  • We report a case of cat scratch disease (CSD) caused by Bartonella henselae in a 14-year-old boy who developed lymphadenopathy in the right cervical area, after a raising canine pet for 10 months. The cervical lymphadenopathy persisted for 14 days. Immunofluorescent antibody testing for B. henselae with the patient's serum was 1:64 positive. Polymerase chain reaction (PCR) analysis using the patient's lymph node aspirates for B. henselae DNA was also positive. This is the first case of cat scratch disease confirmed by PCR for B. henselae DNA in children.

  • A single i.v. dose of streptozotocin (65 mg/kg) given to rats has produced a marked hyper-glycemia (>500 mg serum glucose/dl). Since the Atractylodis Rhizoma is known to have hypo-glycemic action, the water extracts of Atractylodis Rhizoma (ARWE) was given to the streptozotocin-induced (SZ) hyperglycemic rats. To determine whether ARWE has the anti-hyperglycemic effects, two different daily doses of ARWE (i.e.0.2 g/kg and 2.0 g/kg) were given orally to the SZ rats for up to 8 days. Thereupon, serum levels of glucose, insulin, amylase and cholesterol were determined on days 1, 3 and 8, following the initial and repeated daily administrations of ARWE. On day 8, glycogen content and glucose-6-phosphatase activity in the liver were assayed. Results showed that ARWE decreased the serum glucose levels, which had been markedly elevated by the SZ pre-treatment. In support of this, the serum insulin level, which had been quickly lowered by the SZ pre-treatment $(20{\mu}U/ml)$, was quickly elevated in the ARWE dose dependent manner that, at 2.0 g/kg ARWE, the serum insulin level was increased $(20{\mu}U/ml)$ above the normal level $(42{\mu}U/ml)$. Also, the serum amylase level, which was steadily decreasing after the SZ pre-treatment, was restored to the normal level folowing 8 day of ARWE (2.0 g/kg) treatment. Hepatic glycogen content and glucose-6-phosphatase activity, which decreased and increased, respectively in the 52 treatment group, were restored toward the normal level in SZ plus ARWE group.

  • This studies were carried out to investigate the high infection sites from various specimens, cultural isolation on the susceptible media and specific antibody titres of M. pulmonis in experimental 310 mice and 330 rats obtained from two breeding facilities. Efficiency of complement faxation test (CF test) for detection of M. pulmonis antibody in mice and rats were compared directly with the diagnostic cultural isolation method. 1. Isolation rates of M. pulmonis among infection sites were about 30% from the oral cavities and $40\%$ from the middle ear of mice. The rates were $100\%$from the nasal cavaties and $90\%$ from the oral cavities of rats. 2. The infection rates were $12\%$ to A group and $16\%$ to B group of mice. The rates in the rats were $55\%$ to A group and $70\%$ to B group. 3. The M. pulmonis antibody titres by CF test were $73\%$ of total 100 mice in serum dilution below 1:5 (< 1:5), and $24\%$ of total samples in antibody titres above 1:5 (> 1:5), but 3 samples were not showed anticomplementary activities. The antibody titres in rats were $35\%$ of 120 rats in below 1:5 (< 1:5), and $61\%$ of total samples in above 1:5 (> 1:5), but the remained were not showed anticomplementary activities.

  • To characterize the recent outbreaks of canine distemper (CD) in Korea, we carried out epidemiological investigations by clinical observations, serum neutralizing (SN) antibody titer determination and RT-PCR on the 315 dogs which were clinically suspected as canine distemper virus (CDV) infection. One hundred and sixty two of 315 dogs were infected with CDV. Breed or gender did not seem to have effects on the prevalence of CD. The major part of dogs were in young age from 6 weeks to 18 weeks of age, and were not vaccinated or incompletely vaccinated. Clinical signs of dogs with CD were multi systemic and extremely variable. Dogs died from CD had significantly more ocular signs and neurologic signs than those of dogs survived (p<0.05). The SN titers against CDV of 157 (96.9%) dogs were under 1:16, which is less than protective level. One possible explanation for recent outbreaks of CD in Korea might be low antibody titers against CDV because of vaccination failure. Therefore, to reduce the impact of virulent infection in the dog population, dogs should be vaccinated adequately and prophylactic measures should include isolation of young dogs from the dog population until vaccination can be expected to provide protection.

  • To clarify the requirement of L-ascorbic acid (AsA) in collagen synthesis, the incorporation of 1-$^{14}$ C-proline into the tissues of guinea pigs and the specific radioactivity ratio (proline/hydroxyproline) in collagen were investigated. Male guinea pigs maintained on the AsA-deficient diet were divided into three groups ; group A (AsA-deficient animals) : group B (control animals) supplemented with 5mg AsA/day ; group C (high dose animals) with 300mg AsA/day, and orally supplemented with or with-out AsA for 14 days. Collagen synthesis was estimated by measuring the incorporation of labeled pro-line into collagen in lung and dorsal skin, and the hydroxyproline contents in lung and skin. The AsA contents in the tissues were determined by high-peforrnance liquid chromatography (HPLC), and serum alkaline phosphatase activity was also measured. The serum alkaline phosphatase activity of AsA deficient group was very low as compared with those of AsA supplemented group. Incorporation of labelled proline into collagen and its specific radioactivity ratio in collagen increased with increasing levels of AsA in the tissues. There was a significantly positive relationship between the levels of AsA and hydroxyproline in the tissues.

