Korean Journal of Dermatology 1977;15(2):211-215
Acrokeratosis verruciformis is a familial disease characterized by indolent papules resembIing flat warts on the backs of the hands and feet with lesser involvement of volar surfaces, wrists, and ankles. A cas of 42 years old female with acrokeratosis verruciformis is reported. The skin lesions of this patient showed numerous rice to pea sized, flat-topped, round or polygonal, warty papules on the dorsal aspects of the hands and feet and also, pitted keratolysis on both volar surface of the hands. The hitologic findings were those of features of acrokeratosis verruciformis, i.e. the epidermis shows marked hyperkeratosis with slight acanthosis and papillomatosis and circumscribed elevations of the epidermis resembling church spires characteristically.

Indirect fluorescent antibody tests were performed with sera of paragonimiasis patients and skin test positive sera against Paragonimus antigen. Paragonimus antigen was prepared from lyophilized adult worms of P. westermani by defatting with ethyl-ether before extracting with barbital buffered saline. Preparation of Paragonimus antigen for the indirect fluorescent antibody test was based upon Sato's method used for sero-diagnosis of anisakiasis, with Sephadex G-25 instead of Sepharose 4B. The results were as follows: The indirect fluorescent antibody titers of paragonimiasis patient's sera ranged from 1:64 to 1:512, whereas the control sera showed titers of less than 1:16. As controls, Clonorchis patient's sera and parasite-free healthy human sera were used. In indirect fluorescent antibody tests, the skin test positive human sera against Paragonimus antigen showed a positive rate of 41.5 per cent in the case of titers more than 1:40. On the other hand, complement fixation tests on the same sera showed a positive rate of 32.5 per cent in the case of titers more than 1:20.

Muchz-Habermann disease is cutaneous disease of unknown etilogy and characterized by a, polymorphous eruption consisting of papulosquamous, bemorrhagic, ulceronecrotic lesion eventually into varioliform scars. It is also classified into parapsoriasis group according to Broq with parapsoriasis en guttata (pityriasis lichenoides chronica), parapsoriasis en plaques, parapsoriasis en lichenoides. The 61-year-old male patient visited to Dermatologic Department of Severance Hospital due to sudden onset of generalized eruption. He presented pea to fingr tip sized erythematous, silvery maculo-papulo-squamous eruptions on trunk, extre- mities and buttock, but didnt complain of any subjective symptoms except markel fatigue. Skin biopsy was done on right forearm and was confirrr.ed to pityriasis lichenoides et varioliformis acuta by histopathologic finding. The lesion was completely controlled by oral tetracycline 2. Ogm per daily for first 4 wecks and reduced dosage l. Ogin per day for second 2 weeks.

This study aims at analyzing the articulator of human body and its composition using the Magnetic Resonance Image (MRI, 0.5 Telsa). The MRI images were photographed for 1cm per every cm of human body using TR 600ms and TE 20ms spin-echo sequence. For this test, 6 healthy male subjects were sampled. The subject's heights and weights were measured before photographing and then their entire bodies were photographed in the MRI whole body scanner which has a 56cm diameter. It took 90~120 minutes to scan every subject's body during scanning the subjects were allowed to put their both hand beside their femurs. According to his height, each subject were photographed for 180~200 MR slices and every image was analyzed on the tracing paper via X-ray reading View Box. Then, the traced images were all volumized through computer scanner and CAD program, and thereupon, each volume was multiplied by its density coefficient. The results of study can be summarized as follows ; The mass of the bones occupied 8.41±0.62kg, which accounted for 11% of the body mass. The femurs accounted for 19.73±2.73% of the bone mass in terms of bodily articulation. The muscle occupied 39.70±5.28kg which accounted for 51.28±8.98% of the body mass. The part which has the richest muscle mass was femur which accounted for 33.93±5.58% of entire muscle mass. The fat accounted for 24.61±11.6% of the body mass, among which the back waist including inside intestinal fat occupied 30.66±3.64%. It was suggested through this study that MRI analysis is the most suitable method to evaluate the composition of human body and that the data acquired through MRI analysis may apply as references to other indirect or estimated evaluation of human body.

