Abstract
A new and specific tissue kallikrein-binding protein was identified in mammalian serum and in secreted transformed-cell culture media (Chao et al., Biochem. J. 239: 325-331, 1986). We have designated this kallikrein-binding protein as "kallistatin". Human kallistatin has been purified from serum, using chromatographic steps including DEAE-Sephadex, hydroxylapatite, Cibacron blue-Sepharose, Sephacryl S200, and preparative polyacrylamide gel electrophoresis. The purified kallistatin consists of a single polypeptide chain with an apparent molecular weight of approximately 54 kDa and isoelectric point of approximately 5.0. Kallistatin was eluted as a single peak on reverse-phase HPLC. The purified kallistatin and 125I-labelled human tissue kallikrein form a approximately a 92 kDa SDS- and heat-stable complex. The complex formation is pH dependent and is inhibited by 0.1% (W/V) of deoxycholate or SDS but not by 0.5% (W/V) of Triton X-100, digitonin, Lubrol or CHAPS. A approximately 54 kDa protein was identified in partially purified kallistatin by polyclonal anti-kallistatin antibodies in Western blot analysis and by its binding to 125I-labelled-human tissue kallikrein in ligand blotting. The role of kallistatin in regulating tissue kallikrein activity and metabolism may now be evaluated.

Abstract
The response of single detergent treated bovine retinal pigment epithelial cells in culture to ATP was measured with an image analyser. The most pronounced contraction was produced by 1.0 mM ATP with most change taking place in the first 10 min. At 1 h the area had decreased by about 33%, perimeter 22% and maximum length 25%. By way of comparison rabbit skin fibroblasts had a decreased area of approximately 40%, perimeter 25% and maximum length 22%. Bovine aortic smooth muscle cells on the other hand decreased in area by 55%, perimeter 40% and maximum length 36%. It is hoped that this assay may be used to evaluate drugs which could counteract contractile events in proliferative vitreoretinopathy.

Abstract
A program of 8 lessons on various aspects of osteoarthritis (OA), its treatment, and patient self-care was prepared on an Apple IIc computer. The courses were then field-tested and evaluated by 72 older (age range 52-88) OA patients in community centers for senior citizens. Statistical analysis of the findings showed significant increases in knowledge and significant self-reported, beneficial behavior changes, including increased exercise, use of heat, and rest. Our findings demonstrate that older persons can use the computer to learn to cope with OA when a thoughtfully planned program is made available in a community setting.

Abstract
Progressive hypersomnia, memory disturbance, and vertical ophthalmoplegia developed in a 63-year-old woman. The diagnosis of Whipple's disease of the central nervous system was suggested by her presentation and results of studies using magnetic resonance imaging. Despite a one-month course of antibiotics, active Whipple's disease, localized to the central nervous system, was found at autopsy.

Abstract
In this tissue-culture study, some effects of phagocytosis on the cell were investigated. Third-passage bovine trabecular-meshwork cells were incubated with latex microspheres for periods of up to 60 hr. Cells which had been involved in phagocytosis were found to settle at a faster rate than control cells, but if microspheres were added to the medium of recently settled cells, there was a reduction in their proliferative activity. Incorporation of tritiated proline remained unchanged, whereas uptake of tritiated glucosamine increased with the time period of phagocytosis. The fibronectin scaffold was more extensive and elaborate when cells were pre-incubated with microspheres before settlement. Exposure to a low concentration of microspheres promoted a higher uptake of a second presentation of 125I-labelled microspheres--an effect which was not seen if the original dose was too high.

Abstract
The ability of cultured bovine trabecular meshwork cells to phagocytose latex microspheres was studied by electron microscopy. In addition, the incorporation of 125I gamma-globulin-coated microspheres by the meshwork cells was monitored. The cultured cells, on the basis of quantitation by scanning electron microscopy, did not show significant preference between biotic particles (gamma-globulin-coated microspheres) and abiotic particles (uncoated microspheres). Surface microvilli appeared to be involved in the initial stages of phagocytosis; indeed a significant negative correlation was demonstrated between the incidence of microvilli and the commitment to phagocytosis of preconfluent cells. Two weeks postconfluent cells were shown to be significantly less phagocytic than preconfluent cells. The importance of these findings in terms of the behaviour of meshwork cells in vivo is discussed.

