The majority of chronic gingival ulcerative lesions are known to be due to autoimmune disease such as oral lichen planus, benign mucous membrane pemphigoid or pemphigus vulgaris. Topical or systemic corticosteroids are mainly used and adjuvant drugs like immunosuppressant, anti-inflammatory drugs, antimalarials or antimetabolites can also be prescribed. Because systemic corticosteroids causes various side effects, such as gastrointestinal disturbance, osteoporosis, diabetes or adrenal suppression. So, topical steroid therapy is main treatment for chronic gingival ulcerative lesion confined to small area. However, there's also limitation of topical corticosteroids. The effect of the corticosteroids decreases due to salivary flow and the movement of the tongue, lips, or buccal mucosa. When the lesions are widely distributed or positioned deeply in oral cavity, it is hard to apply the medication on patients' own. Moreover, it can be applied to unaffected mucosa. Although occlusive steroid therapy using stent was reported to minimize taking steroid and overcome the faults of applying topical steroids, it has been used less frequently in the clinical field. Therefore, this report is going to find out the usefulness and the way to utilize clinically through the case which acted satisfactorily by performing topical steroid therapy using stent on chronic ulcerative gingival lesions.

Arsenic trioxide($As_2O_3$) was introduced into the treatment of refractory or relapsed acute promyelocytic Ieukemia. Some investigators have reported that arsenic trioxide had induced apoptosis in a variety of solid human tumor cell lines, including non-small cell lung cancer. Non-steroidal anti-inflammatory drugs(NSAIDs) are powerful chemopreventive agents for gastrointestinal cancers and the growth of established tumors are reduced by inducing apoptosis. It's also reported that NSAIDs enhanced tumor response to chemotherapeutic drugs or radiation. In this study, we aimed to determine whether combination of arsenic trioxide with sulindac augmented its apoptotic potential in NCI-H157 human lung cancer cells. The human lung cancer cell line NCI-H157 was treated with arsenic trioxide and sulindac. Cell viability was measured by the MTT assay. Apoptosis was measured by nuclear staining and flow cytometric analysis. The catalytic activity of the caspase families were measured by the fluorogenic cleavage of biosubstrates. The western blotting were also performed to define the mechanical basis of apoptosis. Combination treatment of arsenic trioxide and sulindac decreased the viability of NCI-H157 human lung cancer cells in a dose-dependent manner. The catalytic activity of caspase-3, 8 and 9 proteases were increased after combination treatment. Consistently PARP was cleaved from 116kDa to 85kDa fragments, and the expression of ICAD was decreased by time-dependent manner. Also combination treatment increased the expression of Fas and Fas/L. Combination therapy of arsenic trioxide with sulindac augments cell death and induces apoptosis via the activation of caspase cascade in NCI-H157 human lung carcinoma cells.

