PAS staining was used to assess the glycogen content of psoriatic epidermis, in 35 patients with active psoriasis, 25 patients with inactive psoriasis and 21 normal control subjects. The investigations were also carried out by the disease type, sex, duration of illness, site of biopsy and subjective syrrptom such as itching sensation. Being compared with the active, izractive and normal control groups,7 of R5 active cases and 4 of 25 inactive cases were resulted in strong PAS positive reactions. In 21 ornmal aontrol group, the most cases gave PAS negative reaction, except 2 cases of the week PAS positive reactions. Being compared with disease types, 11 of 5I psoriasis vulgaris cascs was resulted in strong PAS positive reactions and psoriasis guttata cases were resulted in slight PAS positive reaction. among half of their ca.ses. Being iompared with the FAS staining intensity in accordance with the itcbing eensation, R of 6 with severe itching and 4 of 29 cases without itching were resultel in strong PA3 posltive reactions. There were no significant differenees in the sex, age, duration of illness and biopsy site aspects.

For the non-invasive evaluation of cardiac performance in hyperthyroidism, fractional systolic and diastolic time intervals were determined in 96 female patients with hyperthyroidism from the mechanocardiograms which included apexcardiograms together with electrocardiograms, phonocardiograms and carotid arterial pulse tracings. The observed values of the time intervals inversely related to heart rate, i.e., ejection period, mechanical systole, isovolumic relaxation time and active ventricular filling period, were significantly shortened in proportion to the severity of the disease in general, as determined by the rate of the radioactive iodine uptake of the thyroid glands. However, these values were not significantly different from those of the predicted for heart rate, except for one of mechanical systoles which is a time interval from the onset of the systolic upstroke in the apexcardiogram to the second aortic sound. This suggests that the shortening of these observed values is promarily due to tachycardia associated with hyperthyroidism. One the other hand, the observed values of the time intervals unrelated to heart rate, i.e., electromechanical delay, isovolumic contraction time together with one of its components, namely ventricular pressure elevation time, and rapid ventricular filling period, were significantly shorter than those in the controls, although the degree of the shortening was not related to the degree of the radioactive iodine uptake of the thyroid gland. It appears that the shortening of these time intervals is related to the altered cardiac function caused by hyperthyroidism and, in particular, that of the isovolumic contraction time and ventricular pressure elevation time reflects enhancemet by the thyrotoxic myocardial contractility.

Hepatitis G virus (HGV) is a single-strand RNA virus in the Flaviviridae family, it was recently identified from the plasma of a patient with chronic hepatitis. HOV infection may cause acute and chronic liver disease by blood transfusion, drug addicts, hemophilia, and multiple sexual partners. But clinical significance of infectious pathway is still unclear. In this report, we amplified HGV RNA by reverse transcription-PCR (RT-PCR) by primers within the highly conserved 5'-noncoding region (NCR) and used restriction fragment length polymorphism (RFLP) method for the polymorphism analysis of amplified HGV gene. HGV was shown to be present in 7 of 78 (9.0%) from HCV RT-PCR positive serum samples and 5 of 58 (8.6%) from HCV RT-PCR negative serum samples. From the RFLP method HGV divided into four genotypes in 12 positive samples. Therefore, HGV genotype was distributed at least four different types in Korea.

