Effects of Ambroxol, S-carboxymethylcysteine, Dextromethorphan and Noscapine on Mucin Release from Airway Goblet Cells

In the present study, we investigated whether ambroxol, S-carboxymethyl-L-cysteine, dextromethorphan and noscapine affect mucin release from airway goblet cells. Confluent primary hamster tracheal surface epithelial cells were metabolically radiolabeled and chased for 30 min in the presence of varying concentrations of the above agents to assess the effects on 3H-mucin release. Noscapine stimulated mucin release during 30 min of treatment period in a dose-dependent manner. However, ambroxol, S-carboxymethyl-L-cysteine and dextromethorphan showed no significant effect on mucin release during 30 min of treatment period. We conclude that noscapine can affect mucin release by acting on airway mucin-secreting cells.

Postinfarction Left Ventricular Free Wall Rupture / 대한흉부외과학회지

Left ventricular free wall rupture following acute myocardial infarction (AMI) is the second most common cause of death and has been reported to be responsible for 4 to 24% of all infarction deaths. The rupture occurs anywhere from a few hours to several days after AMI. The common findings of ventricular rupture are persistent chest pain bradycardia and shock. This may be often mistaken for the ruptured dissection of the ascending aorta. The different points from dissection are 1) persistent chest pain 2)persistent ST segment elevation and 3) only intramural hematoma in ascending aorta. We have sucessfully managed two patients with postinfarction myocardial rupture. Surgical management consisted of infarctectomy repairi of the ventricular rupture and coronay artery bypass grafting. We conclude that successful surgical management of ventricular free wall rupture should require prompt diagnosis and emergency operation.

Dynamic Study of the Larynx with Spiral CT in the Tumors of the Pyriform Sinus and Supraglottis

PURPOSE: To evaluate the CT findings of tumor in the pyriform sinus, and to assess by functional study of thelarynx the extent the extent to which its characteristic findings differ from those of supraglottic tumor. MATERIALS AND METHODS: CT scans of 14 patients with tumor in the pyriform sinus were reviewed and compared withthose of 17 patients with supraglottic tumor. In all cases, spiral CT scanning linvolved both quiet breathing andmodified breath holding; we evaluated the images and analysed the primary site of tumors and the displacement ofair in the pyriform sinus. Extra and intralaryngeal extension of the tumors was also assessed. RESULTS: In tumorsin the pyriform sinus, CT findings were thickening of more than two walls in 14, the displacement of air in 9,extralaryngeal extension in 13, extension to the post-cricoid space in 11, invasion of the pre-epiglottic space in13, and widening of the cricothyroid space in 8 patients. In supraglottic tumors, CT findings were thickening ofthe medial wall in 17, extralaryngeal extension in 1, extension to the post-cricoid space in 1, invasion of theipsilateral paralaryngeal space in 17, and of the contralateral paralaryngeal space in 6, invasion of thepre-epiglottic space in 11, and widening of the cricothyroid space in 9 patienhts. In this type of tumor thedisplacement of air was not seen. CONCLUSION: The characteristic CT findings of tumor in the pyriform sinus werethickening of more than two walls of the pyriform sinus and the anterior or medial displacement of air. To assessthe site at which a tumor originates, spiral CT scanning is needed, together with functional study.

Dynamic Study of the Larynx with Spiral CT

PURPOSE: It is essential to know the functional and morphologic changes of the larynx in the evaluation of laryngeal lesions. Conventional CT which has relatively long examination time is not suitable for this aim. The purposes of this study are to evaluate the capability of spiral CT in the dynamic study of the larynx and to know whether this new technique can replace conventional laryngography or not. MATERIALS AND METHODS: Five healthy volunteers and 20 patients with laryngeal lesions underwent spiral dynamic CT scans with 3-dimensional reconstruction of the mucosal surface. A series of spiral CT scans were done while the volunteers performed various laryngeal positions to obtain the functional and morphologic information. The maneuvers used were:quite breathing, "E" phonation, Valsalva maneuver, modified Valsalva maneuver, and a new method of our own, "modified breath holding" technique. The patients were scanned when in quite breathing. Additioal scans were obtained by using the "modified breath holding" technique. RESULTS: The dynamic study with spiral CT could provide high resolutional images which nicely depicted the mobility of vocal cords and the mucosal changes of the laryngeal cavity in both healthy volunteer and patient groups. In patient group, the new "modified breath holding" technique was easier and more reproducible than other maneuvers. CONCLUSION: Spiral CT allows a dynamic study of the larynx and can be a new alternative of laryngography.

False Positive CT Findings of Parametrial Invasion of Cervical Carcinoma

PURPOSE: To evaluate the causative factors of the false positive CT findings of parametrial invasions of cervial cancer. MATERIALS AND METHODS: we analysed 17 parametria of 14 patients with the diseases staged over lib on CT, but confirmed to be under stage Ila on pathology. The CT findings were retrospectively reviewed, and compared with pathologic findings. RESULTS: The causes of false postive diagnosis of parametrial invasions on CT were prominent cardinal ligaments (n=12), vaginal fornix(n=3), and prominent uterine vessels(n=2). CONCLUSION: Familiarity with these CT finding may be helpful in avoiding false positive diagnosis of parametrial invasion in patients with uterine cervical carcinoma.

