Clinical and pathologic findings of avian paramyxovirus type 1 (PMV-1) in 19 houbara bustards (Chlamydotis undulata macqueenii) imported from Pakistan into the United Arab Emirates and one captive-bred bird are reported. Clinical signs included circling, walking backward, ataxia, opisthotonos, torticollis, recumbency, head tilt, head shaking, head tremor, tucking of head under keel, nasal discharge, conjunctivitis, and diarrhea. The length of time imported birds exhibited clinical signs varied from 4 days to 18 mo after importation. Hemagglutinating antibodies against PMV-1 were detected in the sera of all 17 birds from which blood samples were collected, and PMV-1 was isolated from pooled brain, spleen, and lung tissues from two birds with acute clinical signs. There were no distinctive gross lesions at necropsy, and histologic findings were consistent with but not pathognomonic for PMV-1. All houbara bustards managed in a captive breeding and restoration program established by the National Avian Research Center have been vaccinated against PMV-1 since October 1992, and no case of PMV-1 has been reported in this collection since that time.

Eighty-four adult patients were recruited from four centres in Spain to evaluate the efficacy and safety of low-dose (0.1 mg/kg per day) oral tacrolimus plus corticosteroid immunosuppression in liver transplantation. The median daily dose of tacrolimus was increased during the first 3 weeks of therapy from an initial dose of 0.1 mg/kg per day to a maximum of 0.145 mg/kg per day and was subsequently decreased gradually to a minimum of 0.076 mg/kg per day at 1 year. At 7 days posttransplantation, 87.7% of patients had trough whole blood levels of tacrolimus within the therapeutic range (5-20 ng/ml), and the median levels remained fairly constant during the rest of the year (10.1-11.8 ng/ml). None of the patients required intravenous administration of tacrolimus. At 1 year, Kaplan-Meier estimates showed that 73.8% of the patients were receiving tacrolimus monotherapy without the need for corticosteroids. One-year patient and graft survival were 75.9% and 72.3%, respectively. The incidence of acute rejection was 51.2%; 9.5% of cases resolved spontaneously without antirejection therapy and 10.7% were corticosteroid resistant. Only 1 patient (1.2%) developed chronic rejection. The most important adverse events were hypertension (45.2%), tremor (44.0%), diabetes mellitus (33.3%), diarrhoea (31%) and nephrotoxicity (29.8%). Severe neurotoxicity-like convulsions (4.8%), dysarthria (9.5%), delirium (1.2%), coma (1.2%) and the need for haemodialysis (3 patients) were uncommon. In conclusion, low-dose oral tacrolimus immunosuppression is associated with low toxicity without compromising efficacy.

Border disease (BD) is a congenital virus disease of sheep and goats first reported in 1959 from the border region of England and Wales. BD virus (BDV) is a pestivirus in the genus Flaviviridae and is closely related to classical swine fever virus and bovine virus diarrhoea virus (BVDV). Nearly all isolates of BDV are non-cytopathogenic (ncp) in cell culture. There are no defined serotypes but pestiviruses isolated from sheep exhibit considerable antigenic diversity and three distinct antigenic groups have been identified. Distribution of the virus is worldwide. Prevalence rates vary in sheep from 5 to 50% between countries and from region-to-region within countries. The disease in goats is rare and characterized by abortion. Clinical signs in sheep include barren ewes, abortions, stillbirths and the birth of small weak lambs. Affected lambs can show tremor, abnormal body conformation and hairy fleeces (so-called 'hairy-shaker' or 'fuzzy' lambs). Vertical transmission plays an important role in the epidemiology of the disease. Infection of fetuses can result in the birth of persistently infected (PI) lambs. These PI lambs are viraemic, antibody negative and constantly excrete virus. The virus spreads from sheep to sheep with PI animals being the most potent source of infection. Apparently healthy PI sheep resulting from congenital infection can be identified by direct detection of viral antigen or viral RNA in leukocytes or by isolation of ncp virus from blood or serum in laboratory cell cultures. Isolation of virus is unreliable in lambs younger than 2 months old that have received colostral antibody. The isolation of virus from tissues of aborted or stillborn lambs is difficult but tissues from PI sheep contain easily detectable levels of virus. To detect the growth of virus in cell cultures it is essential to use an immune-labelling method. Acute infection is usually subclinical and viraemia is transient and difficult to detect. Sheep may also be infected following close contact with cattle excreting the closely related BVDV.

