  • Treatment with implants of single tooth missing cases is both functional and esthetic. Although the success rate of single-tooth implant treatments is increasing, sometimes it makes some problems. Problems with single-tooth implant treatments include soft tissue complications, abutment screw fracture, and most commonly, abutment screw loosening, and these involve the instability of the dental implant-superstructure interface. This study investigated and compared dental implant screw joint micromotion of various implant system with external connection or internal connection when tested under simulated clinical loading, Six groups (N=5) were assessed: (1) Branemark AurAdapt (Nobel Biocare, Goteborg, Sweden), (2) Branemark EsthetiCone (Nobel Biocare, Goteborg, Sweden), (3) Neoplant Conical (Neobiotec, Korea), (4) Neoplant UCLA (Neobiotec, Korea), (5) Neoplant 5.5mm Solid (Neobiotec, Korea), and (6) ITI SynOcta (Institute Straumann, Waldenburg, Switzerland). Six identical frameworks were fabricated. Abutment screws were tightened to 32-35 Ncm and occlusal screw were tightened to 15-20 Ncm with an electronic torque controller. A mechanical testing machine applied a compressive cyclic load of 20kg at 10Hz to a contact point on each implant crown. Strain gauge recorded the micromotion of the screw joint interface once a second. Data were selected at 1, 500, 5,000, 10,000, 20,000, 30,000, 40,000 and 50,000 cycle and 2-way ANOVA test was performed to assess the statistical significance. The results of this study were as follows; The micromotion of the implant-superstructure in the interface increased gradually through 50,000 cycles for all implant systems. In the case of the micromotion according to cycle increase, Neoplant Conical and Neoplant UCLA system exhibited significantly increasing micromotion at the implant-superstructure interface (p<0.05), but others not significant. In the case of the micromotion of the implant-superstructure interface at 50,000 cycle, the largest micromotion were recorded in the Branemark EsthetiCone, sequently followed by Neoplant Conical, Neoplant UCLA, Branemark AurAdapt, ITI SynOcta and Neplant Solid. Internal connection system showed smaller micromotion than external connection system. Specially, Neoplant Solid with internal connection system exhibited significantly smaller micromotion than other implant systems except ITI SynOcta with same internal connection system (p<0.05). In the case of external connection, Branemark EsthetiCone and Neoplant Conical system with abutment showed significantly larger micromotion than Branemark AurAdapt without abutment (p<0.05).

  • Soybean plants inoculated with Bradyrhizobium japonicum MN 110 were supplied with nutrient solutions containing 1.0, 0.25 and 0.5.nM-P to characterize the effect of externaI-P supply on the phosphorus status of nodules and on the P-uptake system of isolated bacteroids from nodules. After 48 days of growth, whole plant dry mass in the 0.25 and 0.05 mM-P treatments decreased significantly. The Pi concentrations in nodules were 4.1, 2.5 and 2.0 mM for 1.0, 0.25 and 0.05 mM-P treatments, respectively. The external-P supply did not significantly affect the distribution of phosphorus among inorganic phosphate(Pi), soluble organic-phosphorus(SOP) and insoluble organic-phosphorus(TOP) fractions in nodules. The Pi concentrations in young leaves of 0.25 and 0.05 mM-P plants were 33% and 20% , respectively, of those in young leaves of 1.0 mM-P plants and Pi concentrations in old leaves were only 16% and 7%, respectively, of those in old leaves of 1.0 mM-P plants. Phosphorus deficiency decreased the percentage of total leaf phosphorus in the Pi fraction and increased the percentage of total leaf phosphorus in the IOP fraction. The bacteroid number ranged from 0.87 to $1.30{\times}10^{11}$ Per GFW nodule regardless of external-P supply to the host Plants and Plant age, The P-uptake rates were the same (15-16 pmoles /min./$10^8$ bacteroids) for the bacteroids isolated from nodules of 1.0 mM-P and 0.05 mM-P plants. These results indicate that Pi concentrations in nodules of phosphorus-deficient plants are sufficient for proliferation of bacteroids and that the P-uptake system of bacteroids is in a repressed state even when host plant growth is severely restricted by phosphorus-deficiency stress.

  • We analyzed the patterns of mineral ions and growth responses among symbiotic nitrogen fixing legumes by external nitrogen applications under salt gradients. Glycine max, Phaseolus angularis and Albizzia julibrissin showed remarkable growth inhibition above 40 mM NaCl treatments, but Cassia tora did not exhibit any visible injury symptom up to 100 mM NaCl treatments. As to ionic pattern, the $Na^+$ and $Cl^-$contents in leaves of G. max, P. angularis and A. julibrissin progressively increased with higher contents of external salinity. Compared to other plants, C. tora excluded $Na^+$more efficiently and maintained rather constant ionic contents in spite of high salt levels. With a few exception, these 4 legume plants exhibited better growth by the external nitrogen supply rather than the contribution of symbiotic nitrogen fixation only under saline condition.

