Carcinosarcoma of the lung is an admixture of cardinomatous and sarcomatous lesion and accounts for 0.3% of all pulmonary neoplasm. Clinicopathological features are often related to anatomical location : central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic tests had a low yield in detection carcinosarcoma. Metastasis to regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is less than one year.Two cases of carcinosarcoma patients are reported here - one case is composed of undifferent cell carcinoma and spindle cell sarcoma in the male of 72 year old and the other case squamous cell carcinoma and spindle cell sarcoma in the male of 65 year old.

Carotid body tumor is rare tumor in the neck. Among the pathologic conditions affecting paraganglionic tissue. the carotid body is most frequently involved. There are controversies in terms of natural history. biological behaviors, technique of excision, risks of the operation. Carotid angiography is the most valuable diagnostic aid and important for the planning of therapy. Definite treatment of carotid body tumor is surgical excision. Considerable degree of caution and vascular surgical armamentation are required because of its anatomical location and profuse vascularity. Surgical removal of this kind of paraganglioma must be predicated upon several factors such as tumor character. location. symptom, vascularity, and surgeon's ability.

The abducens nerve paresis generally can aid in the presumptive diagnosis of abducens schwannoma along with the typical radiological features of schwannomas. The authors present a case of a 76-year-old male patient with a abducens schwannoma without abducens nerve paresis. Peroperatively, abducens nerve located in the cerebellopontine cistern had normal in contour and diameter, despite the mass originated from this nerve. We hypothesize that anatomic location of abducens nerve may affect the vector of tumor growth to prevent destruction of its origin, the abducens nerve.

Background : The location of acupoints on rat, which may differ from that of human body due to anatomical structure, is defined variously among researchers, which may cause the problem of low repeatability and objectivity. Design : The measurement of hind limb consist of measuring the distance between knee joint and tibia tubercle in order to set the knee joint as common criteria. Based on it, the three mostly referred location of ST36 were represented with the knee joint as a datum point and compared. The electroacupuncture stimulation was administrated after the abdominal pain was induced by acetic acid. And the analgesic activity of each ST36 acupoint was evaluated by measuring the number of writhing reflex, in order to observe the differences of treatment effect in accordance with the location of ST36 acupoints. Results : The result of measurement confirmed the differences in the acupoint location of ST36 among researchers. The writhing reflex test using the acetic acid-induced abdominal pain stimulated with electroacupuncture of 100Hz showed that there were statistically significant differences in the analgesic effect between control group and three ST36 groups (P<0.05). However there were no differences observed among three mostly referred location of ST36 acupoints (P>0.05). Conclusions : We recommend "the point located 6.5 mm below the knee joint at the anterior tibial muscle" as a standard ST36 acupoint location qualified by the WHO Standard Acupuncture Point Locations in 2008.

Introduction: This study examined the anatomical morphology of the medial surface of the posterior mandible using 3-dimensional cone-beam computed tomography (CT) images to reduce the number of complications related to dental implant placement. Materials and Methods: Fifty patients were enrolled in this study with an average age (${\pm}$standard deviation) of 44.28 (${\pm}13.05$). On the coronal views cone-beam CT of the first molars, the distance between the top of the canal and alveolar crest vertical distance (VD), the distance between the upper-most point of the canal and the point perpendicular to the lingual cortical margin of the mandible lingual distance (LD), the location of the starting point of VD for reducing from the vertical reference line (VD point), and the inclination of the mandibular medial surface (lingual inclination) were measured, and a statistical evaluation was performed using SPSS for Windows version 15.0. Results: The mean VD0 was $16.91{\pm}2.47\;mm$ and VDx decreased with increasing x value. The mean LD was $5.27{\pm}1.36\;mm$. The VD began to decrease at the mean location of $6.12{\pm}0.96\;mm$ from the vertical reference line. The mean lingual inclination was $1.52{\pm}0.72^{\circ}$. Conclusion: These results will assist in the accurate placement of dental implants and the reduction of complications, particularly in the case of preoperative implant planning using only 2-dimensional imaging methods.

This study was performed to define the anatomical position of the mandibular canal and the findings during the sagittal split ramus osteotomy of the mandible. The mandibles of 20 adult Korean were used. The dimension of mandibular canal from the mandibular foramen to the 1st molar was measured at 4 specific coronal-sectional location by CT scan. The results were as follows ; 1. The distance from the mandibular canal to the medial aspect of the buccal cortical plate was greatest($4.5{\pm}1.1mm$) at 2nd molar area and was not significantly greater than at any other section. 2. Buccal cortex was thickest($3.8{\pm}0.9mm$) at 2nd molar and thinnest ($2.5{\pm}0.3mm$) mandibular foramen um 3. The distance from the mandibular canal to the medial aspect of the lingual cortical plate was not significant at any sections. 4. The distance from the mandible canal to the inferior border of mandible was greatest at the mandibular foramen($20.7{\pm}3.9mm$). The canal was located more closely to the inferior border at 1st, 2nd molar area 5. The diameter of the mandibular canal was between $2.5{\pm}0.3mm$ and $2.8{\pm}0.6mm$. 6. The total mandibular thickness was greatest($21.1{\pm}2.6mm$) at 2nd molar area and narrowest($17.2{\pm}3.2mm$) at mandibular foramen area.

Background: The purpose of this study was to identify the location of the antilingula, lingula, and mandibular foramen in Korean cadavers and to promote safe and accurate surgery without damage to the inferior alveolar neurovascular bundle (IANB) when performing a vertical ramus osteotomy (VRO). Methods: This study was conducted on the dried mandibles of 20 adult cadavers. Digital calipers were used to measure the distances from the anatomical reference points (antilingula, lingula, and mandibular foramen). Result: The antilingula was located at the anterior 44% and superior 31% in the ramus. The lingula was located at the anterior 55% and superior 30% in the ramus. The mandibular foramen was located at the anterior 58% and superior 46% in the ramus. Regarding the positional relationship with the antilingula, the lingula was located 0.54 mm superior and 4.19 mm posterior, and the mandibular foramen was located 6.95 mm inferior and 4.98 mm posterior. The results suggested that in order to prevent damage to the IANB, osteotomy should be performed in the posterior region of ramus at least 29% of the total horizontal length of the ramus. Conclusion: Using only the antilingula as a reference point is not guaranteed to IANB injury. However, it is still important as a helpful reference point for the surgeon in the surgical field.

Objectives and Methods : The present study was to investigate the change of acupuncture point location of gallbladder meridian in head by way of reviewing classical literatures. Result and Conclusions : 1. The locations of acupuncture points closed-by anatomical marks such as GB1, GB2, GB3, GB11, GB12, GB19, GB20 are clear and accurate. 2. The expression of acupuncture points' locations of GB4, GB5, GB6, GB8 and GB10 are obscure in classical literature, but their locations became clear and objective in recent literatures. 3. The locations of GB9 and GB13 are open to dispute but WHO standard acupuncture point seems to be resonable. 4. In classical literature, the length from the midpoint of the anterior hairline to the midpoint of the posterior hairline is 12 B-cun, and the length from the midpoint of the anterior hairline to the GB19 is 5 cun, 5.5 cun or 6.5 cun. We presume that the length from GB15 to GB19 might have been measured by F-cun.
