Summary: Gamacide 20 in 10 mg/l and 20 mg/l concentrations causes
morphological and cyto-histological changes by H.vulgaris Pallas (Cnidaria)
immediately after treatment. Considerable damage ofintra cellular membranes
was observed, espacially in a higher concentration. Intracellular digestion
of treated hydras lasted longer then in the control. The number of buds in
hydras treated with 10 mg/l Gamacide 20 was distinctly larger then in the
control.
Keywords: Gamacide 20, hydras, treatment, cyto-histological, zymogen cells

Summary: Within 24 h time, Torak EC 24 in 10 mg/l and 30 mg/l
concentrations causes the worst damage immediately after treatment. In the
treated hydras, a considerable state of contraction, a damage of tentacles
and the hypostome as well as adamage of intracellular membranes and
cellular organelles was observed. Besides, during the experiment, the
treated hydras in both concentrations used were budding more intensely than
the control.

Summary: Investigations showed that the tree insecticides used had
the most damaging effect upon hydra immediately after treatment.
Thetentacles and the hypostome are the parts most often damaged.Inside the
affected cells lesions appear in the intracellular membranes, the nucleus
shell and the membranes of the mitochondria, Golgi complex and the
endoplasmic reticulum, while the cell membrane is preserved. The damaged
parts of the body regenerate within tree days. Zymogen cells play a
significant role in the course of regeneration. They dedifferentiate into
gastrodermal interstitial cells and later into other types of cells of the
ectoderm and the gastroderm. Apart from their intense participation in
regeneration, these totipotent cells also invariably participate in the
formation of new hydra buds. It was observed that Dimiline WP 25 and Torak
EC 24 in the concentrations used stimulate asexual reproduction of this
animal.
Keywords: Differentiation, dedifferentiation, regeneration, zymogen cells, gastrodermal interstitial cells

Summary: The effect of Gamacide 20 and UV irradiation as well as
their combined effect on green hydra (Hydra viridissima Pallas) was
examined. In the treated hydras a considerable state of contraction and
damage of tentacles and the hypostome was observed. In the course of
regeneration, malformations occured which were localized most frequently in
the oral region of the animals. During the process of regeneration and
complete recovery of the treated animals zymogen and interstitial cells
played the most important role. By dedifferentiation and subsequent
differentiation they restored the lost and damaged cells of the hydras. All
the treated animals budded more intensely than the controls, and Gamacide
20 proved to be the strongest stimulator of budding.
Keywords: Hydra viridissima Pallas, effects of insecticide and/or UV irradiation, stimulation of reproduction
Title: Regeneration of hypostome and foot of hydras treated with

Summary: The regeneration of hypostome and foot of Hydra vulgaris
Pallas was studied. The animals were cut in the central part of the gastral
region and the cut parts were treated with a water solution of the
insecticide Gamacide 20. In parts of hydras treated with a stronger
solution death rate was as high as 20%. The hypostome and tentacles of the
hydras that survived were damaged and also the cytoligical and histological
structure was considerably changed. The closing of the wounds and the
course of regeneration in the treated hydras was similar as in the control
ones, but immediately after the treatment inhibition of regneration was
noticed. During regeneration zymogen cells played a very important role. By
their dedifferentiation and differentiation they compensated for certain
types of destroyed cells. In the course of regeneration a considerable
number of malformated shapes was found. The cut hydras treated with a
stronger solution of the insectide did not reproduced by 15% more buds than
the control ones.
Keywords: Hydra vulgaris Pallas, Gamacide 20, cytology, histology
Title: Response of green hydra to pirimicarb

Summary: Green hydras were treated with 5 mg/l and 20 mg/l water
solutions of pirimicarb. The results showed that immediately after
treatment pirimicarb used at these concentrations had more serious effects
on hydras (hosts) than on algae (endosymbionts). After a short period of
time, the surviving hydras underwent the process of regeneration and the
normal relationship of symbiosis with algae was restored.
