The present experiment was performed in order to know the therapeutic effect of laserpuncture and aquapuncture with methionine on recovery in artificially induced hepatic damaged rats by carbon tetrachloride. The animals were divided into control, laserpuncture and aquapuncture groups. The changes of serum enzyme activities(ALT and AST), serum total protein contents, protein fractions(ALB and GLB) and A/G ratio were examined before and after application of laserpuncture and aquapuncture. In change of serum ALT activity, recovery with treatment in laser and aquapuncture groups was more rapid than that of control. The significant decreased value was shown on 3rd(P < 0.05) and 7th day(P < 0.01) after treatment in laserpuncture group and on 7th day(P < 0.05) after treatment in aquapuncture group. In addition, significance was detected on 2nd day(P < 0.05) between laserpuncture and aquapuncture groups. In change of serum AST activity, recovery with treatment in laserpuncture and aquapuncture groups was more rapid than that of control. The significant lower values on 7th day(P<0.01) in aquapuncture groups. In addition, significant low value was detected on 7th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture group. The change of serum TP contents showed similar pattern in control, laser and aquapuncture groups. The significances were detected on 7th day(P < 0.05) in both experimental groups. In addition, significant high value was detected on 2nd day(P < 0.05) in laserpuncture group comparing with that of aquapuncture group. The change of serum ALB content with treatment in laser and aquapuncture groups was more rapid than that of control. The significant high value was shown on 2nd(P < 0.01), 5th(P < 0.05) and on 7th day(P < 0.01) in laserpuncture group. In addition, significant high value was detected on 3rd day(P<0.01) only in aquapuncture group comparing with laserpuncture group. The change of serum GLB content showed similar pattern among groups. The significant low values were detected on 2nd day(P < 0.05) in aquapuncture group. In addition significant high value was detected on 5th day(P < 0.01) only in laserpuncture group comparing with that of aquapuncture group. In change of A/G ratio laser and aquapuncture groups showed higher values than that of control. The significant high values were detected on 1st day(P < 0.Of) and 2nd day(P < 0.05) in laserpuncture group, and on 1st day(P < 0.05) and 2nd day(P < 0.01) in aquapuncture group. In addition, significant high value was detected on 5th day(P < 0.05) in aquapuncture group comparing with that of laserpuncture. Considering above findings collectively, it was considered that both laserpuncture and aquapuncture were effective; aquapuncture was more effective than laserpuncture for recovery of hepatic damage.

Ovaries from total 192 slaughtered cows(154 Korean native cows and 38 Holstein cows) were collected during the slaughtering process in Kimhae, Changyoung and Yangsan abattoirs in Kyungnam province from January 2001 to January 2002. In order to investigate incidence of the ovarian cysts, anatomical, histological observations were performed and also TUNEL methods and PCNA antibody by immunogistochemical methods for diagnostic accuracy of cysts in a few ovaries were applied. Apoptotic positive cells by TUNEL method appeared not or a few in cystic walls but appeared more number in normal large follicular walls and the proliferative positive cells by PCNA antibody appeared numerous in normal large follicular walls but not or a few in cystic walls. The incident rates of ovarian cysts were 19.5% in Korean native cows and 18.4% in Holstein cows. The incident rates of ovarian cysts in Holstein cows were lower than that of Koran native cows. The incident rates of follicular cysts and luteal cysts in Korean native cows were 11.7% and 7.8% respectively. The incident rates of follicular cysts and luteal cysts in Holstein cows were 10.5% and 7.9%, respectively. Higher incidence proportions of ovarian cysts according to seasons in Korean native cows were ordered as spring (29.8%), autumn (21.4%) winter (14.3%) and summer (6.7%). Rates of cows with single cyst and multiple cysts were 63.3%(19 heads /30 heads) and 36.7%(11 heads/30 heads) in 30 cystic Korean native cows, respectively. Cystic cows with corpus luteums were 50.0%(15 heads) in 30 Korean native cows and 42.9%(3 heads) in 7 dairy cows, respectively. Among 15 cystic Korean native cows with corpus luteums, rates of cows with single corpus luteum were 66.7%(10 heads) and rates of multiple corpus luteum were 33.3%(5 heads ), respectively. The average diameter of cysts and corpus luteums in cystic ovaries were 21.0$\times$17.1 mm and 18.1$\times$13.8 mm in 30 Korean native cows and 20.6$\times$17.7 mm and 19.3 $\times$ 14.9 mm in 7 Holstein cows, respectively. So the average sizes of cysts in cystic ovaries were larger than those of corpus luteums.

