4-Bromobenzaldehyde thiosemicarbazone Schiff base （4-BBTS） and its Cu（Ⅱ）, Zn（Ⅱ）, Co（Ⅱ） and Ni（Ⅱ） complexes were synthesized and characterized by elemental analysis, UV, IR, MS, ^1H NMR, and molar conduct...4-Bromobenzaldehyde thiosemicarbazone Schiff base （4-BBTS） and its Cu（Ⅱ）, Zn（Ⅱ）, Co（Ⅱ） and Ni（Ⅱ） complexes were synthesized and characterized by elemental analysis, UV, IR, MS, ^1H NMR, and molar conductivity. Using disc diffusion method, the antibacterial activity tests were conducted. The results revealed that the ligand as well as all the complexes exhibits good antibacterial activities against E. Coli. and S. Aureus. Moreover, Cu（Ⅱ） complex shows the best antibacterial activity, which provides beneficial reference for studying the relationship between the structures and performances.展开更多

We then investigated characteristics of difficult pregnancy cases with measurement of body temperature and observation of basal body temperature (BBT) charts. Thirty-three patients had acupuncture every week for more than 2 years and 17 of them delivered. At the same time, their cutaneous body temperature was measured at five locations. Moreover, patients and acupuncturists had a weekly discussion of the patient’s BBT chart. The delivery group showed more balanced and higher cutaneous body temperatures than the miscarriage and no pregnancy groups. The delivery group showed a smooth increase in the BBT chart while the miscarriage group showed a specific pattern in shifting temperatures from low to high zones. Acupuncture might suppress excess sympathetic dominance, which induced hyperthermia as well as interruption of pregnancy. Additionally, weekly discussion and medical advice could help patients. However, further study of males, healthy women, or larger, comparative studies exploring the social and cultural background of other countries were needed to add support to these factors.展开更多
