Soluble human MHC class I molecules induce soluble Fas ligand secretion and trigger apoptosis in activated CD8(+) Fas (CD95)(+) T lymphocytes.

In the present study, we have evaluated the apoptotic effect of soluble human MHC class I (sHLA-I) antigens on CD8(+) T lymphocytes. sHLA-I antigens and beta(2)-microglobulin-free HLA class I heavy chains, isolated from serum, induced apoptosis on phytohemagglutinin-activated CD8(+) T lymphocytes in autologous and allogeneic combinations. The extent of CD8(+) T cell apoptosis depends on the degree of activation, time of incubation with sHLA-I antigens and amount of sHLA-I antigens added to the cultures. Apoptosis is induced by the interaction of Fas (CD95)(+) cells with soluble Fas ligand which is released following binding of sHLA-I antigens to CD8 molecules. These results suggest that sHLA-I antigens may regulate immune responses by inducing apoptosis in activated CD8(+) T cells.

Soluble intercellular adhesion molecule-1 (sICAM-1) and soluble interleukin-2 receptors (sIL-2R) in scleroderma skin.

In order to investigate whether soluble intercellular adhesion molecule-1 (sICAM-1) and soluble interleukin-2 receptors (sIL-2R) were present in scleroderma skin, and to compare their levels to concentrations measured in plasma and clinical parameters, we examined suction blister fluid and plasma from 13 patients with systemic sclerosis and 11 healthy volunteers. Suction blisters and biopsies were from the transition zone between normal skin and scleroderma, and uninvolved abdominal skin. The levels of sICAM-1 and sIL-2R were significantly increased in both plasma and suction blister fluid from systemic sclerosis patients compared with healthy volunteers. ICAM-1 was localized to vessels and perivascular mononuclear infiltrates by immunohistochemical methods. IL-2R was expressed by CD3-positive cells. The elevated levels of sICAM-1 and sIL-2R in suction blister fluid point towards activation of endothelial cells and T cells in both the transition zone and uninvolved skin of systemic sclerosis patients.

Soluble interleukin-2 receptor and soluble CD8 in liver cirrhosis and obstructive jaundice.

Activated lymphocytes secrete soluble interleukin-2 receptor (sIL-2R); CD8-positive lymphocytes secrete soluble CD8 (sCD8). Liver dysfunction in cirrhosis and obstructive jaundice is known to result in depressed cellular immunity. To evaluate whether this is due to real inactivation of the immune system, we measured sIL-2R and sCD8 in the serum of 46 patients with liver cirrhosis, 25 patients with obstructive jaundice, 32 patients with alcoholic liver disease without evidence of cirrhosis, 23 healthy persons and 43 patients with unrelated disease. sIL-2R in patients with cirrhosis (mean +/- s.e.m. 1499 +/- 140 U/ml) and obstructive jaundice (1517 +/- 204) was significantly increased compared with healthy subjects (363 +/- 29) and patients with unrelated diseases (685 +/- 92); sCD8 was significantly increased in patients with cirrhosis (737 +/- 63) but not in patients with obstructive jaundice (419 +/- 32) compared with healthy subjects (322 +/- 23) and patients with unrelated diseases (375 +/- 22). No difference was found between patients with cirrhosis due to alcohol abuse (n = 15) and chronic hepatitis B (n = 6). The Child-Pugh score had no significant influence on the sIL-2R or sCD8 value. In obstructive jaundice, sIL-2R correlated with alkaline phosphatase as marker of cholestasis (r = 0.43). These data show that in spite of the apparent depressed cellular immune defense both in liver cirrhosis and obstructive jaundice there is a general activation of the immune system but the CD8+ cell compartment is only activated in liver cirrhosis. The great changes of sIL-2R and sCD8 in liver dysfunction are important for the interpretation of studies using these serum proteins as markers for immune activation.

Use of an alkali-soluble water-soluble extract of Blastomyces dermatitidis yeast-phase cell walls and isoelectrically focused components in peripheral lymphocyte transformations.

An alkali-soluble water-soluble extract of Blastomyces dermatitidis yeast-phase cell walls was tested for its ability to elicit a response in lymphocytes isolated from the peripheral blood of Blastomyces-infected guinea pigs. Sequential preparations of the antigen were reproducible and specific in the in vitro lymphocyte transformation assay. Cross-reactivity of the antigen was not evident in lymphocyte transformation assays on lymphocytes obtained from Histoplasma-infected guinea pigs or from animals sensitized with complete Freund adjuvant. Fractionation of the antigen was accomplished on an isoelectric-focusing column, using a sucrose density gradient support. Components were assayed for activity in skin testing and lymphocyte transformation. Comparison of column fractions to the whole antigen showed greater response to the whole antigen in in vivo and in vitro assays.

