A case of refractory anaemia with p53 point mutation at codon 249 (AGG to ATG).

Although mutations of the p53 tumour-suppressor gene have been observed occasionally in the advanced stages of myelodysplastic syndromes (MDS), they have not been detected in early refractory anaemia (RA) or RA with ring sideroblasts phases. Using single-strand conformation polymorphism analysis and direct sequencing, we searched for p53 mutations in a patient who progressed from RA to overt leukaemia. A p53 mutation at codon 249 (AGG to ATG) was observed in RA, RA with excess of blasts in transformation and overt leukaemia. We describe a case of MDS with p53 mutation at codon 249 detected in the RA phase.

Symptomatic subacute subdural hematoma associated with cerebral hemispheric swelling and ischemia.

A 55-year-old man with traumatic acute subdural hematoma (SDH) was managed nonsurgically because of having isolated mild headache that resolved within a week. However, the patient developed an acute onset of amnestic aphasia 12 days post-trauma. Although the SDH itself did not increase in volume, remarkable swelling of the ipsilateral cerebral hemisphere was observed on CT scanning. Craniotomy was required since the main component of the SDH was solid and partially organized. Post-operative recovery from his speech disturbance was delayed, necessitating speech therapy for more than two months. Additionally, decreased cerebral blood flow on the affected side was observed even 3 months after injury. Symptomatic subacute SDH exclusively presenting as focal neurological deficits, though very rare,is worthwhile to be kept in mind as a pitfall in nonsurgical management of acute SDH.

[A case of severe acute hepatorenal failure due to Aeromoas hydrophila septicemia].

A case of septicemia due to Aeromonas hydrophila (A. hydrophila) in a 54-year-old male suffering from progressive severe jaundice and fatigue is reported. The patient developed multiple organ failure despite aggressive therapy including plasma exchange and glucose-insulin therapy. Upon admission to our hospital, therapy was started with ampicillin (ABPC) 4 g/day, gentamicin (GM) 120 mg/day, hemodialysis, continuous hemofiltration, catecholamines and a respirator, but he expired on the 2nd hospital day. Blood culture and histology revealed A. hydrophila. Postmortem examination showed alcoholic liver fibrosis which was most likely liver cirrhosis. In the literature, patients with septicemia due to Aeromonas had underlying hepatic cirrhosis more often than did those with septicemia due to other gram-negative bacilli. Therefore, it is important-to consider the possibility of liver cirrhosis in patients with A. hydrophila septicemia.

Effect of recombinant human granulocyte colony-stimulating factor on combination therapy with aztreonam and clindamycin for infections in neutropenic patients with hematologic diseases.

The present multicenter study was performed to evaluate the effect of recombinant human granulocyte-colony stimulating factor (rhG-CSF) on combination therapy using aztreonam (AZT) and clindamycin (CLDM) to treat severe infection in neutropenic patients with hematologic diseases. Forty-three neutropenic patients with infections (rhG-CSF group) were treated with AZT (2 g) and CLDM (600 mg) 2-3 times daily as well as rhG-CSF (Lenograstim or Filgrastim: 2-5 mu/kg/day). The clinical efficacy of this regimen was compared to that obtained in 44 febrile neutropenic patients, with hematologic diseases, who received only AZT and CLDM in a previous study (historical control group). The overall efficacy rate was 69.8% (30/43) in the rhG-CSF group and 65.9% (29/44) in the historical control group. Although the neutrophil count was significantly increased and C-reactive protein tended to be lower in the rhG-CSF group, the daily maximum body temperature profiles of the 2 groups were nearly the same. These results suggest that rhG-CSF is of little benefit in the treatment of single infectious episodes in neutropenic patients, and that appropriate antibiotic therapy is more important.

Local delivery of antithrombotic drug prevents restenosis after balloon angioplasty in atherosclerotic rabbit artery.

