Abstract
The enzymatic activity of salivary amylase bound to the surface of several species of oral streptococci was determined by the production of acid from starch and by the degradation of maltotetraose to glucose in a coupled, spectrophotometric assay. Most strains able to bind amylase exhibited functional enzyme on their surface and produced acid from the products of amylolytic degradation. These strains were unable to utilise starch in the absence of salivary amylase. Two strains failed to produce acid from starch, despite the presence of functional salivary amylase, because they could not utilise maltose. Strains that could not bind salivary amylase failed to produce acid from starch. In no case was all the bound salivary amylase active, and two strains of Streptococcus mitis which bound amylase did not exhibit any enzyme activity on their cell surface. The ability to bind amylase may confer a survival advantage on oral bacteria which inhabit hosts that consume diets containing starch.

Abstract
The chemical composition, subpopulation distribution and peak hydrated density of high-density lipoprotein (HDL) were examined in 18 morbidly obese women with either normal glucose tolerance or with non-insulin-dependent diabetes mellitus (NIDDM), and in 15 age-matched lean control subjects. Similar measurements were made in the morbidly obese subjects after gastric bypass surgery for weight loss. In the diabetic group, HDL was relatively protein-enriched and cholesterol- and cholesterol ester-poor compared with the lean controls. The same trend was seen in the nondiabetic group, although the cholesterol ester difference was not significant. In both cases, both electrophoretic and density gradient analysis showed that plasma HDL contained more of the HDL3 and less of the HDL2 subfractions than that for the lean controls. Following surgery in the diabetic group, the protein percentage of HDL decreased, and that of cholesterol ester increased; for the nondiabetic group, the protein decreased and phospholipid increased. In the diabetic group, a shift of the electrophoretic HDL subpopulation distribution toward more HDL2 accompanied these changes. Average hydrated peak density of HDL shifted from the HDL3 to the HDL2 range for the diabetic group following surgery; for the nondiabetic group the peak density also decreased but still remained within the HDL3 range. In all cases, the differences seen were more pronounced among the diabetic patients. These changes in the properties of HDL after gastric bypass surgery may favorably influence the risk for coronary heart disease usually associated with diabetes.

Abstract
The possible causes of the enhanced risk for coronary heart disease (CHD) were examined in morbidly obese women with normoglycemia, impaired glucose tolerance (IGT), and non-insulin-dependent diabetes mellitus (NIDDM) before and after gastric bypass surgery. Compared with age-matched lean women, plasma lipid and apolipoprotein concentrations of the obese women before surgery favored atherogenesis. The risk for CHD may further be exacerbated in the IGT and NIDDM groups by the prevalence of smaller and denser low-density-lipoprotein (LDL) particles. LDL size correlated negatively with plasma insulin levels independent of triglyceride levels, age, or body mass index (BMI). After surgery, BMI, plasma insulin, and triglyceride levels decreased, but LDL size increased, and LDL density decreased. Neither cholesterol nor LDL cholesterol levels were affected after surgery, but high-density-lipoprotein cholesterol was increased in all patients after surgery. Although the mechanisms underlying the changes in the properties of LDL could not be determined from this study, these changes appear to be of benefit in reducing CHD risk in these patients.

Abstract
Currently it is standard practice in many acute care hospitals to use only sterile water in humidifier reservoirs for the delivery of low-flow oxygen therapy. This practice is based primarily on the Centers for Disease Control's 1982 "Guideline for the Prevention of Nosocomial Pneumonia." The present study was designed to investigate and compare the bacterial contamination of tap water and sterile water used to fill clean (nonsterile) disposable oxygen humidifier reservoirs. Disposable oxygen humidification reservoirs were assembled weekly according to standard protocol and regulated to deliver oxygen, 4 to 6 L/min, continuously for 5 consecutive days. Each of 48 reservoirs was filled with either tap water (24) or sterile water (24) and cultured daily. All disposable equipment was discarded after the final culture on the fifth day. An aliquot of water was obtained daily from each reservoir and plated to trypticase soy agar pour plates and to a matched trypticase soy broth. Bacterial growth was observed on trypticase soy agar pour plates from 54 (45.0%) of 120 sterile water reservoir cultures and from 38 (31.7%) of 120 tap water reservoir cultures (p greater than 0.05). Bacterial growth from the matched trypticase soy broth cultures was observed only from two sterile water reservoirs. The microorganisms identified from the sterile water reservoirs included Enterobacter agglomerans and Serratia and Bacillus spp. The use of tap water for low-flow oxygen humidification was determined to be safe at our hospital by the infection control committee. This procedural change contributed approximately $6000 to the cost reduction efforts of the respiratory therapy department.