Coccidioides immitis vaccine: potential of an alkali-soluble, water-soluble cell wall antigen.

C-ASWS-M, the alkali-soluble, water-soluble cell wall antigen of Coccidioides immitis mycelia, was evaluated for its vaccine potential in mice. Vaccination with 0.5-, 1.5-, or 3-mg doses of C-ASWS-M in complete Freund adjuvant provided a significant level of protection against intraperitoneal challenge with 1,500 arthroconidia (P < 0.0001 with each dose). Vaccination with 1 mg of C-ASWS-M protected mice against intranasal challenge with 50 (P < 0.05) and 500 (P < 0.01) arthroconidia, but not against intranasal challenge with 1,500 arthroconidia (P > 0.05).

Reactivity of alkali-soluble, water-soluble cell wall antigen of Coccidioides immitis with anti-Coccidioides immunoglobulin M precipitin antibody.

The alkali-soluble, water-soluble cell wall antigen of Coccidioides immitis (C-ASWS) mycelia and spherules was shown to react with anti-Coccidioides immunoglobulin M (IgM) precipitin antibody, both in the classical tube precipitin test and in the immunodiffusion assay for tube precipitin antibody (IDTP). The reactions obtained between C-ASWS and reference IgM precipitin antibody were identical to the reaction obtained when reference coccidioidin (CDN) was used. Definitive proof that C-ASWS extracts contain antigenic determinants that are reactive with IgM tube precipitin antibody was obtained by solid-phase immunoadsorption. Elution of reference IDTP antiserum over a column containing mycelium C-ASWS coupled to Sepharose 4B completely adsorbed precipitin antibody; i.e., reactivity in the IDTP was demonstrable in the column eluate but not in the column effluent fraction. The antigenic composition of C-ASWS extracts was evaluated and compared with that of CDN by two-dimensional immunoelectrophoresis against burro anti-CDN. The results established that both mycelium and spherule C-ASWS contain antigenic determinants in common with only one antigen present in CDN. The latter, designated antigen 2, is a large polymer which is predominant among the antigenic components in CDN. On a dry weight comparison, antigen 2 determinants were most concentrated in spherule C-ASWS, followed by mycelium C-ASWS and reference IDTP antigen. The finding that C-ASWS extracts are reactive with IgM tube precipitin antibody and are antigenically identical to antigen 2 in CDN suggests that antigen 2 is the biologically active component of CDN in tube precipitin assays.

Antigenic heterogeneity of an alkali-soluble, water-soluble cell wall extract of Coccidioides immitis.

The antigenic composition of an alkali-soluble, water-soluble cell wall extract of Coccidioides immitis, designated C-ASWS, was assessed by two-dimensional immunoelectrophoresis against goat antisera to C-ASWS and coccidioidin. The results established that C-ASWS from mycelia or spherule cell walls is heterogeneous in composition, containing two distinct antigenic components. One is present as a polymer that is antigenically identical to a polymeric antigen in coccidioidin, designated antigen 2. The other component detected in C-ASWS presented an unusual precipitin pattern in that a cathodal leg was demonstrable in the absence of an anodal leg. This incomplete precipitinogen was also detected in coccidioidin. In addition to the finding that C-ASWS is antigenically heterogeneous, the results provide evidence that the conformational and/or configurational structure of the C-ASWS antigen 2 (or antigen 2-like polymer) is altered during physicochemical extraction. This conclusion is based upon the finding that the immunoelectrophoretic profile of the C-ASWS polymer differs from that of coccidioidin antigen 2. The C-ASWS polymer is characterized by having a small cathodal precipitin peak connected to a large anodal peak, whereas coccidioidin antigen 2 is characterized by a predominant cathodal peak.

Plasma levels of soluble interleukin 2 receptor, soluble CD30, interleukin 10 and B cell activator of the tumour necrosis factor family during follow-up in vasculitis associated with proteinase 3-antineutrophil cytoplasmic antibodies: associations with disease activity and relapse.