Thirty patient with essential hypertension were administered Manidipine, a new calcium antagonist, 10~20mg once daily to evaluate the hypotensive efficacy and safety for 8 weeks. And the followings were the result. 1) Patients were consists of 14 male, 16 female, aged 53 in average and classified as mild in 21 and moderate in 9 patients. 2) Optimum intial dose was 10mg and 10 to 20mg were the doses recommended. 3) Blood pressure dropped after 8 weeks 24/13mmHg in average, rewarding 80% effectiveness and normalized in 87%. 4) Most frequent side reaction was facial flushing in 5 patiens followed by palpitation and dizziness, all of which did not disturb the continuation of medication. 5) Most of routine laboratory parameter were normal and unchanged between before and after the trial. 6) Overall rating of usefulness was 77%. In conclusion, Manidipine 10 to 20mg once daily regimen is well tolerated and effective in the treatment of mild to moderate essential hypertension.

BACKGROUND: IL-8 is a potent chemotactic cytokine that plays an important role in the host defense mechanism against M. tuberculosis by recruiting inflammatory cells to the site of the infection. Lung epithelial cells, as well as alveolar macrophages are known to preduce IL-8 in response to M. tuberculosis. IL-8 gene expression is mainly regulated on the level of transcription by NF-κB. This study investigated whether or not A549 cells produce IL-8 in NF-κB dependent mechanism in response to macrophages phagocytosing M. tubersulosis. METHODS: Peripheral blood monocytes that were obtained from healthy donors were cultured for 24 h with M. tuberculosis and a conditioned medium(CoMTB) was obtained. As a negative control, the conditioned medium without M. tuberculosis (CoMCont) was used. A549 cells were stimulated with M. tuberculosis, CoMCont and CoMTB and the IL-8 concentration in the culture media was measured by ELISA. The CoMTB induced IL-8 mRNA expression in the A549 cells was evaluated using RT-PCR, and CoMTB induced IκBα degradation was measured using western blot analysis. CoMTB induced nuclear translocation and DNA binding of NF-κB was also examined using an electrophoretic mobility shift assay(EMSA), and the CoMTB induced NF-κB dependent IL-8 transcriptional activity was measured using a luciferase reporter gene assay. RESULTS: CoMTB induced IL-8 production by A549 cells(46.8±4.8 ng/ml) was higher than with direct stimulation with M. tuberculosis (6.8±2.9 ng/ml). CoMTB induced IL-8 mRNA expression increased after 2 h of stimulation and was sustained for 24 h. IκBα was degraded after 10 min of CoMTB stimulation and reappeared by 60 min. CoMTB stimulated the nuclear translocation and DNA binding of NF-κB. The CoMTB induced NF-κB dependent IL-8 transcriptional activity(13.6±4.3 times control) was higher than either CoMCont(2.0±0.6 times control) or M. tuberculosis (1.4±0.6 times control). CONCLUSION: A conditioned medium of peripheral blood monocytes phagocytosing M. tuberculosis stimulates NF-κB dependent IL-8 production by the lung epithelial cells.

Regenerative medicine (RM) aims to replace or regenerate human cells, tissues, or organs to restore or establish the normal function. RM comprises cells, biomaterials for scaffolds, and growth factors. The cells play an important role in regenerative medicine. Biomaterials can form tissue and transmit biological activity signals and promote cell adhesion. The biological growth factor is a signal transmitter necessary to regenerate tissues and organs. Bioprinting as a powerful tool for building tissue and organ structures in the field of tissue engineering has attracted enormous attention as a fabrication methodology for producing 3-dimensional structures. Bioprinting technology will be needed to treat musculoskeletal diseases. This paper will provide information that can be used as a regenerative medicine treatment for musculoskeletal diseases. It will enable the regeneration of the musculoskeletal system consisting of bones, joints, muscles, and nerves.
