Abstract
With the increasing manufacture of expensive systems for the measurement of ambulatory blood pressure there is a need for potential purchasers to be able to satisfy themselves that the systems have been evaluated according to agreed criteria. The British Hypertension Society has, therefore, drawn up a protocol of requirements for the evaluation of these devices. This protocol incorporates many features of the American National Standard for Non-Automated Sphygmomanometers but includes many additional features, such as strict criteria for observer training, interdevice variability testing before and after a month of ambulatory use, and a new system of analysis which permits the test system to be graded. It is recommended that manufacturers of ambulatory blood pressure measuring devices should obtain an unbiased evaluation according to a recognized standard before a device is marketed.

Abstract
Meningiomas are one of the most common nervous system tumors in dogs. They are mostly solitary, benign, intracranial tumors of the transitional type. Tentative diagnosis can usually be made on historical data, clinical and neurological signs, and radiographs, with an antemortem diagnosis confirmed by exploratory surgery and histologic evaluation of biopsy. The literature contains many reports of the gross, histological and ultrastructural morphology of canine meningiomas, but little on the cytologic features of these tumors. This report describes the cytologic appearance of an intracranial meningioma in a 9-year-old Miniature Schnauzer.

Abstract
The B cell surface Ig molecule plays an important regulatory role in delivering inductive/tolerogenic signals to the cell. In this paper, the effect of Ag and anti-idiotopic antibodies on the in vitro proliferation and Ig secretion of a B cell tumor was studied. The tumor (BCL1), which had been transfected with the TEPC-15 VH and VL Ig genes, expresses surface Ig and secretes antibody that binds the hapten phosphorylcholine. We found that Ag (C polysaccharide and phosphorylcholine carrier Ag) and two different anti-idiotopic antibodies, in the absence of T cells, all inhibited the proliferation of the T15+ transfectant cell line. The anti-idiotopic antibodies, but not Ag, also inhibited the secretion of T15 Ig by this cell line, suggesting different functional roles for Ag vs anti-Id in the regulation of B cell inactivation. The inhibition of secretion and proliferation appears to be cell cycle phase related. In addition, mouse rIL-4 could override the inhibition of proliferation induced in these studies. These phenomena, demonstrating that binding of surface Ig can result in the transduction of negative growth signals to a B cell tumor, can be viewed as a manifestation of immunologic tolerance. These findings collectively demonstrate that Ag and anti-Id mediate different signals to B cells via interaction with the surface Ig. Because of the monoclonal nature of the T15 transfectant and the anti-idiotypic antibodies, this system can be used to investigate the underlying molecular reactions involved in the B cell response and induction of tolerance.

Abstract
MR was performed on six patients clinically diagnosed as having neurofibromatosis. Owing to its multiplanar capability, MR greatly helped determine the extent of visual pathway disease. We attempted to find specific optimal pulse sequences for evaluating the prechiasmatic, chiasmatic, and retrochiasmatic visual system at 0.35 T. Using spin-echo techniques, we evaluated a T1-weighted sequence (TR 300 msec/TE 35 msec), an intermediate T2-weighted sequence (TR 1500 msec/TE 35 msec), and a T2-weighted sequence (TR 1500 msec/TR 70 msec). We found that the orbital and intracanalicular optic nerves were most accurately and easily seen with the T1-weighted sequence axially and coronally; the chiasm was best seen with the intermediate T2-weighted coronal sequence; and the retrochiasmatic visual pathway was optimally evaluated with T2-weighted spin-echo technique.

Abstract
The Avionics Pressurometer III is the only noninvasive indirect ambulatory blood pressure system which provides 24-h blood pressure measurements, but it has been subjected to limited evaluation. We report a critical evaluation comparing it to simultaneous intra-arterial blood pressures both at home and at hospital as well as during standardized exercise. Comparisons with simultaneous indirect methods were also made. Twenty-two hypertensives undergoing intra-arterial ambulatory blood pressure monitoring wore the two recorders for one day. The mean difference (standard deviation SD) for intra-arterial blood pressure--Avionics blood pressure was 2 (SD 8.6)/-14 (SD 10.3) mmHg at home and -3 (SD 15.4)/-11 (SD 12.3) mmHg at hospital. At the end of exercise the figures for the same comparison were -7 (SD 16)/0 (SD 15.6) mmHg. In general the agreement between intra-arterial and Avionics pressurometer recordings was closer for systolic than for diastolic blood pressures but there was wide variation for individuals as shown by the standard deviations about the mean difference. We did not use the recorder at night as patients complained that the noise kept them awake and so night-time blood pressures were not attainable. We do not think the recorder performed satisfactorily during physical exertion, and in view of its expense, this recorder is of limited potential value in supplying accurate information.

