  • Adenoid cystic carcinoma (ACC) commonly originates in the major salivary glands and respiratory tract, but it is extremely rare to find ACC in the esophagus. ACC of the esophagus is clinopathologically different from the salivary gland variant. It shows more aggressive malignant behavior and a very poor prognosis. We report here on the surgical and clinopathologic findings of ACC of the esophagus in a 65-year-old man, and we also include a review of the relevant medical literature.

  • Bile salt hydrolase (BSH, EC 3.5.1.24) activity, which cleaves amide bond between carboxyl group (bile acid) and amino group (glycine or taurine), is commonly detected in gut-associated species of human and animal. During the screening of BSH active strains from the fecal samples of elderly human volunteers, strain CU30-2 was isolated on the basis of the highly active BSH producing activity. A bsh gene of the isolate was cloned into the pET22b expression vector and overexpressed in Escherichia coli BL21 (DE3) Gold by induction with 1mM IPTG. The overexpressed BSH enzyme with 6x His-tag was purified with apparent homogeneity using a $Ni^+$-NTA agarose column and characterized. The BSH enzyme of E. faecalis CU30-2 exhibited approximately 50 times higher activity against glycol-conjugated bile salts than tauro-conjugated bile salts having the highest activity against glycocholic acid. Considering the prevalence of E. faecalis strains in the human GI tract and glycol-conjugates dominated bile acid composition of human bile, further study is needed to investigate the impact of the BSH activity exerted by E. faecalis strains to the host as well as to the BSH producing strains.

  • Gamiseunggal-tang(G-tang) has long been used for the treatment of acute and chronic allergic diseases(especially, urticaria) in oriental medicine. But, It's mechanism of action is not well investigated. Anal therapy is another way of taking medicine, which is not used in common situation but available for the treatment of colon and anal diseases. It is also used in GI tract diseases, Gynecological diseases, and pediatric diseases and so on. It is especially benefitable for patients who are in such situations as coma, severe vomiting, and swallowing difficulty. In this study, the author investigated the effects of G-tang by anal therapy on acute and chronic allergic reactions in murine model. The results obtained are as follows: 1. G-tang(0.01, 0.1 g/kg) inhibited the compound 48/80-induced ear swelling response in mice. Inhibitory effects of G-tang was significant (P<0.05) at the dose of 0.01 g/kg. 2. G-tang(0.001-0.1 g/kg) inhibited the cutaneous allergic reaction activated by anti-dinitrophenyl(DNP) IgE in rats. Especially, G-tang 0.01, 0.1 g/kg inhibited the cutaneous allergic reaction significantly. 3. G-tang(0.01-1 g/L) dose-dependently inhibited the compound 48/80-induced histamine release from the peritoneal mast cells. 4. G-tang(0.001-0.1 g/L) had a inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-${\alpha}$ production. Above results indicate that anal therapy of G-tang may be beneficial in the treatment of acute and chronic allergic diseases.

  • Objective : Although chronic non-bacterial prostatitis is a common disease, it is very difficult to treat effectively. GLS (Gleditsiae Spina) has traditionally been used in treatment of urinary tract inflammation and voiding disturbance. In this study, we investigated the therapeutic effects and action mechanism of GLS in the rat model of non-bacterial prostatitis induced by castration and testosterone treatment. Method : We observed four experimental objects of normal group, control group, testosterone group, and GLS group. Rats were treated with 17$\beta$-estradiol after castration for induction of experimental non-bacteral prostatitis, which is similar to human chronic prostatitis in histophatological profiles. GLS and testosterone were administered as an experimental specimen and a positive control, respectively. The prostates were evaluated by histopahological parameters including the epithelial score and epithelio-stromal ratio for glandular damage. Also, the prostates were observed by hematological alterations of WBC, RBC, hemoglobin, hematocrit and platelet. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with GLS showed a diminished range of tissue damage. Epithelial score was improved in GLS over that of the control. The epithelial-stromal ratio was lower in GLS when compared to that of the control. Conclusion : These findings suggest that GLS may protect the glandular epithelial cells. We concluded that GLS could be a useful remedy agent for treating chronic non-bacterial prostatitis.

