Chinese Government Reports Abortion Statistics
Chinese state media on Thursday reported that women in the country have about 13 million abortions annually, the AP/Houston Chronicle reports. According to the China Daily newspaper, the actual number likely is much higher because the 13 million includes abortions performed in hospitals but not unreported procedures performed in rural clinics. Most of the abortions were among single young women who experts say know little about contraception. The paper also said that about 10 million pills for medical abortion are sold annually in the country. China imposed strict population controls in the 1970s that prohibit most couples from having more than one child. For married women, sterilization and the use of intrauterine devices are widely promoted and subsidized. However, Chinese policies typically do not address the needs of unmarried women, even as national attitudes have become more accepting of sex outside of marriage, the AP/Chronicle reports. According to the newspaper, about 62% of the abortions were among unmarried women ages 20 to 29. The Chinese report called the number of abortions "an unfortunate situation" but did not indicate whether the procedures are increasing or decreasing from year to year. National Population and Family Planning Commission official Wu Shangchun is quoted in the report as saying that almost half of the women seeking abortion had used no form of contraception. Wu also said that reducing abortions is a national challenge that requires significant effort. Peking University professor Li Ying said that sex education in China must be improved at the university level and that Chinese parents must do more to teach children about sex (AP/Houston Chronicle, 7/30).

Neural Substrates Of Controlled And Automatic Processes Involved In Empathy For Pain
Seeing others in pain can automatically engage the brain"s empathy systems even if we are not paying attention, according to new research from Mount Sinai School of Medicine presented at the Annual Meeting of the Organization for Human Brain Mapping. The investigators showed people images of hands and feet in painful or non-painful situations while scanning the brain using magnetic resonance imaging. Under some conditions the subjects paid attention to whether the situation was painful, while in other conditions they paid attention to other aspects of the images. The results showed that a brain area called the insula responded to pain even if the subject was not paying attention to pain, while another area called the anterior cingulate cortex was important for the voluntary control of empathy for pain. The research provides a better understanding of how the social brain responds to others" pain.

New Research Discovers Link Between Smoking And Brain Damage

New research which suggests a direct link between smoking and brain damage will be published in the July issue of the Journal of Neurochemistry. Researchers, led by Debapriya Ghosh and Dr Anirban Basu from the Indian National Brain Research Center (NBRC), have found that a compound in tobacco provokes white blood cells in the central nervous system to attack healthy cells, leading to severe neurological damage. The research centers on a compound known as NNK, which is common in tobacco. NNK is a procarinogen, a chemical substance which becomes carcinogenic when it is altered by the metabolic process of the body. Unlike alcohol or drug abuse NNK does not appear to harm brain cells directly, however, the research team believe it may cause neuroinflamation, a condition which leads to disorders such as Multiple Sclerosis. "Considering the extreme economical and disease burden of neuroinflammation related disorders, it is extremely important from a medical, social and economic point of view to discover if NNK in tobacco causes neuroinflammation" said Ghosh. To prove if such a link exists the team conducted two types of tests, one outside of a living host in glass and one in laboratory mice. The team used blot analysis techniques which showed that the introduction of NNK resulted in a clear increase in proinflammatory signaling proteins, proinflammatory effector proteins and other stress related proteins. Increased levels of proinflammatory cytokines, which act as molecular messengers between cells, were also detected. This shows that NNK provokes an exaggerated response from the brain"s immune cells, known as microglia. Microglia cells act as "destroyers" for the brain by attacking damaged or unhealthy cells. However, when provoked by NNK these cells start to attack healthy brain cells rather than the unhealthy cells they are supposed to attack. "Our findings prove that tobacco compound NNK can activate microglia significantly which subsequently harms the nerve cells," said Basu. While other harmful side effects of smoking, such as lung disease, usually derive from tar or smoke this research suggests damage is not confined only to smoking. NNK is present in all forms of tobacco and therefore it can also enter the body through chewing. The study also suggests that second hand smoking may lead to the same neuroinflamation conditions. Concentrations of NNK in tobacco can vary from 20-310 nanograms in cigarettes. However, NNK is also present in the smoke itself, meaning that smoke-filled air indoors may contain up to 26 nanograms of NNK. This means that both direct and second-hand smoking can lead to substantial measures of NNK intake. "This research sheds light on the processes that lead to nerve cell damage in those who smoke cigarettes or consume tobacco products on regular basis," said Ghosh. Wiley - Blackwell
