Lymphangioleiomyomatosis, a rare disease in women of childbearing age, is the result of benign nodular hypertrophy of the smooth muscle of the lypmhatics and other tissues of the abdomen and thorax. We report a 36-years-old woman with pulmonary and retroperitoneal lymphangioleiomyomat.osis who responded with hormone treatment. She developed vaginal pruritis and a pelvic ultraound was done given her significant past medical history. Ultrasound examination demonstrated a large mass in the right side of her pelvis. Therefore she was admitted to St. Michael's Hospital in Toronto for laparoscopy. Result of cytology was to be consistent with the diagnosis of retroperitoneal lymphangioleiomyomatosis. High resolution CT sacn of the thorax demonstrated multiple small cystic lesions, without associated nodularity compatible with a diagnosis of pulmonary lymphangioleiomyomatosis. She has been taking Provera tablets 100mg po tid since Dec. 15, 1993. We have given her a prescription for Depo provera 500mg IM monthly since she came back to Korea. and made arrangements for regular follow up monthly. We performed chest X-ray, CT of chest(high resolution), abdomen and pelvis, pulmonary function tests and arterial blood gas analysis. Chest X-ray and CT findings showed no significant change since July. 20, 1993.

The rat thoracic aorta was harvested to determine whether either hyperkalemla or hypothermia impairs the endothelium-dependent re axation of the vascular smooth muscle. Isolated thoracic aorta segments were studied in five groups(n=10 in each group). In group I(control), the isolated aortic seglnents were suspended in organ bath without any intervention. In group ll(endotheilum removAl). the endothelium of the aortic segment was removed by gentle rubbing of the intimal surface with a pair of forceps. In group III(457), IV(4mST), and V(3757), the aortic segments were exposed for 45minutes to 4$^{\circ}C$ St. Thomas hospital cardioplegic solution(57 : NaCl, 144.3; KCI, 19.6, MgCl:, 15.7 : CaCl, 2.2 mmol/L).4$^{\circ}C$ modified St. Thomas hospital cardioplegic solution(NaCl, 144.3 : KCI. 140.0 : MgCl:, 15.7; CaCl:. 2.2 mmol/L). and 37$^{\circ}C$ 57, before suspending in the organ bath, respectively. Then, aorta segments were suspended in organ baths(physiologic salt solution, 37$^{\circ}C$, 95% oxygen and 5% carbon dioxide) for Isometric tension recording. The vasodilatation to acetylcholine (10-2 to 10-2mol/L) was not impaired in control, 457, 4mST, nd 3757 groups. The vasodilatation to acetylcholine was impaired in endothelium removal group. The vasodilatation to sodium nitroprusslde (10-2 to 10-2 mol/L) was not impaired in all groups. In conclusion, both hyperkalemia and hypothermia do not alter irreversibly the function of the rondothelium of the thoracic aorta of the rat.

Metabolism of lactate dehydrogenase (EC 1.1.1.27, LDH) was studied to identify the function of LDH-C. Tissues of LDH liver-specific Ldh-C expressed Carassius auratus and eye-specific Ldh-C expressed Lepomis macrochirus after starvation were studied. LDH activity in liver tissue from C. auratus was increased after starvation. And LDH specific activity (units/mg) and LDH/CS were increased in tissues. It means the anaerobic metabolism was taking place in C. auratus after starvation. LDH B₄ isozyme was decreased in skeletal muscle and increased in heart tissue. LDH C₄ isozymes those showed in eye and brain tissues were identified as liver-specific C₄ isozymes and disappeared after starvation. And C hybrid in eye, A₄ isozyme in brain, and both C hybrid and C₄ isozyme in liver tissue were increased, respectively. In L. macrochirus, the level of variation of LDH activities was low but greatly increased especially in eye tissue and LDH A₄ and AC hybrid were increased in brain tissue. The LDH activities in tissues from C. auratus and L. macrochirus remained 30.30-18.64% and 25-18.75%, respectively, as a result of the inhibition by 10 mM of pyruvate. The Km^PYR values of LDH in C. auratus were increased. As a result, LDH liver-specific C₄ isozyme was expressed in liver, brain and eye tissues during starvation. It seems metabolism of lactate was predominant in brain tissue. After starvation, the liver-specific LDH-C was affected more than eye-specific LDH-C.

