Abstract
Previously the authors reported that the fat emulsion of 1-(2-tetrahydrofuryl)-5-fluorouracil, tegafur (FT-207), yielded significantly higher concentrations of tegafur in the lymph and plasma compared to tegafur enteric-coated granules (FT-G). However, the emulsification did not improve the metabolic conversion rate of tegafur to 5-fluorouracil (5-FU). A study was performed to assay the plasma and lymphatic concentrations of tegafur, 5-FU, and uracil in seven patients after radical surgery for gastric carcinoma who were given a combined oral preparation of FT-207 and uracil (UFT). Both lymph and plasma 5-FU levels after UFT were 20 times greater than those after FT-G, although FT-207 levels were not different. Patients given UFT showed significantly greater 5-FU and uracil concentrations in the lymph compared with the plasma. The results of this study suggest a potential use of UFT as an adjuvant postoperative chemotherapeutic agent for gastric carcinoma.

Abstract
A 12-year-old girl, suffering from xeroderma pigmentosum (XP), had mild cutaneous and neurological abnormalities. She showed no neurological abnormalities at the age of seven, but areflexia of the patellar tendons at II. She had no malignant tumours. The skin fibroblasts from the patient were about twice as sensitive to the lethal effects of 254 nm ultraviolet (UV) radiation as those of Group C XP patients, and about twice as resistant as those of typical Group A XP patients. The ability of these fibroblasts to reactivate UV-damage adenovirus 5 was intermediate between those of Group C and typical Group A patients. The patient's cells were assigned to genetic complementation Group A by use of the cell-fusion technique. This is the first case in Japan of a Group A XP patient with mild neurological abnormalities. The mild cutaneous manifestations of this patient may be explained by the residual ability of the cells to repair UV-damaged DNA.

Abstract
Distribution of actin filaments of human epidermal keratinocyte in the primary culture was observed by immunofluorescence staining. In the cytoplasm, actin was distributed diffusely, and strong antiactin immunofluorescence was observed along the leading edge, showing ruffling and the contact zone to the neighboring cell. 12-O-Tetradecanoylphorbol-13-acetate (TPA) induced organization of actin filaments. Many short bundles of actin filaments appeared shortly after the addition of 16 nM TPA, and large actin-containing ribbons of crescent-shape, circular or gyrus-like form were sometimes observed. Phorbol-12-13-diacetate, a non-promoter phorbol ester, induced a similar change, but to a much lesser extent. Addition of 1 mM cycloheximide did not interfere with the organization of actin filaments by TPA. La3+ aborted it completely possibly by replacing Ca2+ at the binding site of the cell surface, and the cultivation in low Ca2+ environment suppressed the effect of TPA. These findings make a contrast to those reported in fibroblasts, and may be linked to the characteristic response of cultured human keratinocytes to TPA in the proliferation of cells and induction of ornithine decarboxylase.

Abstract
We carried out a clinical trial of 1 alpha-hydroxycholecalciferol [1 alpha(OH)D3] at a dose of 1.0 microgram a day on 7 patients with psoriasis vulgaris. These patients had been treated by topical applications of corticosteroids before this study without improvement, and during the clinical trial, treatment of topical corticosteroids was continued on 6 of the 7 patients. Four of 7 patients showed complete remission and marked improvement and 2 additional patients showed minimal improvement of their skin lesions during and after the treatment with 1 alpha(OH)D3. No adverse reactions were noted during the treatment period. The mechanism of the phenomenon we observed has yet to be elucidated. Controlled trials of large numbers of patients with psoriasis vulgaris treated with 1 alpha(OH)D3 are under way.

Abstract
Active forms of vitamin D3, 1 alpha-hydroxyvitamin D3 and 1 alpha,25-dihydroxyvitamin D3, were administered in an open-design study to 40 patients with psoriasis vulgaris in three ways: to 17 patients 1 alpha-hydroxyvitamin D3 was given orally at a dose of 1.0 micrograms/day for 6 months, to four patients 1 alpha,25-dihydroxyvitamin D3 was given orally at a dose of 0.5 microgram/day for 6 months, and 19 patients were given 1 alpha,25-dihydroxyvitamin D3 applied topically at concentration of 0.5 microgram/g of base for 8 weeks. Improvement was observed at the end of the individual study periods in 13 (76%) patients in Group 1 with a mean period of treatment (+/- SD) of 2.7 +/- 0.6 months, in one patient in Group 2 at 3 months after the start of treatment, and in 16 (84%) patients in Group 3 when the chemical was applied for 3.3 +/- 1.2 weeks. No side-effects were observed in any of these trials. These data suggest that psoriasis may respond to active metabolites of vitamin D3 and that abnormalities in vitamin D metabolism or in responsiveness of the skin cells to active metabolites of vitamin D may be involved in the pathogenesis of this skin disease.

Abstract
In an open-design study 1 alpha-hydroxyvitamin D3 was administered orally to 17 patients with psoriasis vulgaris at a dose of 1.0 micrograms/day for 6 months. More than moderate improvement was observed in 13 (76%) of the 17 patients from 2.7 +/- 0.6 months (mean +/- SD) after the start of treatment. No side effects of the treatment were observed. The mechanism of the effect of 1 alpha-hydroxyvitamin D3 requires study, but these data suggest that its oral administration is effective for treatment of psoriasis vulgaris.

