The aims of this work were to determine the acrosin activity and to evaluate the structural and functional integrity of AS boar spermatozoa. The acrosin activity of spermatozoa were 5.40, 4.10 and 3.40 mIU/10$^{6}$ sperm in raw, extended and frozen semen respectively , which differed significantly each other (P<0.05). After the raw and extended semen were exposured to cold and thermal shock, the acrosin activities of spermatozoa in the raw semen were 5.39, 5.21 and 5.29 mIU/10$^{6}$ sperm for control (non-shock), cold shock and thermal shock, and those of extended semen were 4.21, 3.98 and 4.00 mIU/10$^{6}$ sperm. This value among treatments did not differ significantly. The acrosin activities of spermatozoa in the extended and stored semen were 3.27, 3.52, 3.46 and 3.23 mIU/10/suup 6/ sperm, while hypo-osmotic test(HOST) values were 56.5%, 64.7%, 66.0% and 56.0%, following 4 days storage at 4$^{\circ}C$, 17$^{\circ}C$ , $25^{\circ}C$ and 37$^{\circ}C$, respectively. The results at 17$^{\circ}C$ and $25^{\circ}C$ appeared to be best compared with the other storage temperatures.

Ethanol consumption causes psychomotor alterations. Hovenia Semen seu Fructus (HS), widely distributed in Korea, China, and Japan, has been reported to have beneficial effects on acute alcohol-induced liver injury. The present study sought to assess the effects of HS extract on ethanol-induced psychomotor alterations in rats. Sprague-Dawley rats were orally (p.o.) given ethanol (4 g/kg) (ethanol group) to induce psychomotor alterations. A separate group (HS-treated groups), were treated with different dosages of HS (50, 100, and 200 mg/kg, p.o.), 30 minutes before ethanol treatment. The control group received only the vehicle (saline). Ethanol-induced psychomotor alterations were evaluated in the open-field, rota-rod, hanging wire, and cold swimming test. In addition, blood ethanol and acetaldehyde concentrations were also measured. Behavioral evaluations and blood analysis were carried out 0.5, 1, 2, 4, and 8 hours after ethanol administration. Pre-treatment of HS ameliorated ethanol-induced alterations in the open-field, rota-rod, and cold swimming test, significantly evident in 2 and 4 hours after ethanol treatment. These improvements coincided with decrease in blood ethanol and acetaldehyde concentration. Based on these results, the present study suggests that HS may have ameliorating effects against ethanol-induced psychomotor alterations.

During the process of freezing, spermatozoa suffer cold shock which increases their susceptibility to lipid peroxidation which plays an important role in ageing of spermatozoa, shortening their life span and affecting the preservation of semen. An experiment was therefore conducted to study the effect of addition of natural antioxidants into semen diluents on the preservability of buffalo semen. Split semen samples were extended in milk egg yolk diluents fortified with vitamin E (MYE), vitamin C (MYC) and control group (MYO); Tris-egg yolk diluents fortified with vitamin E (TYE), vitamin C (TYC) and control group (TYO) and evaluated for their preservabilities at 4-7$^{\circ}C$ and $37^{\circ}C$. Overall least squares mean of percent motility observed after 0, 24, 48, 72 and 96 h of preservation at 4-7$^{\circ}C$ were 66.70, 54.00, 36.80, 21.90 and 12.50, respectively while the estimates for semen extended in MYE, MYC, MYO, TYE, TYC and TYO were 44.80, 42.70, 38.70, 36.00, 35.20 and 33.00 percent, respectively. The results showed that motility was significantly (p<0.01) affected by extender (extender-antioxidant combination) and preservation interval. Overall least squares mean percent motility observed after 0, 4, 8, 12 and 24 h of preservation at $37^{\circ}C$ were 68.50, 58.90, 45.00, 38.10 and 18.10 percent, respectively, while the estimates for semen extended in MYE, MYC, MYO, TYE, TYC and TYO were 48.20, 49.30, 46.80, 45.30, 42.30 and 42.50 percent, respectively. Extender and storage interval were found to be significantly (p<0.01) affecting spermatozoa motility on room temperature preservation. The results indicated that the incorporation of antioxidants, especially vitamin E, had beneficial effect on preservability of buffalo semen.

