Gonadotropin-releasing hormone-stimulated sperm binding to the human zona is mediated by a calcium influx.
Morales P, Pizarro E, Kong M, Kerr B, Ceric F, Vigil P. Morales P, et al. Biol Reprod. 2000 Aug;63(2):635-42. doi: 10.1095/biolreprod63.2.635. Biol Reprod. 2000. PMID: 10906075
We tested whether GnRH increases sperm-zona binding in Ca(2+)-free medium and in the presence of Ca(2+) channel antagonists. We also examined the GnRH effect on the intracellular free Ca(2+) concentration ([Ca(2+)](i)). ...The GnRH-induced increase in [Ca(2+)](i) was fast …

[Calcium-dependent chloride channels in plasma membrane of oocytes from toad, Bufo bufo gargarizans].
Pi YL, Ma JH, Zhang PH, Duan JJ. Pi YL, et al. Sheng Li Xue Bao. 2006 Oct 25;58(5):471-6. Sheng Li Xue Bao. 2006. PMID: 17041732 Free article. Chinese.
It was found that a sustained outward current was elicited by depolarization. Potassium channel blockers (tetraethylammonium chloride, TEA, 10 mmol/L and 4-aminopyridine, 4-AP, 10 mmol/L) reduced the outward current to (23.4+/-0.72)% of the maximum. However, further …

Mechanisms mediating cholinergic antral circular smooth muscle contraction in rats.
Wrzos HF, Tandon T, Ouyang A. Wrzos HF, et al. World J Gastroenterol. 2004 Nov 15;10(22):3292-8. doi: 10.3748/wjg.v10.i22.3292. World J Gastroenterol. 2004. PMID: 15484303 Free PMC article.
Lack of calcium as well as the presence of the L-type calcium channel blocker, nifedipine, also inhibited the cholinergic contraction, with a reduction in response from 2.5+/-0.4 g/mm2 to 1.2+/-0.4 g/mm(2) (P<0.05). ...

Absorption, distribution and excretion of nilvadipine, a new dihydropyridine calcium antagonist, in rats and dogs.
Tokuma Y, Fujiwara T, Noguchi H. Tokuma Y, et al. Xenobiotica. 1987 Nov;17(11):1341-9. doi: 10.3109/00498258709047164. Xenobiotica. 1987. PMID: 3433803
The ratios of unchanged drug to radioactivity in plasma after oral dosing were 0.4-3.5% in rats and 10.4-22.6% in dogs. The half-lives of radioactivity in plasma after i.v. and oral dosing were similar, i.e. 8-10 h in rats, estimated from 2 to 24 h after dosing and 1.5 d i …
