Acute transverse myelitis (TM) is a neurological syndrome caused by inflammation of the spinal cord. TM is rare but is frequently caused by viral or bacterial infections. TM caused by tuberculosis (TB) is extremely rare and there are no reports of TM caused by multidrug-resistant TB (MDR-TB). We report a case of acute TM due to MDR-TB in a 40-year-old man. The patient had been diagnosed with pulmonary TB and was started on the first-line anti-TB treatment. However, the chest radiographic findings were aggravated and neurological symptoms such as weakness in both lower extremities, sensory changes, and voiding difficulty were newly developed. The T2-weighted magnetic resonance image of the spine showed diffusely increased signal intensity in the spinal cord, particularly at the lower cervical and upper thoracic levels, without any definite evidence of myeloradicular compression, which is consistent with a diagnosis of TM. A drug susceptibility test revealed MDR and second-line anti-TB drugs were prescribed. The chest radiographic findings showed improvement after treatment, the mycobacterial culture converted to negative, the MRI findings improved, and there was partial improvement in the low extremity weakness. The patient has been prescribing second-line anti-TB medications for 14 months.

A 55-year-old woman was admitted for an elevated serum carbohydrate antigen-125 (CA-125) level, and a left pleural effusion, which were detected at a routine health examination. Computed tomography of the chest was performed upon admission, revealing extensive bilateral paratracheal and mediastinal lymph node enlargement with a massive left-sided pleural effusion. Subsequent analysis of the pleural fluid demonstrated consistency with an exudate, no evidence of malignant cells, and a normal adenosine deaminase. However, the pleural fluid and serum CA-125 levels were 2,846.8 U/mL and 229.5 U/mL, respectively. A positron emission tomography did not reveal any primary focus of malignancy. Finally, a surgical mediastinoscopic biopsy of several mediastinal lymph nodes was performed, revealing non-necrotizing granulomas, consistent with sarcoidosis. After a month of treatment of prednisolone, the left pleural effusion had resolved, and after 2 months the serum CA-125 level was normalized.

Although reports of multiple primary malignant tumors have increased recently, cases of synchronous double primary tumors of lung and liver are rare. A 73-year-old man suffered from chronic cough. His chest x-ray showed segmental atelectasis of the right upper lobe. Bronchoscopy revealed a mass occluding the orifice of the anterior segmental bronchus of the right upper lobe, and a biopsy showed a squamous cell carcinoma. A synchronous hepatic mass was found by ultrasonography. However, F18-FDG-PET showed no evidence of a distant metastasis. The liver biopsy revealed a hepatocellular carcinoma. A right upper lobe lobectomy and a sleeve resection were performed for the lung cancer, and radiofrequency ablation was performed for the hepatocellular carcinoma.

Purpose: Previously reported ocular complications of interferon alfa administration are extremely rare. We experienced a 15-year-old boy with chronic hepatitis B who developed glaucoma after interferon alfa therapy. The purpose of this prospective study was to evaluate the possible development of glaucoma after interferon alfa therapy for chronic hepatitis B. Methods: Nine patients with chronic hepatitis B who visited Inha university hospital between February 1998 and July 1999 received interferon alfa therapy. We measured visual acuity, intraocular pressure, C/D ratio, and visual field examination at pre-interferon therapy, three and six months after therapy, respectively. Results: The total number of patients was 9 (4 boys and 5 girls). Mean age was $11.7{\pm}4.1$ years. The duration of therapy was 6 months and mean dosage of interferon was 5 million units. Compared with visual acuity, intraocular pressure, and C/D ratio at pre-therapy, those parameters at 3 months and 6 months after therapy showed no significant differences and none showed visual field defect after therapy. Conclusion: Our prospective study showed no evidence of development of glaucoma after interferon therapy. However, it is necessary to be concerned about the possibility of developing glaucoma or other ophthalmologic diseases after interferon therapy in chronic hepatitis B.