This work presents o novel method which extract facial region und features from motion picture automatically and controls the 3D facial expression in real time. To txtract facial region and facial feature points from each color frame of motion pictures a new nonparametric skin color model is proposed rather than using parametric skin color model. Conventionally used parametric skin color models, which presents facial distribution as gaussian-type, have lack of robustness for varying lighting conditions. Thus it needs additional work to extract exact facial region from face images. To resolve the limitation of current skin color model, we exploit the Hue-Tint chrominance components and represent the skin chrominance distribution as a linear function, which can reduce error for detecting facial region. Moreover, the minimal facial feature positions detected by the proposed skin model are adjusted by using edge information of the detected facial region along with the proportions of the face. To produce the realistic facial expression, we adopt Water's linear muscle model and apply the extended version of Water's muscles to variation of the facial features of the 3D face. The experiments show that the proposed approach efficiently detects facial feature points and naturally controls the facial expression of the 3D face model.

The aim of the present study was to evaluate the variation in ultimate pH of commercial populations of pure-breed (Landrace, Duroc and Yorkshire) pig's longissimus muscles and their effect on objective meat quality traits and sensory characteristics. Fifty boars were sampled from 184 pigs, which were reared at three breeding farms and slaughtered at a commercial abattoir. The selection was determined based on ultimate pH, and animals were segregated into three groups: low pH (pH $\leq$ 5.5, n=13), medium pH (pH 5.5 to 5.6, n=18) and high pH (pH $\geq$ 5.6, n=16). The breeds had no significant effects; however, pigs with a higher ultimate pH had significantly (p<0.05) higher intramuscular fat content, lower level of polyunsaturated fatty acids, lower level of lipid oxidation and higher eating quality compared to those with lower ultimate pH. As the ultimate pH increased, the relative proportion of C14:0, C16:0 and C18:1 increased while C18:2n6 and C20:4n6 decreased. The present study demonstrates that the economic value of pigs can be characterized by the ultimate pH and/or intramuscular fat content. However, these results do not necessarily indicate that a high ultimate pH directly corresponds to high intramuscular fat content and vice versa.

Parkinson's syndrome is a degenerative brain disease that presents characteristic motor symptoms of tremor, rigidity, and gait disturbance. In addition to these motor symptoms, Parkinson's syndrome also presents non-motor symptoms (NMSs) such as sleep disturbance and cognitive decline. NMSs reduce patient's quality of life and psychosocial functioning and cause economic burden on the patient, so appropriate evaluation and treatment are required. Lewy body dementia is one of the several diseases belonging to Parkinson's syndrome. Its symptoms such as cognitive function, memory impairment, and hallucinations occur with Parkinsonism. Although drug therapy is being used with drug treatment to treat non-motor symptoms, it has limitations such as side effects, which stimulated interest in other complementary treatment methods such as oriental medicine treatment, dance, and yoga. The patient in this case complained of tremor in the right upper extremity, muscle hypertension and pain, and persistent vision, memory, and cognitive decline. The patient was diagnosed with probable Lewy body dementia. The patient was hospitalized for 4 months and received acupuncture and herbal medicines. After treatment, the patient's NMS scale scores decreased from 90 to 63, and the Unified Parkinson's Disease Rating Scale scores (summed I, II, and III) decreased from 17 points to 8 points. The Beck Depression Inventory score decreased from 22 points to 13 points. In addition, the patient's subjective evaluation revealed improvement. In this case, a patient diagnosed with probable Lewy body dementia who did not respond to the standard treatment and did not want to take medications showed improvement in not only motor symptoms but also NMSs after integrative Korean medicine treatment.

