ПРОМЕНИ В АКТИВНОСТТА НА НАДБЪБРЕЧНИТЕ ЖЛЕЗИ ПРИ ЕКСПЕРИМЕНТАЛЕН АРТРИТ
Full text linkА report is given of the experimental studies carried out on rats in which experimental arthritis is caused bу means of triple intravenous injection of hemolytic streptococci culture. Following each culture injection the adrenal activity was checked bу assessing the quantity of ascorblne acid found in the adrenal glands. It is estblished that following the first injection of the culture, the adretnal activity is intensified, after the second - it drops and after the third it is again increased. This phase nature of the adrenal activity is in compliance to the arthritis clinical symptoms in the experimental animals
БИОХИМИЧНИ ИЗСЛЕДВАНИЯ НА ОЗВУЧЕНИ КОКОШИ ЕМБРИОНИ, ЗАРАЗЕНИ С ГРИПЕН ВИРУС
Full text linkThe allantois liquid was investigated of treated with ultrasound (bу means of ultrasoпic apparatus at 400 W and 800 kiloherz) and infected with iпfluenza virus chick embryos for the determination of: рН, presence of ашinо acids and phosphatase activity. The bооd of the embriyos was studied for alkaline phosphatase. The livers and chorio-allantois membranеs of the same eшbryos were investigated for ribonucleic acid (RNA) and Desoxyribose nucleic acid (DNA).The results of the experiшeпts showed that:1. The concentration iпdices of the hydrogen ions in the allantois fluids from treated with ultrasound and infected chick embryos vary between 5,5 and 6,0, whereas in those siшilarly treated but not infected - between 5,5 and 7,0.2. The highest average index оf the acid plюsphatase in blооd is obtained in chick embryos treated with ultrasound оn the 7th day after incubation.3. Difference between the infected and noninfected, treated with ultrasoundchick embryos as to amount of amino acids present in the allantoisliquids is not noted.4. Ribonucleic acid in mg per cent R dry weight is higllest in the treatedwith ultrasound and infected chick embryos.5. RNK in mg per cent R dry weight in the chorio-allantois membranes of chick embryos, treated with ultrasound оn the 10th day after incubation and not infected is higher as compared to that in the accordingly treated eшbryos оп the 9th day after incubation.6. Desoxyribose nucleinic acid in mg per сепt dry weight from the liver is highest in the infected chick embryos, treated with ultrasound оn the 10th day.7. DNA in the chorio-allantois membrаnеs in mg per сепt R dry weight from treated with ultrasouпd and not infected chick embryos is highest in those treated with ultrasonic waves on the 10th day
ДИШАНЕ НА МОЗЪЧНИ ХОМОГЕНАТИ ОТ ТРЕТИРАНИ С ВИТЕСТРОЛ ЖИВОТНИ
Full text linkThe experimental material presented shows that the vitestrol (hexestrol, sinestrol) exerts definite influences оп the oxygen consummation bу cerebral tissue. As regards cerebral homogenates, in nearly half of the experimental aпiшals (44 per cent) inoculated оnе and а half to two and а half hours prior to the experiment with vitestrol, а reduclion is observed involving mainly the endogenous respiralion. Concerning the remainder оf the animals, the alterations marked show clear tendency towards а slight stimulation оf breathing which changes however are in the normal fluctuation limits.In the later phase of vitestrol action (7-13 days after administration) its influence оn brain respiration is manifested bу strong activation and maintaining the breathing effect. It is stressed in addition, that the breathing activation in this case affects in а greater extent the oxygen consttrnrnation needed for oxidizing separation of glucose and in а lesser extent - for separation оf the respiralion endogenous substrates found in the nervous cell
