In normal rabbits and mice, one i.v. injection of scarlet fever toxin (ET) (30 000 STD per kg of rabbit weight or 20-g mouse) elicited a similar biphasic change in carbon clearance rate - early depression followed by a stimulating phase - as has been described for Gram-negative endotoxins. Prolonged depression without a subsequent stimulation phase was obtained in mice by raising the ET dose. The reasons of the discrepancy between these findings and those of Hanna and Watson (1965b) are discussed. Pyrogenic tolerance to ET is not accompanied by accelerated carbon clearance and is not impaired by RES blockade. A possible mechanism of ET tolerance is suggested.

Reports on neuropsychological assessment and psychopathological symptoms in HIV-1 patients are rather different. The aim of the study was to assess frequency and extent of noopsychic changes and psychopathological symptoms in HIV-1 patients of different risk groups. Of the 77 patients being included in the study 35 patients belonged to risk group 1, 42 to risk group 2. The patient groups were compared to a control-group of healthy volunteers (n = 50) and to a control-group of HIV-negative i.v. drug-addicts (n = 31). The psychometric test battery included Raven and MWT Test, Benton Test, numerical memory Test, ARG Test. Personality variables were assessed by MMPI, Psychopathology by AMDP-System, Hamilton Depression Scale, Wellbeing Scale (von Zerssen), STAI 1 and 2 and BPRS. Patients of risk group 1 showed significantly less impairment of noopsychic performance than patients of risk group 2. Risk group 1 showed only in the Benton Test significant impairment compared to healthy volunteers while risk group 2 in most of the tests was impaired. Risk group 2 did not show impairment compared to the control-group of seronegative drug users. Depressive syndromes mainly in risk group 2 showed a significant influence on the noopsychic performance.

Although the availability of antibiotics has reduced the general incidence of donovanosis, the disease remains prevalent in India, Papua New Guinea, parts of southern Africa, and the West Indies. Clinical variants of this sexually transmitted disease include ulcerogranulomatous, hyertrophic, necrotic, and cicatrical. Described here is the case of a 20-year-old Zulu female who developed donovanosis with hypertrophic and ulcerogranulomatous lesions during the third trimester of pregnancy. When the patient presented at 36 weeks, she reported a 10-week history of vaginal ulceration and a 6-week history of swelling in the inguinal region. The ulcerative lesion, located at the introitus, had raised edges 2 cm in diameter, while the dry keloidal-like lesion 2 x 4 cm was present in the inguinal region. This is the first reported case of a combination of two variants of donovanosis in one individual. Histologic examination revealed mildly acanthotic surface squamous epithelium with underlying granulation tissue containing plasma cells, lymphocytes, pockets of neutrophils, and scattered histiocytic cells. Donovan bodies with the typical safety pin appearance were demonstrated by a Giemsa stained tissue smear. Treatment with 500 mg of erythromycin twice daily for 2 weeks resolved the disease. Both the incidence and severity of donovanosis appear to increase during late pregnancy, presumably because of depression of lymphocyte proliferative responses.

We have examined the sites phosphorylated on acetyl-CoA carboxylase by three protein kinases which have been shown to inactivate the enzyme, i.e. cyclic-AMP-dependent protein kinase, acetyl-CoA carboxylase kinase-2 (ACK2, purified from rat mammary gland) and the AMP-activated protein kinase (formerly called acetyl-CoA carboxylase kinase-3, purified from rat liver). Each protein kinase phosphorylates two out of three sites (termed 1-3) which have been established by amino acid sequencing. The two sites phosphorylated by each kinase can be recovered on separate peptides, TC1 and TC2, derived by combined digestion of the native enzyme by trypsin and chymotrypsin: TC1 = Ser-2Ser(P)-Met-3Ser(P)-Gly-Leu; TC2 = Arg-Met-1Ser(P)-Phe- Cyclic-AMP-dependent protein kinase phosphorylates sites 1 and 2 exclusively, whereas the AMP-activated protein kinase phosphorylates sites 1 and 3, plus at least one other minor site. ACK2 phosphorylates site 1 and, more slowly, an unidentified site(s) within TC1. We have also established the structures of the single major phosphopeptides (T1 and C1 respectively) which are recovered by HPLC after acetyl-CoA carboxylase phosphorylated by cyclic-AMP-dependent protein kinase is digested with trypsin or chymotrypsin alone. T1 is related to TC1, and has the structure: Ser-Ser(P)-Met-Ser-Gly-Leu-His-Leu-Val-Lys. C1 is identical with TC2. We have carried out studies on the correlation of the activity of acetyl-CoA carboxylase with the occupancy of sites 1, 2 and 3 during phosphorylation by each of the three protein kinases. The results suggest that phosphorylation of site 3 is primarily responsible for the large decrease in Vmax produced by the AMP-activated protein kinase, while phosphorylation of site 1 may be primarily responsible for the increase in A0.5 for citrate and more modest depression of Vmax produced by cyclic-AMP-dependent protein kinase and ACK2. Our results emphasize that amino acid sequence information is essential in the unequivocal interpretation of data from phosphopeptide mapping experiments and allow a more complete interpretation of previous data on phosphorylation of acetyl-CoA carboxylase in intact cells. They also open the way to experiments which could establish the physiological roles of these protein kinases in the control of fatty acid synthesis.

