China's 'Omnidirectional Diplomacy': Cooperation with all,Emphasis on Major Powers

In the first half of 2001, China's relationship with the two economic power houses, the US and Japan, was anything but smooth. Tomoyuki Kojima, professor of political science and dean of policy management at Keio University describes the principle of China's foreign policy as ''omnidirectional'' diplomacy. The strained relations with the US and Japan, however, were contradictory to this principle which emphasizes international cooperation with a focus on world powers. In the following article, he examines the main reasons for China's problems with both countries. At the time of writing, Shanghai is to host the 2001 Asia-Pacific Economic Cooperation forum in October, China is poised to enter the World Trade Organization and Beijing had also won the bid to host the 2008 Olympics. As China becomes more and more internationalized, Kojima argues that the emphasis on cooperation will be perceived as having been of vital importance.     

Abnormally high alcohol concentration in the heart blood

A 46-year-old male alcoholic whose whereabouts had been unknown for about a month was found dead at the foot of a cliff 31 m deep. Fractures of the mandible, thorax and left patella were found at autopsy, but fatal injury to the brain or other organs was not observed. The alcohol distribution was 7.44 mg/g in the heart blood, 13.91 mg/g in the left thoracic cavity fluid and 1.88 mg/g in the urine. The high ethanol concentration in the heart blood was assumed to be mainly due to the diffusion of ethanol from the contents of the stomach and postmortem production of ethanol. It was decided that the cause of death was not acute alcohol intoxication but respiratory failure caused by fractures of the thorax.     

A case of Ebstein's anomaly with double mitral valve

A 5-month-old male infant with no history of serious illness died suddenly and unexpectedly. He was found dead under a heavy 'futon', a coverlet, which covered the whole of his body. As it was suspected he may have been smothered, a medicolegal autopsy was performed, and it was discovered that the infant had Ebstein's anomaly with double mitral valve. The cause of death appeared to be due to heart failure caused by this congenital heart disease.     

Evaluating the Efficiency of Primer Extension Capture as a Method to Enrich DNA Extractions,

In this study, we sought to document the efficiency of primer extension capture (PEC) as a method to enrich DNA eluates of targeted DNA molecules and remove nontarget molecules from pools containing both. Efficiency of the method was estimated by comparing number of “copies in” to “copies out” by quantitative polymerase chain reaction. PEC retention of DNA targets ranging 109‐288 base pairs (bps) in length was 15.88–2.14% (i.e., loss of 84.12–97.86% of target molecules). Experimental modifications of the PEC method resulted in no significant improvements. However, the benefit of PEC was revealed in its ability to remove most nontarget DNA molecules (99.99%). We also discovered that many (56.69%) of the target molecules are “lost” prior to their immobilization on the streptavidin‐coated beads. These estimates of methodological efficiency are directly comparable to previous ones observed following “fishing” for DNA, an alternative method for DNA enrichment.     

The G8 Summit and Japan

In the following article, Akira Kojima, managing director and editorial page editor of the Nihon Keizai Shimbun, evaluates the 2000 Kyushu-Okinawa Summit. In contrast to those critics who contend that the summit has deteriorated into an irrelevant and redundant international gathering, Kojima argues that the summit is even more important than it has ever been. In this evaluation of the 2000 G8 Summit, he outlines the role of the summit and, in particular, explains the significance of the summit for Japan, both for politicians and for the general public. He also discusses the rationale for the choice of Okinawa as the venue for the last G8 Summit of the twentieth century.     

Traumatic rupture of intracranial vertebral artery due to hyperextension of the head: reports on three cases

In three cases of fatal basal subarachnoid hemorrhage due to rupture of the normal intracranial vertebral artery, the ruptures appeared to have been caused by overstretching of the vertebral artery from traumatic hyperextension of the head. In the first case, that of a 31-year-old male pedestrian who, while intoxicated, had been hit from behind by a car, symmetrically located bilateral complete and incomplete tearing of the vertebral arteries was found. In both of the other two cases, involving women aged 37 and 51 found dead after receiving fist blows to the face while intoxicated, complete rupture of the vertebral artery was found. The blood alcohol concentrations of the three cases ranged from 1.6 to 1.7 mg/g at autopsy.     

Experimental study on postmortem formation of carbon monoxide

Rats were drowned and kept immersed for 1 month in either boiled city water, or boiled or unboiled fresh water collected from a river. A small amount of carbon monoxide (CO) formed after death and a low carboxyhemoglobin (HbCO) saturation was found in blood and thoracic cavity fluid of the animals immersed in boiled city water and in boiled fresh water. A considerable amount of CO and a high HbCO saturation was observed in blood and thoracic cavity fluid in two out of three rats immersed in unboiled fresh water at 4-6 degrees C, and in one out of three at 6-16 degrees C. It is suggested that microorganisms in the water, in which the rats were drowned and kept immersed, and low temperatures of around 5 degrees C during storage, played an important role in the postmortem formation of carbon monoxide.     

A case of death from prothiophos poisoning

A 62-year-old male, a farmer, who had ingested prothiophos (Tokuthion), died after 21 h of intensive care. Prothiophos in the tissues of the victim was extracted and purified by Extrelut column extraction. A gas chromatograph equipped with a flame photometric detector, and a gas chromatograph-mass spectrometer were used to detect prothiophos. The concentration of prothiophos was 10.9 micrograms/g in the brain, 8.6 micrograms/g in the kidney, 418 micrograms/g in the liver, 2.96 mg/g in the gastric contents and 4.69 mg/g in the intestinal contents. The case history and the distribution of prothiophos indicated that the cause of death was acute prothiophos poisoning.     

Cyanide distribution in five fatal cyanide poisonings and the effect of storage conditions on cyanide concentration in tissue

The cyanide distribution in five fatal cyanide poisonings was analyzed by the pyridine-pyrazolone method using a Conway diffusion cell. In order to study the effect of storage conditions on cyanide concentration in tissue samples, the cyanide concentrations were first measured immediately after collection of the samples at autopsy, then measured again after storage in a refrigerator (4 degrees C) or in a freezer (-20 degrees C) for periods ranging from 1 day to 3 weeks. Concentrations in all but three of the blood samples stored at 4 degrees C or -20 degrees C increased, with concentration ratios based on measurement made before and after storage ranging from 0.71 to 1.46. The concentrations in the liver, kidney, and brain samples either increased or decreased, with ratios of from 0.2 to 8.8. The concentrations in the stomach contents samples decreased rapidly at 4 degrees C, but hardly changed at all at -20 degrees C.
