OBJECTIVE Poor oral hygiene and dental health are very common among the institutionalized elderly. The purpose of this study was to evaluate the association of apraxia with oral hygiene and/or health. MATERIALS AND METHODS Ninety-two residents of 13 long-term care homes in southwest Germany participated in the study. For each participant, ideomotor(More)
In a set of 154, and/or 260 ejaculates, collected from 72 boars, a relationship was studied between the activity of aspartate aminotransferase (AST) in seminal plasma and sperm concentration, and/or percent occurrence of morphologically abnormal spermatozoa. We failed to demonstrate any relation between the AST activity and sperm concentration (r = 0.023; P(More)
BACKGROUND/AIMS Mild cognitive impairment (MCI) is a frequent syndrome in the older population, which involves an increased risk to develop Alzheimer's disease (AD). The latter can be modified by the cognitive reserve, which can be operationalized by the length of school education. MCI can be differentiated into four subtypes according to the cognitive(More)
Thirty-three boars with sexual dysfunctions and twenty-six boars clinically sound as to their reproductive capacity were evaluated for the testosterone levels in the blood plasma before i.v. administration of 500 i.u. of chorionic gonadotropin and two hours after the administration. A group of animals with reproduction disorders comprised boars with an(More)
In intact boars, intravenous administration of 100 to 6000 I. U. chorionic gonadotropin elicited a pronounced rise in the plasma level of testosterone, depending on the time interval from the administration of chorionic gonadotropin and on the size of the administered dose. In the blood of castrated boars such an application of choronic gonadotropin did not(More)
The levels of eleven biochemical parameters were determined in the blood serum of 150 healthy breeding boars of the Large White, Landrace and Duroc breeds from three A. I. stations. The following average values were obtained: calcium 1.94 +/- 0.42 mmol . l-1 with a statistically significant difference of the means between the LW and L breeds, phosphorus(More)
In two sexually mature boars subjected to bilateral vasectomy the content of testosterone was followed in the semen and blood plasma prior to the operation and in the course of 26 days after the operation. In the third boar only the operation without actual vasectomy as the control was made to eliminate the possible effect of narcosis and of the surgical(More)
Bilateral orchidectomy caused a marked decrease in the concentration of testosterone in the bood plasma of boars already in the early post-castration stage of three hours after the operation. In the period from 3 to 207 days after castration, the pre-operation levels of plasma testosterone decrease by 84.4%, on an average. Adreno-cortical compensation of(More)
