Abstract
The usefulness of percutaneous transluminal coronary angioplasty (PTCA) was assessed in patients with exercise-induced asymptomatic myocardial ischemia (silent ischemia) and compared with exercise-induced symptomatic myocardial ischemia (symptomatic ischemia). Patients with single vessel coronary artery disease (51 with angina pectoris, 40 with old myocardial infarction) and evidence of stress-induced ischemia on thallium-201 single photon emission computed tomography (SPECT) underwent successful PTCA. Thirty-seven percent of angina patients and 60% of infarction patients showed asymptomatic exercise-induced ischemia. There was no significant difference in population characteristics between silent and symptomatic patients. Patients with silent angina had significantly higher percentage thallium uptake and washout rate than symptomatic patients. After PTCA, both percentage diameter stenosis and percentage thallium uptake were improved in all patients with angina irrespective of the presence or absence of symptoms. There were no significant differences in percentage thallium uptake and washout rate between patients with silent and symptomatic infarction. After PTCA, percentage diameter stenosis, percentage thallium uptake, and washout rate improved in all infarction patients irrespective of the symptoms. Zero percent of silent angina patients, 12% of symptomatic angina patients, 12% of silent infarction patients, 19% of symptomatic infarction patients had cardiac events during about 4.5 years after PTCA. The incidence of cardiac events did not significantly differ in any patient group. PTCA improved myocardial perfusion in all patients, and the incidence of cardiac events did not differ between the silent and symptomatic groups. Revascularization with PTCA is suitable for patients with silent as well as symptomatic ischemia.

Abstract
We have observed that naturally occurring serum antibodies generated a 30 Kd band in a platelet immunoblot assay. The target protein had the same molecular weight (30 Kd) under nonreduced and reduced electrophoretic conditions, and could be immunoblotted from either autologous or homologous platelet lysates. Also, the 30 Kd reactive autoantibodies could be totally adsorbed by platelet cytoskeletons. From these data one likely candidate for the autoantibody target was the intracellular platelet protein tropomyosin. Indeed, a commercially available monoclonal anti-tropomyosin antibody reacted with proteins comigrating with this 30 Kd band; affinity purified human platelet tropomyosin was bound by the antibodies that recognized the 30 Kd protein. This body of evidence conclusively demonstrated that naturally occurring serum autoantibodies reacted with the platelet cyto-skeleton protein-tropomyosin. These tropomyosin specific antibodies were found in roughly the same percentage of sera from patients with chronic idiopathic thrombocytopenic purpura (ITP) as from normal individuals.

Abstract
Blood group ABH antigens are associated with platelets as intrinsic determinants and extrinsically adsorbed antigens, and exist both on glycosphingolipids and on glycoproteins (GPs). We now provide direct evidence that the blood group ABH antigens are prominently associated with platelet GPIb and GPIIb. By immunoprecipitation, a murine monoclonal anti-A antibody precipitated surface-biotin-labelled blood group A1 platelet membrane proteins with electrophoretic characteristics identical to those of GPIb/IX and GPIIb/IIIa. By immunoblotting of SDS-PAGE separated blood group A1 platelet proteins the monoclonal anti-A antibody bound to proteins with electrophoretic characteristics identical to those of GPIb and GPIIb. When immunoaffinity purified GPIb/IX and GPIIb/IIIa, derived from blood group O, A1 and A2 platelets, were employed for immunoblotting, GPIb and GPIIb only from A1 platelets bound the monoclonal anti-A antibody. By ELISA, wherein monoclonal antibodies specific for GPIb (APl) and the GPIIb/IIIa complex (AP2) were used to capture and hold antigens from platelet lysate, human anti-A antibodies reacted with these proteins derived from blood group A1 platelets; proteins from blood group A2, O and B platelets showed no reactivity. These results indicate that blood group A antigen is associated with GPIb and GPIIb derived from blood group A1 but not A2 platelets.

