AIM: To study the chemical constituents and their anti-amnesic effect from the hooks of Uncaria rhynchophylla. METHODS: The isolation of compounds was performed by chromatographic techniques and their structures were identified on the basis of spectral analysis. Their ameliorating effects on scopolamine-induced memory impairment in vivo using a Morris water-maze task and passive avoidance task system were evaluated. RESULTS: Activity-guided fractionation of the total extracts resulted in the isolation of four constituents, trans-anethole (1), p-anisaldehyde (2), estragole (3), and 3-oxo-olean-12-en-28-oic acid (4), which were found for the first time from this plant. CONCLUSION Compound 1 exhibited a better memory enhancing effect than tacrine, a positive agent, at the same dose in the passive avoidance test and a similar property in the water-maze test, and its action may be mediated, in part, by the acetylcholine enhancing cholinergic nervous system.

PURPOSE: To improve low sensitivity of urinary cytology in diagnosis and surveillance of bladder cancer, we performed a study using the Lewis X immunocytology with the murine BG-7 monoclonal anti-Lewis X immunoglobulin M antibody while comparing it with conventional urinary cytology. MATERIALS AND METHODS: Barbotage bladder washings were performed in 36 patients who were diagnosed as having bladder tumor after cystoscopy. The specimens were divided into conventional urinary cytology and immunocytochemical examinations. The cytologic examination was done according to Papanicolau. Indirect immunoperoxidase staining of urine samples was done using the murine BG-7 monoclonal antibody against the Lewis X antigen. Biopsies were obtained in all cases via transurethral resection. The results were analysed according to the tumor stage and grade. RESULTS: Of the 36 patients, 33 patients were diagnosed with transitional cell carcinoma, 1 with inverted papilloma, and 2 with chronic inflammation. Immunocytology showed positive results in 25 of the 33 patients, corresponding to a sensitivity of 75.8% while conventional cytology showed a sensitivity of 45.5%. This discrepancy was vivid in the cases of low grade transitional cell carcinoma. The sensitivities of conventional cytology were 23% in grade I and 50% in grade II, while those of immunocytology were 50% in grade I and 100% in grade II. CONCLUSIONS: Our data show that Lewis X immunocytology using the murine BG-7 monoclonal anti-Lewis X antibody can improve the sensitivity of noninvasive detection of transitional cell carcinoma of the bladder, especially in low grade tumor.

Hydrogen peroxide solution is commonly used for irrigating and cleaning wounds. When it is applied to tissues, catalase causes its rapid molecular degeneration with the release of oxygen bubbles. We present case report illustrating two hazards ; chemical colitis and oxygen embolus. A 29-year-old previously healthy woman presented to the bloody diarrhea and anal pain after hydrogen peroxide enema. In the colonoscopic examination, severe mucosal edema and ulceration with bleeding was noted from anus to sigmoid colon. With use of anal endosonography, multiple high level echo were noted in the internal and external anal sphincter of the upper anal canal. Microscopically, mononuclear cells were infiltrated in lamina propria and congestion. She had treatment with IV fluid, IV antibiotics and NPO. At 3rd hospital day, anal pain was disappeared. Bloody stool was disappeared next day. At 8th hospital day, mucosal edema and ulceration were disappeared on colonoscopic examination. Recovery was full and the patient was discharged at nine days after the episode.

OBJECTIVE: Clozapine is known as an atypical antipsychotic drug which has less side effects in the extrapyramidal system than typical antipsychotic drugs and recommended as a treatment of choice in severe tardive dyskinesia (TD). However, it has been reported that the existing TD was worsened or new TD appeared in some cases where the antipsychotic drugs were switched to clozapine. METHODS: We experienced a single case in which TD was appeared in the tongue and jaw 5 months after chlorpromazine was switched to clozapine. RESULTS: The subject was 57 years old male patient with bipolar disorder. He had been treated intermittently with lithium and chlorpromazine for over 30 years. Five months after switching from chlorpromazine to clozapine, TD appeared in the tongue and jaw. Using Extrapyramidal Symptom Rating Scale (ESRS), the dyskinesia score was 10. Hence, clozapine was stopped and chlorpromazine was re-administrated resulting gradual improvement of TD. The dyskinesia score of ESRS was dropped to 6. CONCLUSION: It is speculated that this case is most likely a withdrawal tardive dyskinesia but other possibilities should be considered too. The question "Does withdrawal tardive dyskinesia occur more easily when switched to clozapine which has a weak dopamine antagonism?" should be addressed in future study.

