  • Objectives : The aim of this work is the approaching of properties-flavours theory and the making of morphological standard in Artemisiae herba. Methods : The properties-flavours theory were attempted with bibliographic method and various climate-information. The external-internal morphological standards were determined by using stereoscope and butanol series. Conclusions : The following is a list the conclusion of the approaching of properties-flavours theory and how to make the standard of morphological standard in artemisiae herba. 1. The significant analysis for the artemisiae herba as the properties-flavours theory, is a follow-up survey of the effect written in the official oriental medicine book 2. The other analytic methods according to the gathering time, processing or storing system or especially nature or growth environment(altitude, temperature,. the mean moisture, and the agronomical survey) by way of the explanation of properties-flavours theory appears so many insufficiency at the many cases. 3. In the case of artemisiae herba., there are 2 cases(Artemisia capillaris $T_{HUNB}$ and A. iwayomogi $K_{ITAMURA}$) in current and recently A. aruwa L. is substituted for artemisiae herba in circulation. 4. The external and internal characteristics according to the shape of original plant or herbal states, entirely correspond to all the official oriental medicine boo 5. According to the place of productiot the difference appeals. (1) A. capillatis $T_{HUNB}$. has leaves like a fine thread, and A. iwayomogi $K_{ITAMURA}$ has big and wide leaves, and shows some reddish color, and A. aruwa L. has narrow leaves, its section lines long vertically. (2) In the internal shapes, as the A. capillatis $T_{HUNB}$. leaves', upper epidermal cell wall shows relatively straight form, its all upper- lower epidemical cell wall has a stoma, and calcium rosette crystal is relatively few. As iwayomogi $K_{ITAMURA}$, all upper- lower epidermal cell wall is wavelike concave, and hypodermics has many stoma and many calcium rosette crystal. (3) In the internal shapes of A. aruwa L. the shape of leaves' epidermal cell is irregular and has so many non-glandular hair nad glandular hair on its surface.

  • Previous studies on genetic transformation of chrysanthemum using cold regulated gene (BN115) have been conducted and the PCR and Real-Time PCR based method to determine the presence of the transferred cold regulated gene in the chrysanthemum was established. To check whether over-expression of BN115 gene in transgenic chrysanthemum will enhance their tolerance to cold stress, the transgenic chrysanthemum were grown under low temperature condition and several cold signalling including growth characteristics, stoma size and shape, SPAD value and ion leakage test were investigated. The transgenic chrysanthemum in the low temperature growth chamber grow much faster in term of the height, number and size of the leaves than those of wild-type plants and damage of transgenic plant caused by the low temperature was much less than that of wild-type plants. The stoma type and size of transgenic plant leaves grown at $5^{\circ}C$ were much similar to of wild-type plant cultured on $25^{\circ}C$ It has been found that SPAD value of transgenic plants was much higher than those of wild-type, but the EC density being lower under low temperature condition.

  • Fruit and seed morphological characteristics were investigated in 36 taxa of 20 genera of Korean Ranunculaceae. As a result, fruits were classified as the achene, berry, or follicle type. In the taxa with achene, the presence of trichomes and stoma on the surface of the fruit and a feature in which the endocarp distinctively develops into a one-layer sclereid were considered as useful characteristics. Moreover, in the taxa with follicles, the composition of the seed coat (bitegmic vs. unitegmic), the cell shape of the seed coat, the presence of trichomes, and the type of seed coat were useful for taxonomic characteristics in Korean Ranunculaceae. Based on the fruit and seed characteristics, Adonis is likely to be classified into Helleboroideae rather than Ranunculoideae, as it has bitegmic ovules. In addition, Enemion is similar to Eranthis in unitegmic ovule and the seed coat structure which has non-sclereid exotesta; therefore, it is reasonable to be placed in Helleboroideae. According to the results of this study, more in-depth research is needed regarding the taxonomic positions of Callianthemum and Actaea, which has the only berry fruit type.