Abstract
Chronic idiopathic thrombocytopenic purpura (ITP) is a consequence of rapid platelet destruction caused by circulating platelet antibodies. In this study we compared three methods for detecting serum platelet antibodies in a population of 65 patients with chronic ITP. In two of the techniques intact platelets were used as the antibody target, i.e. the whole platelet ELISA and the flow cytometric assay; in the third an antigen-specific modified antigen capture ELISA (MACE) was employed. By using the whole platelet ELISA and the flow cytometric assay 35% and 45% of the patients, respectively, displayed an antiplatelet antibody. In most cases (26 or 29 patients) IgG was the predominant antiplatelet immunoglobulin. As analysed using the MACE-technique glycoprotein (GP) Ib/IX-specific antibodies occurred with the same frequency as antibodies specific for GPIIb/IIIa. Moreover, there was a poor correlation between the MACE results on the one hand and results from the intact platelet-based techniques on the other, i.e. several patients were positive in one assay whereas they were negative in the other. We conclude that all three techniques have their merits and demerits; it appears reasonable that they should be used together in the evaluation of the autoimmune process of chronic ITP.

Abstract
In chronic idiopathic thrombocytopenic purpura (ITP) platelet destruction is caused by antibodies directed against platelet membrane glycoproteins (GP), and the predominant autoantigens are known to be GPIb/IX and GPIIb/IIIa. In a recent study we reported that these antibodies frequently had a restricted light chain phenotype, thereby supporting a clonal origin. Similar findings and the presence of clonal B-cell populations in immune thrombocytopenias have been reported by others. In the present study we further explored the hypothesis of clonal B-cell expansions in chronic ITP. Twenty patients with chronic ITP were investigated. Antibodies were detected with an ELISA (MAIPA) specific for GPIb/IX and GPIIb/IIIa; circulating clonal B lymphocytes were assessed by flow-cytometric (FACS) clonal-excess analysis and by analyzing Ig-gene rearrangements (CDR3) with the PCR technique. Nine patients displayed a GP-specific antibody restricted to either kappa or lambda phenotype. However, FACS analysis and Ig-gene rearrangement studies did not disclose any circulating clonal B-cell population. Considering the sensitivity of the FACs analysis and Ig-gene rearrangement for detection of clonal B-cell populations, the hypothesis of clonally derived autoantibodies in ITP is still valid. Most probably, the clonal B-cell expansion responsible for the production of autoantibodies in ITP, if present, is below the detection limit for the techniques employed.

Abstract
The antibody domain responsible for the interactions between platelet glycoproteins (GP) and serum IgG autoantibodies in patients with chronic idiopathic thrombocytopenic purpura (ITP) was studied. Sera from nine non-transfused ITP patients and 20 normal controls and a serum containing an anti-PlA1 antibody were employed. Serum, purified IgG and F(ab')2 fragments were prepared and their binding to platelet GPIb/IX and GPIIb/IIIa were analysed using a modified MAIPA assay and an antigen capture ELISA. In all experiments most of the autoantibodies studied behaved identically to the anti-PlA1 antibody in that the IgG-F(ab')2 fragments retained their ability to bind to the respective glycoprotein. Substituting the enzyme-conjugated secondary antibody (Fab specific), in the MAIPA assay, with an Fc specific antibody removed all reactivities observed against platelet GPs, produced by IgG-F(ab')2 fragments. Furthermore, in an antigen-capture ELISA, IgG autoantibodies against platelet GPIb/IX and/or GPIIb/IIIa were blocked preferentially by pre-incubating the ITP sera with a goat anti-human IgG (F(ab')2 specific) antibody, but not with an anti-Fc antibody. We conclude that these ITP patients produced antibodies specific for platelet GPIb/IX and/or GPIIb/IIIa, and that the autoantibody-platelet interaction was mediated by the classic Fab binding.

