The results show that the degree of spheroidization and the amount of massive carbides increase progressively as a function of the treating cycles.
Higher solution treating temperature led to correspondingly higher charging efficiency, accumulation rate and hydrogen uptake efficiency, however, charging efficiency and hydrogen uptake efficiency reduced inevitably after several hydrogenation-solution treating cycles due to saturation.
In the oestrous cycle following the saline treated cycle, another mare developed a spontaneously prolonged luteal phase.
Although all of the mares had shown normal cycle lengths prior to the study, one mare (mare Me) developed a prolonged luteal phase in the first cycle studied and also, in the subsequent, saline treated, cycle.
Among the control mares, 25%% (1/4) developed a spontaneously prolonged luteal phase in the saline treated cycle (this mare showed prolonged luteal activity twice during the study; see results).
Ovulation data were collected from 27 control cycles and 26 treated cycles.
Interestingly, a greater number (P=0.017) of treated cycles (5/26) resulted in follicular regression than did control cycles (0/27).
Corpus luteum (CL) diameter, progesterone concentration, and follicular dynamics characteristics were compared between control and treated cycles.
The interovulatory interval of treated cycles (19.7 ± 2.4 days) was not different (P > 0.05) from that of controls (23.8 ± 0.9 days).
Buserelin treatment induced a rise in LH concentration during the 48 h period of the experiment, and LH concentrations before ovulation were significantly higher in buserelin treated cycles than in placebo cycles.
Table 3 summarises the number of patients treated, cycles administered and DLTs per dose level.
