Implications of the Java language on computer-based patient records.

The growth of the utilization of the World Wide Web (WWW) as a medium for the delivery of computer-based patient records (CBPR) has created a new paradigm in which clinical information may be delivered. Until recently the authoring tools and environment for application development on the WWW have been limited to Hyper Text Markup Language (HTML) utilizing common gateway interface scripts. While, at times, this provides an effective medium for the delivery of CBPR, it is a less than optimal solution. The server-centric dynamics and low levels of interactivity do not provide for a robust application which is required in a clinical environment. The emergence of Sun Microsystems' Java language is a solution to the problem. In this paper we examine the Java language and its implications to the CBPR. A quantitative and qualitative assessment was performed. The Java environment is compared to HTML and Telnet CBPR environments. Qualitative comparisons include level of interactivity, server load, client load, ease of use, and application capabilities. Quantitative comparisons include data transfer time delays. The Java language has demonstrated promise for delivering CBPRs.

[Influence of progressive systemic sclerosis on gastric emptying].

Gastric motility was measured with an isotopic method in patients with progressive systemic sclerosis (PSS). Twenty-six women aged 48 +/- 10 yr with PSS were investigated. The duration of PSS prior to the study ranged from 2 to 25 yr. Control values were obtained from 12 healthy female volunteers aged 34 +/- 8 yr. Endoscopic examination was carried out in all investigated individuals to exclude abnormalities that were non-related to PSS. Measurements were done at morning, after an overnight fast. Patients and controls received a test meal of 1650 kJ containing human albumin microspheres labelled with 7.4 MBq of 99mTc. Subjects were investigated with a gamma-camera. It was shown that gastric emptying (GE) t 1/2 was delayed in the patient with PSS (289 +/- 325 min) as compared to the controls (92 +/- 19 min), p < 0.001. Delayed t 1/2 over x + 2SD of the control group was found in 69% of patients with PSS while in the control group O. The mean transit time (MTT90) was in the PSS group significantly longer than in the control group, 42.3 +/- 1.4 and 40 +/- 0.9 min respectively (p < 0.001). There was no correlation found between GE t 1/2 and the time of PSS duration (r = 0.08), its type II or III as well as the titer of Scl-70 antibodies in blood serum (r = 0.29, p > 0.1).

Effect of isoprenaline on tissue elastin content and serum elastolytic activity in normal and hydrazinophthalazine-treated rats.

Cardiomyopathy was produced by isoprenaline injections to healthy and hydrazinophthalazine-treated rats. The elastin content in the heart muscle and the aortic wall as well as the level of serum elastolytic activity were determined. An increase of elastin content in both tissues was found, and its progress was concomitant with the development of isoprenaline injury. It was also found that the elastolytic activity increased on the second day after the last isoprenaline injection, and on the seventh day of the experiment it began to decrease. Changes in hydrazinophthalazine-treated rats after dosing them with isoprenaline had a similar tendency but they were significantly lower than those found in healthy animals receiving isoprenaline only.

Effect of some selected anti-inflammatory steroids on elastin content in liver of rats treated with carbon tetrachloride.

Hepatic fibrosis was induced in rats by poisoning them with carbon tetrachloride. The influence of anti-inflammatory steroids (hydrocortisone, prednisone, dexamathasone) upon elastin content in liver was investigated in healthy and CCl4 intoxicated rats. An increase of liver elastin content was observed in animals with CCl4-induced hepatic fibrosis Opposite results were obtained in normal rats after treating them with glucocorticosteroids. A decrease of elastin content after steroid treatment was also found in rats with injured liver, as compared to animals receiving CCl4 only. Presumable mechanisms of the results are discussed.