  • Corrected transposition of the great arteries [C-TGA] is one of the rare congenital heart disease in which there is both a discordant atrioventricular relationship and transposition of the great vessels. With this arrangement, systemic venous blood passes through the right atrium into the morphologic left ventricle and out the pulmonary artery. Pulmonary venous blood returns to the left atrium, flows into the morphologic right ventricle and out the aorta. Thus, in the rare case when no additional cardiac anomaly is present, a hemodynamically normal heart exists. But more often they are symptomatic as a result of one or several of the commonly associated defects. This paper describes 13 patients who underwent repair of one or more cardiac anomalies associated with corrected transposition at SN UH, from June 1976 through June 1984. 1.8 were males and 5 females, with ages ranging from 3 years to 27 years. 2. Segmental anatomy was {S,L,L} in 12, or {I,D,D} in 1. 3.Associated anomalies were ventricular septal defect in 10, pulmonary outflow tract obstruction in 6, tricuspid insufficiency in. 4, atrial septal defect in 3, subaortic stenosis in 1, mitral insufficiency in 1, and patent ductus arteriosus in 1. 4.None had complete heart block preoperatively, and 3 developed complete heart block intraoperatively. But one of them recovered sinus rhythm on the postoperative 7th day spontaneously. 5.There were 3 cases of hospital morality. But there was no morality since Dec. 1980. 6.Patients with single ventricle, hypoplastic ventricle or those who had palliative surgery alone are not included in this review.

  • Microencapsulation of acyclovir, an effective antiviral agent which acts as a specific inhibitor of herpes DNA polymerase, by carbopol-gelatin complex coacervation has been carried out to develop an oral controlled release preparation, which could improve the absorption characteristics in GI tract. After dissolving carbopol and gelatin separately in distilled water at $40^{\circ}C$, gelatin solution was mixed with carbopol solution while stirring at the same temperature. The pH of the mixture was lowered gradually by dropwise addition of 10% HCI with continuous stirring, and then, at pH 3.5, positively charged gelatin molecules were attracted to negatively charged carbopol. These coacervation processes were observed by optical microscopy during preparation. Plasma concentrations of acyclovir in rats after an oral administration of microcapsule suspension were assayed by HPLC, and pharmacokinetic parameters were calculated based on the model-independent analyses. Two standard formulations, oral solution and intravenous bolus injection, were used as references to compare the bioavailability. It has been revealed that $C_{max}$, $T_{max}$, and MRT of microcapsule suspension were greater than those of oral solution, which results in about two-fold increases in bioavailability. Therefore, in conclusion, the carbopol-gelatin microcapsule of acyclovir might be evaluated as an effective oral controlled release preparation which could increase the bioavailability of acyclovir.

  • The purpose of this study was to obtain normative nasalance scores for adult subjects speaking the Korean language. Additional objectives of the study were to determine if speaker sex played a role in differences in nasalance score and there was significantly correlation of nasalance score with nasalance slope score. The subjects include 75 healthy young Korean adults with normal oral and velopharyngeal resource and function. They had no history of speech problem, were judged as having normal speech and resonance at the time of testing, and had no upper respiratory tract infections or allergies at the time of testing. The Nasometer II 6400 was used to obtain nasalance scores and nasalance slope scores for /a/, /i/, /e/, /o/, /u/, /ja/, /je/, /wi/, /p'ap'i/ and /sasi/. The data of nasalance and nasalance slope were analyzed statistically. The mean nasalance score of the female was significantly higher than that of male at /a/, /i/, /wi/, /p'ap'i/ and /sasi/(p <0.10). The mean nasalance score of /i/ was highest and that of /o/ was the lowest. In this study, we could not and the relationship of the nasalance score and the closing slope score. However, there was negative correlation between the mean nasalance score and the opening slope score at ie/ and /;ai, positive to /sasi/. These normative nasalance scores for normal young adults speaking the Korean language provide important reference information for Korean cleft palate teams. In the future study of velopharygneal activity with the Nasometer, the opening slope score will be able to be the important parameter.

