Studies on rigor mortis

Abstract In a physical investigation of the gastrocnemius muscles of rats killed and kept at about 20°C, rigor mortis was complete at 5–6 hours post mortem . This fact was confirmed by electronmicroscopic investigation of the myofibrils of the gastrocnemius muscles of these rats, especially by the A:I band ratios and the diameters of the myofilaments.

[The racial differences of plasminogen A gene (PLG* A) frequencies].

The present authors investigated racial differences of PLG* A frequencies by literature search. From the results of these investigations it was seen that the frequency of Mongoloids was higher than those of Negroids and Caucasoids, and the frequency of Negroids and that of Caucasoids was almost equal. There is a great variation in the distribution of PLG* A in Negroid and Caucasoid populations. Further studies are necessary to obtain more data regarding PLG* A frequency.