Ovaries from total 192 slaughtered cows, 154 Korean native cows and 38 dairy cows were collected during the slaughtering process in Kimhae, Changyoung and Yangsan abattoirs in Kyungnam province from January 2001 to January 2002. Rates of pregnant and non-pregnant and ovarian findings were invested. Rates of pregnant cows in 192 slaughtered cows were 12.5% (24 cows) and in difference of cow breeds, 11.0% (17 cows) in 154 Korean native cows and 18.4% (7 cows) in 38 dairy cows from total 192 cows, respectively. Ages of fetuses in pregnant Korean native cows were mostly less than 4 months and ages of fetuses in dairy cows were mostly about 7-8 months. Cows which each diameter of follicles and corpus luteums in same cow was more than 5-6 mm in diameter were 69.8% (134 cows) in total 192 slaughtered cows and in difference of cow breeds, 64.7% (11 cows) in 17 Korean native cows and 57.1% (4 cows) in 7 dairy cows. Mean diameter of foliicles and corpus luteums in Korean native cows are 13.7$\pm$5.6$\times$ 11.2$\pm$4.6mm and 17.5$\pm$4.6$\times$14.6$\pm$4.0 mm in non-pregnat cows, and are 11.0$\pm$4.8$\times$9.1 $\pm$ 2.6mm and 21.2$\pm$2.9$\times$18.3$\pm$ 2.7 mm in pregnant cows, respectively. Mean diameter of follicles and corpus luteums in dairy cows are 15.8$\pm$7.1 $\times$ 14.3$\pm$ 6.0 mm and 20.3$\pm$5.9$\times$16.9$\pm$ 5.8 mm in non-pregnant cows, and are 10.1 $\pm$ 3.0$\times$9.2$\pm$2.3 mm and 23.0$\pm$ 1.7$\times$20.1 $\pm$ 1.3 mm in pregnant cows, respectivley. The above findings indicate that the co-appearance rate of follicles and corpus luteums in same cows are higher in both pregnant and non-pregnant cows. Compared in pregnant and non-pregnant cow ovaries, mean size of follicles are smaller in pregnant cows but size of corpus luteums are more larger in pregnant cows than in non-pregnant cows. Correlation of the follicle size (Y) and corpus luteum size (X) in same cows developed each other in inversive size. Those correlative formulas appeared to be Y = -0.2022X+17.175 in Korean native cows and Y= -0.5754 X+24.153 in dairy cows.

The effect of beta-glucan ($Polycan^{TM}$) derived from Aureobasidium pullulans SM-2001 were observed on, collagen-induced rheumatoid arthritis (RA) in DBA mice. Six week-old male DBA/1J mice were immunized by the intradermal injection of $200\;{\mu}g$ of bovine type II collagen with the equal volume of complete Freund's adjuvant at the tail base on day 1. On day 21, the mice were boosted by the intradermal injection of $200\;{\mu}g$ of bovine type II collagen with incomplete Freund's adjuvant. From the first immunization, mice had been administered $Polycan^{TM}$ (21.25, 42.5 and 85 mg/kg), diclofenac and vehicle once a day for 4 weeks, respectively. Collagen-induced hyperimmunities and arthritis signs were markedly and dose-dependently inhibited by treatment of $Polycan^{TM}$ compared with RA control except for tibial cartilages of $Polycan^{TM}$ 21.25 group. $Polycan^{TM}$ effectively inhibited the histopathological changes of collagen-induced arthritis and hyper-immunities.