OBJECTIVES: To evaluate whether T cell activation, as reflected by levels of soluble interleukin 2 receptor (sIL2R), soluble CD30 (sCD30), IL-10 and B cell activator of the tumour necrosis factor family (BAFF) at diagnosis and during initial follow-up, is predictive for persistent or renewed antineutrophil cytoplasmic antibody (ANCA) positivity and clinical relapse in patients with vasculitis associated with proteinase 3-antineutrophil cytoplasmic antibodies (PR3-ANCA). METHODS: 87 Patients with PR3-ANCA-associated vasculitis and at least 2 years of follow-up were included in the study. At diagnosis, and at 3, 6, 12, 18 and 24 months after diagnosis, cytoplasmic ANCA titres were detected by indirect immunofluorescence (IIF), and PR3-ANCA, sIL2R, sCD30, IL-10 and BAFF levels were assessed by ELISA. 31 healthy volunteers provided plasma samples for comparison. Levels of immune markers were related to ANCA positivity and relapse during follow-up. RESULTS: Plasma levels of sIL2R, sCD30 and BAFF were higher in patients than in controls at all time points. Plasma levels of sIL2R, sCD30 and IL-10 were higher at diagnosis and relapse than during remission. At 18 months, sCD30 (p<0.001) and sIL2R levels (p = 0.01) were significantly higher in PR3-ANCA-positive patients (detected by ELISA) than in PR3-ANCA-negative patients. ANCA-positive patients detected by ELISA or IIF at 24 months had significantly higher plasma sCD30 levels (p = 0.02 and p = 0.03, respectively) than ANCA-negative patients. CONCLUSION: Increased T cell activation in patients with ANCA-associated vasculitis in remission during and after immunosuppressive treatment is associated with persistent or renewed ANCA positivity.

Soluble Fas ligand and soluble Fas in ocular fluid of patients with uveitis.

AIMS: To investigate the presence of soluble Fas ligand (sFasL) and soluble Fas (sFas) in ocular fluid of patients with uveitis. METHODS: Samples of aqueous humour (AH, n=17), vitreous fluid (n=9), and serum (n=60) were collected from patients with uveitis which included Behçet's disease, Vogt-Koyanagi-Harada disease, sarcoidosis, human T lymphotropic virus type 1 (HTLV-I) uveitis, sympathetic ophthalmia, HLA-B27 associated acute anterior uveitis, and ocular toxoplasmosis. The AH of patients with age related cataract without uveitis obtained during cataract surgery was used as controls (n=20). The amounts of sFasL and sFas were measured by enzyme linked immunosorbent assay. RESULTS: Significant amounts of sFasL were detected in AH of patients with age related cataract (non-uveitis group). sFasL was also detected in AH of patients with uveitis, though the amounts were slightly lower than those in the non-uveitis group. On the other hand, the levels of sFas in AH of patients with uveitis were significantly higher than those in controls. As for the disease activity, the levels of sFasL and sFas in the vitreous fluid of patients with active uveitis were significantly higher than those in inactive uveitis. sFasL in the serum of healthy donors and patients with uveitis was below detectable levels, except for patients with HTLV-I uveitis who had significant amounts of sFasL in the serum. The levels of sFas in the serum of patients with Behçet's disease, sarcoidosis, and HTLV-I uveitis were significantly higher than those of healthy donors. CONCLUSIONS: sFasL is present in the AH of non-uveitic eyes with age related cataract. Intraocular levels of sFasL and sFas are significantly increased in uveitis, particularly in active uveitis. These data suggest that intraocular sFasL and sFas may have a regulatory role in uveitis.

Plasma soluble fas and soluble fas ligand in chronic glomerulonephritis.

It has been reported that glomerular cells with apoptosis and positive Fas immunoreactivity are seen in proliferative glomerulonephritis (PGN). Fas induces apoptosis when it binds to Fas ligand (Fas-L) or soluble Fas-L (sFas-L). However, soluble Fas (sFas) blocks apoptosis by inhibiting binding between Fas and Fas-L or sFas-L. That is, Fas, Fas-L, and sFas-L are inducers of apoptosis, but sFas is an inhibitor of apoptosis. We studied the relationship between the plasma levels of sFas and sFas-L in 32 patients with various types of adult chronic glomerulonephritis. Patients with serum creatinine levels >1.5 mg/dl (132.6 micromol/l) were excluded. The plasma levels of sFas-L were within the normal limits in all patients. The plasma levels of sFas in the patients with minimal-change (n = 8) and membranous nephropathy (n = 7) were similar to the age- and sex-matched controls. However, the plasma sFas levels were significantly elevated in patients with mesangial PGN (n = 10) and membranoproliferative glomerulonephritis (n = 7)(3. 4 +/- 0.9 and 3.9 +/- 1.5 ng/ml, respectively) as compared with the age- and sex-matched controls (controls: 2.1 +/- 0.4 and 2.2 +/- 0.6 ng/ml, respectively). In PGN, according to increase of histological grade and decrease of creatinine clearance, the number of TUNEL-positive cells in glomeruli is decreased in spite of an increase of the Fas positivity, and plasma sFas is increased. The degree of proliferative change is determined by the balance between proliferation and apoptosis and/or necrosis. Therefore, increased plasma sFas in PGN may inhibit apoptosis in glomeruli and may be one of the progressing factors in PGN. Thus, we conclude that an increase in plasma sFas levels is important to the protection of apoptosis in PGN.

