Abstract
To further elucidate the role of dietary frying oil in the pathogenesis of autoimmune diseases, two groups of NZB/W F1 mice were fed with diets containing 20% fresh oil and frying oil, respectively. All these mice were followed up serum anit-DNA antibody levels, proteinuria and life span regularly. Our data suggested: 1) higher IgG anti-ss, dDNA antibody levels were noted in mice fed with fresh oil compared to those of the frying oil group; 2) lipopolysaccharide (LPS)-stimulated spleen cells of mice fed with frying oil produced higher IL-10 compared to that of fresh oil group; 3) IL-6, TNF-alpha and PGE2 produced by macrophages of dietary frying oil group were higher, although not statistically significant, than those of fresh oil group. Different degree of deterioration of dietary oil has been found to affect immune response in autoimmune mice.

Abstract
1. The effects of hypoosmotic stress on cell volume and amino acid efflux were evaluated in the human neuroblastoma cell line CHP-100 with the Coulter Counter Multisizer and radiolabeled amino acid efflux, respectively. 2. CHP-100 cells swelled by approximately 35 +/- 5% (means +/- SE) when the osmolarity of the solution was decreased from 290 to 190 mOsm/kg H2O. The rapid swelling was followed by a biphasic regulatory volume decrease (RVD). 3. In cells loaded with 14C-taurine, hypoosmotic stress induced a 300 +/- 22% (n = 23, P < 0.05) increase in taurine efflux compared with controls. This efflux was inhibited by the chloride channel blockers 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB), 4,4'-diisothio-cyanostilbene-2,2'-disulfonic acid (DIDS), niflumic acid and by the volume-activated anion channel blocker tamoxifen. In addition, the swelling-activated taurine efflux was dependent upon extracellular calcium. 4. Similarly, in cells loaded with 14C-glycine, hypoosmotic stress significantly increased glycine efflux, which was also sensitive to NPPB. In contrast, efflux of 3H-glutamate was not significantly altered after hypoosmotic stress. 5. With the use of patch clamp recording techniques, Cl- channels were activated in cell attached patches after exposure to hypoosmotic solutions. 6. In nystatin perforated patches, permeability of the hypoosmotically activated anion channel was observed to be SCN- > I- > Br- > Cl- >> Glutamate. 7. It is concluded that in CHP-100 cells, anion channels are activated during hypoosmotic stress and these channels represent a pathway for efflux of amino acids.

Abstract
Tacrine [1,2,3,4-tetrahydro-9-acridinamine monohydrochloride monohydrate (THA), Cognex] is a potent acetylcholinesterase inhibitor recently approved for treatment of mild-to-moderate Alzheimer's disease. The potential for THA and/or a metabolite of THA to accumulate in brain tissue was investigated by autoradiographic and metabolic profiling techniques in rats given single and multiple doses of [14C]THA. In addition, the brain-to-plasma distribution time course of orally administered 1-hydroxy-THA (1-OH-THA, 24 mg/kg), a primary rat metabolite with anticholinesterase activity, was also examined. Results from a 16 mg/kg single-dose study showed THA to cross the blood-brain barrier readily and concentrate in brain tissue, approximately 5-fold compared with plasma. The metabolite 1-OH-THA was found in much lower amounts relative to THA and when given separately at a similar dose the levels in brain tissue were comparable with plasma concentrations. After multiple-dose administration, THA concentrations in brain tissue were approximately 3-fold higher than those achieved after a single oral dose. However, concentration of 1-OH-THA metabolite increased only 50%. These data suggest a marked difference between the ability of THA and 1-OH-THA to accumulate in brain tissue and may reflect differences in lipophilicity as estimated by calculated log p values. The relevance of THA accumulation in brain tissue to delays observed in THA clinical management of Alzheimer's disease remains to be established.

Abstract
The human herpes simplex virus type 1 (HSV-1) transactivator VP16 and its homolog from bovine herpes-virus 1 (BHV-1) can each recruit the human homeodomain protein Oct-1 into a transcriptional regulatory complex. Here, we show that these two Oct-1 coregulators possess similar, if not identical, homeodomain recognition properties but possess different virus-specific cis-regulatory specificities: the HSV-1 VP-16 protein activates transcription from the HSV-1 VP16 response element, and the BHV-1 VP16 protein activates transcription from the BHV-1 VP16 response element. A distinct 3-bp segment, the D segment, lying 3' of the canonical TAATGARAT motif (where R is a purine) in the VP16 response element is responsible for the differential cis element recognition and transcriptional activation by these two homeodomain coregulators. These results demonstrate how a single homeodomain protein can direct differential transcriptional regulation by selective association with homologous homeodomain coregulators.

