Male and female Swiss/ICR mice were exposed to 0.3% enflurane in air, 4 h per day, 5 days per week for 52 weeks. A control group was exposed to air alone. After 52 weeks, all animals were sacrificed and peripheral blood and bone marrow samples were examined for alterations in haemopoiesis. In general, there was no difference between treated and control groups.

AbstractTo determine the exposure to hepatitis A and hepatitis B viruses (HAV, HBV) following intravenous replacement therapy in patients with classic hemophilia and to assess the role of these viruses in persistently elevated aminotransferases, sera were studied from 136 patients from 9 months to 67 years of age who were transfused with either single‐donor cryoprecipitate (CRYO) or Antihemophilic Factor Concentrate (AHF) for periods ranging from a few months to 15 years.Serologic evidence of past or present infection with HBV was detected in 90% of all 136 patients and in 85% of those 34 patients 10 years of age or younger. Sixty‐four percent of those with serologic markers of hepatitis B had high liters of antibody to the hepatitis B surface antigen and low titers of antibody to the hepatitis B core antigen. These findings are consistent with the known high frequency of early exposure to HBV in hemophiliacs receiving replacement therapy and with recovery from these hepatitis B infections. Sixteen percent of these patients had persistently elevated aminotransferase levels; HBV could not be implicated as the cause of the enzyme elevations in most of these cases.

The judgmental policy of a group of national bank examiners in classifying commercial bank loans was identified using stepwise multiple discriminant analyses and was expressed in the form of a linear model. Credit scenarios (which were composed of both financial and non-financial cues) were presented to 24 national bank examiners at the Office of the Comptroller of the Currency (OCC) in Washington D.C. Each examiner received 20 scenarios and was asked to classify the scenarios in one of the five classifications used by the OCC. Based upon 75% of these observations, a linear discriminant model was developed using stepwise MDA analyses. The remaining observations were used to validate the model developed. Non-financial variables appeared to be important discriminators; the financial variable of industry comparison of the interest coverage ratio using cash flow was an excellent discriminatory variable; and industry comparisons and trends of financial variables appeared to be more important than the variables themselves. The model developed contained two of these variables: (a) an industry comparison of the interest coverage ratio using cash flow and (b) the trend of the debt/equity ratio. © 1980.

Eleven patients with periodontitis, ten patients with juvenile periodontitis and ten control subjects were studied to compare systemic and local immunologic responses and various other blood parameters. A more intensified immunologic response was seen in juvenile periodontitis as compared to periodontitis or controls as evidenced by: (1) greater number of plasma cells and lymphocytes in biopsy specimens of involved gingiva stained by Harris hematoxylin and eosin; (2) significant decrease in serum C4 levels and slightly elevated serum IgG levels as determined by radial immunodiffusion; (3) marked increase of positive fluorescing cells in biopsy specimens stained with antihuman immunoglobulin conjugate and an increase in complement deposition in the same tissues as determined by immunofluorescence. No significant differences among the two groups of patients and control subjects were observed with respect to complete blood counts, coagulation studies, or blood glucose levels. These findings suggest that the immunologic responses in periodontitis and juvenile periodontitis are qualitatively similar, but that the intensity of the response is greater in juvenile periodontitis.

Three units of stratified rocks are recognized: the pre-Devonian Watonga formation, composed mainly of chert and slate; the Middle Palaeozoic Touchwood formation, consisting of volcanogenic clastic sediments and andesite; and the (?)Early Permian Thrumster slate, comprising slate and metasandstone. These units have been intruded by Karikeree metadolerite dykes, serpentinite bodies and felsic dykes, and are unconformably overlain by Early Triassic conglomerate of the Camden Haven group. The Watonga formation, Thrumster slate and early members of the Karikeree metadolerite were cleaved and recrystallized under greenschist-facies conditions at an early stage during Late Permian orogenesis. Later dolerite intrusions in the cleaved rocks are massive but also show greenschist-facies assemblages. Touchwood formation rocks and associated Karikeree metadolerite dykes lack cleavage and exhibit only burial metamorphism of prehnite-pumpellyite metagreywacke facies. They were brought into contact with the more strongly deformed rocks by transcurrent movements along a system of NNW-trending faults. Subsequently, serpentinite masses rose along some of these fractures and along a younger NW-striking fault. A small thermal high, in which static recrystallization produced biotite, postdates most deformation and may be associated with a buried intrusive body. Here the serpentinite contains antigorite, in contrast with the chrysotile-lizardite serpentinites elsewhere in the block, and is associated with lenses of talc and chlorite-tremolite rocks. Fault movements continued into post-Early Triassic times.-N.C.N.S.

This zone of Palaeozoic rocks, extending some 225 km NNW from near Nundle to Warialda in NE New South Wales, includes numerous mafic-ultramafic complexes embedded in a deformed arc system. Those complexes studied in detail show features arising from both igneous processes and tectonic aggregation, the latter bringing together rocks from a variety of geological settings.-R.A.H.

