    Notes: Abstract This paper presents the results of a study carried on an urban population in Belgrade investigating the connections between relapse in schizophrenia and the expressed emotion (EE) status of families where at least one of the patient's parents was a member of the household. The overall rate of high EE was just under 50%, in the middle of the range of values reported in studies carried out elsewhere. Relapse was found to be 10 times more frequent in patients whose families were rated high in EE. The sample consisted of 30 patients with hebephrenic schizophrenia and 30 with paranoid schizophrenia. The results suggested that these subtypes may be associated with different attributes of EE. Criticism was more frequent in families of patients with paranoid schizophrenia, while emotional overinvolvement was more frequent in families having a hebephrenic offspring. The different components of EE, suitably combined, may differentiate between the two subtypes of schizophrenia in terms of relapse rate. The relative odds for high criticism were similar for both subtypes, but for maternal overinvolvement (EOI) the odds were 10.5 for hebephrenic as against 2.3 for paranoid schizophrenia. Thus, EOI was more common in the families of those with hebephrenia and also led more frequently to relapse. There was also an inverse relationship between relapse rate and warmth, whether paternal or maternal. This was significant in both subtypes, and indicated that the threshold for the positive effeet of warmth was higher for fathers than for mothers. Marital conflict was significantly related to relapse, mainly because it was associated with high EE. Within the high EE group marital conflict did not predict relapse, whereas it was predictive in the low EE group. This implies that it was a source of some stress, but the effect was minor in comparison with that of high EE, emerging only in a low EE environment. Patient aggression showed only a non-significant trent towards association with relapse and with EE.

    Notes: Abstract The development of chronic inflammatory periodontal diseases is strongly correlated with the growth and maturation of subgingival bacterial colonies. Consequently a major preventive goal should be the control of plaque formation. We conducted a randomized, controlled trial to examine the short-term effect of an intensive instructional program without professional prophylaxis on the gingival health of 240. 11-14 year old school children. Plaque index (P1I), gingival index (GI), bleeding index (BI) and probing pocket depth (PD) were examined 4 × by 1 examiner blinded to the instruction. During the period of instruction, subjects in the experimental groups were involved in a plaque and gingivitis prevention program provided in separate educational sessions. One of the experimental groups (E-l: n=80) was provided with a new toothbrush, toothpaste and instruction while the second experimental group (E-2: n=80) was provided with toothbrush, toothpaste, dental floss and instruction. In the control group (C; n=80) only dental examinations were provided: no preventive program or oral health measures were conducted. Examinations were conducted every 3 months during the instructional period and at 6 months following the completion of the active preventive programme. During the experimental period there was a significant decrease (p〈0.001) in the mean P1I. GI and BI of the experimental groups following the program while in controls there was a slight but not significant increase of mean values (p 〉 0.05). During the preventive program experimental groups exhibited small but not significant (p 〉 0.05) reductions of PD. Experimental group 1 showed similar PH. GI. BI and PD scores as experimental group 2 during the study. After the instructional program was completed and a period of 6 months had passed, there was a large and significant (p 〈 0.001) increase of mean P1I. GI and BI scores in both experimental groups back to the baseline levels. We conclude that a short-term preventative program without professional instrumentation induces a transient improvement of gingival health of schoolchildren but only during the instructional period. The maintenance of improved gingival health over longer time periods requires prolonged, repeated instruction by professionals. These measures may be difficult to institute and are of questionable cost-effectivness.

    Notes: Abstract Filter-sterile culture filtrates of isolates of Diaporthe phaseolorum var. caulivora, Diaporthe phaseolorum var. sojae (anamorph Phomopsis sojae), and Phomopsis longicolla, causal agents of stem canker, pod and stem blight, and seed decay, respectively, on soybeans (Glycine max), grown on Czapek-Dox broth inhibited germination of soybean seeds (significant at P=0.05). Wilting and necrosis of excised soybean seedlings was significantly greater than the controls when treated with culture filtrates of P. longicolla and P. sojae. Soybean seedling radicle growth inhibited significantly when culture filtrates of P. longicolla were added.
