Records maintained indicate that Department of Legal Medicine, Kurume University School of Medicine has handled 1,275 cases in total including 1,157 judicial autopsies and 118 cases other than those during the period of 24 years and 3 months (Jan 1963-Mar 1987). (1) Judicial autopsy cases Infanticide: 86 cases (7.4%, 40 male, 44 female and 2 sex unidentified cases), and a total number of autopsies carried out on other than infanticide were 1,071 cases (92.6%, 743 male and 328 female cases). The 1,071 cases were further brokendown into 496 homicidal, 278 traffic accidental, 169 except-traffic accidental and casualties, 74 natural death, 44 suicidal, 9 accidental poisoning death groups, and 1 unidentified case. The cases and means of homicidal cases were classified by cutlery and pointed weapons: 243 cases, strangulation and throttling: 104 cases, blunt or similar ones: 96 cases, fire arms (pistol or hunting gun): 35 cases, poisoning: 8 cases, murder by fire: 4 cases, and 6 other cases. (2) Investigations with exception of judicial autopsy cases. Determination by 46 substance (blood-stains, murderous weapons and others): 38 cases by parentage, 21 cases by documents (clinical anamnesis, clinical diary and testimony records), and other 13 cases. (3) Some remarks to be taken account in performance of investigations for adequate determination.

The purpose of the present study was to examine whether there were some differences between metabolic responses induced by carbon monoxide (CO) poisoning and those by hypoxic hypoxia. Significant decrease in cytochrome oxidase (COX) activity in heart and liver was observed during acute exposure, while no change was observed in brain. When the control of respiration was investigated, cerebral energy homeostasis was maintained even after severe exposure. In order to document this phenomenon we measured blood flow in liver and brain, but increase in cerebral blood flow was not observed and the experiments failed to show a relationship between cerebral homeostasis and blood flow. The prolonged exposure to CO and hypoxia resulted in an increase in COX and these responses were obviously considered to be adaptive to chronic exposure. From the results of acute and chronic exposure it is considered to be difficult to determine if CO has the direct effect on the respiratory chain. Further studies of the mechanism of the CO toxicity may be necessary.

Out of a total number of judicial autopsies handled in the Department of Legal Medicine, Kurume University School of Medicine during the period from Jan. 1963 to Mar. 1987, the traffic accidental death was recorded 278 cases including 216 cases for male and 62 cases for female respectively being specified as followings: 1) Victims-pedestrians: 168 cases, violent falling from two-wheelers (bicycle or motor-cycle, caused by the rider's faults: 21 cases, collision between two-wheelers in motion and motorcar: 50 cases, motorcar in motion: 30 cases (18 drivers and 12 fellow passengers), airplane accident: 1 case, railroad accident: 1 case, and 2 cases other than those. 2) Judicial autopsies specified by the month. Jan-31 cases, Feb, Mar, Jul and Dec-26 cases each, Oct-25 cases, May and Sep-24 cases each, Apr-20 cases, Jun and Nov-17 cases each, and Aug-16 cases. 3) Frequency of accidents specified by the time. 0 hr-0600 hrs: 78 cases, 0600 hrs-1200 hrs: 40 cases, 1200 hrs-1800 hrs: 34 cases, 1800 hrs-2400 hrs: 119 cases and unidentified hrs: 7 cases. 4) Under the influence of liquor 110 cases in total or 39.6% including 108 cases by male and 2 cases by female. 5) In addition to the primary impact injuries some remarks to be taken account in performance of judicial autopsies were discussed.

The present report is concerned with the transmission electron microscopic observations of the consumed hairs in an Australian lobster's stomach. The lamellar cuticles of these hairs were observed and their minimum diameters of melanin granules of cortices were measured by an imaging analyzer. The lamellar cuticles of these hairs consisted of two or three layers and there was no significant difference between them and Aberdeen Angus's hairs in mean the minimum diameters of melanin granules of cortices. Consequently, these hairs in an Australian lobster's stomach were identical to Aberdeen Angus's hairs.

A total number of judicial autopsies conducted in the Department of Legal Medicine, Kurume University School of Medicine during the period of Jan 1963 and Mar 1987 was recorded 1,157 cases including 40 cases caused by the fire arms. This indicates 3.4% of total numbers of death resulting from subject accidents, and the outline thereof is following. 1) Murder case-35, accidental case-5, suicide case-none. 2) Lethal weapons used for the murder: Pistol-26 cases, hunting gun-8 cases, joint use of illicitly hand-made fowling piece and pistol-1 case. All 5 accidental cases of the above were caused by wrong use of hunting guns. 3) The age of victims: Thirties-17 cases, Forties-10 cases, Fifties-4 cases, Teens-4 cases. Twenties-3 cases, one year and downward and from sixty years up-1 case respectively. 4) The entry wound and exit wound caused by the use of fire arms and other several matters in regard to medico-legal investigations and views thereof were taken up in consideration from various angles.