Slabs of radiolarian chert up to 400 m long, and smaller blocks of limestone, andesite, basalt and siltstone are imbedded within conglomerates and sandstones of the Wisemans Arm Formation in northeastern New South Wales. Abrupt termination of individual masses, their distribution and orientation, the lack of continuity of stratification from the masses into surrounding rocks, and the presence of boulders, pebbles and sand-sized grains of identical rock types as constituents of the surrounding matrix, indicate that the masses are allochthonous, but of sedimentary origin. The matrix rocks are ill-sorted, devoid of internal sedimentary structures, and were deposited from debris flows. The olistoliths were transported within these flows. Chert olistoliths were lithified at the time of their emplacement. They were detached along bedding surfaces during periods of heightened tectonic activity that also triggered the generation of debris flows. The Wisemans Arm Formation is separated by a major fault system from a magmatic arc-fore arc basin sequence, and is more intimately related to, although also in fault contact with, rocks inferred to be deformed oceanic crust. Components of the formation were derived from both these sources at the start of or during subduction, and accumulated in the immediate vicinity of a major consuming plate boundary. © 1980.

A program package is presented for routine analysis, on a low cost minicomputer, of data obtained by flow microfluorimetry. The programs, with the aid of a graphics capability, provide calculations of various properties of cell populations: percentage of cells in various phases of the cell-cycle (G,, S, G2 + M): mean fluorescence per cell: mean narrow-angle scatter per cell, and an approximation to relative mean volume per cell from narrow-angle light scatter measurements. The system is designed to allow either direct analysis or for storage of raw data on tape files for analysis at a later time. Provision is also made for hard copy on a digital x-y plotter.

A 12.5-kilodalton protein not related to insulin or glucagon was detected in pulse-chase-labeled rat islets of Langerhans. Although this protein reacted poorly with various somatostatin antisera, analysis of two-dimensional peptide maps showed that it contains all of the tryptic fragments of somatostatin, which is located at its COOH terminus. Proteolytic conversion of the putative prosomatostatin, which took place parallel to the processing of proinsulin and proglucagon in pulse-chase experiments, coincided with the appearance of newly synthesized somatostatin and proceeded without the apparent involvement of major intermediate forms.

The possibility that enflurane defluorination is increased following treatment with isoniazid was investigated in male Fischer 344 rats. The effects of various isoniazid dosage regimens on the hepatic microsomal defluorination rates of enflurane were compared with those of several other ether anesthetics, and the conditions for production of maximal enflurane defluorination rates were determined. Seven to ten days of treatment with 50 mg/kg/day isoniazid (Nydrazid) resulted in maximal rates of defluorination of methoxyflurane, enflurane, isoflurane, and sevoflurane with no overt sign of toxicity. Compared with saline treatment of control rats, isoniazid increased defluorination of enflurane 370 per cent, methoxyflurane 259 per cent, sevoflurane 283 per cent, and isoflurane 168 per cent. Previous studies have shown that while the enzyme inducer phenobarbital increased in vitro rates of methoxyflurane defluorination approximately 1000 per cent, the rate of enflurane defluorination remained unchanged or increased by 100 per cent at most. In this study, enhanced hepatic microsomal defluorination was not associated with an increase in cytochrome P-450 per mg protein. Anesthetic defluorination rates were not altered by treatment with chlorobutanol, the preservative contained in Nydrazid.

We consider two methods of defining a regression analog to a trimmed mean. The first was suggested by Koenker and Bassett and uses their concept of regression quantiles. Its asymptotic behavior is completely analogous to that of a trimmed mean. The second method uses residuals from a preliminary estimator. Its asymptotic behavior depends heavily on the preliminary estimate; it behaves, in general, quite differently than the estimator proposed by Koenker and Bassett, and it can be inefficient at the normal model even if the percentage of trimming is small. However, if the preliminary estimator is the average of the two regression quantiles used with Koenker and Bassett’s estimator, then the first and second methods are asymptotically equivalent for symmetric error distributions. © 1980, Taylor & Francis Group, LLC.

A radiometric method for the detection of Salmonella in foods has been developed which is based on Salmonella poly H agglutinating serum preventing Salmonella from producing 14CO2 from [14C]dulcitol. The method will detect the presence or absence of Salmonella in a product within 30 h compared to 4 to 5 days by routine culture methods. The method has been evaluated against a routine culture method using 58 samples of food. The overall agreement was 91%. Five samples negative for Salmonella by the routine method were positive by the radiometric method. These may have been false positives. However, the routine method may have failed to detect Salmonella due to the presence of large numbers of lactose-fermenting bacteria which hindered isolation of Salmonella colonies on the selective agar plates.

Several preparative techniques (detergent treatment, ethanol fixation, and hypotonic cell lysis), DNA fluorochromes, and methods of numerical analysis (planimetric or curve-fitting) were compared for the estimation of cell-cycle kinetic parameters (G1, S, G2 + M) by flow cytometry. In addition, coefficients of variation (CV), relative fluorescence, and G1/chicken erythrocyte (CRBC) ratios were measured and the effects of the proportion of cycling cells and cellular RNA content were examined. DNA-fluorochromes were ranked by relative fluorescence: 4,6-diamidino-2-phenylindole > ethidium bromide/mithramycin > Hoechst 33342 > mithramycin > ethidium bromide > acridine orange ≃ propidium iodide. The first four (DNA-specific stains) gave lower CVs than the remainder (DNA intercalators). Detergent treatment also increased relative fluorescence and slightly lowered CVs. Comparable results were obtained for the kinetic parameters independently of stain or staining procedure; intercalating dyes with cells of a high RNA content not treated with RNAse and acridine orange being exceptions. Of the two methods of numerical analysis, the planimetric technique was more consistent. Although highly consistant G1/CRBC ratios were obtained for any one stain, independently of staining procedures, variations between stains were noted. It is suggested that the detergent treatment in combination with DNA-specific stains provide optimal results.