We investigated the ability of various antithrombotic drugs, delivered locally, to prevent restenosis after angioplasty in hypercholesterolemic rabbits. After dilating atherosclerotic iliac stenoses by balloon angioplasty, a low dose of heparin or a new antithrombotic drug, such as low molecular weight heparin (fragmin), argatroban, or batroxobin, was delivered locally using the balloon double-occlusion technique. In 1 group, high-dose heparin was administered intravenously. Animals that received no drugs served as a control group. After angioplasty, the stenotic segment was dilated and the mean percentage luminal stenosis fell from 89% to 9% in the group that received locally delivered heparin, from 88% to 7% in the group that received locally delivered argatroban, from 87% to 11% in the group that received locally delivered fragmin, from 88% to 15% in the group that received locally delivered batroxobin, from 82% to 18% in the group that received i.v. heparin (p < 0.0001 compared with before angioplasty in each case), and from 84% to 17% in the control group (p < 0.005 compared with before angioplasty). Twenty-eight days after angioplasty, the percentage luminal stenosis remained at 14% in the group that received locally delivered argatroban, 15% in the group that received locally delivered fragmin, and 28% in the group that received locally delivered batroxobin, whereas it increased to 45% in the group that received i.v. heparin, 30% in the group that received locally delivered heparin and 72% in the control group (p < 0.05 compared with after angioplasty in each case). Thus, local delivery low doses of new antithrombotic drugs prevents restenosis after angioplasty without affecting systemic coagulability; heparin, whether administered locally or intravenously, was less effective than the new drugs in preventing restenosis.

Immunochemical and biochemical identification of the rice seed protein encoded by cDNA clone A3-12.

Previously isolated cDNA clone A3-12 that was expressed in E. coli as the fusion protein with Trp E showed immunoreactivity with the mouse antibody raised against isolated alpha-globulin from rice seed. The N-terminal amino acid sequences determined for the purified alpha-globulin and its tryptic peptides were identical with the deduced amino acid sequence reported, except for two residues at the protein N terminus. An error in the reported sequence was confirmed by re-sequencing the cDNA, the nucleotide sequence for the two N-terminal residues being shown to be CAGCTG and not CACGTG. Thus, the protein encoded by cDNA clone A3-12 was identified to be the major rice seed globulin, alpha-globulin, with an apparent molecular mass of 26kDa.

Characterization of the bovine kappa-casein gene promoter.

kappa-Casein gene promoter was localized within a 570-bp fragment (-552/+18) of a 5'-flanking region by the gene transfection assay. Deletion mutation analysis in mammary epithelial cell line, HC11, suggested that there are regulatory element in a region from -439 through -125. Some nuclear proteins from lactating rate mammary gland bind to this region specifically. One of them expressed preferentially during pregnancy bound to a 132-bp fragment (-439/-308) and another expressed preferentially during lactation bound to a 183-bp fragment (-307/-125).

Two cases of empty sella syndrome with variable dexamethasone-suppressibility of ACTH and cortisol.

We here describe two patients with empty sella syndrome who had variable and abnormal ACTH and cortisol secretory profiles. The patients are a 58-year old male and a 41-year old female, both of whom were neurotic. In both cases, low-dose dexamethasone suppression tests (1 mg, p.o., overnight) caused variable responses, such as a paradoxical increase, insufficient decrease or normal decrease in ACTH and cortisol depending on the period when they were performed. The circadian rhythm of ACTH and cortisol also showed variable patterns. Abdominal CT showed slight enlargement of both adrenal glands. Adrenal scintigraphy after dexamethasone suppression (3 mg, p.o., 7 days) revealed uptake into both adrenal glands. MRI of the brain indicated empty sella, but failed to show evidence of pituitary adenoma. It remains to be elucidated whether these secretory profiles of ACTH and cortisol in the two cases are only to be regarded as secondary changes associated with neurosis, as reported in depression or alcoholism, or the two cases share some pathogenetic mechanism with cyclic Cushing disease.

Bilateral chronic subdural hematomas associated with intracranial hypotension--case report.

A 56-year-old female presented with chronic subdural hematoma due to spontaneous (primary) intracranial hypotension (SIH). She was admitted in a deep coma. Computed tomography showed bilateral chronic subdural hematomas with tight basal cisterns. Percutaneous aspiration of the chronic subdural hematoma with the twist drill revealed negative pressure. The neurological symptoms rapidly improved postoperatively, but the chronic subdural hematoma recurred three times, requiring further aspiration procedures. Patients with SIH may develop subdural hematoma requiring surgical treatment.