  • Colon-specific delivery of glucocorticoids is highly desirable for the efficient treatment of inflammatory bowel disease. We synthesized prednisolone 21-sulfate sodium (PDS) as a colon-specific prodrug of prednisolone (PD) and investigated its properties using rats as test animals. We expected that introduction of sulfate ester as a sodium salt might increase the hydrophilicity and restrict the absorption in the GI tract. If PDS is stable and nonabsorbable in the upper intestine, it will be delivered to the colon as an intact form, where it hydrolyze by the sulfatase to release PD. Compared with PD, the solubility of PDS increased and the apparent partition coefficient decreased greatly. PDS was stable on incubation with pH 1.2 and 6.8 buffer solutions and with the contents of the stomach and small intestine. On incubation with the cecal contents, PDS decreased to 9.6% of the dose in 10 h producing PD. The amount of PD increased to give a maximum 54% of the dose and decreased. As a control, when PD was incubated with the cecal contents, it decreased to 29% of the dose in 8 h, which implied that reduction of PD proceeded under such conditions. These results suggested that hydrolysis of PDS took place to produce and accumulate PD, which decreased by reduction as the incubation period extended. Our results suggested that PDS can be a promising colon-specific prodrug of PD, and sulfate ester group might serve as a potential colon-specific promoiety, especially for the drugs which are resistant to reduction in the colon.

  • Embryo transfer (ET) technology is of high importance in modern cattle breeding programs. ET is one step in the process of removing one or more embryos from the reproductive tract of an outstanding donor female and transferring them to one or more recipient females. Embryos also can be produced in the laboratory via techniques such as in vitro fertilization (IVF). But the actual transfer of an embryo is only one step in a series of processes that may include some or all of the following: superovulation and insemination of donors, collection of embryos, isolation, evaluation and short-term storage of embryos, micromanipulation and genetic testing of embryos, freezing of embryos and embryo transfer. Cryopreservation and direct transfer of frozen-thawed embryos is common-place with pregnancy rates near that of fresh embryos. Polymerase chain reaction (PCR) technology is currently being used for sexing embryos, and this technology will be used for "embryo diagnostics" and "embryo genomics" in the future. Although, many limitations and problems remain to overcome, these and other new technologies promise to change livestock breeding drastically in the next decade.

  • The use of lactic-acid bacteria (LAB) is effective for preventing and curing immune disorders by activating the immune system in the digestive tract and the consequent immune response in the blood. In this study, LAB and mixed LABs were used in an atopic dermatitis (AD) mouse model. Alleviation of AD was observed based on the change in cytokine level and immunohistochemical staining. An ex vivo test showed that immunoglobulin-E and interleukin (IL)-4 levels were significantly lower in all groups treated with LAB than in the group treated with only 1-chloro-2,4-dinitrobenzene. Results of an in vivo test based on the ex vivo results showed that the scratch score decreased in all groups treated with the LAB and particularly decreased in the group treated with mixed LABs. Additionally, the T helper (Th) 1 cytokines interferon-gamma and IL-12p40 were upregulated by the LAB and mixed-LABs, whereas levels of the Th2 cytokine IL-4 were downregulated in a mouse model of AD-like skin lesions. Furthermore, hematoxylin & eosin and immunohistochemical staining of the dorsal area of the mice in each group showed that AD improved in the LAB-treated groups. These results suggest that LAB and mixed LABs inhibit the development of AD in NC/Nga mice by suppressing the Th2 cell response and increasing the Th1 cell response. Our results indicate that mixed LABs are better than LAB for treating AD-like skin lesions.
