Abstract
Short of a liver biopsy, hepatic disease and drug-induced liver injury are diagnosed and classified from clinical findings, especially laboratory results. It was hypothesized that a healthy hepatic dynamic equilibrium might be modelled by an Ornstein–Uhlenbeck (OU) stochastic process, which might lead to more sensitive and specific diagnostic criteria. Using pooled data from healthy volunteers in pharmaceutical clinical trials, this model was applied using maximum likelihood (ML) methods. It was found that the exponent of the autocorrelation function was proportional to the square root of time rather than time itself, as predicted by the OU model. This finding suggests a stronger autocorrelation than expected and may have important implications regarding the use of laboratory testing in clinical diagnosis, in clinical trial design, and in monitoring drug safety. Besides rejecting the OU hypothesis for liver test homeostasis, this paper presents ML estimates for the multivariate Gaussian distribution for healthy adult males. This work forms the basis for a new approach to mathematical modelling to improve both the sensitivity and specificity of clinical measurements over time.

Abstract
Six dogs with partial seizures or partial seizure-like activity were treated with the antiepileptic drug felbamate between 1993 and 1998. All dogs had a history and results of diagnostic testing suggestive of either primary (idiopathic) or occult secondary epilepsy. Dogs ranged between four months and eight years of age at the onset of seizure activity. The median time period between onset of the first seizure and the start of felbamate therapy was 3.8 months (range 0.75 to 36 months). Median duration of therapy was nine months (range two to 22 months). All dogs experienced a reduction in seizure frequency after felbamate administration. Median total number of seizures post-treatment was two (range 0 to 9). Two dogs had an immediate and prolonged cessation of seizure activity. Steady-state trough serum felbamate concentrations measured at two weeks, and one, 12 and 22 months after the commencement of therapy in four dogs ranged between 13 and 55 mg/litre (median 35 mg/litre). Reversible haematological adverse effects were detected in two dogs, with one dog developing concurrent keratoconjunctivitis sicca. These results suggest that felbamate can be an effective antiepileptic drug without life-threatening complications when used as monotherapy for partial seizures in the dog.

Abstract
We show that an applied electric field in which the polarity is reversed every 15 minutes can improve the outcome from severe, acute spinal cord injury in dogs. This study utilized naturally injured, neurologically complete paraplegic dogs as a model for human spinal cord injury. The recovery of paraplegic dogs treated with oscillating electric field stimulation (OFS) (approximately 500 to 600 microV/mm; n = 20) was compared with that of sham-treated animals (n = 14). Active and sham stimulators were fabricated in West Lafayette, Indiana. They were coded, randomized, sterilized, and packaged in Warsaw, Indiana, and returned to Purdue University for blinded surgical implantation. The stimulators were of a previously unpublished design and meet the requirements for phase I human clinical testing. All dogs were treated within 18 days of the onset of paraplegia. During the experimental applications, all received the highest standard of conventional management, including surgical decompression, spinal stabilization (if required), and acute administration of methylprednisolone sodium succinate. A radiologic and neurologic examination was performed on every dog entering the study, the latter consisting of standard reflex testing, urologic tests, urodynamic testing, tests for deep and superficial pain appreciation, proprioceptive placing of the hind limbs, ambulation, and evoked potential testing. Dogs were evaluated before and after surgery and at 6 weeks and 6 months after surgery. A greater proportion of experimentally treated dogs than of sham-treated animals showed improvement in every category of functional evaluation at both the 6-week and 6-month recheck, with no reverse trend. Statistical significance was not reached in comparisons of some individual categories of functional evaluation between sham-treated and OFS-treated dogs (ambulation, proprioceptive placing); an early trend towards significance was shown in others (deep pain), and significance was reached in evaluations of superficial pain appreciation. An average of all individual scores for all categories of blinded behavioral evaluation (combined neurologic score) was used to compare group outcomes. At the 6-month recheck period, the combined neurologic score of OFS-treated dogs was significantly better than that of control dogs (p = 0.047; Mann-Whitney, two-tailed).

Abstract
Experimental intravenous challenge of 8-week old cats with the Maryland isolate of feline immunodeficiency virus, Maryland isolate (FIV-MD) was investigated for its effects on cognitive and behavioral function at 12 months postinfection. Six cats infected with FIV-MD were compared with age-matched controls on several behavioral measures. These measures included an open field observation, locomotion tests, traversing planks of various widths for food reinforcement, and a spatial learning task. No group differences were observed on any measure of locomotion. Differences were present with exploratory and stationary activity in the open field observation, with infected cats exhibiting higher levels of exploratory activity and in less stationary activity compared with that of control cats. In the plank-walking experiment, infected cats were less able to successfully cross progressively narrower planks compared with control animals. A holeboard paradigm was constructed to test spatial learning and memory, in which cats were required to locate food reinforcement based on position in the holeboard array. As a group, FIV-infected cats committed more reference (exploring an unbaited cup) and working memory (returning to a previously visited baited cup) errors than control cats. The main difference demonstrated was a higher activity level and associated distractibility in FIV-infected cats that appears to be related to their overall deficient performance when learning new tasks. These results indicate that behavioral function is altered and cognition is quantitatively impaired in FIV-infected cats.

Abstract
Plasma diagnostics results of electron densities and gas temperatures in commercial low-pressure deuterium lamps at current densities from 38 A/cm(-2) to 306 A/cm(-2) are presented. These plasma parameters are obtained by comparing measured and calculated Balmer line profiles, taking into account Stark broadening, Doppler broadening, and the influence of fine structure and the apparatus profile. Results for the plasma spot show a steady increase of electron density from 1.6 x 10(13) cm(-3) to 5.0 x 10(13) cm(-3) and of gas temperature from 1800 to 6800 K.

Abstract
The inhibitory capacity of pyrophosphate, citrate, magnesium and chondroitin sulphate was investigated, using the urine of 21 calcium oxalate stone-forming patients without metabolic alterations. The inhibitory effect of these substances was assessed by a combination of nephelometry (light scattering) and optical microscopy. The results showed that citrate and magnesium had an inhibitory effect in a significant number of cases. Pyrophosphate and chondroitin sulphate had a less marked effect. The main urinary lithogenic biochemical parameters of the patients were also studied to see if there was a relationship between them and the inhibitory capacity of the compounds.

Abstract
Opinions vary on the effects produced by urinary inhibitors of crystallisation. We describe a simple method for studying inhibitory effects in urine based on nephelometry and optical microscopy. It was concluded that the inhibitory effect of a given substance on calcium oxalate crystallisation depends on the particular sample of urine being examined and that the most effective inhibitor can be determined only by studying the urine of each patient individually.