Intratracheal inoculation of 2-week-old quail chicks with Aspergillus fumigatus resulted in the development of clinical signs within 24 h of infection. These were characterized by anorexia, depression, accelerated respiration and gasping followed by death. The acute course of the disease lasted for 7-10 days followed by recovery in the surviving chicks. The overall mortality during a 6-week observation period was 20%. Although the mean body weight of A. fumigatus infected quail chicks continued to be slightly lower throughout the experiment but the difference, in comparison to controls, was not significant except at 42 days post-infection. There was no appreciable difference in the mean values of Hb, TEC, PCV, MCV, MCH and MCHC between the infected and control chicks at any stage of infection but TLC revealed a leucocytosis from 2-7 days which was the result of increase in the relative percentage of heterophils and decrease in lymphocytes.

A longitudinal design was employed to test the main and stress-moderating effects of young adolescents' perceived family environment (Family Environment Scales; FES; Moos & Moos, 1981) on their depression, anxiety, and self-esteem. This study was part of a larger longitudinal project (L. Cohen, Burt, & Bjorck, 1987) that demonstrated the significant cross-sectional effects of the young adolescents' controllable and uncontrollable negative events, and the significant longitudinal effects of the former. The present cross-sectional analyses demonstrated the hypothesized main effects of the FES scores; families perceived as cohesive, organized, and expressive were related to positive psychological functioning, whereas families perceived as conflict-ridden and controlling were related to negative functioning. However, in general these effects were nonsignificant in the longitudinal analyses. Although there were a number of significant Negative Events x FES interactions, in no instance did the pattern support the hypothesized stress-buffering role of positive family climate.

The present study was planned to investigate whether the sum of ST segment depression in 12-lead electrocardiogram (sigma STD) in relation to change in heart rate (delta HR) during exercise, sigma STD/delta HR index, could be utilized to predict the extent of underlying coronary artery disease. Two hundred and twenty-six consecutive patients were included in this study, 191 men and 35 women, aged 28-74 years (mean 56). Patients were classified into two groups. Group I consisted of 165 patients with either no coronary disease, single or double vessel disease. Group II included 61 patients with triple vessel or left main stem stenosis. It was found that the sigma STD/delta HR index at 25 mm. beat-1 X min. 10(2) provided the best separation between Groups I and II patients. All but 3 of the 61 patients in Group II had a sigma STD/delta HR index greater than 25. In contrast, all but 4 of the 165 patients in Group I had an index less than 25. The sensitivity, specificity and positive predictive value in the identification of Group II patients by using the index were 95%, 98% and 94% respectively. Utilization of ST segment depression of greater than or equal to 2 mm in a VF alone as a test criterion for the recognition of Group II patients had a low sensitivity (41%), specificity (88%) and positive predictive value (56%).(ABSTRACT TRUNCATED AT 250 WORDS)

Ionizing radiation inhibited the development of specific haemolysin-producing cells (PFC) and depressed the incorporation of (3H) thymidine by rabbit spleen explants responding to SRC in the culture medium. In contrast to these effects, the rates of incorporation of precursors for protein and RNA synthesis were much less affected. The depression of (3H) thymidine incorporation was found to result from a quantitative reduction of new DNA synthesis, without any change in the proportion of labelled cells, at any time after irradiation. The DNA synthesis occurring in these cells preparing to develop antibody-producing capacity was thus radio-sensitive, but the exact nature of the defect resulting from exposure to radiation requires further study.

Serum amino acid (AA) levels were determined for 18 cholecystectomy patients who had preserved and immediately utilized G-I function for absorption of 3,000 kcal/day elemental diet. Ten were given 132 gm AA/day; eight were given only 66 gm AA/day. Historical controls were 27 comparable patients who had received conventional hypocaloric intravenous (IV) regimens. Unfed patients' branched chain AAs (BCAAs) + TYR were depressed initially, then rebounded by day 3 or 4. Their glucogenic AAs were still depressed after 72 hours. Complete restoration of the basal pattern required five to ten days. Fully nourished patients maintained basal levels of all AAs on day 1. Every AA rose above basal, some with statistical significance as early as day 2. Moderately fed patients had BCAA depression, but for only 24 hours. LEU, ILE, VAL, TYR, MET, ASP, LYS, and ARG had already returned to basal levels on day 2, while the remaining AAs were much less depressed than in the unfed controls. All fed patients were discharged uneventfully 24-48 hours postcholecystectomy. The positive protein balance and elevated AA levels correlate with enhanced wound healing, host sepsis resistance, and shortened hospitalization.

Twenty HIV positive and 68 HIV negative subjects were assessed by the Hospital Anxiety and Depression Scale and by the Alcohol and Drugs Frequency Schedule immediately prior to notification of their HIV serostatus and 6 months after serodiagnosis. The 2 groups did not differ significantly in levels of anxiety or depression at baseline or follow-up. There were borderline levels of pathological anxiety prior to notification of HIV serostatus in both groups. The drop to normal levels of anxiety which had occurred by follow-up was significant in the HIV positive group. About a third of subjects in both groups were regularly making use of alcohol and/or drugs, both at baseline and follow-up. Mean levels of weekly alcohol intake for both groups ranged from about 20 to 30 units per week. The drugs most commonly used (in any frequency) were nitrates ('poppers') and cannabis.