To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone concentration, rectal palpation and ultrasonography for measuring the cystic wall thickness and diameter of cyst and corpus luteum were investigated from 1,188 dairy cows with ovarian cysts. The plasma progesterone concentrations were 0.3$\pm$0.4 (mean$\pm$SD) ng/ml in 629 cows with follicular cysts, 3.7$\pm$1.1 ng/ml in 431 cows with luteal cysts, and 3.8$\pm$1.2 ng/ml in 128 cows with coexist of ovarian cysts and corpus luteum, respectively. The cystic wall thickness by ultrasonography were 1.6$\pm$0.4 mm in 629 cows with follicular cysts, 4.2$\pm$1.5 mm in 431 cows with luteal cysts, and 1.6$\pm$0.6 mm in 128 cows with coexist of ovarian cysts and corpus luteum, respectively. The days from initial treatment to insemination in follicular cysts were 28.1$\pm$6.9 days in treatment of GnRH alone, 15.9$\pm$2.9 days in combination of GnRH and dinoprost, and 15.1$\pm$3.1 days in combination of GnRH and cloprostenol. The percentages of cows conceived within 100 days after initial treatment were 61 %, 68% and 73% in treatment of GnRH alone, combination of GnRH and dinoprost, and combination of GnRH and cloprostenol, respectively. The days from initial treatment to insemination in luteal cysts were 3.8$\pm$0.6 days in treatment of dinoprost alone and 3.8$\pm$0.7 in cloprostenol alone. The percentages of cows conceived within 100 days after initial treatment were 69.5% and 68.5% in treatment of dinoprost and cloprostenol, respectively. The days from initial treatment to insemination in coexist of cysts and corpus luteum were 3.7$\pm$0.7 days in treatment of dinoprost alone and 3.8$\pm$0.6 in cloprostenol alone. The percentages of cows conceived within 100 days after initial treatment were 87% and 84% in treatment of dinoprost and cloprostenol, respectively. These results suggest that the best choice for treatment agents in ovarian cysts were combination of GnRH and PGF$_2$$\alpha$ in follicular cysts, and the PGF$_2$$\alpha$ in luteal cysts and in coexist of cysts and corpus luteum, respectively. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosis and selection of treatment remedy in cystic ovaries of bovine.

This study was carried out to investigate the effects of the Korean Safflower (Carthamus inctorius L) seed powder on serum level of hormones and trabecula area during the recovery from osteoporosis induced ovariectomized rats. Four month-old rats were ovariectomized (OVX), remained untreated for 8 weeks, and were subsequently administered safflower seed (0.03 g/kg) every other day 30 for days. We examined the effects of treated safflower seed every 10 days on ovariectomy-related changes in Insulin-like Growth Factors, Insulin-like Growth Factor binding protein-3 (IGFBP-3), Estrogen, Bone-specific alkaline phosphotase, Calcium, and Phospotase in the serum, and also histomorphology of the proximal fibula metaphysis and femur/body weight rate. Ten and 20 days after safflower seed treatment in OVX rats, serum levels of IGF-I, -II and IGFBP-3 were not different from the Sham and OVX groups. In 30 days, serum levels of IGF-I,-II and IGFBP-3 were higher after safflower seed treatment in OVX rats as compared to the other two groups (p<0.05). Bone alkaline phosphatase levels were increased through safflower seed treatment in OVX rats compared to the other two groups in 30 days. There were no differences between OVX and safflower seed treated OVX rats in serum levels of estrogen and femur/body weight rate, but estrogen levels for the sham group were higher than for the other two groups. The safflower seed is increased to serum levels of IGFs, IGFBP-3 and BALP of osteoporosis induced by ovariectomized rats. Thus, we conclude that the safflower seed is a possible role for improvement of osteoporosis induced-ovariectomized rats.

The immunoenhancing effect of CLA isomers (CLA mixture, 10t-12c CLA, 9c-11c CLA, 9c-11c CLA, and 9t-11t CLA) on phagocytic activity of porcine peripheral blood leukocytes was examined. The phagocytic activities of peripheral blood mononuclear cells (PBMC) and polymorphonuclear cells (PMN) were analyzed by a flow cytometry system. The direct treatments of CLA isomers have no effect on phagocytosis of PMN as well as PBMC composed of approximately 10% monocytes and 90% lymphocytes. However, the phagocytic activities of PMN and monocyterich fraction from PBMC were remarkably enhanced by culture supernatant from PBMC treated with CLA mixture, 10t-12c CLA and 9c-11t CLA but not 9c-11c CLA and 9t-11t CLA. The phagocytic activity of PBMC was not enhanced by culture supernatant from PBMC treated with all CLA isomers. These results indicated that CLA isomers such as CLA mixture, l0t -12c CLA and 9c-11t CLA have an enhancing effect on phagocytosis of PMN and monocytes, which may be mediated through active humoral substances produced by CLA-stimulated PBMC. This study suggested that CLA stimulates PBMC to elaborate soluble factor(s), which may be an important mechanism for the enhancement of phagocytosis in non-specific immunity.