Abstract
The effects of hypotonic shock on cell volume, taurine influx and efflux were examined in the human erythroleukemic cell line K562. Cells exposed to hypotonic solutions exhibited a regulatory volume decrease (RVD) following rapid increases in cell volume. Cell swelling was associated with a increased taurine influx and efflux. The volume-activated taurine pathway was Na(+)-independent, and increased in parallel with increasing cell volume. The chloride channel blocker, 2,5-dichlorodiphenylamine-2-carboxylic acid (DCDPC), completely blocked the volume-activated taurine influx and efflux, while [dihydroindenyl)oxy]alkanoic acids (DIOA) and 5-nitro-2-(3-phenylpropylamino)benzoic acid (NPPB), an anion exchanger and anion channel blocker, respectively, also inhibited significantly. These results suggest that taurine transport is increased in response to hypotonic stress, which may be mediated via a volume-activated, DCDPC-sensitive anion channel.

Abstract
In initial and follow-up investigations of neuropsychological function in a patient with elemental mercury intoxication, his scores were compared with those of a group of normal control subjects matched for sex, age and education. Each subject received a comprehensive neuropsychological examination including a personality inventory. On the initial examination the results indicated that the patient had a significant depression of performance intellectual functioning, impairments of attention, non-verbal short-term memory and visual judgement of angles and directions, psychomotor retardation and personality changes including depression, anxiety, desire to be alone, lack of interest and sensitivity to physical problems. Such an impairment picture is compatible with the previous observations of individuals with chronic exposure to elemental, organic or inorganic mercury. The follow-up study was undertaken about 1.5 years later. The results show that the patient's cognitive and personality functions were fully recovered. Our findings thus suggest a reversibility of impaired neuropsychological function in persons with elemental mercury poisoning if a prompt removal from the toxic environment is accomplished, together with proper medical treatment.

Abstract
Direct metal ligands to transition metals in metalloproteins exert a profound effect on protein-metal affinity and function. Indirect ligands, i.e., second-shell residues that hydrogen bond to direct metal ligands, typically exert more subtle effects on the chemical properties of the protein-metal complex. However, E117 of human carbonic anhydrase II (CAII), which is part of the E117-119-Zn(2+) triad, is a notable exception: E117-substituted CAIIs exhibit dramatically increased kinetics of zinc complexation, and the E117Q variant exhibits enormously diminished catalytic activity and sulfonamide affinity. The three-dimensional structures of zinc-bound and zinc-free E117Q CAII reveal no discrete structural changes in the active site that are responsible for enhanced zinc equilibration kinetics and decreased activity. Additionally, the structure of the acetazolamide complex is essentially identical to that of the wild-type enzyme despite the 10(4)-fold loss of enzyme-inhibitor affinity. We conclude, therefore, that the functional differences between E117Q and wild-type CAIIs arise from electrostatic and not structural differences in the active site. We propose that the E117Q substitution reverses the polarity of the residue 117-H119 hydrogen bond, thereby stabilizing H119 as a histidinate anion in the E117Q CAII holoenzyme. The additional negative charge in the first coordination sphere of the metal ion increases the pK(a) of the zinc-water ligand, destabilizes the transition state for CO(2) hydration, and facilitates the exchange of a zinc-histidine ligand with an additional water molecule by decreasing the stability of the tetrahedral zinc complex. These novel properties engineered into E117Q CAII facilitate the exploitation of CAII as a rapid and sensitive Zn(2+) biosensor.

Abstract
Chronic hypotension, volume nonresponsive, is not rare in hemodialysis patients and is usually refractory to various therapies. Midodrine hydrochloride is an alpha-mimetic drug acting directly on the peripheral alpha-receptor and increases blood pressure. We studied 10 uremic patients on hemodialysis with chronic hypotension to evaluate efficacy and safety of midodrine. Midodrine hydrochloride was administered at a dose of 2.5 mg twice on the dialytic day, 1.25 mg twice on the nondialytic day. Subjective symptoms and objective parameters were evaluated and compared before and after midodrine treatment. Midodrine significantly increased systolic pressure from 73.0 +/- 10.5 mm Hg to 90.5 +/- 12.3 mm Hg (p < 0.01); and diastolic blood pressure from 44.0 +/- 8.4 mm Hg to 55.4 +/- 7.9 mm Hg (p < 0.01) before dialysis. Orthostasis, dizziness, fatigue, blurred vision, dullness, headache, and depression improved an average of 62%. All patients tolerated midodrine treatment well. Only mild side effects were noted, including flush sensation, neck soreness, and headache. We conclude that midodrine may be another choice for uremic patients on hemodialysis with chronic hypotension which responds poorly to other conventional management.