  • Many etiological factors playa significant role in the development of tracheal stenosis; too high tracheostomy (Jackson, 1921), too small stoma (Greisen, 1966), the treatment with respirator using cuffed tube (Pearson et al., 1968; Lindholm, 1966; Bryce, 1972) and infection (Pearson, 1968). Although the incidence has been reduced due to development of surgical technique and antibiotics, the frequency of tracheal stenosis which produces symptoms after tracheostomy ranges from 1.5 per cent (Lindholm, 1967). In the management of the stenosis, mild cases are treated by mechanical dilatation with silicon tube or stent (Schmigelow, 1929; Montgomery, 1965) combined steroid (Birck, 1970), and in the cases of stenosis causes, these removed under the are bronchoscopy. But in severe stenosis, transverse resection with subsequent end-to-end anastomosis has been used in recent years (Pearson et al., 1968). During about 10 years, 1967 to 1977, a total of 23 patients with tracheal stenosis complicated among the 1, 514 tracheostomies have been treated in Severance Hospital. Now, we have obtained following conclusions by means of clinical analysis of 23 cases of tracheal stenosis. 1. The frequency of tracheal stenosis was 23 cases among 1, 514 cases of tracheostomy (1.5%). 2. Under the age of 5, these are 12 cases (52.2 %). 3. The sex incidence was comprised of 18 males and 5 females. 4. The duration of tracheostomy ranges from 4 days to 16 months. 5. The primary diseases requiring tracheostomy were following; central nerve system lesions 11 cases, upper air way obstruction 10 cases, extrinsic respiratory failure 2 cases. 6. Severe wound infections were only 2 cases. 7. The methods of treatment applied to tracheal stenosis were following; closed observation only 5 cases, nasotracheal intubation combined steroid 5 cases, T-tube stent combined steroid 3 cases, fenestration op. 4 cases, revision 4 cases and transverse resection and end-to-end anastomosis 2 cases.

  • Background : Stomal recurrence that occasionally follows total laryngectomy is associated with very poor prognosis regardless of treatment modality, so it is very important to identify high risk patients to prevent stomal recurrence. Objectives : We attempted to select an optimal management method to prevent stomal recurrence by analyzing risk factors in each patient who was found to have stomal recurrence following total laryngectomy. Materials and Methods : Risk factors in each of eleven patients who had stomal recurrence out of 159 patients who underwent total laryngectomy in the last ten years were analyzed retrospectively. Data were gathered on risk factors such as the presence of subglottic extension, extralaryngeal extension, thyroid gland invasion, lymph node metastasis, timing of tracheotomy, tumor stage, postoperative radiotherapy, and inclusion of the stoma in the radiotherapy field. Results : There were eight cases of subglottic extension, six cases of extralaryngeal invasion, one case of pharyngocutaneous fistula that occurred as a postoperative complication, and one case who was taken completion laryngectomy following conservation surgery. With the exception of one case who was taken tracheotomy prior to total laryngectomy, all tracheotomies were performed intra-operatively after endotracheal intubation. There was no evidence of paratracheal lymph node or prelaryngeal lymph node metastasis on preoperative neck CT scan. There were six cases of T4 tumors, four cases of T3 tumors, and one case of T2 tumor. Salvage surgery was performed following radiotherapy in three cases, and aside from one case who was not taken post-operative radiotherapy, postoperative radiotherapy including the stoma was performed in the remaining seven cases within one month after surgery. Conclusion : Total laryngectomy with wide paratracheal lymph node dissection, thyroidectomy, and tracheotomy should be performed for patients who have high risk factors such as subglottic extension and advanced stage. We believe that tracheotomy should be precede endotracheal intubation. Efforts should be made to prevent stomal recurrence by utilizing postoperative radiotherapy and by minimizing postoperative complications such as infection and fistula.

  • Studies of blood gas and lung histopathology were done in 10 dogs after intrapericardlal aorto-right pulmonary arterial anastomosis with proximal ligation of the right pulmonary antery. Among the 5 expired during or after operation, in 3 cases, the causes of the death were due to surgical bleeding and, in 2 cases, acute cardiopulmonary insufficiency because of large anastomosis stoma measured respectively 7mm and 10mm. In the 5 of survivals, one was sacrificed because of empyema at postoperative 7 days and 2 were at postoperative one month and remained 2 at postoperative 3 month respectively. The following observations were made. 1.In every survival, continuous machinary murmur was auscultated and the angiograms of all long term survivals showed the good patency of the anastomosis stoma. 2.After the ligation of the right pulmonary artery, the values of $PO_2$ and $PCO_2$ in arterial and venous blood were generally decreased comparing with the preoperative values. The mean value of $P_aO_2$ noted $83.30{pm}11.875$[p<0.01]. After the shunts operation with ligation of the right pulmonary artery, the immediate values of PH, $PO_2$ and $PCO_2$showed no significant changes comparing with that of right pulmonary artery ligation only. In the cases of survivals more than one month, the values of $PO_2$ and $PCO_2$ in the arterial and venous blood were generally higher than that of ligation of the right pulmonary artery only. The $P_aO_2$ value noted $103.750{pm}7.395$[p<0.01]. The mean values of $P_aO_2$, $PCO_2$ and PH in the arterial and venous blood almost returned to that of preoperative studies. 3.In the specimens of lung from the cadavors expired due to acute cardiopulmonary insufficiency after the operation, there were massive congestion, hemorrhage in the alveolar spaces and bronchioles. In specimens obtained at postoperative one month, there were dilatation of alveolar spaces with partial rupture, slight congestion, and alveolar wall thickening in the lung parenchyme, but there was no significant changes in pulmonary vasculature except dilation of pulmonary capillaries. In the specimens obtained at postoperative three months, the alveolar walls were more thickened in the lung parenchyme than the finding of the specimens obtained at postoperative one month. In the wall of pulmonary capillaries, there was only slight thickening with connective tissue proliferatlon.

