with increasing age in both medial and lateral meniscus.

  • This study was carried out the anatomical and histological investigation of the olfactory organ on a land-locked and an amphidromous Plecoglossus altivelis in Deokam-ri, Shinpyeong-myeon, Imsil-gun, Jeollabuk-do and Daeduk-ri, Gojeon-myeon, Hadong-gun, Gyeongsangnam-do, August, 2021, Korea. The external morphology of the two types of P. altivelis was indistinguishable, featuring a pair of the elliptical anterior nostrils, the semicircular posterior nostrils, and the nasal flaps on the snout. The olfactory organ consisted of 20 to 22 olfactory lamellae forming a rosette structure in the nasal chamber. The secondary folds appeared on the lamellae. The histological results were also uniform. The sensory epithelium was a continuous type, consisting of olfactory receptor neurons, supporting cells, basal cells, cilia, and an unidentified cell. The non-sensory epithelium found only in the terminal part of lamellae, consist of stratified epithelial cells, basal cells, and mucous cells. For the olfactory organ between a land-lock type and an amphidromous type, no difference was observed in external and histological structure between amphidromous and land-locked type. However, it is considered that P. altivelis has higher olfactory sensitivity than other anadromous fish due to more number of olfactory lamellae and the presence of the secondary folds.

  • To observe the respiratory system in relation to the air-breathing organ in Iksookimia longicorpa, micro-anatomical investigation was performed on the epidermis and on intestinal tract fragments. The epidermis was distinguished by two types of skin glands, a small mucous cell and a large club cell. The mucous cell was acid sulfomucins (some sialomucins), but the club cell did not give any histochemical tests for mucosubstances. The presence of a well defined lymphatic system with small lymphocytes was established in the stratum germinativum layer of the epidermis. A large number of blood capillaries run very close to each other just below the basement membrane. The straight intestinal tract is divided into an intestine and rectum, which consisted of a mucosa (epithelial layer), lamina propria-submucosa, muscularis, and serosa. The intestine and rectum have shorter mucosal folds and a thinner wall. The majority of the epithelial mucous cells contain acid sulfomucines. Based on the above results, I. longicorpa adapts to poor dissolved oxygen conditions by using an additional respiratory system using air through the epidermis, not the intestines.