A 5-year-old Rottweiler neutered female dog was presented with signs of mandibular and popliteal lymphadenopathy, erosion in mucocutaneous junction of muzzle and lips, multiple papules and nodules in right rear limb and neck, and alopecia in right thorax. There was no further clinical sign except anorexia, sporadic fever and ocular hyperemia. She hadn't shown any response to carprofen prescribed by local veterinarian. Hematological abnormalities included mild anemia and severe lymphocytosis. On serum biochemical profile, only elevated AST level was noticed. On cytological examination, there was an evidence of mild bacterial infection which seemed to occur secondarily. Three sites were biopsied that included muzzle, upper lip and right thoracic region. Histopathologically, multifocal confluent pyogranulomatous dermatitis, scattered granulomatous inflammation in subcutis and severe septal panniculitis were observed. Special stainings(Gram, Acid-fast, PAS, Giemsa) were performed to reveal that a dog was negative for any organism. Finally, sterile pyogranuloma/granuloma syndrome (SPGS) was diagnosed. The treatment was initiated with predinsolone and enrofloxacin. The condition was successfully resolved after 4 weeks of treatment. This good response suggests that SPGS may be immune-mediated disease of its pathogenesis and this drug combination may be a viable therapeutic option for dogs suffering from SPGS. Also, this article reports a case of SPGS in Rottweiller for the first time.

This study was carried out to monitor the response of ovaries and cyst according to treatment with GnRH or combination of GnRH and $PGF_2{\alpha}$ in dairy cows with ovarian follicular cysts. Thirty cows were diagnosed as having follicular cysts by rectal palpation, ultrasonography and progesterone (P4) assays. Ten cows were treated with GnRH (control), and the other twenty were treated with $PGF_2{\alpha}$ at 10 days after GnRH treatment. All the animals were re-examined by ultrasonography and blood was collected for the measurement of plasma P4 concentration at day 0 (the day of treatment), day 7, day 10, day 13, day 24 and day 34, respectively. In 30 cows that were diagnosed with follicular cysts, mean plasma P 4 concentrations on day -II and day -I were 0.3 ng/ml and 0.4 ng/ml. On day 10 increased as 2.7$\pm$0.2 ng/ml. Mean cystic wall thickness by ultrasonography on day -11 and day -I were 2.1 mm and 2.2 mm. In 9 cows responded on luteinization of cystic wall, cystic wall thickness was 3.9$\pm$0.5 mm at day 10 after GnRH treatment. The responses of ovaries until day 10 after GnRH treatment included development of corpus luteum in the ovary bearing the cyst or in the contralateral ovary (12 cows), luteinization of cystic wall (6 cows) and clouding of the anechoic antrum of cysts (2 cows). The ovarian responses according to the combination of GnRH and $PGF_2{\alpha}$ included regression of the corpus luteum (12 cows), increase (1 cow) and no change (1 cow) of cyst size until last examination, and complete disappearance on day 13 (6 cows), 23 (6 cows) and 34 (4 cows). Combination treatment group of GnRH and $PGF_2{\alpha}$ showed a higher pregnancy rate within 100 days after initial treatment (40.0 vs 65.0%) and shorter intervals from the treatment to conception (45.4$\pm$25.8 vs 53.5$\pm$31.4 days) compared with control. It was concluded that the administration of $PGF_2{\alpha}$ following GnRH treatment is effective in shortening the interval from treatment to conception in cows with follicular cyst. Also, this study suggested that the response of the cyst according to treatment revealed various types. Therefore, veterinarians should pay attention to monitor of the response of cystic ovaries after treatment, specially no change, slowly decrease or increasement of cyst size after treatment.

The natural herbal antimicrobial additive, Flavo-$SK^{TM}$, was developed by Zoonosis Research Center of Wonkwang University. The purpose of this study was to evaluate the effects of Flavo-$SK^{TM}$ on the health status and performance of growing chickens. This study was conducted on the growing chickens (n=20,000) for 31 days in a growing chickens husbandry. The animals were divided with two groups; Flavo-$SK^{TM}$ treated group (n=10,000) and commercial diet feeding group (n=10,000). The Flavo-$SK^{TM}$ treated animals had provided with commercial diet adding the Flavo-$SK^{TM}$ as 0.29%. During the study period, we compared clinical signs, weight increase rate, diet consumption amount, gross finding, necropsy findings and histopathological findings between the treated group and non treated group. As the results of this clinical trial, the natural herbal antimicrobial additive, Flavo-$SK^{TM}$, showed the effects on disease reduction. It is suggested that Flavo-$SK^{TM}$ has the antimicrobial effects.