In order to understand epidemiologic characteristics of dioxins related health impacts, 107 diox in-related literatures published up to May, 1993 were thoroughly reviewed. The results obtained are as follows: 1. Review studies on dioxins can be classified into two types : one is studies concentrated on one specific subject related to dioxins such as the effects on skin, birth outcomes, metabolic machanisms in the human body, major sources of exposure to the general population, immunotoxicity, association between dioxins and cancers, and research methods on effects of dioxins. The other is review studies dealing with overall aspects of dioxins, among which the report published by Academy of Science of United Stateds of America in 1993 is the most recent one. 2. Judging by consistency of results and biological plausibility, there were three groups of diseases ; diseases having causal relationship, having possibilities of causal relationship, and having no causal relationship for the time being. 1) The diseases showing causal relationship were lung cancer, Hodgkin 'disease, non-Hodgkin 'lymphoma, soft tissue sarcoma, chlordane, and polyneuropathy 2) the diseases showing possibilities of causal relationship were stomach cancer, lymphatic and haematopoietic cancer, multiple myeloma, skin cancer, diseases of digestive system, and CNS deformity among children born to the people exposed. 3) The diseases showing no causal relationship were oral and laryngeat cancer, esophageal cancer, prostate cancer, kidney cancer, bladder cancer, brain and CNS cancer, diseases of circulatory and respiratory systems. There were numerous diseases of digestive system, which showed difficulty in establishing definite causal relationship owing to the lack of consistency among researchers. 3. Even though papers dealt with dioxinrelated mortality and morbidity studies showed high mortality rate from accident, biological plausibility explaining causal relationship between them should be sought further. 4. There was a high prevalence of hearing loss among Vietnam veterans, and it seemed rather related to the explosive noise in combat than dioxin itself. 5. The current TCDD levels of Vietnam veterans were almost the same as those of the general population.

BACKGROUND: Transforming growth factor-beta(TGF-beta) has multiple regulatory effects on cells of the immune system, and it has been suggested that differentiation of lymphoid cells is influenced by low concentra tions of this cytokine. OBJECTIVES: The aim or this study was to investigate the role of TGF-beta in regulation of T cell growth and differentiation, and to compare this effect with that of other cell signals known to be important in T cell ontogeny. METHODS: We used the CTLL-2 cell line in the presence of IL-2. Surface phenotype expression was analysed to see whether these cells could be switched to the other subtype of cells. RESULT: Treatment of CTLL-2 cells with TGF-beta resulted in dose dependent growth inhibition and morphological changes. Curing routine passage, less than 5% of cells were CD8alpha positive, whereas 38% of cells expressed CD8alpha when treated with IL-2 plus TGF-beta. However, TPA plus calcium ionophore, IFN-gamma, or TNF-alpha caused no significant changes in the proportion of CD8 cells. CONCLUSION: Our results show that this experiment can be a useful model for investigating CD8 precursor potentials in populations of CD4-CD8-(double negative) cells, and such a model may offer a way to study the molecular regulation of CD8 gene expression.

A case of complete loss of penile skin treated with scrotal skin graft was presented in a 26 year old male. This case was noted to be a complete loss of penile skin which was developed under local anesthesia with formalin 30 cc during circumcision. The implantation of the penis in the scrotum was performed by the scrotal tunnel method. Complete logs of penile skin was restored by implanting the denuded surface under the subcutaneous tissue of the scrotum.

Twenty one units of platelet-rich plasma(PRP) were prepared from healthy volunteer blood donors, and each unit of the PRP was divided into two aliquots by using transfer bags. Using SEPACELLTM leukocyte-removal filters, each one aliquot of the PRP was filtered immediately after preparation, and the other aliquot was filtered after a 48-hour storage at a room temperature with continuous agitation. Belbre and after filtration, platelet numbers and two platelet activation markers, CD62 and CD63, were measured using hematologic autoanalyzer and'flow cytometry, respectively. The results were as follows: 1. The platelet numbers in the PRP were reduced after filtration. 2. On the point of the preparation of PRP, the mean percentage of CD63-posititve platelets(s32.86+/- 11.3.5%) was highehr than that of CD62-positive platelets(14.63+/-11.22%). 3. When filtered immediately after preparation of PRP, the CD62-positive platelets were significantly reduced(13.23+/-10.43%), however, CD63-positive platelets were not significantly reduced(29.83+/-11.05%). 4. After 48-hour storage, both two activation markers were increased, and the markers were significantly higher in the PRPs stored after filtration than in those stored without filtration. In conclusion CD63 would be a more sensitive platelet activation marker than CD62, and the platelets expressing CD62 seemed to be removed more than those expressing CD63 during filtration.
