A Phenomenological Study on Lived Experience of Suffering in Suicide Attempters / 정신간호학회지

PURPOSE: The purpose of the study was to understand essential meanings of suffering experienced by suicide attempters. METHODS: Data were collected in 2009 through individual narrative interviews from 7 suicide attempters. Texts from literary works and movies containing suicide were also included as data. Data were analyzed using the hermeneutic phenomenology of van Manen. RESULTS: Thirteen themes were identified in four dimensions. In the dimension of 'lived body', 'unbearably sweet temptation to death', 'body surrendered by emotional damage', 'chaos in life and death', 'squashed body by the heavy weight of life', and 'loss of meaning in life' were identified. 'The black hole, one is not able to get out' represents the experience in the dimension of 'lived space', 'The moment on the edge of a profound abyss' and 'the worst present and hopeless future' represent 'lived time'. In the dimension of 'lived human relation', 'I who am alone in the world', 'fear of being abandoned', 'unbreakable relationship trap', 'I who am not recognized' and 'guilty feeling' were included. CONCLUSION: Results of the study should be helpful in developing personalized suicide prevention programs by showing the various types of suffering deeply ingrained into the personal history of suicide attempters.

Donor Specific Response of Estrogen and Progesterone on Cultured Human Melanocytes

The mechanisms of estrogen and progesterone in human cutaneous pigmentation are largely unknown. The molecular identification of estrogen receptor (ER) and progesterone receptor (PR) in the human melanocytes is of great importance to understand the mechanisms. We performed immunocytochemistry analysis and demonstrated that ER and PR were expressed in the cytoplasms and nuclei of human melanocytes. Reverse transcriptase-polymerase chain reaction (RT-PCR) and sequence analysis confirmed the expression of ER and PR at the transcriptional level. Despite of the presence of ER and PR, the physiological and pregnant levels of estrogen and progesterone showed inconsistent effects on the proliferation and tyrosinase activity of cultured human melanocytes. These results suggest that human melanocytes express ER and PR, which have a donor-specific action in human pigmentation. Further studies are needed to elucidate the induction mechanism and functions of these receptors, and the role of estrogen and progesterone in melanocytes.

Expression of progesterone receptor in human keratinocytes

Despite the various responses of human skin to female sex hormones, cellular and subcellular targets and the mechanisms of action of estrogen and progesterone in human skin are not well understood. The detection of estrogen receptor (ER) and progesterone receptor (PR) in the skin is of great importance to understand the effect of estrogen and progesterone. In primary cultures of human keratinocytes, expression of ER and PR was monitored by immunocytochemistry and reverse transcriptase polymerase chain reaction (RT-PCR). Paraffin embedded skin tissues were stained with monoclonal antibodies to human ER and PR by immunohistochemistry. Cultured human keratinocytes expressed cytoplasmic PR protein and PR mRNA transcripts. By contrast, ER was detected only at the mRNA level. Suprabasal keratinocytes from samples of pruritic urticarial papules, plaques of pregnancy (PUPPP) and psoriasis were stained positively only for PR, while those from samples of erythema nodosum were negative for both ER and PR. Lesional epidermis of PUPPP showed positive PR immunoreactivity, while nonlesional epidermis did not. No other cells in the normal human skin were stained with ER and PR. The present study suggests that by expressing PR human keratinocytes act as targets for progesterone action.
