The exposures to carbamate pesticides (BPMC specifically) of agricultural workers were estimated by collecting pesticide in air by personal sampler and by analyzing with gas chromatography. Data revealed that the highest BPMC concentration in the aspirated air was 7.7 mg/m3. Concentrations were generally higher in the group whose spray conditions were controlled than the group uncontrolled. Actual concentrations were relatively lower than the values predicted theoretically. These findings suggest that personal sampler be useful in the estimation of pesticide exposure.

The purpose of this study is to observe histopathologic changes in the bilateral craniomandibular joints after allowing 6 weeks of consolidation by varying the amount of distraction in rabbit mandible. Eight rabbits weighing about 2 to 3kg were used. After corticotomy was performed on the left mandibular body between the first premolar and the second premolar region, a unilateral fixation device was placed. Then, a 7-day period was allowed without distraction of the device. The mandible was lengthened 0.5mm/day. Corticotomy and lengthening of mandible were not performed in control group. After the completion of the lengthening process, a 6-week-consolidation period was allowed. Then, the rabbits were sacrificed, and histologic examination of the craniomandibular joints was performed. Proliferative changes were observed in the craniomandibular joints in all groups. With the increasing amount of distraction, hypertrophy of the cartilage layer became more severe, bone formed was dense and enchondral ossification was clearly shown in subchondral bone. Hypertrophy of the cartilage layer was also seen in the non-distracted side as the distracted side in the experimental group. These results indicate that when physical force is applied constantly to joints, the proliferation of articular cartilage and bone formation are present. When more than 6 weeks of consolidation period is allowed at the time of performing distraction for more than 5mm, articular changes, especially, in the contralateral side should also be noted.

BACKGROUND: Nitric Oxide (NO) has been discovered to be an important endothelium-derived relaxing factor. The exogenous inhaled NO may diffuse from the alveoli to pulmonary vascular smooth muscle and produce pulmonary vasodilation, but any NO that diffuses into blood will be inactivated before it can produce systemic effects. To examine the effects of NO on pulmonary and systemic hemodynamics, NO was inhaled by experimental dogs in an attempt to reduce the increase in pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) induced by hypoxia in dogs. METHODS: Eight mongrel dogs were studied while inhaling 1)50% O2 (baseline), 2)12% O2 in N2 (hypoxia), 3)followed by the same hypoxic gas mixture of O2 and N2 containing 20, 40 and 80 ppm of NO, respectively. RESULTS: Breathing at FIO2 0.12 nearly doubled the pulmonary vascular resistance from 173 56dyn sec cm-5 to 407 139dyn sec cm-5 and significantly increased the mean pulmonary artery pressure from 16 3mmHg to 22 4mmHg. After adding 20~80 ppm NO to the inspired gas while maintaining the FIO2 at 0.12, the mean pulmonary artery pressure decreased (p<0.05) to the level when breathing oxygen at FIO2 0.5 while the PaO2 and PaCO2 were unchanged. The pulmonary vascular resistance decreased significantly and the right ventricular stroke work index returned to a level similar to breathing at FIO2 0.5 by addition of NO into the breathing circuit. Pulmonary hypertension resumed within 3~5 minutes of ceasing NO inhalation. In none of our studies did inhaling NO produce systemic hypotension and elevate methemoglobin levels. CONCLUSIONS: Inhalation of 20~80 ppm NO selectively induced pulmonary vasodilation and reversed hypoxic pulmonary vasoconstriction without causing systemic vasodilation and bronchodilation. Methemoglobin and NO2 were within normal limit during the study.