Abstract
The objective of the present study was to further disclose the autoantigenic repertoire carried by the platelet glycoprotein (GP) IIb/IIIa complex. IgG-F(ab')2 fragments were prepared from two prototype ITP patients, and their ability to block the binding of GPIIb/IIIa reactive antibodies derived from other patients with ITP was evaluated using a modified MAIPA asay; a PlA1 alloantiserum and 20 normal sera were included as controls. It was found that the two prototype IgG-F(ab')2 fragments were each able to significantly block the binding of serum IgG to GPIIb/IIa in six (55%) and seven (64%) out of 11 patients with chronic ITP, respectively. No significant blocking effect was observed for IgG-F(ab')2 fragments prepared from normal subjects. Also, the binding of the PlA1 alloantiserum to its epitope on GPIIIa was not affected by any of the blocking IgG-F(ab')2 fragments exploited in the study. These data substantiate that in chronic ITP at least half of the GPIIb/IIIa reactive sera bind to homogenous autoepitopes.

Abstract
Antibodies involved in the pathogenesis of chronic idiopathic thrombocytopenic purpura (ITP) react most frequently with platelet glycoprotein (GP) Ib/IX and GPIIb/IIIa. However, uncertainty as to the specificity, frequency, and clinical significance of such antibodies still remains. By using a modified antigen-capture ELISA (MACE), an immunoprecipitation assay, and an immunoblot assay, sera from 60 patients with chronic ITP were analyzed. GP-specific antibodies were found in 50% (30/60) of the patients, with 14 patients having antibodies directed solely to GPIIb/IIIa, 8 holding antibodies specific only for GPIb/IX, and 8 possessing antibodies against both antigens. Serum antibodies were more frequently (p < 0.01) detected in either active and/or non-splenectomized ITP patients. Moreover, in patients displaying antibodies against GPIb/IX, significantly (p < 0.05) lower platelet counts were observed. Using the immunoblot assay, antibodies specific for a 30 kD platelet antigen were detected in 12 of 60 patients. This antigen could not be immunoprecipitated from surface labelled platelet membranes, indicating an intracellular location. We conclude that in chronic ITP, (1) the frequency of anti-GPIIb/IIIa antibodies is close to that of anti-GPIb/IX antibodies, (2) anti-GP antibodies are more likely to be detected in patients with an active disease status and, (3) a 30 kD internal platelet protein is another frequent antigen.

Abstract
To address the assumption of clonally restricted antibodies in immune thrombocytopenias we studied sera from 19 patients with chronic ITP known to possess antibodies reactive with glycoprotein (GP) Ib/IX and/or GPIIb/IIIa. These sera were re-analysed using the standard monoclonal antibody immobilization of platelet antigens (MAIPA) assay and 16 patients exhibited IgG antibodies reactive with GPIIb/IIIa; seven patients showed also a reactivity with GPIb/IX. Employing a light-chain-specific MAIPA assay, 75% (12/16) of these sera displayed GPIIb/IIIa-specific antibodies that were light chain restricted; only 13% (2/16) of the GPIIb/IIIa reactive sera showed a mixed kappa and lambda phenotype. A light-chain-restricted phenotype was also seen for the GPIb/IX reactive antibodies. To further substantiate these findings, the MAIPA assay was modified in order to avoid interference from human anti-mouse antibodies. A high frequency of light-chain restricted platelet antibodies was also found using the modified MAIPA technique. These results support the hypothesis of a clonal B-cell expansion in immune thrombocytopenias, producing antibodies with a restricted idiotype repertoire and reacting with a limited number of epitopes.

Abstract
The secretion of progesterone and 20 alpha-dihydroprogesterone (20 alpha-DHP) during the estrous cycle and the effects of prostaglandin F2 alpha (PGF2 alpha) and 20 alpha-DHP on the secretion of these two steroids during the midluteal phase in goats were studied. The mean progesterone concentration in the peripheral plasma was extremely low (< 0.01 ng/mL) on the day of estrus. The concentration increased to a maximum (7.80 ng/mL) on about day 10 after estrus, and decreased rapidly during the last 3 days of the cycle. The plasma concentration of 20 alpha-DHP also was low (0.86 ng/mL) on the day of estrus, but increased gradually after estrus and decreased gradually in the last 5 days of the cycle (to 3.22 ng/mL). The ratio of progesterone to 20 alpha-DHP was > 1 after day 2 of estrus, but decreased and fell to < 1 during the last 3 days of the cycle. An injection of 3 mg of PGF2 alpha decreased the secretion of progesterone within 30 min, but affected the secretion of 20 alpha-DHP little until 2 h. The ratio of progesterone to 20 alpha-DHP fell to < 1 after 24 h. Three of the five goats given such an injection came into estrus within 2 days, and the other two came into estrus within 3 days. An injection of 15 mg of 20 alpha-DHP did not affect progesterone secretion or the estrous cycle length. These results indicate that in the goat after estrus, there is much 20 alpha-DHP in the peripheral plasma. Progesterone may be catabolized to the biologically inactive steroid, 20 alpha-DHP, during luteolysis.

