An infertile, three-year-old primiparous cow was diagnosed preliminarily with pyometra by rectal palpation at 180 days postpartum. Ultrasonography showed that the cranial portion of the right uterine horn was distended with fluid, while the base portion of the horn was missing. A dense band of tissue connected the cranial portion of the uterine horn to the uterine body. However, the left uterine horn was normal. Gross postmortem analysis of the reproductive organs confirmed the ultrasonographic observations. Histopathological observations also showed that dark red-brown mucus filled the thin-walled right uterine horn, where neither caruncles nor uterine glands were observed. Finally, this primiparous Holstein cow was diagnosed with segmental aplasia of the right uterine horn.

Reproductive disorders in cows cause economic loss in livestock farms. Reproductive diseases, such as follicular cyst, luteal cyst, endometritis, pyometra, and repeat breeding cause infertility. Among these diseases, endometritis and pyometra are uterine infections that are leading causes of infertility. This study was performed to investigate the causative agents of uterine diseases using bacterial culture. Bacteria were obtained from the reproductive organs (vagina, uterine cervix, and uterine horn) of dairy cow diagnosed with endometritis or pyometra, and cultured on blood agar. The colonies obtained from cultivation for 24 hours were passaged. To identify the bacteria, the colonies grown in passaged culture Gram stained and applied to an automatic biochemical microbial identification system. Escherichia coli were commonly detected in vagina, uterine cervix, and uterine horn of dairy cows diagnosed to pyometra. The cows having endometritis showed not only Escherichia coli but also Pantoea spp. and Klebsiella spp. strains. Dairy cows that were infected with Escherichia coli in uterus caused mastitis or digestive disease. These results suggest that sanitary feeding and management beforehand are needed to prevent bacterial infections.

Background: In recent years, pediatric chronic sinusitis patients who don't respond with antibiotics are increasing, but there are a few reports on the herbal medicine therapy treating pediatric chronic sinusitis, so this report was studied. Objective: To demonstrate the effect of herbal medicine therapy in the chronic sinusitis before and after treatment using computed tomograpy (CT) and plain radiograpy. Materials and methods: Ninty patients (45 mail and 45 femail) treated in our hospital between February 1998 and August 1999 were studied. Ages ranged from 3 to 13 years (mean age :6.5 years). Sixty two patients had a underlyiing family history (allergy or sinusitis of parents or brothers), In the past history, 68 patients had asthma, allergy of milk, atopic dermatitis, bronchiollitis and irritable bowel syndrom. Illness period was from 10 days to 96 months (mean period:12.4 month). Duration of treatment were from 25 days to 200days (mean:96 days). To ascertain the efficacy of treatment, CT in the 42 and plain radiopgrapy in the 48 patients were checked out. In the CT, three images were obtained 2cm interval on the coronal and axial plan. CT findings of the chronic sinusitis were analyzed for mucoperiostal thickening before and after treatment using 4 grades;(normal, mild, moderate, severe). Normal was defined as below 3mm thickening of mucoperiosteum; mild was 3-5mm thickening; moderate was 5mm-1cm thickening; severe was above 1cm thickening. Plain radiograpy using Water's view provided maxillary sinus, anterior ethmoid sinus, frontal sinus. Normal was defined as simillar to density between sinus and oronasal cavity; mild was defined as generally increased density with no significant mucoperiosteal thickning; moderate was partial mucosal thickening without bony hypertropy; severe was total haziness with mucoperiosteal thickening. Gamihyunggyeyungyo-tang was administered mainly. Gamigwaghyangjeungki-san, Gamizwakwi-eum and Gamihyangso-san were administered for through oral route additional symptoms Results: Of the 90 patients, 84 patients showed complete recovery (93%), 4 patients showed no significant interval change(4%) and 2 patients were aggrevated (2%). Sixty patients were severe(67%) and 26 patients were moderate (29%), 4 patients were mild(4%) The duration of treatment was varied with patient conditions (91 days in average); severe were 101.7 days, moderate were 70 days and mild were 63 days. Fifty three patients with maxillary and ethmoid sinusitis were 114 days, 35 patients with maxillary sinusitis only were 71.5 days. Fifty eight patients with both maxillary sinusitis were 94.6 days, 26 patients with either maxillary sinusitis were 65 days. The symtoms of chronic sinusitis were nasal obstruction(75%), cough(69%), purulunt or mucosal discharge(62%), lymphoid follicle(54%), postnasal dripping(49%), headache(23%) and nose bleeding(22%). Conclusion: We know that herbal medicine therapy is the effective treatment of pediatric chronic sinusitis using plain radiograpy and CT. The duration of treatment may be significant assosiation with the location and degree of chronic sinusitis.