The present study assessed the ability of various site-selective N-methyl-D-aspartate (NMDA) receptor antagonists to affect the discriminative stimulus properties of naloxone in morphine-dependent rats. Adult male Wistar rats were trained to discriminate 0.1 mg/kg of s.c. naloxone from saline using a Y-maze shock-avoidance procedure. Naloxone-appropriate responding was exhibited as a function of naloxone dose (0.01-1.0 mg/kg, ED50 = 0.03 mg/kg) and was also observed when morphine treatment temporarily was discontinued (8-96 hr, peak at 24 hr). Discriminative stimulus effects of naloxone (0.1-3.0 mg/kg) were antagonized by morphine (10-100 mg/kg). Ligands of peripheral opioid receptors failed to either substitute for naloxone (methylnaloxone, 0.1-3.0 mg/kg) or attenuate naloxone's stimulus effects (loperamide, 1-30 mg/kg). In rats treated with the training dose of naloxone, administration of dizocilpine (0.03-0.3 mg/kg) and D-CPPene (1-10 mg/kg) decreased levels of naloxone-appropriate responding, whereas memantine (1-30 mg/kg), ACEA-1021 (10 and 50 mg/kg) and eliprodil (3-30 mg/kg) seemed to have little or no effects. Meanwhile, all NMDA receptor antagonists produced a decrease in the occurrence of two or more of the following opioid withdrawal signs: weight loss, forelimb tremor, ptosis, diarrhea and "wet-dog"-like shaking. Additionally, dizocilpine (0.1 mg/kg), D-CPPene (5.6 mg/kg) and ACEA-1021 (50 mg/kg) but not memantine (10 mg/kg) or eliprodil (30 mg/kg) significantly reduced the naloxone-appropriate escape area selection when administered during the period of suspended morphine treatment 24 hr after the last morphine injection. Thus, NMDA receptor antagonists appear to inhibit the discriminative stimulus effects of both naloxone-precipitated and spontaneous morphine withdrawal, and this ability depends on the type of antagonist applied.

An 82-year-old man was admitted because of abdominal pain and a shaking chill. His medical history revealed ileocecal resection because of ileitis associated with a Yersinia infection 3 years before admission. One year later he was readmitted because of bowel obstruction due to recurrent ileitis. He was treated with trimethoprim-sulfamethoxazole for two weeks because of positive serological tests for Yersinia and made a full recovery except for chronic diarrhoea. On the current admission, stool cultures yielded Campylobacter upsaliensis. Further analysis showed severe non-specific ulcerative ileitis without colitis. A diagnosis of Crohn's disease was made. The patient was treated with prednisone and mesalazine and made a full recovery. The chronic diarrhoea disappeared. The course was complicated by a cerebro-vascular thrombosis and severe thrombocytosis due to polycythaemia vera. Treatment with hydroxyurea was effective in lowering the thrombocyte count.

