호염기성 V. vulnificus는 연안에 존재하는 미생물로서 치명적인 상처 감염과 생명을 위협하는 패혈증과 관련이 있다. Hemolysin은 V. vulnificus를 포함하는 여러 가지 세균종에 의해 생성되는 독성 물질이다. 본 연구에서는 해양 V. vulnificus에서 hemolysin을 정제한 후 hemolysin의 활성에 미치는 pH, 온도 및 금속 이온의 영향을 조사하였다. Hemolysin은 sheep red blood cell을 용혈시켰으며 hemolysin의 최적 pH는 8.0, 최적 온도는 4$0^{\circ}C$이었으며 $K^+$ 이온은 homolysin의 활성을 증가시켰으나 $Mn^{2+}$는 감소시켰다. 그러나 hemolysin은 열에 불안정하였다.

Recently, the horse racing industry in Korea has developed rapidly with good betting turnover. One of the most important factors in enhancing the performance of racehorses is the study of equine exercise physiology. This study was performed to analyze the results of pre-race blood test on race day and evaluate its correlation with the race performance in Thoroughbred racehorses. Twenty-one, healthy 3- to 6-year-old Thoroughbred horses were used to collect blood samples and hematological and biochemical measurements were performed. Results were analyzed to identify its correlation with racing performance. Analysis of hematological profile of pre-race blood of the racehorses revealed that red blood cell indices including RBC, Hb, and PCV levels were elevated. Additionally, levels of AP, AST, and GGT were also elevated in pre-race blood of horses on race day. RBC, Hb, and PCV levels of high performance racehorses were significantly lower than those of low class racehorses. Moreover, the analysis of correlation between blood test results and racing ability-related categories have shown negative correlations for rating, placing strike rate, prize money per race, RBC, Hb, and PCV and positive correlations for G3F and PCV. Additionally, AST value was positively correlated to prize money per race. Thus, the results of this study show that red blood cell indices and AST are good parameters for evaluating racing performance of horses before the race.

In order to investigate sedative action of detomidine and its effect on physical signs, hematological and blood chemical components, 15 Holstein cattle were used. The dosage of detomidine was 25 ${\mu}$g/kg and 50 ${\mu}$g/kg. Blood was collected before injection, 30, 60 and 120 min. after injection. Induction time of sedation in a cattle given with 25 ${\mu}$g/kg and 50 ${\mu}$g/kg of detomidine was 10.6${\pm}$2.8. 7.6${\pm}$1.0min. respectively and maintenance time was 70.4${\pm}$8.3, 86.5${\pm}$9.9, respectively. After injection of detomidine, body temperature was slightly increased, heart rate and respiratory rate were slightly decreased. The levels of red blood cell, hemoglobin, packed cell volume and white blood cell were not changed by detomidine. Blood glucose level following detomidine was markedly increased but total protein, serum glutamic oxaloacetic transminase, alkaline phosphatase, lactic dehydrogenase, blood urea nitrogen and creatinine were not changed. This results indicated that detomidine was useful sedative in bovine practice.

Objectives : To investigate the effects of Cornu cervi parvum pharmacopuncture with regard to the blood picture and antioxidative activity in rats. Methods : Sprague-Dawley rats were divided into 3 groups (n=5 each) and were treated with Cornu cervi parvum pharmacopuncture every other day for 2 weeks. The groups are classified as follows; normal control without treatment (control group), Cornu cervi parvum pharmacopuncture at CV4 (CV4 group), and Cornu cervi parvum pharmacopuncture at BL23 (BL23 group). Thereafter, the blood and liver samples were obtained for blood analysis and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activity measurement. Results : Cornu cervi parvum pharmacopuncture groups showed higher values of red blood cell count and plasma cell volume compared with those of the control (p<0.05). However, hemoglobin level showed no significant differences among groups. With regard to the blood picture, plasma concentration in total protein and albumin showed no significant differences in pharmacopuncture groups, while higher ratio of albumin/globulin was observed in CV4 group. White blood cell counts and its composition showed no significant differences among groups. Pharmacopuncture groups showed higher values in SOD, CAT, and GSH-Px activities compared with those of control group. Conclusions : Cornu cervi parvum pharmacopuncture alleviates oxidative activities in rats.

We have previously shown that gossypol injection into the stroma of testis was found to effectively inhibit the process of spermatogenesis. In this study, properties and chemistry of blood were investigated weekly in ICR mouse after the injection of gossypol into the testicular stroma(5, 10 or 15mg per kg body weight). There were no significant differences in red blood cell(RBC), hematocrit, white blood cell(WBC), basophils, eosinophils and monocytes during first 4 weeks after injection of gossypol between treatments, but neutrophils increased and lymphocytes decreased, respectively(P<0.05). Total content of protein, albumin and globulin were not different, compared with control. However, the concentration of glucose after injection of gossypol increased significantly(P<0.05). In conculsion, the results of this study indicated that injection of gossypol into stroma of testis might affect both properties and chemistry of blood in mice.

The effect of red ginseng ethanol extract on the immunotoxicity of diethylstilbestrol (DES) was studied in ICR mice. ICR male mice were divided into S groups (10 mice/group), and red ginseng ethanol extract (50, 100 and 200 mg/kg body wt., respectively) and DES (1 mg/kg body wt.) were injected intraperitoneally (i.p.) to ICR mice once a day for 2 weeks. Mice were sensitized and challenged with sheep red blood cells (S-RBC). Immune response were evaluated by humoral immunity, cell-mediated immunity, non-specific immunity, and circulating leukocyte counts. The results of this study were summarized as followings: 1. The DES-treated control group as compared with normal group showed the tendency to decrease body weight rate and relative liver weight, decreased both humoral and cellular immune responses, phagocyte activity, and circulating leukocyte counts, but increased the natural killer (NK) cell activity. 2. Compared with the DES-treated control group, DES plus red ginseng ethanol extract-treated groups significantly decreased the body weight rate (P<0.01). Relative liver weight was significantly decreased in DES plus red ginseng ethanol extract (50mg/kg)-treated group (P<0.01), but significantly increased in DES plus red ginseng ethanol extract (100mg/kg)-treated group (P<0.01). Relative spleen and thymus weights were significantly enhanced in DES plus red ginseng ethanol extract (100 mg/kg)-treated group (P<0.01), but significantly decreased in DES plus red ginseng ethanol extract (200 mg/kg)-treated group (P<0.01). 3. Both humoral and cellular immune responses were significantly decreased in DES plus red ginseng ethanol extract-treated groups rather than in the DES-treated control group (P<0.01). Especially, it weakened the decrease in DES plus red ginseng ethanol extract (100 mg/kg)-treated group. 4. Phagocyte activity and circulating leukocyte counts were significantly decreased in DES plus red ginseng ethanol extract-treated groups rather than in the DES-treated control group (P<0.01). Especially, it weakened the decrease in DES plus red ginseng ethanol extract (100 mg/kg)-treated group. NK cell activity was significantly enhanced in DES plus red ginseng ethanol extract (100 mg/kg)-treated group (P<0.01), but significantly decreased in DES plus red ginseng ethanol extract (50 and 200 mg/kg)-treated groups (P<0.01).
