Ultradian and circadian changes in the cAMP concentration in the preoptic region of the rat.

The concentration of adenosine 3',5'-cyclic monophosphate was measured, during the wake-sleep cycle, in the preoptic region and the cerebral cortex of rats kept in normal laboratory conditions (ambient temperature 22 +/- 0.5 degrees C, 12 h:12 h light-dark cycle) and, during wakefulness, in the preoptic region of rats exposed to extended light and dark periods (i.e. dark in the light hours of the normal photoperiod, and light in the dark hours of the normal photoperiod). The results show that the concentration of cAMP in the preoptic region changes according to the ultradian wake-sleep cyclic, decreasing from wakefulness, through synchronized sleep and to desynchronized sleep. This pattern of change was found to occur both in light and dark hours, however, in the dark hours the levels of preoptic cAMP are higher than those observed in the light hours. In contrast, no significant modification in cAMP concentration was found in the cerebral cortex. In the extended light and dark periods preoptic cAMP concentration increases above the levels found during wakefulness in normal photoperiods. These results show that preoptic cAMP concentration is influenced by ultradian and circadian factors which also appear to be related to sleep processes.

[Salvaging a mass grave from 1945--Lieberose Labor Camp of the Sachsenhausen concentration camp].

It is reported about a recovering a common grave of 577 skeletons from 1945. Investigations of the age of the victims, the cause of death etc. were carried out. There were gunshot fractures at 541 skeletons. In 93.7% out of all cases there were gunshot fractures of the skull and the cervical vertebra. Difficulties arose from root interpretations in addition to intertwinings owing to the location of the skeletons. Indications to belonging to nationality of the victims are discussed by means the results from AB0-analysis and denture works.

[Individual reaction to stress with former concentration camp immates (author's transl)].

The individual disposition to react to different stressors to play an important role in an extreme stress situation, i.e. the incarceration in concentration camps. Ten to fourteen years after their liberation, 219 former concentration camp inmates now living in Bavaria, New York and Israel were given semi-structured interviews. Since no statistically significant correlations between psychic and somatic complaints and incarceration could be found, we computed a factor analysis on illness dimensions. We found high correlations between these and the stress induced by concentration camp incarceration. An important answer to the above mentioned questions was the fact that there was no homogeneous reaction syndrome, such as it has always been described in the literature on concentration camp syndromes. We found four patterns of delayed reaction to stress. According to the contribution of somatic and psychic complaints, the factors were named as follows: 1. psycho-physical syndrome, 2. internal disease, 3. gynaecological illness, 4. psychic (social) syndrome. Personality factors played an important role in the development of these syndromes, because they modified the degree of stress endured. Personality factors were shown to be dependent on life history. The importance of these results for mastering stressors is being discussed.

Coping with illness by a concentration camp survivor.

A 54-year-old concentration camp survivor was observed during her third medical hospitalization in the past 3 months. The meaning of her illness leads to a symbolic reexperience of her traumatic past. Typical features of the Survivor Syndrome are reviewed and compared with the patient's symptoms. Coping mechanisms and management are discussed.

Opposite regulation of cAMP concentration in the quail oviduct and the mouse uterus by tamoxifen. Correlation with estrogen-antagonist and estrogen-agonist activity.

The ability of estradiol and tamoxifen to regulate cAMP levels and cAMP phosphodiesterase activities has been determined in the quail oviduct and in the mouse uterus. In the quail, tamoxifen (1 mg/kg daily for 3 days) had no effect on oviducal growth but significantly increased cAMP concentration (+49%). Injected concurrently with estradiol, tamoxifen completely inhibited oviduct growth as well as the increase of cAMP phosphodiesterase activity induced by the hormone alone and increased cAMP concentration (+229% over estradiol treated group). In the mouse, estradiol and tamoxifen displayed uterotrophic activity and increased cAMP phosphodiesterase activity. In both groups, cAMP concentration was greatly reduced (-76% in estradiol treated group; -86% in tamoxifen treated group). The opposite regulation of cAMP levels in the quail oviduct and the mouse uterus by tamoxifen reflected large differences in the contribution of calmodulin-dependent and -independent forms of phosphodiesterase to the hydrolysis of cAMP in the two models and the fact that tamoxifen stimulated the activity of the calmodulin-independent isoenzyme, while it competitively inhibited the activation of the calmodulin-dependent isoenzyme by calmodulin. Several lines of evidence strongly suggest that the regulation of cAMP levels is involved in growth-inhibiting or growth-promoting activity of tamoxifen.

Changes in cAMP phosphodiesterase activity and cAMP concentration during mouse preimplantation development.

Cyclic nucleotide phosphodiesterase (PDE) activity and cAMP amounts were measured in mouse preimplantation embryos at the 1-cell, 2-cell, 8-cell/morula, and mid-blastocyst stages. PDE activity remained constant between the 1-cell and 2-cell stages. It decreased by the 8-cell stage and continued to decrease by the mid blastocyst stage to about 14% of the 1- and 2-cell values. By contrast, cAMP amounts remained essentially constant at 0.05 fmole/embryo (0.3 microM) from the 1-cell to the blastocyst stage and increased to 0.175 fmole in the fully expanded blastocyst that was close to hatching. Measurements of embryo volume indicated that intracellular volume remained essentially constant up to the blastocyst stage. The morphological changes in cell shape that accompany differentiation of the trophectoderm and that are coupled with blastocoel expansion decreased the intracellular volume. This decrease resulted in an increase in the cAMP concentration to about 0.4 microM by the mid-blastocyst stage. Previous studies indicate that either cAMP or TGF-alpha/EGF can stimulate the rate of blastocoel expansion. Although TGF-alpha/EGF can elevate cAMP levels in other cell types, TGF-alpha, at a concentration that maximally stimulates the rate of blastocoel expansion, did not elevate cAMP in blastocysts. Thus, it was unlikely that elevation of cAMP is the mechanism by which TGF-alpha stimulates the rate of blastocoel expansion.

[Widows of victims of Nazi concentration camps: their pathology].

The psychosocial situation of widows and orphans of victims of the Nazi concentration camps in Poland are presented. In 1984, 74 widows of victims from the Auschwitz-Birkenau camp were interviewed. This article describes widows' emotional-behavioral reactions when facing the imprisonment and death of their husbands, their difficulties in adapting themselves to widowhood, different adaptative forms of memories of their married life, and consequences relevant to widows' mental health and family, and social consequences of widowhood.