Abstract
Fetal and neonatal calcium requirements impose heavy demands on maternal bone and mineral homeostasis. The functional response of maternal osteoblasts to this stress is poorly understood. Therefore, plasma osteocalcin (OC) levels were measured by homologous RIA in age-matched nonpregnant, pregnant, and postpartum ewes to evaluate osteoblast function. In pregnant ewes from day 35 of gestation to term, the plasma OC level was suppressed to 8.2 +/- 0.5 micrograms/liter (mean +/- SEM; n = 36) compared with age-matched nonpregnant ewes (18.3 +/- 1.1 micrograms/liter; n = 39; P less than 0.0005). Plasma OC rose to the nonpregnant value by day 20 postpartum and was elevated above this level for the following 40 days (e.g. 44.0 +/- 5.0 micrograms/liter at 48-53 days; P less than 0.0005). The timing of changes in plasma OC levels and weaning did not correlate. The validity of plasma OC measurement as a marker of osteoblast function was assessed by determining the OC plasma production and clearance rates using an [125I]ovine OC infusion method. The OC plasma production rates in matched controls (n = 6), pregnant (n = 9), and 48-53-day postpartum sheep (n = 7) were 1.5 +/- 0.2, 0.5 +/- 0.04 (P less than 0.001 vs. control), and 3.6 +/- 0.6 mg/day (P less than 0.005 vs. pregnant sheep), respectively. In one ewe studied longitudinally, the OC plasma production rate increased by 15 days after parturition and achieved a 10-fold elevation at 49 days postpartum. The OC plasma clearance rate (3.3 +/- 0.3 liters/h) was the same in control, pregnant, and postpartum ewes. It is concluded that 1) changes in plasma OC levels during and after ovine pregnancy reflected changes in OC production, 2) plasma OC measurements are likely to be a useful index of osteoblast function in pregnancy, and 3) osteoblast function appears to be depressed during ovine pregnancy and enhanced markedly in the interval 20-60 days postpartum. The relationship between osteoblast function, as indicated by OC production, and bone formation remains to be clarified.

Abstract
Two patients with ulcerative colitis developed progressive obstructive pulmonary disease. In one, the abnormality was a sclerosing peribronchiolitis confined to small airways, while the other demonstrated a large airway fibrotic obliterative bronchitis. A review of airway involvement in ulcerative colitis and a discussion of the possible similarity to another extraintestinal manifestation of ulcerative colitis, sclerosing cholangitis, are presented.

Abstract
We have recently reported that a polypeptide mitogen, the embryonal carcinoma-derived growth factor (ECDGF), induces phosphorylation of the epidermal growth factor (EGF) receptor in intact C3H 10T 1/2 mouse fibroblasts with concomittant loss of high affinity EGF binding sites. This phenomenon appears to be mediated through an activation of protein kinase C. Several groups have described an acidic 80,000 dalton protein substrate of protein kinase C. In this paper, we demonstrate that the addition of ECDGF or the phorbol ester TPA to intact C3H 10T 1/2 cells results in the enhanced phosphorylation of this 80 kd protein in vivo. Furthermore, this response is demonstrable in vitro. Thus the addition of ECDGF, the phorbol ester TPA, protein kinase C or phosphoinositidase C to crude membranes prepared from C3H 10T 1/2 cells resulted in the enhanced phosphorylation of this protein. Data obtained by phosphopeptide mapping of the 80 kd protein show that the ECDGF-induced activation of protein kinase C in our membrane preparations is comparable with that obtained in vivo. The availability of an in vitro system in which this response is preserved should now allow a detailed biochemical analysis of the steps between binding of a mitogen to its receptor and the activation of protein kinase C.

