Even though the urinary stones are rare in children, careful observation and monitoring are necessary because the incidence has been increasing. This study is aimed to document the characteristics of urinary stones in children including the symptoms, diagnosis, with or without urinary tract infection, other urinary tract anomaly and treatment. 45 patients under the age of 15 years with urinary stones hospitalized during Jan. 1986 to Jun. 1996 at Severance Hospital were reviewed retrospectively. Patients' mean age was 6.5 years and sex ratio (male : female) was 5.4:1. The most common symptom was gross hematuria. Stones accompanied with urinary tract infection was 46.7%, and stones associated with urinary tract anomaly was 35.6%. Extracorporeal shock wave lithotripsy, percutaneous nephrolithotorny, hydration and diuretics were the treatment modality used. Urinary stone were found to be a significant cause of urinary tract obstruction in children, requiring prompt diagnosis and treatment. Although KUB, IVP, and ultrasonography were commonly used to make the diagnosis, many cases were detected only by ultrasonographic study.

A 3-year-old, 43kg, pregnant Great Pyrenese was examined for clinical signs of acute weakness and anorexia for 4 days. The dog was in lateral recumbency at referral. The rectal temperature was within reference range, and the respiratory and heart rates were 36 breaths/min and 58 beats/min, respectively. The abdomen was distended, and several puppies were palpated. The mean fetal head diameter was 2.8cm in the ultrasonographic examination. The initial complete blood count and serum biochemical examinations revealed mild dehydration, mud hyperglycemia, hypochloremia, hyperkalemia, hyponatremia, and low sodium-potassium ratio. Serum BUN and total cholesterol values were slightly high. Hypoadrenocortical crisis was suspected on the basis of signs of acute collapse, hyponatremia and hyperkalemia. Adrenal gland function was evaluated by an ACTH stimulation test. The baseline cortisol concentration was $18.6{\mu}g/dl$ and the concentration at 1 hour after administration of tetracosactrin (ACTH, Synacthen) was $8{\mu}g/dl$. The dog was treated for the correction of assumed hypoadrenocortical crisis and substantial hyperkalemia. In addition to rapid infusion with saline solution, other medications administered intravenously included sodium bicarbonate and cimetidine hydrochloride. The dog was monitored with repeated serum electrolyte examination. After clinical stabilization, cesarean section was performed. All of 13 puppies were delivered, and the dog recovered from anesthesia without complications. The values of postpartum blood tests returned to normal or within reference range. The dog remained healthily.

An 8-years-old intact female shih tzu was referred to the Veterinary Medical Teaching Hospital Chungnam National University for treatment of suspected pyometra. This dog had clinical symptoms of vaginal bleeding, vulvar discharge, polyphagia, polyuria/polydipsia and vomiting. In hematologic examinations, complete blood count (CBC) revealed mild leucopenia and a serum biochemistry profile revealed increased ALP, decreased GLU values. Diagnosis was made by radiographic examination, ultrasonographic examination, abdominocentesis. Peritonitis secondary to pyometra was tentative diagnosed. Surgical treatment was proceeding for ovariohysterectomy and peritoneal saline irrigation. It was confirmed that severe necrotized enteritis and pus leakage to ovarian bursa with pyometra. In this report, secondary severe disease also must be considered in diagnosis of pyometra because septic peritonitis could be occurred by pus leakage from uterus with pyometra.

The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20) were randomly divided into four groups of five heifers/group. Heifers were given a single dose by i.m. administration of 100 mg Follicle Stimulating Hormone dissolved in polyvinylpyrrolidone (FSHp) at 24 h. Ovum pick up (OPU) occurred at 72 h ($F_{24}O_{72}$ protocol; Group 1) or 96 h ($F_{24}O_{96}$ protocol; Group 2), and at 36 h and OPU at 72 h ($F_{36}O_{72}$ protocol; Group 3) or 96 h ($F_{36}O_{96}$ protocol; Group 4) after follicular ablation. The dynamics of ovarian follicular growth were monitored by twice-daily ultrasonographic examinations. Blood sample collections were performed every 12 h after initiation of treatment for assessment of FSH, E2 and P4 profiles. All heifers were subjected to eight repeated sequential sessions of OPU. The follicular deviation commenced $24{\pm}5.32$ h after follicular ablation in all groups. The circulatory FSH surged quickly from 24 to 36 h (>0.8 ng/ml) after follicular ablation and circulatory estrogen levels steadily increased from 36 h until OPU in all groups. At the end of the OPU sessions, the mean number of aspirated follicles/heifer/session in $F_{36}O_{72}$ protocol (Group 3) and $F_{36}O_{96}$ protocol (Group 4) were higher than in the two other groups (p<0.05). The number of cumulus-oocyte complexes (COCs), cleaved and day 8 blastocysts rates in the $F_{36}O_{72}$ protocol (Group 3) were higher than in the other groups (p<0.05). It can be concluded that a single dose i.m. administration of 100 mg FSHp at 36 h and OPU at 72 h after follicular ablation ($F_{36}O_{72}$ protocol; Group 3) was the most effective protocol for superstimulation of follicular growth for repeated OPU and subsequent in vitro embryo production in Thai native heifers.

