Leaves and stems of Capparis erythrocarpos, more sustainable than roots, show antiarthritic effects.

ETHNOPHARMACOLOGICAL RELEVANCE: Capparis erythrocarpos is a medicinal plant used widely in many parts of Africa for the management of pain and inflammatory conditions such as rheumatoid arthritis. Its wide range of use, popularity and high value, make C. erythrocarpos containing products a target for economically driven adulteration. This is made worse, by the use of roots, which are unsustainable plant parts. In addition, the mechanism of anti-inflammation is not clearly understood. AIM OF THE STUDY: Therefore, this study comparatively evaluated the anti-arthritic and analgesic effects of the leaves, stems and roots of C. erythrocarpos, while elucidating the mechanism of anti-inflammation. MATERIALS AND METHODS: Using the complete Freund's adjuvant arthritis model, the antiathritic effects were evaluated. The analgesic effects were determined by measuring responses to Von Frey filament number 9. Effects of C. erythrocarpos extracts on the levels of Interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-α) were determined using ELISA. Haematological and serum biochemical assays were also carried out. RESULTS: The leaf, stem and root extracts significantly reduced paw volumes with ED50 values (mg/kg) of 182.5, 181.5 and 36.4 respectively. The leaf extract at a dose of 100 mg/kg showed substantial analgesic activity with a decrease in the percentage response to Von Frey filament 9. However, there was no significant difference in activities of the leaf, stem and root extracts. Results from ELISA assays show that lower doses of the stem extracts reduce levels of IL-6. Lower doses of all extracts also reduce TNF-α levels. Haematological analysis showed extracts reversed elevated WBC and platelet levels. Toxicity evaluation with kidney and liver function tests indicated no significant differences between the treatment and control groups. CONCLUSIONS: The leaves and stems, just as the roots, have antiarthritic and analgesic effects and can be used as more sustainable alternatives to the roots. This will support the continuous growth of the industry that has developed around C. erythrocarpos.

Assessment of psychological barriers to cervical cancer screening among women in Kumasi, Ghana using a mixed methods approach.

BACKGROUND: Cervical cancer is the leading cause of cancer death among women in Ghana, West Africa. The cervical cancer mortality rate in Ghana is more than three times the global cervical cancer mortality rate. Pap tests and visual inspection with acetic acid wash are widely available throughout Ghana, yet less that 3% of Ghanaian women get a cervical cancer screening at regular intervals. OBJECTIVE: This exploratory study was to identify psychological barriers to cervical cancer screening among Ghanaian women with and without cancer using a mixed methods approach. METHODS: Semi-structured interviews were conducted with 49 Ghanaian women with cancer and 171 Ghanaian women who did not have cancer. RESULTS: The results of the quantitative analysis indicated that cancer patients where not more likely to have greater knowledge of cancer signs and symptoms than women without cancer. Analysis of the qualitative data revealed several psychological barriers to cervical cancer screening including, common myths about cervical cancer, misconceptions about cervical cancer screening, the lack of spousal support for screening, cultural taboos regarding the gender of healthcare providers, and the stigmatization of women with cervical cancer. CONCLUSION: The results of this study can be used to inform the development of culturally relevant cervical cancer education interventions aimed at addressing the psychological barriers to cervical cancer screening perceived by Ghanaian women.
