    Notes: Abstract  To evaluate treatment-related changes of the reticulin stain-measured fibrosis in Ph1+-CML, a clinicopathological study was performed on sequential trephine biopsies of the bone marrow following either interferon (IFN) or busulfan (BU) monotherapy. Using the monoclonal antibody CD61 for the identification of megakaryopoiesis and Gomori's silver impregnation method, number of megakaryocytes and density of argyrophilic (reticulin and collagen) fibers were determined by morphometry. We studied specimens from 26 patients with IFN-alpha 2b (including nine patients with additional IFN gamma) therapy and from 23 patients who had received BU. In both groups, repeated bone marrow biopsies (total 125) revealed a significant increase in the fiber content, as well as in the number of megakaryocytes during treatment. To assess the dynamics of myelofibrosis more precisely, computation of differences in the degree of fiber density between the first and last examination was carried out. Regarding the considerable variations in the biopsy intervals, a so-called myelofibrosis progression index (MPI) was calculated. Following this rationale, we were able to demonstrate that, in comparison to the BU-group, speed of progression of bone marrow fibrosis was significantly increased in CML patients treated with IFN. Preliminary statistical analysis indicated a relationship between myelofibrosis on admission, which was always associated with increased growth of megakaryocytes, and the MPI with survival. Even when these parameters were regarded, prognosis was significantly more favorable in the IFN-treated patients. The failure of IFN and BU to inhibit the evolution of myelofibrosis may be related to several conversely acting pathomechanisms. Among others, the inability of both therapeutic agents to reduce the number of megakaryocytes more effectively should be taken into consideration.

    Notes: Abstract This study examines educational/occupational outcome and social functioning of adolescents treated for psychosis (mean onset age 16.1 yrs±1.3). In a sample of 157 subjects, 26 patients with schizoaffective episodes (defined as any episode meeting ICD-9 criteria for schizoaffective psychosis, occurring at any time during the course of illness) were compared to 101 patients with schizophrenia, and to 30 affective disordered patients, all without schizoaffective episodes. Follow-up information (mean interval 7.3 yrs ±4.3) was obtained on 130 subjects.The three groups did not differ concerning sex, duration of first inpatient treatment, symptoms and social competence at discharge, nor at follow-up. At the time of outcome subjects with schizoaffective episodes showed greater similarities to schizophrenic than to severe affective disorder. Educational and occupational impairment was found in 72% of the schizoaffective group (schizophrenic group 79%, affective group 40%), obvious or more severe social disability in 86% of the schizoaffective group (schizophrenic 79%, affective 40%). Disabilities regarding performance of specific social roles and specific downward educational and occupational drifts were found to be more marked in schizoaffective than in affective disorder. Implications for further research and clinical practice are discussed.

    Pelvic ultrasound scanning of the ovaries in adolescent anorectic patients at low weight and after weight recovery (1997)

    Notes: Abstract In sixteen adolescent anorectic inpatients with secondary amenorrhea pelvic ultrasound examination of the ovaries was performed at lowest weight and after weight recovery. The outcome was assessed six months later at follow-up, assigning the patients to the categories of good, intermediate and poor outcome according to the modified Morgan and Russell criteria. At lowest weight all patients’ ovaries were smaller than expected for age. After weight recovery the good outcome group had mature and fully developed ovaries whereas the ovarian morphology of patients with poor outcome remained prepubertal. The ovarian volume in the good outcome group was significantly higher than in the poor outcome group. From a threshold BMI of 17.8 upwards we observed a positive linear correlation between BMI and ovarian volume. At BMI 18 the probability for recovered ovaries was 53% rising to 82% at BMI 19.8, which was the highest noting in our study. Nevertheless, we could not find a clear cut-off BMI for definite prediction of recovered ovaries. Therefore, in patients with anorexia nervosa pelvic ultrasound is a very suitable method for determining the target weight required for recovery of ovarian function and resumption of menses. Normalized ovaries indicate favourable outcome and physical recovery.

    Notes: Liquid Crystals with Aliphatic Groups between Cyclohexane Rings - Synthesis of 1,4-Bis(4-n-alkylcyclohexyl)butanes and Esters of 4-[4-(4-n-Alkylcyclohexyl)-butyl]cyclohexanolsThe synthesis of 1,4-bis-(4-n-alkylcyclohexyl) butanes (1), esters of 4-[-(4-n-alkylcyclohexyl)butyl]cyclohexanols (2) and some analogous aromatic compounds are described. The thermal stability of mesophases of these compounds are in the order of the analogous ethylene-bridged liquid crystals. The reason for this result seems to be the combination of molecular rigidity and conformational flexibility.

    Notes: Photochemistry and Photophysics of 3-(2-Isoxazolinyl)-phenylketones3-Benzoyl-Δ2-1,2-oxazolines (1-6) are formed by 1,3-dipolar cycloaddition between benzoylnitril-N-oxide (8) and dihydrofurane 9 or 1,3-dioxep-5-enes (10a-c). The preparative yields are small due to the competitive dimerization of the dipole 8. Two stereoisomers are obtained by using 2-substituted 1,3-dioxep-5-enes as dipolarophiles. The different steric position of the substituents in 3-6 gives rise to different spectral data. The synthesized ketones possess triplet states with a high degree of charge transfer character. Therefore, the ability to H-abstraction reaction from alcohols is small. For ketone 2 and methanol as H-donor a rate constant of kHMeOH = 4,1 · 102 M-1s-1 is determined. Also by electron transfer reactions with triethylamine and some onium compounds the reactivity of the T1 of the ketones 1-6 is less compared to those of nπ* excited ketones. The photolysis of the ketones takes place very unselectively and leads to a product mixture. The quantum yields for the decay of the ketones are 10-2 to 10-3.
