The vestibular system is a sensory motor system concerned with the sensation of linear or angular acceleration, eliciting several vestibular postural reflexes. This study was designed to figure out the functional relationship in vestibulocollic reflex. The electromyographic responses of the cervical muscles were observed during stimulation of the horizontal semicircular canal nerves. The sternomastoid muscle was inhibited by stimulation of the ipsilateral horizontal canal nerve and excited by stimulation of the contralateral horizontal canal nerve. The splenius capitis muscle was inhibited by stimulation of the ipsilateral horizontal canal nerve and excited by stimulation of the contralateral canal nerve. The semispinalis capitis revealed same pattern responses as splenius capitis or sternomastoid muscles to stimulation of the horizontal canal nerve. These experimental results indicate that the cervical extensor or flexor muscles respond in a uniform fashion to the stimulated horizontal canal nerve. And taken these results and other morphological study results together, the excitatory neural pathways from the vestibular nucleus in brain stem to cervical motoneurons are crossed to the opposite side but the inhibitory pathways from the nucleus to the cervical motoneurons are uncrossed.

The purpose of the survey was to identify the degree and the relationship of sexual knowledge, sexual attitude. This information will provide useful data for a more systematic, desirable, and practical sex education. The data was collected from 187 first grade schoolchildren(95 boys and 92 girls) of two Junior high school in Chun-nam area. The data was gathered by questionnaire from Oct. 1 to 15, 1996. The questionnaire was modified by authors using the questionnaire developed by You-Jeong, Han(1996). Data was analyzed by using the statistical computer package, SAS to manipulate the data long with percentages, means, standard deviation, t-test, chi2-test, GLM, and Pearson correlation coeffiency. The results in this study were summarized as follows : 1. Sex related knowledge. - The mean score of sex related knowledges showed significant differences between boys and girls(boys ; 22.3, girls ; 21.0, p<0.025), and in the area of pregnancy & delivery(boy ; 9.4, girls ; 7.9, P<0.000) showed significant difference between boys and girls, but in the area of physical differences of the others sex(boys ; 12.9, girls ; 13.1, p<0.551) showed no significant difference between boys and girls. 2. Sex related attitudes. - The mean score of sex related attitudes showed significant difference between boys and girls(boys ; 56.7, girls : 60.5, p<0.002) and in the area of psychological difference the other sex(boys : 28.9, girls : 32.5, p<0.000), but in the areas of form of friendship with the other sex(boys : 11.5, girls : 11.2, p<0.335), sexual delinquency & its prevention(boys : 16.3, girls : 16.9, p<0.171) showed no significant difference between boys and girls. 3. The relationships between sex related knowledges and sex related attitudes. - Those who had higher sex related knowledges showed more positive attitudes towards sex, and showed no statistical significance(r=0.08, p<0.286). 4. Differences of the sex related knowledges according to general characteristics. - The students had disease experience, health interest and more school performance had higher knowledge scores about sex. 5. Differences of the sex related attitudes according to general characteristics. - Those who were in high school performance had higher attitude scores about sex as well..

To make better clinical diagnosis, authors reviewed 9 patients of nonchromosomal multiple malformation disorders with psychomotor retardation, who were evaluated at pediatric department of Yeungnam University hospital for recent 2 years. We could make clinical diagnosis in 5 patients out of 9 as Aarskog syndrome, BeckwithWiedemann syndrome, Hallermann-Streiff syndrome, Rubinstein Taybi syndrome and Weaver syndrome. But even in diagnosed cases, there were many discrepant findings in comparison with typical cases of reference literatures and family history was positive in only one case. Moreover we could not make diagnosis in 4 patients. Therefore we think it is necessary to make a survey of unique pattern, incidence, distribution and etiologic factors of malformation disorders in our country by geneticist and pediatrician as well as to improve the laboratory aids for better diagnosis and genetic counseling.