Production of cloned pigs by somatic cell nuclear transfer (SCNT) has unlimited value for developing critical biotechnology such as xenotransplantation. Various efforts have been made to establish this technology, and several litters of live piglets have been produced after transfer of SCNT embryos. However, the efficiency is very low compared to piglet production by artificial insemination or natural mating. So far, most studies have been limited to in vitro production of SCNT embryos. This study was conducted to standardize a surrogate recipient (gilts) for transfer of SCNT embryos to improve pregnancy rate. Potential surrogate gilts over 7 months of age were checked for their estrous status by observing external signs; vaginal fluid, vulva redness, vulva swelling, and standing response to back pressure. Viscosity of vaginal fluid was evaluated and classified as none (0), medium (1), and strong (2). Vulva redness and swelling was respectively assessed by none or shrink (0), medium (1), strong (2). Back pressure was estimated by an immediate move (0), standing less than 10 sec (1), and standing over 10 see (2). And then ovulation status of each surrogate was classified as pre-ovulation (PO-17 surrogates), just prior to ovulation (JPO-20 surrogates), in ovulation (IO-12 surrogates), just after ovulation (JAO-14 surrogates) and after ovulation (AO-24 surrogates) at the time of surgery for embryo transfer (ET). Real-time ultrasonographic scanners have been used for pregnancy diagnosis by observing amniotic vesicles. The first pregnancy diagnosis was done on Day 30 after ET and then repeated 2-week interval. In the results, SCNT embryos transferred into JPO surrogates gave better pregnancy rates (45%) than others (4% to 11%) on Day 30 after ET. These result indicates that surrogate gilts in a status just prior to ovulation can offer optimal condition to establish pregnancy by transfer of SCNT pig embryos.

Sector scanner which has a conical end is used to image through the intercostal space because heart is protected by the ribs. Cardiac data published all around the world were also obtained by sector scanner. Although scanners being used in every small animal practice and animal hospital at college in Korea include convex ape and linear type, linear type is not appropriate f3r cardiac scan because of a wide contact surface. The purpose of this study is to establish ultrasonographic images of normal cardiac structures by measuring shape, size of reflectable cardiac structure according to restraint position in scanning normal heart of the puppies with 6.5 MHz convex scanner(SonoAce 4500, Medison, Korea) used in our veterinary teaching hospital, Seoul national university. Seventeen male and female puppies considered having healthy hear by X-ray and clinical examination are used feom April to July 1994. Scanning point selection of probe head and the distinction of imaged cardiac structures were accomplished by necropsy and cardiac scanning performed through thoracotomy under general anesthesia. At 10 o'clock position of transducer(at an angle of 30$^{\circ}$ between imaginary line from elbow joint to 3rd sternum and probe head, 60$^{\circ}$ from body surface, 4th intercostal space of right thorax) with the marker of scanner toward the head of dogs right atrium, left atrium and left ventricle were observed in 2, 3, 4, 5 intercostal space(2cm from the sternum) of experimental dog positioned ventrodorsally under general anesthesia. Under these conditions, the numerical values of imaged diastolic hear are as follows : the distance from skin to apex(mean$\pm$S.D) 47.53$\pm$6.94mm, thickness of left ventricular wall 6.00$\pm$1.60mm, length of left ventricle 16.27$\pm$5.31mm, width of left ventricle 15,33$\pm$4.25mm, length of left atrium 12.33$\pm$3.82mm, width of left atrium 11. 33$\pm$3.94mm, length of right atrium 1.00$\pm$2.41mm, width of right atrium 11.21$\pm$2.76mm and the area of left ventricle 270.92$\pm$109.81mm$^2$, area of left atrium 98.00$\pm$41.08mm$^2$, area of right atrium 62.75$\pm$21.04mm$^2$.

Two year-old female miniature schnauzer was presented with depression, abdominal pain and inappetence. Physical examination revealed tachypnea, fever, and abdominal pain. Leukocytosis with neutrophilia was shown in complete blood count. Radiograph revealed the increase of opacity in parallel to vertebra and dislocation of descending colon. Calculi and sludge in bladder, hydronephrosis and dilation of proximal ureter in right kidney were observed in ultrasonographic examination; also, irregular shape of structure in retroperitoneal cavity was observed. Urinalysis showed protein urine and hemtauria. Many epithelial cells, spindle cells, calcium oxalate dihydrate crystals, struvite crystals, amorphous crystals and granular casts, WBC, cocci were examined in urine sediment test. ERD-kit test result was highly positive. Based on those test and excretory urogram pyelonephritis and complete unilateral obstruction of ureter were confirmed. A balloon type structure in retroperitoneal cavity was found through the exploratory laparotomy. In cytologic examination of aspirated fluid from dilated area many degenerated neutrophils and phagocytized cocci were observed. Staphylococcus intermedius was cultured from aspirated fluid. Based on these clinical results retroperitoneal abscesses caused by Staphylococcus intermedius was diagnosed with ureter obstruction and concurrent cystic calculi. Nephrectomy of right kidney with ureter was performed.