Objectives: The aim of this study was to demonstrate the benefit of Traditional Korean Medicine as an adjuvant therapy in management of mid-trimester oligohydramnios. Methods: It is a case report of a 31 year-old woman hospitalized for oligohydramnios at $24^{+4/7}$weeks of gestation. This patient diagnosed with special oligohydramnios had no abnormal findings such as fetal urinary abnormalities or other anomalies. Also, symptom of PPROM (preterm premature rupture of membrane) was not confirmed. The decoction, Gami-danggui-san (DG) was prescribed for the purpose of reducing unnecessary contraction of uterine muscle during pregnancy and promoting blood circulation and metabolism, thereby improving placental function and contributing to the increase of the fluid. DG decoction was administered twice a day until 19th of June, which was 10 days in total. During the treatment, level of amniotic fluid had been monitored by measuring AFI (amnioti fluid index). Results: After these conventional therapies, the amount of amniotic fluid increased steadily, and eventually reached the optimal level. AFI was found to be 3.2 on the $24^{+4/7}$ weeks, 8 on the $26^{+1/7}$ weeks, 11.5 on the $27^{+0/7}$ weeks of gestation. In the same periods, EFW (expected fetal weight) was also found to be increasing gradually: 545 g, 630, and 760 g. Conclusions: Our report implies the potential of herbal medicine as a effective therapy for oligohydramnios tratment. Further studies are needed to assess the efficacy of TKM herbal medicine and reveal the mechanisms of the decoction.

L-carnitine is found in high levels in muscle tissues. It has been developed as a nutrient and dietary supplement, and also used as a therapeutic supplement in various diseases including type II diabetes, osteoporosis and metabolic neuropathies. However, it is not fully understood how it affects cellular mechanisms in colorectal cancer. Therefore, we attempted to determine the effect of L-carnitine in HCT116 human colorectal cancer cells. First, the HCT116 cells were exposed to L-carnitine for 24 hours at 0-40 mM, and then analyzed for cellular proliferation, oxidative stress and related mechanisms. In a MTT assay, L-carnitine inhibited cellular proliferation and induced reactive oxygen species (ROS) in HCT116 by DCF-DA analysis. To analyze the mechanism of L-carnitine in colorectal cancer cells, we performed a western blot analysis for pERK1/2 and pp38 MAP kinase. The western blot showed that L-carnitine significantly increased protein levels of pERK1/2 and pp38 compared with control. Taken together, we found that L-carnitine has anti-proliferative function via increased ROS and activation of ERK1/2 and p38 pathway in HCT116. These findings suggest that L-carnitine may have an anti-proliferative role on colorectal cancer.

This study aimed to find out the effects of oral health education between the experiment group and the control group upon motivating them using oral facial program in 56 subjects including 29 members in the experiment group and 26 in the test group. With the collected data, Wilcoxon signed rank test was performed to understand the difference before and after the program. OHBI in the experiment group showed significantly higher than the control group (p<0.05), mean values after the program with $9.57{\pm}1.44$ and $8.68{\pm}1.46$ points in the experiment group and the control group, respectively. Mean QHI score in the experiment group was $1.00{\pm}.14$ points after the program while that in the test group was $1.03{\pm}.23$, demonstrating lower in the experiment group but not statistically significant. Mean scores of program satisfaction level were $4.13{\pm}.17$ and $3.94{\pm}.22$ points in the experiment group and the control group, respectively, demonstrating statistically significant. Based on the study results, the effects of oral health education using orofacial program showed the differences between the groups in dental plaque index and oral health behavior index. It is worth to use the oral facial exercise program as a tool for improving the authoring function and oral hygiene.

A beautiful smile is made when it is symmetrical and gums are displayed less than 2 - 3 mm. Excessive gingival display also known as "gummy smile" is often recognized to be unaesthetic. Causes of gummy smile can be caused by delayed eruption, vertical maxillary excess, hypermobile upper lip, or a short upper lip. Meanwhile botulinum toxin which is an exotoxin produced from Clostridium botulinum, works by blocking the release of acetylcholine from the cholinergic nerve end plates leading to inactivity of the muscles. The application site and weakens the muscle tone is drawing attention as a gummy smile treatment caused by hypermobile upper lip. There have been many studies about the method of injecting botulinum toxin into muscles around the lips, but there is still no standardized research method and treatment method, so there is controversy over the therapeutic effect. The aim of this study is to review the previous studies about the predictors of indication and effects of gummy smile treatment using botulinum toxin injection. Especially we tried to propose a protocol for optimal dose and efficient injection point through the anatomical considerations for gummy smile treatment using botulinum toxin.