Adult moyamoya disease progressing from unilateral to bilateral involvement .

A 30-year-old female and a 38-year-old male developed "definite" moyamoya disease after presenting with "probable" moyamoya disease manifesting as ischemic stroke. Angiography at first presentation demonstrated unilateral involvement with normal contralateral findings. The cases were classified as adult type "probable" moyamoya disease according to the diagnostic criteria. Follow-up angiography demonstrated the occlusive lesions had become bilateral, satisfying the criteria for "definite" cases. Serial angiography is required in adults presenting with "probable" moyamoya disease manifesting as ischemic stroke.

The transcondylar approach to extradural nonneoplastic lesions of the craniovertebral junction.

Ventral extradural lesions at the craniovertebral junction are commonly exposed through the transoral or transmaxillary approach. The disadvantages of these approaches include: 1) difficulty in reaching laterally located lesions; 2) ineligibility of patients with an intradental distance of less than 25 mm or severe macroglossia; 3) the need for a separate procedure for stabilization and fusion; and 4) the risk of infection from transgressing a contaminated field. In this report, the authors describe the use of the transcondylar approach to extradural nonneoplastic lesions of the anterior craniovertebral junction for decompression and stabilization. Advantages of this approach include: 1) a short distance to the lesion; 2) a wide surgical envelope; 3) direct visualization of the dural sac, eliminating manipulation of the brainstem or upper spinal cord; 4) easy identification and control of the ipsilateral vertebral artery; 5) direct visualization and preservation of the lower cranial nerves; and 6) a sterile field. In addition, occipitocervical fusion and instrumentation can be performed during the same procedure. The transcondylar approach, based on anatomical studies in cadavers, was used to treat eight patients with ventral nonneoplastic lesions at the craniocervical junction. The technique and results are described.

[ULUUS, the first Japanese medicine with a western name].

"ULUUS" is a patent medicine which was put on sale when the Japanese started to adopt Western Medicine brought in from Holland. It is regarded as the first medicine to have a Western-style name in Japan. In those days, ULUUS was thought be a useful medicine for patients with diseases called Tan, Ryuin and Shakki, causing the excretion of phlegm and bad accumulations in the body through expectoration, urine of feces. We recently obtained an ULUUS medication which was made in around 1870. It contains 15 tablets pressed neatly onto a sheet and has an inner wrapper, middle wrapper and outer wrapper made from 3 kinds of Japanese paper...

[Susceptibilities of bacteria isolated from patients with respiratory infectious diseases to antibiotics (1993)].

