Li-bearing hectorite, one member of trioctahedral smectite, occurred large in quantity and confirmed in Turkey western sedimentary boron deposit. Li-bearing hectorite attracted a particular attention because it is one of potential lithium resources. There have been no consensus for the change of hectorite due to heat and acid treatment although it is very important to use in industrial application. In this study, we examined changes of hectorite after heat and acid treatment as well as acid treatement followed by heating. We used clay ores collected in Bigadic deposit, which contained the highest $Li_2O$ content in Turkey boron deposits. Hectorite showed a strong endothermic reaction at $84^{\circ}C$ due to dehydration of absorbed water and interlayer water and a weak endothermic reaction above $600^{\circ}C$ owing to dehydration of crystallization water. The first endothermic reaction accompanied a large weight loss about 6%. Hectorite decomposed into enstatite, cristobalite and amorphous Fe material at $762^{\circ}C$ with exothermic reaction. When hectorite reacted with 3 kinds of 0.1 M acid during 1 hours, it had a good dissolution efficiency with $H_2SO_4{\geq}HCl$ > $HNO_3$ in order.

Objectives : The purpose of this study is to compare the effects of Pharmacopuncture Treatment with Chuna Treatments for Low Back Pain caused by Traffic accidents. Methods : This study was carried out on 81 patients with low back pain caused by Traffic accidents. The patients were divided into 2 group ; The pharmacopuncture(A) group was treated by pharmacopuncture treatment. The chuna(B) group was treated by chuna treatment. We measured Oswestry Disability Index(ODI) and Visual Analog Scale(VAS) on the patients before the treatment and on the 2nd, and 4th weeks after the treatments. Results : After being treated by our methods, the ODI and VAS score's were improved after the 4th weeks treatment in both groups. There is no significant difference on ODI and VAS score after the 4th weeks treatment in both groups. In the early stages(from pre to 2 weeks worth of treatment), Group A showed a decreasing VAS score compared to Group B. In the final stages(from 2 weeks to 4 weeks worth of treatment), Group B showed a higher decreasing amount compared to Group A in VAS score. Conclusions : The results suggest that both pharmacopuncture treatment and chuna treatment is considered to be effective and useful on low back pain caused by traffic accidents. There is no significant difference between pharmacopuncture treatment and chuna treatment for low back pain caused by traffic accidents, however the early stages of treatments(from pre to 2 weeks treatement) show that pharmocopouncture treatment is more effective than chuna treatment for low back pain by traffic accidents. In the final stages(from 2 weeks to 4 weeks treatment), chuna treatment is more effective than pharmacopuncture treatment for low back pain by traffic accident.

Purpose: The mortality and the amputation rates due to vascular trauma remain high despite advanced vascular surgical techniques and supportive management. The clinical features of patients with vascular trauma have not been well studied in the Korean population. The aim of this study was to analyze the clinical characteristics of patients with vascular trauma and to develop a database and guidelines for improving the outcomes of treatment. Methods: The medical records of 37 patients with traumatic vascular injuries who had visited in an emergency center between January 2002 and December 2006 were retrospectively reviewed and statistically analyzed. Results: The mean age was 37.8 years, and the male-to-female ratio was 5.2 : 1. The mechanism of vascular trauma was penetrating in 18 patients and blunt in 19 patients. Upper extremities were most frequently injured (39.4%). The treatment methods were primary repair in 21 patients, exploratory laparotomies in 7, radiological interventions in 3, resections and graft interpositions of the pseudoaneurysm in 3, observations in 3 and a bypass graft in 1. Four out of the 37 patients died, and three of these who died had injuried abdominal vessels. Twenty-five of the patients recovered completely, four expired, seven had neuropathy in the course of treatement, one had his limb amputated, and one experienced wound necrosis. Conclusion: Peripheral vessel injuries are commonly accompanied by nerve, muscle, or tendon injuries. Patients without associated fractures or compartment syndrome had good prognosis. Although the time intervals from hospital arrival to definite treatment were the shortest among patients with blunt abdominal vascular injuries, three expired. Therefore, we offer a 'ritical pathway'to improve the outcomes of patients with blunt abdominal vascular injury.

