An 18-month-old, female American Cocker Spaniel was presented with a cataract of left eye. The left eye was blind, and anterior uveitis was noted on ocular examination. Ultrasonography of the eye revealed a hyperechoic mass with distinct borders in the vitreous indicative of lens fiber or mass lesion extending from ciliary body. The eye was enucleated after ultrasonographic examination. On gross examination, rupture of posterior capsule was noted adjacent to the ciliary body.

A two-year-old, intact female Golden Retriever had previously been diagnosed with a portosystemic shunt (PSS) during an ultrasonographic examination at a local animal hospital. The serum biochemistry revealed elevated liver enzymes and bile acid levels. The abdominal radiographic examination revealed mild serosal detail loss and microhepatica, while abdominal ultrasonography revealed mild ascites and high-velocity flow to the caudal vena cava (CVC) suspected as a PSS. The gallbladder was not observed within the hepatic parenchyma during ultrasonography. Computed tomography (CT) revealed an absent gallbladder and dilation of the common bile duct (CBD). Dilations of the gastroduodenal, splenic, colic and renal veins were also observed. A dilated left phrenico-abdominal vein that entered the CVC was previously misinterpreted as a PSS on the ultrasound examination. Based on the imaging examinations, the dog was diagnosed with congenital gallbladder agenesis associated CBD dilation.

The tendon is a dense connective tissue that connects muscle to bone and plays an essential role in joint motion. The injured tendon heals slowly owing to its low cellularity and vascularity. This study aimed to evaluate and compare the effects of regenerative injection therapy (RIT), 20 % dextrose prolotherapy (DP), and platelet-rich plasma (PRP) injections that can promote tendon healing. Twenty-one New Zealand white rabbits were divided into the control, DP, and PRP treatment groups. The superficial digital flexor tendon (SDFT) of the right hindlimb of each rabbit was used. A round defect of 2 mm was induced. Approximately 0.2 mL of 20% dextrose and autologous PRP were injected into the proximal and distal ends of the SDFT mass. Radiographic and ultrasonographic examination and cross-sectional area (CSA) calculations were performed pre-operatively and at 2, 4, and 8 weeks. The SDFT of both limbs was transected for biomechanical and histomorphometric evaluations. The SDFT of the left limb was transected for intact control. Semi-quantitative analysis was performed to evaluate the histomorphometric properties. Additional analysis was performed using H&E, Masson's trichrome, and immunohistochemical staining. The biomechanical evaluation showed that the treatment groups had higher tensile strength compared to the defect control group, while the PRP group had higher tensile strength than the DP group. On histological examination, the treatment groups appeared to be relatively closer to the remodeling phase of the healing process than the defect control group; the characteristics of the PRP group were closer to the remodeling phase than those of the DP group. The ultrasonographic examination showed different tendencies. Increased values in the CSA were observed during the early period in the treatment groups. This study suggests that PRP and DP can promote the healing of tendon injury, and these effects were superior with PRP than that with DP.

A 4-year-old female Shih-tzu with severe episcleral congestion and buphthalmos in left eye was referred to the Veterinary Teaching Hospital, Chonnam National University in October 1998. During two months in local veterinary clinics, the dog had been treated unsuccessfully with tarsorrhaphy and antibiotics. By history taking, cause of the glaucoma was ascertained as accidental nonpenetrated cornea trauma by owner, Ophthalmic examination revealed that the left eye was buphthalmic with severe episcleral congestion, pain and fever. The direct pupillary light response could not be evaluated in the left eye, but right eye had normal reaction. The intraocular pressure was 4.5 mmHg in the right eye and 33 mmHg in the left eye, as measured with a Schiotz tonometer, Ultrasonographic finding revealed hyperechoic vitrous body and central echofree material. The Schirmer tear test showed 20 mm in the left eye and 8 mm in the right eye. The hematologic examination revealed monocytosis. The initial medical treatment was admitted, but there was no response. Transpalpebral enucleation in the left eye under inhalation anesthesia with enflurane 1.2 vol% in oxygen was performed. The day after operation the left eye ravealed no exudate, and pain, and the systemic vital signs were normal. The prognosis is excellent.

This report details a case of post-traumatic pseudocyst in the spleen that was successfully treated with sclerotherapy using ethanol. A sixteen-year-old boy visited our hospital for a follow-up examination of a splenic cyst. He had experienced blunt trauma to the abdomen three years prior to presentation. An abdominal computed tomography scan revealed a large cyst of the lower pole of the spleen. The cyst was $6.8{\times}9.5{\times}7.0cm$ and conservative management was tried. A follow-up ultrasonographic examination three years later revealed that the size of the cyst was unchanged and another treatment was needed to prevent complications. One session of sclerosis with ethanol (90 mL of 99% ethanol) percutaneously was applied to the cyst. A follow-up after four months revealed that the cyst had completely resolved.

This experiment was conducted to find out the therapeutic effect of Artemisia capillaris extracts on hepatic damage in rats induced by carbon tetrachloride ($CCl_{4}$). In this experiment, 96 Sprague-Dawley rats were used as experimental groups, which were divided into 4 groups; control group(A), $CCl_{4}$-treated group(B), $CCl_{4}$+Artemisia extract-treated group(C) and $CCl_{4}$+silymarin-treated group(D). The B, C, D group were administrated single dose of $CCl_{4}$(2.5 ml/kg) to induce acute hepatic injury. C group was administrated with Artemisia capillaris extract(200 mg/kg/day) and D group treated with silymarin(50 mg/kg/day) for 7 days. Hematological, ultrasonographical, histological examinations and examination of antioxidant activity were also performed in all groups. AST and ALT activities of C group were significantly decreased compared with B group. The activities of AST and ALT in C and D groups returned to the normal range more rapidly than those of B group. In ultrasonographic examination, the echogenicity of liver in C group was significantly decreased compared with B group. Also C and D group had tended to recover faster than B group on liver histogram. Histologically, the percentage of degenerative regions and degenerative cell numbers in peri-central vein hepatic parenchyma of C and D group were significantly decreased compared with B group. In examination of lipid peroxidation, malondialdehyde of hepatic tissue in C group was decreased as compared with B group. In examination of antioxidant enzyme activity in liver, glutathione peroxidase and catalase activities were significantly increased compared with B group. As results of this study, it is thought that A. capillaris extract has therapeutic effects on hepatic injury induced by carbon tetrachloride, and has the similar therapeutic effects as silymarin in rats.