  • Fumonisin B$_1$ is hepatotoxic in all species, but liver carcinogenic and nephrotoxic in rat. Our objective was to investigate the effects of multiple iv dose of FB$_1$. Male Sprague-Dawley rats were injected intravenously (iv) with FB$_1$ at 1 mg/kg singly (T1), or daily for 2 (T2) or 3 (T3). T1 rats did not show any cytotoxicity in both liver and kidney. However, the most dramatic change occurred in this group was mitotic figures in liver, which increased 5.5-fold to that of control. Hepatotoxic effects were shown in T3, based on histopathology and serum chemistry. A few scattered single cell deaths occurred primarily in the centrilobular area of the liver in T2. Similar but more lesions in liver and a small number of degenerating cells with hypereosinophilic cytoplasm in outer stripe of medulla of kideny were found in T3 rats. Serum chemical profiles included liver enzymes increased, in which cholesterol was very sensitive. This study suggests that multiple exposure of low dose FB$_1$ cause cytotoxic in the liver earlier time point than kideny. FB$_1$$ also stimulates mitosis in liver that may be associated with carcinogenesis.

  • The purpose of this study was designed to observe the effects of the feeding Prunus persica Batsch var. davidiana Max. extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride(TG), phospholipid(PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (groups BCG (cholesterol+water), BCPG (cholesterol+ Prunus persica 5.0 g% extract) than those in the control group (group BG, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remarkably lower in the group BCPG than those in the group BCG. In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Prunus persica 5.0 g% extract administration group was higher percentage than in the group BCG. The activities of aspartate aminotransferase (AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Prunus persica 5.0 g% extract administration group(group BCPG) than in the cholesterol diet group(group BCG). From the above research, Prunus persica Batsch var. davidiana Max. were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Prunus persica Batsch var. davidiana Max. was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

  • The effects of cheonggukjang (traditional fermented soybean food, CK) and cheonggukjang added Phellinus linteus (CKP) on lipid metabolism were investigated in adult male rats. Twenty weeks old Sprague-Dawley rats were fed a purified hyperlipidemic diet (control diet: 0.5% cholesterol, 10% fat, 18% casein) for 4 weeks. The rats were randomly assigned to each treatment group control, two kinds of CK or CKP (powders of CK or CKP as dietary protein sources) After 5 weeks of CK or CKP diets consumption, the body weights, the hepatic and epididymal fat pad weights of the CK or CKP diets groups were significantly decreased than those of the control group. The liver cholesterol and triglyceride levels were significantly lower in both the CK and CKP diets groups than those in the control group. The concentrations in serum triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly decreased in the CK and CKP diets groups compared with those in the control group. The HDL-cholesterol/total-cholesterol ratios were significantly increased in the CK and CKP diets groups compared with those in the control group. Fecal cholesterol and triglyceride excretion of the CK and CKP diets groups were significantly increased than those of the control group. These results showed that both the feeding of cheonggukjang and cheonggukjang added Pheilinus linteus decreased the triglyceride, total cholesterol and LDL-cholesterol in serum as well as the triglyceride and cholesterol in liver, and increased the HDL-cholesterol/total-cholesterol ratio in serum of the rats.

  • A five months old, female Himalayan cat was referred to the Veterinary Medical Teaching Hospital at Konkuk University, because of suspecting peritoneopericardial diaphragmatic hernia (PPDH). After consecutive examination, the patient was diagnosed as PPDH and hepatic dysfunction. In spite of medical therapy for a month, the serum chemistry profiles for liver enzymes (aspartate transferase: 469 U/L, alanine transferase: above analysis, gamma-glutamyl transferase: above analysis) did not decrease to the normal range. In operation, some of liver was necrotized and was adhesive to diaphragm, these were gently dissected from thoracic structures, and resected. After debriding, the edges of the defect of diaphragm were closed with a simple continuous suture pattern. One month after operation, the cat had normal condition, recovery was uncomplicated, and the serum chemistry profiles for liver enzymes decrease to the normal range.

  • Canine coronavirus (CCV) is a cause of sporadic outbreaks of enteritis in dogs. This study was performed to carry out epidemiological investigation on the recent outbreaks of CCV enteritis of dogs and determined the potential prognostic factors affecting the survival of dogs. The 131 (34.4%) out of 381 fecal samples collected from dogs with enteritis were positive for CCV by RT-PCR. The fecal samples contained genotype I (30.5%), genotype II (29.0%), and both genotypes (40.5%) of CCV. The majority of dogs with CCV infection ranged 6-18 weeks of age. Age over 18 weeks was significantly associated with higher survival rate (P < 0.05). Of the clinical signs examined, dogs without anorexia were significantly higher survival rate (P < 0.01). The 90.1% of dogs with CCV infection were co-infected by CCV and CPV-2. From the results of this study, it can be concluded that CCV infection is widespread in the Korean dog population and CCV may be attributed to be one of the important agents causing enteritis in pups.
