Three patients with mycosis fungoides, who were long-term employees of a manufacturer of solid fuel propellants, were seen. Two of these patients had tumorous involvement of the central nervous system, which was successfully treated with radiation therapy. The potential relationship of carcinogens is discussed. 相似文献

OBJECTIVE: This article reports a case of bilateral cleft lip and alveolus (BCLA) for which excessive rapid palatal expansion with a Latham appliance was performed for preoperative alignment of the protruded premaxilla. Postoperative changes of maxillary width were investigated with serial plaster casts. PATIENT AND RESULTS: A 3-month-old girl presented with complete BCLA in which the premaxilla was markedly protruded. Preoperative alignment of the protruded premaxilla with a Latham appliance was planned to facilitate primary lip repair. The appliance was placed when the patient was 4.5 months old. The necessary palatal expansion was estimated to be 7.0 mm in order to move the premaxilla backward into the ideal position. After palatal expansion and posterior repositioning of the protruded premaxilla, the primary operation, including cheiloplasty and gingivoperiosteoplasty, was performed when the patient was 7 months old. Excessive maxillary expansion might be a cause of transverse maxillomandibular discrepancy. Measurement with serial plaster casts demonstrated that maxillary widths increased from 42.3 mm pretreatment to 49.0 mm after orthopedic treatment but relapsed markedly to 43.5 mm at 3 months after the primary operation. Therefore, the net change of maxillary widths was only 1.2 mm. After alignment of the protruded premaxilla, tension-free soft tissue repairs were performed, and a harmonious alveolar arch was obtained without change in maxillary width. CONCLUSION: These results indicate that this method is useful for preoperative management of BCLA with protruded premaxilla. 相似文献

Trichorhinophalangeal syndrome (TRPS) type I is characterized by slowly progressing systemic osseous dysplasia, exhibiting craniofacial and other skeletal deformities. However, there have been few reports describing this syndrome after undergoing orthognathic surgery. In this report, we present a patient with TRPS I who successfully underwent orthognathic surgery. In addition, we examined the skeletal stability of the patient for 2 years after the surgery. 相似文献

Neokadsuranic acid A, which is the first triterpenoid with the 14(13-->12) ABEO lanostane skeleton, was isolated from KADSURA HETEROCLITA together with (24 Z)-3-oxo-lanosta-8,24-dien-26-oic acid. The present paper deals with the isolation and structure elucidation of these two new compounds. 相似文献

Summary. The nucleotide sequence of the genome segment 2 (S2) of rice gall dwarf virus (RGDV), a phytoreovirus, when compared with
the amino acid sequence of a component protein of the virus, showed that S2 potentially encoded a 127K minor outer capsid
protein. This 127K protein designated as P2 and the 127K minor outer capsid protein (also termed P2) of rice dwarf virus (RDV)
are similar in size, located in the outer capsid, and have well-conserved predicted polypeptide sequences, suggesting similar
functions. Infectivity to insect vector cell monolayers of RGDV was maintained and the P2 protein was retained irrespective
of carbon tetrachloride (CCl4) treatment. This is in contrast to the infectivity of RDV which is removed along with P2 protein following CCl4 treatment. RGDV with P2 was acquired by vector insects and transmitted to host plants, although RDV lacking P2 could not
be transmitted to plants as previously published. These results imply that RDV and RGDV require P2 proteins for virus infectivity
to vector insects.
