PROBLEM : To demonstrate whether monocyte chemotactic and activating factor (MCAF) and interleukin-6 (IL-6) are present in the seminal plasma, and whether these presence is modulated by leukospermia. METHODS : Semen samples from 53 men were obtained by masturbation and examined for the presence of MCAF and IL-6 by enzyme immunoassay (EIA). Semen samples were obtained from 28 infertile men without leukospermia, 16 infertile men with leukospermia, and nine proven-fertile men. The correlation between the amount of MCAF in the seminal plasma with some spermiogram parameters and other cytokines such as IL-6 and IL-8 was statistically evaluated. RESULTS : Immunoreactive MCAF was detected in the seminal plasmas of all 53 subjects. The MCAF titer in the seminal plasma of patients with leukospermia (11.19 ± 2.75 μg/1) was significantly higher than that in the seminal plasma of the patients without leukospermia (3.24 ± 0.53 μg/1) and the fertile men (2.78 ± 0.35 μg/1) (P < 0.001). The IL-6 titer in the seminal plasma of the patients with leukospermia (21.05 ± 4.49 ng/1) was also significantly higher than that in the seminal plasma of the patients without leukospermia (8.77 ± 1.92 ng/1) and the fertile men (6.94 ± 1.27 ng/1) (P < 0.01). There was a high degree of correlation among the levels of MCAF, IL-6 and IL-8 in the seminal plasma. CONCLUSIONS : These findings demonstrated the presence of MCAF and IL-6 in the seminal plasma, and that the levels of these cytokines were elevated in the seminal plasma of the infertile patients with leukospermia.  相似文献

The salivary glands of non-obese diabetic (NOD) mice and BALB/c controls were evaluated for the stimulatory effects of the following neuropeptides; substance P (SP), vasoactive intestinal polypeptide (VIP), and neuropeptide Y (NPY). Injection of either of the three neuropeptides in combination with the muscarinic–cholinergic agonist pilocarpine increased saliva flow rates in BALB/c mice while there was no observable augmentation to flow rates in pre-diabetic or diabetic NOD mice. Small increases in protein content of the stimulated saliva were observed in the BALB/c group of animals with the injection of any of the above neuropeptides in combination with pilocarpine. In pre-diabetic NOD animals, only VIP and NPY increased the protein content-ratio above pilocarpine alone. Radioimmunoassay determination of neuropeptide concentrations in the submandibular and parotid glands revealed reduced levels of SP with diabetes onset as compared with pre-diabetic NOD or BALB/c mice. The levels of NPY were similar between BALB/c and NOD animals except in the pre-diabetic parotid gland where NPY concentrations were 1.3-fold greater. On the other hand, VIP concentrations were substantially reduced in the submandibular gland of NOD mice, while in the parotid gland neuropeptide levels were evaluated 3.8-fold relative to BALB/c controls. Immunohistochemical staining of the parotid and submandibular glands for SP revealed primarily ductal cell staining which was reduced with diabetes onset in NOD animals. These findings further define the sialoadenitis observed in NOD mice to be due, in part, to a general loss of neurotransmitter responsiveness on the part of salivary gland cells.  相似文献

Abstract: The Endoscopic resection of gastric tumors following local injections of hypertonic saline-epinephrine solution (ERHSE) was performed on 72 lesions (69 patients) of gastric tumors at Yoyogi Hospital etc. from March, 1983, to December, 1989. These included 40 cases of adenoma, 31 cases of carcinoma, and one carcinoid tumor. The average length of the major axis of the endoscopically resected tumors was 12 ± 9 mm. The curative rate at the first attempt was 94% (64 of 68 lesions). The curative rate of the final procedure was 99% (67 of 68 lesions). This excluded 4 lesions in 3 patients in whom a follow-up examination was not possible. There was no relationship found between the final cure rate and the form and location of the lesions. Fifty four lesions were resected with one session of snare cautery; the average length of their major axis was 9 ± 6mm. The resection of 18 lesions was done piecemeal, and the average length of their major axis was 20 ± 10mm. A statistical significance was noted between the size of the lesions which could be resected with one session of snare cautery and those treated by the piecemeal method, but no difference was noted in the location of lesions for the two groups. The indication for ERHSE was assessed in accordance with the cases that resulted in piecemeal resection, those in which the first ERHSE left residual tumor tissues, and those with perforation. ERHSE could be performed with difficulty on lesions which were (1) on the sharply bending gasric wall, (2) observed only tangentially, (3) inadequately observed. These lesions were situated on the gastric fornix, cardia, and their vicinities, the gastric angulus, posterior wall and greater curvature of the gastric body, and anterior wall and lesser curvature of the middle to the upper gastric body.  相似文献

Abstract: Biliary obstruction has been recognized to inhibit excretion of antibiotics into bile. In the present study, using cefpirome sulfate (CPR), we sought to determine the effect of biliary pressure on antibiotic transfer into bile in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Thirty-six patients with a variety of biliopancreatic diseases (free of renal disease or hypoproteinemia) received a single intravenous dose of CPR (1 g) prior to ERCP. Under fluoroscopy a diagnostic catheter with a metal ball tip was advanced into the middle portion of the extrahepatic bile duct or, in cases of common bile duct obstruction, above the obstruction. Biliary pressure was measured via the same catheter using duodenal pressure as a reference. Subsequently, bile was aspirated, and blood was withdrawn simultaneously. The mean interval between CPR administration and the bile and blood samplings was 67±12 minutes. The bile CPR concentration and the bile/serum ratio of CPR concentrations showed a significant inverse correlation with biliary pressure, but the serum CPR concentration did not. The bile CPR concentration and the bile/serum ratio of CPR concentrations differed significantly between the group with normal biliary pressures, below 10 mmHg, and that with biliary pressures exceeding 10 mmHg. The serum CPR concentrations of the two groups were similar. These results suggest that biliary pressure plays an important role in determining antibiotic transfer into bile.  相似文献

