[Examination of the fine interstitial changes of pneumoconiosis with high resolution computed tomography (HR-CT)].

High resolution CT was performed in 14 patients with fine interstitial changes of pneumoconiosis and Review image was evaluated for the diagnostic accuracy as compared with conventional chest roentgenogram. Of the 14 Patients in the study, 7 were divided category 1 by the ILO U/C classification, 4 were category 2, 3 were category 3. Studies of lung function showed obstructive ventilatory disturbance characterized by moderate reduction in FEV1.0% (58.6 +/- 16.5%) and V25/H (0.34 +/- 0.24 l/sec/m). HR-CT defined more sensitive in the presence of fine lung nodules than conventional X-p, and showed high contrast interfaces provided by the aerated lung. HR-CT was also of value in detecting bulla, bleb, peripleural changes and hilar lymphadenopathy. Radiologic-pathologic correlation was examined on the specimens of transbronchial lung biopsy in 4 patients, and revealed the diagnostic usefullness of HR-CT.

[A case of sarcoidosis with marked bronchial involvement].

Bronchial mucosal biopsy is considered to be a useful procedure for the diagnosis of sarcoidosis in Europe and the USA. However, bronchial involvement of sarcoidosis has seldom been reported in Japan. We report an interesting case of sarcoidosis with marked bronchial changes. A 40-year-old symptom free women visited our hospital to seek a diagnosis concerning a diffuse reticulonodular shadow in her chest X-ray film. Bronchofiberscopy showed multiple nodules, yellow white plaques and hypervascularity of the thickened edematous mucosa with severe stenosis and deformity of the lober or segmental bronchi. Bronchial mucosal biopsy as well as TBLB revealed typical non-caseating epithelioid granulomas. A pulmonary function test showed restrictive ventilatory disturbance with impaired diffusing capacity and small airway dysfunction. After corticosteroid therapy, bronchial mucosal changes disappeared and chest radiological and pulmonary function abnormalities were improved. After reviewing the bronchofiberscopic findings of 11 cases of sarcoidosis, we found bronchial mucosal changes in 8 cases. Bronchial mucosal biopsy should be regarded as an important procedure for the diagnosis of sarcoidosis.

Diffuse peripheral lung disease: evaluation by high-resolution computed tomography.

High-resolution computed tomography (HRCT) was performed on 15 patients who had diffuse peripheral lung disease, and the findings were compared with those of conventional chest radiography and histologic examination. Bullae, interstitial fibrosis with honeycombing, and small granulomas were more clearly and specifically demonstrated on HRCT scans than on conventional chest radiographs in all patients. Histologically proved mild alveolar wall thickening due to alveolitis in cases of sarcoidosis and systemic lupus erythematosus was not detected. HRCT is useful for performing detailed morphological analyses of abnormalities of the peripheral portions of the lung.

[Penetration of cefmenoxime into pleural fluid].

Single doses of cefmenoxime (CMX), 1 g intravenous drip infusion, were administrated to 5 patients with pleural effusion. The study group consisted of 3 men and 2 women, aged 38 to 69 years (mean 54.8 years); 4 had carcinoma with pleural effusion and 1 had SLE. Pleural fluid and serum samples were taken at intervals 1 to 24 hours for determination of CMX levels. The following results were obtained: Intravenous drip infusion of 1 g CMX yielded a peak pleural concentration of 4.5 micrograms/ml after 2 hours and pleural levels over 3 micrograms/ml were maintained for 5.5 hours after intravenous drip administration. Ratio maximum pleural concentration to peak serum level reached 15.0 +/- 8.3% at 2 hours after intravenous drip administration.

Monocrotaline-induced renal lesions.

Monocrotaline, an alkaloid obtained from Crotalaria spectabilis, provides an experimental model for studies of mesangiolysis as seen in Habu venom poisoning and hemolytic-uremic syndrome. Renal lesions induced in rats by a single intraperitoneal administration of monocrotaline were examined by light and electron microscopy. Two weeks after the injection glomerular capillaries showed focal endothelial cell detachment and adhesion of platelets to the basal lamina. At 3 weeks there was no endothelial denudation but the mesangium was severely edematous. Mesangiolysis occurred at 4 weeks, accompanied by dilatation or obliteration of capillaries and necrosis and hemorrhage in the mesangium. Insudation of plasma constituents facilitated by the endothelial injury appeared important in the pathogenesis of mesangiolysis. Fusion of capillaries seemed to lead to capillary aneurysmata and necrosis of the mesangium. These glomerular lesions induced by monocrotaline were similar to those of Habu venom poisoning or hemolytic-uremic syndrome.

[Clinical experience with cefoperazone in respiratory tract infections and studies on its penetration into pleural effusion].

Patients with bronchopulmonary infections were treated with cefoperazone (CPZ), and the serum and pleural effusion concentrations were determined after 2g CPZ drip infusion. The following results were obtained: Eight of 10 patients treated with CPZ responded with a significant clinical improvement. Side effects were found in 4 cases; eruption in 1 case, fever and granulocytopenia in 1 case, elevation of GPT in 1 case, and thrombocytopenia in 1 case. But these side effects disappeared immediately after cessation of CPZ treatment. Intravenous drip infusion of 2 g CPZ yielded a peak serum concentration of 112.0 --210.0 micrograms/ml immediately after the end of drip infusion, and a peak pleural effusion concentration of 8.8--43.0 micrograms/ml at 2--6 hours after the end of drip infusion. The ratio of peak pleural effusion concentration to peak serum concentration was 4.4--26.9%.

[Clinical studies on cefmetazole in respiratory infections].

Cefmetazole (CMZ) was used for the treatment of respiratory infections in 10 cases; six cases of bronchopneumonia, 2 cases of acute exacerbation of chronic pulmonary emphysema or bronchitis disease, 1 case of acute exacerbation of chronic respiratory failure and 1 case of lung abscess. CMZ was administered by intravenous drip infusion at a daily dose of 2 to 4 g for 5 to 24 days. Intramuscular injection of gentamicin was combined in 2 cases. Clinical results were as follows; excellent in 6 cases, good in 2 cases, fair in 1 case and poor in 1 case. As to the side effects of the drug, allergic reaction with fever and eosinophilia was observed in 1 case. This side effect disappeared immediately after cessation of CMZ. In view of the above, CMZ may be considered to be a clinically useful antibiotic against respiratory infections.

Increased alveolar-capillary membrane permeability by monocrotaline.

To study the effect of monocrotaline on the pulmonary alveolar-capillary membrane permeability, cardiac catheterization, extravascular lung water content and absorption of 14C-compounds from the rat lungs in combination with morphological observations were studied in the early stage of monocrotaline intoxications. Purified monocrotaline or its pyrrole was administered to rats with various doses. Single dose of 50 mg/kg of monocrotaline was enough to induce pulmonary hypertension 4 weeks later, but neither immediate nor direct pressor effect was observed by monocrotaline or active pyrrole. Only 3 to 5 mg/kg of pyrrole was enough to produce alveolar flooding with increased extravascular lung water content and accelerated absorption of 14C-mannitol and 14C-inulin from lungs 24 hours after administration. In contrast with fast and potent effect of pyrrole, effect of monocrotaline was mild and delayed in development. These findings suggested that monocrotaline increased the porosity of not only endothelial but also alveolar membrane by active metabolite.