  • Objectives : The purpose of this study is to report the effect of Korean medical treatments on idiopathic bilateral strabismus. Methods : We treated a 43-year-old male idiopathic bilateral strabismus patient who was told to wait without a prescription as there was no problem in intraocular pressure test, fundus test, brain computed tomography, brain magnetic resonance imaging and angiography test, and cerebrospinal fluid test. The patient was admitted to Cheonan Korean medical hospital for 3 months to get Korean medical treatments including acupuncture, electroacupuncture, vapor treatment, pharmacopuncture therapy. The degree of improvement in idiopathic bilateral strabismus was determined by the objective measures of internal and external rotation disorders, and the patient's subjective opinions on eye pain and double vision discomfort. Results : The results of this patient showed distinct improvements on objective measures of internal and external rotation disorders in both eyes. Distance from the outer corner of the right eye when abducted decreased from 7mm to 0mm, and left eye decreased from 7mm to 0mm. Distance from the inner corner of the right eye when adducted decreased from 5mm to 0mm, and left eye decreased from 4mm to 0mm. In addition, eye pain decreased from 10 to 0 and diplopia decreased from 10 to 2 according to the patient's subjective opinions. Conclusions : This study shows the possibility that such medical treatment in Koreans can improve the rare idiopathic bilateral perspective among strabismus patients.

  • To investigate changes of estrus signs and genital organs in the bitch by hormonal induction of estrus, fourteen bitches of nulliparous and multiparous(2nd-5th) were grouped into diestrus and anestrus according to their estrus cycle. The hormonal treatments were divided into four groups: group A($PGF_2{\alpha}+PMSG+hCG$) and group B(PMSG+hCG) in diestrus bitches and group C(GnRH+FSH+hCG) and group D(PMSG+hCG) in anestrus bitches. The external signs of proestrus and estrus as well as the vaginal smear findings and natural breeding as estrus detection were investigated in all the experimental groups. Also, genital organs were examined at two months after the hormone treatment. The bitches in anestrus showed 100% of male attraction, vaginal bleeding and vulvar swelling as proestrus signs after the hormonal treatment for estrus induction and they showed higher numerical value of signs than the bitches in diestrus. The group A showed the lowest value in proestrous signs of all the groups. The bitches in anestrus treated with GnRH+FSH showed 100% of positive estrus by vaginal smear findings and 75% of natural breeding as estrus detection index and these values were the highest of all the groups. Pregnancy was recognized in only group C and the conception rate was 7.14% in al the experimental animals. Of the side effects after the hormone treatment, external findings of continous male attraction, continous external swelling and purulent exudate were recognized in all the experimental groups and the bitches in diestrus showed higher value of the findings than the bitches in anestrus. Of the changes of genital organs after the hormone treatment, hypertrophy of uterine horn, sanguineous exudate and purulent exudate as uterine findings were recognized in all the groups and these findings were shown more in the bitches in diestrus than in those in anestrus. These results indicated that group C showed the highest value of all the experimental groups in external signs of estrus and estrus detection and also pregnancy was recognized only in that group, consequently, that the hormonal treatment of group C would be the most effective for estrus induction, and also indicated that bitches in anestrus were more suitable than bitches in diestrus for the induction of estrus. In addition, side effects in external genital organs and uteri after hormone treatment were shown more in the bitches in diestrus than in those in anestrus, indicating that bitches in anestrus would be of choice for estrus induction.

  • Objectives : The objective of this study is to review external approaches using acupuncture and related treatments of hyperpigmentation disorders and their classification in traditional medicine. Methods and Results : Hyperpigmentation was recorded for the first time in Treatise on the Pathogenesis and Manifestations of All Diseases published in 610 A.D. This suggests that the symptom has already been recognized as an independent disease in East Asia for more than 1,400 years. Over the course of several centuries, there has been a significant evolution in the traditional treatments for hyperpigmentation. There are many different types of therapy, including body acupuncture, intradermal acupuncture, ear acupuncture, ear acupressure, blood-letting treatment, pharmacopuncture, plum-blossom needle therapy, burning acupuncture therapy, moxibustion, and guasha. In addition, the traditional classification of hyperpigmentation has been changing shape. However, no attempts have been made to establish the academic linkage between the modern classification of hyperpigmentation disorders and the traditional one, on account of different concepts and names of the ailment. This study was designed in an attempt to identify the linkage of the categorization of the Korean Standard Classification of Disease (KCD) and the traditional classification. Conclusions : Through this literature review, we found that there has been a significant evolution in the treatment of hyperpigmentation disorders in East Asia. Traditional medical treatment for skin disease, including hyperpigmentation, is expected to be further developed with the advancement of science and technology.

