MotherSafe: Review of three years of counselling by an Australian teratology Information Service.

Aust N Z J Obstet Gynaecol. 2009 Apr; 49(2): 168-72Lim JM, Sullivan E, Kennedy DBACKGROUND: MotherSafe was established in January 2000 at the Royal Hospital for Women as Australia's first 'purpose-built' Teratogen Information Service and since then has received over 75,000 calls regarding exposures during pregnancy and lactation. AIM: To describe the patterns of use of MotherSafe over a three-year period. METHODS: Retrospective descriptive epidemiological study using data from the database established at MotherSafe. Records from all the calls logged at MotherSafe between January 2005 and December 2007 were analysed to determine total number of calls, demographic characteristics of callers, including age, caller category and postcode, reason for call, source of referral and type of exposure. RESULTS: A total of 47,138 calls were recorded to the MotherSafe service from January 2005 to December 2007. The majority of calls were regarding exposures in pregnancy (55%) and breast-feeding (38%). Average age of patients was 32.3 years. Of the calls made, 81.9% (38,485 of 46,968) were by consumers (the pregnant or lactating woman herself or a relative). The most common primary exposure categories were: over-the-counter medications (11.3%), psychotropic medication (9.0%), herbal or vitamin products (8.2%), antibiotics (7.0%), gastrointestinal medications (6.8%) and topical products (6.6%). Forty per cent of callers enquired about multiple exposures. CONCLUSIONS: The utilisation of MotherSafe by consumers and general practitioners continues to increase, reflecting the strong demand for a teratogen counselling service that provides high-quality, evidence-based information on exposures during pregnancy and lactation.

MAPK activation is necessary to the apoptotic death of KB cells induced by the essential oil isolated from Artemisia iwayomogi.

J Ethnopharmacol. 2009 Jun 22; 123(2): 308-14Cha JD, Jeong MR, Kim HY, Lee JC, Lee KYAIM OF THE STUDY: Artemisia iwayomogi is a perennial small herbal plant that has long been used as a chemopreventive agent in traditional Korean medicine. Previously, the purified essential oil was isolated from Artemisia iwayomogi, herein named AIEO, and found to contain the active components responsible for the chemopreventive potential of the herb. MATERIALS AND METHODS: This study examined whether or not AIEO has potential chemopreventative effects against cancer using the human oral epidermoid carcinoma cell line, KB cells. The possible mechanism of AIEO-induced apoptosis was also examined. RESULTS: The results showed that AIEO induces the apoptotic death of KB cells, which is mediated by mitogen-activated protein kinases (MAPKs). In addition, AIEO not only induced an imbalance between the mitochondrial Bcl-2 and Bax levels with the concomitant release of Cytochrome c into the cytosol but also induced the activation of caspases and the cleavage of PARP. This induction was significantly suppressed by MAPK inhibitors. Moreover, pretreating the cells with each of the caspase or MAPK-specific inhibitors apparently inhibited AIEO-induced cytotoxicity of KB cells. CONCLUSIONS: These results strongly suggest that AIEO might have cancer chemopreventive and therapeutic potential, which is closely related to its ability to activate the MAPK-mediated signaling pathways with the subsequent induction of a mitochondria- and caspase-dependent mechanism.
