Background and Objectives : High volume, low pressure (HVLP) cuffed tubes have been substituted for low volume, high pressure (LVHP) cuffed tubes in order to reduce complications created by the cuffed endotracheal tubes contact with the tracheal wall. Several physidans, however, prefer to use the LVHP cuff for habitual or economic reasons. Even so, careless cuff Inflation of the HVLP cuff could also induce complications. The purposes of this study were to see whether there are any differences between the usual intracuff pressure (UICP) and the Optimum intracuff pressure (OICP), to compare the OICP of three groups, and to study the correlation between the OICP and the peak inspiratory pressure (PIP) of three kinds of endotracheal tubes under mechanical Ventilation. Methods : 82 adult patients, upon admission of the ICU, were divided into 3 groups with different cuffed tube types according to the following: Portex Profile group (n=66), HVLP cuffed tube; Portex Regular group (n=11), LVHP cuffed tube; Rusch Red group (n=5), LVHP cuffed tube. We used the Portex cuff pressure manometer for Portex Profile group, the Hewlett-Packard pressure transducer for Portex Regular, and Rusch Red group to measure the intracuff pressure (ICP). The OICP was measured with the minimal leak technique (MLT). Intracuff pressure difference (ICPD) was calculated by subtracting OICP from UICP. Results : UICP and OICP of Portex Profile group were 33.12±22.25 ㎝H₂O, 22.02±12.5㎝H₂O, Portex Regular group, 70.09±30.88 ㎝H₂O, 69.45±30.41 ㎝H₂O and Rusch Red group, 378.40±38.60 ㎝H₂O, 337.60±74.45 ㎝H₂O. Significant difference was shown among the groups (p < 0.05). The significant difference of the PIP was not seen among the groups. Significant correlation between OICP and PIP (regression = 0.463, p < 0.01) was demonstrated only in Portex Profile group. ICPD of three groups were as high as 84 ㎝H₂O to as low as -56 ㎝H₂O. About 40% of the patients showed the allowable range. Conclusions : This study suggests that routine check-ups of ICP are needed when the patients are admitted to the ICU. The OICP of the HVLP cuffed tube is 1/3 -1/15 of the LVHP cuffed tube. Therefore, the routine use of the HVLP tube is highiy recommended. The OICP shows positive correlation with the PIP. This suggests to make every effort to reduce the PIP.

의약품의 약효를 안전하게 나타내기 위해서는 정확한 용량의 복용이 중오하다. 정해진 용법 ·용량에 따라 투여를 하더라도 1회 복용단위당 항량이 균일하지 않으면 복용자의 의지에' 관계없이 과량 혹은 유효량에 디치지 못하는 양을 복용하게 되므로 복용단위당 유효성분의 균질성은 매우 중요하다. 이에 국내 시판 의약품 중 경구용 성형제제를 대상으로 중랸과 항랑의 균질성 평가 및 상관성에 대한 기초적 연굴를 통하여 함량군일성시험의 규긱 설정에 관한 기준을 마련하고자 하였다. 국내 시판 중인 총 560롯트의 경구용 성형제제에 대하여 주성분의 수 함량 등에 따라 븐류하고 함량시험, 중량편차, 함량균일성시험을 실새하여 중량편차와 함량균일성의 상관계수를 구하였으며, 상관성분석을 통하여 각 분류한 군에서 상관성 있는 것으로 나타난 롯트의 비을을 살펴보았다. 주성분 함유량 2% 미만, 혹은 2 mg 미만인 제제에서는 함량균일성으로의 관리가 필요한 것으로 나타났으며, 제형에 따라서는 당의정에서 상패적으로 상관성 있는 롯트의 수가 적게 나타나 함량균일성으로의 관리가 필요한 것으로 나타났다

Intrathoracic goiter consist of two types, namely, the primary intrathoracic goiter and secondary intrathoracic goiter. Primary intrathoracic goiters are very rare. Fifteen to fifty percent of these patients are asymptomatic. Symptoms, when present, are usually the result of tracheal or esophageal compression. Standard chest roentgenograms are often diagnostic but computed tomographic or radioactive iodine scans may be helpful. In symptomatic patients or those in whom explorations are undertaken for diagnostic purpose or exclude carcinoma, surgical removal is indicated. We report here on a case that was completely removed with using the thoracoscopic assist technique. The postoperative courses were uneventful.

Mesenteric cyst is a rare intraabodominal mass which is composed of most fibrous tissue with focal lining by flattened cells, cholestrol clefts and foam cells but lack of smooth musscle components and elements of the Iymphatic system. And, this entity is frequently misdiagnosed preoperatively as a cystic Iymphangioma. Therefore, histologic and ultrastructural evidence suggest that they are pathologically distinct. It must be distinguished from other intraabdominal and retroperitoneal cyst because outcome of surgical treatment is different. We report a case of mesenteric cyst arising in mesentery of ascending colon in a 46 year old male who had developed as a presenting symptom of periumbilical pain for 2 days before admission, with review of literatures.