This study is conducted to provide a basis for effective management of bad breath with a poll in 155-scaling patients visiting the dental hygiene department of a university located in Gyeong-gi province after grasping the relevance among halitosis, xerostomia, and stress from them. Analysis was performed using PASW Statistics 18.0. The results of the halitosis measurements based on the general properties showed a significant difference in the hydrogen sulfide ($H_2S$) level depending on the patient's age; the highest level of 355.61 was observed in patients in their twenties followed by 227.85 in the fifties (p<0.001). The level was higher in cases with sinusitis or rhinitis (p=0.034). The $H_2S$ and $(CH_3)_2S$ levels showed are levant (r=0.492, p<0.01) correlation with the components of halitosis. Further, among other factors affecting breath odor, $(CH_3)_2S$ was shown to increase with increased stress. These results indicate that emotional factors, such as stress, should be considered when diagnosing patients with halitosis, and systematic and standardized diagnostic tools should be developed.

In this study, a survey was conducted to check the health status and health-related behavior according to the subjective oral malodor of some university students targeting 1,490 students who are attending N university in Cheonan. Based on the result to confirm the awareness of oral malodor and systemic diseases status, there were many cases to be realized such as sinus infection, chronic rhinitis, asthma, gastrointestinal disorders and xerostama among the people who think that they have bad breath, not the people who think that they don't have bad breath (p<.05). Based on the result to confirm the subjective oral health condition according to awareness of oral malodor status, it was shown that there were more respondents who have some oral conditions such as 'there are tooth to be treated', 'there is food stuck between tooth' and 'the gums are often swollen' among the people who realize that they have bad breath, not the people who think that they don't have bad breath (p<.05). It was shown that there were more cases to be brushed teeth everyday among the people who realize that they don't have bad breath than the people who think that they have bad breath (p<.05) and there were more cases to be used dental floss and to be brushed tongue everyday among the people who think that they don't have bad breath (p<.01).

In order to develop the breeding techniques to increase Hanwoo (Bos taurus coreanae) population, the present study was performed 1) to establish the treatment protocol on reproductive disorders with GnRH or PGF／sub 2$\alpha$／, 2) to improve intraovarian PG $F_{2}$$\alpha$／ administration for reducing open period. Among total of 43 diagnosed, high percentage of cows (41.9％, 18 cows) were diagnosed as silent heat, followed by inactive ovaries (32.6％, 14 cows), ovarian cysts (9.3％, 4 cows), persistent corpus luteum (7.0％, 3 cows), endometriosis (4.7％, 2 cows), pyometra (2.3％, 1 cow) and luteal cysts (2.3％, 1 cow). To treat silent heat, 18 cows were administrated with 25 mg PGF／sub 2$\alpha$／, heat-detected, artificially inseminated and monitored pregnancy. All treated cows were heat-detected and 16 cows (88％) were successfully pregnant. With 200 $\mu\textrm{g}$ GnRH treatment, 7 cows (70％) with inactive ovaries and 3 cows (75％) with ovarian cysts were successfully pregnant. Administration with 25mg PGF／sub 2$\alpha$／, successfully treated 3 cows (100％) with persistent corpus luteum and 1 cow (100％) with luteal cysts, followed by 100％ pregnancy rate. With the combined treatment of 25 mg PG $F_{2}$$\alpha$／and antibiotics, 2 cows (100％) with endometriosis were effectively treated and got pregnant after. artificial insemination (AI). In order to reduce open period, 5 mg PGF／sub 2$\alpha$／ was administrated intraovarian to 20 days cows after delivery, heat-detected, artificially inseminated and monitored pregnancy. In the first experiment, in order to recover uterus, 5mg PGF／sub 2$\alpha$／were administrated, followed by administration of 5mg PGF／sub 2$\alpha$／ at the interval of 14 days. As results, 74％ (17／23 cows) of pregnancy rate after AI. In order to further reduce the open period, 5 mg PGF／sub 2$\alpha$／was administrated at the interval of 11 days without the period of uterus recovery, resulted in 94％ (16／17 cows) pregnancy rate. In conclusion, these results showed that PGF／sub 2$\alpha$／ and GnRH treatment were effective hormonal treatment resume in Hanwoo with various reproductive disorders. In addition, modified protocol of intraovarian PGF／sub 2$\alpha$／ administration could be the effective method for reducing the open period.

