An autopsy case of human skeletal remains with a numerical variation in thoraco-lumbar vertebrae.

Unidentified skeletal remains with almost every part of a single body were found in a closed shed; it wore a jacket, pants and underwears. It was brought to Hamamatsu University School of Medicine for autopsy. We estimated the victim to be male, 50-65 years old, 164-168cm high and at 5-10 years after death.

The restriction of all minerals in the diet enhancing paraquat toxicity is regarded primarily as the shortage of Mg.

This study compares the effect of the restriction of Mg with that of all-minerals in the diet on the toxicity of paraquat. To compare the severity of the toxicity, several biological values were examined; kininogen in plasma, thiobarbituric acid reactive substances in liver, Ca level in kidney, and Mg levels in liver and kidney. Osteogenic disorder Shionogi rats that cannot synthesize vitamin C like humans did not display paraquat symptoms after receiving minute amounts of paraquat dichloride, i.

Sensitive determination of pethidine in body fluids by gas chromatography-tandem mass spectrometry.

We have presented a simple and sensitive method for determining pethidine, a narcotic analgesic drug in body fluids by gas chromatography-tandem mass spectrometry (GC-MS/MS). Pethidine and 4'-piperidinoacetophenone (internal standard) were extracted from body fluids with Bond Elut C(18) columns; the recoveries were above 85% for both compounds. The calibration curves for blood and urine showed good linearities in the range of 1.

Traumatic basal subarachnoid haemorrhage caused by the impact of a golf ball: a case report.

A 50-year-old male was hit by a high-speed golf ball on the left lateral side of his neck. He collapsed immediately and was sent to hospital, where he was pronounced dead. The autopsy showed an extensive basal subarachnoid haemorrhage.

Sensitive analysis of alkyl alcohols as decomposition products of alkyl nitrites in human whole blood and urine by headspace capillary GC with cryogenic oven trapping.

The abuse of alkyl nitrites is becoming a serious social problem worldwide. In this report, a simple and sensitive method is presented for the determination of n-butyl alcohol, isobutyl alcohol, and isoamyl alcohol as decomposition products of alkyl nitrites in human whole blood and urine samples using capillary gas chromatography (GC) with cryogenic oven trapping. After heating a whole blood or urine sample containing each alkyl alcohol and t-butyl alcohol [the internal standard (IS)] in a 7-mL vial at 55 degrees C for 15 min, 5 mL of the headspace vapor is drawn into a gas-tight syringe and injected into a GC inlet port.

An autopsy case of a stunt man who jumped into seawater riding a motorcycle: a case report.

We report a rare case of the death of a stunt man who jumped into the sea driving a motorcycle on location for a TV drama. A special ramp had been constructed for the jump. The stunt man and a passenger drove up the ramp at a speed of 60-70 km/h and jumped into the sea from a height of about five metres.

Application of gas chromatography-surface ionization organic mass spectrometry to forensic toxicology.

Surface ionization (SI), which consists in the formation of positive and negative ions along the course of thermal desorption of particles from a solid surface, was first applied as a detector for gas chromatography (GC), GC-surface ionization detection (SID); we developed many new sensitive methods for the determination of abused and other drugs by GC-SID. Recently, Fujii has devised a combination of SI and a quadrupole mass spectrometer and named this system a surface ionization organic mass spectrometer (SIOMS), which is highly selective and sensitive for organic compounds containing tertiary amino groups. We have tried to apply this mass spectrometer to forensic toxicological study; so far we have succeeded in determining important drugs-of-abuse and toxic compounds, such as phencyclidine (PCP), pethidine, pentazocine, MPTP and its derivatives from human body fluids with high sensitivity and selectivity.
