Abstract
Capsosiphon fulvescens (green seaweed) and Hizikia fusiforme (brown seaweed) are marine algae consumed as food supplements, especially in Japan, China and Korea, and are considered traditional medicinal tonics for certain ailments. The aim of this study was to investigate the possible inhibitory effects of dietary C. fulvescens and H. fusiforme on azoxymethane (AOM)-induced colorectal cancer (CRC) in rats. F344 male rats (5 weeks, 150 g) were divided into six groups as follows. Group 1: Injected with normal saline solution and fed control diet (untreated control). Group 2: Injected with AOM and fed control diet (treated control). Group 3: Injected with AOM and fed 1% C. fulvescens diet. Group 4: Injected with AOM and fed 2% C. fulvescens diet. Group 5: Injected with AOM and fed 2% H. fusiforme diet. Group 6: Injected with AOM and fed 6% H. fusiforme diet. Test animals received subcutaneous injections of AOM (15 mg/1 ml/kg body weight) once a week for 2 weeks to induce aberrant crypt foci (ACF) in treated control and experimental groups. We evaluated the effects of dietary C. fulvescens and H. fusiforme at two different dose levels: 1 and 2% C. fulvescens, and 2 and 6% H. fusiforme, on colonic carcinogenesis by AOM in rats. Our results suggest that body weights were not significantly different amongst groups. We found that feeding C. fulvescens and H. fusiforme with a control diet significantly (p<0.05) inhibited the development of ACF in experimental groups. C. fulvescens and H. fusiforme in food also significantly (p<0.05) reduced the proliferating cell nuclear antigen labeling index in the colonic tissues of experimental groups. These results demonstrate the chemopreventive potential of C. fulvescens and H. fusiforme against CRC in an AOM-induced rats.

Abstract
Vitamin C (L-ascorbic acid) is well known as a free radical scavenger that protects cells against damage from oxidative stress. Herein, we investigated the effects of vitamin C against diethylnitrosamine (DEN)-induced hepatotoxicity. Male wild-type (C57BL/6) and senescence marker protein-30 (Smp30) knockout (KO) mice were used and divided in the following four groups: WT group (n=15): Wild-type (WT) mice fed vitamin C-free diet with tap water; WV group (n=14): WT mice fed vitamin C-free diet with water supplemented with 1.5 g/kg vitamin C; KT group (n=12): Smp30 KO mice fed vitamin C-free diet with tap water; and KV group (n=13): Smp30 KO mice fed vitamin C-free diet with water supplemented with 1.5 g/kg vitamin C. A single intraperitoneal injection of DEN (5 mg/kg body weight) was injected in the second week during the experimental period. Mice were sacrificed after 17 weeks of treatment to investigate the effect of dietary vitamin C on DEN-induced hepatotoxicity. The results showed that vitamin C significantly increased the mean lifespan (p<0.05) in the WT, WV and KV groups compared with the KT group. The serum concentrations of γ-glutamyl transpeptidase, alanine aminotransferase, and aspartate aminotransferase did not significantly differ among groups. The WT group exhibited significantly more acute cellular swelling accompanied by centrilobular necrosis, focal lymphocyte infiltration, and eosinophilic intracytoplasmic inclusion bodies as compared with the WV and KV groups, suggesting that vitamin C had a hepatoprotective effect. Dysplastic, large, and binucleated hepatocytes were also observed in the WT group, but these pathological signs were absent from the WV and KV groups. Our experimental evidence suggests that vitamin C supplementation in Smp30 KO mice was effective for the treatment of DEN-induced hepatotoxicity.

Abstract
A 5 yr old, 184 kg, and 262 cm total length female bottlenose dolphin Tursiops truncatus was found dead in a display after bloody discharge from the blowhole was observed 3 h prior to death. Pathological examination revealed fibrinous bronchopneumonia with prominent areas of necrosis (sequestra) and numerous Gram-negative bacilli within alveoli and in blood vessels of the lungs and liver and between muscle fibers. The cause of death was attributed to septicemia. Often, cases of fibrinous bronchopneumonia are characterized by bacteremia in the latter stages of infection, resulting in the death of the animal. Septicemia likely accounts for the ecchymoses and petechiae noted on the spleen, pancreas, forestomach, lungs, visceral peritoneum, and small intestine. Additional lesions included hemothorax, stable red frothy fluid in the trachea, and lymphoid depletion in the spleen and lymph nodes. Pure growth of Morganella morganii was isolated from the lungs, blood, liver, and blowhole mucosa. Sequencing of 16s rRNA of the isolated bacteria showed more than 99.6% identity with M. morganii strain FDAARGOS_172. To our knowledge, this is the first report of fatal fibrinonecrotizing bronchopneumonia associated with M. morganii infection in a cetacean.

Abstract
AIM The aim was to study whether oral glucosamine hydrochloride (GlcN.HCl) or mucopolysaccharide protein (MucoP) has a structure-modifying effect on an anterior cruciate ligament transection (ACLT) rabbit model of osteoarthritis (OA). METHODS OA was surgically induced in the right knees of rabbits by transection of the ACLT. The left knees served as a sham-operated control. The animals were divided into four groups (n = 6 each): negative control (phosphate buffered saline, orally), positive control (oral celecoxib 10 mg/kg body weight/day), GlcN.HCl (oral 100 mg/kg/day) and MucoP (oral 100 mg/kg/day). Experimental animals were sacrificed after 8 weeks of treatment and the distal femur was removed for macroscopic examination, histological assessment, and terminal deoxynucleotidyl transferase-mediated nick-end labeling (TUNEL) assay of the OA rabbits. RESULTS On gross morphology, severe lesions were observed in articular cartilage in the negative control group. In the GlcN.HCl and MucoP treatment groups, fibrillations and cartilaginous lesions were significantly (P < 0.05) decreased compared to the negative control group. In particular, degenerative changes in cartilage and chondrocyte cellularity were significantly reduced (P < 0.05) in the positive control (celecoxib) group, GlcN.HCl treatment group and MucoP treatment group compared with the negative control group. TUNEL assay showed that apoptotic chondrocytes were significantly suppressed in the celecoxib group. Similar significant (P < 0.05) results were seen in the GlcN.HCl group and MucoP group but apoptosis of chondrocytes were high in the negative control group. CONCLUSION These data suggest that the protective effects of GlcN.HCl and MucoP may play a useful role in the clinical treatment of OA.
