FIGURE LEGENDS 



Fig. 1. Turtles Nos. 22 and 37 on board the 

 "Zond-5" during flight to the moon. 



Fig. 2. Electrocardiogram of the turtles 

 (Second terminal, tape rate 10 

 mm/sec). 1 - Turtle No. 22 (Test); 

 2 - Turtle No. 47 (control) 



Fig. 3- Intestine. Combined tissue block. 



Intestine diameter and layer thickness 

 diminished, villi shortened in test 

 turtles (Brashe, lens enlargement.) 



Fig. 4. Test turtle intestine. Cells with 

 hyper-chromic nuclei, some of which 

 "drop out" in intestine lumen, are 

 seen in the epithelium crypt (Hema- 

 toxyl i ne-eos i ne. Gom. IV, ob. 40, 

 800 X magnif.) 



Fig. 5« Intestine. Combined tissue block. In 

 test turtles PAS - positive reaction 

 deep in the crypt clearly weakened 

 (Shabadash, lens enlargement.) 



Fig. 6. Testss of turtles on board the "Zond-5". 

 Duct diameter diminished, embryo 

 epithelium thinned, united by cells. 

 Considerable outcrops of brown pig- 

 ment in interstitial tissue (Brashe, 

 Gom. VI, ob. 20, 240 X) 



Fig. 7» Testes of intact turtles. Compare with 

 Fig. 6 (Brashe, Gom. VI, ob 20, 240X) 



Fig. 8. Seminal vesicles of turtles on board 

 the "Zond-5". Sperma tozo ids missing 

 from lumen. (Brashe, GOM. VI, ob. 16, 



115*) 



Fig. 3» Seminal vesicles of intact turtles in 

 the vivarium. Lumens filled with 

 spermatozo i ds. (Brashe, Gom. VI, ob. 

 16, 115X) 



Fig. 10. Liver. Combined tissue block. In 



turtles on board the "Zond-5" the cell 

 size diminished, their cytoplasm is 

 darker and basophilic; the amount of 

 pigment is increased (Hema toxyl i ne- 

 eosine. Gom VI, ob. 40, 47OX) 



Fig. 11. Liver of intact turtles. Glycogen in 

 cells in moderate quantity (Shabadash, 

 Gom. VI, ob. 40, 47OX) 



Fig. 12. Liver of test animals. Glycogen con- 

 tent increased. Compare with Fig. 11. 

 (Shabadash, Gom. VI, ob. 40 47OX] 



Fig. 13. Liver. Combined tissue block. In 



turtles on "Zond-5", no fat in cells. 

 (Scarlet red. Gom. IV, ob. 40, 800x) 



Fig. 14. Liver. Monoam i noox idase activity in 

 turtles on the "Zond-5" reduced (a) 

 and significant (b) in intact animals. 

 (Glenner et al., Gom. VI, ob. 16, 1 1 fjX ) 



Fig. 15. Seminal vesicles of turtles at the 



cosmodrome. Small quantity of sperma- 

 tozoids remain in lumens. (Brashe. 

 Gom. VI, ob. 16, llfjX)