High-dose glucocorticoids increase serum levels of soluble IL-6 receptor alpha and its ratio to soluble gp130: an additional mechanism for early increased bone resorption.

OBJECTIVE: Glucocorticoids (GCs) at pharmacological doses stimulate bone resorption. Mechanisms of this action are unclear. The osteoclastogenic cytokine interleukin (IL)-6 acts through an oligomeric receptor consisting of two subunits, gp80 (or IL-6 receptor alpha, IL-6Ralpha) and gp130; both exist in membrane and soluble forms. Soluble IL-6Ralpha (sIL-6Ralpha) enhances, while sgp130 inhibits IL-6 signalling. In vitro, GCs enhance many effects of IL-6 by up-regulation of IL-6Ralpha. The aim of the present study was to assess acute changes of IL-6 system in the peripheral blood of patients given high-dose GCs. SUBJECTS AND METHODS: Serum levels of IL-6, sIL-6Ralpha, sgp130 and bone turnover markers were assessed before and each day during treatment in 24 multiple sclerosis (MS) patients undergoing high-dose (prednisolone, 15 mg/kg per day), short-term (3 to 5 days) intravenous GC therapy for relapse at the Regional Multiple Sclerosis Centre. RESULTS: An immediate and marked fall of osteocalcin and an early increase of C-terminal telopeptide of type I collagen were already noticed at day 2 (P < 0.001 and P < 0.02, respectively); both became more apparent in the subsequent days. IL-6 was always below or near the detection limit of our ELISA. sgp130 showed a slight increase. sIL-6Ralpha significantly increased, peaking at day 4 (P < 0.01). However, inter-individual variability of response was noticed. Four patients showed a slight decrease, while no change was observed in one patient and an increase was noticed in the remaining nineteen (maximum change ranging from +10% to +67% with respect to baseline). In these patients, a significant increase of sIL-6Ralpha/sgp130 ratio was apparent. No correlation was found between bone turnover markers and any measured component of the IL-6 system. CONCLUSIONS: sIL-6Ralpha and sIL-6Ralpha/sgp130 ratio are precociously increased in the peripheral blood of the vast majority of patients given high-dose, intravenous GCs. The increase of systemically available sIL-6Ralpha conceivably results in the enhancement of IL-6-dependent osteoclastogenesis. The role of such a mechanism in the bone loss observed in inflammatory and immune-mediated diseases (where abundancy of IL-6 in the bone microenvironment is expected) requires further investigation.

Clinical significance of serial measurement of the serum levels of soluble interleukin-2 receptor and soluble CD8 in malignant lymphoma.

We serially measured the serum levels of soluble interleukin-2 receptor (sIL-2R) and soluble CD8 (sCD8) in 36 patients with malignant lymphoma (33 non-Hodgkin's lymphoma cases and three Hodgkin's disease cases). The level of serum sIL-2R was significantly elevated in patients with active disease (18) compared to those in remission (18), and correlated with the clinical stage of the lymphoma. The temporal profile of the sIL-2R level reliably represented the disease status, which was judged clinically, during the course of the disease. In three patients, the tumor bulk paralleled the sIL-2R level. On the other hand, a less significant correlation was found between the serum sCD8 level and disease activity. The serial measurement of sCD8 appeared to be less useful for monitoring the disease activity, although there was a significant correlation between the sCD8 and sIL-2R levels. This study indicates that serial measurement of the serum sIL-2R level may be useful for monitoring the tumor burden in response to treatment and for early detection of disease progression in malignant lymphoma.

Blocking interleukin-6 activity with chimeric anti-IL6 monoclonal antibodies in multiple myeloma: effects on soluble IL6 receptor and soluble gp130.