Objective: The purpose of this study was to examine the effect of the Spaced Retrieval Training (SRT) with Errorless learning on the elderly with Mild Cognitive Impairment (MCI)'s memory, Instrumental Activities Daily Living, Depression symptom. Methods: A single subject experimental research with ABA design was conducted in this study on the 78-years-old person who was enrolled in day-care center. The total experimental sessions were 16 which composed of 3 sessions for baseline, 10 sessions for intervention and 3 sessions for second baseline. K-Auditory Verbal Learning Test (K-AVLT) was measured for the memory each session. For the measurement of cognitive function, IADL, depression Symptom, Korean version of Montreal Cognitive Assessment (MoCA-K), Philadelphia Geriatric Center Instrumental Activities Daily Living (PGC IADL), Geriatric Depression Scale Korean Version (GDS-K) was measured at pre-post test. Results: Memory at the phase B was improved than Phase A. At the phase B, the scores trend was ascending, but after the intervention at the phase A', the scores trend was descending. The scores of MoCA-K were improved, PGC IADL were maintained, GDS-K were decreased. Conclusion: This results support the evidence of the SRT with EL on the elderly with MCI in the clinical setting. In the future, the correlation researches about MCI's memory and other functional factors will be needed for effective occupational therapy service.

The objectives of this study were to examine the changes of birth weight and relationship of birth weight with maternal age and parity. The study population included 13,634 single live births out of 14,346 births delivered at a general hospital in Busan between January 1, 1977 and December 31, 1956. Data were obtained from the delivery record. In 1979 the mean birth weight of male was 3,074 gm and that of female was 2,985 gm. In 1986 birth weight of male was increased to 3,266 gm and that of female to 3,210 gm. Low birth weight ($\leq$2,500 gm) incidence rate was 7.2% in 1977 and it was increased gradually to 10.4% in 1980 but decreased thereafter to 6.5% in 1986. Incidence rate of overweight infant (4,001 gm $\leq$) was 3.9% for 10 years and it ranged from 2.9% to 4.6% but no particular changing pattern was observed. The percentage of mothers who had history of induced abortion was decreased from 51.6% in 1979 to 45.1% in 1986. Also, stillbirth rate was decreased from 2.6% in 1977 to 1.5% in 1986. The proportion of the first and second births was increased from 55.4% in 1977 to 96.0% in 1986 and the proportion of mothers of 25-34 years increased from 72.1% in 1977 to 84.7% in 1986. The incidence rates of low birth weight and over weight infant are lower in the first and second births of 25-34 years old mothers than other parities and age groups. Increased mean birth weight and decreased low birht weight incidence rate indicate that the health status of newborn infants has been improved and substantial portion of these changes can be attributed to increase in family planning practice rate and delayed marriage. There is no evidence, however, for increasing incidence rate of overweight infant.

Extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) is usually indolent. Although it was reported recently that about 20-30% cases of MALT lymphoma presented with a disseminated disease at diagnosis, it was described as a disease localized at diagnosis and remaining stable for a prolonged period. However, only a few cases of MALT lymphoma involved the lung and gastrointestinal tract all at once. We report a case of a 73-year-old man with disseminated MALT lymphoma. He presented with non-productive cough, initial chest radiograph showed a nodule in the right lower lobe. The diagnosis of stage IV MALT lymphoma was made by CT scan, video-assisted thoracoscopic excisional biopy, gastrofiberscopic biopsy and bone marrow biopsy. The lymphoma involved the lung, stomach and bone marrow at the time of diagnosis. Because he refused chemotherapy, he discharged after Helicobacter pylori eradication without chemotherapy. Regular follow-up examination did not show any evidence of disease progression over 22 months.

Signet ring cell carcinoma of lung is an unique variant of mucin producing adenocarcinoma which is characterized by abundant intracellular mucin accumulation. Only a few cases of primary signet ring cell carcinoma of lung have been reported in the world wide literature. And we have, recently experienced one case of primary signet ring cell carcinoma of lung. A 55 years old man was evaluated for paralysis of lower extremities and was found to have lung cancer in the left upper and lower lobe with pleural, multiple spinal, bone and liver metastases. Signet ring tumor cells were revealed by cytologic examination of pleural fluids. And there were no evidence of signet ring cell carcinoma of other organs. Primary signet ring cell carcinoma of lung seems to have an aggressive behavior and therapeutic modalities could be different from those for signet ring cell carcinomas from other organs. Therefore it is important to separate primary signet ring cell adenocarcinoma of lung from metastatic tumors.

