Inhibitory action of chlorophyllin of autosome recessive lethals induced by irradiation; Accion inhibidora de la clorofilina de letales recesivos autosonicos inducidos por irradiacion

Abstract

The chlorolin is a sodium salt of the chlorophyll that has a strong protective action of the damage induced by different agents so much physical as chemical. In Drosophila there is reported this effect in somatic cells. In contrast, in germinal cells using tests with the sexual chromosomes has not been found such inhibitory action. For this reason, in this occasion we will refer to the effect of the lethality induced in autosome chromosomes, in particular to the chromosome II of this species. For such effect groups of males of the line Canton-S its were pre-treated for 24h with or without 69 mm of CCS and later on treaties with or without 40 Gy of gamma irradiation. The males were then subjected to the technical Cy L / Pm for the detection of recessive lethals. In the third generation the respective counts of the descendant of each one of them to determine the corresponding categories for each extracted chromosome were made. To be mendelian crosses it is expected for a normal chromosome a proportion 2:1 of individuals with genotype Cy L / +: +/+. The absence of individuals +/+ it is indicative of a lethal gene, until 10% of these  More>>

In the third generation the respective counts of the descendant of each one of them to determine the corresponding categories for each extracted chromosome were made. To be mendelian crosses it is expected for a normal chromosome a proportion 2:1 of individuals with genotype Cy L / +: +/+. The absence of individuals +/+ it is indicative of a lethal gene, until 10% of these individuals of each male's total descendant, it is considered that is carrying of a semi lethal gene. The sum of lethal and semi lethals constitutes the category detrimental. The obtained results indicated that the pre-treatment with CCS reduces in a significant way the frequency of induced lethals by 40 Gy of gamma rays. The fact that an effect inhibitor has not been observed in the test of recessive lethal bound to the sex obtained previously, it contrasts with the effect observed in the chromosome II, results of this study and with the one observed in the chromosome III in somatic cells. The above-mentioned shows a differential action of the CCS between sexual chromosomes and autosomal before the effect of the gamma radiation. At the moment we don't have an explanation to these evidences. To evaluate the action of the chlorophyllin on the damage caused by the radiation, it was into accothe presence of lethal and semi lethals autosomal. One observes this way that even without the use of the radiation the semi lethals frequency is diminished when the chlorophyllin is applied, in this case the decrease was significant and although there was decrease in the case of the irradiated group this it was not significant; in the case of the lethal ones it happened the opposite it was not significant in radiation absence on the contrary elevate the frequency of this type of genes, however, before the radiation and with pre-treatment with chlorophyllin this it reduced the frequency of autosomal recessive lethals significantly. This is important because in the case of bound recessive lethals recessive to the sex this doesn't happen. (Author)}