Abstract
We report a case with rapidly growing subcutaneous and intra-muscular tumours that were identical histopathologically to a pre-existing left atrial myxoma. No invasion of visceral organs or skeleton was found. This is a very rare case of metastasizing myxoma with wide dissemination and rapid metastastic growth, despite the benign appearance of the original tumour.

Abstract
The influence of a biological response modifier on thoracic lymphocytes was studied clinically and experimentally. The thoracic lymphocytes and peripheral blood were taken from nine cases of gastric cancer relapse before and after the administration of hemolytic streptococci, OK-432 (PIC), for immunological examination. T: B cell ratio, T cell ratio and ADCC activity of the thoracic lymphocytes and peripheral blood were not changed but the NK activities of both were increased. The juvenilization of lymphocytes was reduced but that of the peripheral blood was not changed. The number and the ratio of T cells in the thoracic lymphocytes of Wistar rats were considerably increased by the administration of PIC but they were reduced in the peripheral blood. T-cell subsets of thoracic lymphocytes and peripheral blood were hardly changed by the administration of PIC. In the case immunological treatment, the thoracic lymphocytes and blood lymphocytes should be monitored because their biological specificities are different.

Abstract
The expression and properties of pemphigoid antigen of SV40-transformed human keratinocytes were studied. By indirect immunofluorescence, SV40-transformed keratinocytes in passage 80-85 expressed the pemphigoid antigen as coarsely granular perinuclear fluorescence. To characterize this antigen, NP40 extracts of cells labeled with [14C]amino acids were immunoprecipitated using sera of 8 patients: bullous pemphigoid (6 patients), chronic localized pemphigoid (1 patient), and drug-induced lichen planus pemphigoides (1 patient). These immunoprecipitates were subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis and then fluorographed. All 8 sera precipitated a protein of Mr 240K, while normal human sera did not precipitate this protein. These results indicate that SV40-transformed human keratinocytes synthesize pemphigoid antigen, and that autoantibodies in the sera of pemphigoid patients with different clinical features identify the same antigen of Mr 240K in these cells.

Abstract
The influence of fat emulsification of N1-(2-tetrahydrofuryl)-5-fluorouracil (FT-207) on lymphatic transport was studied in seven postoperative gastric cancer patients. The water-in-oil-type of emulsion of FT-207 (FT-w/o), the oil-in-water-type emulsion of FT-207 (FT-o/w) and an enteric-coated granule of FT-207 (FT-G) each in 1-g doses, calculated in terms of FT-207, were administered orally. Lymph from a thoracic duct fistula, prepared in advance, and from the blood of a peripheral vein was collected simultaneously along a time course after administration to measure the concentrations of FT-207 and 5-fluorouracil (5-FU). For FT-w/o, FT-207, and 5-FU, concentrations were significantly higher, both in the lymph and in the blood, than those for FT-G and FT-o/w. However, no significant differences in FT-207 and 5-FU concentrations were observed between FT-o/w and FT-G. It was concluded that FT-w/o can be useful as an adjuvant chemotherapeutic drug in the postoperative treatment of gastric cancer.

Abstract
The effects of topical administration of 1,25-dihydroxyvitamin D3, as 0.1 and 0.5 microgram per g base, and control base applied to contralateral skin lesions in five patients with persistent psoriasis were compared. In all five, definite and in some cases remarkable improvement of the lesions was seen when 1,25-dihydroxyvitamin D3 at concentration of 0.5 microgram per g base was applied for two to five weeks. No local or systemic toxicity was detected in any patient. Although the mechanism of the improvement is yet to be elucidated, these results show the possible effectiveness of topical 1,25-dihydroxyvitamin D3 on psoriatic skin lesions.

Abstract
A new type of human papillomavirus (HPV), HPV-38b, was isolated from patients with epidermodysplasia verruciformis and was molecularly cloned. This HPV was shown by hybridization experiments to have almost no sequence homology with other types of reported HPVs, but did show homology with HPV-38, which was recently isolated from a melanoma. A physical map and a rough genetic map of the organization of this HPV are presented.

Abstract
Steroid sulphatase activity in peripheral blood lymphocytes was assayed in all available members of three families in which cases of X-linked ichthyosis were frequently seen. Lymphocytes from all the patients with this disease lacked steroid sulphatase activity and some female members who were probably heterozygotes, showed significantly lower enzyme activity compared with other healthy family members and normal controls. This suggest that females heterozygous for X-linked ichthyosis in these families could be traced enzymatically. Three childless females in these families were found to be possible heterozygotes in view of their lower enzyme levels. It was found that polyacrylamide gel electrophoretic mobility of serum low-density lipoproteins was increased in X-linked ichthyosis patients but was not changed in the probable heterozygotes. The detection of individuals heterozygous for X-linked ichthyosis, for the purpose of precise genetic counselling, may be possible by measuring steroid sulphatase activity of peripheral blood lymphocytes.

Abstract
A 5-year-old boy had a nodular erythema, elongated and thickened fingers, and emaciation. His condition was a rare congenital disease inherited as an autosomal recessive trait. Eleven cases have been previously reported in the Japanese literature. The onset is early in childhood, and nodular erythema is an essential and initial finding. Growth retardation and emaciation progress slowly with age. The characteristic clinical features include large eyes, nose, lips, and ears, disproportionately long and thick fingers, and the loss of adipose tissue from the upper half of the body. Cardiomegaly and hypertrophy of the periosteum of the phalanges have been described in some cases.