Four Merino lambs were intranasally inoculated with bovine herpesvirus type 5 (BHV-5) reference strain N569. Two lambs were mock-inoculated as negative controls. The virus-inoculated animals developed apathy, inappetence, rhinitis, nasal, ocular and genital discharge, slight diarrhea and neurological disorders, like tremor and salivation. BHV-5 was isolated from the nasal discharge in two of the animals, while the polymerase chain reaction (PCR) detected the virus in all the infected lambs. Two lambs died on post infection day (PID) 13, while the other two infected animals were euthanized on PID 15 and 30. Gross pathological changes were not observed, however, histopathological examinations revealed diffuse nonsuppurative meningo-encephalitis in all infected animals. Viral antigen was detected by immunohistochemistry and viral nucleic acid was revealed by in situ hybridization in the brain of the two lambs, which died on PID 13. The virus was demonstrated by virus isolation and by PCR from different organs of all the infected animals. Slight rise of antibodies was observed in the infected animals from PID 15. The results show that BHV-5 is able to cross the species barrier and may establish infection in sheep.

Our previous report suggested that antagonists acting at NMDA receptors attenuate discriminative stimulus effects of naloxone in morphine dependent rats. Nitric oxide (NO) is a putative second messenger which mediates NMDA receptor activation. The present study evaluated behavioral effects of NO synthase inhibitor, 7-nitroindazole in morphine-dependent rats trained to discriminate 0.1 mg/kg naloxone from saline. 7-Nitroindazole did not significantly affect naloxone's discriminative stimulus effects but decreased naloxone-induced weight loss and abolished expression of several withdrawal signs--diarrhea, scream on touch, tremor and 'wet dog'-like shaking suggesting different mechanisms for subjective and somatic components of opioid withdrawal.

A previously healthy 15-year-old female was admitted to our hospital complaining of nausea and vomiting. She did not complain of diarrhea. A physical examination revealed a lower right quadrant abdominal tenderness without rebound or spontaneous pain and a knocking pain of the costovertebral angle. A high fever, knocking pain of costovertebral angle, and urinary findings including Gram's stain, lead us to suspect a urinary tract infection, cefotiam was administered intravenously. Spiking fever with shaking chills continued for three days, and three sets of blood cultures were positive for Salmonella Oranienburg, but her urine culture was negative. Her history was taken again, revealing an intake of a processed squid product. The product was confirmed by the local public health center to be Salmonella Oranienburg. Finally food poisoning by Salmonella Oranienburg with sepsis was diagnosed. With cefotiam she became better and was discharged from the hospital on the 10th hospital day. During admission to the hospital she did not experience any diarrhea, and her stool culture was negative. Epidemics of Salmonella Oranienburg food poisoning are relatively rare in the literature. In Japan, one has arisen as a result of contamination of a processed squid product in March 1999. However, there have been no cases without so-called gastroenteritic symptoms (abdominal pain and diarrhea) who were previously healthy and developed sepsis caused by Salmonella Oranienburg, reported in Japan. Even in previously healthy patients, with an epidemic situation of non-typhoidal salmonellosis, salmonella sepsis must be ruled out. Among such cases, those who present with spiking fever and shaking chills should be given antibiotic therapy after taking appropriate cultures.

Vibrio cholerae WO7 (serogroup O1) isolated from patients with diarrhea produces an extracellular toxin despite the absence of ctx, zot, and ace genes from its genome. The toxin elongates Chinese hamster ovary cells, produces fluid accumulation in ligated rabbit ileal loops, and agglutinates freshly isolated rabbit erythrocytes. Maximal production of this toxin (WO7 toxin) was seen in AKI medium with the pH adjusted to 8.5 at 37 degrees C under shaking conditions. We purified this toxin to homogeneity by sequential ammonium sulfate precipitation, affinity chromatography using a fetuin-Sepharose CL-4B column, and gel filtration chromatography, which increased the specific activity of the toxin by 1.6 x 10(6)-fold. The toxin is heat labile and sensitive to proteases and has a subunit structure consisting of two subunits with molecular masses of about 58 and 40 kDa as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Agglutination of GM1-coated sheep erythrocytes by toxin suggests that GM1 might be the physiologic receptor for WO7 toxin on the enterocytes. An immunodiffusion test between the antiserum raised against the purified WO7 toxin and the purified toxin gave a well-defined precipitation band. In the immunoblot assay, two bands were observed in the 58- and 40-kDa region. At the same time, antiserum against WO7 toxin failed to show any cross-reactivity with cholera toxin or Escherichia coli heat-labile toxin (LT1) in an immunodiffusion test or immunoblot assay. The enterotoxic activity of WO7 toxin could be inhibited by antiserum against purified WO7 toxin. Our results indicate that WO7 toxin is structurally and functionally distinct from other cholera toxins and that the enterotoxic activities expressed by WO7 toxin appear to contribute to the pathogenesis of disease associated with V. cholerae O1 strains.

