Prior to 1972, a variety of operations were performed to treat rotator cuff pain. Neer in 1972 recommended an anterior acromioplasty, which quickly became the standard of care based on Level IV and Level V evidence. In 1987, Ellman offered an arthroscopic approach to performing the acromioplasty; since then Level I studies have been conducted to assess the success of the arthroscopic approach. ...

1. A rapid colorimetric and apparently specific micromethod for the determination of total glutathione in small amounts of tissue is described. Generally, less than 30mg. of tissue is sufficient and this is homogenized in ice-cold 3% metaphosphoric acid. The product is filtered through sintered glass and neutralized or diluted before being added to a cuvette containing phosphate buffer, pH7.1, ...

OBJECTIVE Comparison of two types of tonsil surgery for 16- to 25-year-old patients, with respect to primary morbidity, snoring, and recurrent infections after 1 year. Teenagers and young adults are a significant proportion (26%) of the population that receive tonsil surgery each year and appear to suffer more pain than younger children. Recurrent tonsillitis, in combination with obstructive pr...

Among the pathologic hypotheses of Alzheimer’s disease (AD), cholinergic deficit and oxidative stress have been implicated as two major hallmarks. Therefore, inhibition of cholinesterase and oxidation are the two promising strategies in the development of a drug for AD. Thunbergia grandiflora leaf extract (TGEx) is used in this research to investigate its anticholinesterase and antioxidant pote...

Purpose of the study . Evaluation antioxidant status and DNA damage in tissues subcutaneous xenografts non-small cell lung cancer peritumoral created using A549 H1299 cultures. Materials methods The included 35 intact male Balb/c Nude immunodeficient mice. Cell lines were used as transplantable tumor biomaterial. A CDX model was accordance with protocol for supratentorial injections (Ozawa T., ...

Two unusual variants of cholinesterase (acylcholineacylhydrolase, 3.1.1.8) have been recognized by the use of differential inhibitors (Kalow and Genest, 1957; Harris and Whittaker, 1961). A third variant, the silent gene, determines an absent or greatly reduced serum cholinesterase level in the affected homozygote (Liddell, Lehmann, and Silk, 1962). These variants are alleles, and the affected ...

OBJECTIVE In chronic hemodialyzed (CH) patients the balance between production of reactive oxygen species and antioxidant defense system is disturbed and shifted towards oxidative conditions. The properties of albumin in CH patients were studied before hemodialysis (HD) and post-HD. METHODS Two oxidants were applied, organic t-butyl hydroperoxide (t-BOOH) and inorganic hydroperoxide (H2O2), f...

The effect of different L-phenylalanine (Phe) concentrations (0.1-12.1 mM), on acetylcholinesterase (AChE) and Na+,K(+)-ATPase activities of brain homogenate and pure enzymes, was investigated at 37 degrees C. AChE and Na+,K(+)-ATPase activities were determined according to Ellman G. L., Courtney D., Andres V. and Featherstone R. M. (1961), Biochem. Pharmacol. 7, 88-95 and Bowler K. and Tirri R...

BACKGROUND Lyme borreliosis is a tick-transmitted, chronic, zoogenous disease caused by Borrelia burgdorferi spirochete. The clinical picture of Lyme disease is characterized by the variety of tissue and organ involvement and differing severity of symptoms. One of the pathogenic symptoms of early Lyme disease is a skin lesion called erythema migrans. MATERIAL AND METHODS The purpose of our re...

In 1943 Henrik Sj6gren first described the syndrome which bears his name. It is generally recognized that the diagnosis can be made when any two of the following three features are present: xerostomia with or without salivary gland enlargement, keratoconjunctivitis sicca, and connective tissue disease, usually rheumatoid arthritis (Bunim, 1961; Bloch and Bunim, 1963). The xerostomia and keratoc...
