TLDR
Analysis of the chemical constituents of the fluid from the first three segments showed that the concentration of sodium, bicarbonate, inorganic phosphate, proteins and lactic acid increased significantly from the fimbriated end to the utero-tubal junction, while chloride concentration decreased significantly.Abstract:
Forty-six, mature, New Zealand white does were used for collection of fluid from the Fallopian tubes. Ligation of the tubes into four isolated segments was carried out with minimal disturbance to the blood supply, using an operating microscope. The volume of fluid collected decreased from the fimbriated end to the utero-tubal junction. Analysis of the chemical constituents of the fluid from the first three segments showed that the concentration of sodium, bicarbonate, inorganic phosphate, proteins and lactic acid increased significantly from the fimbriated end to the utero-tubal junction, while chloride concentration decreased significantly. These results support the possibility that the different segments of the oviduct may play specific roles in early events of reproduction.read more

Taurine, hypotaurine, epinephrine and albumin inhibit lipid peroxidation in rabbit spermatozoa and protect against loss of motility.

TL;DR: Hypotaurine reduces the amount of rate of superoxide production, as measured by the rate of reduction of acetylated ferricytochrome c by O(2), from rabbit sperm under these conditions and concomitantly reduces inactivation of the superoxide dismutase in these cells.

Spontaneous lipid peroxidation in rabbit epididymal spermatozoa: its effect on sperm motility.
Juan G. Alvarez,Bayard T. Storey +1 more
TL;DR: A strong dependence of rabbit sperm peroxidation on ionic composition of the medium is suggested to involve perturbation of the equilibrium between O2 .- and its conjugate acid species being the agent ofperoxidation.

The elemental composition of the environments of the gametes and preimplantation embryo during the initiation of pregnancy.
TL;DR: Electron probe microanalysis and elemental analyses of the liquid ejaculate and proestrous uterine fluid demonstrate that the liquid semen is the main modifier of prostrous uterusine fluid in the formation of postcoital uterine fluids.

Concentrations of energy substrates in oviductal fluid and blood plasma of pigs during the peri-ovulatory period.
TL;DR: Large White gilts, 9 to 18 months old, that had exhibited at least two natural oestrous cycles were divided into three groups (phases) and lactate in the ampulla of mated animals was higher than in the pre-ovulatory group and glucose concentrations were significantly higher in blood plasma than in oviductal fluid.

An instrument and method for automatic, rapid, accurate, and sensitive titration of chloride in biologic samples.
TL;DR: An instrument and method are described which provide accurate, rapid, and automatic analysis of chloride in biologic samples, by electrometric titration with silver ion, which is sensitive, measuring accurately as little as 0.25 μEq of chloride.
