Osteoblast cells have a capacity to produce estrogen from androgen. It is known that inflammatory cytokines in bone increase during estrogen deficiency. In the present study, the effect of interleukin-1beta (IL-1beta) on aromatase (Arom) activity in human osteoblast-like cells (HOS) was investigated. We also investigated the effect of IL-1beta and estradiol (E2) on cell proliferation in HOS. [(3)H] water method was employed to measure Arom activity. Expression of Arom mRNA was determined by the reverse-transcription polymerase chain reaction (RT-PCR) method. The PCR products were confirmed by Southern blot analysis. Cell proliferation was measured by an ELISA-bromo deoxyuridine (BrdU) kit. Addition of IL-1beta increased Arom activity in a dose-dependent manner and addition of IL-1beta (10 ng/ml) resulted in 40% greater activity than control. Addition of 500 ng/ml of human recombinant IL-1 receptor antagonist neutralized the increased Arom activity to control level. Stimulation of Arom mRNA expression by IL-1beta was also found. IL-1beta and E2 stimulate osteoblastic cell proliferation significantly. These findings suggest for the first time that IL-1beta stimulates Arom activity through the IL-1 receptor and also cell proliferation in osteoblast-like cells. It is also demonstrated that this stimulatory effect may be through the IL-1 receptor. Cell proliferation stimulated by IL-1beta was reduced by the addition of the Arom inhibitor fadrozole-HCL (CGS-16949A). These results imply that IL-1beta has a stimulatory effect on estrogen formation and sequentially cell proliferation in bone, and this mechanism may play an important role in osteoblastic function especially in postmenopausal women.

Most understandings of globalisation assume a flattening of the cultural terrain. In contrast, this paper, using examples from Africa, Indonesia, Malaysia, Japan and Canada, demonstrates a more complex interaction between traditional cultural practices and modern communication forms. The new information technologies enable universal access to authentic local voice. Archiving social and cultural practices provides for cultural continuities and reflexivities: this has historically been the business of museums, universities, and indeed oral traditions of song and poetry. New information technoloigies enable the routine archiving of social and cultural practice at a minimal cost through hypertext, web pages and universal access. The "globalisation of culture" so often discussed needs to be reframed with reference to this highly overlooked indigenous capability to archive own culture. This paper attempts to provide such a reframing.
