Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

BACKGROUND: The purpose of this study was to investigate the mechanism of endothelium-dependent and independent responses to endothelins (ETs) in porcine coronary artery. METHODS: The vascular rings of left anterior descending artery or left circumflex artery from 7 pigs were suspended in conventional organ chambers for the measurement of isometric force. To evaluate relaxation responses, vascular rings with endothelium were exposed to ET-1 and ET-3. To evaluate contraction responses, vascular rings with and without endothelium were exposed to ET-1 and ET-3 in the presence or absence of BQ 123 (ET(A) receptor antagonist) or TAK-044 (ET(A) and ET(B) receptor antagonist). RESULTS: Transient relaxation responses of vascular rings occurred after exposure of ET-1 and ET-3. These transient responses disappeared after preincubation with N-nitro-L arginine. There was an increased contractions of vascular rings according to increasing concentration of ET-1 and ET-3. The initial responses were enhanced in vascular rings without endothelium in ET-1 and ET-3. In vascular rings with endothelium, the contraction responses were more reduced in vascular rings with preincubation of BQ 123 than in vascular rings without BQ 123 in ET-1. In vascular rings without endothelium, the contraction responses were more reduced in vascular rings with preincubation of TAK-044 than in vascular rings without TAK-044 in ET-1. CONCLUSION: ET(B) receptor on the endothelium might mediate the transient vasodilator responses to ET-1 and ET-3 through release of nitric oxide in porcine coronary artery. ET(A) and ET(B) receptor on vascular smooth muscle cells might mediate vasoconstrictor responses to ETs.

Laparoscopy is a frequently used technique in surgery and gaining wide popularity replacing laparotomy. The advantages of laparoscopy are shorter hospital stay, faster recovery, more decreased postoperative pain and smaller scar than laparotomy. But inducing artificial pneumoperitoneum with gas causes various complications. Among them, gas embolism is a rare but fatal complication and may occur more frequently when laparoscopy is performed simultaneously with hysteroscopy. We experienced one case of gas embolism during diagnostic laparoscopy for secondary infertility and hysteroscopic resection of uterine myoma under general anesthesia. Early diagnosis and prompt treatment seem to be the keys to prevent catastrophic outcome and the anesthesiologist should know about it's patho- physiology, preventive methods, diagnosis and treatment.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or Agglutination Tests ; Animals ; Bacterial Vaccines/administration & dosage ; Cattle ; Cattle Diseases/immunology/microbiology ; Female ; Mastitis, Bovine/*microbiology ; Polysaccharides, Bacterial/*classification/isolation & purification ; Serotyping/methods/veterinary ; Staphylococcal Infections/immunology/*veterinary ; Staphylococcus aureus/*classification/*immunology/isolation & purification

PURPOSE: The detection of epileptogenic lesion plays an important role in the management of patients with partial epilepsy. Although the development of MRI improved the examination of cerebral hemispheres greatly, many patients with neocortical temporal lobe epilepsy (TLE) or extratemporal lobe epilepsy (extra-TLE) still show no lesion in conventional two-dimensional (2D) images. To increase the yield of MRI in those patients, we performed three-dimensional (3D) surface-projection rendering (SPR) of the cerebral hemispheres. METHODS: Conventional 2D MRI (T1, T2, FLAIR, thin slice SPGR) and 3D SPR were performed in 24 patients with neocortical TLE and extra-TLE, and 20 normal subjects. Sulcogyral patterns were evaluated blindly to clinical information. The locations of the epileptogenic zone, ictal onset zone (IOZ) and irritative zone (IRZ) were determined by intracranial EEG monitoring and epilepsy surgery. RESULTS: The 2D MRI identified epileptogenic lesions in five of the 10 neocortical TLE (50%) and five of the 14 extra-TLE (35.7%). 3D SPR revealed abnormal sulcogyral patterns in 9 of the 10 neocortical TLE (90%) and 9 of the 14 extra-TLE (64.3%). Cortical deformation zones with sulcogyral anomalies included the whole area of IOZ in 10 (55.5%) and IRZ in 6 (33.3%), overlapped with IOZ in 7 (38.9%) and IRZ in 11 (61.1%), were connected to IOZ in 1 (5.6%) and IRZ in 1 (5.6%). CONCLUSION: 3D SPR of volumetric MRI data can detect epileptogenic structural lesions of neocortical epilepsy that are not visible in the conventional 2D images.
