Background: Inflammatory hematological parameters like the neutrophil/lymphocyte (N/L) ratio have been investigated in many cancer types and significant relationships found with prognosis, for example. The aim of this present study was to investigate the impact of hematological parameters notably on N/L ratio and mean platelet volume (MPV) in papillary thyroid cancer cases. Materials and Methods: A total of 79 patients who underwent a thyroidectomy operation in Findikli, Goiter Research and Treatment Center during 2011-2015 period were enrolled in the study, 41 with papillary thyroid cancer and 38 with benign goiter confirmed by pathological examination. We collected clinical and laboratory data for the patients from hospital records retrospectively. Blood samples taken at admission were assessed for parameters compared between the groups. Results: No significant differences between papillary thyroid cancer and benign goiter groups were apparent in terms of age, the N/L ratio, MPV, white blood cell count (WBC), red blood cell count (RBC), hemoglobin, hematocrit, platelet, neutrophil, lymphocyte, red blood cell distribution width (RDW) and platelet crit (PCT) levels (p>0.05). Only the level of platelet distribution width (PDW) significantly differed, being lower in the papillary cancer group (p<0.05). Conclusions: No significant relationship between papillary thyroid cancer and inflammatory hematological parameters including in particular the N/L ratio and MPV. The relevance of the PDW values remains unclear.

Aloe-emodin (AE), a natural anthraquinone compound, has been reported to exhibit anticancer activity in various cancer cell lines and anti-inflammatory effects in murine macrophages. In the present study, we investigated the cancer chemopreventive effects of AE in an Apc-deficient Min mouse model. In the first experiment, male Min mice were fed a basal diet or diets containing 5 ppm AE and 10 ppm AE for 12 weeks. The dietary administration of 5 ppm AE significantly reduced the number of colorectal tumors. In a second experiment, we investigated the effects of AE on colitis-related colon carcinogenesis in Min mouse treated with dextran sodium sulfate (DSS). Female Min mice were administered 1% DSS in their drinking water for 7 days. AE was given to mice in their diet at a dose of 5 or 50 ppm for 5 weeks. Feeding with AE significantly reduced the number of colorectal tumors. When proliferation of cells in normal-appearing colonic mucosa was assessed by monoclonal anti-rat Ki-67 antibody (MIB-5) immunohistochemistry in experiments 1 and 2, the AE treatment significantly decreased the mean MIB-5-labeling index. These results suggest that the dietary administration of low-dose AE may have chemopreventive effects against development of colorectal tumors in Min mice, possibly in part by reducing cell proliferation in colorectal mucosa.

Hypoglycemic effect of Tabebuia avellandae was investigated in the streptozotocin(STZ)-induced diabetic rats. Diabetes was induced in male Sprague-Dawley rats by injections of STZ (45 mg/kg, i.v.). Rats weighing 200-250 g were divided into 6 groups: normal, STZ-control, hexane fr., CHCl$_3$fr., BuOH fr. and $H_2O$ fr. group. Normal and STZ-control rats received 3% Tween 80 only. Four groups of diabetic rats were administered orally at doses of 100, 400, 300 and 400 mg/kg/day of hexane, CHC1$_3$, BuOH and $H_2O$ fr. respectively. Fractions were administered orally to the rats for 7 days after STZ injection. All rats were anesthetized with ether, blood samples were taken by cardiac puncture for clinical chemistry and the rats were killed by exsanguination. Liver, kidney, heart and spleen were removed, weighed and analyzed. We measured glucose, protein, cholesterol and triglyceride levels in the plasma and glycogen, cholesterol and triglyceride levels in liver. The extent of blood glucose decrement in rats administered $H_2O$ fraction was greater than that in the STZ-control rats. The serum cholesterol and triglyceride levels were significantly lowered by administration of $H_2O$ fraction compared with those of STZ-control group. Treatment of rats with Tabebuia avellandae fractions caused decreases in STZ-induced elevation of cholesterol and triglyceride. Liver triglyceride level was significantly lowered hexane and BuOH fraction group compared with STZ-control group. These results suggest that $H_2O$ fraction of Tabebuia avellandae has the hypoglycemic action against STZ-induced diabetic rats.

A 4-year-old spayed female, Yorkshire terrier dog with a history of petechial and ecchymotic hemorrhages on the face, trunk and hind limb was referred to Veterinary Medical Teaching Hospital, Cheju National University. The complete blood count revealed a marked thrombocytopenia ($96{\times}10^3/{\mu}l$). The biochemical profile showed only slightly increased glucose. The coagulation profile such as prothrombin time and activated partial thromboplastin time, was within the reference range. In Giemsa staining, there were no endoparasites like as Babesia spp. on the RBC. This case was diagnosed as a idiopathic thrombocytopenia in a Yorkshire terrier dog. She was treated with prednisone (1 mg/kg BW, IM q 12 h) and cephalosporin (10 mg/kg BW, IM, q 12 h). When rechecked on day 6, the platelet was within reference range ($507{\times}10^3/{\mu}l$) and also petechial and ecchymotic hemorrhages on the body were gradually improved without any complications. The dose of prednisone was decreased to 0.5 mg/kg BW, q 24 h. On day 17, we finished treatment because all the clinical signs, blood and serum chemistry were reference range and platelet count was dramatically increased.

This research is to estimate the toxicity of Atractylodis Rhizoma Alba (ARA) in F344 rats and to find a dose level for the 13 weeks toxicity study. A hot water extract of ARA (ARWE) was administered orally to F344 rats at dose levels of 0 (vehicle control), 500, 1000, 2000, 3500, and 5000 mg/kg/day for 2 weeks. Each group was composed to five male and five female F344 rats. According to the result, there were no ARWE-related adverse changes in mortality, body weights, food consumption, urinalysis, hematology, clinical chemistry, gross finding at necropsy, and organ weight examination. Salivation was observed in 3500 and 5000 mg/kg/day in male and female rats but it could not have found any relationship with ARWE administration. Based on our findings, ARWE may not cause toxicity in rats under the experimental conditions. Therefore, dose level of 5000 mg/kg/day as a highest treatment group in 13-week exposure study is recommended for further toxicity assessment.