Interleukin-6 (IL6) plays a major role in the pathogenesis of multiple myeloma. In patients with monoclonal gammopathy serum levels of sIL6R have been found to be increased. The role of IL6 in the regulation of soluble receptors is still unclear. In a phase I/II study we treated 12 myeloma patients with high-affinity chimeric anti-IL6 monoclonal antibodies. This treatment resulted in a total in vivo blockage of IL6 activity and as a result we had an unique opportunity to gain insight into the possible regulation effects of IL6 on these soluble IL6 receptors. Pre-treatment sIL6R levels were elevated in 9 of the 12 patients; pre-treatment sgp130 levels were significantly increased in all patients. Total blockage of IL6 activity by the high-affinity cMab did not influence sIL6R in 10 of these 12 patients and sgp130 levels remained stable in all patients. Of the 2 patients whose sIL6R levels increased during therapy, one had progressive disease and the other developed an acute infection. We conclude that in most end-stage myeloma patients sIL6R and sgp130 serum levels are elevated, but that there is no relation between IL6 activity and sIL6R or sgp130 levels.

Fat-soluble and water-soluble vitamin contents of breast milk from Japanese women.

To determine the concentrations of fat-soluble and water-soluble vitamins in the maternal milk of Japanese women, we collected human milk samples from more than 4,000 mothers living throughout Japan between December 1998 and September 1999, and defined as group A the 691 samples among these that met the following conditions: breast milk of mothers who were under 40 y of age, who did not smoke habitually and/or use vitamin supplements, and whose babies showed no symptoms of atopy and had birth weights of 2.5 kg or more. We then analyzed the contents of vitamins individually. Large differences were observed among the contents of individual human milk samples. The mean contents of each component were as follows: vitamin A, 159.0 +/- 95.2 IU/100 mL; vitamin E, 0.325 +/- 0.165 alpha-TE mg/100mL; vitamin D3 (cholecalciferol), 8.0 +/- 10.7 ng/100mL; vitamin B1 (thiamin), 12.3 +/- 3.2 microg/100 mL; vitamin B2, 38.4 +/- 12.7 microg/100 mL; vitamin B6, 5.7 +/- 2.5 microg/100 mL; vitamin B12, 0.04 +/- 0.02 microg/100 mL; vitamin C, 5.1 +/- 1.9 mg/100 mL; biotin, 0.50 +/- 0.23 microg/100 mL; choline, 9.2 +/- 1.8 mg/100 mL; folic acid, 6.2 +/- 2.9 microg/100 mL; inositol, 12.6 +/- 3.6 mg/100 mL; niacin (nicotinamide), 32.9 +/- 20.4 microg/100 mL and pantothenic acid, 0.27 +/- 0.09 mg/100 mL. The concentrations of derivatives and/or related compounds of vitamin A (retinol, beta-carotene), vitamin E (alpha-, beta-, gamma-, and delta-tocopherol), and B2 (riboflavin, FMN, and FAD) were determined separately. The contents of each were found to vary greatly as the duration of lactation increased. The present results indicate that it is necessary to evaluate individual differences in human milk in order to perform valid research regarding infant formula.

[Soluble P-selectin - a marker of platelet activation and vessel wall injury: increase of soluble P-selectin in plasma of patients with myocardial infarction, massive atherosclerosis and primary pulmonary hypertension].