  • The objective of this study was to identify the effects of ozone on the two species in controlled environment. $Sedum$ $kamtschaticum$ and $Hosta$ $longipes$ were exposed in both control and ozone chamber to investigate photosynthesis, antioxidant enzyme activity, visible damage, the number and the size of stomata and the plastogloubuli. Ozone was fumigated in the concentration of $200{\mu}g{\cdot}kg^{-1}$ for 8 hours in a day (from 08:00 AM to 04:00 PM). Firstly, net photosynthesis of two species was decreased after ozone fumigation. Secondly, glutathione reductase activities showed significant difference between control and ozone treatment. Thirdly, visible symptoms of leaves were expressed such as chlorosis, necrosis and decoloration. Also, the size of stoma was significantly decreased in ozone-exposed plants. Furthermore, the intercellular space of $Hosta$ $longipes$ showed increased phenomenon because the mesophyll was collapsed. The number and the size of the plastogloubuli were significantly larger in ozone stress.

  • Purpose: This study was designed to construct and test the structural equation model on sexual satisfaction in patients with a colostomy. Methods: The model construction was based upon Roy's adaptation model. Stoma-related discomfort (SRD), age, frequency of sexual intercourse, treatment modality, and gender affect sexual satisfaction and are mediated by physical, psychosocial, and interdependence modes. Each mode was conceptualized as sexual function, body image/ depression, and marital intimacy. The patients were 112 colostomates with colorectal cancer who were asked to complete a mail-back survey on their demographic data, SRD, body image, depression, marital intimacy, sexual function, and sexual satisfaction. Data were analyzed using SPSS WIN 15.0 and AMOS WIN 7.0. Results: Significant variables for sexual satisfaction in the final model were body image affected by SRD, depression affected by body image and SRD, marital intimacy affected by depression, and sexual function affected by marital intimacy. Conclusion: The results of this study suggest that specific guidelines for SRD are necessary to improve sexual satisfaction among colostomates. Nurses should be vigilant in monitoring depression and body image disturbance, and providing appropriate interventions to increase marital intimacy. Treatment modality, gender, and age should be considered in developing education programs pertaining to sexuality.

  • Acrobeles ciliatus (von Linstow, 1877) and Plectus parietinus (Bastian, 1865) are newly collected from Korea. Acrobeles is similar to those nematode belongs to Rhabditidae and Panagrolaimidae by having terminal bulb without medium bulb but different by having complex, vines shaped labial attachment. A. ciliatus differed from other Acrobeles species by lateral fields with two incisures, primary axils U-shaped, and secondary axils V-shaped. Head region set off with the neck, three high labial probolae present, each having 5 tines at inner margins and 5-7 at outer margins, and two elongate apical tines. Also, it differs from the longer female body. Plectus parietinus is distinguished from all other species of Plectus by the prominent hypodermal glands, the relatively small amphid, the distinct and well set-off lips and by the subdorsal distal caudal seta on the left side of the tail. Stoma without stylet. Oesophagus about 1/4 of total body length with terminal bulb. Anus ca. $100{\mu}m$ from posterior extremity. Vulva is at middle of body. Have spinneret on tail tip.

  • The present treatment of respiratory failure, using cuffed endotracheal and tracheostomy tube has produced, apparently with increasing frequency, three lesions which have serious ceminical manifestations such as tracheal stenosis, tracheomalasia, and localized tracheal erosion. Extensive resection and reconstruction of the trachea must be necessary because conservative treatment has generally failed in the fully developed stenotic lesion. of the mediastinal trachea following extensive resection is best accomplished by direct anastomosis of the patient`s own tracheobronchial tissue. Any replacement of the mediastinal trachea must be air tight and laterally rigid, and must heal dependably. A variety of materials has been used for substitution following circumferential excision of tracheal segments within the mediastinum. These attempts have often failed because of early leak or late stenosis. We have successfully performed circumferential resection and primary end-to-end anastomosis of the trachea for 4 cases of post-intubation tracheal stenosis located a few centimeter below the tracheostomy stoma in the period of 3 years between 1974 and 1976. The lesion in one patient was found in the upper trachea which was approached anteriorly through a cervicomediastinal incision with division of the upper sternum. Other three located in the lower half of the trachea were operated through a high transthoracic incision with appropriate hilar mobilization in addition to cervical flexion for the development of the cervical trachea into the mediastinum. There were no hospital death, but suture line granulations occurred in two patients were managed by bronchoscopic removal of granulations without difficulties.
