Three hundred and seventeen recent clinical isolates were tested for in vitro susceptibility to the three cephalosporins available in India--cephalexin, cefazolin and cefotaxime by the Kirby--Bauer disc diffusion method. Cefazolin was the most effective cephalosporin against Gram positive cocci (71.8% sensitive) followed by cefotaxime (62.7%) and cephalexin (52.7%). Cefotaxime was very effective against commonly isolated Gram negative bacilli with only 10 (8.8%) isolates being resistant to it while 44 (39%) and 65 (57.5%) were resistant to cefazolin and cephalexin, respectively. All isolates of Pseudomonas aeruginosa were resistant to cephalexin and cefazolin and only 29 (32.6%) were sensitive to cefotaxime. 相似文献

Twenty patients with nodulocystic acne were randomly allocated to one of two treatment schedules: 1) Tetracycline 500 mg or 2) Tab. Gugulipid (equivalent to 25 mg guggulsterone). Both were taken twice daily for 3 months, and both produced a progressive reduction in the lesions in the majority of patients. With tetracycline, the percentage reduction in the inflammatory lesions was 65.2% as compared to 68% with gugulipid; on comparison, this difference was statistically insignificant (P>0.05). Follow-up at 3 months showed a relapse in 4 cases on tetracyline and 2 cases on gugulipid. An interesting observation was that the patients with oily faces responded remarkably better to gugulipid. 相似文献

An unexpected mortality of more than 300 cattle was investigated near a metal recovery factory located in a rural area of the Thane district of India. The factory was engaged in reclaiming lead, aluminium, tin, and zinc from discarded lead storage batteries and soft drink cans. The environmental samples (soil, leaves, grass, slag, water, and sediment), human blood and hair and animal samples (blood, urine, peritoneal fluid, liver, kidney, cow dung, ribs, and femur), collected for analysis revealed toxic levels of lead, cadmium, and chromium. Clinical examination of factory workers and school children revealed cough, fever, gastric problems, abdominal pain, skin lesions (scabies), and blue line on gums. Histopathological examination of animal tissues revealed chronic pathology with lead inclusion bodies in hepatocytes and renal tubules. Based on environmental, clinical, analytical, and histopathological observations, the mortality has been attributed to toxic levels of metals in the body and the malnourished status of the animals. 相似文献

Pancreatoblastoma or infantile pancreatic carcinoma is a rare pancreatic tumor with distinct acinar and squamoid cell differentiation that generally affects infants and young children. Ultrasound and CT scan may be useful but preoperative diagnosis is often quite difficult. The outcome is generally favourable. A such case of 10 years old boy with an abdominal mass is being presented. 相似文献

Whether blood flow during cardiopulmonary resuscitation (CPR) results from intrathoracic pressure fluctuations or direct cardiac
compression remains controversial. We developed a mathematical model that predicts that blood flow due to intrathoracic pressure
fluctuations should be insensitive to compression rate over a wide range but dependent on the applied force and compression
duration. If direct compression of the heart plays a major role, however, the model predicts that flow should be dependent
on compression rate and force, but above a threshold, insensitive to compression duration. These differences in hemodynamics
produced by changes in rate and duration form a basis for determining whether blood flow during CPR results from intrathoracic
pressure fluctuations or from direct cardiac compression. The model was validated for direct cardiac compression by studying
the hemodynamics of cyclic cardiac deformation following thoracotomy in four anesthetized, 21–32-kg dogs. As predicted by
the model, there was no change in myocardial or cerebral perfusion pressures when the duration of compression was increased
from 15% to 45% of the cycle at a constant rate of 60/min. There was, however, a significant increase in perfusion pressures
when rate was increased from 60 to 150/min at a constant duration of 45%. The model was validated for intrathoracic pressure
changes by studying the hemodynamics produced by a thoracic vest (vest CPR) in eight dogs. The vest contained a bladder that
was inflated and deflated. Vest CPR changed intrathoracic pressure without direct cardiac compression, since sternal displacement
was <0.8 cm. As predicted by the model and opposite to direct cardiac compression, there was no change in perfusion pressures
when the rate was increased from 60 to 150/min at a constant duration of 45% of the cycle. Manual CPR was then studied in
eight dogs. There was no surgical manipulation of the chest. Myocardial and cerebral blood flows were determined with radioactive
microspheres and behaved as predicted from the model of intrathoracic pressure, not direct cardiac compression. At nearly
constant peak sternal force (378–426 N), flow was significantly increased when the duration of compression was increased from
short (13%–19% of the cycle) to long (40%–47%), at a rate of 60/min. Flow was unchanged, however, for an increase in rate
from 60 to 150/min at constant compression duration. In addition, myocardial and cerebral flow correlated with their respective
perfusion pressures. Thus vital organ perfusion pressures and flow for manual external chest compression are dependent on
the duration of compression, but not on rates of compression of 60 and 150/min. These data are of course similar to those
produced by vest CPR, where intrathoracic pressure is manipulated without sternal displacement, and to those predicted for
movement of blood by intrathoracic pressure changes. These data are, however, opposite to those produced by cardiac deformation
and to those predicted for movement blood by direct cardiac compression. We conclude that intrathoracic pressure fluctuations
generate blood flow during manual CPR. 相似文献

Primary malignant lymphomas of the breast (PBL) are uncommon constituting only 0.04 to 0.53% of malignant breast neoplasms. We wish to report the clinical, cytological and histologic findings of PBL diagnosed in a 52 years old female. 相似文献

Extraskeletal chondroma is a rare entity. A fairly benign condition, it is usually seen in adults. It presents as an enlarging mass, most commonly in the hand. Local excision is the treatment of choice. We present a case of extraskeletal chondroma of hand in a 12 year male child. Its variable histological appearance not infrequently leads to a mistaken diagnosis of chondrosarcoma. 相似文献

The ability of the Vitek Yeast Biochemical Card to identify yeast isolates was compared with conventional methods. Of the fifty yeast isolates tested same species identification was obtained in thirty-four isolates. The Vitek yeast biochemical card identified 13 isolates which could not be identified by the conventional tests. Though the Vitek Yeast biochemical card gave a good rapid identification the high cost of each test severely limits its routine use in most of the laboratories. 相似文献