OBJECTIVES: The purpose of this study was to evaluate the psychometric properties of the Korean version of the Readiness to Change Questionnaire-Treatment version (RCQTV-K). METHODS: The participants were 92 patients who were seeking treatment of alcoholism in two hospitals for alcoholism. A confirmatory factor analysis was performed to test whether the factor structure of the RCQTV-K was consistent with the English version. Convergent validity was assessed by correlating the scores on the RCQTV-K with those on other scales (Alcohol Abstinence Self-Efficacy Scale, Beck Depression Inventory, Korean Version of Alcohol Use Disorders Identification Test). RESULTS: The factor structure of the RCQTV-K was consistent with the three-factor structure established for the original RCQTV. Cronbach's alpha was high, indicating that the reliability of the items for each subscale was satisfactory. Allocated stage of change showed significant differences among the scores on the other scales. CONCLUSION: The results of the present study indicate that the RCQTV-K is an effective and valid scale for evaluating the stage of readiness to change in patients seeking treatment for alcoholism. The findings suggest that the RCQTV-K is a promising assessment tool for use in the treatment and study of alcoholism.

BACKGROUND AND OBJECTIVES: The aim of the study was to evaluate the difference of temporal lability in myocardial repolarization between acute non-Q (NQMI) and Q-wave myocardial infarction (QMI), and to discern whether the locations of myocardial infarction influence such temporal lability. SUBJECTS AND METHODS: Twelve patients with NQMI and 28 with QMI, including 16 anterior (AMI) and 12 inferior MI (IMI) patients were enrolled. Twenty four-hour ambulatory ECG recordings of each patient were analyzed, and the digitized data was partitioned into 30-min sections. The QT intervals were measured using a template matching strategy. We then calculated the low (LF:0.03 - 0.15 Hz) and high frequency (HF:0.15 - 0.4 Hz) power of the QT interval variability using an algorithm capable of removing the influence of the RR-interval on QT interval variability (Normalized Idioventricular QT variability Index:IV-QT). RESULTS: For patients with QMI, the low frequency IV QT (LF IV-QT) was higher than that of NQMI (1.941+/-0.101 and 1.556+/-0.114 respectively, p<0.05). No difference was seen in the high frequency IV QT (HF IV-QT) of the two groups. For QMI patients, both the LF IV-QT and HF IV-QT were higher in day time (6AM-6PM) than in night time (6PM-6AM). Comparing the differences of these indices by the location of QMI, both the LF IV-QT and HF IV-QT of AMI were higher than those of IMI patients (2.231+/-0.135 vs 1.355+/-0.131 and 2.341+/-0.161 vs 1.346+/-0.145 respectively, p<0.0005). Both indices of each group also demonstrated a circadian change. CONCLUSION: In cases of QMI, the temporal lability in myocardial repolarization is larger than that seen in NQMI. Moreover, it was worse in AMI than IMI. Finally, such temporal repolarization lability tends to have a circadian pattern in QMI.

Kaposi's sarcoma, a rare tumor, usually presents itself with skin lesions. However, extracutaneous lesions are common and the gastrointestinal tract is often involved. Gastric Kaposi's sarcoma is usually asymptomatic, but may cause massive gastrointestinal hemorrhage, perforation, intestinal obstruction, intussusception, protein-losing enteropathy, or sepsis. The gastroscopic appearances of Kaposi's sarcoma range from reddish purple maculopapules to polypoid, umbilicated nodules. In Korea, only one case of gastric Kaposi's sarcoma had been reported until now. A case of gastric Kaposi's sarcoma treated with VP-16 (etoposide) is here in reported with the endoscopic findings before and after chemotherapy.
