Abstract: The case of a 59 year-old female with asymptomatic primary biliary cirrhosis with negative anti-mitochondrial antibody is presented. According to the results of the first laparoscopy and liver biopsy, reddish patch was observed but chronic non-suppurative destructive cholangitis could not histologically be confirmed. A follow-up laparoscopy with liver biopsy conducted 39 months after the first laparoscopy revealed progress in the laparoscopic findings, i. e. a focal appearance of mesh-like white marking and undulation, when chronic non-suppurative destructive cholangitis was histologically demonstrated. Following the diagnosis of primary biliary cirrhosis, ursodeoxycholic acid treatment was begun, and the patient's serum levels of transaminases and biliary tract enzymes showed a rapid improvement. The importance of a laparoscopy with liver biopsy for the diagnosis of asymptomatic primary biliary cirrhosis in a case with negative anti-mitochondrial antibody is emphasized, and the follow-up of such a case discussed. 相似文献

A heptadecapeptide has been isolated from a side fraction of β-MSH in an acid acetone extract of the pituitary of the salmon, Oncorhynchus keta. The sequence analysis revealed the peptide to be another form of salmon β-MSH with following primary structure; H-Asp-Gly-Ser-Tyr-Arg-Met-Gly-His-Phe-Arg-Trp-Gly-Ser-Pro-Thr-Ala-Ile-OH. The findings of two distinctive β-MSHs as well as two endorphins as reported previously in the pituitary extract suggest that the teleost pituitary may secrete two different precursor molecules, β-LPH, and thus also higher molecular weight precursors. 相似文献

A new devised arginine derivative, NG-mesitylene-2-sulfonylarginine, Arg(Mts), was employed for the synthesis of hypothalamic substance P and neurotensin. The former was obtained in 74% yield by treatment of the protected undecapeptide amide, Z - Arg(Mts) - Pro - Lys(Z) - Pro - Gln - Gln - Phe - Phe - Gly - Leu - Met(O)-NH2, with methanesulfonic acid in the presence of anisole followed by reduction of the sulfoxide with 2-mercaptoethanol. The latter was obtained in 54% yield by the similar treatment of the protected tridecapeptide ester, Z-Pyr-Leu - Tyr - Glu(OBzl) - Asn - Lys(Z)-Pro-Arg(Mts) - Arg(Mts) - Pro - Tyr-Ile-Leu-OBzl, with methanesulfonic acid. As scavenger, a mixture of anisole-thioanisole-o-cresol (1:1:1, by vol.) was employed to suppress the side reaction, O-mesitylene-2-sulfonation of the Tyr residue. 相似文献

A novel peptide antibiotic, K-582, which exhibited significant growth inhibition of Candida, viruses and ascites tumor in mice, was found in the culture medium of a strain of Metarhizium anisopliae by Kondo et al. (J. Antibiotics 33 , 535–542 (1980)]. K-582 consisted of two components, designated K-582 A and K-582 B. Threonine, tyrosine, ornithine, and an unusual amino acid were common in both peptides, but lysine was an extra component of K-582 A. The unusual amino acid was identified to be threo-γ-hydroxy-L-arginine (OHArg) by means of mass, nuclear magnetic resonance and infrared spectrometries of the derivatives and the related compounds. The threonine and the arginine were assigned to be L-configuration, and the ornithine and the tyrosine to be D-configuration in both K-582 A and K-582 B, and the lysine to be L-configuration by comparison of their optical rotatory dispersion spectra with those of standard amino acids. The elucidation of primary structure revealed that they were closely related heptapeptides with the following sequence: K-582 A:H-Arg-OHArg-Orn-Thr-Orn-Lys-Tyr-OH; K-582 B:H-Arg-OHArg-Orn-Thr-Orn-OHArg-Tyr-OH, and had the identical sequence in terms of the configuration of their constituents, namely L-L-D-L-D-L-D. 相似文献