Abstract
An endodeoxyribonuclease, designated CreI, was purified 16,000-fold from zygotes of the eukaryote Chlamydomonas reinhardtii. CreI preferentially attacks the sequence TATA producing double strand breaks with 3'-phosphomonoester and 5'-hydroxyl termini. The endonuclease has an Mr = 27,000 and requires Ca2+ at pH 7.5 for optimal activity.

Abstract
High response rates have been reported with hepatic intra-arterial infusions of floxuridine in patients having colorectal carcinoma metastatic to the liver. The major toxicity of this therapy has been described as "chemical hepatitis." In a randomized trial of intravenous v intra-arterial floxuridine, we observed that all 35 patients receiving intra-arterial therapy developed significant increases in alkaline phosphatase and, in some cases, serum glutamic oxaloacetic transminase and/or bilirubin. Seven patients receiving intra-arterial therapy were studied with cholangiography which, in all cases, demonstrated sclerosis of the intrahepatic and/or extrahepatic bile ducts. In addition, liver biopsies showed cholestasis and pericholangitis with minimal hepatocyte damage. These findings suggest that "biliary sclerosis" rather than "chemical hepatitis" is the predominant toxicity associated with hepatic intra-arterial infusions of floxuridine.

Abstract
In the 1980s the convergence of a number of factors is causing government at all levels, industry, and labor to plan or initiate major reductions in health spending. Important among these are rising health care costs, a troubled national economy, mounting federal deficits and state revenue shortfalls, and the philosophical course and domestic policy of the Reagan administration. In this context government has been rethinking its capacity to finance health services for the poor, and new and sometimes controversial arrangements for delivering these services are being developed. The dilemma government officials face now is how to cut costs while still assuring that quality medical services are available. This article focuses on what these new policy developments and arrangements are and whether the significant gains in access and in health achieved over the past 20 years will be sustained. Because truly sweeping reforms are unlikely, whether government will maintain earlier commitments and established arrangements for financing and delivering health services to the poor will be worked out piecemeal over the next several years.

Abstract
This study explored the usefulness of archival data in predicting rural health care utilization. A regression model was used to see how well observed utilization for local populations could be predicted by calculating expected values in advance from age- and sex-specific national rates applied to local age and sex profiles. Although the correlation between observed and expected utilization was reasonably high (r = 0.92), an attempt was then made to improve prediction by considering other data that do not require independent collection. These archival data included indicators of historic utilization (local Medicaid payments, the percentage of births to county residents occurring in the mother's county of residence, percentage of children immunized, and infant mortality) and services already available. Observed utilization data were obtained by surveys in eight rural counties, and the predictor was tested on three additional rural communities. A predictor equation that added to the expected utilization only one variable (the percentage of births to county residents occurring in the mother's county of residence) was found to account for approximately 95% of the variance in observed utilization. This predictor is recommended for planners who need convenient, low-cost market feasibility estimates for proposed project sites and a way to establish intermediate goals or incentives during early project development.

Abstract
1 The hypotensive action of labetalol was evaluated during 24 h by continuous intra-arterial ambulatory monitoring in 14 patients. The dose used ranged from 300--1800 mg daily. 2 The drug caused a significant reduction of systolic BP in 19 and diastolic BP in 20 of the 24 h of monitoring. Heart rate was also reduced but less markedly than BP. 3 The rapid early morning increase in BP was also effectively controlled. 4 The mild pre-waking increase in BP was not significantly reduced. 5 Labetalol treatment reduced the variation in systolic BP from the lowest observed quarter-hourly mean as compared with pre-treatment values. 6 The quarter hourly mean values were consistently smooth and revealed no sudden variations which might have resulted from postural hypotension.
