A total of 108 samples of sputum obtained from twenty patients with bronchial asthma were examined for appearance of basophils and eosinophils. Both cell types are present in sputum during an asthmatic attack and disappear at the conclusion of the attack. Their presence correlates with the severity of the disease. It has previously been demonstrated that the blood basophils count falls during attacks of bronchial asthma, and the present study suggests that basophils move from the blood stream into bronchial tissue during the acute phase of an asthmatic attack. 相似文献

Background. In order to evaluate the prevalence rates of Raynaud's phenomenon (RP) and specific clinical signs related to progressive systemic sclerosis (PSS) in the general population of Japan, inquiries were made concerning RP in the hands and dermatologic examinations were also conducted. Methods. One thousand and sixty-three subjects (332 men and 731 women) over 30 years of age who underwent inhabitants' health examinations in 1990 were considered for this study. Results. The prevalence of RP was 3.0% in men and 3.4% in women. In 8 men and 17 women with RP who received the blood tests, the positive rates of antinuclear antibody (ANA) were 12.5% and 35.3% in men and women, respectively. The prevalence rates of all five specific clinical signs related to PSS, sclerodactyly, pitting scars of the fingers, brown pigmentation of the body, shortened frenulum of the tongue, and flexion contracture of fingers, were under 2% in men and 3% in women. In women with RP the prevalence rates of sclerodactyly, pitting scars of the fingertips, brown pigmentation of the body, and shortened frenulum of the tongue were 16.0, 4.0, 4.0, and 16.0%, respectively. These values were significantly higher than those of persons without RP. Conclusions. Because some persons with primary RP may become typical cases of PSS within several years, a follow-up study, particulary for women who have positive titers of ANA with RP, should be carried out to find out whether the persons suffer from PSS or not. 相似文献

In order to clarify the role and interrelationship of c- myc , interleukin-2 (IL-2), and transferrin receptor (TfR) expressions on PHA-stimulated lymphocyte prohferation, we examined the effects of antisense oligodeoxynucleotides directed against c- myc , TfR, and IL-2 mRNAs on DNA synthesis and cell-cycle phase. Exposure of PHA-stimulated lymphocytes to each antisense oligomer resulted in approximately 75 80% inhibition of DNA synthesis. TfR expression was not inhibited in PHA-stimulated lymphocytes by c- myc or IL-2 antisense oligonucleotides, suggesting that the expression of c- myc , TfR, and of IL-2 is regulated by an independent mechanism. All three antisense oligonucleotides for c- myc , TfR and IL-2 synchronized mitogen-activated lymphocytes to the G1 phase as assessed by morphologic blast formation and cell-cycle phase analysis. 相似文献

A filtered QRS (fQRS) was recorded by signal averaging in 7-day-old myocardial infarction (MI) in dogs to detect late potential (LP). The criteria for the LP included a duration of fQRS (D) greater than or equal to 60 msec and a voltage in the last 15 msec (V15) less than or equal to 10 microV. These parameters were determined from the control data from 15 dogs without infarction (D: 45 to 60 msec and V15: 12.0 to 83.6 microV). On the seventh day of infarction, the D had increased from 53.5 +/- 4.7 to 62.2 +/- 9.6 msec (P less than 0.05) and the V15 decreased from 38.6 +/- 19.5 to 18.4 +/- 16.0 microV (P less than 0.01). Of 23 dogs, 14 met the LP criteria (group A) and 9 did not (group B). Sustained ventricular tachycardia (SVT) was induced in 12 group A dogs and in none of the group B dogs. The delayed epicardial activation (DEA) was recorded after the end of QRS at 5.1 +/- 4.7 sites in group A dogs and 1.3 +/- 1.8 sites in group B dogs (P less than 0.05). The maximum value of epicardial activation time was more prolonged in group A than in group B (70.0 +/- 28.3 vs 44.4 +/- 9.8 msec, P less than 0.01). The area of MI was more extensive in dogs with DEA than those without (24.9 +/- 5.8% vs 10.3 +/- 9.0% of the total left ventricular weight, P less than 0.01). In 72 of 90 sites with DEA, the thickness of the surviving epicardial muscle was less than or equal to 1 mm. The sensitivity and specificity of the criteria for LP in detecting DEA were 71.4% and 55.6%, and 100% and 81.8% for predicting inducibility of SVT. It was thus concluded that LP, reflected the DEA, was identified from infarct areas of slow conduction within a reentry circuit of SVT. 相似文献

Abstract Two cases of sleep disordered-breathing in climacteric were reported. Polysomnography including esophageal pressure (Pes) measurement was performed. Case 1 was diagnosed as upper airway resistance syndrome. Case 2 was diagnosed as obstructive sleep apnea syndrome, while many episodes of upper airway resistance also existed. Hormone replacement therapy improved clinical symptoms, and in case 1, Pes nadir was improved but incidence of arousals which was induced by breathing disturbances was not significantly changed. Sleep disordered-breathing should be suspected as a cause of sleep disorder even in females, especially in climacteric age. Pes measurement and evaluation of arousals is required. Hormone replacement therapy may release the upper airway resistance. 相似文献

Abstract Shortening of hippocampal formation (HF) in chronic schizophrenic patients have been demonstrated in our previous study. The purpose of the present study is to test if shortening of the HF occurs in schizophrenic patients suffering their initial psychotic episode. We performed contiguous, 1 mm thick, magnetic resonance imaging scans in 20 first-episode schizophrenic patients, 21 chronic schizophrenic patients, and 25 healthy subjects. Both groups of schizophrenic patients demonstrated significant shortening of the HF compared with normal controls (first-episode schizophrenia, 5.3%; chronic schizophrenia, 8.0%). However, the HF length was not significantly different between the first-episode and chronic schizophrenic patients. No significant correlation was seen between the HF length and the duration of illness in chronic schizophrenic patients. These results suggest that the HF shortening observed in schizophrenic patients may be genetic and/or developmental in origin. 相似文献