Abstract
An unselected consecutive series of 826 patients admitted for acute upper gastrointestinal bleeding underwent urgent endoscopy. Peptic ulcers were found in 402 (49%). Of the 329 ulcer craters that could be fully examined, visible vessels were identified in 156 (47%), other stigmata of recent hemorrhage in 66, and no stigmata of recent hemorrhage in 107. One hundred twenty-nine patients with stigmata of recent hemorrhage (93 of whom had visible vessels) randomly allocated to no endoscopic treatment were observed for evidence of further bleeding. Fifty-four of the 93 patients (58%) with visible vessels rebled, compared with 2 of 36 (6%) with other stigmata of recent hemorrhage. No patient without stigmata of recent hemorrhage rebled. Twenty-seven patients in whom a visible vessel in a gastric ulcer was identified at endoscopy underwent urgent partial gastrectomy because of recurrent bleeding. The vessel identified at endoscopy was found in 26 of 27 resection specimens (96%). The arterial vessel wall protruded above the surface of the ulcer crater in 10 specimens, and clot in continuity with a breach in the vessel wall protruded in a further 10 specimens. Postoperative angiography, when technically possible, showed that the breached artery ran across the base of the ulcer in all of these specimens. Pathological changes were common in the bleeding artery and included arteritis in 24 of 29 (83%) eroded arteries found in these specimens, with aneurysmal dilatation in 14 of 27 (52%) bleeding points that could be fully examined. The ulcer had penetrated to serosa in 13 specimens (45%). The bleeding artery had a mean external diameter of 0.7 mm with a range of 0.1-1.8 mm. This study provides new information about the nature of the bleeding vessel in gastric ulcers, and some of this information is relevant in planning studies of endoscopic therapy for bleeding peptic ulcers. It validates the endoscopic identification of a visible vessel, and confirms that such identification has a high predictive value for the development of recurrent hemorrhage.

Abstract
To determine whether vascular resistance was altered in diabetes, the vascular resistance in both the peripheral arterial bed and the circumflex coronary artery was compared in six normal and five diabetic adult sheep, under pentobarbitone anaesthesia. Diabetes induced by alloxan significantly increased blood glucose (15.6 mmol/l, s.e.m. = 2.8, vs 5.5 mmol/l, s.e.m. = 0.6; P greater than 0.001) compared with controls. Systolic blood pressure was lower in diabetics (92 mmHg, s.e.m. = 12, vs 123 mmHg, s.e.m. = 5; P less than 0.025) as was diastolic blood pressure (73 mmHg, s.e.m. = 15, vs 104 mmHg, s.e.m. = 4; P greater than 0.05). Basal peripheral resistance was lower in diabetics than controls (36.0 mmHg.min/l, s.e.m. = 7.9, vs 42.3 mmHg.min/l, s.e.m. = 2.8), but not significantly so. Methoxamine markedly increased peripheral vascular resistance in both groups, but did not change coronary vascular resistance, due to autoregulation. The dose-response curves of peripheral or coronary arteries to methoxamine showed no significant difference between diabetic and control sheep. Dose-response curves for isoprenaline and noradrenaline infusion suggested there may be altered beta-receptor sensitivity in diabetes. In conclusion, there are marked differences in the vascular beds of diabetic and normal sheep under basal conditions. In contrast to previous studies, alpha-adrenoceptors are not different in diabetics, but further studies in unanaesthetized animals are indicated, as beta-receptor sensitivity may be altered in diabetes.

Abstract
The myelin-associated glycoprotein (MAG) and other myelin proteins were quantitated in homogenates of whole sciatic nerve from adult and 20-day-old Trember mice. In the nerves of adult mice, the concentration of MAG was increased from 1.1 ng/micrograms of total protein in the controls to 1.4 ng/micrograms protein in the Tremblers. By contrast, the concentrations of P0 glycoprotein and myelin basic proteins were reduced to 27% and 20% of control levels, respectively. Immunoblots demonstrated that P2 was also greatly reduced in the Trembler nerves. The specific activity of 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) was 65% of the control level. Immunoblot analysis showed that MAG had a higher than normal apparent Mr in the sciatic nerves of the Trembler mice, but its apparent Mr was normal in the brains of these mutants. In 20-day-old Tremblers, the P0 and myelin basic protein were reduced slightly less to about 40% of the level in the nerves of age-matched controls. CNP and MAG levels were not significantly different from those in controls, and MAG exhibited a shift toward higher apparent Mr similar to that in the adults. The maintenance of high MAG levels despite the severe deficit of myelin, as reflected by the decrease of the major myelin proteins, is consistent with the immunocytochemical localization of MAG in periaxonal Schwann cell membranes, Schmidt-Lantermann incisures, lateral loops, and the outer mesaxon and its absence from compact myelin. The abnormal form of MAG in the peripheral nervous system (PNS) of the Trembler mice may contribute to the pathology in this mutant.