AIM: A comparative analysis of the content of the soluble form of cell adhesion protein P-selectin in the blood plasma of patients with acute myocardial infarction (AMI), massive atherosclerosis (MA) and primary pulmonary hypertension (PPH), investigation of the relationship between plasma content of P-selectin and known markers of platelets and endothelial cells activation, preliminary assessment of the prognostic value of P-selectin determination. MATERIALS AND METHODS: This study included 16 patients with AMI, 20 patients with MA, 21 patients with PPH and 18 healthy donors. The follow-up was 1-5 years. End-points in the group of patients with AMI were recurrent acute coronary syndrome and coronary artery by-pass operation, in the group with MA--thrombotic complications (acute coronary syndrome, ischemic stroke) and in the group with PPH--death. P-selectin was measured by ELISA and platelet factor 4 (PF4), thromboxane B2 (TXB2), endothelin-I and stable prostacyclin metabolite 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha) by means of commercial ELISA kits. RESULTS: Mean level of P-selectin in blood plasma of patients with AMI (1 day) (361 +/- 18 ng/ml), MA (410 +/- 31 ng/ml) and PPH (627 +/- 83 ng/ml) was increased in comparison with the group of healthy donors (269 +/- 12 ng/ml) (everywhere p < 0.001). In AMI, P-selectin was increased on day 1 only, on days 2, 3 and 10-14 of the disease the level of P-selectin was significantly lower than on day 1 and did not differ from the control level in the group of donors. In patients with MA a significant correlation was detected between plasma content of P-selectin and platelet activation marker PF4 (r = 0.606, P = 0.007) and in patients with PPH between the content of P-selectin and another platelet activation marker TXB2 (r = 0.622, p = 0.013). However, no correlation was found in PPH patients between the content of P-selectin and markers of endothelial activation and/or damage (endothelin-1 and 6-keto-PGF1 alpha). Difference in the concentration of P-selectin in patients with or without end-points during the follow-up period was detected in patients with AMI (353 +/- 14 ng/ml and 451 +/- 24 ng/ml, p = 0.009) and PPH (477 +/- 58 ng/ml and 927 +/- 184 ng/ml, p = 0.017) but not with MA (426 +/- 37 ng/ml and 361 +/- 24 ng/ml, p = 0.295). CONCLUSION: The level of P-selectin in plasma was increased in patients with acute thrombosis (AMI, 1 day) as well as in patients without clinical signs of thrombosis but with a massive injury of the vasculature (MA and PPH). The increase of P-selectin was, presumably, caused by its secretion from activated platelets since its concentration in plasma correlated with platelet concentration but not endothelial activation markers. Preliminary data indicate that blood plasma soluble P-selectin may be considered as a potential prognostic marker in AMI and PPH.

[Determination of serum soluble interleukin-6 receptor and soluble gp130 levels in patient with pregnancy induced hypertension and its significance].

OBJECTIVE: To observe the changes of serum soluble interleukin-6 receptor (sIL-6R) and soluble gp130 (sgp130) in patients with pregnancy induced hypertension. METHODS: Enzyme linked immunosorbent assay (ELISA) was used to determine serum sIL-6R and sgp130 levels in 40 patients with pregnancy induced hypertension (study group), 20 normal non-pregnant women (control group I) and 20 normal pregnant women (control group II). RESULTS: In study group, sIL-6R was (196.7 +/- 12.9) micrograms/L and sgp130 was (379.4 +/- 79.3) micrograms/L. In control group I, sIL-6R was (174.8 +/- 46.2) micrograms/L and sgp130 was (273.6 +/- 28.3) micrograms/L. In control group II, sIL-6R was (174.4 +/- 48.3) micrograms/L and sgp130 was (254.4 +/- 34.7) micrograms/L. SIL-6R and sgp 130 were higher in study group than those in control groups with significant difference (P < 0.01). In study group, the more severe the patients, the higher the sIL-6R and sgp130 levels. There was significant difference (P < 0.01). There was no difference in sIL-6R and sgp130 levels between control groups (P > 0.05). CONCLUSIONS: Serum sIL-6R and sgp130 levels are related to the development of pregnancy induced hypertension.

Soluble Fas and soluble Fas L levels in patients with acute pancreatitis.

The FasL-Fas system is an apoptosis induction system and plays an important role in homeostasis and biophylaxis. The present study was conducted to investigate soluble Fas (sFas), soluble Fas ligand (sFasL), and tumor necrosis factor alpha (TNF-alpha) in patients with acute pancreatitis. As acute pancreatitis became severe, the levels of sFas in the serum increased significantly, while those of sFasL decreased significantly. A significant inverse correlation was observed between the serum levels of sFas and those of sFasL. Also, a significant positive correlation was observed between the levels of TNF-alpha and sFas. A greater increase in serum sFas and decrease in serum sFasL levels was observed in patients with complicating multiple organ dysfunction syndrome (MODS) than in those without it. The results of the study suggest that the pathological aggravation of acute pancreatitis could be related to changes in the Fas-FasL system.

The therapeutic effects of oil-soluble hysterosalpingography contrast medium following water-soluble hysterosalpingography contrast medium.

Previous studies have revealed that patients who underwent hysterosalpingography (HSG) with an iol-soluble contrast medium (OSCM) rather than a water-soluble contrast medium (WSCM) had higher subsequent fertility rates. In this randomized prospective study, the fertility rates among 109 patients following HSG were found to be 31% (19/61) in the WSOM group and 38% (18/48) in the WSOM + OSCM group. No significant difference was noted between these two groups, whether their infertility was associated with endocrine factor, male factor, endometriosis, mechanical factor or some other unexplained factor.