Bacteria isolated from respiratory tract infections were collected in cooperation with institutions located throughout Japan, since 1981, and the Ikemotor et al. have been investigating susceptibilities of the isolates of various antibacterial agents and antibiotics, and the relationships between the isolates and backgrounds of the patients and so forth each year. We discuss the results in detail. In 20 institutions around the entire Japan from October 1993 to September 1994, 584 strains of bacteria were isolated mainly from sputa of 473 patients with respiratory tract infections and presumed to be the etiological agents. MICs of various antibacterial agents and antibiotics were determined against 91 strains of Staphylococcus aureus, 98 strains of Streptococcus pneumoniae, 122 strains of Haemophilus influenzae, 91 strains of Pseudomonas aeruginosa (non-mucoid), 34 strains of Pseudomonas aeruginosa (mucoid), 42 strains of Moraxella subgenus Branhamella catarrhalis, 25 strains of Klebsiella pneumoniae etc., and the drug susceptibilities of these strains were measured except the strains which died during transportation. 1. S. aureus S. aureus strain sfor which MICs of methicillin was higher than 4 micrograms/ml (methicillin-resistant S. aureus) accounted for 56.0%, but this frequency of the drug resistant bacteria was lower than the previous year's 61.4%. Arbekacin and vancomycin showed the highest activities against MRSA and MIC80s were 1 microgram/ml. 2. S. pneumoniae Benzylpenicillin among the penicillins showed potent activities against S. pneumoniae. Cefuzonam, cefotaxime and cefmenoxime among the cephems showed excellent antimicrobial activities against S. pneumoniae. Imipenem; carbapenems, showed the most potent activity, and MIC90 was 0.063 microgram/ml. 3. H. influenzae All the drugs tested were quite active against H. influenzae. Cefotaxime, cefmenoxime, cefuzonam and cefixime among the cephems showed the most potent activities, and MIC90 were 0.063 microgram/ml against H. influenzae. Ofloxacin also showed MIC90 of 0.063 microgram/ml. 4. P. aeruginosa (mucoid) Tobramycin showed the most potent activity against P. aeruginosa (mucoid), and MIC80 was 1 microgram/ml. Ceftazidime, cefsulodin, imipenem, aztreonam, gentamicin and ciprofloxacin showed potent activities with MIC80s of 2 micrograms/ml. 5. P. aeruginosa (non-mucoid) Tobramycin showed the highest activity against P. aeruginosa (non-mucoid), and MIC80 was 1 microgram/ml, followed by ciprofloxacin with MIC80 of 2 micrograms/ml. Comparing to activities against P. aeruginosa (mucoid), all the drugs tested had relatively low activities against P. aeruginosa (non-mucoid). 6. K. pneumoniae. The activities of all drugs except ampicillin and minocycline were high against K. pneumoniae. Cefozopran, imipenem and carumonam showed the highest activities and MIC80s were 0.125 microgram/ml. Flomoxef showed the next highest activities with an MIC80 of 0.25 microgram/ml. 7. M.(B.) catarrhalis Imipenem showed the most potent activity against M.(B.) catarrhalis, with an MIC80 of 0.063 microgram/ml, followed minocycline and ofloxacin with their MIC80s of 0.125 microgram/ml. We also investigated year to year changes in the background of patients, as well as types of respiratory infectious diseases, and the etiological agents. As for patients background, there were many infectious diseases found among patients a high age bracket, and the patients over age 60 accounted for 61.3% of the diseases. The distribution by respiratory tract infections was as follows: chronic bronchitis and bacterial pneumonia accounted for the greatest numbers of cases with 31.1% and 26.0%, respectively, followed by bronchiectasis with 10.4%. In this year chronic bronchitis under age 29 were 41.7%, thus was much higher than 12.5% in previous year. This marked change was first noted in your research during the recent 5 years.

[Susceptibilities of bacteria isolated from patients with respiratory infectious diseases to antibiotics (1994)].

Bacteria isolated from lower respiratory tract infections were collected in cooperation with institutions located throughout Japan, since 1981. IKEMOTO et al. have been investigating susceptibilities of these isolates to various antibacterial agents and antibiotics, and characteristics of the patients and isolates from them each year. Results obtained from these investigations are discussed. In 23 institutions around the entire Japan, 492 strains of presumably etiological bacteria were isolated mainly from the sputum of 421 patients with lower respiratory tract infections from October 1994 to September 1995. MICs of various antibacterial agents and antibiotics were determined against 70 strains of Staphylococcus aureus, 101 strains of Streptococcus pneumoniae, 92 strains of Haemophilus influenzae, 61 strains of Pseudomonas aeruginosa (non-mucoid strains), 25 strains of Pseudomonas aeruginosa (mucoid strains), 48 strains of Moraxella subgenus Branhamella catarrhalis, 14 strains of Klebsiella pneumoniae etc., and the drug susceptibilities of these strains were assessed except for those strains that died during transportation. 1. S. aureus. S. aureus strains for which MICs of oxacillin were higher than 4 micrograms/ml (methicillin-resistant S. aureus) accounted for 51.4%, but the frequency of the drug resistant bacteria decreased comparing to the previous year's 56.0%. Vancomycin showed the highest activity against S. aureus with MIC80 of 0.5 microgram/ml. 2. S. pneumoniae. Most of the drugs tested showed potent activities against S. pneumoniae. Imipenem of carbapenems showed the most potent activity with MIC80 was 0.063 microgram/ml. Erythromycin and clindamycin showed low activities with MIC80s > or = 256 micrograms/ml. Among these strains, however, 46.5% and 68.3% of strains, were quite sensitive toward these agents, respectively, with MICs of 0.063 microgram/ml. 3. H. influenzae. The activities of all drugs were potent against H. influenzae tested. Cefmenoxime a cephem, showed the most potent activity, the MICs of this drug against all of the 92 strains were 0.063 microgram/ml. Ofloxacin also showed a potent activity, and inhibited about 96% of strains with MIC of 0.063 microgram/ml. 4. P. aeruginosa (mucoid strains). Tobramycin showed the most potent activity against P. aeruginosa (mucoid strains) with MIC80 of 0.5 microgram/ml. Gentamicin, arbekacin and ciprofloxacin showed next potent activities, and their MIC80s were 2 micrograms/ml. 5. P. aeruginosa (non-mucoid strains). Tobramycin showed the most potent activity against P. aeruginosa (non-mucoid strains) with MIC80 of 2 micrograms/ml. Comparing to the activities against P. aeruginosa (mucoid strains), the activities of all the drugs tested were lower against P. aeruginosa (non-mucoid strains). 6. K. pneumoniae. Carumonam showed the most potent activity against K. pneumoniae with MIC80 of 0.063 microgram/ml. Cefozopran showed the next most potent activity with MIC80 of 0.125 microgram/ml. Ampicillin and cephems except cefpodoxime, cefozopran and cefditoren showed low activities and their MIC80s were > or = 16 micrograms/ml, and their MICs were all higher than > or = 4 micrograms/ml. 7. M. (B.) catarrhalis. Imipenem and ofloxacin showed the most potent activities against M. (B.) catarrhalis, their MIC80s were 0.063 microgram/ml. Erythromycin and minocycline showed the next highest activities with their MIC80s at 0.25 microgram/ml. Also, we investigated year to year changes in the background of patients, the respiratory infectious diseases, and the etiology of bacteria. Patients characteristics, in this period of investigation showed varieties of infectious diseases found in patients in a high age bracket, and the patients over age 60 accounted for 62.0% of all the cases. Different lower respiratory tract infectious were distributed as follows: chronic bronchitis and bacterial pneumonia accounted for the greatest number of cases with 35.6%, 27.1%, respectively, followed by

