② The biochemical analysis of alpaca seminal plasma were:0.116±0.024mg/dl for copper, 1.346±0.123mg/dl for zinc,2.383±0.494mg/dl for iron,3.78±0.30g/dl for total protein, 4.62±0.28mg/dl for Citric acid and 5.64±0.27mg/dl for fructose.
Total sperm counts was decreased from 355. 34 × 106(1984) to 262. 26 × 106 (1996)and the mean seminal volume was decreased from 3.31 ml (1981) to 2. 97 ml (1996),both tending to decline but not being statistically significant (P＞0. 05).
The values of seminal fructose were 23 22±20 64mg/dl and 274 2±126 7mg/dl,pH values were 6 48±0 18 and 7 2±0 19,semen volumes were 0 72±0 47ml and 2 95±23 64ml respectively.
The average velocity of rapidly moving sperms (VRM) and the Na~+, K~+, Ca~(++), Mg~(++), Cu, Fe, Zn, Mn of seminal plasma were measured in 17 fertile and 30 asthenozoospermic semen samples.
Add 0,5,10,25,50 and 100 ng/mL platelet-activating factor (PAF) into the artificially gathered seminal fluid of Changbai pig and breed them in 37℃ thermostatical water for 5,15,25,35,45 and 60 minutes.
There was a significant difference of the levels of the IgM between the seminal fluid with WBC and the seminal fluid without WBC(P<0.05),as well as between the positive AsAb and the negative AsAb in the seminar plasma(P<0.01).
The results showed that the positive rate in female pathological specimen, seminal fluid and urine of their sexual partner's were 57. 6% ,57.6% and 18. 1% for HPV16 and 30. 3%,12. 1 % and 3. 0% for HPV18 respectively.
The positive rate of interferon level in seminal samples of normal fertility is 18.18%, Whereas in seminal fluid of 83 infertile men the positive rate of interferon level is 55.42%, significant difference was found between them(P<0.01).
Studies on steritity due to abnormal seminal fluid as a result of chronic prostatitis and epididymitis in 103 cases were treated by self—formulated Qingjing De-coction with a cured rate of 77.7%,among whom 42cases were pregnant,the rate of pregnancy being 40.8% and the total effective rate,90. 3%.
Studies of artificial insemination of cranes and cryoconservation of their semen have been carried out in the nursery of rare species at the Oka Biosphere Reserve for many years.
An experiment is described on artificial insemination of females of the white-naped crane Grus vipio by the frozen-thawed semen of the Siberian white crane G.
When trypsin reacts with Herring sperm DNA (hsDNA), Salmon sperm DNA (sDNA), and Calf thymus DNA (ctDNA) to form a complex, the resonance Rayleigh scattering (RRS) was remarkably enhanced and new RRS spectra appear.
Structural and parameterized models for generalized description of the images of normal and pathologically changed cells of blood and sperm were presented by way of example.
The results show that quantitative and morphohistological trends in the development of sperm cells and Sertoli cells in both lines are similar in both lines.
According to results obtained, L-PGDS may have the ability to improve progressive motility of sperm, and L-PGDS in seminal plasma and on sperm surface may impact male fertility in the female reproductive tract.
Andrologic investigations comprised a study sexual history, physical examination of the external sexual organs, examination of the seminal fluid and in a few cases biopsy of testes material.
In contrast to ?-lactam antibiotics their concentrations in prostatic fluid, in prostatic tissue and in seminal fluid are relatively high in comparison to the corresponding plasma concentrations.
