Effects of piscine and mammalian gonadotropins on gametogenesis in the catfish, Heteropneustes fossilis (bloch)
Abstract Salmon (SG-G100) and mammalian (ovine FSH and LH) gonadotropins were tested for their gonadotropic activity in the hypophysectomized catfish, Heteropmeustes fossilis , by evaluatingExpand
Effects of partially purified salmon pituitary gonadotropin on ovarian maintenance, ovulation, and vitellogenesis in the hypophysectomized catfish, Heteropneustes fossilis (Bloch).
TLDR
Salmon pituitary gonadotropin (SG-G100) was tested for its gonadotropic activity in the female catfish by evaluating ovarian maintenance and ovulation, and the induction of oogenesis and vitellogenesis in the regressed ovaries of the hypophysectomized catfish during the preparatory and the postspawning periods. Expand
Effects of salmon pituitary gonadotropin, ovine luteinizing hormone, and testosterone on the testes and seminal vesicles of hypophysectomized catfish, Heteropneustes fossilis (Bloch).
TLDR
The possibility of one functional gonadotropin regulating the whole maturation phenomenon in the male catfish is discussed, and a dose-dependent response in the testes and seminal vesicles is studied. Expand
Ovarian maintenance in the hypophysectomized catfish, Heteropneustes fossilis (Bloch), with mammalian hypophyseal and placental hormones, and gonadal and adrenocortical steroids.
TLDR
Of the two placental gonadotropins, the ovaries were better maintained with HCG than with PMS; between HCG and LH, the former was considerably more effective than the latter. Expand
Response of the pituitary of the catfish, Heteropneustes fossilis (Bloch), to bilateral ovariectomy.
TLDR
Hypophyseal response to bilateral ovariectomy was studied in the catfish during the prespawning and the spawning periods and a dramatic increase in the number of granulated basophils of the castrates was seen and the number decreased thereafter. Expand
Temporal effects of artificial induction of ovulation on the hypothalamo-hypophysial-ovarian system of the catfish, Heteropneustes fossilis (Bloch).
Ovarian recrudescence was advanced bytwo months by subjecting the catfish, Heteropneustes fossilis , to a long photoperiodic treatment (14 h/day) for 6 weeks at 25 °C. The precocious