Abstract
Five young infants with congenital rubella syndrome (CRS) underwent cranial ultrasonographic examinations and/or computed tomographic examinations. Only two of these infants were small for their gestational age, and none of them were microcephalic at birth. Deafness and ocular lesions were found in four patients, and congenital heart disease was found in three. All had abnormal ultrasonographic findings: linear-shaped hyperechogenicity over the basal ganglia was noted for five patients, periventricular punctate hyperechogenicity was noted for three, and subependymal cysts were observed in two. Follow-up ultrasonograms for two of the patients showed progressively enlarging hyperechogenic lesions. Calcification was found in both patients examined by means of computed tomography. All patients became microcephalic, with profound global developmental delay. Intracranial calcifications are common findings in patients with CRS. Ultrasonography should be performed for high-risk neonates, regardless of their symptoms. The finding of linear hyperechogenicity over the basal ganglia should prompt a search for all congenital infections, including CRS.

Abstract
Thirty-one patients (26 males, 5 females) with mean age 35 +/- 19 years (range 8 to 85 years) were diagnosed as non-traumatic rhabdomyolysis by clinical findings and elevation of serum creatine kinase (CK) between January 1989 and December 1993. Causes, laboratory measures, clinical courses, and outcome were reviewed retrospectively. Drug abuse, seizure, and excessive activity are the most common etiologies for non-traumatic rhabdomyolysis. Twelve patients presented with muscular pain and seven patients with muscle weakness. Twenty eight patients had urinalysis and five of them (18%) had negative orthotolidine dipstick test. Only seven patients (25%) were detected positive orthotolidine test without microscopic hematuria. Patients with acute renal failure had higher levels of potassium and uric acid. The patients who developed acute renal failure after admission had significantly higher levels of uric acid. The peak levels of CK did not correlate with development of acute renal failure. There was no episode of hyercalcemia. Seventeen patients (55%) had acute renal failure. Hemodialysis was required in nine cases. All survivors recovered with normal renal function except one who needed maintenance hemodialysis after two months follow-up. Two patients died of multi-organ failure and sepsis.

Abstract
Ninety-seven patients with urinary tract tuberculosis were reviewed from January 1983 to December 1993 at our hospital. Aside from two cases of military tuberculosis and three cases with coexisting active pulmonary tuberculosis, most urinary tract infections developed from a previous primary lung infection. Patients usually exhibited local symptoms. Fever, weight loss and anorexia were uncommon. Eighty-nine percent of the patients had abnormal urinalysis (hematuria and/or pyuria). Eight percent of the patients also had genital involvement, whereas 38% of these patients had normal intravenous pyelogram and urinalysis. Pyelograms disclosed abnormalities in 94% of the 97 patients and most revealed late changes, which were correlated with higher incidence of azotemia and anemia noted at diagnosis. Chemotherapy is the mainstay of treatment and at least three antituberculous drugs are required for initial therapy due to high drug resistance rate. Reconstructive surgery is warranted to salvage renal function. Except 6 patients run into maintenance hemodialysis, the renal functions of all patients remained stable during the period of follow-up, either receiving chemotherapy alone or combined surgery. Renal calcification may not represent inactive process, which requires further evaluation.

Abstract
To evaluate the characteristics of and acceptance by persons in Taiwan who currently use positive-pressure mechanical ventilation at home (HMV), a survey was conducted in August 1992 through home care and equipment providers to investigate these patients. The 34 cases enrolled, including 18 males and 16 females, were classified into four groups: (1) lung disease group (LD) (n = 7) including chronic obstructive pulmonary disease and bronchiectasis; (2) neuromuscular group (NM) (n = 14) including diverse neuromuscular diseases; (3) spinal disease group (SP) (n = 7) including spinal cord injuries or tumors and (4) unresponsive stroke group (US) (n = 6). The average age of the SP group was much younger than those of the other three groups. The duration of home ventilation was from 1 to 36 months, with a mean duration of 10.6 +/- 8.7 months. Fifteen cases had received HMV for more than one year. Twenty six (76.5%) of the patients were completely dependent. All of the US patients had to be ventilated all day long in contrast to 71.4% of LD completely dependent. The cost of the US group was higher than that of the other three groups. Two of the LD, five of NM and one US patient had been re-admitted because of pneumonia, tracheostomy wound infection, granulation formation or weaning problems before the study. A follow-up survey was done four months, then one year later. The survival rate was 16.7% for LD group, 50% for NM and US group. Of the SP group, all patients were surviving at the end of this study. Most of the present HMV users were satisfied with their setting. It was concluded that HMV is an acceptable alternative way of therapy for long-term ventilation patients in Taiwan. SP and NM patients are better candidates for HMV. The overall one year survival rate is promising, while SP patients had the best prognosis. Patients who had already used HMV for more than 11 months, regardless of the disease, have a better chance to live another year.

Abstract
Chest radiography, CT, and MR imaging were performed in a 3-year-old girl who had posterior mediastinal fibromatosis with transforaminal intraspinal and chest wall extension. Chest radiographs and CT scans showed a slow-growing, noncalcified but locally aggressive left paravertebral mass. The mass was slightly hyperintense relative to muscle on both T1-weighted and fast spin-echo T2-weighted MR images.
