The experiment was carried out on 20 Swiss male mice divided into experimental (E, n=10) and control (C, n=10) group. E mice were intraperitoneally injected with glucagon (15 μg/kg b.w.) twice daily for eight days, while mice C with 250 μl 0.9% NaCl/mouse (to exclude the injection effect only).In the lysosomal fraction of the liver the activities of acid phosphatase, β-N-acetyl-hexosaminidase, β-glucuronidase, β-glucosidase, lysosomal arylesterase, lysosomal lipase, leucine aminopeptidase and alanine aminopeptidase were determined. Glucagon caused an increase of activity of all studiem enzymes except β-glucuronidase and β-glucosidase, where reduced activities were observed.

The experiment was carried out on 90 Swiss male mice divided into 9 groups (n=10). Over 4, 10 and 14 days mice of three control groups (I-III) were injected with 250 μl 0.9% NaCl solution daily, and those from six experimental groups (A-F) with 250 μl 0.9% NaCl solution containing 20 or 30 mg morphine hydrochloride per kg body weight. The injections were given intramuscularly once a day between 9:00-10:00 a.m. for 4, 10 and 14 days. In the lysosomal fraction of the liver and kidney the activities of acid phosphatase, lysosomal esterase, β-glucuronidase, β-galactosidase, and β-N-acetyl-hexosaminidase were estimated. Morphine increased the activity of all examined enzymes except EL, which activity was statistically proven to decrease in liver and kidneys after 10 days morphine administration in both doses.

The study was conducted on 20 Swiss line male mice divided into two groups – control (n=10) comprised of unselected animals (group C), and experimental (n=10) comprised of mice selected over 24 generations for high live body weight gain (group S). Beginning from day 42 of life mice of both groups received over a period of 14 days a standard pelleted feed containing 16% protein.After 14 days the animals were killed, a lysosomal fraction of liver and kidney cells was obtained and analysed for the activity of acid phosphatase, lysosomal esterase, lysosomal lipase, β-glucuronidase, β-galactosidase, β-glucosidase, β-N-acetylo-hexosaminidase, leucine aminopeptidase, alanine aminopeptidase and cathepsins D and L. In S mice the activities of a majority of the lysosomal hydrolases examined were found to be higher than in C animals.

Celem pracy był przegląd badań i literatury z różnych ośrodków naukowych, dotyczących wpływu liofilizacji na zawartość i właściwości antyoksydacyjne wybranych składników bioaktywnych w owocach aronii czarnoowocowej (Aronia melanocarpa), borówki czernicy (Vaccinium myrtillus), truskawki (Fragaria xananassa Duchesne), maliny (Rubus L.), żurawiny wielkoowocowej (Vaccinium macrocarpon), jeżyny (Rubus L.) i porzeczki czarnej (Ribes nigrum). Surowe owoce charakteryzowały się dużą zawartością polifenoli oraz kwasu askorbinowego, co warunkowało ich aktywność przeciwutleniającą. Z danych literaturowych wynika, że liofilizacja nie wpływa znacząco na zmniejszenie zawartości związków bioaktywnych w badanych owocach. Przedstawione liofilizaty owoców zawierały także cenne karotenoidy (likopen, ß-karoten, luteina, zeaksantyna, rubiksantyna, ß-kryptoksantyna).

Changes in the activity of β-glucuronidase, N-acetyl- β -glucosaminidase, cathepsin D and cathepsin L in the liver and kidney of mice, injected intraperitonealy with 15 µg/kg b.w. of glucagon were investigated. The experiment was carried out on 24 8-week-old mice, whose parents were chosen from random match. The homogenates of the liver and kidney were subjected to differentiate centrifuging, and in the lysosomal fractions of the liver and kidney the activities of β -glucuronidase [β -GlcUr], N-acetyl- β -glucosaminidase [NAG], cathepsin D [Cath. D], and cathepsin L [Cath. L] were estimated. Injection of glucagon caused a decrease in the activity of β -glucuronidase in the liver and kidney, cathepsin L in the liver, N-acetyl-b-glucosaminidase in the kidney, and an increase cathepsin D and cathepsin L in the kidney of mice. The results suggest that exogenous glucagon had a significant influence on the activity investigated lysosomal enzymes. The range of the reaction remained in a relationship with the kind of the organ and type of enzyme.