  • Objective : The objective of this study is to analyze an increasing rate, difference of attack rate in age, relationship between atopic dermatitis and breast-feeding, the relationship between atopic dermatitis and the Sasang constitution, and various treatments of atopic dermatitis. Methods : This clinical study was carried out with 22 theses which are related with diagnosis, treatments, prognosis and control of atopic dermatitis. The 22 theses are carried on J Korean Oriental Pediatrics, J Korean Oriental Ophthalmology, J Korean Oriental Med, J Korean Academy of Pediatric Allergy and Respiratory Disease, J Korean Acad Fam Med and Korean J Food & Nutr. Results : The prevalence rate, attack rate and diagnosis rate of atopic dermatitis are increased in the year of 2000, compared with those of 1995. Comparing age of patient between the year of 1992 and 2002, the attack rate of atopic dermatitis is increased quickly over 7 years old. Specific immunoglobulin E(IgE) antibodies detected in patients under 1 year old was exclusively caused by food. But for the age over 7 years old, food and inhalant allergen are detected in the year of 2002 in compare with that of 1992. Because of breast-feeding, intemperate diet adjustment during the period of maternity of family history of atopic dermatitis, the attack rate of atopic dermatitis is increased in infant. The types of patients are categorized according to Sasang constitution and Soeumin group was largest. The Oriental medicine treatments of atopic dermatitis are bath & skin hydration, avoidance from antigen, dietetic treatment, external treatment, medication and phototherapy. Conclusion : The atopic dermatitis is associated with breast-feeding, Sasang constitution types. More active approach for the treatment and prevention of Atopic dermatitis in children are needed.

  • The effects of replacement of wheat flour with 10, 20, and 30% chestnut flour on the bread-making properties and quality characteristics of bread were evaluated. Among the physical characteristics of the dough, the development time in the farinogram decreased with increasing amounts of chestnut flour, and the dough stability and durability were reduced. In the amylogram, there was a slight increase in the gelatinization starting temperature when compared to the control flour, but the maximum viscosity gradually decreased in response to increasing amounts of chestnut flour. The expansion ratio did not increase in the dough containing 20 or 30% chestnut flour. Moreover, the loaf volume and specific volume of bread containing 20 and 30% chestnut flour were smaller than those of the control and the 10% treatment. The hardness of bread containing 10% chestnut flour($700g/cm^2$) was lower than that of the other treatments($1413-1,627g/cm^2$). Furthermore, bread containing 10% chestnut flour had denser porous structures than the other treatments. The sensory evaluation tests revealed that the 10% treatment had higher sensory scores for the internal and external qualities of bread than the other treatments.

  • Objectives : This study was conducted to review the research trends in Korean Medicine of pompholyx based on publications in Korea. Methods : Literature published after 2000 were collected using OASIS, NDSL, KISS, and key words searched were "한포진" "발한이상" "pompholyx" "dyshidrotic eczema". Results : 10 case reports and 4 patient studies were selected for study. Conclusions : Korean medicine treatments included acupuncture, pharmacopuncture, venesection therapy, herbal medicine, ointments and carbon arc lamp therapy. The most commonly used diagnostic method for pompholyx was inspection along with pulse diagnosis, abdominal diagnosis, tongue diagnosis, culture test, and KOH smear screening. The most frequently used treatment evaluation method was Likert scale while VAS(Visual Analog Scale) and Visual&Subjective symptoms were each used in 4 studies. Among 29 patients in 14 papers who showed clinical manifestations of pompholyx, there were 15 male patients (52%), 14 female patients (48%), and the male to female ratio showed 1.07:1. Symptoms were improved using Korean Medicine treatments including acupuncture and herbal medicine. Concurrent treatment using special treatments such as pharmacopuncture, jiyang-go, bojungikgi-tang(ex), external applications showed higher treatment effects. Korean medical treatment of pompholyx was effective in all studies, but the lack of numbers of research on Korean medicine of pompholyx was witnessed compared to other diseases such as psoriasis. Also considering the number of patients suffering from pompholyx, further studies should be conducted.