Abstract
Forty two cases of anorectal melanoma were studied which constituted 1.19% of all the anorectal malignancies collected in this series. 90% of the tumors located near by the dentate line. Grossly, the masses were nodular, fungiform or ulcerated. Histologically, pleomorphic tumor cells mixed together giving a feature somewhat like either carcinomatoid or sarcomatoid, with a predominance of one kind of the malignant cells. Histopathologic observation supported the idea that this tumor developed from the melanocytes and nevus cells located at the basal layer of the epithelium. Immunohistochemistry proved that melanocytes originated from the neural crest. S-100 protein was marker with high sensitivity but the specificity not ideal, so that, varied markers are recommended in order to improve the accuracy of diagnosis.

Abstract
The effect of nicorandil on myocardial perfusion in ischemic heart disease was studied using exercise-load Tl-201 myocardial SPECT (Ex-SPECT). ExSPECT was carried out in 12 patients with previous myocardial infarction (OMI) and 9 with angina pectoris (AP) before and after administration of nicorandil 15 mg/day, for three or more weeks; %Tl uptake and the washout rate in infarcted or ischemic areas were calculated from short axial images using the Bull's eye method. In the OMI group, %Tl uptake and washout rates in the infarction areas improved significantly from 52.4% and 0.25 before nicorandil to 60.4% and 0.38 after nicorandil. In the AP group, too, %Tl uptake and washout rates showed a significant improvement from 56.9% and 0.10 before to 69.1% and 0.33 after administration of nicorandil. Six subjects who had not received the drug, and who showed negative washout rates, had high improvement rates when nicorandil was administered, suggesting that the drug could increase myocardial perfusion during exercise loading as well as suppressing coronary spasm. Ex-SPECT was carried out in 4 subjects before and after the administration of nicarandil and after subsequent surgical treatment (PTCA or CABG) and the effects of the two therapies were compared. The washout rate was improved from 0.01 to 0.34 by the administration of nicorandil, and a notable increase in coronary artery blood flow was achieved compared to the level after surgical treatment, i.e. 0.50. It is concluded that normal dosages of nicorandil have a powerful direct effect of dilating the coronary arteries without any influence on preload or afterload.

Examination of the RBC immunofunction in rabbit experimental traumatic uveitis with Guo's method of complement-labelled yeast revealed that the percentage of RBC C3b receptor rosette and the activity of red cell immune adherence (RCIA) enhancing factor in sera were markedly lower, while the percentage of RBC surface immune complex rosette, the activity of the RCIA-inhibiting factor and the CIC in sera were higher than those in the normal controls, indicating that the lowered RBC immunofunction was involved in pathogenesis of the experimental traumatic uveitis.

Abstract
Synchronous measurements of renal function and T-cell subsets were taken in 51 cases of chronic renal failure (CRF) patients. Cordyceps sinesis 3-5 g/d was given to 28 out of these 51 patients, which was considered as follow-up group. The results were stated as follows: (1) Obvious decrease of OKT3, OKT4, OKT4/OKT8 was found in CRF (P < 0.01). (2) OKT4 and OKT4/OKT8 were proportional to plasma albumin and Hb levels (P < 0.05). (3) After administration of Cordyceps sinesis, improvement of renal function and OKT4, OKT4/OKT8 were confirmed. This study indicated that cellular immune function was decreased in CRF. Administration of Cordyceps sinesis might improve their renal function and as the same time enhance the cellular immune function in CRF.