Used were ninety Swiss mice males divided into 9 groups (n=10). Three control groups [I, II, III] were injected with 0.9% NaCl solution, while six experimental groups (A, B, C, D, E, F) with the morphine hydrochloride. Mice from groups A, C and E were injected with a dose of 20 and those from B, D and F with a dose of 30 mg morphine per kg body weight. In each group, both solutions were administered intramuscularly once a day from 9:00 to10:00 a.m. for 4, 10 and 14 days.In the lysosomal fraction of the liver and kidney the activities of cathepsin D, cathepsin L, alanine aminopeptidase, leucine aminopeptidase, lysosomal lipase, and β-glucosidase were estimated.Morphine led to the increased activity of all examined enzymes except lysosomal lipase, the activity of which dropped in both organs examined.

The investigations were conducted on 20 Swiss male mice, fed a feed containing 16% (control group,n=10) or 10% protein (experimental group, n=10). After 14 days of feeding, sections of liver and kidneys were obtained from all animals and homogenized in order to obtain the lysosomal fraction,in which the activity of the following enzymes was determined: acid phosphatase, lysosomal esterase,lysosomal lipase, β-glucuronidase, β-galactosidase, β-glucosidase,β-N-acetyl-hexosaminidase,leucine aminopeptidase, alanine aminopeptidase and cathepsins D and L. Feed with the protein level reduced to 10% had, compared to the control, a significant and differentiated effect on the activity of enzymes examined, depending on the enzyme type and organ.

The studies have been conducted on 40 male mice. The experiment was connected with the influence of B₁, B₂ and B₆ vitamins on some lysosomal enzyme activities in the liver and kidney. The thiamin injection decreased lysosomal esterase, lysosomal lipase and alanine aminopeptidase activities in the liver; the ryboflavin injection - lysosomal esterase and alanine aminopeptidase, and pyridoxine injection - lysosomal esterase, cathepsin D and L and alanine aminopeptidase. Ryboflavin increased the activity of β-glucuronidase, N-acetyl-β-glucosaminidase, acid phosphatase and leucine aminopeptidase in the liver; pyridoxine N-acetyl-β-glucosaminidase and leucine aminopeptidase activity. Thiamin increased β-glucuronidase, β-galactosidase, N-acetyl-β-glucosaminidase, acid phosphatase, lysosomal lipase, cathepsin D and L, leucine aminopeptidase and alanine aminopeptidase activity in the kidney; ryboflavin - β-glucuronidase, β-galactosidase, N-acetyl-β-glucosaminidase, acid phosphatase, lysosomal lipase, cathepsin D and L, leucine aminopeptidase and alanine aminopeptidase activity, while pyridoxine - β-glucuronidase, β-galactosidase, N-acetyl-β-glucosaminidase, acid phosphatase, leucine aminopeptidase and alanine aminopeptidase. Vitamins B₁, B₂ and B₆ only decreased lysosomal esterase activity in the kidney. In comparison with the liver, the kidney revealed the greater reactivity of the studied lysosomal enzymes.

The experiment was conducted on the influence of testosterone on the activity of ten lysosomal enzymes in the mouse liver and kidney. Mice were divided into two feeding group [control 16% protein] and [10% protein] in diet. The animals of the both groups were injected with 0.05 mg/kg b.w. of testosterone intraperitoneally. In the lysosomal fraction of the liver and kidney the activity of lysosomal enzymes were estimated. Testosterone decreased activity of all investigated enzymes in the liver, except alanine aminopeptidase, cathepsins D and L, lysosomal lipase. In the lysosomal fraction of the kidney testosterone decreased of all lysosomal enzymes, too, except alanine aminopeptidase. The results suggest that exogenous testosterone and different proteins diet had a significant influence on the activity of investigated lysosomal enzymes.