This survey was carried out to investigate the occurrence of reproductive disorders in Korean native cattle (Hanwoo). The general management status such as barn type, feed intake, parity and type of reproductive disorders were examined in the Hanwoo farms. In this survey, the total incidence of reproductive disorders that was assessed from 54 Hanwoo farms was 11.6% (73/ 631). We first examined the incidence of reproductive disorders following herd size per farm. The rates of reproductive disorders in under 10 heads, 10 to 20 heads and over 20 heads were 25.2%, 9.4% and 8.3%, respectively (P<0.05). The rate of reproductive disorders in tie stall barn was significantly (P<0.05) higher than that in free stall barn (14.9% vs. 8.1%). The major types of reproductive disorders were follicular cysts (21.8%), fat necrosis (21.8%), and repeat breeding (17.8%). The rate of reproductive disorders assessed by the parity tended to decrease as the parity increased. The relationship between incidence of reproductive disorders and body condition score (BCS) was investigated in 203 Hanwoo. The incidence of reproductive disorder was 80.0%, 8.8%, 9.4%, 10.0%, 33.3% and 57.1% at 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 of BCS, respectively. These data show that the increase of herd size, barn type and BCS affect the incidence of reproductive disorders such as follicular cysts, fat necrosis and repeat breeding in Hanwoo.

This study estimated the degree of uterine inflammation and resumption of ovarian cyclicity in postpartum dairy cows. In addition, the prevalence of health problems during calving and the postpartum period was investigated. A total of 224 Holstein dairy cows from four dairy farms in Chungcheong Province were used for the study. Uterine discharge was scored on a 0 to 5 rank scale (metricheck score) using a metricheck instrument from 1 to 8 weeks postpartum and uterine cytology (neutrophil level) was examined at 4, 6 and 8 weeks postpartum to evaluate uterine inflammation. Resumption of ovarian cyclicity was evaluated based on progesterone analysis (${\geq}1ng/mL$) at 4, 6 and 8 weeks postpartum. Postpartum disorders were diagnosed by veterinarians in the research team. The metricheck score decreased linearly (p < 0.0001) from weeks 1 ($3.4{\pm}0.1$) to 4 ($2.0{\pm}0.1$) postpartum, and then remained at that level through week 8 postpartum ($1.6{\pm}0.1$, p > 0.05). The neutrophil levels determined by uterine cytology assays also decreased (p < 0.0001) from week 4 ($22.3{\pm}1.8%$) to 6 ($12.1{\pm}1.4%$) postpartum, and then remained at that level through week 8 postpartum ($9.2{\pm}1.4%$, p > 0.05). The proportion of cows exhibiting the ovarian cyclicity increased linearly (p < 0.0001) from weeks 2 (12.1%) to 8 (74.3%) postpartum. The prevalence of dystocia and retained placenta were 20.5% and 30.4%, respectively. The prevalence of ketosis, milk fever, abomasal displacement, septicemic metritis, endometritis, subclinical endometritis, pyometra, and ovarian cysts were 18.8%, 3.6%, 4.0%, 36.2%, 29.5%, 17.0%, 4.5%, and 14.7%, respectively. The prevalence of digestive problems and mastitis were 5.4% and 9.6%, respectively. The prevalence of culling and death were 4.0% and 3.6%, respectively. The prevalence of dystocia, retained placenta, septicemic metritis, endometritis, ovarian cysts, digestive problems, mastitis, and culling differed among farms (p < 0.05 to 0.01). In conclusion, proper examinations for uterine inflammation and ovarian cyclicity during 4 to 8 weeks postpartum are useful clinical tools to maintain herd reproductive health. Dystocia, retained placenta, septicemic metritis, and endometritis were predominant disorders in dairy cows of the survey area.
