The role of peripheral mononuclear cells (PMNC) was investigated in patients with hepatic fibrosis of chronic hepatitis or liver cirrhosis. PMNC from these patients released more fibroblast proliferating factor (FPF) in the conditioned medium than those PMNC from normal subjects in response to PHA stimulation. Production of FPF by PMNC from CAH patients was also observed in response to liver specific protein (LSP) which might act as a naturally occurring antigen in vivo. Analysis of FPF on gel permeation chromatography revealed two active components with molecular weight of 60000 (FPF-1) and 18000 (FPF-II). Both FPF-I and FPF-II exerted thymocyte proliferating activity, but not cytotoxic T cell line (CTLL) proliferating activity, indicating that they are closely related to interleukin-1 (IL-1). Isoelectrofocusing of FPF-I and FPF-II disclosed that each factor consisted of two peaks at similar pI: 5.3 and 7.0. Taking account of the fact the IL-1 consisted of two molecular forms of pI—5.4 (IL-1α) and 7.0 (IL-1β)—FPF-II is considered to be IL-1, which is a mixture of IL-1α and IL-1β, and FPF-I is probably the aggregated form of FPF-II. This assumption was further supported by the evidence that macrophages, which are the major source of IL-1 in patients with chronic hepatitis or liver cirrhosis, also released significantly higher amounts of FPF than those from normal subjects in response to stimulation by lipopolysaccharide. It was therefore concluded that in chronic hepatitis and liver cirrhosis, production of an IL-1, or a factor similar to IL-1, by PMNC is increased in response to mitogen or LPS. 相似文献

In the present investigation, a radioimmunoassay for carboxy terminal peptide of human type I procollagen (type 1 C-peptide) was developed. Its clinical implication for serodiagnosis of hepatic fibrosis in 85 patients with viral hepatitis, 45 patients with post-hepatitic liver cirrhosis and 37 patients with alcoholic liver diseases was evaluated in comparison with that of the previously established amino terminal peptide (type III N-peptide) assay. Anti-sera against type I procollagen was obtained by immunization of rabbit with purified type I procollagen from culture medium of IMR-90. The serum level of type I C-peptide in normal subjects was found to be 42 ng/ml (s.d. = 19). Type I C-peptide levels in patients with acute hepatitis were within normal range, while in chronic hepatitis, the mean type I C-peptide level increased as the grade of fibrosis advanced from grade I to III. However, there was no statistically significant difference between the mean type I C-peptide level of grade III and that of liver cirrhosis. Increments of type I C-peptide levels were also observed in alcoholic liver fibrosis (fatty liver with fibrosis and liver cirrhosis). On the other hand, type III N-peptide assay appeared to reflect not only the degree of hepatic fibrosis, but also the degree of hepatic inflammation, giving the high levels in acute viral hepatitis. Collectively, the results indicate the usefulness of type I C-peptide assay for monitoring hepatic fibrosis in viral hepatitis as well as in alcoholic liver disease. 相似文献

Measurements of serum levels of thyroxine (T4), free T4, 3,5,3'-triiodothyronine (T3), free T3, 3,3',5'-triiodothyronine (reverse T3, rT3), thyroxine-binding globulin capacity (TBGcap), chorionic gonadotrophin (hCG) and thyrotrophin (TSH) were carried out prospectively in eight women with uncomplicated pregnancies, in order to examine interrelationships between the thyroid gland and thyroid stimulating hormones during pregnancy. During pregnancy the levels of T4, free T4, T3, rT3 and TBGcap were significantly elevated, and TSH was decreased. It was noted that the elevation of T4 was maintained from the 8th to the 27th week of gestation while the level of TBGcap progressively increased. The levels of free T4 and rT3 in the first and third trimesters were significantly higher than those of age-matched, non-pregnant women. The levels of hCG showed a biphasic variation, with a peak in the 8th to 15th weeks, followed by a decline in the second trimester and a small, secondary elevation in the 32nd to 39th weeks. This later elevation was positively correlated with changes in free T4 and free T3 levels. The increase of serum T4 accompanied by an increase of free T4 in the first trimester appeared due to augmented secretion of T4, rather than being secondary to the elevated levels of TBGcap. 相似文献

In an initial study, three groups of patients with Kawasaki disease received either aspirin alone or alkylated immunoglobulin G intravenous preparation (IGIV) 200 mg/kg daily x3 days + aspirin, or 400 mg/kg alkylated IGIV daily x3 days + aspirin. In a second study, three groups of patients were treated with either 100, 200 or 400 mg/kg of native IGIV in combination with aspirin daily for 5 days. While the regimen of 200 mg/kg native IGIV daily x 5 days was found to be effective, the incidence of coronary artery lesions (CAL) was even less on a regimen of 400 mg/kg daily x 5 days. It is therefore suggested that a better therapeutic effect can be achieved with a 400 mg/kg dose of native IGIV. Based on the results from these two studies, it is assumed that native IGIV is more effective in inhibiting CAL formation and persistence than the chemically modified preparation in which the biological activity of the Fc region in the immunoglobulin G molecule is altered. 相似文献

