Title: The effects of Gamacide 20 upon Hydra vulgaris Pallas (Cnidaria)

Authors:
Kalafatić, Mirjana
Žnidarić, Danica (55795)
Lui, Ante (103943)
Journal: Biologia
Number: 3
ISSN: 0006-3088
Volume: 46
Year: 1991
Pages: from 245 to 250
Number of references: 9
Language: engleski
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

Title: Changes in Hydra vulgaris Pallas (Cnidaria) caused by the effect of Torak EC 24 insecticide

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

Title: Combined effect of Gamacide 20 and UV irradiation on green hydra (Hydra viridissima Pallas)

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 Gamacide 20

Authors:
Kalafatić, Mirjana
Journal: Biologia

Language: engleski
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.
Keywords: Green hydra, symbiosis, pesticides, morphological changes, cytological and histological changes, regeneration
