chronic obstructive pulmonary disease (copd) has been defined by the global initiative for chronic obstructive lung disease (gold), as a disease state characterized by airflow limitation which is not fully reversible. copd consists of emphysema which is the destruction and inflammation of the lung alveoli. adenosine deaminase (ada, e.c.3.5.4.4) converts adenosine to inosine. there are two isoen...

purpose : to investigate intraocular pressure (iop) changes due to different serum level heights by using tonopen in acquired globes from the iran eye bank (ieb). methods : in this interventional prospective case series, serum were infused into 18 normal globes acquired from ieb by using 21g needle inserted in vitreal space through optic nerve head to change the iop by different fluid level hei...

background : ruptured cerebral aneurysms (icas) are the most common non-traumatic cause of subarachnoid hemorrhage (sah) that is associated with life threatening complications such as vasospasm, infarction, and hydrocephalus (hcp). the active participation of macrophage/monocyte-mediated inflammatory response in the pathogenesis of cerebral aneurysm as labeled with monocyte chemoattractantprote...

The immunological cross-reaction among sulfocephalosporins (cefsulodin, SFC-I, SFC-II), cephaloridine, sulbenicillin, penicillin G and 7-aminocephalosporanic acid has been investigated. A specific antibody was produced in rabbits against several structurally related haptens. The sensitization was conducted with a hapten-human serum albumin conjugate, which was prepared in an alkaline solution, ...

The susceptibility of 10 multiply antibiotic-resistant strains of Streptococcus pneumoniae to several quinoline antibiotics and to coumermycin, novobiocin, and penicillin was determined. The MIC of penicillin for all test isolates was greater than or equal to 4 micrograms/ml. Ciprofloxacin was the most active quinoline derivative tested, followed by norfloxacin. These isolates of S. pneumoniae ...

Purpose: To investigate the effect of combination benzathine penicillin and ceftriaxone in treatment latent syphilis elderly. 
 Methods: A total 70 elderly patients with treated First People’s Hospital Yichang from March 2020 to 2021 were enrolled this study. Control group (CG) comprised thirty-two penicillin, while 38 received placed study (SG). Therapeutic efficacy adverse reactions both...

Clindamycin palmitate and potassium phenoxymethyl penicillin were evaluated in 103 children with upper respiratory illnesses and pharyngeal group A streptococci, from November 1970 to July 1971. The children were assigned randomly by weight to one of the antibiotic regimens given orally for 10 days. Clindamycin palmitate and potassium phenoxymethyl penicillin dosages were 75 and 125 mg, respect...

A series of step-level penicillin-resistant derivatives of Streptococcus sanguis V288 (Challis) were obtained through successive genetic transformations. The DNA donor used was a laboratory-derived, penicillin-resistant multistep mutant of the recipient strain. Detection of the penicillin-binding proteins (PBPs) of wild-type and transformants revealed five major PBPs. While it was found that S....

Abstract— Fifteen protein conjugates of penicillins and cephalosporins containing amino- and/or carboxylic groups in the initial structures have been synthesized reactions with human serum albumin or ovalbumin using 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride (EDC) a combination EDC N -hydroxysulfosuccinimide at various ratios base reagents. A comparative study composition prope...

The pharmacokinetics and bacteriological efficacies of penicillin G, ceftriaxone, vancomycin, and imipenem were determined in rabbits with experimental meningitis caused by Streptococcus pneumoniae strains with different penicillin susceptibilities. Drug dosages were adjusted to attain peak concentrations in serum that were similar to those observed in infants and children. In animals infected ...