This study was conducted to develop an intrauterine inseminator (IUI) to deposit of frozen semen into uterus and to evaluate the results obtained after artificial insemination by IUI. Two Japanese spitzs (2 to 4 years of age) were used as semen donors. Semen was collected by manual masturbation into sterile glass collection tubes and separated into 3 fractions with only the sperm-rich fractions retained for further examination. Sperm motility >70%, sperm concentration of 200 to $400{\times}10^6 cells/ml$$\times$g for 5 min and poured out the suspended solution, and then diluted with 2 ml Tris-buffer which was consisted of 2.4 g Tris, 1.4 g citric acid, 0.8 g glucose, 0.1 $\mu\textrm{g}$/ml streptomycin, 100 IU/ml penicillin, 20 ml egg yolk to 100 ml mili-Q water (Ext I) or supplemented with 8 ml glycerol and 1 ml Equex STM paste to 100 rnl (Ext II). The diluted semen was cooled to 5$^{\circ}C$ in cold room, where the temperature in the sample reached 5$^{\circ}C$. Two h after beginning the cooling procedure, 2 ml of Ext II, also at 5$^{\circ}C$, was added and mixed by gently reversing the tubes several times during 1 h. The final sperm concentration for freezing was approximately $50{\times}10^6 cells/ml$. After equilibration, the semen was loaded into 0.5 ml straw and frozen on the liquid nitrogen vapour in styrofoam box. The straws were thawed at 7$0^{\circ}C$ for precisely 6 sec. After thawing of each straw, the frozen semen can survived over 50% motility. All the females were inseminated twice with 1 ml of $25{\times}10^6 cells/ml$

This study was carried out to establish most suitable freezing condition, to evaluate the different glycerol concentration of freezing and thawing rates on motility, viability, membrane integrity and acrosome intecrity of frozen Korean Jeju Black Bull spermatozoa, Semen was collected from a Korean Jeju Black Bull using an artificial vagina and transported to the laboratory. The semen was extended gradually 1:5 then cooled slowly for 2 hrs to 4$^{\circ}C$. The semen was diluted 1:1 with cryoprotectant extenders (3%, 5% and 7% glycerol) and equilibrated for 2 hrs at cold chamber and packed to 0.5 ml straws. The semen straws were located above 3 cm of liquid nitrogen for 5 minutes, above 5 cm for 10 min and above 8 cm for 10 min. And then the frozen straw was plunged into LN$_2$. The presented straws were examined the viability and motility after thawed at 37$^{\circ}C$ water bath. The viability and membrane integrity immediately post-thawing were significantly higher in samples frozen in 7% glycerol than 3% and 5% glycerol (p<0.05). After CTC staining to assess acrosome integrity, F pattern was significantly increased, but B pattern was significantly decreased in 7% glycerol (p<0.05). Freezing distance of 5 cm from liquid nitrogen and pre-cooling for 10 min yield better survival and membrane integrity, but not significant difference. However, AR pattern according to CTC staining was significantly decreased in 3 cm for 5 min.

Fatty acids such as n-3 and n-6 polyunsaturated fatty acids (PUFA) are critical nutrients, used to improve male reproductive performance through modification of fatty acid profile and maintenance of sperm membrane integrity, especially under cold shock or cryopreservation condition. Also, PUFA provide the precursors for prostaglandin synthesis and can modulate the expression patterns of many key enzymes involved in both prostaglandin and steroid metabolism. Many studies carried out on diets supplemented with PUFA have demonstrated their capability to sustain sperm motility, viability and fertility during chilling and freezing as well as improving testis development and spermatogenesis in a variety of livestock species. In addition to the type and quantity of dietary fatty acids, ways of addition of PUFA to diet or semen extender is very crucial as it has different effects on semen quality in male ruminants. Limitation of PUFA added to ruminant ration is due to biohydrogenation by rumen microorganisms, which causes conversion of unsaturated fatty acids to saturated fatty acids, leading to loss of PUFA quantity. Thus, many strategies for protecting PUFA from biohydrogenation in rumen have been developed over the years. This paper reviews four aspects of PUFA in light of previous research including rumen metabolism, biological roles, influence on reproduction, and strategies to use in male ruminants.
