What does Halobacterium tell us about photoreception?

A photosensory mechanism is proposed for Halobacterium halobium based on the observation of light-induced motor responses. Possible mechanisms of signal transduction in Halobacterium are discussed. Bacteriorhodopsin and the visual pigment rhodopsin are compared with respect to their structural and functional properties. The conclusion is drawn that Halobacterium may help to understand primary photochemical events of rhodopsin rather than the transduction mechanism of visual photoreceptors.

[Excessive generalized fat embolism in acutely dystrophic fat liver (author's transl)].

We have reported about a 63 year old woman, who, 1 to 2 hours after a meal containing mushrooms, became acutely ill, sank into uncontrollable shock, and died 24 hours later. Autoptically was found an acute yellow liver dystrophy in a previously existing fatty liver. Etiologically an intoxication by Amanita phalloides could be excluded as well as any other exogenic intoxication. The cause of the acute liver dystrophy was most probably a fulminant virus hepatitis. The decay of the fatty liver cells led to an unusally severe generalized fat embolism, which morphologically is regarded as the cause of death.

[Unusual fatalities caused by glass splinter injury].

In the case of a thorax stab wound and an intrapulmonal position of the glass fragment (fall from a ladder into a glass door) an extrathoracic cardiac massage had been carried out. The result of which, an extremely unusual "reanimationtrauma" and the problems connected with it are discussed. In another case of a stab wound of the right iliacal vessels and the position of the glass fragment in the minor pelvis (jump through a thermopane glass of a door, followed by a fight) investigations were first conducted because of the suspicion of manslaughter. The autopsy, however, completely excluded death through fault of another. Further an unusual figured glass cut wound on the left side of the head (fall into a glass brick wall) led to death through gradual bleeding. The question arose whether death was caused by failure to give assistance.

[Hanging: suicide or homicide?].

Death by Hanging: Suicide or Homicide. Six cases of homicidal hanging and murder presented as suicidal hanging are recorded. Suspension followed strangulation by ligature or throttling and head injuries in 4 cases. Distinction between homicide and suicide was easy in 5 cases: two of the perpetrators gave themselves up to the police, one committed suicide immediately after he had hanged his 15 year old daughter; in two cases tracks of blood, heavy injuries of the victims, and traces of robbery were obvious. Unless the victim is an infant or an adult person incapacitated by drink, disease, or drugs, or unless there are several assailants murder is difficult to accomplish. Distinction between murder and suicide may be impossible by an examination of the body alone. Detailed investigation of the scene, reconstruction of the position of the suspended body, examination of the rope, the knots, the direction of the fibres on the rope may serve to discover homicidal hanging. - Compared to suicidal hanging homicide has a frequency of about 1% in our autopsy material. However, we cannot estimate the number of obscure cases.

[Gunshot fatalities in connection with hunting and hunting rifles--causes, prevention and expert evaluation].

Fatalities due to gunshot injury by hunting firearm or during hunting, that had been investigated in the Institute of Legal Medicine of Hamburg University during the last 20 years, were retrospectively analyzed from the view points of epidemiology, morphology, criminology and ballistics. Thirteen accidents, 23 suicides and 13 homicides were included in this study. Female victims were observed in only 2 cases. In the accidents, the age of the most victims ranged from 30 to 60 years. Seven of 13 accidental victims killed themselves; remaining 6 were shot by other hunters. Nine accidents happened during hunting. The most frequently used firearm in cases of suicide and homicide was a shotgun whereas accidents preferably occurred with rifles. In some homicidal cases pistols were also used. The entrance wound was localized mostly in the head, neck or breast. Shooting in the mouth was observed in many suicidal cases. Although many victims were shot in the hunting ground, 15 of 23 suicides were performed at home. In 3 homicides which occurred in the hunting ground, the murderer committed another crime with the robbed hunting firearm of the victim. Three accidents occurred during training in the shooting-gallery. Blood alcohol concentration (BAC) was determined in 28 cases. Different degrees of drunkeness were observed in 2 self-inflicted accidents, 5 suicides and 2 homicidal cases. No BAC determinations were performed on the shooters. Ten case histories are presented. The discussion concentrates on the effect of the kind of firearm and ammunition on the appearance of the wound, prevention of accidents, and the principles of reconstruction, especially concerning the differentiation accident/suicide. The forensic expert investigating gunshot injuries during hunting should have personal experience in this field. The most frequent cause of accidents was careless handling of the loaded firearm and violation of invulnerable rules for safety during hunting.