Purpose : Adenoviruses(Ad) have been shown to play an important role in the etiology of severely acute respiratory diseases, particulary in infants and young children, and the occurrence of fatal outcome and chronic pulmonary sequelae in association with adenoviral infection has been a cause of great interest and concern. This report presents the resul of a retrospective analysis on 30 cases of lower respiratory infection from which adenovirus was isolated. Patients & Methods : The 30 patients in this study represent all detected cases of adenovial infection out of 240 children who were admitted to Sang Sung Medical Center between February to June 1996 showing signs and symptoms of lower respiratory tract infection. The diagnosis of adenovirus infection was based on microscopic visualization of typical cytopathic effect in HEp-2 tissue culture and used monoclonal Ab with nasopharyngeal aspiration. Results : The male/female ratio was 2:1 and the majority of age range was below 36months. Clinical diagnoses in all 30 patients were pneumonia(n=21), bronchitis and Bronchiolitis(n=5) and ARDS(n=4). We recieved the most of patients in the month of May. The chief complaints were fever(93.3%) and cough(80%) and extrapulmonary symptoms were diarrhea(n=5), seizure(n=4), abdominal pain(n=1). The mean duration of fever was $11.95{\pm}6.54$days. Physical examination on admission were crackles(73.3%), coarse breathing sounds(60%), hepatosplenomegaly(33.3%), decreased brething sounds(30%). In WBC counts, 8cases were below $4000/mm^3$ and 14 cases were above $10,000/mm^3$. In platelets counts, 4cases were below $150,000/mm^3$ and 10 cases were above $450,000/mm^3$. 21 cases were above 1 in CRP. GOT and GPT were abnormal in some cases. Chest X-ray revealed diffuse pulmonary infiltration(n=15), pleural effusion(n=6), consolidation(n=4) and hyperaeration(n=3). Seven patients were treated at the peditric intensive care unit with respiratory support and high dose of gammaglobulin. However, one patients died even through he was treated with NO ventilation and high frequency ventilation. Conclusion : Those with adenoviral pneumonia and respiratory infection having long fever duration and symptoms like bacterial pneumonia must be carefully differentiated in order to provide proper treatement and preventive measures due to possible fatal outcome.

It has been known that sewage containing high-concentration nitrogen affects the efficiency of municipal wastewater treatment plants harmfully. Therefore, research has been actively conducted to treat sewage containing high-concentration nitrogen. The current study has analyzed organic compounds, conducted foaming tests, and operated a laboratory-level nitritation reactor with the subjects of anaerobic digester supernatant and livestock wastewater which are the typical kinds of sewage containing high-concentration nitrogen. According to the results of analyzing organic compounds, soluble inert components form the largest part of anaerobic digester supernatant while particle biodegradable components occupy the most part of livestock wastewater. About the retention time proper for the reaction of nitritation, anaerobic digester supernatant shows 2 days while livestock wastewater indicates 6 days. It seems that the difference in the proper retention time is resulted from the difference of properties in organic compounds and ammonium nitrogen concentration. In addition, livestock wastewater's reactor foam is generated comparatively more than anaerobic digester supernatant's, but it tends to be eliminated faster. It is expected that the findings of this study can be utilized as foundational data afterwards in applying the reaction of nitritation to municipal wastewater treatment plants.

${\delta}$-Aminolevulinic acid (ALA) is a compound which is widely present in the biosphere and plays an important role in the living body as an intermediate of the tetrapyrrole compound biosynthesis pathway that leads to heme in mammals and chlorophyll in plants. ALA is of interest as a biodegradable mediator, a growth regulator, a precursor of heme proteins, and an effective agent used in therapy of cancer. It has been recently reported that ALA is commonly used in dermatology, due to good effects of skin therapy. Although for the last few decades a substantial amount of research has been focused on the elucidation of the mechanism of ALA and the improvement of its therapeutic activity, it's effect on the cell functions and growth was not cleared. Here, we identified that ALA treatment could attenuate cell proliferation of HEK293T and HaCaT cells. In addition, ALA treatement could induce apoptosis of HeLa cells. These results suggest that apoptosis induced by ALA treatment might be responsible for inhibition of cell proliferation. These results propose the possibility of the improved therapeutic strategy making ALA one of the effective drugs used in human cancers.