Aims: The His bundle electrogram is believed to reflect the exact location of the His bundle. However, the distinction between distal His bundle potential and proximal right bundle branch potential is challenging. The aim of this study was to pinpoint the location of the branching point of the His bundle, and to compare that site with the site of recording of the largest His bundle electrogram (LH) during sinus rhythm.
Methods: We hypothesized that the site of earliest His activation (EH) during retrograde conduction via the left bundle branch is the branching point. We studied 15 nonconsecutive patients (mean age = 40 ± 22 years; eight men). We performed a programmed stimulation from right ventricular apex until retrograde right bundle branch block appeared. At that point we measured (1) the distance between antegrade LH site and retrograde EH site and (2) the atrial-to-ventricular amplitude ratio (A/V ratio) at both sites.
Results: EH was recorded at the proximal electrode of the His bundle catheter in all patients. Mean distance between EH and LH was 9.8 ± 2.5 mm. The mean A/V ratios at the EH site and the LH site were 1.01 ± 0.42 and 0.08 ± 0.06, respectively.
Discussion: This study showed that the EH site is located approximately 10-mm proximal to the LH site. The mean A/V ratio at the EH site during sinus rhythm is approximately 1.0. These observations suggest that the majority of His potentials reflect proximal right bundle activation. Before delivering radiofrequency energy in the para-Hisian area, attention should be paid to the presence of a His potential and to the A/V ratio, rather to the amplitude of the His electrogram. 相似文献

Vasospasm, initial neurological damage, rebleeding, and periprocedural complications are associated prognostic factors for clinical outcomes after aneurysmal subarachnoid hemorrhage (SAH). In this study, factors related to delayed ischemic neurological deficit (DIND) are evaluated using data from our institute for the last 18 years. Data from 2001 to 2018 of patients with aneurysmal SAH who underwent surgical clipping (SC) or endovascular coiling (EC) within 7 days of onset were retrospectively analyzed. Cases of mortality within 5 days after treatment were excluded. Multivariate analysis was used to identify the risk factors for DIND. In total, 840 cases of SAH were assessed; among these cases, 384 (45.7%) and 456 (54.3%) were treated with SC and EC, respectively. The frequency of DIND in the EC group was significantly less than that in the SC group (11.8% vs. 17.7%; p = 0.016). In the results of multivariate analysis, internal carotid artery (ICA) aneurysm and hemorrhagic complications were the risk factors for DIND. Cilostazol administration and EC were significant factors for vasospasm prevention after aneurysmal SAH (odds ratio of ICA aneurysm: 1.59, hemorrhagic complications: 1.76, SC: 1.51, and cilostazol administration: 0.51, respectively). Cilostazol administration was also a significant factor in patients who were treated with EC. ICA aneurysm, treatment strategy, hemorrhagic complications, and cilostazol administration were associated with DIND. Oral administration of cilostazol and avoiding hemorrhagic complications were effective in DIND prevention. If both treatments are available for ruptured aneurysms, clinicians should choose EC on the basis of its ability to prevent DIND. 相似文献

To assess the characteristics of intrahepatic metastatic lesions (IML) in hepatocellular carcinoma (HCC), we analysed both the histological features and proliferative activities of 15 resected cases of HCC accompanied by IML. The histological features of the IML were essentially the same as those observed in the main nodules in 12 (80%) of 15 cases. In 13 (87%) of 15 cases, the labelling index of proliferating cell nuclear antigen (PCNA) in the IML was either higher than or the same as in the main nodules. In 10 (77%) of 13 cases, the MIB-1 labelling index in the IML was either higher than or the same as in the main nodules. The results indicate that the histological features of the IML are essentially the same as those of the main nodules, while the proliferative activities in the IML were generally higher than those in the main nodules. Such characteristics may thus provide a clue to help distinguish intrahepatic metastasis from the multicentric occurrence of HCC. 相似文献