[Clinical study on a concomitant therapy with fluconazole and human recombinant granulocyte colony stimulating factor in the treatment of systemic fungal infections with hematological disorders].

The clinical efficacy and the safety of concomitant therapy with fluconazole and recombinant human granulocyte colony stimulating factor (rhG-CSF) was compared with fluconazole monotherapy in neutropenic patients with hematological disorders. The clinical efficacy rate was 73.5% (25/34) in the combination therapy and 48.1% (37/77) in monotherapy. The difference between the two is statistically significant. Side effects were not observed in the combination group, but laboratory abnormalities were found in 6 patients with an incident rate of 11%. The combination therapy with fluconazole and rhG-CSF may be selected as empiric therapy for systemic fungal infection associated with hematological disorders, since this combination therapy showed high efficacy and low incident of side effects. Some patients, however, did not show increased neutrophil counts in spite of rhG-CSF administration.

Carboxy-terminal cytoplasmic domain of mouse butyrophilin specifically associates with a 150-kDa protein of mammary epithelial cells and milk fat globule membrane.

A cDNA encoding mouse butyrophilin was obtained by reverse transcriptase-coupled polymerase chain reaction (RT-PCR) using poly (A)+ RNA from lactating mouse mammary gland as a template and screening a cDNA library with the RT-PCR-amplified fragment as a probe. DNA sequencing and computer analysis revealed that it has a rather long 3'-untranslated sequence and that the carboxy-terminal cytoplasmic domain was well conserved between mouse and bovine butyrophilins. To elucidate the biological function of butyrophilin, the cytoplasmic region expressed as fusion protein with glutathione S-transferase (GST) was purified and incubated with the cell lysate of mouse mammary epithelial cell lines, COMMA-ID and HC11. A 150-kDa protein was shown to specifically associate with the cytoplasmic domain and the protein increased in amount when the cells were treated with basal medium supplemented with lactogenic hormones such as prolactin, insulin and glucocorticoid. N-terminal amino acid sequencing indicated that the protein is xanthine dehydrogenase/oxidase which has been cloned from mouse liver. Further, the cytoplasmic domain also bound xanthine dehydrogenase/oxidase from bovine milk fat globule membrane. These results suggest that butyrophilin might be physiologically associated with xanthine dehydrogenase/oxidase and might function in a complex form in milk fat secretion.