Purpose
Approximately 15 to 20% of infertile men have azoospermia. In the Y chromosome a deletion, termed the azoospermic factor, has been found in some cases of idiopathic azoospermia. We investigate the relationship of factors in autosomal chromosomes (HLA class I antigens) to spermatogenesis failure in idiopathic azoospermia.Materials and Methods
We evaluated 65 infertile Japanese men with idiopathic azoospermia. The frequency of the HLA allele reported in 1,216 healthy Japanese men was used as a control. HLA class I typing was performed by the National Institutes of Health standard serological method or polymerase chain reaction-sequence specific primer analysis. Allele frequencies were calculated. We determined statistical significance in the frequency of each allele in patients and controls using the chi-square test. The relationship of HLA antigens to idiopathic azoospermia was expressed as relative risk.Results
In Japanese men with idiopathic azoospermia the frequency of HLA-A33, B13 and B44 was significantly increased compared with controls. The relative risk of HLA-B44 was 8.4, an extremely high value compared with that of other diseases and HLA antigens.Conclusions
We suggest that HLA class I antigens are important genetic markers that represent a risk factor for idiopathic azoospermia. 相似文献27.

Abstract— The anti-inflammatory profile of dihemiphthalate compounds of glycyrrhetinic acid derivatives in acute rat paw oedema induced by various vasoactive agents was compared with the parent compound. Three dihemiphthalate compounds (the di-sodium salt of 18 β-olean-12-ene-3β,30-diol di-O-hemiphthalate, 18β-olean-9(11),12-dione-3β,30-diol di-O-hemiphthalate and olean-11,13(18)-diene-3β,30-diol di-O-hemiphthalate), significantly inhibited development of carrageenan-induced rat paw oedema during the first 3 h (ED50 70, 90, and 108 mg kg?1 respectively, p.o.), while glycyrrhetinic acid (ED50, 200 mg kg?1) showed a significant inhibition of paw oedema 3 h after carrageenan treatment. The dihemiphthalate compounds also suppressed mouse paw oedema induced by histamine, bradykinin, and PAF acether at doses of less than 100 mg kg?1. However, these compounds failed to inhibit 5-HT-induced mouse paw oedema. Glycyrrhetinic acid had little effect on mouse paw inflammation induced by the above irritants. The three compounds at 10?7-10?4 m , inhibited histamine-induced contraction of guinea-pig isolated ileum. However, concentration-response curves to 5-HT and bradykinin were not affected by the same compounds. These results suggest that the dihemiphthalate compounds modulate vascular permeability caused by endogenous vasoactive agents as one of the anti-inflammatory mechanisms. This action is quite different from that of glycyrrhetinic acid. 相似文献

J Wave Syndromes . Introduction: Recently, great attention has been paid to the risk stratification of asymptomatic patients with an electrocardiographic early repolarization (ER) pattern. We investigated several repolarization parameters including the Tpeak‐Tend interval and Tpeak‐Tend/QT ratio in healthy individuals and patients with J wave syndrome who were aborted from sudden cardiac death. Methods and Results: Ninety‐two subjects were enrolled: 12 patients with ventricular fibrillation associated with J waves, 40 healthy subjects with an uneventful ER pattern and 40 healthy control subjects (C) without any evident J waves. Using ambulatory electrocardiogram recordings, the average QT interval, corrected QT interval (QTc), Tpeak‐Tend (Tp‐e) interval, which is the interval from the peak to the end of the T wave, and Tp‐e/QT ratio were calculated. Using ANOVA and post hoc analysis, there was no significant difference in the average QT and QTc in all 3 groups (QT; 396 ± 27 vs 405 ± 27 vs 403 ± 27 m, QTc; 420 ± 26 vs 421 ± 21 vs 403 ± 19 milliseconds in the C, ER pattern and J groups, respectively). The Tp‐e interval and Tp‐e/QT ratio were significantly more increased in the J wave group than the ER Pattern group (Tp‐e: 86.7 ± 14 milliseconds vs 68 ± 13.2 milliseconds, P < 0.001, Tp‐e/QT; 0.209 ± 0.04 vs 0.171 ± 0.03, P < 0.001), but they did not significantly differ between the C and ER pattern groups (Tp‐e: 68.6 ± 7.5 vs 68 ± 13.2, P = 0.97, Tp‐e/QT 0.174 ± 0.02 vs 0.171 ± 0.03, P = 0.4). Conclusion: As novel markers of heterogeneity of ventricular repolarization, Tpeak‐Tend interval and Tp‐Te/QT ratio are significantly increased in patients with J wave syndromes compared to age and sex‐matched uneventful ER.