We report a 73-year-old Japanese woman with familial Parkinson's disease. The patient was well until her 67 years of the age, when she noted rest tremor in her right hand. Soon after her gait became short stepped. She visited our clinic on October 6, 1992 when she was 68 years old. She was alert and well oriented without dementia. She showed masked face, small voice, small stepped gait, retropulsion, resting tremor in her right hand, rigidity in the neck, and bradykinesia. She was treated with 400 mg/day of levodopa-carbidopa, which improved her symptoms, however, she developed wearing off phenomenon 3 years after the initiation of levodopa treatment. On August 26, 1998, she developed abdominal pain, diarrhea, and vomiting. She was admitted to another hospital, where abdominal plain x-ray revealed an evidence of intestinal obstruction (ileus). She was treated with nasogastric suction and intravenous fluid. Her condition did not improve and she was transferred to our hospital on August 29, 1998. Her family history revealed no consanguineous marriage. She had two elder brothers and three elder sisters. One of her brothers had been diagnosed as Parkinson's disease. Her husband also suffered from Parkinson's disease, however, her parents apparently did not have Parkinson's disease. On admission, she appeared to be drowsy. Her blood pressure was 102/70 mmHg, body temperature 36.2 degrees C. The lungs were clear and no cardiac murmur was present. Abdomen was flat and bowel sound was audible. No abnormal mass was palpable. Neurologic examination revealed mild consciousness disturbance, masked face, and small voice. No motor paralysis was noted. Muscle tone was hypotonic. No abnormal involuntary movement was noted. Abnormal laboratory findings on admission were as follows; WBC 11,300/microliter, amylase 1,373 IU/l, CK 446 IU/l, BUN 50 mg/dl, creatinine 1.17 mg/dl, CRP 22.7 mg/ dl, Na 134 mEq/l, K 3.1 mEq/l, and Cl 81 mEq/l. A chest x-ray film revealed pneumonic shadows in both lower lung fields. She was treated by nasointestinal suction, intravenous fluids, and chemotherapy for her infection. Her BP started to drop on September 2 and she developed cardiac arrest on the same day. She was discussed in a neurological CPC. The chief discussant arrived at the conclusion that the patient had a form of autosomal dominant familial Parkinson's disease. As parents did not have Parkinson's disease, some of the participants raised the possibility of autosomal recessive inheritance. But the age of onset was too late for autosomal recessive inheritance. Majority thought that the mode of inheritance was autosomal dominant with low penetrance. alpha-Synuclein mutation causes an autosomal dominant familial Parkinson's disease, but this type is very rare in non-Greek populations and the penetrance is high. Chromosome 2-linked autosomal dominant familial Parkinson's disease shows low penetrance. There are many other autosomal dominant forms of familial Parkinson's disease linked to yet unknown chromosome loci. Majority thought that this patient also had a form of Lewy-body positive autosomal dominant familial Parkinson's disease of unknown chromosome locus. Post mortem examination revealed ischemic intestinal lesion with strangulation. This was thought to be the cause of her death. In the central nervous system, the brain appeared to be normal by inspection. In the coronal sections, the substantia nigra and the locus coeruleus showed marked depigmentation. Histologic examination revealed marked neuronal loss and Lewy body formation in the remaining neurons. Pathologic examination was consistent with Parkinson's disease. Mutational analysis for the parkin gene was negative.