Objective: In the early short-term therapy of pulmonary tuberculosis, PZA is used for the first two months on 6EHRZ therapy but PZA is not effective in the case of long-tenn use PZA for retreatment in the sensitive relapse or acquired drug resistance for PZA. But in the endemic area as Korea, if we can't use PZA in the retreatment of pulmonary tuberculosis, we can't expect the success for retreatment of pulmonary tuberculosis, therefore we need new drugs substituting for PZA. In these days, 4 - fluoroquinolone derivatives were investigated and only ofloxacin and ciprofloxacin of derivatives were known to be effective but the effectiveness was also not certain because the result was experimental or combined with other bacteriocidal drugs and datas on effectiveness of pulmonary tuberculosis were so little. Therefore these drugs should be use with other two or three strong-acting drugs in the last period of retreatment of pulmonary tuberculosis. The ofloxacin or ciprofloxacin is used in some area in Korea but randomly and needed more study. We did this study for proving the effectiveness of these drugs and establishment of retreatment regimen for pulmonary tuberculosis. Methods: Retrospective cohort study of 83 drug-resistant pulmonary tuberculosis patients at National Masan Tuberculosis Hospital from Jan. 1994 to dec. 1995 was made. All the patients taken medicine for 2nd ami-tuberculosis regimens for the first lime. We separated the patients by two groups.(Group I : OFX+ PTA + CS+PAS + Injection, Group II: PZA + PTA+ CS + PAS + Injection). We compared the difference between two groups and tested the confidence limit about results after treatment by $\chi$2-test and T-test. Results : 1. The age distribution was most frequent in fourth decade(29.2% in Group I, 37.1% in Group II) and the mean age was 43.9 year in Group I, and 39.0 year in Group II, but had no significant difference between two groups. The sex distribution was more frequent in the males(68.8% in Group I, 85.7% in Group II), but had no significant difference. 2. Family history was 29.2% in Group I, 28.6% in Group II, but had no significant difference. 3. In the respect of extent of disease, far-advanced stare was 60.4% in Group I, 74.3% in Group II, but had no significant difference. 4. The side effects for drugs showed in 58.3% in Group I and 65.7% in Group II, and the gastrointestinal trouble showed 25.0% in Group and arthralgia 34.3% in Group II predominantly respectively and had the significant difference(p<0.05). 5. The negative conversion rate on sputum AFB smear was 87.5% in Group I and 80.0% in Group II, but had no significant difference. But the negative conversion rate on sputum AFB culture was 83.3% in Group I and 57.1 % in Group II and had the significant difference(p<0.05). 6. The success rate of treatment was 87.5 % in Group I and 83.3 % in Group II but had no significant difference. Conclusion : In the retreatment of pulmonary tuberculosis, ofloxacin is useful drug for the patients who are not available to use PZA and can be use effectively substituting for PZA.

This case show that emotional stress and wekness of gastrointestinal function occur a chronic hiccup and eructation(during 3 months), oriental medical therapy can cure completely this symptom. Seven emotional stress(anger, delight, sadness, thinking, worry, fear, horror) occur various pathologic changes. Hiccup is caused by CNS, psychologic, thoracic, abdominal factor etc. In oriental medicine, GI trouble regarded as a very importent factor that occur hiccup and eructation. Besides, emotional stress is a very important factor as well. This patient have an introvert personality ordinary times. One day, she had a miscarriage by hers husband's assault. After that time, she suffered from very serious GI trouble(dyspepsia, epigastric pain, anorexia). And then hiccup, eructation, weight loss(10kg/3months) is occured. This patient diagnosed only gastritis. This symptom did not stop during 3 months, regardless of western medical therapy(some western drugs medication, fluid supply etc). After oriental medical therapy(herb medicine;Yukunjatang, acupuncture;CV12, CV6, S36, CV17, H7, SP6, P6, moxibustion;VI2, CV6, S36, negative therapy;back area and traditional oriental medical psychotherapy;ventilation, support, desensitization and family interview) put in operation during 15 days, patient completely recover from hiccup, eructation and anxiety disorders.

The use of nonsteroidal anti-inflammatory drugs (NSAIDs) is limited by their ability to induce gastrointestinal injury. It has been shown that nitric oxide (NO), similar to pro staglandins (PGs), appears to play an important role in gastric mucosal defence. We hypothesized that NSAIDs contained NO group would be less acutely toxic to the gastric mucosa, but would not interfere with their ability to suppress inflammatory process in rats. We have compared the ulcerogenic and anti-inflammatory effect of CW-501029 (NO-NSAIDs), CW-501027 (NSAIDs) and indomethacin. Both did not change mean blood pressure and heart rates, indicating that they had no side effect on cardiovascular system. We found that CW-501029 increased nitrite/nitrate levels without changing of blood pressure and heart rates. We suggest that it may help gastric mucosal blood flow, the which helps reducing the discomfort in astrointestinal system. Carrageenan-induced PGE2 increase was reduced in a similar tendency when compared CW-501027 or CW-501027 with control in back exudate of rats, but CW-501029 less reduced PGE2 than CW-502027 or indomethacin in gastric tissues. CW-501027 or CW-501029 reduced platelet aggregation. From these results we suggest that CW-501029 may improve the side effect by reduction of short-term gastric injury and less inhibition of PGs synthesis.