Gastric carcinoid tumor is a neoplasm that arises from enterochromaffine-like (ECL) cells in the gastric fundus. It is a rare disease that comprises less than 2% of all gastric neoplasms; however its incidence has been recently increasing. We experienced one case of gastric carcinoid tumor that was revealed to be multiple polypoid lesions. A 29-year-old female patient visited a hospital three years ago due to syncope. The blood hemoglobin was measured as 6.0 g/dl. Gastroscopy revealed multiple polypoid lesions with bleeding; therefore endoscopic clipping was performed. The polyps were diagnosed as carcinoid tumor via endoscopic biopsy. She was transferred to our hospital because of persistent iron deficiency anemia that was caused by bleeding at the gastric polyps. Gastroscopy revealed more than twenty various-sized polypoid lesions from the mid-body to the antrum. The blood hemoglobin level was 9.0g/dl. Total gastrectomy was performed under the diagnosis of gastric carcinoid tumor with bleeding. All of the gastric polyps were diagnosed as carcinoid tumors, and any metastasis to the regional lymph nodes was not found. Eighteen months after operation, the blood hemoglobin was increased to 12.8g/dl with no evidence of recurrence. Surgical resection should be considered for treating gastric carcinoid tumor with continuous bleeding.

Three lines of White Leghorn (WL) chickens (IWJ, IWG and IWC) maintained at Central Avian Research Institute, Izatnagar (UP), were used for chorioallantoic membrane (CAM) and liver tumour (LT) assay. Eleven-day-old embryos of each line were partitioned into three groups and inoculated with 0.2 ml of subgroup A, subgroup C and an equal mixture of subgroup A and C Rous sarcoma virus (RSV). Subgroup virus receptor on the cell surface membrane for subgroup A is coded for by tumour virus a (tva) locus and for subgroup C by tumour virus c (tvc) locus. The random association of the genes at the tva and tvc loci in IWJ and IWC line was assessed and the $x^2$-values for phenotypic classes were found to be significant, indicating the linkage between the tva and tvc loci. The linkage value was estimated to be 0.09 on pooled sex and pooled line basis. On the basis of four subclass tumour phenotypes a 4-allele model was proposed for tva locus having $a^{s1}$, $a^{s2}$, $a^{r1}$ and $a^{r2}$ alleles and the frequencies were calculated as 0.47, 0.13, 0.13 and 0.27 for IWJ line, 0.31, 0.33, 0.14 and 0.22 for IWG line and 0.44, 0.11, 0.21 and 0.24 for IWC line, respectively. Similarly, for tvc locus the frequencies of four alleles i.e. $c^{s1}$, $c^{s2}$, $c^{r1}$ and $c^{r2}$ were calculated as 0.42, 0.20, 0.21 and 0.17 for IWJ line, 0.42, 0.17, 0.27 and 0.14 for IWG line and 0.30, 0.21, 0.16 and 0.33 for IWC line, respectively. The $x^2$-values for all classes of observations were not significant (p>0.05), indicating a good fit to the 4-allele model for the occurrence of 4-subclass tumour phenotypes for tva and tvc loci. On the basis of the 2-allele model both tva and tvc locus carries three genotypes each. But, on the basis of the 4-allele model tva and tvc locus carries 10 genotypes each. The interaction between A-resistance and C-resistance (both CAM and LT death) was ascertained by taking the 10 genotypes of tva locus and 3 genotypes of tvc locus by pooling the lines and partitioning the observations into 3 classes. The $x^2$-values for the genotypic classes of CAM (-) LT (+) and CAM (-) LT (-) phenotypes to mixed virus (A+C) infection were found to be highly significant (p<0.01), indicating increased resistance, which indicates the joint segregation of $a^r$ and $c^r$ genes, suggesting the existence of close linkage between the tva and tvc loci. Therefore, an indirect selection approach using subgroup C viruses can be employed to generate stocks resistant to subgroup A LLV, obviating contamination with the most common agent causing LL in field condition.