We describe a very rare case of synchronous granular cell tumor of the bladder, endometrial carcinoma and endometrial stromal sarcoma. A 55‐year‐old woman with a 4‐month history of genital bleeding was cytologically diagnosed with endometrial carcinoma. Imaging studies suggested concomitant bladder tumor with the possibility of direct invasion from endometrial carcinoma. Total abdominal hysterectomy with bilateral salpingo‐oophorectomy and transurethral resection of bladder tumor was performed. The bladder tumor comprised polygonal cells with abundant eosinophilic, finely granular cytoplasm, separated by collagenous tissue. Neither nuclear pleomorphism nor tumor necrosis was found. Immunohistochemical expression of neural markers of neuron‐specific enolase and S‐100 allowed the diagnosis of granular cell tumor (GCT) of the bladder. Microscopic examination of endometrium revealed endometrioid adenocarcinoma with squamous differentiation (EAC). Ill‐defined nodular lesion comprising endometrial stromal sarcoma (ESS) was accidentally found in myometrium. Postoperatively, the patient underwent radiotherapy. This is the first well‐documented case of synchronous triple tumors comprising GCT of the bladder, uterine EAC and ESS.  相似文献

BACKGROUND: Data on female partners' satisfaction are scarce, although there have been many articles on patient satisfaction after sildenafil citrate treatment. The aim of this study was to evaluate the satisfaction of female partners of patients receiving sildenafil citrate for their erectile dysfunction (ED) and to assess the female partners' sexual function. METHODS: Ninety-eight patients with ED were treated. Their female partners were asked to answer a questionnaire we have prepared to evaluate the efficacy of treatment, sexual satisfaction and changes in quality of life. It also included a question about female sexual function. From the results, the relationship between their female partner's satisfaction and efficacy of treatment, as well as female sexual function, were assessed. RESULTS: Thirty (31%) questionnaires were returned to us for analysis. Effectiveness of the treatment was acknowledged by 90% of the partners. An improvement in their partner's quality of life was noticed by 60% of the women. The majority (66.7%) of the female partners were satisfied with sildenafil citrate treatment and 20% were disappointed. Moreover, 20% of the female partners were concerned about adverse events. Regarding female sexual function, some form of sexual dysfunction affected 46.7% of the women. Furthermore, a significant number (P = 0.0230) of the female partners disappointed with the treatment had some kind of sexual dysfunction. CONCLUSIONS: The results indicated that female partners reported relatively high levels of treatment satisfaction. Female partners' sexual function and anxiety regarding adverse events should be evaluated when their satisfaction with sildenafil citrate treatment is poor despite an improvement of erectile function.  相似文献

BACKGROUND: The kidney eliminates the major fraction of plasma oxalate. It is well known that oxalate is freely filtered by glomeruli and secreted by the proximal tubules. However, the renal handling of oxalate in distal nephrons, which is considered as playing an important role in stone formation, remains obscure. METHODS: At 15-180 min after intravenous injection of 14C-oxalate to rats, the intrarenal localization of radioactivity was quantitatively measured by the radioluminographic method using a bioimaging analyzer. Tissue radioactivity was compared with plasma, and urinary radioactivities were measured by a liquid scintillation counter. The control study was conducted with 14C-inulin. RESULTS: The radioactivity of 14C-oxalate in the papilla was 10 times greater than in the cortex and eight times greater than in the medulla 180 min after injection when almost no radioactivity was present in the urine. In contrast, the radioactivity of 14C-inulin was nine times less in the papilla than in the cortex at the same time. CONCLUSION: Oxalate remains in the renal papilla for an extended period. This accumulation of oxalate may be attributed to calcium oxalate crystal fixation along the deep nephron which is considered to be the first step of stone formation.  相似文献

Abstract— The anti-anginal effect of nitroglycerin and prostacyclin was examined using, as an index, the ischaemic electrocardiogram (ECG) change (ST elevation) induced by intracoronary arterial injection of 9,11-dideoxy-11α,9α-epoxymethano-PGF (U-46619), a stable thromboxane A2 agonist, in anaesthetized rats. The ST elevation induced by U-46619 (5–20 μg kg?1, i.c.a.) was dose-dependent and reproducible. U-46619-induced ST elevation was markedly prevented by the pretreatment of intravenous administration of prostacyclin (0·01 μg kg?1), and to a lesser extent by nitroglycerin (0·3 mg kg?1). Simultaneously, platelet count decreased significantly in the coronary arterial blood which indicated that platelet aggregation was enhanced by U-46619. The decrease of platelet count in coronary arterial blood at the time of ST elevation was significantly suppressed by prostacyclin (0·1 μg kg?1, i.v.), but not by nitroglycerin (0·3 mg kg?1, i.v.). These results suggest that the ST elevation induced by intracoronary arterial injection of U-46619 may be derived from spasm of coronary artery and platelet aggregation in the intracoronary artery in rats.  相似文献