Background: Panax ginseng is a well-known immune modulator, and there is concern that its immune-enhancing effects may negatively affect patients with rheumatoid arthritis (RA) by worsening symptoms or increasing the risk of adverse effects from other drugs. In this randomized, crossover clinical trial, we evaluated the impact of Korean Red Ginseng (KRG) on disease activity and safety in RA patients. Methods: A total of 80 female RA patients were randomly assigned to either the KRG (2 g/d, n = 40) treatment or placebo (n = 40) groups for 8 wk, followed by crossover to the other treatment group for an additional 8 wk. The primary outcome was the disease flare rate, defined as worsening disease activity according to the disease activity score 28 joints-erythrocyte sedimentation rate (DAS28-ESR). The secondary outcomes were development of adverse events (AEs) and patient reported outcomes. Outcomes were evaluated at baseline and 8 wk and 16 wk. The outcomes were compared using the Chi-square test. Results: Of the 80 patients, 70 completed the full study. Their mean age was 51.9 yr, and most exhibited low disease activity (mean DAS28-ESR $3.5{\pm}1.0$) at enrollment. After intervention, the flare rate was 3.7% in each group. During KRG treatment, 10 AEs were reported, while five AEs were developed with placebo; however, this difference was not statistically significant (p = 0.16). Gastrointestinal- and nervous system-related symptoms were frequent in the KRG group. Conclusion: KRG is not significantly associated with either disease flare rate or the rate of AE development in RA patients.

After the advent of the effective antimicrobial drugs, empyema of the pleural cavity came to be considered an infrequent disease. However, in recent years the problem of empyema is increasing, probably due to bacterial changes associated with the use and misuse of antimicrobials as well as alterations in the host associated with increased longevity and chronic disease. During the 10 years period from 1957, Sop. to 1977, Aug., we experienced 152 cases of empyema, of which 37 were scheduled on open thoracotomy drainge for chronic empyema. 1. The ratio of male to female was 3.6:1 with male predominance and 64% of total was above 40 years old in age distribution. 2. The cardinal symptoms were fever[70%], dyspnea[40.5%], and sputum[40.5%]. The leucocytosis were observed in 75.7% of all cases. The hemoglobin level showed subnormal in 21.6% of all cases. 3- The underlying pathology predisposing to empyema were postoperative empyema [35.1%] and tuberculosis[32.4%] in order. 4. The pathologic organisms by bacterial culture in 37 patients were Pseudomonas [24.3%], Staphylococccus [21.6%], Streptococcus [21.6%]., no growth [8. 1%] and the remainders. 5. The late results were as follow; a. Spontaneous closure was seen in 10 patients and all of them belongs to non-tuberculous group. Their mean duration was 14 months. b. Still opened are eight; 6 in tuberculous group, remainders in non-tuberculous group. c. Secondary closure was performed in 6 patients, of which 5 cases showed successful secondary closure but one failed. The mean duration from OTD to secondary closure was 46.3 days. d. Eleven patients were not followed. e. Two patients were expired; one was due to progressive cachexia and pulmonary insufficiency, the other due to gastrointestinal bleeding unrelated to empyema.