Abstract
An ultrastructural, immunohistochemical, and functional study was conducted on cultured bovine meshwork cells. Particular emphasis was placed on the organization of the cytoskeleton, and the cells were viewed either as whole cells or following detergent extraction. For ultrastructural examination, several modes of viewing were adopted, including a detector situated above the specimens collecting secondary electrons (SE), a detector situated beneath the specimen collecting transmitted electrons (STEM), and conventional transmission electron microscopy at 100 KV (TEM). In whole cell mounts, information was obtained about the organization of the cytoskeleton and its relationship to other cytoplasmic organelles. Extraction procedures removed much of the plasma membrane and most organelles. The nucleus and cytoskeleton remained and stress fibers were prominent. Immunohistochemistry showed that the actin content of the cytoskeleton could be preserved after detergent extraction. Detergent-extracted cells decreased their surface area when exposed to MgATP in a dose-dependent manner. The decrease in surface area was associated with disassembly of cytoskeletal stress fibers and was optimal with 1 mM MgATP. Whether or not the change in surface area could be considered a "contractile event" was discussed.

Abstract
Twenty-one soluble proteins, five tRNAs, and three protein-nucleic acid complexes were studied in a systematic manner with regard to their crystallization behavior from polyethylene glycol and ammonium sulfate solutions in the presence of 0 to 1.5% beta-octyl glucoside. Our observations suggest that this neutral detergent does influence in a very positive way the growth characteristics of the macromolecules included in this experiment. In general, more reproducible and rapid growth was noted with an increased number of large individual crystals at the expense of microcrystals. In several cases, new crystal forms were discovered. Selected x-ray diffraction analyses imply that crystals grown in the presence of beta-octyl glucoside diffract as well or better than those grown in its absence. In addition, a screen of two proteins grown in the presence of 14 different common detergents suggested that a general detergent effect may be beneficial for the growth of crystals of biological macromolecules.

Abstract
The major extracellular protein of Penicillium cyclopium has been isolated from its culture media and purified by ammonium sulfate fractionation, gel, and ion-exchange chromatography. We show this secreted protein to be endopeptidase. The molecular weight is approximately 32,000, the pI is 5.0, and the pH optimum using a variety of protein and synthetic substrates is around 7.0. Inhibition studies show that the protease is not inhibited by pepstatin nor by p-chloromercuribenzoic acid, indicating, respectively, that it is not an aspartyl protease nor a thiol protease. Complete inhibition is observed, however, with phenylmethanesulfonyl fluoride. Three crystal forms suitable for high resolution x-ray diffraction studies have been obtained from this purified protease with reflections being observed to well beyond 3.0 A resolution. One form having a needle morphology is of the orthorhombic crystal class and has space group P2(1)2(1)2(1). The unit cell dimensions are a = 41.9 A, b = 43.2 A, and c = 111.5 A with 1 molecule of the protease occurring in the asymmetric unit. The second form grown at pH values less than 6.0 has a plate morphology, is of orthorhombic space group P2(1)2(1)2(1), and has unit cell dimensions a = 59.12 A, b = 62.33 A, and c = 70.62 A. The third form is polyhedral in habit, is also of space group P2(1)2(1)2(1), and appears when the pH of the mother liquor is greater than 7.0. The cell dimensions of this crystal form are a = 57.07 A, b = 58.82 A, c = 70.79 A, and again there is 1 molecule/asymmetric unit. Three-dimensional structural analysis by x-ray diffraction is now underway. All crystal forms are somewhat denser than the norm having mass to volume ratios of 1.58, 2.00, and 1.85 A3/dalton, respectively.

Abstract
1 A comparison of total sulphapyridine saliva concentrations resulting from administration of sulphapyridine and sulphasalazine at equimolar doses has been carried out. It is concluded that the extent of azo reduction of sulphasalazine to release sulphapyridine is complete in healthy volunteers. 2 An ampicillin course of treatment alters the azo reduction of sulphasalazine. The extent of cleavage is reduced by one third on average. There is no change in the rate of absorption of the release sulphapyridine. 3 An ampicillin course of treatment does not alter the disposition of sulphapyridine. The changes noted in acetyl conjugate plasma concentrations are entirely consistent with reduced availability of sulphapyridine.

Abstract
A new cell line, SS78, was established from a primary renal cell carcinoma of a Caucasian male. The tissue was dispersed with collagenase, and viable cells were separated by flotation on a Ficoll-Hypaque gradient. In culture, the SS78 cells retained a distinct epithelial morphology, and no fibroblast like cells were seen. The cultured cells were aneuploid with a modal chromosome number of 80 and had several marker chromosomes. Inoculation of the cultured cells into athymic nude mice caused tumors at the sites of inoculation.

