Opis:
It bas been found that trypsin and α-chymotrypsin inhibitors isolated from Ascaris suum act embryotoxically and teratogenically on White Leghorn clucken embryos. Mortatity rate for the chicken embryos on day 15 of incubation was 45.0 ± 3.5% after injection of trypsin inbibitor and 44.0 ± 3.5% after adminstration α-chymotrypsin inbibitor. Gross examination of surviving embryos and their dissection revealed pathological changes (abdominal dropsy, umbilical hernia, subcutaneous oedema, hemoperitoneum, hemopericardium), symptoms indicating retardation in growth (lack of down, retarded ossification of long bones, decreased mean body weight) as well as malformations (schistocelia, micrognathia, cyclopia, crossed beak, cranial deformities) after injection of inhibitors from Ascaris. The highest incidence of embryos with pathological changes and malformations was found after administralion of α-chymotrypsin inbibitor. The most commonly occurring abnormality was schistocelia (21.4 ± 3.88%). Growth malformations were not found in the control groups. The trypsin and α-chymotrypsin inhibitors present in Ascaris homogenate have a significant disturbing effect on the development of the chicken embryo.

Opis:
In this study, maternal toxicity and developmental effects of exposure to Ascaris trypsin inhibitor were evaluated in mice. Pregnant BALB/c females were injected intraperitoneally by Ascaris inhibitor /AIT/ at 200, 300, and 400 mg/kg body weight/day, on days 12 to 15 of gestation (stage of fetal development). At day 19 of pregnancy, uterine contents were inspected for implantation sites, early resorptions (moles), living fetuses and dead fetuses. The living fetuses were weighed and examined for external, internal and skeletal abnormalities. The results showed that AIT induced maternal toxicity, evidenced by maternal deaths, abortions, bleeding from uterus and reduced body weight gain as compared to control (p <0.01). There were no differences between the control group and the rest of all groups investigated for total implantation sites and early resorptions. Fetotoxicity was observed as shown by the decrease in the number of living fetuses and mean fetal weight, a high rate of intrauterine fetal deaths, delayed skeletal ossification, occurrence of pathological changes of fetal organs and tissues. Only one type of congenital malformations (hydronephrosis) was noted in fetuses after injection of higher doses of AIT.

Opis:
BALB/c mice were given daily doses of 40-80 mg of Ascaris chymotrypsin inhibitor /AChl/ per kg body weight from 12" until 15" day of gestation (stage of fetal development). It has been found that injection of AChI disturbed the course of pregnancy (bleeding from uterus, abortions, decreased body weight gain as compared to control /p < 0.05/). AChI exhibited embryotoxic effects (a high rate of intrauterine deaths, decreased number of living fetuses and mean fetal weight, delayed skeletal ossification, induced pathological changes of fetal organs and tissues). Congenital malformation (hydronephrosis) was noted in fetuses after injection of higher doses of the chymotrypsin inhibitor from Ascaris.

Opis:
Administration intraperitoneally of the Ascaris α-chymotrypsin inhibitor (40-300 mg/kg/day.) at a late stage of organogenesis (8-12 days of gestation) disturbed course of mouse pregnancy. The low doses of α-chymotrypsin inhibitor (40-80 mg/kg/day) significantly decreased the number of live fetuses per litter, increased the number of fetal resorptions. The symptoms of matemal toxicity that occurred after administration of the highest doses of the inhibitor (80-300 mg/kg/day) to pregnant mice included: decreased body weight gain as compared to control, vaginal hemorrhage, intrauterine resorption of litters, abortions, altered behaviour of animals immediately after injection and death. There is a linear interrelationship between the logarithm of the doses of the inhibitor and mortality of pregnant mice. The DL50 value of the inhibitor for female was 116 mg/kg /day (confidence interval: 95.5-140.0 mg/kg/day).

Opis:
Trypsin inhibitor, isolated from Ascaris suum tegument reduces in vitro proteolytic activity (pH 7) of lungs and kidneys post-nuclear fractions of guinea pigs with larval ascariosis, pigs after subcutaneous ascarid homogenate administration as well as the activity in control groups. The comparative analysis of effect curves of trypsin inhibitor on the organ proteases revealed stronger reduction of the activity of post-nuclear lung proteases in ascariosis and of kidneys proteases after the injection of Ascaris homogenate than the inhibition of the fractions activity from respective control groups.

Opis:
It has been found that alpha-chymotrypsin inhibitor isolated from Ascaris lumbricoides suum acts embryotoxically on the Leghorn chicken embryo. An increase in embryo mortality with increasing dose of the inhibitor has been observed after its administration into the yolk sac on day 4, 8 or 13 of incubation. There is a linear interrelationship between the logarithm of the dose of alpha-chymotrypsin inhibitor and the mortality of chickens. The LD50 values foralpha-chymotrypsin inhibitor increased for injections performed at later stages of embryo development. A significant decrease of mean mass of chicks injected with alpha-chymotrypsin inhibitor in comparison with control groups was observed. There was a more frequent occurrence of developmental abnormalities and pathological changes in groups of hatched chicks which received the Ascaris inhibitor.