A Trichoderma sp. SO-571 producing cellulase was isolated from soil, and a pilot-scale cultivation and separation of cellulase were conducted. The cellulase activity was about 14.5 unit/ml after 112 hr of cultivation in a 301 fermenter containing 3.0% cellulose, 4.0% soybean powder, 3.0% wheat bran, 0.5% ($NH_4$)$_2$$SO_4$0.2% urea, 1.0% CSL, 0.5% $KH_2$PO$_4$, and 0.2% Tween 80. The cellulase was purified over 4.6 folds in three steps with 47.86% yield. The optimum pH of cellulase was pH 5.0 and optimum temperature was $60^{\circ}C$. To investigate the effect of the cellulase-treated cellulosic fabric, the weight loss was compared. The weight loss of denim treated with cellulase from Trichoderma sp.SO-571 was 2.9% and that with Celluclast 1.5L was 2.2%. In tencel treatement with enzyme, cellulase showed 0.7% higer weight loss than that with Celluclast 1.5L.

This experiment was conducted to investigate the mass propagation system of Aster glehni FR. and to obtain the basic data for improvement of germination and seedling. The following was the results of experimentation about temperature and light conditions, and priming treatment as kinds of chemicals, their concentration and treated periods affect germination of Aster glehni FR. The germination percentage of Aster glehni FR. seed was higher in 20 and 25$^{\circ}C$ than the others, but it dropped rapidly at 30$^{\circ}C$ and didn't germinate at 35$^{\circ}C$. The first day to germination was the slowest at 15$^{\circ}C$. The germination rate of Aster glehni FR seed increased with increasing with temperatures from 15 to 25$^{\circ}C$. But the seed was rotten easily in high temperature. The germination rate was shown highest in 25$^{\circ}C$, and next was 15, 20, 30$^{\circ}C$ in order. Light treatment enhanced germination percentage, the first day to germination, germination rate and T50, but there was no significant difference. The 3 hours priming treatments had more effect on germination percentage than 30 minutes treatments as comparing averages. Aster glehni FR seeds primed in $KNO_3+K_3PO_4$ for 3 hours had most eHective on germination percentage (83.3%) and also showed shortest $T_{50{\cdot}}T_{50}$ and day of first germination was better in 30 minutes than 3 hours treatments, and most of priming treatments were better than control(non-priming seeds). While priming seeds showed shorter day of first gemination than control, there was no significant difference between 30 minutes and 3 hours treatments.

Erectile dysfunction (ED), also known as impotence, is the inability to attain and sustain an erection firm enough to have sexual intercourse. Frequent ED may be a symptom of health problems including heart disease, obesity, alcoholism, stress, smoking, and depression, that need treatment. This study aimed to effect of complex extract (CPL) including Cornus officinalis on sexual function factor in the erectile dysfunction rat model. The erectile dysfuction rat model was induced by cimetidine (500 mg/kg in 5% ethanol, oral injection 2 weeks). Rats were oral administered with different concentration of CPL in rat erectile dysfunction model. As a results, sexual function factors (NO, cGMP) significantly improved in CPL treated groups (CPL-300, 600, 900 mg/kg) compared to CON group. Serum testosterone was increased in a dose-dependent manner after CPL treatment. Furthermore, administrations of CPL restored lumen areas of the prostate in the erectile dysfunction rat model. These results indicated that CPL alleviated erectile dysfunction by increasing sexual function factor and testosterone in rat model. CPL could be used to natural treatement for erectile dysfunction. However, further study is required to identify active ingredient and its mechanism of erectile dysfunction.

This study investigated the antioxidant capacities and inhibitory activity of peeled lotus root (Nelumbo nucifera) as a food material on angiotension-converting enzyme (ACE). The antioxidant effects on total polyphenol and total flavonoid contents were not signicant. However, DPPH radical scavenging activity decreased from 85.07% to 80.70% by peeled treatment. SOD-like activity decreased from 20.84% to 17.97%, and ACE inhibitory activity decreased from 53.4% to 50.1% by peeled treatement. Thus, consumption of non-peeled lotus root should increase.