Six cases of congenital coronary arteriovenous fistulae were diagnosed radiographically and confirmed afteroperation at Seoul National University Hospital in recent three and a quarter years since 1979. The clinical andradiological findings with the emphasis on the cinecardiographic findings were analysed. The summaries of theanalysis are as follows; 1. Among 6 cases, 2 cases were male and 4 cases were female. Age dsitribution was from 3months to 19 years. 2. In chest x-ray findings, 5 cases had cardiomegaly. Among these 5 cases, increase ofpulmonary vascularity was in 3 cases. Chest X-ray finding of the rest 1 case was within normal limit. 3. Thecoronary arteriovenous fistula orginated from the right coronary artery in 5 cases and from the single left coronary artery in 1 case. In 5 cases, a coronary arteriovenous fistula drained into the right ventricle and in 1case, a fistula from a SA node branch of the right coronary artery into the right atrium. 4. In 5 cases, a mainright coronary artery was dilated. Among these 5 cases, aneurysmal dilatation of main right coronary artery was in2 cases, saccular aneurysmal dilatation of distal portion of right coronary artery was in 2 cases and in 1 case,diffuse dilatation without aneurysm formation of a main right coronary artery. In 1 case, SA node branch of theright coronary artery was dilated with aneurysm formation. 5. For accurate diagnosis of congenital coronaryarteriovenous fistula, biplane cinecardiography is an essential procedure.

BACKGROUND: To evaluate the role of free fatty acids on the ischemic myocardium, influences of various free fatty acids upon transmembrane action potential and ATP-sensitive K+(KATP) channel activity were examined in the ventricular myocardium and single cardiac myocytes. METHODS: KATP channel activities were measured in the enzymatically (collagenase) isolated single rat ventricular cardiac myocytes by the method of the excised inside-out and the cell-attached patch clamp, and transmembrane action potentials were recorded using the conventional 3M-KCl microelectode techniques in the rat ventricular myocardium. RESULTS: Free fatty acids [FFAs; arachidonic acid (AA), linoleic acid (LA) and lysophosphatidylcholine (LPC)] reduced the KATP channel activity in a dose-dependent manner in the inside-out patch, and 50%-inhibition concentrations (IC50) were 88 +/- 11.2, 49 +/- 12.5, and 188 +/- 17.4 M respectively. Both frequency of channel opening and the mean open-burst duration were markedly decreased, but the amplitude of single channel currents were not changed by the FFAs. AA (50 micrometer) and LPC (50 micrometer) did not affect the dinitrophenol (DNP, 50 micrometer)-induced KATP channel activity, whereas LA (50 micrometer) had a tendency to reduce the activity. The channel inhibition effects by 10 micrometer AA in the inside-out patch were significantly augmented by diclofenac (10 micrometer), but was not changed by nordihydroguaiaretic acid. FFAs never stimulated KATP channel activity, even in the inside-out patch where KATP channel activity reduced in the presence of internal ATP (100 micrometer). Time for 90% repolarization (APD90) significantly increased during superfusion of the FFAs, to 22 (50 micrometer AA), 24 (50 micrometer LA), and 18 (50 micrometer LPC) % from those of the contol at the time of 10 min superfusion, but the other action potential characteristics were not changed by the FFAs. AA (10 micrometer) attenuated cromakalim (10 micrometer)-induced APD90 shortening effects. CONCLUSION: It was inferred that FFAs inhibit the KATP channel activity directly by themselves and/or indirectly by their metabolites in the rat ventricular cardiomyocytes, and therefore, duration of action potential lengthens to be a burden over the ischemic myocardium accounting for the injury of myocardium at the late stage of ischemia.