Abstract
A long-term CEA follow-up was evaluated statistically for a series of 74 patients with primary colorectal carcinoma who underwent resections for cure. Thirty-three recurrences and 29 deaths were reported among this population after a median follow-up interval of 55 months. Preoperative CEA levels correlated with the Dukes' classification. However, the preoperative level adds significant information to Dukes' classification in the prediction of recurrence. Postoperative CEA assays taken later in the clinical evaluation process carry the most prognostic information for subsequent recurrence. Using matched-pairs techniques, the authors noted that CEA often rose in anticipation of recurrence, sometimes as early as one year before recurrence. The following four follow-up CEA events were evaluated: 1) three consecutive rising CEA's 2) CEA rises 5.0 ng/ml; 3) CEA exceeds 5.0 ng/ml; 4) CEA exceeds 5.0 ng/ml two consecutive times. The follow-up CEA events examined were characterized by false positive rates ranging from 17% to 66% and true positive rates ranging from 43% to 56% in the prediction of recurrence. From follow-up CEA evaluations, further clinical investigation appeared most warranted when CEA exceeds 5.0 ng/ml at two consecutive follow-up evaluations, but the chances of finding any subsequent recurrent disease was near 50%. Among patients experiencing recurrences, although forewarned by CEA elevations, there was no subsequent time when patients were most likely to have recurrence of disease.

Abstract
Raman spectra of 1,2-dimyristoyl-sn-glycero-3-phosphocholines specifically deuterated in the 2 chain at one of positions 3, 4, 6, 10, 12, and 14 have been obtained as a function of temperature. The frequencies of the CD2 vibrational stretching modes depend on the position of the labeled CD2 group, being maximum at position 3 of the acyl chain and then decreasing until they become constant beyond position 6. This frequency dependence is interpreted in terms of the inductive effect of the charge distribution of the acyl chain carboxyl group. In both gel and liquid-crystal phases, the Raman line widths depend on the position of the CD2 group, being minimum at position 6 and increasing toward both ends of the hydrocarbon chain. The width of the CD stretching bands abruptly increases at the phase transition temperature. The magnitude of the increase depends upon the position of the label, increasing almost linearly up to position 10 and then decreasing for positions 12 and 14. The spectra for the CD2 group at position at position 3 and the terminal CD3 group are almost the same in both phases. These results are interpreted in terms of the effects of hydrocarbon chain organization on the vibrational modes.

Abstract
The values of a number of anthropometric, cardiovascular and biochemical variables have been compared between tribal and non-tribal Samburu. Significant differences between the two groups were found for ponderal index, supra-iliac and mid-calf skinfold thicknesses, pulse rate and both systolic and diastolic blood pressures. Similar analyses were performed on samples from tribal and non-tribal Maasai; here significant differences were found for ponderal index, height, biceps skinfold thickness, pulse rate and systolic blood pressure. No significant differences were found in serum cholesterol or serum triglyceride for either the Samburu or the Maasai. Greater variability of the skinfold measurements was found in the non-tribal Samburu than in the tribal group; this effect was less marked in the Maasai. A principal component analysis and three discriminant function analyses were performed on the Samburu data. These analyses showed that the most marked difference between the tribal and non-tribal groups was in their blood pressure levels, the non-tribal sample having significantly higher mean values than the tribal members. Possible causes for the observed differences between tribal and non-tribal groups are discussed, and the findings are contrasted with those of an earlier study, in which significant differences in cholesterol but not in blood pressure were found between samples of rural and urban Maasai. This leads to the tentative hypothesis that blood pressure is affected immediately by the change in environment, whereas the effect on cholesterol levels is a longer-term one.

Abstract
Three experiments were conducted to investigate the verbal performance of the right cerebral hemisphere in right-handed individuals with normal intact brains. A manual reaction time (RT) measure was used to assess the relative efficiency of lateral stimulus-response pathways (e.g., left visual field-right hemisphere-left hand) in processing linguistic information. Experiment 1 showed that the right and left hemispheres were equally efficient at recognizing concrete object nouns in a lexical decision task. The RT data also suggested that abstract nouns may be recognized only by the left hemisphere. Experiments 2 and 3 demonstrated the right hemisphere's ability to detect semantic relationships between concrete nouns and their superordinate categories. The findings were discussed in terms of their consistency with data from split-brain research and their implications for models of the functional organization of language skills in the normal brain. It was proposed that the right hemisphere in the intact brain can play a functional role in processing language.