Echocardiography, vital signs, microfilaremia, and blood chemistry of 12 Jindo dogs naturally infected with canine heartworms (Dirofilaria immitis) were analysed and compared with those of 5 uninfected control Jindo dogs. Nine of the twelve infected dogs contained microfiaria in the peripheral blood, whereas the presence of adult heartworms in the pulmonary arteries and/or in the heart was detected from four dogs by echocardiography. Among the four echocardiography-positive dogs, two dogs also displayed evidence of heartworms in the right ventricle by echocardiography. Upon necropsy, a total of 547 adult worms was collected from the 12 infected dogs (av = 45.6, range = 9-166). Dogs with positive echocardiograpic images of heartworms contained 48, 74, 104 and 166 adult worms in the heart, pulmonary arteries and/or in the caudal vena cava (av. 98.0), whereas 9 to 39 worms (av. 19.4) were collected from those organs of dogs with negative echocardiography. Most heartworms were found in the right ventricle (438, 80%) at necropsy, whereas relatively fewer worms were found in the pulmonary arteries (96, 17.6%), and in the caudal vena cava (13, 2.4%). The necropsy findings on the location of adult worms significantly differed from the results of echocardiographic analysis in which the right ventricle of most dogs did not show the presence of heartworms. These results indicated that the adult heartworms had been located in the terminal branches of the pulmonary arteries when the host was alive, but the worms moved toward the right ventricle shortly after the heart of the infected dogs stopped beating. Microfilaremia in the peripheral blood was the highest in the blood samples collected at 10 pm. However, the correlation between the number of microfilaria and of adult worms was not observed. Clinical and vital signs of infected dogs did not show any significant difference before and after a 30 minute-exercise at 5 km/hr compared to those of uninfected control dogs.

This experiment was carried out to study the toxic effect of solublized methylcellulose (MC). Sprague-Dawley rats were dosed with 1%(w/v) MC in 0.9% saline by gavage at a dose of 10ml/kg b.w/day or by intravenous injection at a dose of 5ml/kg b.w/day for 28 days. Clinical signs were observed once a day. Body weights, water and food consumptions were measured and urinalysis was performed several times during the experiment. Rats were sacrificed on days 3, 7, 15 and 28 for hematology, blood chemistry, organ weights and histopathology. The relative weight of the spleen and foamy cells of the spleen were increased in the gavage group. Body weight gain, food consumptions, the values of RBC, Hb, MCH, Hct, serum proteins, glucose, bilirubin, AST, and ALP were decreased in I.V. treatment group. On the other hand, water consumptions, the values of serum cholesterol, creatinine, and BUN were increased. Microscopic findings were granulomas, distended sinusoids, and hypertrophy of Kupffer cells with vacuoles in the liver. Spleen exhibited granuloma, increased extramedullary hematopoiesis, and congestion. Kidney exhibited foamy cells in the glomeruli, distension of the tubules. The findings appeared more severe when the treatment was extended. In conclusion, MC solution is not a safe vehicle for intravenous administration because of the toxic effects on the liver, kidney and spleen. In addition, a long-term and large dosage of oral administration of MC appears to be unsafe also and needs to be investigated further.

Objectives : This study investigated the hepatoprotective effect of herbal mixture including Lycii fructus (HML) in thioacetamide (TAA)-induced hepatotoxicity in mice. Methods : To confirm the liver protective effect, induced by TAA for 3 days injection at 100 mg/kg mice, HML were treated for 8 weeks at 300 mg/kg/day, 1000 mg/kg/day. Positive control was treated silymarin 50 mg/kg/day after TAA injection. The changes of mortality rate, clinical signs, organ weight, relative liver, blood chemistry and histopathological findings were analyzed after experiment. Results : Body weight gain was observed in all groups, but TAA treated group at 4th week and all treated groups decreased weight compared to the untreated group. As a result of organ weight measurement, organ weight gain due to hepatic injury was observed statistically significantly in TAA-treated group and TAA+Silymarin treated group, and the herbal mixture-treated group showed a tendency to decrease compared to the TAA treated group. Blood biochemistry showed that total cholesterol and very low density lipoprotein cholesterol decreased statistically in TAA+low-dose and high dose herbal mixture treated group compared to the TAA-treated group. Histopathological examination showed that liver abnormalities were not observed in untreated group, liver fibrosis was observed in liver injury with TAA treated and herbal mixture treated group. And, TAA+high dose herbal mixture group showed relaxation tendency on liver calcification compared to the TAA treated group. Conclusions : According to the above results, HML provided hepatoprotective effects on the hepatic injury by reduction of inflammatory responses.

A 5-year-old, female Poodle and her daughter, 2-year-old, were referred to Konkuk University Veterinary Teaching Hospital (KVTH) due to discoloration of hair on dorsum, and generalized alopecia following clipping. Some papules and pustules are found on patch area. Complete blood counts and serum chemistry profiles were not remarkable. Trichogram revealed that melanin-granule was pigmented on hair bulb and shaft in affected area and no melanin pigmentation was noted in non-patch area. And skin biopsy showed mild epidermal hyperplasia and mild inflammation in dermis of the patch area. This case report indicates that melanotrichia can be occurred by postclipping inflammation. However, the mechanism of melanocyte proliferation and rates of melanogenesis in response to postclipping remains to be unclear in these cases.