This research was to find out the protective and healing effects of both the Jiguyangwi-tang and the Gamijiguyangwi-tang on the gastric mucosa injuries by cyclophosphamide. At first, Jiguyangwi-tang and Gamijiguyangwi-tang extract were administered to the mice before one week, and then integral administration of those two drugs(each herbal extract and cyclophosphamide) were followed for another one week, respectively. After finishing those treatments, I have examined the state of the both ulcer and inflammation on the damaged gastric mucosa cell and watched the level of proliferating cell nuclear antigen(PCNA), Bcl-2, and apoptosis. These results were as follows, 1. Gastric mucosa inflammation have more significantly reduced in groups of integral administration of Jiguyangwi-tang plus cyclophosphamide, Gamijiguyangwi-tang plus cyclophosphamide and cyclophosphamide then in group of single cyclophosphamide. 2. Gastric ulcer have been reduced in groups of integral administration of Jiguyangwi-tang plus cyclophosphamide, Gamijiguyangwi-tang plus cyclophosphamide and cyclophosphamide then in group of single cyclophosphamide. But the significance have not shown. 3. PCNA level have more significantly elevated in integral administration of Jiguyangwi-tang plus cyclophosphamide and Gamijiguyangwi-tang plus cyclophosphamide and cyclophosphamide then in group of single cyclophosphamide. 4. The significance of both apoptosis induction and bcl-2level have not noticed among all groups. 5. Between Jiguyangwi-tang and Gamijiguyangwi-tang, the differance of effect was not admitted in statistically From these results, it is suggested that Jiguyangwi-tang and Gamijiguyangwi-tang are useful medicines in protecting gastric inflammation and ulcer, that is gastrointestinal side-effect of cyclophosphamide. The preventing effect of Jiguyangwi-tang and Gamijiguyangwi-tang may be through the 'affecting the period of cell division', but not the inhibition of apoptosis.

Mosapride stimulated dietary motility was introduced because of the arrhythmogenic effect of cisapride. Cisapride, 5-HT receptor agonist, induces prolongation of QT interval. Additionally, this condition can raise the possibility of acute, "malignant" arrhythmias such as torsade de pointes. It is hard to find any reports about effects of mosapride on cardiac parameters in dogs. By confirming electrocardiogram (ECG) parameters, the surface extremity leads ECG that was obtained from the four-limb electrodes and which was recorded by an ECG recorder after administration of mosapride 3 mg/kg PO b.i.d, and mosapride 3 mg/kg with itraconazole 5 mg/kg PO b.i.d, respectively. QT interval was shortened on the days of 3, 5, and post-day 1 in both mosapride 3 mg/kg administrated group and mosapride with itraconazole group. Heart rate increased significantly. QTc was slightly prolonged in mosapride administration group and mosapride with itraconazole group. However, all dogs of QTc were in normal variation (150~250 msec). Besides, the dogs showed no side effects reported in human medicine during the administration with these drugs. Although mosapride can increase the heart rate, this study suggest that mosapride may be useful for the dogs with disorders of gastrointestinal motility because of no fatal arrhythmogenic effect inspite of administration with itraconazole in dogs.

Applications of liposomes as a drug carrier for the oral delivery of poorly-absorbable macromolecular drugs have been limited, because of their instability in gastrointestinal environments including pH, bile salts, and digestive enzymes. Two polysaccharides, dextran(DX) and pullulan(PL), were introduced to the preformed liposomes in order to enhance the stability. Palmitoyl derivatives of polysaccharides, palmitoyldextran(PalDX) and palmitoylpullulan(PalPL), were synthesizd and introduced to the liposomes during preparation for the same purpose of stability. The effects of these polysaccharides coating were evaluated basically by physical properties of particle size distribution and optical microscopy, then compared with uncoated liposomes by the observations of both in vitro stability and in vovo absorption characteristics. The geometric mean diameters of polysaccharide-coated liposomes were greater than that of uncoated liposome, showing the outermost polysaccharide-coated layer under the optical microscopy. In vitro stabilities of uncoated or polysaccharides-coated liposomes were measured by turbidity changes in various pH buffer solutions containing sodium choleate as bile salts. While uncoated liposome was very sensitive to bile salts, polysaccharides-coated liposomes were stable in relatively higher concentrations of sodium choleate, giving the results of better stability of PalDX- and PalPL-coated liposomes than that of DX- and PL-coated liposomes. After liposomal encapsulation of acyclovir(ACV), an antiviral agent as a model drug, it has been administered orally to rats as dose of ACV 40 mg/kg. Plasma concentrations of ACV were assayed by HPLC and analyzed by model-independent pharmacokinetics. Pharmacokinetic parameters of Cmax, tmax, and [AUC] have been compared.