Abstract
The insulin-receptor binding activity and insulin-stimulated growth response of PC13 clone 5 cells were investigated for both the embryo carcinoma (EC) and retinoic acid-induced differentiated derivatives of this cell line. Whereas the EC cell was found to have very few, if any, receptors and showed no demonstrable dependence on insulin for growth, the differentiated derivative cell expressed a large number of insulin receptors and, when challenged with the hormone, showed stimulation of both DNA synthesis and cell division. The same data were obtained for five independent PC13 clones. These results, coupled with previous observations, lend weight to the suggestion that the appearance of specific receptors for growth regulatory substances may be a manifestation of a general change in growth-regulatory mechanisms accompanying EC cell differentiation and loss of malignancy.

Abstract
To assess the effects of radiotherapy on immune status, a wide range of assessments have been performed on patients with localized carcinoma of the cervix uteri undergoing and initially responding clinically to radical pelvic radiotherapy. Neutrophil function was essentially unchanged by treatment. Absolute neutrophil and lymphocyte counts fell after treatment and remained depressed 3 and 12 months following treatment. The proportions of T and B cells dropped with treatment but recovered to near-presentation levels during the follow-up period even though absolute counts remained depressed. In vitro tests of cellular immunity were depressed by treatment and remained so 3 and 12 months following treatment whereas skin test responses remained normal throughout the assessments. Inhibitory plasma effects were observed in phytohaemagglutinin lymphocyte transformation studies on 4 untreated patients; at follow-up these effects were not evident. A variable response in immune indices has therefore been observed in patients in remission after treatment of localized carcinoma cervix stressing the importance of assessing several aspects of immune function and implying that persistent depression of certain indices does not adversely affect the host tumor response. In two patients relapsing after apparently good initial response all aspects of immunological assessment (except serum immunoglobulin levels and neutrophil function) deteriorated.

Abstract
A scheme for dealing with cases of non-accidental injury in children in the Derby clinical area has been operating since 1971. A stable team of doctors, policemen, and social workers deal with each case. The parents are told at once that battering is suspected, and the police and social services department co-operate closely in establishing the facts, supporting the family, and protecting the child. A psychiatric assessment of the parents may help social workers decide on the long-term care of the child, and the forensic physician is invaluable if the case has to go to court. The team has made three recommendations about prevention and management of these cases: a specialist social service team should be set up to deal with these children and regain the skills and knowledge lost when children's departments were abolished in 1971; babies should be routinely weighed naked in infant welfare clinics; and juvenile courts should be able to order a psychiatric report on the parents in care proceedings.

Abstract
1. The fatty acid composition of the cholesterol esters, triglycerides and lecithin components of the major plasma lipoprotein classes was determined before and after the intravenous infusion of a linoleate preparation into a patient with essential fatty acid deficiency.
2. Marked differences developed between the fatty acid composition of the cholesterol esters of very-low-density lipoprotein (VLDL) on the one hand and of low- and high-density lipoproteins (LDL and HDL) on the other hand.
3. The data suggest that the infused linoleate was selectively incorporated into LDL and HDL cholesterol esters by the action of plasma lecithin-cholesterol acyltransferase, after prior incorporation into lipoprotein lecithin. In contrast, there was no rise in the linoleate content of VLDL cholesterol esters, which probably originated in either the liver or the small intestine.
4. These findings support the concept that plasma cholesterol esters are heterogeneous.

Abstract
Deep vein thrombosis was found at postmortem in patients treated by bed rest for myocardial infarction. We were asked to include deep calf massage to our programmed treatments of such patients in an attempt to prevent thromboses. On discussion, our Electrotherapy Department suggested that faradism under pressure might be more effective than deep calf massage. We were aware that many authorities in electrotherapy considered that cardiac disease is a contraindication to faradism under pressure as it is said to increase venous return.
