The present work was aimed at developing a new colonic drug delivery system which takes advantage of the combined approaches of a specifically colon-biodegradable pectin matrix with a pH-sensitive Eudragit S polymeric coating.
The developed system was able to suitably retard the onset of drug release and to provide a colon-specific delivery, thus overcoming the problems of pectin solubility in the upper gastrointestinal tract and low site-specificity of simple pH-dependent systems.
Due to the poor compactability properties of pectin, it was used in mixture with Emdex, a hydrophilic directly-compressible material, in order to make it possible to prepare tablets by direct compression. The present study was aimed at developing a novel sodium diclofenac formulation for colonic release. The proposed delivery system consisted in a polymeric matrix tablet containing a drug central core purposely designed for obtaining a time-controlled release profile characterized by an initial phase of lag-time followed by a controlled release phase, according to zero order kinetics.
The spheric central core was formed by a solid dispersion of the drug into the hydrophilic polymer PEGwhich enabled an improvement of drug dissolution properties with respect to other carriers such as lactose.

The system, designed to exploit the relatively constant small intestine transit time, consists of a drug-containing core coated with a polymeric matrix formed by a channeling agent NaCl, mannitol, and Emdex and an inert polymer Eudragit RS The lag time was found to be dependent on type and particle size of the channeling substances used.
A walkthrough survey method was developed for measuring ambient magnetic fields MFs in industrial facilities as the first stage in hazard surveillance. This survey was designed to measure the mean and peak MF magnitudes at extremely low frequencies ELFsso that factories could be ranked by MF levels and prioritized for subsequent personal exposure monitoring.
Sixty-two facilities from 13 Standard Industrial Classifications SICs with the highest monthly electric power usage were surveyed. We carried out the study to assess, using field surveys and personal dosimetry, the potential exposure of pharmacists and pharmaceutical assistants to 60 Hz magnetic fields in a medical center of Taiwan.
Field surveys were conducted twice in the pharmacy where two workers were randomly selected and solicited to wear personal dosimetry instruments for a full-shift assessment of personal exposure. We used an EMDEX II for on site measurements and did not consider any specific instrument or equipment for health care services as potential sources of magnetic field. The effects of four directly compressible excipients such as Avicel, Dipac, Ditab and Emdex on the stability of ascorbic acid tablets were evaluated.
Ascorbic acid tablets were formulated by the direct compressive method at constant temperature and pressure. In vitro tablet properties such as weight uniformity, hardness, friability, moisture content, disintegration time and dissolution rate were evaluated. Twenty-three volunteers were solicited to wear three PEMs simultaneously; one was attached to a baseball cap worn on the head, one was attached to a band and worn around the neck positioned on the chestand one was worn in a belted pouch around the waist positioned on the right side of the hip.
The effect of PEM placement was evaluated by comparing full-shift average exposures and daily maximum or peak exposure.

EMDEX II – Low Frequency Magnetic Field Exposure System
The purpose of this study was to quantify these two occupational exposures. Magnetic fields were measured during 37 flights 23 in the cockpit and 14 in the cabin using an Emdex Lite personal dosimeter. A method is presented which links on-site electromagnetic field monitoring data with pre-existing work history data. The linkage is used to estimate cumulative and average annualized magnetic field exposure for a case-control study.
On-site electromagnetic field monitoring data for 1, volunteer utility employees, at 59 sites in the United States and three other countries, were obtained from a large project the EMDEX project designed to collect, analyze, and document Hz electric and magnetic field exposures for a diverse population. The incomplete understanding of the relation between power-frequency fields and biological responses raises problems in defining an appropriate metric for exposure assessment and epidemiological studies.
Based on evidence from biological experiments, one can define alternative metrics or effects functions that embody the relationship between field exposure patterns and hypothetical health effects. In this paper, we explore the application of the “effects function” approach to occupational exposure data.
This paper demonstrates the application of effects function analysis to residential magnetic field exposure, focusing on appliance sources and mitigation choices.
In particular, field exposure from the use of bedside clocks and electric blankets was examined. Measurements of the flux density and spectra of magnetic fields MFs generated by several types of electric bed heaters EBH were made in order to characterize the MFs to which the fetus may be exposed in utero from the mother’s use of these devices. Data on MPs were gathered from more than 1, in-home and laboratory spot measurements.
In-home measurements taken at seven different positions 10 cm from the EBHs determined that the mean flux density at the estimated position of the fetus relative to the device was 0. To define a protocol for surrogate measurement of magnetic field exposure by questionnaire, a series of spot and hour measurements was made at 50 houses in Avon, UK.
Measurements were made with Emdex II equipment in the centres of rooms with the house power encountered at the start of the visit, and then with all power to the house isolated at the main switch. The mean spot magnetic field averaged over the 50 homes for each room varied between 0. Aggregation of insulin and its prevention by carbohydrate excipients was investigated in this study.