Experiments 2 and 3 demonstrated the right hemisphere's ability to detect semantic relationships between concrete nouns and their superordinate categories. The findings were discussed in terms of their consistency with data from split-brain research and their implications for models of the functional organization of language skills in the normal brain. It was proposed that the right hemisphere in the intact brain can play a functional role in processing language.

Abstract
The possible role of pigs as arbovirus maintenance hosts and their importance as amplifier hosts was studied. Blood samples from 464 pigs of all ages collected in 1962 and 1964 were tested against 10 arboviruses. Antibodies to Japanese encephalitis and Getah viruses were particularly prevalent and their calculated monthly infection rates were 19-5% and 13-3% respectively. In 1969, 447 pigs were bled monthly throughout the year and the infection rates for Japanese encephalitis virus were calculated in pigs during the first year of life. Infection rates were not uniform throughout the year; the rate increases as the pig grew older and there was a marked seasonal increase in the infection rate in the period from November to January. This coincided with the seasonal major population peak of Culex tritaeniorhynchus following intense breeding of this mosquito prior to rice planting. It is suggested that, in Sarawak, the pig acts as a maintenance host of Japanese encephalitis in a cycle involving C. gelidus mosquitoes and also acts as an important amplifier host towards the end of the year in a cycle involving C. tritaeniorhynchus. It is further suggested that Getah virus is maintained in a similar cycle between C. tritaeniorhynchus and pigs.

Abstract
Plasma calcitonin, glucagon and parathyroid hormone were measured in patients with acute pancreatitis. Plasma calcitonin was not detectable in 6 specimens obtained from the hypocalcaemic patients. Plasma glucagon values were similar in patients with acute pancreatitis and control subjects and were unrelated to hypocalcaemia, which was not even induced by glucagon infusion. High or rising parathyroid hormone levels were noted in association with hypo-and normocalcaemia, suggesting that parathyroid hormone rises and maintains plasma calcium within normal limits. Plasma parathyroid hormone was, however, undetectable in 8 patients with prolonged hypocalcaemia. Deficiency of parathyroid hormone due to its destruction by proteolytic enzymes or because of parathyroid gland exhaustion is suggested as the major factor inducing persistent hypocalcaemia in acute pancreatitis. Administration of parathyroid hormone should, therefore, be considered in patients with acute pancreatitis when hypocalcaemia does not respond to intravenous calcium therapy.

Abstract
449 human sera collected in a Land Dyak village were tested for antibodies to 11 arboviruses. Japanese encephalitis and dengue virus antibodies were particularly prevalent. The rates of infection with these viruses were estimated to be 5-2% per annum for Japanese encephalitis, 8-8% for dengue 1 and 4-3% for dengue 2. Chikungunya virus antibodies were quite common with an annual infection rate of the order of 5% per annum. Infections with other Group A and B and Bunyamwera group viruses were generally at a low level.

Abstract
Nephrotoxic nephritis induced in rats was employed as an experimental model to investigate the possible effects of rheumatoid factor on in vivo antigen–antibody reactions. Rats injected simultaneously with rheumatoid arthritis serum and rabbit nephrotoxic globulin showed a three-fold increase in immediate proteinuria compared with rats injected with nephrotoxic globulin alone. This potentiating effect of rheumatoid arthritis serum was evident even when the serum was injected 48 hr after the nephrotoxic globulin and was also apparent to a lesser extent in rats decomplemented by a prior injection of aggregated human IgG. Normal human serum had no effect on the proteinuria produced by a standard dose of nephrotoxic globulin while rheumatoid arthritis serum injected with normal rabbit globulin did not increase urinary protein excretion above baseline levels. In rats injected with rheumatoid arthritis serum and nephrotoxic globulin, human IgM (presumably rheumatoid factor) was detected by immunofluorescence on the glomerular basement membrane along with the nephrotoxic globulin and rat complement and persisted at this site for as long as 42 days after the initial injections. Rheumatoid factor activity was also recovered by elution from glomeruli isolated from rat kidneys 24 hr after the injection of rheumatoid arthritis serum and nephrotoxic globulin.