PURPOSE: The Purpose of this study was to explain the effects of aromatherapy massage on the preoperative anxiety of hemorrhoidectomy patients, and to provide the effective and holistic nursing care to them. METHOD: The research design was a nonequivalent control group non-synchronized design. The data were collected during the period from November 1 to November 30, 2003 at K-Hospital in Seoul. The subjects were fifty patients who were to have a hemorrhoidectomy under general anesthesia. They were assigned to two groups, 25 subjects to the experimental group and 25 subjects to the control group. The State Anxiety Inventory tool was used to measure state-anxiety on all patients the day before surgery. Systolic and diastolic blood pressure, and pulse rate were measured on the day before surgery and the preoperative period. The experimental group received aromatherapy massage on the hand with lavender oil. Data were analyzed by x2 test, independent t-test, paired t-test. RESULTS: 1. Hypothesis 1, that the level of preoperative state-anxiety of the experimental group who received aromatherapy massage would be lower than that of the control group who did not received aromatherapy was supported(p=.047). 2. Hypothesis 2was that the Physiological index of the preoperative anxiety of the experimental group who received aromatherapy would be lower than that of the control group who did not received aromatherapy. The 1st subhypothesis that "the level of the preoperative systolic and diastolic blood pressure of the experimental group would be less than that of the control group" was not supported. CONCLUSION: Aromatherapy massage can be regarded as a partially effective nursing intervention that relives the preoperative anxiety of surgical patients and stabilizes vital signs.

Gastritis cystica superficialis (GCS) is a rare lesion which is characterized by glandular hyperplasia with regeneration and degeneration in the mucosa and muscularis mucosa. Recently, GCS is revealed as precancerous lesion, but most report has been associated with those found at the site of a gastroenterostomy. So, we report two cases with GCS who had not previous gastric surgery. A 45-year-old woman visited for epigastric discomfort and another 4Q-year-old woman for epigastric pain. They had not undergone any gastric surgery. The gastroscopy discovered one polyp on anterior wall of greater curvature, upper body and another polyp in the center of the fold of greater curvature, lower body. We removed it by snare polypectomy and the histologic finding showed the character of GCS.

Acrodermatitis enteropathica(AE) which starts in early infancy after weaning is a rare hereditary chronic disorder of zinc absorption. AE is characterized by alopecia, diarrhea and skin lesions localized to periorificial areas and acrally on the extremities. However, recent reports presented Transient Symptomatic Zinc Deficiency(TSZD) in preterm infants. TSZD is clinically similar to AE and skin lesions rapidly heals after zinc supplementation. When the treatment was withheld, no recurrence was seen. We experienced a TSZD case in a cow's milk fed, preterm infant, so We report it with a brief review of literature.

The patients with abdominal surgery usually have acute pain. It is important for a patient's quality of life and for good recovery after surgery to control the postoperative pain. The purpose of this study is to identify the relationship between emotional state of preoperative patients and postoperative pain. The participants in this study were the 100 patients receiving abdominal surgery who received Intravenous Patient Controlled Analgesia (IV-PCA) at the end of the operation. The data were collected using questionnaires and the period of the data collection was from March to August, 2001. The instruments used for this study were The State-Trait Anxiety Inventory (STAI) Developed by Spielberger (1972), The Center for Epidemeologic Studies-Depression (CESD) scale and Visual Analog scale (VAS). The data were analyzed using descriptive statistics, t-test, ANOVA and Pearson Correlation coefficient with the SPSS program. The results are as follows. 1.For general characteristics there were significant differences in the degree of trait anxiety according to gender (p= 0.0010), marital status (p=0.0122), religion (p=0.0040), education (p=0.0001), occupation (p=0.0002), monthly income (p=0.0001), diagnosis (p=0.0001), and operation title (p=0.0001). 2.For general characteristics there were significant differences in the degree of state anxiety according to gender (p= 0.0023), education (p=0.0073), monthly income (p=0.0001), diagnosis (p=0.0005), and operation title (p=0.0063). 3.For general characteristics there were significant differences in the degree of depression according to gender (p= 0.0073), occupation (p=0.0469), monthly income (p=0.0001), diagnosis (p=0.012), and operation title (p=0.0033). 4.For general characteristics there were significant differences in the degree of postoperative pain according to gender (p=0.0213), marital status (p=0.0082), education (p=0.0016), occupation (p=0.0128), monthly income (p=0.0008), diagnosis (p=0.0007), and operation title (p=0.0008). 5.The relationship between trait anxiety and postoperative pain revealed a significant positive correlation (r=0.51, p=0.0001), and the relationship between state anxiety and postoperative pain revealed a significant positive correlation (r=0.50, p=0.0001), and the relationship between Depression and pain revealed a significant positive correlation (r=0.49, p=0.0001).