Tc DMSA scintigraphic findings in renal tuberculosis

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.

Complication of the Kuntscher Nailing in Fracture of the Femoral Shaft / 대한정형외과학회잡지

Several techniques are now avallable for the treatment of fractuers of the shaft of the femur. We must be aware of the advantages, disadvantages and Ilmitation of each if we are to select the proper treatment for each patient. During last decades treatment had been varied markedly from time to time and from place to place. Before Word War II, most fractures of the femoral shaft were treated conservatively either by skeletal traction or by manipulation and immobilization in a spica cast. After medullary fixation was Introduced during that war, it became popular, and until 1960 many surgeons considered it as the treatment of choice for most of these fractures. If the case is properly selected the medullary fixation is almost perfect, provlded no complications develop; convalescence can be shortened and resldual disability can be decreased. We had experienced 14 complications among the 78 cases of Kuntscher nailing from may, 1974, to May, 1980. The results are as follows: 1. We operated 78 cases with Kuntscher nail among the 121 femoral shaft fractures. 2. 14 (17.95%) complications developed among the 78 cases of the Kuntscher nailing. 3. Technical errors were incarcerated nailing with thick nail, too long nail and thin nailing. 4. Early postoperative complications within a year were infection, bendlng, bursitis, angulation and rotation. 5. Late complications after one year were proximal or distal migration and refracture.

The Expreience of Treatment of Trochanteric Fracture of the Femur / 대한정형외과학회잡지

It has been emphasized that the treatment of choice for the trochantric fracture of the femur is open reduction and rigid internal fixation to reduce complications by early ambulation. The incidence of trochanteric fracture of the femur in the young age group has been considerably increased in recent years because of increased traffic and industrial accidents. The author treated 38 cases of trochanteric fracture of the femur in the year 1974 through 1979, at the Department of Orthopaedic Surgery, School of Medicine, Soon Chun Hyang College. The results were as follows: 1. In sex distribution, 24 out of 38 were males and 14 were females. 16 cases out of 24 male patients were in the age group 20-40 and 9 cases out of 14 female were over 60 years of age. Over all mortality was 7.9%. 2. The numbers of patients of type I and III were 11 cases in each type out of 38 trochanteric fracture. 3. 26 cases out of 38 cases were treated by open reduction and internal fixation and the others were by traction and cast. 4. The applied metal devices were 3 types: Smith-Peterson nail and Thornton or McLaughlin plate, compression hip screw, and multiple pinning. 5. Mean duration of bony union is shorter in the group of open reduction and internal fixation (13 weeks) than the group of traction and cast (15 weeks). The cause of difference is that the 6 out of 9 cases of type IV and V were included in conservative group. 6. The incidece of the complications such as coxa vara, slipping screw, long nail and traction palsy occurred higher in the group fixed with Smith-Peterson nail and plate than the group fixed with compression hip screw.

Suitable Weight-Height Type Indixes for the Evaluation of Nutritional Status / 예방의학회지

This study was conducted to find out the most suitable weight-height index out of the weight/height(p)-type indices that could be used for the evaluation of nutritional status in an epidemiological survey and for the screening of the obesity. The subjects were chosen randomly, 2,182 males and 719 females from college students and office workers in Seoul districts. The 'best' power-type weight-height index for Korean men and women of all ages from 16 to 59 was found to be weight-height(1.54) for males and weight-height(1.42) for females. Weight-height(2)(Kaup index), however, was the best suited weight-height index for each age group of both sexes except that relative weight (weight-height) was considered to be desirable to apply for males of teen-aged and of over fifties and for females of over forties of age. Normal ranges of Kaup index values for males and females of each age group were presented in tables 5 and 6. These findings suggest that Korean are generally leaner than other ethnic groups of the same sex and age.

Clinieal Study of 72 Cases of Supracondylar Fracture of the Humerus / 대한정형외과학회잡지

Supracondylar fracture is the most frequent injury of the elbow and frequently accompanies complications in children. Seventy two cases of supracondylar fractures have been treated and managed at Department of Orthopaedic Surgery, Catholic Medical College during the period from Jan. 1969 to Dec. 1972. The evaluation of fracture was done according to the classification of Holmberg and Hoyer. Among 72 cases of the supracondylar fracture, the most common type is 29 cases of Grade 2: (40.2%). Most cases were treated conservatively, and various method of treatment were adopted according to the condition of fracture. Residual angular deformities after successful manipulative reductiion can be accurately evaluated roentgenographically by the Baumanns method. Good results were obtained in 62.6%, fair results in 33.3%, and poor results in 4.1%. The incidence of cubitus varus deformity is 37.5%. There were no instance of ischemic contracture and no permanent neurological deficit in fracture cases.