PURPOSE: This study identifies research trends and provides fundamental data related to curative power of aromatherapy to relieve pain in Korea. METHODS: The study analyzed 44 experimental studies on humans that were published in Korea before the end of December, 2009. The key words used for searching were: aroma, aromatherapy, hyang-yobeob, hyanggi-yobeob, hyanggichilyo, aromatherapy and pain, headache, scapulodynia, omodynia, feeling uncomfortable in the perineal region, sense of pain, labor pains, arm pain, menstrual pain, aches, and dysmenorrheal. Those words were found on websites, including those for Korea Education & Research Information Service, the National Assembly Library, KISS, KoreaMed, and NDSL. Collected data were analyzed using descriptive statistics. RESULTS: The results showed that most of essential oils to relieve pain is composed of three to four kinds of oils, including Lavender, Roman chamomile, Rosemary, and Clarysage. Aromatherapy is applied usually by means of massage (50%), inhalation (13.6%), or a combination of the above two (13.6%). Measuring instruments as a dependent variable include VAS, questionnaire, GRS, blood pressure, pulse, and Algometer. Aromatherapy plays an important role in soothing headaches and arthralgia. However, when it comes to labor and menstrual pain, it doesn't seem to be effective. CONCLUSION: The study found that different kinds of oil, frequencies, and periods of time are used for the same symptoms. Further research should employ standardized oil blending, application, duration, and measuring instruments, and more systematically analyze the effects of aromatherapy to establish the effects on relieving pain.

OBJECTIVE: The purpose of this study is to evaluate the role of cold knife conization in the diagnosis and management of cervical neoplasia. METHODS: Cold knife conization was performed in total 163 patients from January 1992 to December 2003. The results of PAP smear and colposcopy-directed biopsy were compared with the pathologic diagnosis of conization. And we evaluated the rate of positive margin and the presence of residual lesion. And then, we reviewed the pregnancy outcome after conization. RESULTS: The rate of agreement between PAP cytology and conization was 45.4%, and the rate of agreement between colposcopy-directed biopsy and conization was 65.6%. Hysterectomy was done in 102 patients (62.6%). The positive rate of resection margin was 19.6%. The incidence of residual lesion after conization was 31.2% in margin (+) and 1.4% in margin (-). We evaluated 7 cases of pregnancy after conization. CONCLUSION: Cervical conization as surgical treatment was effective in cervical neoplasia patients, especially young patients, with continuous follow-up.

PURPOSE: In the treatrnent of respiratory distress syndrome, Infants are often exposed to hyperoxia. It can generate oxygen free radical, damage to lung and bronchi, and inactivate pulmonary surfactant(PS). Antioxidant therapy in animal and human models has been tried to overcome this detrimental effects. We hypothesized that the addition of oxygen free radical such as hydrogen peroxide(H) could compromise surface active properties(SAP) of PS and that further addition of antioxidant such as catalaseR(CAT, Sigma chemical, St. Louis) could recover SAP. METHODS: We prepared combinations of mixtures with SurfactenR(S-TA, Tokyo Tanabe, Japan), H202 and CAT. 1)0.625mgPL(phospholipids)/ml or 1.25mgPL/ml S - TA and H202 were mixed to the final concentrations of 0.1 and 1mM H respectively, and incubated at 37C for one hour. 2) 0.625mgPL/rnl S - TA, H202 and CAT 10U were mixed to the final concentrations of lmM H202, and incubated at 37 degree C for one hour. We used Pulsating Bubble Surfactometer (Electronetics, NY) measure in vitro minimum and maximum surface tensions(ST) and area-surface tension relationship. RESULTS: 1) For 0.625mgPL/ml S-TA and 1mM H mixture minimum. ST after 5 min of pulsation increased significantly(P=0.007) and the area-surface tension curve was deformed. But they were comparable to control levels for 1.25mgPL/ml S-TA. 2) When CAT was added to 0.625mgPL/ml S-TA and 1mM H mixture, the resultant minimum ST after 5 min of pulsation dropped to the control levels with recovery of hysteresis curve(P=0.0001). CONCLUSION: PS could be inactivated by addition of high concentrations of H but SAP can be recovered either by increasing PS concentration or by further addition of antioxidant CAT. Therefore, we suggest that in case of suspected surfactant inactivation an increase in surfactant concentration or administration of antioxidant must be considered.
